Lebedev, "Separation of a 3He-4He mixture by low-temperature rectification," Chem. Pet.

Из уровня техники известно устройство для получения 3Не из природного гелия, которое содержит ректификационную колонну, разделенную на верхнюю секцию меньшего диаметра и нижнюю секцию большего диаметра, причем нижняя секция снабжена каналом ввода природного гелия и каналом отвода природного гелия с уменьшенной концентрацией 3Не, а верхняя секция снабжена каналом отвода концентрата 3Не.

[Патент на изобретение US N°8671715, дата публикации 18.03.2014] The prior art device for producing 3 Not from natural helium, which contains a distillation column divided into an upper section of a smaller diameter and a lower section of a larger diameter, the lower section is provided with a channel for input of natural helium and a channel for removal of natural helium with a reduced concentration of 3 He, and the upper section is provided with a 3 He concentrate discharge channel. The distillation column is also equipped with a condenser located in the upper part of the lower section. [Patent for invention US N ° 8671715, publication date 03/18/2014]
Недостатком данного решения являются высокие энергозатраты, что обусловлено использованием в качестве сырья природного гелия, концентрация 3Не в котором составляет 0,00001-0,0002%, что приводит к необходимости многократной ректификации, вследствие чего возрастают удельные энергетические затраты. Из уровня техники известно устройство для получения концентрата 3Не, которое содержит криостат, внутри которого расположены две ёмкости, полости которых соединены между собой фильтром, причем первая ёмкость соединена с каналом ввода природного гелия и каналом отвода концентрата 3Не, а вторая ёмкость соединена с каналом отвода 4Не и снабжена нагревателем. [А. М. Архаров, В. В. Барышников и др., Низкотемпературный метод повышения концентрации легкого изотопа 3Не в смеси 3Не- 4Не природной концентрации, год публикации 1993] The disadvantage of this solution is the high energy consumption, which is due to the use of natural helium as a raw material, the concentration of 3 He in which is 0.00001-0.0002%, which leads to the need for multiple rectification, resulting in increased specific energy costs. The prior art device for producing 3 He concentrate, which contains a cryostat, inside which there are two containers, the cavities of which are connected to each other by a filter, the first tank being connected to the natural helium input channel and the 3 He concentrate removal channel, and the second tank connected to the channel 4 He outlet and equipped with a heater. [BUT. M. Arkharov, VV Baryshnikov et al., Low-temperature method for increasing the concentration of light isotope 3 Not in a mixture of 3 He- 4 Not of natural concentration, publication year 1993]
Недостатком прототипа являются высокие энергозатраты, обусловленные тем, что фильтрацию производят путём нагрева второй ёмкости. Это приводит к тому, что в процессе фильтрации тепловыделения происходят в обеих ёмкостях, вследствие чего нагрузка на средства охлаждения криостата растёт. The disadvantage of the prototype is the high energy consumption due to the fact that the filtration is carried out by heating the second tank. This leads to the fact that during the filtering process heat dissipation occurs in both tanks, as a result of which the load on the cooling means of the cryostat increases.
Техническая проблема, на решение которой направлено заявляемо изобретение, заключается в повышении энергоэффективности устройства для получения концентрата 3Не. The technical problem to which the claimed invention is directed is to increase the energy efficiency of the device for producing 3 He concentrate.
Технический результат, достигаемый заявляемым изобретением, заключается в снижении энергозатрат на термостатирование в процессе получения концентрата 3Не. The technical result achieved by the claimed invention is to reduce the energy consumption for temperature control in the process of obtaining 3 He concentrate.
Сущность заявляемого изобретения заключается в следующем. The essence of the claimed invention is as follows.
Устройство для получения концентрата 3Не содержит криостат, внутри которого расположены две ёмкости, полости которых соединены между собой фильтром, причем первая ёмкость соединена с каналом ввода природного гелия и каналом отвода концентрата 3Не, а вторая ёмкость соединена с каналом отвода 4Не. В отличие от прототипа устройство снабжено средством нагнетания давления, оказываемого на фильтр природным гелием. Device for producing concentrate 3 Does not contain a cryostat, inside of which there are two containers, the cavities of which are connected to each other by a filter, the first container being connected to the natural helium input channel and the 3 He concentrate removal channel, and the second container connected to the 4 He removal channel. In contrast to the prototype, the device is equipped with a means of pumping pressure exerted on the filter with natural helium.
Средство нагнетания давления, оказываемого на фильтр природным гелием, может быть представлено, например, в виде криогенного насоса, сопла, канала отвода испарений криоагента с нагнетателем. The means for pressurizing the pressure exerted on the filter with natural helium can be presented, for example, in the form of a cryogenic pump, nozzle, and channel for removing the vapor of the cryoagent with a supercharger.
Криогенный насос может быть расположен в канале ввода природного гелия и может обеспечивать повышение скорости перемещения потока жидкого природного гелия по каналу ввода природного гелия. The cryogenic pump can be located in the channel of input of natural helium and can provide an increase in the speed of movement of the flow of liquid natural helium through the channel of input of natural helium.
Сопло может быть выполнено на выходе канала ввода природного гелия, обеспечивая повышение выходной скорости потока жидкого природного гелия. Канал отвода испарений криоагента с нагнетателем может соединять криостат с сосудом источника подачи природного гелия для транспортировки испарений криоагента, содержащегося в криостате, в него, обеспечивая наддув испарений криоагента в сосуд источника подачи природного гелия, что приведет к нагнетанию давления в сосуде и повышению выходного давления, подаваемого в первую ёмкость природного гелия. Нагнетатель представляет собой последовательно соединенные вакуумный насос и компрессор. The nozzle can be made at the output of the input channel of natural helium, providing an increase in the output flow rate of liquid natural helium. The channel for venting the cryoagent vapors with a supercharger can connect the cryostat with the vessel of the natural helium supply source to transport the vapor of the cryoagent contained in the cryostat into it, providing pressurization of the cryoagent vapors in the vessel of the natural helium supply source, which will lead to pumping pressure in the vessel and increasing the output pressure, fed into the first tank of natural helium. The supercharger is a series-connected vacuum pump and compressor.
Также средство нагнетания давления может быть выполнено рядом с источником подачи природного гелия, например, в качестве таких средств может быть использован дополнительный баллон с газообразным природным гелием или нагреватель. Also, a means of pressurization can be performed near the source of supply of natural helium, for example, an additional balloon with gaseous natural helium or a heater can be used as such means.
Баллон с газообразным природным гелием обеспечивает наддув газообразного природного гелия над зеркалом жидкого природного гелия в сосуде источника подачи природного гелия, что приводит к нагнетанию давления в сосуде и повышению выходного давления, подаваемого в первую ёмкость природного гелия. При этом в качестве баллона могут быть использованы известные сосуды под избыточным давлением, предназначенные для транспортировки и хранения газов. A cylinder with gaseous natural helium provides pressurization of gaseous natural helium over a mirror of liquid natural helium in a vessel of a natural helium supply source, which leads to an increase in pressure in the vessel and an increase in the outlet pressure supplied to the first natural helium tank. At the same time, well-known pressure vessels intended for transporting and storing gases can be used as a cylinder.
Нагреватель обеспечивает нагрев и испарение части жидкого природного гелия в источнике подачи природного гелия, что также позволяет повысить давление в сосуде и увеличить выходное давление подаваемого в первую ёмкость природного гелия. The heater provides heating and evaporation of part of the liquid natural helium in the source of supply of natural helium, which also allows you to increase the pressure in the vessel and increase the output pressure supplied to the first tank of natural helium.
Первая и вторая ёмкости могут иметь различную форму и размеры, но при этом должна обеспечиваться их герметичность, что необходимо для исключения риска утечки сверхтекучего 4Не в процессе фильтрации. The first and second tanks can have different shapes and sizes, but at the same time their tightness must be ensured, which is necessary to eliminate the risk of leakage of superfluid 4 Not in the filtering process.
Фильтр может быть выполнен в виде пористого материала, с размерами пор от 0,1 до 20 мкм, что обусловлено характеристикой движения сверхтекучего 4Не, и снабжен оболочкой, предназначенной для предотвращения взаимодействия фильтруемого материала с окружающей средой. Фильтр может быть выполнен из спрессованного угля, спеченной оксидной пудры АЬОз или SiC. Фильтр расположен между первой и второй ёмкостями, тем самым образуя соединение между их полостями и обеспечивая возможность перетекания фильтруемого материала из одной емкости в другую. The filter can be made in the form of a porous material, with pore sizes from 0.1 to 20 μm, which is due to the motion characteristic of the superfluid 4 He, and is equipped with a shell designed to prevent the interaction of the filtered material with the environment. The filter may be made of compressed coal, sintered oxide powder AO3 or SiC. The filter is located between the first and second containers, thereby forming a connection between their cavities and allowing the filtered material to flow from one container to another.
Криостат исполняет роль корпуса устройства для получения концентрата 3Не, и выполнен с возможностью поддержания температуры достаточной для перехода 4Не в сверхтекучее состояние. В качестве него могут быть использованы криостаты с известными криоагентами и средствами охлаждения, например, в качестве криоагента может быть использован гелий, а в качестве средств охлаждения криостата может быть использован магнитный рефрижератор, каскад холодных вакуумных нагнетателей или средства, обеспечивающие вакуумную откачку паров насыщенной жидкости. The cryostat plays the role of a device casing for producing 3 He concentrate, and is configured to maintain a temperature sufficient to transfer 4 He to a superfluid state. As it can be used cryostats with known cryoagents and cooling means, for example, helium can be used as a cryoagent, and a magnetic refrigerator, a cascade of cold vacuum superchargers, or means providing a vacuum pumping out of saturated liquid vapor can be used as a cryostat cooling means.
Источник природного гелия может быть выполнен в виде известных устройств, предназначенных для хранения и транспортировки криогенных жидкостей и газов. Возможно выполнение источника природного гелия в виде сосуда Дьюара, либо в виде комплекса устройств, состоящего из баллонов с газообразным природным гелием и ожижителя. При этом во время работы устройства для получения концентрата 3Не источник природного гелия соединен с каналом ввода природного гелия, что необходимо для подачи природного гелия в устройство. The source of natural helium can be made in the form of known devices designed for storage and transportation of cryogenic liquids and gases. It is possible to produce a source of natural helium in the form of a Dewar vessel, or in the form of a complex of devices consisting of cylinders with gaseous natural helium and a fluidizer. Moreover, during operation of the device for producing 3 He concentrate, the source of natural helium is connected to the input channel of natural helium, which is necessary for supplying natural helium to the device.
Заявляемое изобретение обладает новым отличительным существенным признаком, который заключается в том, что устройство снабжено средством нагнетания давления, оказываемого на фильтр природным гелием. Это позволяет исключить необходимость нагрева второй ёмкости, при этом обеспечивая возникновение движения сверхтекучего 4Не через фильтр за счёт механокалорического эффекта, создаваемого вследствие повышения давления жидкого природного гелия на фильтр, что позволяет снизить тепловыделения во второй ёмкости. Также исключение необходимости нагрева второй ёмкости приводит к снижению тепловыделений, возникающих в процессе выведения 4Не из второй ёмкости через канал отвода 4Не, так как температура выводимого 4Не не будет превышать температуру криоагента в криостате. Совокупное снижение тепловыделения во второй ёмкости и канале отвода 4Не позволяет значительно снизить нагрузку на криостат, благодаря чему достигается технический результат, который заключается в снижении энергозатрат на термостатирование в процессе получения концентрата 3Не, что позволяет повысить энергоэффективность устройства для получения концентрата 3Не. The claimed invention has a new distinctive essential feature, which consists in the fact that the device is equipped with a means of pumping the pressure exerted on the filter with natural helium. This eliminates the need for heating the second tank, while ensuring the occurrence of the movement of superfluid 4 He through the filter due to the mechanocaloric effect created by increasing the pressure of liquid natural helium on the filter, which allows to reduce heat generation in the second tank. Also, the elimination of the need to heat the second tank leads to a decrease in the heat generated during the removal of 4 He from the second tank through the 4 He channel, since the temperature of the 4 He will not exceed the temperature of the cryoagent in the cryostat. The combined decrease in heat generation in the second tank and the exhaust channel 4 does not significantly reduce the load on the cryostat, which results in a technical result, which consists in reducing the energy consumption for temperature control in the process of obtaining 3 He concentrate, which improves the energy efficiency of the device for producing 3 He concentrate.
Наличие нового отличительного существенного признака свидетельствует о соответствии заявляемого изобретения критерию патентоспособности «новизна». The presence of a new distinctive essential feature indicates compliance of the claimed invention with the patentability criterion of "novelty."
Раннее из уровня техники не было известно влияние нового отличительного существенного признака на заявляемый технический результат, что свидетельствует о соответствии заявляемого изобретения критерию патентоспособности «изобретательский уровень». Заявляемое изобретение может быть выполнено из известных материалов с помощью известных средств, что свидетельствует о соответствии заявляемого изобретения критерию патентоспособности «промышленная применимость». Earlier in the prior art, the influence of the new distinctive essential feature on the claimed technical result was not known, which indicates the compliance of the claimed invention with the patentability criterion of "inventive step". The claimed invention can be made of known materials using known means, which indicates the compliance of the claimed invention with the patentability criterion of "industrial applicability".
Заявляемое изобретение может быть дополнительно снабжено нагревателем во второй емкости, что позволит повысить интенсивность извлечения 4Не в процессе получения концентрата 3Не. Причем энергозатраты на термостатирование также могут быть снижены за счет меньшего нагрева второй ёмкости, так как комбинированное применение нагревателя и средства нагнетания давления исключает потребность её нагрева до раннее применяемых высоких температур. The invention can be additionally equipped with a heater in the second tank, which will increase the intensity of extraction of 4 He in the process of obtaining 3 He concentrate. Moreover, the energy consumption for temperature control can also be reduced due to less heating of the second tank, since the combined use of a heater and a means of pumping pressure eliminates the need for heating to the previously applied high temperatures.

In FIG. 1 and FIG. 2 shows a device for producing 3 He concentrate, which contains a cryostat 1, inside of which there are two containers, the cavities of which are connected to each other by a filter 2, the first tank 3 being connected to a natural helium input channel 4 and a 3 He concentrate discharge channel 5, and the second tank 6 is connected to the channel 7 of the outlet 4 He, and the device is equipped with means 8 for pressurization. The first tank 3 serves natural helium through the channel 4 input natural helium, and the means 8 for pressurization provides an increase in pressure exerted on the filter 2 with natural helium. The pressure exerted by natural helium on filter 2 leads to the overflow of superfluid 4 He through filter 2 from the first tank 3 to the second tank 6.
На Фиг. 3 изображено устройство, которое дополнительно снабжено нагревателем 9. В первую ёмкость 3 подают природный гелий по каналу 4 ввода природного гелия, причем средство 8 нагнетания давления обеспечивает повышение давления, оказываемого на фильтр 2 природным гелием. В то врем как во второй ёмкости 6 производят нагрев при помощи нагревателя 9. Совокупное повышение давления, оказываемого на фильтр 2 природным гелием, с повышением температуры во второй ёмкости 6, приводит к перетеканию сверхтекучего 4Не через фильтр 2 из первой ёмкости 3 во вторую ёмкость 6. In FIG. 3 shows a device that is additionally equipped with a heater 9. Natural helium is supplied to the first tank 3 through a channel for introducing natural helium, the pressure pumping means 8 increasing the pressure exerted on the filter 2 with natural helium. While in the second tank 6, heating is performed using the heater 9. The combined increase in pressure exerted on the filter 2 natural helium, with increasing temperature in the second tank 6, leads to the overflow of superfluid 4 He through the filter 2 from the first tank 3 to the second tank 6.
В процессе работы устройства производят постоянную подачу природного гелия по каналу 4 ввода природного гелия, откачку 4Не из второй ёмкости 6 по каналу 7 отвода 4Не, а также отбор концентрата 3Не из первой ёмкости 3 по каналу 5 отвода концентрата 3Не. In the process, the device produces a constant supply of natural helium through channel 4 for introducing natural helium, pumping 4 He from the second tank 6 through channel 7 of the 4 He outlet, and also selecting 3 He concentrate from the first tank 3 through channel 5 of the 3 He concentrate discharge.
Таким образом, наличие средства нагнетания давления позволяет достичь технический результат, который заключается в снижении энергозатрат на термостатироване в процессе получения концентрата 3Не. Thus, the presence of a means of pressurization allows you to achieve a technical result, which is to reduce energy consumption at thermostated in the process of obtaining concentrate 3 He.
