Description
Изобретение относитс к кавита- ционным реакторам и предназначено дл использовани в целлнхпозно-бу- мажной промьшшенности, в технике обработки жидких систем (растворов, эмульсий, суспензий).The invention relates to cavitation reactors and is intended for use in the cellulose and paper industry in the treatment of liquid systems (solutions, emulsions, suspensions).
Цель.изобретени - повьшение качества обрабатываемой смеси за счет увеличени эрозионной активности кавитационного пол .The purpose of the invention is to improve the quality of the processed mixture by increasing the erosion activity of the cavitation floor.
На чертеже изображен гкавитацион- ный реактор.The drawing depicts a hydration reactor.
Кавитационный реактор включает цилиндрическую камеру 1 с патрубками 2 и- 3 дл ;прдачи-обрабатываемой смеси и. отвЬда; ее после обработки соответственно и установленный в камере кавитатор 4, имеющий рабочую поверхностБ 5 дл образовани на ней пограничного сло смеси и вьтол- ненный в виде усеченного конуса, обращенного большим основанием 6 в сторону патрубка дл отвода смеси, кавитатор выполнен полым и имеет со стороны большего основани снабженный регул тором 7 патрубок 8 дл заполнени полости жидкостью, а на рабочей поверхности отверсти 9 дл подачи жидкости из полости в пограничный слой.Cavitation reactor includes a cylindrical chamber 1 with nozzles 2 and 3 for; transfer the processed mixture and. out; after processing, respectively, a cavitator 4 installed in the chamber, having a working surface 5 for forming a boundary layer of the mixture on it and embedded as a truncated cone turned by a large base 6 towards the branch pipe to discharge the mixture, the cavitator is hollow and has the base is provided with a regulator 7, a nozzle 8 for filling the cavity with liquid, and on the working surface of the opening 9 for supplying liquid from the cavity to the boundary layer.
Реактор работает следующим образом .The reactor operates as follows.
Обрабатываема жидка технологическа среда поступает в проточную камеру-1 со скоростью 8-12 м/с, обтекает кавитатор 4, за которым образуетс кавитационна суперкаверна , при смыкании которой образуютс кавитационные пол схлопывающихс микропузырьков. Больща часть кави- тационных пузырьков генерируетс в пограничном слое на поверхности 5 кавитатора 4 и по. поверхности супер- .каверны сноситс в ее хвостовую зону . По трубопроводу через патрубок 8 в пограничньй слой через отверсти 9 на поверхности кавитатора подводитс регулируемое количество жидкости (регулировка производитс , например.The processed process fluid enters the flow chamber-1 at a speed of 8-12 m / s, flows around the cavitator 4, behind which a cavitation supercover is formed, during the closure of which the cavitation fields of collapsing micro bubbles form. Most of the cavitation bubbles are generated in the boundary layer on the surface 5 of the cavitator 4 and along. the surface of the supercavity is blown into its tail area. A pipeline through the pipe 8 into the boundary layer through the holes 9 on the surface of the cavitator is supplied with an adjustable amount of liquid (adjustment is made, for example.

регул тором 7). В результате подвода жидкости в пограничный слой его толщина и турбулентность увеличиваетс , что приводит к увеличению ко- 5 личества пузырьков и их размеров в сход щем с кромки кавитатора 4. пограничном слое. Этому процессу также способствует попадание в пограничный слой дополнительного ко- 10 личества дер кавитации, вносимых подводимой жидкостью. Попадание в зону схлопьгоани большого количества пузырьков приводит к увеличению эрозионной активности кавитацй онного 15 пол. При этом прот женность активного кавитационного пол увеличиваетс в 2-3 раза, а интенсивность повьш1енй . эрозионной активности з ависит от количества жидкости, под- 20 веденной в пограничный слой на поверхности кавитатора 4. Количество подводимой в пограничный слой жидкости определ етс в процентах от расхода обрабатьгоаемой среды, сое- . 25 тавл ющим 78,9 м /ч. Эрозионную ак- тивность кавитационного пол оценивают по интенсивности кавитационного шума в зоне схлопывани пузырьков . .regulator 7). As a result of the supply of fluid to the boundary layer, its thickness and turbulence increase, which leads to an increase in the number of bubbles and their sizes in the boundary layer converging from the edge of the cavitator 4.. This process is also facilitated by the ingress into the boundary layer of additional amounts of cavitation introduced by the supplied liquid. A large number of bubbles entering the zone of collapse leads to an increase in the erosion activity of the cavitating 15th floor. At the same time, the extent of the active cavitation field increases by a factor of 2–3, and the intensity increases. erosion activity depends on the amount of liquid supplied to the boundary layer on the surface of the cavitator 4. The amount of liquid supplied to the boundary layer is determined as a percentage of the flow rate of the treated medium, soy. 25 plus 78.9 m / h. The erosion activity of the cavitation field is estimated by the intensity of cavitation noise in the bubble collapse zone. .

Как видно поньш1ение эрозионной активности кавитационного пол сос- 45 тавл ет 25-70%, а путем регулировани количества подводимой в пограничный слой ЖИДКОСТИ-,можно управл ть эрозионной активностью кавитационного пол .As can be seen, the erosion activity of the cavitation field is 25-70%, and by adjusting the amount of liquid supplied to the boundary layer, the erosion activity of the cavitation field can be controlled.
