Definitions

  • the invention concerns a process for controlling the com ⁇ posting air in a composting system for aerobic degrada ⁇ tion of organic material, a composting system for use in the performance of the process, and use of the composting system and the process to collect ammonia and to utilize the composting energy.
  • Composting is an aerobic biological process where micro ⁇ organisms degrade dry matter primarily to carbon dioxide, water and heat (about 17 MJ/kg of degraded dry matter). The degradation releases a considerable part of the ni- trogen content in the organic material as gaseous ammo ⁇ nia.
  • a high dry matter degradation rate it is possible to transform a large amount of organic material into compost in a short time and to obtain a considerable generation of heat and evaporation of ammonia.
  • microorganisms have favourable living conditions. It is generally known that aerobic microorganisms require a moist environment, supply of oxygen and removal of the composting products water, heat and carbon dioxide. The requirements with respect to the living conditions of the microorganisms involve a conflict between having a high content of water and oxygen at the same time.
  • the other essential prerequisite for a high degradation rate is a uniform and regular supply of oxygen to the or- ganic material during composting. This is ensured by com ⁇ posting in a composting reactor, which is a container with composting air control.
  • a composting reactor which is a container with composting air control.
  • the exit air from the composting reactor is about 60 °C, contains ammonia and is saturated with water vapour.
  • the possible content of water vapour in the composting air depends on the pressure and temperature of the air. Control of the pressure, temperature and oxygen-content of the composting air enables regulation of the dry mat ⁇ ter content in the organic material as well as the supply of oxygen during composting. The result of this regula ⁇ tion will be an extremely high degradation rate.
  • the energy in the composting air is primarily bound in water vapour, and condensation of the water vapour re- leases about 2.3 MJ/kg of condensed water vapour.
  • the wa ⁇ ter vapour in the composting air may be condensed by cooling and by compression. Use is made of the fact that the ability of saturated air to contain water vapour is halved by isobaric cooling of about 11 °C or by isother- mal compression which doubles the absolute pressure. It is generally known to use an air washer to cool air.
  • the air washer consists of a vertical pipe which is filled with a washing material. The washing material has a large surface and a low counterpressure for blowing of air.
  • the air washer operates according to the counterflow principle, as the washing water trickles down through the washing material and cools the air which is blown up through the washing material.
  • This type of air washer has previously been used in a composting system comprising a composting reactor to transfer energy from the exit air of the system to a heating system.
  • a heating system uses heat energy e.g. for space heating and hot service water.
  • Condensing at a high pressure is one of the basic prin- ciples of heat pump systems.
  • a heat pump is a circuit which consists of evaporator, compressor, condenser and throttle valve.
  • a working medium circulates in the cir ⁇ cuit and transfers energy from evaporator to condenser. This takes place as a consequence of a low pressure in the evaporator which causes the working medium to evapo ⁇ rate, following which the vapour is condensed, and the high pressure causes the working medium to condense in the condenser.
  • the heat pump principle is also used in DE Al 3 043 062, where the composting reactor is used as an evaporator, the composting air as a working medium, and where the condenser is incorporated in a heat exchanger.
  • the process heat collected via the heat exchanger, can be utilized for heating. Only the condensate is recycled to the composting mass.
  • This withdrawn air is cooled in an air washer by circulating the air through some air washer material where it meets some water, which is recirculated by a pump.
  • the heated water is collected in a sump, where the energy is conveyed via a heat exchanger to the consumer.
  • Fresh air is added by injecting it through the manure.
  • the object of the invention is to provide a process for controlling the composting air in a composting system of the type mentioned in the opening paragraph, which com ⁇ bines control of the composting process with collection of ammonia from the composting air and utilization of the composting heat, thereby obtaining an efficient process control which ensures a very high degradation rate which leads to a considerable generation of composting heat and evaporation of ammonia.
  • the composting heat and the ammonia are util- ized/collected in an extremely rational manner, as the utilization and the collection are integrated in the process control.
  • This efficient control ensures supply of oxygen for the composting and removal of precisely the amount of water vapour from the composting reactor which ensures a constant dry matter content in the organic material during composting.
  • the degradation of the dry matter in the organic material is compensated by removing a corresponding part of the water content in the organic material and the process water which is formed by the degradation of the dry matter.
  • the removal of the water from the organic material is closely linked with the utilization of the composting heat, as the composting heat is primarily used for evapo ⁇ ration of water in the reactor, which is given off again by condensation in the air washer.
  • the magnitude of the condensation in the air washer depends on the required state in the supply air of the reactor. Recirculation of the greater part of the composting air after the condensation minimizes the loss of energy from the air circuit, as the only direct loss is via the exit air from the heat pump circuit.
  • the air pump creates a positive pressure in the air washer, and it sucks composting air, including water va ⁇ pour, out of the composting reactor.
  • the suction creates a negative pressure which increases the possible content of water vapour and thus energy in the composting air.
  • the composting air is compressed from an absolute pressure of 0.5 to 0.99 bar, preferably 0.96 bar, in the reactor to an absolute pressure of 1.1 to 3 bars, preferably 1.3 to 2.2 bars in the air washer.
  • the energy consumption of the air pump increased with an increasing negative and positive pressure. This energy consumption is related to the advantages of the negative pressure in the reactor and the positive pressure in the air washer, respectively.
  • the composting air contains ammonia, and an excess of am ⁇ monia-containing washing water is currently formed be- cause of the condensation of the water vapour in the air washer.
  • the washing water consists of ammonia-containing condensed water vapour, and the excess of ammonia-containing washing water is withdrawn. Since the greater part of the ammonia in the composting air is either captured in the washing water or is recirculated to the composting reactor, the loss of ammonia from the circuit via the exit air of the circuit is limited.
  • the withdrawn composting air is passed through one or more serially connected containers containing composted organic mate ⁇ rial. This ensures that the withdrawn composting air is cleaned of ammonia, but also of other malodorous com- pounds, as the containers serve as biofilters.
  • the nutri ⁇ ent content of the composting air is hereby bound in the compost which is used as a soil conditiner.
  • the withdrawn com- posting air is used for stripping the ammonia from the ammonia-containing condensate in an ammonia washer, and then the air is passed through the biofilter consisting of one or more serially connected containers containing composted organic material.
  • This process leads to a re ⁇ duction in the content of ammonia in the condensate and an increase of nutrient in the compost.
  • stripping is made particularly ef ⁇ ficient by adding a base to the condensate before the am ⁇ monia washer, and all ammonia in the condensate is hereby transferred to the withdrawn composting air.
  • fresh air is passed through the ammonia washer before it is mixed with the recirculated composting air or is passed through the biofilter.
  • Fresh air does not contain ammonia and will therefore be extremely efficient to strip the ammonia from the condensate and then pass the ammonia back to the composting reactor or through the biofilter.
  • the fresh air is passed through the ammonia washer before the composting reactor, it is moreover ensured that the heat energy of the ammonia-containing condensate is transferred to the fresh air and is thereby recirculated to the composting reactor.
  • the invention moreover provides a composting system for use in the process of the invention.
  • the composting sys ⁇ tem is characterized in that it comprises a composting reactor, an air pump, an air washer, a throttle valve and a liquid circuit consisting of the air washer and a heat exchanger.
  • a particularly good effect is obtained when the invention is used in connection with a composting reactor for solid organic material which employs a vertical composting pro- file and counterflow aeration.
  • a composting reactor having a vertical composting profile fresh organic material is added from above, and compost is taken out at the bottom of the reactor.
  • the actual composting profile consists of fresh material at the top, an active zone in the centre and compost at the bottom. Thanks to the counterflow aeration, the air flow is directed oppositely to the movement of the organic material. This means that the relatively cool supply air is admitted at the bottom of the reactor, and the heated exit air is withdrawn at the top of the reactor.
  • This approach provides efficient aeration and utilization of the composting air, and it reduces the requirement with respect to the air performance of the air pump and thus reduces the energy consumption of the air pump.
  • the composting reactor with vertical composting profile and counterblow aeration is an insulated receptacle with gates at the ends, which comprises a plurality of seri ⁇ ally connected containers.
  • the composting reactor may moreover comprise several rows of serially connected containers which are stacked on top of each other, thereby providing a compact reactor with a minimum heat loss.
  • the individual containers consist of a closed receptacle having an opening in the bottom for admission of air and an opening at the top for withdrawal of air.
  • the sides of the containers have an inclination of 10 to 30°, prefer ⁇ ably 20°. This angle is to prevent formation of air chan- nels along the sides and thus disuniform aeration of the organic material.
  • Air is admitted to the individual container at the bottom and withdrawn from it at the top.
  • the air is passed through the rows of containers so that the supply air to the reactor is first passed through the containers with the oldest organic material and is withdrawn from the containers with the youngest organic material.
  • the vertical composting profile is divided into several layers corresponding to the number of containers in series connection.
  • the compression of the manure is reduced owing to the dead weight of the manure.
  • the dead weight of the manure presses the air out of the lowermost part of the manure layer. This increases the counterpressure in the manure, which causes composting air to flow in air channels along the sides of the reactor.
  • the structure moreover results in an increased thickness of the composting layer, and it is thus possible to ob ⁇ tain a particularly great temperature gradient in the or ⁇ ganic material, so that the temperature in the oldest or- ganic material is about 25 °C and the temperature in the youngest organic material is about 60 °C.

Abstract

Un procédé qui permet de moduler l'apport d'air de compostage dans une installation de compostage comprenant un réacteur de compostage aérobie (101), comporte plusieurs phases. Il consiste d'abord à aspirer l'air de compostage hors du réacteur de compostage (101) pour l'envoyer dans un laveur d'air (121) qui le refroidit avec l'eau de lavage. Une partie de l'air de compostage est éliminée et le reste subit un étranglement, est mélangé à de l'air extérieur puis est recyclé vers le réacteur de compostage (101). Cette modulation assure un taux de dégradation très élévé en agissant sur l'apport d'oxygène de compostage et sur la teneur en eau des matières organiques, ce qui produit une quantité considérable de chaleur de compostage et une très forte évaporation de gaz ammoniac. La chaleur de compostage parvient à un système de réchauffage par l'intermédiaire d'un échangeur de chaleur et un condensat contenant de l'ammoniaque est récupéré et utilisé pour amender les sols.
