The invention relates to the field of purification of gases and can be used for exhaust gas cleaning in microbiological, paint, chemical, food, petrochemical industry, as well as in the processing of products and waste from agriculture and the connections of the input and output of the purified gas. Inside the housing in its upper part there are sprinklers. Under the sprinklers across the movement of gas was set perforated base. On the grounds posted by alternating layers of mixtures of natural organic porous material and fibrous material and organic porous material and granular material. On these layers placed a consortium of microorganisms (EN 2108380 C1, C 12 M 1/00, 10.04.1998).Also known installation for the biological treatment of gas, including bioabsorbable with fittings supply and exhaust air and the cleaned liquid, site irrigation, proceedings of the suspension of microorganisms, a circulation pump connected to the node of irrigation and collector of the suspension of microorganisms, proceedings of purified water, located in the lower part of the body under irrigation, and on the collection of the suspension of microorganisms consistently reinforced sheet of filter tubes for drainage of the filtrate (EN 2103344 C1 C 12 M 1/00, 27.01.1998). These pipes are connected with located in the lower part of the housing a collection of purified water. Site irrigation can be made in the form of Saharova wheel or manifold with injectors. Between the sheet filters can be set Packed leaves, and in the gaps between nasagot manifold with valve for periodic shutdown of the flow of filtrate.The closest analogue of the invention is the installation of biological treatment of gases, comprising bioabsorbable with fittings inlet and outlet gas and the culture fluid with internal elements for adsorption of microorganisms, and a collection of cultural liquid, connected to a pump and piping with fittings inlet and outlet of the culture fluid bioabsorbable with the formation of a closed circulation circuit of the latter (EN 2119950 C1, C 12 M 1/00, 10.10.1998).In the upper part of bioabsorbable posted by site irrigation, consisting of injectors. Internal elements are located in a vertical plane and each of them represents a supplementary sheet. Between them can be established dividing grid, preventing sticking of the sheets.A disadvantage of known systems is the lack of control over the cleaning process and its regulation, resulting in insufficient cleaning of gases.The technical result of the invention is to provide a control biological purification of gases and increase its effectiveness.This result is achieved by the fact that the proposed installation of biological treatment of gases, comprising adsorption of microorganisms, and the collection of cultural liquid, connected to a pump and piping with fittings inlet and outlet of the culture fluid bioabsorbable with the formation of a closed circulation circuit of the latter, equipped with a collection of a solution of salts with an agitator provided with a collection of cultural liquid.Bioabsorbable equipped with flow sensors and temperature of the purified gas, the control device of the content of impurities in the purified gases and consumption booster last, and the collection of cultural liquid sensor level, temperature and pH and placed in it a heat exchanger.The invention is illustrated by the drawing, which schematically shows the proposed installation.Installation of biological treatment gas includes bioabsorbable 1 with fittings 2 and 3, inlet and outlet gas inlet 4 and outlet 5 pipelines and internal elements 6 for adsorption of microorganisms, collection of 7 cultural liquid, connected to a pump 8 and the pipes 9 and 10 with the fittings 11 and 12 for supplying and discharging the culture fluid of bioabsorbable with the formation of a closed circulation circuit, and the collector 13 of the salt solution from the mixer 14, the fitting 15 to supply process water and lukeisha and temperature of the purified gas, and outlet lines 5 - unit 19 of the control of the impurity content in the treated gas and the pump 20 of the flow of the exhaust gases, for example, in the form of a fan.A collection of 7 the culture fluid is supplied by the sensors 21, 22, 23 level, temperature and pH and placed inside the heat exchanger 24, is connected to the mains hot and cold water (in the drawing not shown), the fittings 25 and 26 of the inlet and exhaust culture fluid, connected to the pipes 9, 10 closed circulation circuit, the fitting 27 for feeding a solution of salts of the collector 13 through the pipeline 28 and the drain fitting 29. Internal elements 6 bioabsorbable can be a horizontally positioned plates with a layer of bulk porous material (in the drawing not shown), or a vertical leaf filters and Packed leaves.The sensor unit are connected to the post monitoring, providing automatic control of the cleaning process (drawing not shown). Unit 19 of the control of the impurity content in the treated gas can be a chromatograph or a semiconductor gas sensor.The device operates as follows.
bornik serves a set of dry salt providing a salt solution, intended for the cultivation of microorganisms used for gas purification. Received saline solution through the nozzle 15 is served in a collection of 7 the culture fluid. Filing may be accomplished by gravity, if the collector 13 is located above the collector 7, or any known pump flow rate (in the drawing not shown). After filling saline collector 7 to a level controlled by the sensor 21, the flow of salt solution stop. Passing through the heat exchanger 24 hot water, heated saline solution in the collector 7 to the desired temperature. It is controlled by sensor 22. Sowing salt solution by microorganisms, which will later be used for biological purification of gases. Include pump 8 and serves the culture fluid of the collector 7 through the nozzle 11 in bioabsorbable 1. The culture liquid containing a microorganism culture and set of salts, flows through the internal elements 6 bioabsorbable 1, while the microorganisms adsorbed on their surface. At the same time from a collection of 13 serves salt solution to maintain the desired level of the culture liquid in the Assembly 7. Through fitting 12 culture fluid is amaut flow of saline solution from the collector 13 to the collector 7. The circulation of the culture liquid through bioabsorbable 1 continue up until its internal elements 6 will not accrue a sufficient number of microorganisms. The salt content in the culture fluid control sensor 23 pH compilation 7 and if necessary add a concentrated solution of salts of the collector 13. After building a sufficient number of microorganisms, the plant is ready for the cleaning process.Polluted air from process units through the fitting 2 is fed to bioabsorbable 1, with controlled flow and temperature of the cleaned gas through sensors 17 and 18. If necessary change through the pump 20, the flow of cleaned gases, as well as by known means changing their temperature. The cleaned gases pass through the inner elements 6 bioabsorbable 1 and through the nozzle 3 through the pipeline 5 is removed in the atmosphere. The device 19 when this control over the content of cleaned of impurities in the exhaust gases. The incomplete removal of cleaned of impurities by known means (reduced flow of the gas to be purified, the increase in the filing of the culture fluid, optimization of temperature bioabsorbable 1, and so on) carry out adjustment of the process depend on the type of cleaned gases, type remove impurities and extent of contamination.Installation can almost completely remove impurities from the exhaust gases of various industries. Installation of biological treatment of gases, comprising bioabsorbable with fittings inlet and outlet gas and the culture fluid, and internal elements for adsorption of microorganisms and the collection of cultural liquid, connected to a pump and piping with fittings inlet and outlet of the culture fluid bioabsorbable with the formation of a closed circulation circuit of the latter, characterized in that it is provided by the collection of a solution of salts with an agitator provided with a collection of cultural liquid, while bioabsorbable equipped with flow sensors and temperature of the purified gas, the control device of the content of impurities in the purified gases and consumption booster last, and the collection of cultural liquid sensor level, temperature and pH and placed in it a heat exchanger.
