According to the invention the task is to improve the quality of liquid mineralized organic adoptedthe fact, that organic substances contained in the composition of liquid fertilizer, mineralibus not less than 95% of organic substances in the waste prior to their digestion in the digester with the formation of humus.

The task in the implementation of the method is achieved by the fact that the first phase of anaerobic digestion liquefied and shredded organic waste substances in the outer chamber in an acidic environment at pH less than 7.0 is carried out until complete dissolution of all admissions in her pop-up and settling raznopolosnyh fermentation of organic waste substances active symbiosis splitting /gidroliznaya/ microorganisms with the destruction of their complex compounds into simpler and with the formation of fatty acids and skinny biogas carbon dioxide, hydrogen and hydrogen sulfide/entered then into the internal chamber run the second phase of anaerobic digestion in an alkaline medium at a pH over 7.2 with development of methanogenic them bacteria combustible biogas, which is produced in the inner chamber of the digester content in its composition to 95% methane with the caloric value of biogas to 33500 kJ/nm3up to 260 nm3from the tons of litter humidity of 70% and up to 110 nm3from the tons of pig faeces humidity 88%.

The achievement of the task execution device is achieved by the fact that attached in coolerserver digester concentric partition, separating the external and the internal chamber of the tank digester performed on the full height of the tank when joining it to the bottom with round or slotted holes in the wall with sloping down visors from an external camera, while the holes in the concentric partition is made in the lower half of its height from the bottom, and the bottom of the outer chamber are made pipe emptying her and closed with lids hatches clean the external camera from mineral precipitation.

The drawings schematically shows the device of the coaxial digester, in which figure 1 shows the overall look in the section with the attached to him pipelines, pressure reducing valves, injector and pump with heat exchanger, heater, piping, built-in tank digester nozzles, manholes and residuosity flows, and figure 2 is a view along a-a in figure 1.

Coaxial digester /1 and 2/ is a sealed /in this implementation cylindrical/ tank 1 with a conical bottom 2 and the dome cover 3 gotobaby.com 4, underneath which is attached to it reaching the bottom 2 of the tank 1 concentric partition 5, identical in shape in plan shape of the tank 1 in plan and separating tank 1 to 6 external and 7 internal chamber in which is placed the nozzles supplying liquefied waste 8 and features the who and the fermented mass 9. From the alternate tee on the end of pipe 8 is provided mixing of the incoming waste from fermentation in the outer chamber 6 of the mass of the jet pressure of the supplied liquefied waste from the tee pipe 8. Over 6 external and 7 internal cameras made pipes 10 and 11 allotment of them biogas, while the pipe 10 biogas collection from an external camera 6 digester is connected by a pipeline 12 with the suction inlet 13 of the injector 14, the pressure tube 15 which is connected to the heat exchanger 16 with the heater 17 and a pump 18. Suction pipe 19 of the pump 18 is connected to the pipe 20 fence fermented mass from the digester to the stirring and heating, while the outlet of the mixing chamber 21 of the injector 14 is connected to a pressure line 22 and the heated gas-liquid mixture with the introduction into the digester and installed above the bottom 2 rassredotochit stream 23.

To provide a wide range of regulation of specified quantities of excess biogas pressure and vacuum in the outer chamber 6 suction pipeline 12 injector 14 two distinct parallel lines 24 and 26 is connected to the pipeline 28. In the pipeline 24 is integrated pressure reducing valve 25 relieving excess pressure from the outer chamber 6 of the digester in the pipeline 28 biogas collection of inner chamber 7 and in the pipeline 26 is embedded ed is clanny valve 27 of the feed gas pipeline 28 in the outer chamber 6 of the digester in the formation of vacuum in it.

Execution tilted down visors 29 over the holes 30 in concentric partition 5 from the external camera 6 excludes entering the chamber 7 of the chamber 6 is deposited dense and trudnosvarivaemymi organic substances flowing into the chamber 6 in the composition introduced into it by the pipe 8 is liquefied and shredded organic waste digestion and prevents the flow generated in the chamber 7 of biogas into the chamber 6.

For periodic cleaning of the outer chamber 6 from mineral precipitation /soil, sand, clay, fine gravel, shell, etc./who on livestock and poultry farms come on digestion in a digester comprising liquefied and shredded organic waste in the lower part of the outer chamber 6 are closed by caps 31 hatches and pipe emptying 32.

Other pipelines to control the level of the fermentation mass and its overflow, sampling and other/as thermal insulation of the digester, installation of devices and sensors PILE is not shown, since their implementation is possible in many ways. In accordance with the requirements of SNiP pressure of the biogas in the inner chamber 7 of the digester is set in the range of 1.5-2.5 kPa.

Sequential phase anaerobic digestion liquefied and shredded organic waste from agriculture and municipal x the households in the proposed coaxial digester with the production of organic matter mineralized organic liquid fertilizer at the same time to produce high calorific biogas performed as follows.

Fresh liquefied and preferably crushed no bigger than its size is more than 5 mm of organic waste humidity 92±3% through the pipeline 8 is injected under pressure in the outer chamber 6, where the multi-directional jets from the tee pipe 8 flows enter the waste is mixed with contained in the chamber 6 fermentation by weight while crowding out through the overflow pipe bravenew the weight of the camera 7, which is mineralized liquid organic fertilizer. Download digester liquefied and shredded organic waste can be performed continuously continuously within daily dose download and periodically cycled one or more times per day with compliance with dose per day.

When loading the digester less dense organic matter emerge within the outer chamber 6 to the education of them in the acidic environment of the first phase of digestion of fatty acids and skinny biogas and more dense sedimentary organic matter down the camera 6, which is also in the acidic environment of the first phase of fermentation of them symbiosis splitting /gidroliznaya/ microorganisms are formed fatty acid and skinny biogas, which together with the products of decomposition surfaced low-density organic matter is introduced into the chamber 7 in the alkaline environment of the second phase of digestion: fatty acids from under the trump card is and 29 through the holes 80, and skinny biogas through the pipe 10, the pipeline 12 and the injector 14 in the composition of the gas-liquid mixture through residetial stream 23. Through holes 30 from the chamber 6 into the chamber 7 when loading chamber 6 fresh waste out of the socket 8 are also sredneplotnyh partially split organic matter who or Darussalam in the chamber 7, or remain nedorazumenij in the composition of the fermentation in the chamber 7 the mass discharged from the digester as a liquid mineralized fertilizers. In the composition introduced into the chamber 6 organic waste mineral inclusions /soil, sand, clay, fine gravel, shell, and others, which depend on methods animals and birds, settling to the bottom of the chamber 6 to form a precipitate with a small amount of non-biodegradable organic matter, which necessitates approximately every 3-4 years to produce through hatches 31 cleaning chamber 6 after discharge from her nipple 32 ferment it and partially in the chamber 7 pulp, leaving about 1/3 of the volume of the fermentation mass in the chamber 7 with an active population of methanogenic microorganisms. Save flushed from the chamber 6 fermentation mass is loaded again in the clean chamber 6 together with fresh liquefied and shredded organic waste that provides fast input operation of the digester in normal the operation.

A continuous supply of heated gas-liquid mixture from residuosity 23 at the bottom of the 2 cameras 7 provides it in the second phase of digestion at pH over 7.2 combined gas-liquid mixing of the fermentation mass when heated from flowing into the chamber 7 from the chamber 6 through the holes 30 more dense flow of acids and amino acids, Rostislava ascending dispersed heated gas-liquid flow fermented mass in the chamber 7, which provides for efficient growth and activation of populations of methanogenic bacteria with the production of their more biogas with a content of up to 95% methane with the caloric content of the biogas to 33500 kJ/nm3.

Depending on the installed operating modes of the digester due to humidity fermented mass, frequency and dose of loading wastes and their composition, temperature, digestion, and other factors, the pressure of the gas in the chamber 6 is changed, whereas the pressure produced in the chamber 7 biogas continuously and regulated by the gas tank or other devices within the established norms SNiP.

In case of emergency or any other forced to cease operation of the pump 18 to the injector 14, as well as in spontaneous abundant gas in the chamber 6, the pressure of the gas in the chamber 6 may exceed 2.0 kPa /200 mm of water. post/that will determine automatically srabatyvanie pressure reducing valve 25 and biogas from the chamber 6 will be in the pipeline 28 and further through the gas tank to the consumer.

When education in the vacuum chamber 6 more than 2.0 kPa automatically activated pressure reducing valve 27 and the gas pipeline 28 through the pipeline 26 will come into the chamber 6 and through the pipeline 12 will otkazyvatsa injector 14 with the formation of the gas-liquid mixture.

Maintaining a set temperature of the fermentation of organic matter in the digester, regardless of the temperature of the external environment in different periods of the year, automatically ensures that the pipeline entering the fermentation mass from the pump 18 to the heat exchanger 16 is installed /not shown/ temperature sensor interacting with a thermostat for automatic temperature control of the water heater 17, providing the necessary heating the fermentation mass in the heat exchanger 16 before it is input into the digester through the injector 14. The proposed method of anaerobic digestion liquefied and shredded organic waste can be carried out in the temperature range from 12° to 60°S, the optimal choice of which is determined by specific conditions.

The positive effect of using the present invention in agriculture is a full save without losses in the prepared liquid mineralized organic fertilizer from cutback and shredded organic waste of all nutrients for races the response before digestion in waste composition and fermentation translated in the most digestible plant forms with the formation of humus /humic and fulvic acids/ in the absence of a ready liquid fertilizer sludge organic matter.
