INVENTION
Russian Federation Patent RU2089608
Bioreactor for HOTHOUSES
Name of the inventor: Viktor Tumchenok Ignatievich
The name of the patentee: Tumchenok Victor Ignatievich
Address for correspondence:
Starting date of the patent: 1995.03.24
Use: the utilization of manure and manure biogas for heating greenhouses, and bio-fertilizer for the soil substrate for foliar feeding of plants.
The inventive bioreactor comprises a body with a camera at the bottom of the fermentation and gas in the upper cavity, communicating with the plenum, which includes a floating bell, the lower edge of which is immersed in the hydraulic seal. With solid is placed outside the fermenter, and it between two concentrically positioned regenerative heat exchanger shells filled with packing, for example, steel wool, the bottom of which includes a gas combustion burner of biogas, and the upper part communicates with a greenhouse location. Solid fermenter fluid inlet manifold is provided at the top and effluent discharge pipe bottom.
DESCRIPTION OF THE INVENTION
The invention relates to the utilization of manure and manure biogas for heating greenhouses, and bio-fertilizer for the soil substrate for foliar feeding of plants.
Bioreactor is known, the outside of which is placed a solid phase digester in which the low efficiency of solid state fermentation and fermentation temperature control respectively, which reduces its performance [1]
Known bioreactor comprising a housing with a chamber fermentation at the bottom and a gas cavity in the top, communicating with the plenum comprising floating bell, the lower edge of which is immersed in the hydraulic seal in the form of two concentric shells, filled with water, a disadvantage which is high energy consumption for temperature control fermentation [2]
The purpose of the invention increase the efficiency of the bioreactor - is achieved in that concentrically to solid fermenter between the two shells situated regenerative heat exchanger, filled with packing, for example, steel wool at the bottom of which is placed the gas burner biogas combustion, and the upper part communicates with the room greenhouses and solid fermenter fluid inlet manifold is provided at the top and effluent discharge pipe at the bottom.
The processes proceed in a solid phase at a temperature fermenter 50-70 o C, which provides destruction of pathogenic flora litter or manure, a pretreated fermentation chamber. In order to increase the temperature of the compost in solid fermenter to remove weed seed germination concentrically placed him regenerative heat exchanger, a nozzle which is heated by combustion of biogas products. To eliminate the drying compost irrigate it from the reservoir, located in the upper part of the digester, and collect at the bottom of drains, which are used for foliar feeding of plants. The resulting biogas combustion products: carbon dioxide and water vapor in the atmosphere stabilize greenhouse and incubated process of fermentation of manure and litter.
The drawing shows a longitudinal sectional view of a bioreactor for greenhouses.
The bioreactor 1 comprises a housing 2 with a fermentation chamber at the bottom of the cavity 3 and the gas at the top, communicating with the plenum 4, which includes a floating bell 5 and the lower edge 6 of which is immersed in the hydraulic seal 7 in the form of two concentric shells 8 and 9. On the outer side of the bioreactor between shells 9 and 10 placed solid fermenter 11 and concentrically to it between the shells 10 and 12 is disposed a regenerative heat exchanger is filled with packing 13, for example, steel wool at the bottom of which is placed the gas burner 14 and the upper part 15 communicates with the room greenhouses and enzyme fermenter 11 is provided with a liquid supply manifold 16 at the top and runoff drainage pipe 17 at the bottom. The bell 5 is equipped with a pipe 18 for supplying liquid alkalizing and guide tube 19, moving in the guide sleeve 20 jib 21. The housing 1 is provided with nozzle 22 outlet drains from the chamber 2 fermentation. The bell 5 is a pipe outlet biogas 23 in a burner 14.
Bioreactor for HOTHOUSES WORKS AS FOLLOWS
Manure or litter, imported into the greenhouse, when retracted in the direction of the bell 5 is charged to the fermentation chamber 2. Fill the water hydraulic valve 7 and lowered him edge 6 Bell 5. Top loading irrigate through the pipe 18, lime milk, extract of wood ash or other alkalizing compound. The formed biogas is discharged through the pipe 23 and combusted in the burner 14 by heating the nozzle 13 of the regenerative heat exchanger with the combustion products is discharged through the upper part of the greenhouse space 15 by performing heating and increasing humidity. The liquid component of the fermentation chamber 2 is removed through the pipe 22 and is used for foliar feeding of plants. After 30-40 days 10 and shell 12 pushing the bell 5 and is withdrawn sideways after discharge of compost from solid phase digester shell 11 10 and 12 are brought together their half, and the solid residue poslebrozhevogo component is transferred from the chamber 2 in the solid phase digester 11 where there is its additional expansion for irrigation fluid from the reservoir 16, which allows to obtain a highly effective fertilizer and fertilizer out of the socket 17 for the plants.
CLAIM
Bioreactor for greenhouses, comprising a housing with a chamber fermentation at the bottom and a gas cavity in the top, communicating with the plenum comprising floating bell, the lower edge of which is immersed in the water seal in the form of two concentrically spaced shells filled with water and the outside situated solid fermenter characterized in that concentrically to solid fermenter between the two shells situated regenerative heat exchanger, filled with packing, for example, steel wool at the bottom of which is placed the gas burner burning biogas, the upper part communicates with the room greenhouses and solid fermenter provided with manifold supply fluid at the top of and effluent discharge pipe at the bottom.
