INVENTION
Russian Federation Patent RU2097421
BIOMETANOVAYA disposal plants
Name of the inventor: Viktor Tumchenok Ignatievich
The name of the patentee: Tumchenok Victor Ignatievich
Address for correspondence:
Starting date of the patent: 1994.06.30
Purpose: The invention relates to the utilization of manure and litter, cleaning selhozstokov, the use of crop residues, wood waste to produce biomethane and protein-vitamin supplement (BVD) and can be used at the enterprises of agroindustrial complex (AIC). The inventive camera methane fermentation is designed as a vertical housing with horizontal perforated partitions forming section enzymatic hydrolysis and on chamber axis mounted drive shaft with blades mounted thereon above the partition and the disk below the partition and forming with it the blowing section, communicating with the blowers when this section of the enzymatic hydrolysis for mash communicated with each other downcomers.
DESCRIPTION OF THE INVENTION
The invention relates to the utilization of manure, litter, cleaning selhozstokov, the use of crop residues, wood waste to produce biomethane and protein-vitamin supplement (BVD) and can be used at the enterprises of agroindustrial complex (AIC).
Known biometanovaya recovering apparatus comprising a collection of animal waste and poultry waste products, collection of plant residues, reported a dispersant substrate mixer and a heat exchanger for its heating and cameras sour, regression acidic, neutral alkaline, and methane fermentation, fitted with a stirrer and immobilization attachment (Viesturs C.E. et al. fermentation systems, Riga, 1986, pp. 18, 19), the lack of which is a low methane content in biogas, not exceeding 65 75% which lowers the efficiency of plant operation due to the oppression of activity of methanogens-kislotogenami anaerobic, acetogenic , atsetogidrogenami and so on in the chamber of methane fermentation.
The invention is aimed at increasing efficiency.

The drawing schematically shows biometanovaya recovering apparatus comprising a collection of 1 animal waste and poultry waste products, Collection 2 plant residues, reported a dispersant 3, a mixer 4 of the substrate and the heat exchanger 5 for its heating and cameras 6 acidic, 7 - Regression sour, 8 neutral, 9 alkali and 10 methane fermentation provided with mixing devices 11 and immobilization nozzle 12, the chamber 10 of the methane fermentation is designed as a vertical housing with horizontal perforated baffles 13 forming sections 14, enzymatic hydrolysis, wherein at the chamber 10 the methane fermentation axis mounted drive shaft 15, which above the perforated partition 13 mounted blade 16 and lower disc 17, forming a perforated partition 13, Blow section 18, communicating with the blower 19, and section 14 of enzymatic hydrolysis communicated with each other downcomers 20 and 21. In this case, the chamber 10 is communicated methane fermentation on mash with the microfilter 22 and the biomass of methanogens centrifugal disintegrator 23, and on poslebrozhevomu residue (PBO) microfilter 22 communicates with the aerobic chamber 24, similar in design to the camera 10, methane fermentation, and the camera 24 with the microfilter 25, heat exchanger 26, and a collection 27 protein and vitamin supplements. |
Biometanovaya recovering apparatus operates as follows.
Products of animal waste and poultry gidrosmyvom gidrosplavom and enter the collector 1 in which the stirring exempt from mineral inclusions. Collection of plant remains 2 received in the dispersant 3, in which they are ground impact shock to the hydrodynamic size comparable to the sizes of microorganisms. In the mixer 4, slurries are prepared with a substrate concentration of about 1% and 5 stand ratio between carbon, nitrogen, phosphorus in the range of 100: 5: 1. In the heat exchanger 5, the substrate is heated to a temperature of 36 38 o C and subsequently fermented in the chambers 6, 7, 8 and 9 with stirring device 11 in the presence of immobilization attachment 12, wherein nedobrod from chamber 9 alkaline fermentation moves into the chamber 8 neutral fermentation, in which for account ammonium hydroxide and ammonium bicarbonate reduces the acidity of the mash and increases the degree of collapse of the suspensions. Mash from the fermentation chamber 9 alkali into the upper section 14 of chamber 10 of the methane fermentation and biogas from fermentation chamber 9 alkali blower 19 is fed to the blowing section 18 into the chamber 10 from the bottom of the methane fermentation. The biogas is bubbled through the perforated baffle 13 and a layer of immobilization of the nozzle 12 and Section 14 of its enzymatic hydrolysis were taken supercharger 19 Blow to the next section, etc. Brew flows through downcomers 20 and 21 and with suspended old and dead cells it is taken up in methanogens microfilter 22, which in the field of inertial forces separates methanogens biomass. Biomass disintegrate in a centrifugal disintegrator 23 with the destruction of shells hydrodynamic cavitation and thermal effects. Enzymes fracture shells do not collapse and they are supplied together with the physiologically active substances (nucleic acids, vitamins, trace elements, etc.) in the upper section 14 of chamber 10 enzymatic hydrolysis methane fermentation. Enzymes disintegrant and young living cells methanogens decompose water into hydrogen and oxygen. Hydrogen reduction catalyst is carbon dioxide to methane, oxygen and biogas releases from impurities such as hydrogen sulfide. As a result biogas is converted to enzymatic hydrolysis with a concentration biomethane last 98 to 95% and a yield of 1.3 biomethane 1.5 kg / kg ashless organics. On balance poslebrozhevom (TSP) in the aerobic chamber 24 the biomass is grown by blowing into each section 18 Blow fresh air blowers 19. The biomass is separated in the microfilter 25, are sterilized in the heat exchanger 26 at a temperature of 90 o C and 95 from the collection of 27 protein-vitamin supplement ( BVD) is used at the rate of 1 g per 1 kg of live weight of livestock and poultry, which reduces the consumption of conventional feed for 20 to 30% increased egg laying, milk production, weight gain of meat by 30 to 40% improved genetics breeder, reduced loss of cubs, and BVD cost price ten times lower than the cost of hydrolysis fodder yeast. At the same time thanks to the installation biometanovoy going environmental improvement around the agricultural enterprises.
