About keeping fermented liquid temperature problem, the present invention adopts the fermentor tank tank body 11 of steel, heats and adopts outer adjoining pipe 28 modes, can avoid like this corrosion of fermented liquid to pipeline, long service life, and convenient for maintaining, reliable; Its two rigidity and intensity that can strengthen fermentor tank tank body 11, thus save fermentor tank tank body 11 with material, increase hardly cost.This fermentation tank body is as without additional outer adjoining pipe 28, and the thickness of fermentor tank tank body 11 need increase 2mm.
The water of heating of the present invention is supplied with by the water coolant of generator, and cooling tower is entered in water outlet, recycles.
About fermentor tank material, pass in and out problem: (1) fermentor tank charging, material is mixed and is sized mixing by the tank 52 of sizing mixing in proportion, after the separated part silts of sediment separator 3, by fresh feed pump 5 input fermentor tanks, has solved the problem of workshop dust; (2) fermented liquid discharging, many fermentor tanks of factory share 1-2 discharging pump (meaning not shown in the figures), in the time of should in workshop, total plain cloth is put, determine; Discharging is completed by discharging pump through cone end outlet 40; (3) methane outlet, methane outlet, at tank deck outlet 23, relies on the pressure of air pump, inputs ad hoc water-sealed tank 45 and arrives gas-holder through biogas output tube 54; (4) fermentation overflow port 27, overflow liquid refluxes into size-mixing tank 52.
Main working process of the present invention and principle are as follows:
Fermentor tank and air storage chamber are whole sealed vessels, and domestic refuse or organism enter factory and after deodorizing, screening, selection by winnowing, magnetic separation, fragmentation, enter size-mixing tank 52, in feeding-passage is sent into fermentor tank, and complete size-mixing tank passage and the overflow port 27 of closing to of charging; Fermentation starts.
Open the first recycle pump 6, the second recycle pump 7 and the 3rd recycle pump 8, make the first recycle pump 6, the input of the second recycle pump 7 and the 3rd recycle pump 8 is through the first recycle pump 6 input tubes 18, the second recycle pump input tube 20, the 3rd recycle pump input tube 22 inputs, output is through the second recycle pump output tube 19, the 3rd recycle pump output tube 21 is by 34 one-tenth circulation passages of the first inner ring type pipe 32 second inner ring type pipe 33 the 3rd inner ring type pipes, on the first inner ring type pipe 32 second inner ring type pipe 33 the 3rd inner ring type pipes 34, be equipped with jet orifice 16, jet orifice 16 is to certain angle hydrojet, make fraction in tank utilize tangent line output and tangent line input fluid inertia to produce rotation, its ejection liquid forces the flow direction tank skin in tank centre, reaches tank center mixed with nearly tank skin place liquid, the eddy current producing while rotating due to fraction in tank during the fermentation, make a small amount of inorganics be deposited in bottom because proportion is greater than organism, in order to prevent that pot bottom from hardening, the output of the first recycle pump 6 through 17 of first ring pump mains enter the 4th inner ring type pipe 38 by tank at the bottom of jet orifice 42 at the bottom of tank, spray, by sediment blow off cone the end 39, another output enters fluidic module 30 through sediment separator 3 is laggard.
Meanwhile, suspended substance in fermenting process in fermented liquid, because biogas rises, impel suspended substance to form " wine with dregs lid " in liquid level cohesion, be unfavorable for fermentation, in the design, adopt fluidic module 30, and first ring pump output liquid enters fluidic module 30, its ejection liquid forces the flow direction tank skin in tank centre, and the input of all recycle pumps is all from outlet 40 outputs at the bottom of fermentor tank tank body 11 bottom cones, during operation, in fluidic module 30 generation negative pressure suitable for reading, wine with dregs lid is constantly sucked and pushes to fermentor tank middle part.
Open biogas reflux pump 46, by biogas backflow sparge ring 35, make to produce biogas and move upward fast and drive liquid to move upward, by with upper type to meet the requirement of homogeneous soaking.Reach the object of Water-gas linkage.Fermentor tank
The second recycle pump 7 of tank body outside, the 3rd recycle pump 8, fresh feed pump 5 and 9 work of seed transferpump are all step; And the first recycle pump 6 needs uninterrupted duty because completing silt separation.Separated silt is transported to production of construction materials workshop through silt discharge manifold 47.
In tank, raw material produces biogas and rises to tank body top, and when every square metre of biogas pressure is greater than 0.2 kilogram, methane outlet valve is opened automatically, and now high-pressure pump can be inputted biogas pressurization in high pressure tank for generator by water seal.
After having fermented, in tank, humic acids (natural pond slag) is transported to composting Workshop Production fertilizer by discharging pump (meaning not shown in the figures) from outlet at bottom after High Temperature Sterilization after discharge header pipe 48 is delivered to belt filter press dehydration.
This fermentation unit, owing to being hermetic, regulates temperature according to the requirement of fermentation, regularly adds special bacteria, has fermentation period short, and fermentation is thorough, the advantage that factor of created gase is high.Compare with traditional fermentation unit, there is the advantage of low, the easy installation of cost of manufacture, energy efficient 2/3rds raising factor of created gases 35%.
Finally it should be noted that, the foregoing is only preferred embodiment of the present invention, rather than the restriction to technical solution of the present invention, any being equal to that the technology of the present invention feature is done, replaces or corresponding improvement, still within protection scope of the present invention.
