Behind the thermogenic action of raw material through the Hybrid Heating pond, enter and carry out the anaerobically fermenting reaction in the one-level anaerobic reaction-pot, the biogas that produces enters in the collecting methane tank, and unreacted completely residue enter into the secondary anaerobic retort, proceed reaction, and the biogas that produces is sent in the collecting methane tank; In the time of reaction, the temperature of one-level anaerobic reaction-pot is higher than the temperature of secondary anaerobic retort, part changing food waste is broken off in the higher one-level anaerobic reaction-pot of temperature, part changing food waste is broken off in the lower secondary anaerobic retort of temperature, so relatively traditional single-stage retort, whole rate of decomposition effectively improves.
Further, be provided with cooling pool and water cooling pond between described one-level anaerobic reaction-pot and the secondary anaerobic retort, cooling pool and water cooling pond are interconnected, and the entrance of described cooling pool is communicated with the outlet of one-level anaerobic reaction-pot, and the outlet of cooling pool is communicated with the entrance of secondary anaerobic retort.Water cooling pond injects cooling pool with water coolant, and the residue that will pass through cools off, and reduces the temperature of residue, and then residue is sent into the secondary anaerobic retort.
Further, described cooling pool is provided with the hot water outlet, and this hot water outlet is positioned at the bottom of cooling pool.The water coolant of hot water outlet after with heat exchange drawn, and this drawing-off water can be used for other and need the place of hot water, such as heating bath, heating etc.
Further, the capacity of described one-level anaerobic reaction-pot is equal to or greater than the capacity of secondary anaerobic retort.The one-level anaerobic reaction-pot is main treatment tank, most changing food waste can be broken off in the one-level anaerobic reaction-pot, and the changing food waste of small portion just can be broken off in the secondary anaerobic retort, so the volume of one-level anaerobic reaction-pot is not less than the volume of secondary anaerobic retort.
Further, the utility model also comprises acidification pool, and described acidification pool is between Hybrid Heating pond and one-level anaerobic reaction-pot, and the entrance of acidification pool is communicated with the outlet in Hybrid Heating pond, and the outlet of acidification pool is communicated with the entrance of one-level anaerobic reaction-pot.Acidification pool can carry out preliminary treatment to changing food waste, for the reaction of the anaerobically fermenting of back provides reaction conditions.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model reacts to realize utilizing changing food waste to produce biogas by two-stage anaerobic, compares traditional single-stage anaerobic reaction, and the utility model divides changing food waste and solves more thoroughly, and in the situation of changing food waste equivalent, the biogas of generation is more.
(2) the utility model is by increasing cooling pool, heat during to the secondary anaerobic retort fully utilizes by the one-level anaerobic reaction-pot with changing food waste, and this heat changed into hot water by water coolant, this hot water can be used for other place, thereby indirectly reduced energy consumption, improved the utilization ratio of changing food waste.
