putting the collected kitchen garbage into a raw material collecting tank 1, adding a proper amount of water and acidolysis strains, starting a small motor I20, opening a stirrer 2 to break and uniformly mix the materials, opening a two-way valve 17 to put the materials onto a conveying belt in an anaerobic fermentation tank 3, opening a small motor II21, a small motor III25 and a small motor IV26 to drive a conveying belt 16 to slowly convey the materials to an overflow port 19 at a very slow speed and flow to the next layer, wherein the time from the falling of the materials into the conveying belt to the falling of the materials into a waste tank is about 2-3h, the materials are basically subjected to acidolysis before flowing into the last layer, the last layer of conveying belt is a filter layer and can filter acidolysis liquid, and residues are conveyed to the overflow port 19 along the conveying belt 16 and then flow into the waste tank 5 to reach a certain pressure and then are discharged through a one-way check valve 11. The prepared fermentation liquor is added through the yeast raw material adding port 15, the small-sized motor V22 at the lower part is turned on to drive the stirrer 14, the fermentation liquor and the acidolysis liquid flowing downwards from the upper part are fully mixed, so that methane is generated, the generated methane enters the methane storage tank 9 through the methane discharging port 4 at the top, and when the methane is used, the two-way valve 8 is turned on. The gas volume in the biogas storage tank can be observed by the pressure gauge 10, and the waste fermentation liquid is discharged into the waste barrel 27 through the liquid outlet 13 at the bottom.
The above description of the embodiments is only intended to facilitate the understanding of the method of the present invention and its core idea; for the person skilled in the art, the details of the embodiments, applications and materials may vary widely according to the spirit of the embodiments of the present invention, and the content of the present description should not be construed as limiting the present invention.
