Abstract

The invention belongs to the technical field of biogas production, and discloses a method and equipment for producing biogas through anaerobic fermentation of biomass. The equipment includes a fermentation tank; a screw feeding device and a gas-liquid separator are installed on the top of the fermentation tank, and a dehydration discharging device is installed at the bottom; a heating material-guiding base and a multi-angle agitator are successively installed inside the fermentation tank from bottom to top; the top of the multi-angle agitator is successively connected to a decelerator and an agitator motor; and the decelerator and the agitator motor are fixed between the screw feeding device and the gas-liquid separator on the top of the fermentation tank. Thus, based on the arrangement ofthe multi-angle agitator, continuous stirring without dead angles can be carried out during overall anaerobic fermentation, so that raw materials in the fermentation tank can be fully mixed, and phenomenon such as sediment and scum during fermentation can be effectively avoided; and therefore, the conversion efficiency of biogas and the stability of the overall operation of the equipment can be enhanced, and the problems of equipment blocking can be avoided as well.

Description

technical field [0001] The invention belongs to the technical field of biogas production, and in particular relates to a method and equipment for producing biogas by anaerobic fermentation of biomass. Background technique [0002] In the prior art, using biomass raw materials as the main fermentation raw material to produce biogas is an effective way to produce biogas. At present, the processing methods for fermentation of biomass raw materials mainly include wet anaerobic fermentation and dry anaerobic fermentation. No matter what form of anaerobic fermentation is adopted, in order to improve the fermentation efficiency, stirring operation is required during the fermentation process. [0003] However, the existing equipment generally adopts the method of side push stirring or top stirring, which tends to have a stirring dead zone, and it is difficult to improve the problem of scum and sediment during the fermentation process. Contents of the invention [0004] In view of...
