Methane producer

Abstract

A biogas generating device is disclosed, which aims to solve solve two technical problems of severe layered in biogas material and hardness to clear residue and discharge material, and realize constant temperature fermentation of biogas digester. Hollow shaft gets through anaerobic fermentor, and is fixed to housing at two terminals of the anaerobic fermentor by shaft bearings. A helical vane is arranged on hollow shaft inside the anaerobic fermentor, with intervals left inside. Separating house which do not communicates with each other are disposed at two terminals inside the hollow shaft. The first separating house communicates with interval of helical vane through hot water inlet opened on hollow shaft, the second separating house communicates with interval of helical vane through hot water outlet opened on hollow shaft. The hollow shaft is driven to rotate by a driving mechanism.

Description

a biogas generator technical field The invention relates to a biogas generator. Background technique Biogas is a high-quality, high-efficiency, green and environmentally friendly fuel, and has a very broad prospect of replacing traditional energy sources. However, due to the static fermentation process used in the biogas digester type, there are "microbe-poor areas", "fermentation blind areas" and "feed-liquid short circuits" in the fermentation room. After the rural household hydraulic biogas digesters have been in operation for a period of time, due to the different specific gravity and natural sedimentation of the raw materials in the digester, the fermenter is gradually divided into sediment layer, active layer, clear liquid layer and scum layer from bottom to top, resulting in the "consolidation" of the biogas digester. shell" problem. Incrustation has become a prominent problem in the current rural hydraulic biogas digesters. Years of inspections have proved that ...

Problems solved by technology

The rotation of the hollow shaft 3 of the present invention drives the spiral blade 2 to rotate, hot water flows through the gap of the spiral blade 2, and simultaneously completes the dual functions of stirring and heat exchange. When the spiral blade 2 rotates, its function is equivalent to a multi-phase mixing The pump can discharge the biomass residue from the anaerobic fermenter, which solves the problem of serious stratification of the biogas raw material in the biogas generator and the difficulty of removing the residue and discharging, and realizes the constant temperature fermentation of the biogas tank
