Biogas generator

Abstract

A biogas generator includes a bathroom, a vacuum system and a fermentation system, the bathroom includes an infrared sensor arranged on a wall, a pedestal pan and an automatic cleaning device, the technical points are as follows: the fermentation system includes a feed tank, a fermentation tank, a discharge tank, a biogas bag, a waste material pond, a first extrusion device, a secondary extrusion device, a packer, a liquid storage tank, and an air cleaning unit arranged on the secondary extrusion device; the bottom of the fermentation tank is provided with a heater and a temperature sensor, the top of the fermentation tank is provided with an air pressure sensor, a mesh-like valve is arranged between the fermentation tank and the feed tank; a drying apparatus and a purifying controller are arranged between the biogas bag and the fermentation tank, a pneumatic valve III is arranged between the waste material pond and the discharge tank, the liquid storage tank is provided with one pair of liquid level sensors, the bottom of the liquid storage tank is provided with a discharge port, and a pneumatic valve IV is arranged on the discharge port. The biogas generator fundamentally solves the problems that in the prior art bathroom stool and urine are not conducive to treatment, a lot of organic matters are not fully used, and the like.

Description

technical field [0001] The invention belongs to a microbial fermentation device, in particular to a biogas generator, which is mainly suitable for the recovery and reuse of feces in public toilets. Background technique [0002] The biogas fermentation process has been widely used to treat various organic wastes, and obtain relatively clean biogas energy, and finally obtain organic fertilizers such as biogas residue and biogas slurry. Raw materials for biogas fermentation include crop straw, livestock and poultry farming waste, light industrial waste water and residue, domestic organic waste, sewage sludge, etc. In the traditional process, normal temperature fermentation (10~26oC) has been widely used due to its advantages of simple structure of fermentation tank, low input and high output. However, the fermentation process is often accompanied by a strong odor, and the biogas is almost impossible to recover. It can also cause serious accidents and is completely unsuitable f...
