Methane pressure stabilizing device and manufacturing process thereof

Abstract

The invention belongs to the technical field of renewable energy sources, and in particular relates to a methane pressure stabilizing device and a manufacturing process thereof. The methane pressure stabilizing device is characterized by utilizing a principle of separate storage in two pools, i.e. one material fermentation device and a methane storage and pressure stabilizing device are constructed; when methane in the pools is generated continuously and the pressure of the pool bodies is increased, the methane continuously flows to a methane storage tank (2) through a methane guide pipe (8); the more the methane is generated, the higher the pressure of the methane storage tank (2) becomes; when the methane stored in the methane storage tank (2) is too much or the amount of the methane used by farmers is too small, excessive methane is drained through a pressure relief valve (3), and the pressure of the methane supplied to the farmers is unchanged; and a one-way valve (6) is installed on the methane guide pipe (8), when the methane generation amount of a fermentation pool (7) is less, the one-way valve (6) can ensure the pressure in the methane storage tank (2) and prevent methane in the methane storage tank (2) from flowing back to the fermentation pool (7), and the pressure of the methane supplied to the farmers is unchanged.

Description

technical field

[0001] The invention relates to a device for preparing biogas by anaerobic fermentation of organic waste, belonging to the technical field of renewable energy, in particular to a biogas voltage stabilizing device and a manufacturing process. technical background

[0002] As a high-quality renewable energy that can be widely developed and utilized in rural areas, biogas is an inevitable trend in the development of rural energy in the future, and it is one of the essential contents of the construction of a new socialist countryside. At present, among the biogas digesters commonly used in rural areas of our country, user-type biogas digesters are the main ones. The role of biogas digesters in rural areas is that on the one hand, biogas digesters can process organic waste to generate bioenergy, and on the other hand, they can ferment manure produced by animal husbandry. Organic fertilizers can also incorporate pollutants that affect the rural environment into bio...
