Closing-sunning type solar energy methane tank

Abstract

The invention discloses a solar biogas generating pit. A feeding tank and a discharge tank communicating with each other are arranged on the two side of a fermenting tank. The upper end of the fermenting tank is covered with a transparent vault, a tracheal tube runs through the middle of the vault and communicates with the interior of the fermenting tank; a biogas storage device is arranged at one side of the discharge tank; a gas transmission pipe communicating with the tracheal tube is divided into two branches, and one end of the branch of the gas transmission pipe is connected to the biogas storage device. The biogas generating pit has the advantages that the solar heat can be collected more efficiently; proper temperature can be preserved in the fermenting tank in winter; the biogas output is high; and the biogas generating pit is safe to use and easy to collect biogas.

Description

technical field

[0001] The invention relates to a device for generating biogas, in particular to a biogas pond. Background technique

[0002] The biogas digester has been widely used as a device for generating biogas by using waste liquid (people, feces, crop stalks, waste water, etc.). The main structure of an existing biogas digester is that the fermentation tank is connected to the feed tank and the discharge tank respectively provided on both sides, the upper end of the fermentation tank is covered with an opaque vault, and an air guide tube is connected to the top of the vault. The middle part communicates with the interior of the fermentation tank. This kind of biogas digester has the following disadvantages: the biogas produced in use is stored in the fermentation tank, and there are both waste liquid and biogas in the fermentation tank. When there is too much biogas in the fermentation tank and it is not used in time, the fermentation tank The pressure is high, whi...
