Problems solved by technology

[0002] At present, the traditional biogas tank has the following shortcomings. When the biogas is sufficient, the feed liquid often flows out of the pool under high-pressure gas pressure, which must be exhausted in time to solve the problem. Harmful gases in the atmosphere
In addition, the existing biogas tank is prone to fouling

Embodiment Construction

[0009] The implementation of the present application will be further outlined in detail below in conjunction with the accompanying drawings.

[0010] Depend on figure 1 It can be seen that the present application is to install a one-way air outlet valve 2 on the air outlet pipe at the upper end of the biogas tank 1, the one-way air outlet valve 2 is connected to the safety exhaust valve 3, and leads to the air storage bag 5 through the water collector 4, and then uses the three-way 6 to communicate Stove 7, another outlet of tee 6 is circulated in the methane tank 1 again by circulation pump 8 gas.

[0011] The application installs a water collector 4 at the lowest part of the pipeline. When the stove is burning, the biogas is supplied to the stove. When it is not burning, the biogas is circulated into the biogas tank, which can promote the flow of the feed liquid, prevent crusting, and make the feed liquid evenly distributed. Enhance the contact between microorganisms and ra...

Abstract

The invention discloses a biogas storage and circulation device for a small biogas tank, which is characterized in that a biogas outlet pipe at the upper end of the biogas tank is provided with an unidirectional biogas outlet valve, a safety exhaust valve, a water collector, a biogas storage bag and a tee, one port of the tee is connected with a stove, the other port of the tee is connected with a circulating pump, and an outlet of the circulating pump is connected to the bottom of the biogas tank. The device has the advantages that when the large gas pressure exists in the tank, the biogas storage bag stores excessive liquid, the excessive liquid can not backfill towards the inside of the tank under the action of the unidirectional valve and can only be discharged from the safety exhaustin a small quantity when certain pressure is exceeded, and biogas in the biogas storage bag enters from the bottom of the tank through the circulating pump, thereby realizing the automatic stirring of the biogas, preventing raw materials from crusting, and forming the continuous good circulation of the biogas.

Description

technical field [0001] This application relates to a biogas tank utilization device, especially to a 10m 3 The following small biogas tank. Background technique [0002] At present, the traditional biogas tank has the following shortcomings. When the biogas is sufficient, the feed liquid often flows out of the pool under high-pressure gas pressure, which must be exhausted in time to solve the problem. Harmful gases in the atmosphere. In addition, the existing biogas tank is prone to fouling. Contents of the invention [0003] The purpose of this application is to overcome the shortcomings of existing small biogas tanks and provide a biogas circulation device with a simple structure. [0004] In order to achieve the above purpose, the technical solution adopted by this application is to install a one-way outlet valve, a safety exhaust valve, a water collector, an air storage bag and a tee on the gas outlet pipe at the upper end of the biogas tank, and one port of the tee...
