Automatic pressure discharge type biogas digester

Abstract

The invention discloses an automatic pressure discharge type biogas digester which comprises a pool body and a pool cover for sealing the pool body. A gas inlet and outlet is formed in the side wall of the pool body or the pool cover and is sealed by a set of parallel hinges. The two ends of each hinge are installed on the pool body or the pool cover in a rotating mode. An adjusting rod for adjusting the hinges to rotate is arranged on the biogas digester and is driven by a drive mechanism. A controller connected with the drive mechanism is arranged on the biogas digester. A gas pressure sensor is arranged in the pool body and connected with the controller. When the gas pressure, collected by the gas pressure sensor, in the biogas digester is larger than preset gas pressure, the controller controls the adjusting rod to rotate so as to drive the hinges to be opened. The biogas pressure in the pool body is collected through the gas pressure sensor, the drive mechanism is controlled by the controller to rotate so as to open the hinges so that biogas in the pool body can leak out, the gas pressure intensity in the pool body is automatically ensured, and the service life of the pool body is prolonged.

Description

technical field [0001] The invention relates to the technical field of biogas digesters, in particular to an automatic pressure-discharging biogas digester. Background technique [0002] Biogas can be used not only as energy for lighting, but also as gas energy for cooking. Since the main raw material for generating biogas comes from crops, it can greatly reduce the consumption of forest resources and coal-fired resources. Therefore, biogas is a popular energy-saving technology that has been popularized and applied in recent years and is widely used in rural areas. [0003] Existing biogas digesters use traditional building materials such as bricks, sand, lime, and cement. Although the method of building a biogas digester is relatively simple, the daily maintenance requirements after completion are very high, and there are many failures during use. For example, when the pressure of the biogas in the tank is greater than the preset air pressure, it will cause damage to the t...

[0003] Existing biogas digesters use traditional building materials such as bricks, sand, lime, and cement. Although the method of building a biogas digester is relatively simple, the daily maintenance requirements after completion are very high, and there are many failures during use.

For example, when the pressure of the biogas in the tank is greater than the preset pressure, it will cause damage to the tank and increase the maintenance cost
