Abstract

The invention discloses a secondary fermentation biogas pressure regulator, a system and a method. Among them, the secondary fermentation biogas pressure regulator has a one-way flow function, which automatically prevents the biogas flow from flowing into the low-pressure membrane-enclosed biogas slurry tank. The secondary fermentation biogas pressure regulator includes: a pressure regulator body, the pressure regulator The main body of the regulator is in communication with the secondary fermentation air inlet pipe, the primary fermentation air inlet pipe and the air outlet pipe, respectively, and the main body of the pressure regulator is also in communication with the automatic water level control pipe, which is used to ensure the internal water level of the main body of the pressure regulator and The gas inside the closed regulator body is relatively independent from the atmospheric environment.

Description

technical field [0001] The invention belongs to the field of biogas pressure regulation, and in particular relates to a secondary fermentation biogas pressure regulator, system and method. Background technique [0002] The biogas slurry discharged from the biogas fermentation tank still contains a large amount of organic matter and methane bacteria inside, so it will still ferment to produce a certain amount of biogas. If this part of biogas is not collected and utilized, the emission of this greenhouse gas will inevitably pollute the air. Therefore, for large-scale biogas projects, projects with a large amount of biogas slurry will adopt a flexible membrane seal to collect and utilize the biogas generated by the biogas slurry to avoid environmental pollution. [0003] Due to the low gas storage pressure of the soft membrane, it needs to be adjusted when it is connected with the primary fermentation system and used together. The adjustment system is cumbersome and requires ...
