Description

Technical Field

[0001] The utility model belongs to the technical field of anaerobic fermentation, in particular to a tower-type high-temperature anaerobic fermentation gas making device. Background Art

[0002] Tower high-temperature anaerobic fermentation gas production is a technology and equipment that produces gas by treating organic waste through microbial activity in an anaerobic environment. It can also be called anaerobic digestion process.

[0003] High-temperature anaerobic fermentation gas production mainly relies on appropriate microorganisms or organisms, such as anaerobic bacteria and anaerobic archaea, which use organic matter for metabolic activities in an oxygen-deficient environment to produce gases such as methane. High-temperature anaerobic fermentation has specific advantages, such as the relatively high metabolic rate of anaerobic bacteria, organic matter removal and killing rate of pathogenic bacteria under high temperature conditions. In the existing tower-type high-temperature anaerobic fermentation gas production technology, the organic waste to be fermented is placed in a fermentation tank and heated at the same time to allow anaerobic bacteria to carry out metabolic activities and decompose organic matter to produce gas. The liquid is discharged through the drainage pipe, the gas is discharged through the exhaust pipe, and the waste residue is discharged through the residue discharge port. When used for a long time, the drainage pipe may be blocked, affecting the efficiency of drainage. At this time, the drainage pipe needs to be cleaned. To clean the drainage pipe, the drainage pipe needs to be removed, and the steps are relatively cumbersome.

[0004] To this end, the utility model provides a tower-type high-temperature anaerobic fermentation gas production device. Utility Model Content
