Description

Technical Field

[0001] This utility model relates to the field of anaerobic tank structure technology, and in particular to an anaerobic tank structure with an enamel-lined steel plate. Background Technology

[0002] An anaerobic digester is a closed reaction device designed specifically for large-scale biological treatment. Its core function is to create and maintain a strictly anaerobic environment. Under these conditions, a specific anaerobic microbial community efficiently degrades high-concentration organic waste, converting it into biogas, primarily methane, and significantly reducing sludge production. Enameled steel plates are the preferred choice for anaerobic digesters because they offer lifelong corrosion resistance, require no maintenance, and have a long lifespan.

[0003] Currently, the road transport of ultra-large tanks is restricted, and the on-site segmented manufacturing process is complex and time-consuming. Furthermore, the lack of automated slag-breaking equipment on the tank top leads to the long-term accumulation and hardening of the slag layer, forming an air barrier layer that blocks the rising channels of biogas, severely reducing biogas release efficiency.

[0004] Therefore, those skilled in the art have provided an anaerobic tank structure with an enamel-lined steel plate to solve the problems mentioned in the background art. Utility Model Content
