Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to an anti-crusting device for enamel fermentation tanks. Background Technology

[0002] In wastewater treatment, enamel-lined fermentation tanks are used for collecting biogas produced during the anaerobic digestion and fermentation of organic matter in wastewater. Over prolonged use, these tanks are prone to sludge buildup, with crusting forming inside or at the bottom. This reduces the effective volume of the tank, causing abnormal microbial growth, affecting fermentation efficiency, and potentially leading to localized corrosion, damaging the enamel coating, and shortening the equipment's lifespan. Current cleaning procedures for enamel-lined fermentation tanks involve stopping the tank, emptying the contents, and transferring the wastewater to another storage tank. The tank is then manually or robotically rinsed to thoroughly remove dirt from the inner and bottom walls. After cleaning, the liquid is recycled.

[0003] However, the existing cleaning process for enamel-lined fermentation tanks interrupts wastewater treatment and stops operation within the tank, leading to reduced overall treatment efficiency and increased discharge burden. Furthermore, the discharge of wastewater requires additional storage tanks, adding another tank cleaning step, and the multiple transfers and recirculation processes increase time costs. Therefore, we propose an anti-crusting device for enamel-lined fermentation tanks to address these issues. Utility Model Content
