Abstract

The invention relates to odor dissipation prevention equipment, and discloses a water seal odor-resistant cover plate. The cover plate comprises a cover plate pre-buried frame pre-buried above an access hole, and is characterized in that water retaining walls are arranged around the cover plate pre-buried frame, a water seal groove is formed between the water retaining walls and the peripheral side walls of the cover plate pre-buried frame, and a cover plate is arranged above the cover plate pre-buried frame; water is injected into the water seal groove to form a water seal, and the water sealcompletely covers a gap between the cover plate and the access hole; and the water seal groove is connected with an automatic water supplementing device, and automatic water supplementing of the water seal groove is achieved through the automatic water supplementing device. According to the technical scheme, the structure is simple, work is reliable, and odor in a sewage pool is prevented from diffusing through the automatic water supplementing device. Meanwhile, according to the technical scheme, sliding and displacement of the cover plate can be limited, and personnel falling accidents andodor dissipation are avoided.

Description

technical field [0001] The invention relates to an anti-odor gas dissipation device, in particular to a water-seal anti-odor cover plate. Background technique [0002] With the rapid development of my country's economy and urbanization, the sewage generated in cities has increased sharply, and sewage treatment has become an inseparable part of cities. At this stage, harmful odor will escape into the air through the gaps between the cover plate and the inspection hole, affecting the air quality and endangering the health of the plant personnel and nearby residents. On the other hand, safety accidents caused by the sliding and shifting of the cover plate causing people to fall into the pool by accident happen from time to time. Contents of the invention [0003] The present invention aims at the disadvantages in the prior art that the odor in the sewage pool is easy to volatilize into the air, there are many cover plates and the maintenance workload is heavy, and personnel ...
