Description

Technical Field

[0001] The utility model relates to the technical field of buffer tanks, in particular to a black water buffer tank. Background Art

[0002] Industrial black water refers to wastewater generated during industrial production. Industrial black water usually contains a large amount of pollutants and harmful substances. If it is discharged directly without treatment, it will cause serious pollution to the environment. Therefore, the treatment and disposal of industrial black water is one of the important tasks of environmental protection. When industrial black water is being treated, it is usually necessary to use a buffer tank to buffer the pressure fluctuations of the black water to improve the economy and safety of black water operations.

[0003] Since industrial black water is highly corrosive and abrasive, the water inlet pipe above enters the buffer tank. Due to the pressure of the black water, after a long period of flushing, it is easy to cause wear on the inner wall of the tank, thereby reducing the service life of the buffer tank body. The corrosiveness and abrasiveness of the buffer tank body are relatively insufficient. At the same time, the buffer tank is operated under negative pressure as a whole, and there are high requirements for the reliability of the seal. The sealing and leak-proof performance is relatively insufficient. For this reason, we propose a black water buffer tank to solve the above problems. Utility Model Content
