Sewage sedimentation tank for waste incineration power plant

Abstract

The invention discloses a sewage sedimentation tank for a waste incineration power plant, belongs to the technical field of waste treatment, and solves the problems that an existing device cannot classify and screen impurities in a sedimentation tank, and the later screening cost is increased. The sewage sedimentation tank is technically characterized by comprising a tank body, a filtering cavityand a settling cavity are formed in the tank body, the upper part of the filtering cavity is provided with the settling cavity, the filtering cavity is communicated with the settling cavity, a settling assembly is arranged in the settling cavity, a filtering assembly is arranged in the filtering cavity, and a water injection port is fixedly formed in the upper surface of the tank body and communicated with the filtering cavity. A cleaning assembly is arranged; due to the arrangement of the cleaning assembly, impurities are cleaned, and the sewage filtering efficiency is improved. Meanwhile, due to the arranged setting assembly, sedimentation of the sewage is facilitated, the phenomenon that impurities are not cleaned thoroughly is avoided, an air pump is started to blow air into an aeration pipe, the air is released through an aeration spray head, accumulation of impurities on a second filter screen can be effectively avoided, and the filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a sewage settling tank for a garbage incineration power plant. Background technique [0002] As the scale of production continues to expand, a large amount of garbage will inevitably be produced. If these garbage cannot be effectively treated, it will take up a lot of space, and it is also a hidden danger for residents. Harmful substances in garbage will pollute the soil. , Harmful gases will also be released into the air, resulting in air pollution. At present, incineration is mainly used for garbage disposal. [0003] A large amount of sewage will be produced during the incineration process. If the sewage cannot be recycled in time, it will cause waste of water resources and pollute the environment. Chinese patent CN110314446A discloses a sewage settling tank for waste incineration power plants, including A sedimentation tank, the side of the sedimentation tank is fi...

Problems solved by technology

[0004] The purpose of the present invention is to provide a sewage settling tank for waste incineration power plants, including a pool body, the inside of the pool body is provided with a filter cavity and a settling cavity, the upper part of the filter cavity is provided with a settling cavity, the filter cavity and the settling cavity are connected, and the settling cavity There is a settling assembly in the cavity, and a filter assembly in the filter cavity. A water injection port is fixedly installed on the upper surface of the pool body. The water injection port communicates with the filter cavity. The right side wall of the body is also equipped with a vertical channel to solve the problem that the existing device cannot classify and screen the impurities in the sedimentation tank and increase the cost of later screening
