Self-cleaning device for industrial wastewater

Abstract

The invention discloses a self-cleaning device for industrial wastewater. The self-cleaning device comprises a base plate, a first neutralizing tank, a second neutralizing tank, stirring mechanisms and a chemical applying mechanism, wherein the first neutralizing tank and the second neutralizing tank are fixedly mounted on the top surface of the base plate, and the first neutralizing tank and the second neutralizing tank are provided with the stirring mechanisms. The device is ingenious in structure; the chemical application mechanism can apply chemicals into the first neutralization tank and the second neutralization tank at the same time; when acidic substances in wastewater are to be cleaned, the flow of the wastewater does not need to be cut off, and only the flow speed of the wastewater needs to be controlled, so continuous cleaning of the wastewater is facilitated, and the treatment capacity of the wastewater between units is conveniently improved; and the device adopts the first neutralization tank and the second neutralization tank to neutralize the wastewater twice, and adopts the overflow principle to discharge the wastewater in the first neutralization tank and the second neutralization tank, so the time of retention of the wastewater in the first neutralization tank and the second neutralization tank can be prolonged, neutralization reactions can be carried out thoroughly, and the acidic substances in the wastewater can be cleaned conveniently.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater cleaning devices, in particular to a self-cleaning device for industrial wastewater. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process that are lost with water. There are many kinds of wastewater with complex components, and the wastewater contains acidic substances. In order to avoid environmental pollution, it needs to be neutralized before it can be discharged; [0003] The existing patent (notification number: CN105600978B) discloses a cleaning device suitable for acidic industrial wastewater, which relates to the field of acidic industrial wastewater treatment. A cleaning device suitable ...

AI Technical Summary

Problems solved by technology

In the process of realizing the solution, the inventor found that the following problems in the prior art have not been well resolved: 1. The operation of the device is relatively troublesome. When cleaning the acidic substances in the waste water, the waste water needs to be stored and put into a In the tank, the neutralization reaction is carried out. At this time, the wastewater is in a state of being static and unable to flow, and the amount of wastewater treated per unit time is small, so the flowing wastewater cannot be continuously treated; 2. Because after the treatment of acidic wastewater, the neutralization As a result, the waste water should be neutral or weakly alkaline. The device only adds liquid medicine once to the waste water. The acidic substances in the waste water are not easy to be removed, and it is not convenient to ensure the quality of the waste water after cleaning. There are certain deficiencies.
