Multilayer continuous cavitation impinging stream reactor

Abstract

The invention discloses a multilayer continuous cavitation impinging stream reactor, which solves the problem of low mixing efficiency of a catalyst and sewage in the sewage treatment process, and is characterized in that a reaction bin is internally provided with a plurality of reaction discs which are sequentially distributed from top to bottom, and each reaction disc is provided with an upper cover plate and a lower cover plate; an air guide bin is reserved between the upper cover plate and the lower cover plate, the air guide pipe is communicated with the air guide bin in each reaction disc, the upper cover plate is provided with an exhaust hole communicated with the air guide bin, a plurality of nozzles are arranged on the sides, close to each other, of every two adjacent reaction discs, and the nozzles are communicated with the outer parts of the reaction discs. A liquid spraying pipe communicated with the nozzle is arranged in the gas guide bin, the liquid guide pipe penetrates through each reaction disc and is communicated with the liquid spraying pipe in each reaction disc, an overflow pipe penetrating through each reaction disc is arranged in the reaction bin, and an overflow hole is formed in the position, between every two adjacent reaction discs, of the overflow pipe. And the purpose of efficient sewage treatment is achieved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a multi-layer continuous cavitation impingement flow reactor. Background technique [0002] In recent years, many industrial enterprises have developed rapidly, but they have not paid attention to the pollution problem. The chemical industry is seriously polluted, and the industrial wastewater pollution is getting worse. According to statistics, there are more than 100,000 kinds of synthetic organic compounds in as many as 7 million kinds of organic compounds, and the number of organic compounds is increasing year by year at a rate of at least 2,000 kinds. Over 80% of the rivers in my country are polluted, 70.6% of the length of the rivers are polluted, and more than 90% of the rivers are polluted. % of urban water sources are polluted. Industrial wastewater from petrochemical, paper, pharmaceutical and other factories is one of the main sources of organic pollutants in ...

AI Technical Summary

Problems solved by technology

[0003] In this kind of sewage treatment, chemicals and catalysts are usually added to the sewage to neutralize the chemicals and pollutants in the sewage. After adding chemicals and catalysts, the existing sewage is usually mixed by cavitation impingement flow. In order to accelerate the reaction speed of the chemical agent and the compound in the sewage, however, most of the existing cavitation impingement flow reactors use a single set of colliding nozzles for colliding and mixing, resulting in low sewage treatment efficiency
