Waste gas purifier

Abstract

The invention relates to a waste gas purifier which comprises a tank body, wherein an air inlet is formed in the lower end of the tank body, and an air outlet is formed in the upper end of the tank body. The waste gas purifier is characterized in that an annular water pipe is arranged under the inner wall of the tank body, and a high-speed mist spray nozzle is arranged on the annular water pipe; a hole is formed in the edge at the bottom end of the tank body, and a pipeline is arranged on the hole and leads to an oil-water separator; an air chamber is arranged at the middle segment of the inner wall of the tank body, and a breather pipe is arranged in the air chamber; a high-pressure electrostatic treatment system is arranged on the outer wall of the breather pipe, and a heat-superconducting pipe is arranged in the air chamber and communicated with a waste heat recoverer. According to the waste gas purifier, the high-pressure electrostatic treatment system is additionally provided, so that the effects of energy saving and emission reducing are obvious. The installing process of the waste gas purifier is more simple, scientific and reasonable than a waste gas purifier in the prior art. Through the adoption of the waste gas purifier, labor and time are saved, the production cost and manual cost are reduced, the benefits are more, the economic benefits of a production enterprise can be increased greatly, and the recycling effect of waste heat is good.

Description

Technical field: [0001] The invention relates to special equipment for environmental protection, in particular to an exhaust gas purifier. Background technique: [0002] In the past, the products on the market that solved the problem of exhaust gas emission in printing and dyeing enterprises were mainly water spray devices. The product structure is simple, the number of devices is large, the recovery of residual oil is small, the effect of pollution emission is not good, and the installation workload is large. The factory shutdown time is longer, and the loss to the factory is also great. The product we invented mainly solves the defects of the above products, changing from the original multi-component product to a single-component product, adding a waste heat recycling device and a high-voltage electrostatic treatment device, the effect of treating exhaust gas is better, and the recovery of residual oil is more (for the factory) It is also an income, 5,000 yuan / ton). In ad...
