Electrical tar precipitator

Abstract

The invention provides an electrical tar precipitator. The electrical tar precipitator comprises a tar precipitator body, a power supply porcelain insulator box, a high-tension porcelain insulator, a high-voltage corona wire, a sealing assembly and a spray device, wherein the high-tension porcelain insulator is arranged in the power supply porcelain insulator box; the high-voltage corona wire is arranged in the tar precipitator and connected with the high-tension porcelain insulator; the power supply porcelain insulator box is arranged above the tar precipitator body; the sealing assembly is arranged below the high-tension porcelain insulator and used for preventing air in the tar precipitator body from entering the power supply porcelain insulator box; the spray device comprises a spray tube and a reservoir, wherein the reservoir stores liquid for cleaning the high-voltage corona wire; and the spray tube is used for communicating the reservoir with the upper part of the tar precipitator body. The electrical tar precipitator provided by the invention has the characteristics of capacity of continuously and stably running for a long time, long service life, convenience for maintenance, easiness for operation and the like.

Description

technical field [0001] The invention relates to a device for purifying impurities in gas, in particular to an electric tar catcher. Background technique [0002] In the existing technology, the electric tar catcher is responsible for the purification of coke oven gas and the removal of tar. It is the most widely used equipment in the coal chemical industry. It has the advantages of large processing capacity, high precision, and simple control. The operation quality of the electric tar catcher directly determines the important index of raw gas purification after treatment. [0003] figure 1 A schematic structural view of an electric tar catcher in the prior art is shown. Such as figure 1 As shown, the electric tar catcher 10 of the prior art includes an ammonia water spray pipe 11 , a high-voltage porcelain bottle 12 , a high-voltage corona wire 13 , a coke catcher tank 14 and a power supply porcelain bottle box 15 . The core of the electric tar catcher 10 comes from the ...

AI Technical Summary

Problems solved by technology

Therefore, the existing electric tar catcher has the disadvantages of unstable operation and low service life.

For example, the existing electric tar catcher often runs for 20 days and needs to be shut down for cleaning and maintenance
