Exhaust gas purification device

Abstract

The invention discloses a tail gas purification device and in particular discloses a tail gas purification device used in the field of chemical industry. The tail gas purification device has the advantages that energy can be saved, carbon black tail gas can be effectively purified, the purification process is safe and efficient, and the tail gas purification device is convenient to manufacture, mount, maintain and wash. The tail gas purification device comprises a bubbler and an absorption liquid container, wherein the bubbler comprises a tail gas inlet and a bubbling pipe; one end of the bubbling pipe is communicated with the tail gas inlet; the other end of the bubbling pipe extends into the absorption liquid container; the tail gas purification device also comprises a tail gas outlet; the tail gas outlet is communicated with the absorption liquid container; one end of the bubbling pipe is communicated with the tail gas inlet and the other end of the bubbling pipe extends into the absorption liquid container, so that the tail gas can enter the absorption liquid container by virtue of the bubbling pipe so as to be purified, and thus the tail gas leakage is effectively avoided; the tail gas outlet is communicated with the absorption liquid container, so that purified tail gas enters the next process by virtue of the tail gas outlet; a water seal cylinder is matched with a water seal tank to realize water sealing, so that the tail gas leakage can be effectively avoided.

Description

technical field [0001] The invention relates to a tail gas purification device, in particular to a tail gas purification device used in the chemical industry. Background technique [0002] Carbon black is a basic industrial raw material, widely used in tires and other rubber products, as well as fuel, printing, plastics, coatings and other industries. It is a highly dispersible black produced by incomplete combustion and cracking of coal tar and anthracene oil at high temperature. particle. The production of 1 ton of carbon black will produce 8,000--12,000 cubic meters of tail gas. The tail gas is a combustible gas with a calorific value of about 900 calories per cubic meter. The main components are water vapor, nitrogen, hydrogen, carbon monoxide, sulfur dioxide, hydrogen sulfide, and nitrogen oxides. things etc. Because this part of the exhaust gas has high temperature and contains corrosive gases, direct use will cause serious corrosion to equipment such as pipes and bo...

AI Technical Summary

Problems solved by technology

The disadvantages of this method are: it is difficult to realize automatic and continuous production, it occupies a large area, there is no standardization at all, and there is a risk of leakage

Therefore, in the prior art, there is no exhaust gas purification device that can save energy, and can effectively purify carbon black tail gas. The purification process is safe and efficient, and it is easy to manufacture, install, maintain and clean.
