Acid gas emission treatment device

Abstract

The invention discloses an acid gas emission treatment device. A spiral gas guide slot is formed in the inner wall of a settling tank and is communicated with a gas inlet; the settling tank is internally provided with a plurality of flow baffle plates along the transverse direction; the upper end of the side wall of the settling tank is connected with a heat exchange box by means of a pipeline; the heat exchange box is internally provided with a spiral heat exchange pipe; a plurality of dust boards are evenly arranged at the bottom in the heat exchange box, and the upper ends of the dust boards incline to the gas inlet end of the heat exchange box; the side wall of the heat exchange box is connected with one end of a gas inlet pipe, and the other end of the gas inlet pipe extends into an alkali liquor box; a plurality of vent pipes are evenly arranged at the part, extending into the alkali liquor box, of the air inlet pipe; a cover body is arranged at the port of each vent pipe; a plurality of tapered gas outlets are evenly formed in the side wall of each cover body along the circumferential direction; a tail gas discharge hole is formed in the top of the heat exchange box. The acid gas emission treatment device can be used for removing particulate matters in acid gas and carrying out waste heat recovery; the acid gas emission treatment device enables the acid gas to be fully contacted with alkali liquor, thus increasing the absorption efficiency of acidic substances and solving the problems in the prior art.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and relates to an acid gas discharge treatment device. Background technique [0002] With the continuous development of society, more and more attention has been paid to environmental issues, but most factories have the problem of acid gas emission in the production and processing, and in the actual production, the acid gas carries particulate matter and the temperature is high, and the particulate matter has a great impact on the emission or treatment equipment. All have different degrees of damage, which reduces the service life of the equipment; high-temperature gas is directly discharged, polluting the environment; the existing acid gas treatment and discharge device has a low absorption rate of acid substances in the gas, and it is difficult to meet the discharge standard. Contents of the invention [0003] In order to achieve the above purpose, the present invention provides an ac...
