Waste gas desulfurization and denitrification device

Abstract

The invention relates to the technical field of waste gas desulfurization and denitrification equipment, in particular to a waste gas desulfurization and denitrification device. The device comprises asupporting underframe, and a desulfurization and denitrification tank body is mounted on the supporting underframe; a first bearing seat is arranged in the middle of the inner bottom face of the desulfurization and denitrification tank body, a second bearing seat is arranged on the upper part of the interior of the desulfurization and denitrification tank body, first horizontal connection rods are correspondingly arranged on the two sides of the second bearing seat, and the outer ends of the two horizontal connection rods are connected with the inner wall of the desulfurization and denitrication tank body; and a rotating barrel is mounted between the first bearing seat and the second bearing seat, the top of the rotating barrel is in a face sealed shape, and the bottom of the rotating barrel is in an opening shape. The device adopts an air jet barrel rotating in the forward direction and a sodium hydroxide spraying head disc rotating in the backward direction to form fierce collision,is convenient to use, can enable spraying liquid to react sufficiently with waste gas, accordingly sulfur and nitrate in the waste gas can be thoroughly removed, and thus the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of waste gas desulfurization and denitrification equipment, in particular to a waste gas desulfurization and denitrification device. Background technique [0002] With the continuous development of society, industry is also developing rapidly. However, when the equipment in rubber, chemical and other enterprises is working, waste gas containing sulfur and nitrate will be produced after combustion, and the waste gas will be discharged directly to the outside without desulfurization and denitrification, which will bring great damage to the environment. Traditionally, there are two methods for desulfurization and denitrification of exhaust gas. One is the wet method and the other is the dry method. Wet technology mostly uses sodium hydroxide solution as the spray liquid to remove sulfur and nitrate in the exhaust gas. However, in actual use, there are the following problems: when using a wet method to purify...

AI Technical Summary

Problems solved by technology

However, in actual use, there are the following problems: when using a wet method to purify the exhaust gas with sodium hydroxide solution, the "collision" between them is not complete, resulting in incomplete removal of the exhaust gas, so that the exhaust gas remains Sulfur, nitrate and other substances are harmful to the environment. The reason is that there is insufficient reaction between the two, which leads to incomplete removal of sulfur and nitrate in the exhaust gas.
