Air purifying sprayer and air purifying spraying system

Abstract

The invention discloses an air purifying sprayer. The air purifying sprayer has the advantages that the design is reasonable, and the structure is simple; by arranging an N-shaped separating plate andan inverted N-shaped separating plate, a spraying liquid in a liquid guide pipe smoothly flows, and an eddy chamber formed by step holes is utilized, so that the blockage and deflection of the spraying liquid can be effectively prevented, and a washing liquid is uniformly sprayed. The invention discloses an air purifying spraying system. The air purifying spraying system has the advantages that by arranging a plurality of groups of air purifying sprayers in a step height way, the spraying and washing effect is obviously improved; an inclined blocking plate and fine through holes in the inclined blocking plate are effectively matched with the spraying effect of the air purifying sprayers, so as to reduce the residual fine solid impurities and acid gas in the tail gas, and enable the tail gas treated by the tower to reach the national emission standard; finally, an anti-corrosive and heat-resistant separating layer is arranged at the whole inner wall of a spraying tank, so as to effectively prevent the spraying tank from being corroded by the acid gas or acid solution, and obviously prolong the service life of the air purifying spraying system.

Description

technical field [0001] The invention relates to the technical field of tail gas purification, in particular to a gas purification spray system and a gas purification spray system. Background technique [0002] With the strengthening of environmental protection awareness, factories pay more and more attention to the treatment of exhaust gas and dust emitted during production. At present, for the removal of harmful substances in flue gas or other industrial exhaust, the method of spraying and washing in the absorption equipment is mostly adopted, that is, a large amount of washing liquid is used to spray the exhaust smoke to make the harmful substances and dust particles in the exhaust smoke Enter the scrubbing liquid and separate from the gas, so as to realize the purification of tail gas. However, in order to improve the quality of exhaust gas purification, a large amount of washing liquid is often required to be atomized under high pressure to continuously spray the exhaus...

AI Technical Summary

Problems solved by technology

However, in order to improve the quality of exhaust gas purification, a large amount of washing liquid is often required to be atomized under high pressure to continuously spray the exhaust gas. The existing spray structure is generally composed of multiple spray pipes on the same plane. The bottom of the pipe is provided with dense spray holes at intervals. This structure not only has a high damage rate and is difficult to repair, but also if there is leakage in one spray hole during use, the spray liquid in the spray pipe will basically flow from the spray hole. The spray hole flows down, which greatly weakens the spray function

In addition, when the existing spiral nozzle sprayer washes the exhaust gas such as phosphoric acid tail gas and synthetic ammonia desulfurization, the high content of impurities often leads to blockage of the spray hole, partial flow, and uneven spraying of the washing liquid, which seriously affects the washing effect; During the process of exhaust gas, since the spray tower is often made of steel, the acid gas will cause serious corrosion to the inner wall of the spray tower
