Zero-emission acid mist treatment device of hot-dip galvanizing closed workshop

Abstract

The invention discloses a zero-emission acid mist treatment device of a hot-dip galvanizing closed workshop. The zero-emission acid mist treatment device comprises a water washing tower and an alkaliwashing tower, wherein an air inlet in the bottom part of the water washing tower is connected with a draught fan; the draught fan is connected with multiple acid mist sucking openings formed in the side wall of the closed workshop through a wind sucking main pipe; the acid mist sucking openings stretch into the closed workshop; a wind outlet in the top part of the water washing tower is connectedwith an air inlet in the bottom part of the alkali washing tower; a wind outlet in the top part of the alkali washing tower is connected with an air sealing device on an acid washing tank in the closed workshop through a wind return pipe; the air sealing device comprises a frame-shaped air sealing main pipe connected with the wind return pipe and multiple air sealing branch pipes arranged betweentwo opposite side walls of the frame-shaped air sealing main pipe; the frame-shaped air sealing main pipe is arranged on the edge wall of the acid washing tank; the air sealing branch pipes are arranged on separating walls of the acid washing tank; multiple rows of wind outlets are formed in the side walls of the air sealing branch pipes. According to the zero-emission acid mist treatment devicedisclosed by the invention, not only air sealing on the acid washing tank can be realized, volatilization of hydrochloric acid in the acid washing tank can be reduced and the acid washing effect of aworkpiece can be increased, but also zero emission of gases is completely realized.

Description

technical field [0001] The invention relates to a zero-discharge acid mist treatment device for a hot-dip galvanized closed factory building. Background technique [0002] The hot-dip galvanizing anti-corrosion process on metal surfaces has a long history, but with the continuous changes in the market economy in recent years, the hot-dip galvanizing industry has also developed on a large scale. For the hot-dip galvanizing process, this not only increases the production pressure such as cost, but also makes enterprises face major problems as the competition in the electro-galvanizing industry intensifies. In response to this problem, an industrial high-tech strategic plan was proposed. When the traditional process cannot meet the needs of the enterprise, the reform of the hot-dip galvanizing process has become the main trend of enterprise development. The domestic hot-dip galvanizing process is still at a relatively low level. The high-end production scenario not only lacks ...

In response to this problem, an industrial high-tech strategic plan was proposed. When the traditional process cannot meet the needs of the enterprise, the reform of the hot-dip galvanizing process has become the main trend of enterprise development. The domestic hot-dip galvanizing process is still at a relatively low level. The high-end production scenario not only lacks automated electro-galvanizing equipment, but also increases the workload of workers, and also causes great pollution to the environment. The traditional electro-galvanizing production process will produce acid mist, which has a great impact on workers, the environment and equipment. to infringe
