Abstract

The invention relates to a curtain-type soot treatment and purification system for hot galvanizing and a method thereof. The system comprises a galvanizing soot collecting device and a galvanizing soot purification device, wherein the galvanizing soot gathering device comprises a curtain system, a supporting system, a drive system and an air draft pipeline system; the galvanizing soot purification device comprises a purification processing tower and a centrifugal fan. In the galvanizing production process, when galvanizing travelling vehicle travels above a zinc pot, a piece to be plated is dipped into zinc bath, the curtain quickly lowers to form a gas hood; the air draft pipeline system on the top automatically extracts soot and introduces the soot into the purification processing tower; after being purified and adsorbed, soot is discharged into atmosphere; after galvanization ends, the curtain quickly rises and returns, and a plating piece moves to the subsequent processing working procedure. The invention has favorable collection, purification and adsorption effect on galvanizing soot, has low energy consumption, simple structure, convenient manufacture and maintenance, small floor area and small affect on galvanizing effect, and is suitable for liner hot galvanizing production lines, and the collection efficiency is above 95%.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing smoke and dust treatment in hot-dip galvanizing production, in particular to a curtain-type smoke treatment and purification system for hot-dip galvanizing and a method thereof. Background technique [0002] Hot-dip galvanizing is one of the important means to improve the atmospheric corrosion resistance of the surface of steel parts. It first pretreats the surface of steel parts, and then immerses them in molten zinc liquid to form a layer of zinc metal protective coating on the surface of steel parts. Solvent treatment is an important treatment process before hot-dip galvanizing. It can not only make up for the possible shortcomings of the previous processes, but also activate the steel surface and improve the quality of the coating, which is not available in other steel anti-corrosion processes. The most commonly used fluxing solvent is zinc chloride (ZnCl 2 ) and ammonium chloride...
