Description
Technical Field
The utility model relates to a zinc cigarette that produces in the hot-galvanize production administers technical field, especially relates to a hot child's flue gas absorbing device.
Background
Hot dip galvanizing, also known as hot dip galvanizing, is a method of dipping steel members into a molten zinc bath to obtain a metal coating. In recent years, along with the rapid development of high-voltage power transmission, traffic and communication industries, the protection requirements on steel parts are higher and higher, and the demand of hot galvanizing products is also continuously increased. When the zinc pot is in normal operation, the surface of the zinc pot quickly forms an oxide layer, so that the smoke generation amount is less. When the workpiece is immersed in and lifted out of the zinc pot, the fume is greatly increased due to the stirring and the volatilization of the plating assistant agent on the workpiece. When the work piece in the zinc pot is subjected to hot galvanizing, a large amount of smoke is generated, and the generated principle is explained as follows: after the workpiece is pickled and derusted, the workpiece is treated by solvent ammonium chloride, and after being dried, the surface of the workpiece is completely wrapped by ammonium chloride. At the moment when the workpiece enters the galvanizing pot, due to the action of high temperature, ammonium chloride is rapidly decomposed to generate salts such as ferric chloride, zinc oxide, ammonium chloride and the like and metal oxide smoke dust, wherein ammonium chloride is taken as the main component, and the particle size of the smoke dust is extremely fine and is within the range of 0.0 l-1 mu m.
At present, the zinc fume treatment mode generated in the hot galvanizing production process is mainly that an air suction opening (hereinafter referred to as side suction) is arranged on the side of the edge of a zinc pot, and the zinc fume is sucked to a dust remover through a pipeline for dust removal treatment and is discharged after reaching the standard. It mainly has the following disadvantages:
1. The side suction mode has a strong absorption effect on zinc smoke generated at the edge of the zinc pot, and the zinc smoke can reach the standard and be discharged after being dedusted by the deduster, but the zinc smoke generated in the middle of the zinc pot is difficult to be effectively absorbed, particularly, the yield is pursued in the current hot galvanizing industry, the zinc smoke in the middle of the zinc pot is difficult to be absorbed under the condition that the width of the zinc pot is continuously widened, the unorganized discharge is serious, and the environment is difficult to reach the standard.
2. The side suction mode is that the suction openings are arranged on two sides of the zinc pot, and in order to ensure the absorption effect, one set of side suction needs to be provided with two high-power fans to work simultaneously, so that a field is formed, and electricity is wasted.
3. The side suction mode is along limit side installation inlet scoop on the zinc pot, and is too near apart from the zinc liquid surface, and the one hand induced drafts with higher speed the oxidation of zinc liquid surface, generates a large amount of zinc oxide, causes the raw materials extravagant, and on the other hand takes away a large amount of zinc pot heats when induced drafting, causes the heat to run off, increases energy cost.
