Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical dust removal equipment, and specifically refers to a metallurgical dust removal structure. Background Technique

[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and using various processing methods to make metals into metal materials with certain properties. Metallurgy has a long development history, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of modern iron and steel smelting.

[0003] During the metallurgy process, a large amount of waste dust particles are often generated, so dust extraction equipment and external discharge pipes need to be installed in the metallurgical plant. However, the directly discharged air will cause environmental pollution to the surrounding area. Therefore, a dust removal structure generally needs to be installed in the external discharge pipe before discharging. Most of the existing dust removal structures use bag dust removal, but bag dust removal often requires regular cleaning. Therefore, water filtration has recently been adopted. However, in direct water filtration, the gas is prone to insufficient contact with water, resulting in insufficient water adsorption. At the same time, some humid gases will also carry some fine dust and be discharged, and the gas cannot be filtered sufficiently. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a metallurgical dust removal structure that can filter dust sufficiently in view of the deficiency of water filtration of dust in the above-mentioned background technique.
