Description

Technical Field

[0001] The invention relates to the technical field of industrial dust removal, and in particular to a dust collector for producing spherical zinc powder and a dust removal process thereof. Background Art

[0002] Some air pollutants may be generated during the production of spherical zinc powder. For example, in the distillation condensation method, metal zinc is heated to a high temperature to volatilize zinc vapor. If not handled properly, these vapors may escape into the air. Similarly, in the atomization method, zinc liquid is atomized into fine metal powder by a high-pressure gas medium, which may also produce dust pollution. These pollutants mainly include zinc vapor, particulate matter, etc., which may have adverse effects on the surrounding atmospheric environment.

[0003] Therefore, dust removal equipment is needed to collect the atmospheric pollutants and dust generated during the production of spherical zinc powder. Dust removal equipment usually uses bag dust collectors. Dust accumulation in the bags will block the pores of the filter bags, resulting in increased air flow resistance, thereby reducing dust removal efficiency. As the amount of dust accumulation increases, the filtering capacity of the filter bags gradually weakens, so that more dust particles cannot be effectively captured. When dust settles and accumulates on the filter bags, the pores become smaller and the speed of air passing through increases. When the speed increases to a certain level, the dust layer may produce "pinholes", and the filtered air flows through these pinholes with low resistance in large quantities, forming an "air leakage" phenomenon, which further affects the dust removal effect. When the dust accumulation is serious, it may cause abnormal pressure inside the dust collector and affect the stable operation of the equipment. In addition, dust accumulation may also cause vibration and noise problems of the equipment.

[0004] Therefore, it is necessary to invent a dust collector for spherical zinc powder production and a dust removal process thereof to solve the above problems. Summary of the invention
