Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial dust removal, in particular to a dust remover for spherical zinc powder production and a dust removal process thereof. BACKGROUND

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

[0003] Therefore, it is necessary to use a dust removal device to collect the atmospheric pollutants and dust generated during the production of spherical zinc powder. The dust removal device usually uses a bag filter, but the accumulation of dust in the bag filter may block the pores of the filter bag, increasing the air flow resistance and reducing the dust removal efficiency. As the amount of dust accumulation increases, the filtering capacity of the filter bag gradually weakens, allowing more dust particles to escape capture. When the dust settles and accumulates on the filter bag, the pores become smaller and the air flow rate increases. When the speed increases to a certain extent, the dust layer may form "pinholes", allowing a large amount of filtered air to flow through these low-resistance pinholes, resulting in "leakage" and further affecting the dust removal effect. In severe cases, the accumulation of dust may cause abnormal pressure inside the dust remover, affecting 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 remover for spherical zinc powder production and a dust removal process thereof to solve the above problems. SUMMARY
