Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hot galvanizing production environment-friendly equipment, in particular to a hot galvanizing zinc fume dust removal device. BACKGROUND

[0002] Hot galvanizing is a common metal anticorrosion treatment process, in the process of immersing the workpiece into molten zinc liquid, a large amount of zinc fume containing zinc vapor, zinc oxide dust and other harmful impurities will be generated. If these zinc fumes are directly discharged into the air, not only will it cause serious pollution to the surrounding environment, but also will endanger the health of the operating personnel, at the same time, as a valuable metal resource, direct discharge will also cause waste of resources. At present, the existing hot galvanizing zinc fume dust removal device mostly adopts filter bag dust removal method.

[0003] However, the existing filter bag dust removal device has the following disadvantages:

[0004] (1) The dust in the zinc fume is easily attached to the surface of the filter bag due to factors such as electrostatic adsorption and mechanical adhesion, and the conventional dust removal method cannot achieve complete stripping of the dust, which leads to easy blockage of the filter bag and increase of the filtration resistance, and the filter bag needs to be replaced frequently, which not only increases the equipment maintenance cost, but also affects the production efficiency due to shutdown maintenance;

[0005] (2) After the dust in the zinc fume is blown out through the back blowing pipe in the filter bag, it is easily adhered to the inner wall of the dust removal box, and it is difficult to remove quickly;

[0006] (3) After the filter bag filters the dust in the zinc fume, combustible zinc oxide dust is trapped, and the filter bag will accumulate static electricity due to friction and induction during filtration, and release sparks when the voltage exceeds the threshold, which can easily cause dust explosion or ignite organic volatile matter, and there is a safety hazard;

[0050] In work, hot galvanizing zinc fume is introduced into the square box 9 from the fume inlet pipe 10, and then the zinc fume is introduced into the dust removal box 1, and then the zinc fume enters the filter bag 3, and the filter bag 3 is used to filter the dust in the zinc fume, and the filtered zinc fume enters the air outlet box 11 and is discharged through the air outlet pipe 12. Start the air blower 4, and the air blower 4 blows air into the filter bag 3 through the back blowing pipe 5. The compressed air is quickly introduced into the filter bag 3 through the back blowing pipe 5. The airflow forms a high-speed jet through the air outlet of the back blowing pipe 5, and instantly rushes into the filter bag 3. The high-speed back blowing airflow makes the filter bag 3 turn into an internal blowing and swelling state. The surface of the filter bag 3 swells violently, and the airflow impact breaks the adhesion between the dust layer and the surface of the filter bag 3.
