TECHNICAL FIELD

[0001] The utility model relates to scrap metal crushing technical field especially relates to a scrap metal crushing dust removal equipment. BACKGROUND

[0002] A large amount of dust is generated in the scrap metal crushing process, which not only pollutes the air, but also may cause greater harm to the environment. For example, when scrap steel is crushed, a large amount of dust is generated due to the impact, friction and high-speed rotation of the material. If dust removal is not performed, the dust will spread into the air, resulting in a decrease in air quality. The dust generated during the crushing process contains metal particles, soil, rust and other impurities. If these dust is not removed in time, it will cause harm to the respiratory system of the operator and increase the risk of occupational diseases.

[0003] In the prior art, the dry dust removal (such as bag dust removal) has limited ability to capture fine dust, and ordinary water mist spraying cannot effectively settle high-concentration dust (the water curtain formation method is single, the water flow is unevenly distributed, and part of the dust may bypass the water curtain and directly enter the exhaust pipe, reducing the dust removal effect), resulting in that the exhaust gas still contains a large amount of particulate matter. Therefore, we propose a scrap metal crushing dust removal equipment to solve the above problems. SUMMARY
