铸造车间Q365A型抛丸清理室基本上采用干法除尘和湿法除尘两种除尘方法。由于清理室工作时产生粉尘的浓度大,分散度大,因此从除尘的方法上看,采用一级旋风分离的干法除尘效率较低,在排风出口处仍有大量粉尘排出,造成污染。采用一级布袋除尘虽然效率较高,但布袋受大颗粒粉尘冲击易损坏,维修工作量和维修费用较大。有将旋风分离放在第一级,布袋除尘放在第二级组成的两级干法除尘,效果较好,可是由于系统中设备增加使阻力增大,既增加了除尘系统投资又加大了能耗而显
Casting workshop Q365A type shot blasting cleaning room is basically used both dry dust and wet dust removal methods. Due to the concentration of dust generated in the cleaning room is large and the degree of dispersion is large, from the method of dust removal, the dry dust removal efficiency using a first-class cyclone is low, and a large amount of dust is still discharged at the outlet of the exhaust air, causing pollution. Although the use of a bag of dust removal efficiency is high, but the bag by the impact of large particles of dust easily damaged, maintenance workload and maintenance costs. There will be cyclone on the first level, bag dust on the second level consisting of two levels of dry dust, the effect is better, but because of increased system equipment to increase resistance, both increased investment in the dust removal system and increased Energy consumption and significant
