Summary of the rectification plan for the dust removal equipment in the foundry: The first set of equipment in the foundry is a wet dust collector, which has a dust removal effect that does not meet the national emission standards, and also has secondary pollution, which requires rectification.
Problems in the rectification plan of the dust removal equipment in the foundry: Because the previous wet dust collectors in the foundry were difficult to control the water washing position, the dust removal efficiency was often unstable, and water was inseparable during the work process. Therefore, water resources and water cleaning were provided. The troublesome procedure of handling mud has brought a series of problems to the company, and it is accompanied by secondary pollution problems and the dust removal effect cannot meet China's existing emission standards, so the Environmental Protection Agency requires its rectification.
Rectification plan of dust removal equipment in foundry:
、将铸造厂 以前的湿式除尘器拆除，改换成布袋除尘器 1. Remove the former wet dust collector from the foundry and replace it with a bag dust collector
、滤料选型采用进口防水材质，采用化学技术通过聚四氟乙烯浸透处理，湿型铸造的含湿粉尘专用。 2. The filter material is selected from imported waterproof materials, chemical technology is used for PTFE infiltration treatment, and wet casting is used for wet dust.
、在脉冲阀喷嘴至除尘器滤袋间设计挡水装置，可以防止压缩空气气源中残余水汽进入除尘器而发生袋糊。 3. Design a water blocking device between the pulse valve nozzle and the dust collector filter bag, which can prevent the residual water vapor in the compressed air source from entering the dust collector and causing bagging.
、除尘器采用覆膜滤料，滤速选取为 1.4-1.7m/min ，滤袋本身不易被粉尘黏附，易于清灰 ; 4. The dust collector uses membrane-coated filter material, and the filter speed is selected to be 1.4-1.7m / min . The filter bag itself is not easy to be adhered by dust and is easy to clean .
整个车间，铸造造型线、落砂线、旧砂沸腾冷却、旧砂磁选、筛分、输送及混砂系统，由 2 台 LCPM 袋式除尘器承担。 5. In the entire workshop, the casting molding line, falling sand line, used sand boiling cooling, used sand magnetic separation, screening, conveying and sand mixing systems are undertaken by two LCPM bag dust collectors.
运营效果备安装调试后测得的工况条件下排放口粉尘浓度为 25mg/m3 ，除尘效率达到 99.7% ，符合国家排放标准！ The final operation effect of the foundry's dust removal equipment rectification plan . The dust concentration at the discharge port under the working conditions measured after installation and commissioning is 25mg / m3 , and the dust removal efficiency reaches 99.7% , which meets national emission standards!
