The foundry produces a large amount of smoke and dust during the production process. In order to meet the emission standards of smoke and dust, we have installed the environmental protection equipment of the casting workshop - pulse bag filter.
The foundry has chosen a new type of economical and efficient pulse bag filter that can be continuously improved. It retains the advantages of the original model of dust collector, such as high dust collection efficiency, large processing air volume, stable performance, simple and convenient operation, long filter bag life, and small maintenance workload. It has undergone Chinese reforms in terms of structure and pulse valves, solving the problems of outdoor placement and low compressed air source pressure. Widely researched dust collection systems for improving the dust and smoke generated by industrial and mining construction enterprises such as mining, aluminum melting furnace smelting, mechanical design and manufacturing, chemical production products, cement and building materials, and grain product processing. The material analysis of the filter bag of the dust collector in the foundry generally uses polyester needle felt, which allows a continuous data usage environment temperature of less than 120 ℃. For example, if the filter bag uses Metas high-temperature needle felt, it allows students to use different temperature ranges up to 204 ℃. If the temperature of the treated exhaust gas is significantly higher than the allowable temperature based on the above filter material, cooling control measures should be taken before the exhaust gas directly enters the dust collector. If this series of dust collectors are used in cold areas or when the flue gas is below zero, insulation material heating devices should be added, and the shell should also be changed accordingly.
Characteristics of Pulse Bag Filter in Foundry
After the structural improvement, the sealing performance of the equipment has been improved, with a leakage rate of less than 2%.
After the improvement of the bag changing door cover and the fixing method of the filter bag, it is more convenient for equipment maintenance and repair.
3. The original agitator shell of the ash removal part of the enterprise has been removed, which has expanded the teaching effect of ash removal, sealed tightly, discharged quickly, and reduced the amount of maintenance. Based on our company's experience in dust removal and control in the foundry industry in recent years, and through on-site research and investigation of every student's environmental protection building project, we have gained an understanding of the characteristics of such dust. Through communication with engineers in various aspects, we have fully analyzed and demonstrated that bag filters are a good way to remove smoke from electric furnaces in foundries, and their effectiveness in controlling black smoke is good, Meet the emission market demands of various regions.
