摘要
以某明胶企业9万Nm3/h风量磷酸氢钙车间烟气除尘项目为例,介绍了"粉尘预荷电+三相紊流筒高效洗涤组合技术"的工艺流程及关键技术设备,磷酸氢钙车间烟气处理后颗粒物排放浓度≤120mg/Nm3,排放速率≤4.8kg/h,符合相关标准。此工艺路线环保减排效益显著,为明胶企业实现磷酸氢钙生产优化、环保改造提供了一种可行可靠的技术参考和工艺借鉴。
By taking the flue gas dust removal project of 90 000 Nm~3/h air quantity calcium hydrogen phosphate workshop in a gelatin enterprise as an example, this paper mainly introduces the technological process and key technical equipment of "dust pre-charging + three-phase turbulent cylinder, high-efficiency and washing combination technology". After flue gas treatment in the workshop of calcium hydrogen phosphate, the emission concentration of particulate matter is ≤120 mg/Nm and the emis?sion rate is ≤4.8 kg/h, which conform to the relevant standards. This process has remarkable environmental protection and emission reduction benefits. It provides a feasible and reliable technical reference and process reference for the gelatin enterprises to realize the production optimization of calcium hydrogen phosphate and environmental protection transformation.
