将料浆法粉状磷酸一铵装置干燥尾气处理系统由沉降除尘加喷淋洗涤流程改为文丘里酸洗后除沫加文丘里水洗后除沫流程,消除了沉降室的清理时间,提高了装置的运行效率和除尘洗涤效率,使排放尾气中尘、氨、氟含量大大低于国家排放标准,年创效益约1 300万元。 The pulverized powder ammonium monoammonium phosphate plant dry exhaust gas treatment system from sedimentation and dedusting spray cleaning process to Venturi pickling plus foam venturi wash after the foam removal process to eliminate the settling chamber cleaning time and improve The operating efficiency of the device and the efficiency of dust removal and washing make the dust, ammonia, and fluorine content of the exhaust gas discharged much lower than the national emission standards, and the annual profit will be about 13 million yuan.
