磷铵生产系统采用原煤干燥产品时存在诸多问题,以半水煤气取代原煤作干燥热源,将造气工段生产的半水煤气直接送入磷铵装置的热风炉内燃烧后干燥产品,有效解决了存在问题,年可节约劳务费9万元、原煤倒运成本3.6万元,并且改善生产环境,将尾气中粉尘质量浓度大幅降低至50~70 mg/m3,产品质量得到保障。
Ammonia production system using coal raw materials, there are many problems when using raw water to replace the raw coal as a drying heat source, the gas production section of the semi-water gas directly into the ammonium phosphate plant hot air oven after burning dry products effectively solve the existing problems , Annual service savings of 90,000 yuan, 36,000 yuan coal transportation costs, and improve the production environment, the exhaust gas mass concentration of dust significantly reduced to 50 ~ 70 mg / m3, product quality is guaranteed.
