摘要
分析清河污泥干化厂流化床工艺全年的运行情况,发现其电单耗约为91 kW.h/t湿泥,气单耗约为59 m3/t湿泥;包括电费和燃气费用的直接成本约为200元/t湿泥;干颗粒粒径与直接成本呈指数关系,干颗粒粒径越小则直接成本越低,反之则直接成本越高。破碎机刀头使用一段时间后,由于被磨损,实现不了泥饼的破碎功能,需要进行更换。要延长破碎机刀头的使用寿命,首先得提高破碎机刀头的耐磨性。
Through analyzing the annual operation of fluidized bed process in Qinghe Sludge Drying Plant, it was found that power consumption was about 91 kW h/t, and gas consumption was about 59 m3/t. The direct cost including electricity and gas expenses was about 200 yuan/t. There existed an exponential relationship between the dry particle size and the direct cost, the smaller the dry particle size, the lower the direct cost, and vice versa. After being used for some time, the crusher head needed to be replaced due to wear and that the cake could not be broken. To improve the service life of crusher head, the wear resistance of crusher head should be increased.
