HF 反应炉是大型卧式迥转设备,传统的密封结构是填料函密封。由于密封点的温度高达400℃,同时,腐蚀性又极强,要找到能在这种工况下工作的密封填料非常困难,国内的氟化氢生产厂家采用浸渍石棉等纤维制品作为密封填料并不太理想。另外,HF 反应炉的炉体大,回转速度慢,回转炉筒的摆动量大,填料的回弹性很难弥补这一摆动量。因此,HF 反 HF reactor is a large horizontal transfer device, the traditional seal structure is stuffing box seal. As the sealing point temperature up to 400 ℃, at the same time, corrosive and extremely strong, to find the sealing filler can work under such conditions is very difficult, the domestic manufacturers of hydrogen fluoride impregnated asbestos and other fiber products as sealing filler is not too ideal. In addition, HF furnace furnace large, slow rotation, rotary drum large amount of swing, the resilience of the filler is difficult to make up for this amount of swing. Therefore, HF reverse
