[0002] In oil shale low-temperature dry distillation process, Fushun type dry distillation furnace is the key equipment. Shale enters from the top of dry distillation furnace, rotates with water basin below the furnace body, completes low-temperature dry distillation process through preheating section, dry distillation section, occurrence section, waste residue is discharged through ash discharge device in water basin, and needs cooling water to cool down waste residue before transportation. However, the current cooling water level is adjusted by manually controlling water adding valve, which is difficult to accurately control. When too much cooling water is added, it will overflow to the lower waste residue belt, causing the belt to slip, lose rotation and run off, increasing the risk of belt tearing and other faults. When too little cooling water is added, the water level height cannot achieve water sealing, and the gas in the dry distillation furnace will break through the water seal and burst out, which is not conducive to environmental protection and poses a safety hazard.
