[0018] During operation, the dry oil gas generated by the drying of the sludge treatment kiln enters the spray tower 11 from the dry gas inlet pipe 12, and then the oil gas flows upward in the spray tower 11. At this time, the lower spray head 10 will spray the oil gas for the first time, which will reduce the temperature of the oil gas, and a part of the oil gas will condense, and the dust in the oil gas will be sprayed to remove it. The dust and liquid will fall to the bottom of the spray tower 11 and be discharged from the liquid outlet pipe 13. The rising oil gas will be sprayed for the second time through the upper spray head 10, and then the non-condensable gas will enter the outlet pipe 2 from the vent, and then be discharged through the non-condensable gas outlet pipe 4.
