[0034] The flue gas and waste generated in the workshop are sent into the second tower body through the flue gas suction device for cyclone spraying to remove oil and other substances in the gas. The gas after spraying is then sent into the first tower body for filler spraying to remove substances in the gas, and finally it is sucked into the atmosphere by the exhaust fan.
