[0024] Working principle

[0025] In operation, this invention uses a tail gas inlet fan 1 to transport coking desulfurization tail gas from the conveying pipe 2 to the inlet pipe 33. The gas then passes through a side conduit 34 and into the processing tank 31 via the outlet pipe 35. An arc-shaped plate 32 guides the air bubbles to the upper left, directing impurities to the left for easier one-sided removal. Simultaneously, the gas passes through a guide filter 42 and is transported into the outlet frame 41. An observation hood 44 stores the filtered residue. The guide filter 42 does not interfere with the process. The water is conveyed downwards. The control valve 83 is opened, and ozone is supplied to the treatment tank 31 through the ozone generator 81 via the air supply pipe 82 and the discharge pipe 84 to treat the exhaust gas. The air is then discharged after being filtered through the exhaust filter 7 in the exhaust pipe 6 by the auxiliary fan 5. When water needs to be discharged, the control valve 83 is closed and the discharge valve 85 is opened to discharge the water in the treatment tank 31 through the discharge pipe 84. During operation, the discharge valve 43 is closed, and then the discharge valve 45 is opened to treat the material residue inside the observation hood 44 to the outside.
