[0030] Please refer to Figure 1 、 Figure 2 and Figure 3, cleaning mechanism 2, the cleaning mechanism 2 is located between the heat exchanger 4 and the gas pipe 7 and is used to clean the inside of the gas pipe 7, the cleaning mechanism 2 includes a water supply component, a reinforcement component and a recovery component, the water supply component is located on one side of the heat exchanger 4 and is used to supply water to the inside of the gas pipe 7 while cleaning it, the reinforcement component is located between the heat exchanger 4 and the gas pipe 7 and is used to reinforce the water supply component, the recovery component is located at the bottom of the two exhaust gas treatment towers 5 and is used to recycle clean water, the water supply component includes a water tank 21 fixed to one side of the heat exchanger 4, a water supply pump 23 is installed inside the water tank 21, the water outlet end of the water supply pump 23 is connected to the water outlet pipe 25, the water outlet pipe 25 is connected to the gas pipe 7, the gas pipe 7 and A control valve 26 is installed at one end of the connection of the outlet pipe 25.

One end of the two reinforcement plates 24 is fixed to the heat exchanger 4. The recovery component includes a receiving plate 27 installed at the bottom of the two exhaust gas treatment towers 5. A recovery box 211 is fixed to the bottom of the receiving plate 27. The bottoms of the two exhaust gas treatment towers 5 are both connected to recovery pipes 28. The two recovery pipes 28 extend to the interior of the recovery box 211 and are commonly connected to a connecting pipe 29. A water pump 210 is installed inside the recovery box 211.

[0033] First, pull the movable rod to drive the baffle to move, and the movement of the baffle drives the spring 35 to contract. After the contraction of the spring 35, the baffle drives the insertion rod 38 to move, and the movement of the insertion rod 38 separates it from the disassembly plate 31. Then move the positioning plate 39 upward so that it enters the disassembly seat 33 through the opening groove, enters the disassembly seat 33 through the positioning plate 39, and then uses the elastic force of the spring 35 to make it conflict with the baffle. Then rotate the rotating plate 36 to separate it from the control plate 37, pull the control plate 37 to drive the positioning rod 310 to move, so that the positioning rod 310 moves and separates it from the mounting plate 32. Finally, pull the receiving plate 27 to drive the recovery pipe 28 to separate from the exhaust gas treatment tower 5, so that the recovery box 211 can be separated synchronously.
