The implementation principle of the embodiment is as follows:

after the driving motor 351 is started, the driving gear 352 can be driven to rotate, and the driving gear 352 can drive the driven gear 353 engaged with the driving gear 352 to rotate, so that the two driven gears 353 engaged with each other can rotate oppositely. Under the drive of the driven gear 353, the two rotating rollers 33 rotate in opposite directions, and when the rotating rollers 33 rotate in opposite directions, the tooth piece 34 can drive the exhaust gas and bring the exhaust gas into a cavity formed by the tooth piece 34 and the air exhaust shell 32, and along with the continuous rotation of the rotating rollers 33, the exhaust gas moves from the air exhaust pipe 31 into the air delivery pipe 36 under the drive of the tooth piece 34. The two rotating rollers 33 can continuously convey the exhaust gas in the exhaust pipe 31 to the air pipe 36.

The exhaust gas in the gas pipe 36 is delivered into the tank 41 below the heat exchange plate 43, and then the exhaust gas moves upward in the tank 41. During this process, the spray member 5 is kept activated to spray water. The water pipe 51 delivers clean water into the support pipe 53, and the water in the support pipe 53 is first delivered into the connecting pipe 55, then delivered into the connecting pipe 55 and the hollow cavity of the support pipe 53 through the through hole 56, finally delivered into the spray pipe 66, and sprayed out through the spray hole 67. Since the spray holes 67 on the end side wall of the spray pipe 66 also spray clean water, and the spray pipe 66 is tangent to the virtual circumference of the baffle ring 6, the clean water sprayed from the spray holes 67 on the end side wall also gives the baffle ring 6 a driving force tangent to the baffle ring 6 by a reaction force. A plurality of these driving forces can drive and keep off 6 rotations of ring, and the clear water that erupts becomes the drop of water under the effect of centrifugal force at the rotation in-process to make spraying hole 67 in spun clear water can be more even spray 41 in jar body.

In the rotation process of the retainer ring 6, the rolling fit of the first groove 61, the second groove 62 and the balls 63 can make the rotation process of the retainer ring 6 smoother, thereby not only reducing the resistance of the rotation of the retainer ring 6, but also reducing the abrasion of the retainer ring 6 during the rotation. And the matching of the clamping groove 65 and the sealing ring 64 can reduce the possibility of leakage of clean water.

The water that sprays in jar 41 passes through the passageway that heat transfer plate 43 encloses to carry out the heat exchange with the waste gas in the heat transfer plate 43, thereby with waste heat transfer to aquatic on the waste gas, and at the in-process that sprays, the harmful substance mass energy in the waste gas can transfer to aquatic, thereby makes the waste gas that sprays can pass through the harmless emission of waste gas discharge pipe 7. And the hot water after heat exchange with the waste gas is conveyed to a process needing hot water through the hot water recovery pipe 8 so as to recycle the waste heat. In the process, the contact area of the spraying water and the waste gas can be greatly enlarged by the heat exchange plates 43 which are arranged in a crossed mode, and therefore the heat exchange effect is improved.
