The waste gas pipe 1 comprises a smoke inlet end and a smoke outlet end, and low-temperature waste gas enters from the smoke inlet end and is discharged from the smoke outlet end after being processed. Along the direction of exhaust gas motion, arrange heat exchanger 3 and catalysis box 2 in proper order in exhaust pipe 1, catalysis box 2 arranges in exhaust pipe promptly and is close to out cigarette end one side, and heat exchanger 3 arranges in exhaust pipe and is close to into cigarette end one side. The catalytic box 2 is provided with a vent hole 21 for the exhaust gas to pass through the catalytic box 2. Catalyst is correspondingly placed in the catalytic box 2 according to the type of the waste gas, and the waste gas enters the catalytic box 3 from the air holes 21 and is subjected to catalytic combustion through the catalyst in the catalytic box 3.
The circulation pipe includes a first heat exchange pipe 41, a second heat exchange pipe 42, and a radiator 43.
The first heat exchange tube 41 is arranged across the heat exchanger 3, and the water inlet end of the first heat exchange tube 41 is communicated with the water outlet end of the radiator 43, and the water outlet end is communicated with the water inlet end of the radiator 43. The second heat exchange tube 42 is arranged across the catalytic box 2, the water inlet end of the second heat exchange tube 42 is communicated with the water outlet end of the radiator 43, and the water outlet end of the second heat exchange tube 42 is communicated with the water inlet end of the radiator 43.
The water pump 5 is disposed on the circulation pipe for driving the flow of the coolant in the circulation pipe.
In this embodiment, for smooth flow of the coolant, the water inlet end of the water pump 5 is connected to the water outlet end of the heat sink 43, and the water outlet end of the water pump 5 is connected to the water inlet ends of the first heat exchanging pipe 41 and the second heat exchanging pipe 42, respectively. The water inlet end of the water pump 5 can be communicated with the water outlet ends of the first heat exchange tube 41 and the second heat exchange tube 42, and the water outlet end of the water pump 5 can be communicated with the water inlet end of the radiator 43.
For better heat dissipation of the catalyst in the catalyst box 2, the portion of the second heat exchange pipe 42 located in the catalyst box 2 is split into a plurality of pieces to increase the heat exchange area and speed. Meanwhile, the portion of the second heat exchange pipe 42 located inside the catalyst cartridge 2 is also perpendicular to the direction of flow of the exhaust gas to facilitate heat exchange.
In order to better ensure that the catalyst in the catalytic box 2 is in the temperature interval with the highest activity, the high-temperature exhaust gas catalytic treatment device also comprises a temperature measuring instrument 6.

The cooled waste gas is introduced into the catalytic box 2 for catalytic combustion, and the generated heat is absorbed by the low-temperature cooling liquid in the second heat exchange tube 42, so that the activity reduction caused by the overhigh temperature of the catalyst in the catalytic box 2 is avoided. The high-temperature coolant generated after heat exchange in the first heat exchange tube 41 and the second heat exchange tube 42 flows into the radiator 43 to dissipate heat, and is changed back to the low-temperature coolant again, thereby completing the circulation.
