[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0019] Example 1: like Figure 1 As shown, an enameled wire exhaust gas collection and treatment device includes a pretreatment component 3 and a catalytic component 5. The pretreatment component 3 is connected to the enameled wire production equipment through an air inlet pipe 1. The pretreatment component 3 is used to pretreat the exhaust gas. The catalytic component 5 is connected to the pretreatment component 3 and is used to catalytically combust the exhaust gas. The catalytic component 5 is connected to an exhaust pipe 7. The enameled wire exhaust gas collection and treatment device in this embodiment uses a pretreatment component 3, which can remove paint mist particles and a small amount of acidic gas in advance by washing the exhaust gas, thus avoiding clogging and corrosion of the catalytic equipment.

[0020] like Figure 2As shown, the pretreatment component 3 includes a rinsing tank 31. The top of the rinsing tank 31 is provided with a water distribution plate 34 and a water inlet 35. The water inlet 35 is located above the distribution plate. The water distribution plate 34 is evenly provided with a plurality of drainage holes. The bottom of the rinsing tank 31 is provided with a distributor 32 and a drain outlet 33. The distributor 32 is connected to the air inlet pipe 1. The drainage volume of the drain outlet 33 is controlled so that water remains at the bottom of the rinsing tank 31 and the liquid level is above the distributor 32. The exhaust gas enters the distributor 32 from the air inlet pipe 1. The distributor 32 evenly discharges the exhaust gas into the water body of the rinsing tank 31 and moves upward for the first cleaning. Then the exhaust gas enters above the liquid level and is rinsed by the water curtain left by the water distribution plate 34 during the rise of the exhaust gas, realizing the second cleaning and removing paint mist particles and a small amount of acidic gas.

[0021] like Figure 3 As shown, the catalytic assembly 5 includes a connecting pipe, a combustion chamber 54, and an exhaust pipe. The connecting pipe connects the top of the scrubbing pipe and the combustion chamber 54, and the exhaust pipe connects the combustion chamber 54 and the exhaust pipe 7. The combustion chamber 54 is equipped with a burner 53, and the top of the combustion chamber 54 is equipped with a catalytic reactor 55. The pretreated exhaust gas enters the combustion chamber 54 through the connecting pipe, and the burner 53 causes the fuel to burn, heating the exhaust gas to the catalytic combustion temperature. The exhaust gas then enters the catalytic reactor 55 and is catalytically decomposed into harmless gases, which are discharged from the exhaust pipe 7.

[0022] The connecting pipe is provided with a first heat exchange zone 51 and a second heat exchange zone 52. The first heat exchange zone 51 and the second heat exchange zone 52 are provided with heat exchangers 56. Both heat exchangers 56 are located in the exhaust pipe. By setting two heat exchangers 56, the pretreated waste gas can exchange heat with the high-temperature gas after catalytic combustion twice, so as to solve the problem of preheating the waste gas to a higher level and make reasonable use of waste heat.

[0023] The connecting pipe is connected to the washing tank 31 through the drying tank 4. The drying tank 4 is equipped with desiccant packing. The desiccant packing can absorb moisture in the exhaust gas and prevent excessive moisture from affecting subsequent catalytic combustion.

[0024] The exhaust pipe 7 is equipped with an exhaust fan 6.

[0025] The air intake pipe 1 is equipped with an air pump 2.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
