[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Specific implementation examples are given below.

[0037] Please see Figures 1-6 The present invention provides an electromagnetic heating coil exhaust gas combustion device with a purification and filtration mechanism, including a combustion component 1 and a cooling component 2 located on the right side of the combustion component 1. A filter component 3 is provided on the right side of the cooling component 2, a connecting mechanism 4 is provided on the left side of the combustion component 1, and a limiting mechanism 5 is provided on the top of the filter component 3.

[0038] like Figure 1 , Figure 3 and Figure 5 As shown, the cooling component 2 includes a spray tower 201. A water collection tank 202 is located at the bottom of the spray tower 201. A filter plate 203 is fixedly connected to the top of the water collection tank 202. A circulation pump 205 is connected to the right side of the water collection tank 202, and a water supply pipe 206 is connected to the right side of the circulation pump 205. One end of the water supply pipe 206 is connected to the circulation pump 205, and the other end is connected to a first spray frame 207. A connecting pipe 2013 is connected to the middle and lower part of the right side of the water supply pipe 206. A second spray frame 2014 is connected to the right side of the middle connecting pipe 2013, and a third spray frame 2017 is connected to the right side of the lower connecting pipe 2013. The first spray frame 207 is annular, and several high-pressure nozzles 208 are fixedly connected to the inner wall of the first spray frame 207. A support frame is fixedly connected to the bottom of the first spray frame 207. The support frame has several swirl plates 209 fixedly connected inside. The support frame has installation slots on the left and right sides, and fixed rods 2010 are fixedly connected inside the installation slots. Pull rods 2011 are fixedly connected to the opposite sides of the two fixed rods 2010. Each pull rod 2011 is sleeved with a support spring 2012. The fixed rods 2010 are elastically connected to the spray tower 201 through the support springs 2012. The second spray frame 2014 is annular. Several spray pipes 2015 are fixedly connected inside the second spray frame 2014. Orifice plate corrugated packing 2016 is set below the second spray frame 2014. Several conical spray heads 2018 are fixedly connected to the bottom of the third spray frame 2017. A water outlet pipe 204 is connected to the front of the water collection tank 202. A connecting pipe 2019 is connected to the right side of the spray tower 201.

[0039] The above scheme involves: discharging the disinfected exhaust gas from the top of the spray tower 201 into the interior of the spray tower 201; starting the circulation pump 205; and inputting spray water from the water supply pipe 206 into the first spray frame 207, which is then sprayed out through the high-pressure nozzle 208 to generate fine droplets, thereby rapidly cooling and breaking up the high-temperature gas mass. Spray water is then input from the connecting pipe 2013 into the second spray frame 2014, and sprayed out through the spray pipe 2015. This, combined with the perforated plate corrugated packing 2016, allows the gas and liquid phases to form a liquid film on the surface, enabling efficient heat and mass transfer. Finally, spray water is input from another connecting pipe 2013 into the third spray frame 2017, and sprayed out through the conical spray nozzle 2018, providing a final wash for the discharged gas and acting as a liquid seal to prevent short circuits.

[0040] like Figure 1 and Figure 2 As shown, the combustion assembly 1 includes an electromagnetic coil 101. A ceramic fiber insulation layer is fixedly connected to the outside of the electromagnetic coil 101. An air inlet pipe 102 is connected to the left side of the electromagnetic coil 101, and an air outlet pipe 103 is connected to the right side of the electromagnetic coil 101. A connecting mechanism 4 is provided on the left side of the combustion assembly 1. The connecting mechanism 4 includes a connecting seat 401. A sealing ring 402 is provided on the left side inside the connecting seat 401. A movable collar 403 is slidably connected to the outside of the connecting seat 401. Connecting rods 404 are movably pinned to the four sides of the movable collar 403. A movable plate 405 is movably pinned to the right side of each connecting rod 404. Several guide rods 406 are fixedly connected to the side of each movable plate 405 near the center of the connecting seat 401. A fixing spring 407 is sleeved on the outside of the several guide rods 406. A fixing block 408 is fixedly connected to the side of each guide rod 406 near the center of the connecting seat 401. The fixing block 408 is elastically connected to the connecting seat 401 through the fixing spring 407.

[0041] The above method involves inserting the air intake pipe 102 into the connecting seat 401. Since the fixing block 408 is elastically connected to the connecting seat 401 through the fixing spring 407, the fixing blocks 408 on all four sides move towards each other under the elastic force of the fixing spring 407, thus completing the fixed installation of the air intake pipe 102. Toxic waste gas is injected into the interior of the electromagnetic coil 101 through the air intake pipe 102. After the electromagnetic coil 101 is energized, it can quickly heat up to a high temperature, rapidly burning the toxic waste gas inside, thereby quickly removing the toxic part inside.

[0042] like Figure 1 , Figure 4 and Figure 6As shown, a filter assembly 3 is provided on the right side of the cooling component 2. The filter assembly 3 includes an activated carbon box 301, which is connected to the air outlet pipe 103. A movable frame 302 is slidably connected inside the activated carbon box 301. Handles 303 are fixedly connected to the front and rear sides of the top of the movable frame 302. Filter screens 304 are connected to the left and right sides of the movable frame 302. A guide groove 308 is provided in the middle of the filter screen 304. Movable gears 307 are meshed on opposite sides of the two guide grooves 308. The movable gears 307 are fixedly connected to the activated carbon box 301. Several sets of sliding grooves are provided on the upper and lower sides inside the movable frame 302. Each set of sliding grooves has an inner... The part is slidably connected to a guide slider 305, and an activated carbon plate 306 is fixedly connected between the two guide sliders 305. The limiting mechanism 5 includes two limiting seats 501, which are fixedly connected to the left and right sides of the top of the activated carbon box 301 respectively. Each limiting seat 501 has a limiting block 502 slidably connected inside. The opposite sides of the two limiting blocks 502 are movably connected to a movable screw 505, which is threadedly connected to the limiting seat 501. Each limiting seat 501 has a supporting slide rod 503 fixedly connected to the top. The supporting slide rod 503 has a sliding sleeve block 504 slidably connected to the outside of the supporting slide rod 503, which is fixedly connected to the limiting block 502.

[0043] Through the above scheme: pulling the handle 303, the movable frame 302 is pulled out from the activated carbon box 301 under the meshing action of the guide groove 308 and the movable gear 307. The activated carbon plate 306 is inserted into the movable frame 302, and the movable frame 302 is reinserted into the activated carbon box 301. The movable screw 505 is rotated, and under the action of the screw, the limiting blocks 502 on both sides are pushed to move towards each other, completing the limiting and fixing of the movable frame 302. The cooled exhaust gas enters the activated carbon box 301 for filtration through the connecting pipe 2019.

[0044] Working principle:

[0045] In actual use, firstly, by inserting the air intake pipe 102 into the connecting seat 401, the elastic force of the fixing spring 407 is used to drive the four fixing blocks 408 on the sides to move towards each other, thus completing the fixed installation of the air intake pipe 102. The toxic exhaust gas is injected into the interior of the electromagnetic coil 101 through the air intake pipe 102. After the electromagnetic coil 101 is energized, it can quickly heat up to a high temperature, which can quickly burn the toxic exhaust gas inside, thereby quickly eliminating the toxic part inside.

[0046] Secondly, by discharging the disinfected exhaust gas from the top of the spray tower 201 into the interior of the spray tower 201, the circulating pump 205 inputs spray water from the water supply pipe 206 into the first spray frame 207, and sprays it out through the high-pressure nozzle 208 to generate fine droplets, thereby rapidly cooling and breaking up the high-temperature gas mass. The spray water is then input from the connecting pipe 2013 into the second spray frame 2014 and sprayed out through the spray pipe 2015. In conjunction with the perforated plate corrugated packing 2016, the gas and liquid phases form a liquid film on the surface and carry out efficient heat and mass transfer. The spray water is then input from another connecting pipe 2013 into the third spray frame 2017 and sprayed out through the conical spray nozzle 2018, which performs a final wash on the discharged gas and acts as a liquid seal to prevent gas short circuits.

[0047] Finally, pull the handle 303 to remove the movable frame 302 from the activated carbon box 301, insert the activated carbon plate 306 into the movable frame 302, and reinsert the movable frame 302 into the activated carbon box 301. By rotating the movable screw 505, the limiting blocks 502 on both sides are pushed to move towards each other, thus completing the limiting and fixing of the movable frame 302. The cooled exhaust gas is then allowed to enter the activated carbon box 301 for filtration through the connecting pipe 2019.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
