Description

Technical Field

[0001] The invention relates to the technical field of automobile exhaust treatment, in particular to automobile exhaust treatment equipment with a filtering mechanism. Background Art

[0002] In today's modern civilization, cars have become an indispensable means of transportation for human beings. They have brought great convenience to people's lives and work, and have also developed into one of the pillars of modern material civilization. With the rapid development of the automobile industry, the continuous increase in automobile production and ownership, more and more social problems have been caused: traffic congestion has become commonplace, and the advantages of convenience, comfort and efficiency that cars should have are gradually offset by too many vehicles. The more serious problem caused by this is the air pollution it brings, that is, automobile exhaust pollution.

[0003] The exhaust we are talking about now mostly refers to automobile exhaust, that is, the exhaust gas discharged from the exhaust pipe of the car. Automobile exhaust contains hydrocarbons, carbon monoxide, nitrogen oxides and other harmful substances, some solid particles that have adverse effects on the human body, especially leaded gasoline, which is more harmful to the human body. Automobile exhaust not only smells weird, but also makes people dizzy and nauseous, affecting people's health. Automobile exhaust has been listed as one of the serious environmental pollution problems in the world. At present, the existing technology for treating automobile exhaust mostly only converts the harmful substances in the exhaust through a catalyst, but this treatment method cannot completely and thoroughly filter out the impurities in automobile exhaust. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: an automobile exhaust treatment device with a filtering mechanism, comprising: a protective shell, a positioning tube is fixedly installed on the top of the protective shell, an inner layer cover is fixedly installed inside the protective shell, and a clamping ring is fixedly installed on the surface of the inner layer cover; A flow guide component, the flow guide component is fixedly installed at the bottom of the protective shell and the inner cover, an air pipe is fixedly installed inside the flow guide component, four air pipes are arranged symmetrically with the flow guide component as the center, an assembly plate is fixedly installed on the surface of the air pipe away from the flow guide component, an air guide port is opened on the surface of the assembly plate, and the air guide port is sleeved on the outer surface of the air pipe; A catalytic component, the catalytic component is fixedly installed inside the cavity of the clamping ring, the catalytic component is provided with two groups, the two groups of catalytic components are symmetrically arranged with the clamping ring as the center, the catalytic component is attached to the inner wall of the inner cover through the clamping ring, and the surface of the catalytic component is coated with a catalyst coating; Exhaust filter, the exhaust filter is fixedly installed on the top of the inner cover, and the exhaust filter is fixedly installed inside the cavity of the positioning tube through the inner cover. When processing the exhaust of the car, the staff will install the processing equipment and connect it to the exhaust system of the car through the assembly plate, so that after the operation of the exhaust system of the car, the exhaust gas will be discharged into the air pipe along the air guide port. At this time, multiple groups of air pipes will transport the exhaust gas to the guide component. The material of the turntable installed in the air collecting pipe is relatively light. The exhaust gas discharged from the multiple groups of air pipes will blow on the turntable to make the turntable rotate in the air collecting pipe, guide the flow direction of the exhaust gas, and stir the exhaust gas to avoid the precipitation of impurities in the exhaust gas in the air collecting pipe. Then the exhaust gas in the air collecting pipe will flow into the catalytic component, and the catalytic The surface of the component is coated with a catalyst coating. Harmful gases in the exhaust gas react chemically with the catalyst coating under high temperature environment to convert the harmful gases into harmless carbon dioxide, water and nitrogen. When the converted exhaust gas passes through the corrugated ring, the densely arranged corrugated rings filter the exhaust gas and process the particles mixed in the exhaust gas. The filtered exhaust gas is transported to the exhaust filter element. At this time, the adsorbent installed around the exhaust filter element adsorbs the impurities to perform secondary treatment on the exhaust gas. The treated exhaust gas is filtered again through the filter net and discharged from the positioning tube.

[0005] Preferably, the catalytic assembly includes a wire mesh pad, a carrier is fixedly installed inside the wire mesh pad, a spiral groove is opened inside the cavity of the carrier, a corrugated ring is fixedly installed inside the spiral groove, a positioning block is fixedly installed inside the corrugated ring, the positioning block is fixedly installed at the axis of the carrier, a guide hole is opened on the surface of the corrugated ring, an outer convex ring is fixedly installed between the curved surfaces of the corrugated ring, and arc pads are fixedly installed on both sides of the outer surface of the outer convex ring. The exhaust gas is discharged into the inner cover through the gas collecting pipe, and the carrier, the positioning block and the corrugated ring surface installed in the inner cover are coated with a catalyst coating. When the exhaust gas contacts the catalyst coating under a high temperature environment, the harmful gas in the exhaust gas reacts chemically with the catalyst coating, thereby converting the harmful gas. The corrugated ring is set as a spiral structure and is compatible with the spiral groove. When the exhaust gas passes between the corrugated rings, the outer convex ring and the guide hole set on the surface of the corrugated ring affect the flow direction of the exhaust gas, so as to prolong the time that the exhaust gas stays in the corrugated ring, so as to provide time for the catalytic reaction, thereby improving the catalytic effect.

[0006] Preferably, the wire mesh pad is fixedly mounted on both sides of the outer surface of the clamping ring, the wire mesh pad is fixedly mounted on the inner wall of the inner cover through the clamping ring, the corrugated ring is set in a spiral shape, and the corrugated ring is adapted to the spiral groove. The wire mesh pad is installed inside the cavity of the inner cover to reduce vibration and fix the carrier to prevent the vibration of the car from causing the carrier to loosen and affect the catalytic reaction effect when the catalytic component is treating exhaust gas.

[0007] Preferably, the flow guide assembly includes an air collecting pipe, a positioning seat is fixedly installed on the bottom of the air collecting pipe, a turning piece is fixedly installed on the surface of the positioning seat, an extension tube is fixedly installed on the outer surface of the air collecting pipe, four extension tubes are provided, and an air guide cavity is opened inside the four extension tubes.

[0008] Preferably, the gas collecting pipe is fixedly mounted on the bottom of the protective shell and the inner cover, the extension pipes are sleeved on the outer surface of the gas pipe, and the gas guide cavity is connected to the gas pipe through the extension pipe. The tail gas flows along the gas pipe into the gas collecting pipe. Since multiple groups of gas pipes are installed around the gas collecting pipe, the tail gas discharged from the gas pipe blows the light-weight dial, causing the dial to rotate in the gas collecting pipe, thereby improving the flow and transportation of the tail gas in the gas collecting pipe. The dial is arranged below the catalytic assembly, and the tail gas stirred by the dial is dispersed more evenly when flowing into the inner cover, so as to facilitate the contact between the tail gas and the catalyst coating.

[0009] Preferably, the dial comprises a fixed shaft, a rotating rod is rotatably mounted at the axis of the fixed shaft, a collar is fixedly mounted on the top of the rotating rod, a fan-shaped piece is fixedly mounted on the outer surface of the collar, a rotating shaft is fixedly mounted on the top of the collar, a top ring is fixedly mounted on the top of the rotating shaft, an extension strip is fixedly mounted inside the top ring, and the extension strip is adapted to the fan-shaped piece. When the exhaust gas is discharged into the collecting pipe through the gas transmission pipe, the exhaust gas blows the fan-shaped piece, so that the fan-shaped piece drives the collar and the rotating rod to rotate. Since the fan-shaped piece is light in material, the extension strips installed on both sides of the top of the fan-shaped piece reinforce it to prevent the fan-shaped piece from being deformed by the exhaust gas and rubbing against the inner wall of the collecting pipe.

[0010] Preferably, the fixed shaft is fixedly installed at the center of the top of the positioning seat, four fan-shaped pieces are provided, and the four fan-shaped pieces are distributed in a circle on the outer surface of the ring.

The harmful gases in the exhaust gas treated by two layers of corrugated rings have been converted into harmless carbon dioxide, water and nitrogen. At this time, the treated exhaust gas is discharged along the gap between the corrugated rings and flows into the sleeve. The sleeve is installed on the top of the inner cover through the clamping ring. Since the caliber of the top of the inner cover is small, the discharged gas is transported into the sleeve along the side of the inner cover and contacts with the adsorbent installed around it to adsorb the impurities in the exhaust gas.

[0012] Preferably, the clamping ring is fixedly mounted on the top of the inner cover, the limiting ring is fitted with the inner wall of the inner cover, the positioning frame is configured as a semicircular structure, and the filter screen is installed in the positioning tube through the positioning frame.

[0013] Preferably, the adsorbent includes a clamping block, which is fixedly installed between the opposite surfaces of the circular ring and the limiting ring, an adsorbent sheet is clamped on the surface of the clamping block, a pressing groove is provided on the surface of the adsorbent sheet, and limiting sheets are fixedly installed on both sides of the outer surface of the clamping block. The adsorbent sheet is made of activated carbon material, and after the adsorbent sheet adsorbs impurities, the staff presses the pressing groove to remove the adsorbent sheet with the impurities attached, so as to facilitate the replacement of the adsorbent sheet and maintain the adsorption effect.

[0014] The present invention provides an automobile exhaust treatment device with a filtering mechanism, which has the following beneficial effects: 1. The automobile exhaust treatment device with a filtering mechanism discharges the exhaust gas into the inner cover through the collecting pipe. The carrier, positioning block and corrugated ring surface installed in the inner cover are coated with a catalyst coating. When the exhaust gas contacts the catalyst coating under a high temperature environment, the harmful gas in the exhaust gas reacts chemically with the catalyst coating, thereby converting the harmful gas. The corrugated ring is set to a spiral structure and is adapted to the spiral groove. When the exhaust gas passes through the corrugated rings, the outer convex ring and the guide hole set on the surface of the corrugated ring affect the flow direction of the exhaust gas, so as to prolong the time that the exhaust gas stays in the corrugated ring, so as to provide time for the catalytic reaction, thereby improving the catalytic effect.

[0015] 2. The automobile exhaust treatment device with a filtering mechanism is installed inside the cavity of the inner cover through a wire mesh pad to fix the carrier for vibration reduction to prevent the vibration of the car during the exhaust treatment of the catalytic component from causing the carrier to loosen and affect the catalytic reaction effect.

[0016] 3. The automobile exhaust treatment equipment with a filtering mechanism allows the exhaust gas to flow into the gas collecting pipe along the gas pipe. Since multiple groups of gas pipes are installed on the side of the gas collecting pipe, the exhaust gas discharged from the gas pipe blows the lighter turning member, causing the turning member to rotate in the gas collecting pipe, thereby improving the flow and transportation of the exhaust gas in the gas collecting pipe. The turning member is arranged below the catalytic component, and the exhaust gas stirred by the turning member is dispersed more evenly when flowing into the inner cover, so as to facilitate the contact between the exhaust gas and the catalyst coating.

[0017] 4. When the automobile exhaust treatment equipment with a filtering mechanism is discharged into the gas collecting pipe through the exhaust pipe, the exhaust gas blows the fan-shaped pieces, causing the fan-shaped pieces to drive the ring and the rotating rod to rotate. Since the fan-shaped pieces are made of light material, extension strips installed on both sides of the top of the fan-shaped pieces reinforce them to prevent the fan-shaped pieces from being deformed by the exhaust gas and rubbing against the inner wall of the gas collecting pipe.

[0018] 5. The automobile exhaust treatment equipment with a filtering mechanism has the harmful gases in the exhaust gas converted into harmless carbon dioxide, water and nitrogen after being treated by two layers of corrugated rings. At this time, the treated exhaust gas is discharged along the gap between the corrugated rings and flows into the sleeve. The sleeve is installed on the top of the inner cover through a clamping ring. Since the diameter of the top of the inner cover is small, the exhaust is transported along the side of the inner cover into the sleeve and contacts with the adsorbent installed around it to adsorb the impurities in the exhaust gas.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: an automobile exhaust treatment device with a filtering mechanism, comprising: a protective shell 2, a positioning tube 1 is fixedly installed on the top of the protective shell 2, an inner cover 9 is fixedly installed inside the protective shell 2, and a clamping ring 10 is fixedly installed on the surface of the inner cover 9; A flow guide component 3, the flow guide component 3 is fixedly installed at the bottom of the protective shell 2 and the inner cover 9, an air pipe 4 is fixedly installed inside the flow guide component 3, four air pipes 4 are provided, and the four air pipes 4 are symmetrically arranged with the flow guide component 3 as the center, an assembly plate 6 is fixedly installed on the surface of the air pipe 4 away from the flow guide component 3, and an air guide port 5 is opened on the surface of the assembly plate 6, and the air guide port 5 is sleeved on the outer surface of the air pipe 4; Catalytic components 7, the catalytic components 7 are fixedly installed in the cavity of the clamping ring 10, the catalytic components 7 are provided with two groups, the two groups of catalytic components 7 are symmetrically arranged with the clamping ring 10 as the center, the catalytic components 7 are attached to the inner wall of the inner cover 9 through the clamping ring 10, and the surfaces of the catalytic components 7 are coated with a catalyst coating; Exhaust filter 8, the exhaust filter 8 is fixedly mounted on the top of the inner cover 9, and the exhaust filter 8 is fixedly mounted inside the cavity of the positioning tube 1 through the inner cover 9. When processing the exhaust of the car, the staff installs the processing equipment and connects it to the exhaust system of the car through the assembly plate 6, so that after the exhaust system of the car is running, the exhaust gas is discharged into the air pipe 4 along the air guide port 5. At this time, the multiple groups of air pipes 4 transport the exhaust gas to the guide component 3. The turntable 32 installed in the collecting pipe 31 is made of a lighter material. The exhaust gas discharged from the multiple groups of air pipes 4 blows the turntable 32 to make the turntable 32 rotate in the collecting pipe 31, guide the flow direction of the exhaust gas, and stir the exhaust gas to prevent impurities in the exhaust gas from precipitating in the collecting pipe 31, and then the exhaust gas in the collecting pipe 31 flows into the catalytic component 7. The surface of the catalytic component 7 is coated with a catalyst coating. The harmful gases in the exhaust gas react chemically with the catalyst coating under high temperature environment to convert the harmful gases into harmless carbon dioxide, water and nitrogen. When the converted exhaust gas passes through the corrugated ring 74, the densely arranged corrugated ring 74 filters the exhaust gas and processes the particles mixed in the exhaust gas. The filtered exhaust gas is transported to the exhaust filter 8. At this time, the adsorption component 88 installed around the exhaust filter 8 adsorbs impurities to perform secondary treatment on the exhaust gas. The treated exhaust gas is filtered again through the filter mesh 83 and is discharged from the positioning tube 1.

[0023] The exhaust filter 8 comprises a snap ring 82, a block 84 is fixedly mounted on the top of the snap ring 82, a ring 81 is fixedly mounted on the surface of the block 84, a positioning frame 85 is fixedly mounted on the top of the ring 81, a filter screen 83 is fixedly mounted on the surface of the positioning frame 85, a sleeve 86 is fixedly mounted on the bottom of the snap ring 82, a stop ring 87 is fixedly mounted on the bottom of the sleeve 86, and an adsorbent 88 is fixedly mounted between the opposite surfaces of the ring 81 and the stop ring 87. The harmful gases in the tail gas treated by the two layers of corrugated rings 74 have been converted into harmless carbon dioxide, water and nitrogen. At this time, the treated tail gas is discharged along the gap between the corrugated rings 74 and flows into the sleeve 86. The sleeve 86 is installed on the top of the inner cover 9 through the snap ring 82. Since the caliber of the top of the inner cover 9 is small, the discharged gas is transported into the sleeve 86 along the side of the inner cover 9 and contacts the adsorbent 88 installed around it to adsorb the impurities in the tail gas.

[0024] The clamping ring 82 is fixedly mounted on the top of the inner cover 9 , the limiting ring 87 is fitted with the inner wall of the inner cover 9 , the positioning frame 85 is configured as a semicircular structure, and the filter screen 83 is installed in the positioning tube 1 through the positioning frame 85 .

[0025] The adsorbent 88 includes a clamping block 881, which is fixedly installed between the opposite surfaces of the ring 81 and the limiting ring 87. An adsorbing sheet 883 is clamped on the surface of the clamping block 881, and a pressing groove 884 is opened on the surface of the adsorbing sheet 883. The limiting sheets 882 are fixedly installed on both sides of the outer surface of the clamping block 881. The adsorbing sheet 883 is set to be made of activated carbon. After the adsorbing sheet 883 adsorbs impurities, the staff presses the pressing groove 884 to remove the adsorbing sheet 883 with impurities attached, so as to facilitate the replacement of the adsorbing sheet 883 and maintain the adsorption effect.

[0026] The second embodiment is based on the first embodiment. Figures 7 and 8 As shown, the catalytic component 7 includes a steel mesh pad 71, a carrier 72 is fixedly installed inside the steel mesh pad 71, a spiral groove 73 is opened inside the cavity of the carrier 72, a corrugated ring 74 is fixedly installed inside the spiral groove 73, a positioning block 75 is fixedly installed inside the corrugated ring 74, the positioning block 75 is fixedly installed at the axis center of the carrier 72, a guide hole 77 is opened on the surface of the corrugated ring 74, an outer convex ring 76 is fixedly installed between the curved surfaces of the corrugated ring 74, and arc pads 78 are fixedly installed on both sides of the outer surface of the outer convex ring 76. The exhaust gas is discharged into the inner cover 9 through the collecting pipe 31. The surfaces of the carrier 72, the positioning block 75 and the corrugated ring 74 installed in the inner cover 9 are coated with a catalyst coating. When the exhaust gas contacts the catalyst coating under high temperature, the harmful gas in the exhaust gas reacts chemically with the catalyst coating, thereby converting the harmful gas. The corrugated ring 74 is set to a spiral structure and is compatible with the spiral groove 73. When the exhaust gas passes through the corrugated rings 74, the outer convex ring 76 and the guide hole 77 set on the surface of the corrugated ring 74 affect the flow direction of the exhaust gas, so as to prolong the time that the exhaust gas stays in the corrugated ring 74, so as to provide time for the catalytic reaction, thereby improving the catalytic effect.

[0027] The wire mesh pad 71 is fixedly mounted on both sides of the outer surface of the clamping ring 10, and the wire mesh pad 71 is fixedly mounted on the inner wall of the inner cover 9 through the clamping ring 10. The corrugated ring 74 is set in a spiral shape, and the corrugated ring 74 is adapted to the spiral groove 73. The wire mesh pad 71 is installed inside the cavity of the inner cover 9 to reduce vibration and fix the carrier 72 to prevent the vibration of the car from causing the carrier 72 to loosen and affect the catalytic reaction effect when the catalyst assembly 7 is treating the exhaust gas.

[0028] The third embodiment is based on the first and second embodiments. Figures 9 to 11As shown, the air guide component 3 includes an air collecting pipe 31, a positioning seat 35 is fixedly installed on the bottom of the air collecting pipe 31, a turning member 32 is fixedly installed on the surface of the positioning seat 35, and an extension pipe 33 is fixedly installed on the outer surface of the air collecting pipe 31. Four extension pipes 33 are provided, and an air guide cavity 34 is opened inside the four extension pipes 33.

[0029] The gas collecting pipe 31 is fixedly mounted at the bottom of the protective shell 2 and the inner cover 9, and the extension pipes 33 are sleeved on the outer surface of the gas pipe 4. The gas guide cavity 34 is connected to the gas pipe 4 through the extension pipe 33. The tail gas flows into the gas collecting pipe 31 along the gas pipe 4. Since multiple groups of gas pipes 4 are installed on the periphery of the gas collecting pipe 31, the tail gas discharged from the gas pipe 4 blows the light-weight dial 32, so that the dial 32 rotates in the gas collecting pipe 31, thereby improving the flow and transportation of the tail gas in the gas collecting pipe 31. The dial 32 is arranged below the catalytic assembly 7. The tail gas stirred by the dial 32 is dispersed more evenly when flowing into the inner cover 9, so that the tail gas can contact the catalyst coating.

[0030] The dial member 32 includes a fixed shaft 327, a rotating rod 326 is rotatably mounted at the axis of the fixed shaft 327, a collar 325 is fixedly mounted on the top of the rotating rod 326, a fan-shaped piece 321 is fixedly mounted on the outer surface of the collar 325, a rotating shaft 324 is fixedly mounted on the top of the collar 325, a top ring 322 is fixedly mounted on the top of the rotating shaft 324, an extension bar 323 is fixedly mounted inside the top ring 322, and the extension bar 323 is adapted to the fan-shaped piece 321. When the exhaust gas is discharged into the gas collecting pipe 31 through the gas transmission pipe 4, the exhaust gas blows the fan-shaped piece 321, so that the fan-shaped piece 321 drives the collar 325 and the rotating rod 326 to rotate. Since the fan-shaped piece 321 is made of light material, the extension bars 323 installed on both sides of the top of the fan-shaped piece 321 reinforce it to prevent the fan-shaped piece 321 from being deformed by the exhaust gas and rubbing against the inner wall of the gas collecting pipe 31.

[0031] The fixed shaft 327 is fixedly installed at the center of the top of the positioning seat 35, and four fan-shaped pieces 321 are provided. The four fan-shaped pieces 321 are distributed in a circle on the outer surface of the ring 325, and the extension strip 323 is set in a bent shape. The extension strip 323 is clamped on both sides of the outer surface of the fan-shaped piece 321.

[0032] When in use, when treating the exhaust of a car, the staff installs the treatment equipment and connects it to the exhaust system of the car through the assembly plate 6, so that after the exhaust system of the car is running, the exhaust gas is discharged into the air pipe 4 along the air guide port 5. At this time, the multiple groups of air pipes 4 transport the exhaust gas to the guide component 3. The turntable 32 installed in the collecting pipe 31 is made of a lighter material. The exhaust gas discharged from the multiple groups of air pipes 4 blows the turntable 32 to make the turntable 32 rotate in the collecting pipe 31, guide the flow direction of the exhaust gas, and stir the exhaust gas to prevent impurities in the exhaust gas from settling in the collecting pipe 31. Then the exhaust gas in the collecting pipe 31 is directed to the catalytic component 7. The surface of the catalytic component 7 is coated with a catalyst coating, and the harmful gases in the exhaust gas react chemically with the catalyst coating under high temperature environment to convert the harmful gases into harmless carbon dioxide, water and nitrogen. When the converted exhaust gas passes through the corrugated ring 74, the densely arranged corrugated ring 74 filters the exhaust gas and processes the particles mixed in the exhaust gas. The filtered exhaust gas is transported to the exhaust filter 8. At this time, the adsorption component 88 installed around the exhaust filter 8 adsorbs impurities to perform secondary treatment on the exhaust gas. The treated exhaust gas is filtered again through the filter mesh 83 and is discharged from the positioning tube 1.

[0033] The tail gas flows along the gas delivery pipe 4 to the gas collecting pipe 31. Since multiple groups of gas delivery pipes 4 are installed around the gas collecting pipe 31, the tail gas discharged from the gas delivery pipe 4 blows the light-weight dial 32, causing the dial 32 to rotate in the gas collecting pipe 31, thereby improving the flow and transportation of the tail gas in the gas collecting pipe 31. The dial 32 is arranged below the catalytic assembly 7. The tail gas stirred by the dial 32 is dispersed more evenly when flowing into the inner cover 9, so that the tail gas can contact the catalyst coating. When the tail gas is discharged into the gas collecting pipe 31 through the gas delivery pipe 4, the tail gas blows the fan-shaped piece 321, causing the fan-shaped piece 321 to drive the ring 325 and the rotating rod 326 to rotate. Since the fan-shaped piece 321 is light-weight, the extension strips 323 installed on both sides of the top of the fan-shaped piece 321 reinforce it to prevent the fan-shaped piece 321 from being deformed by the exhaust gas and rubbing against the inner wall of the gas collecting pipe 31.

[0034] The exhaust gas is discharged to the inner cover 9 through the gas collecting pipe 31. The surfaces of the carrier 72, the positioning block 75 and the corrugated ring 74 installed in the inner cover 9 are coated with a catalyst coating. When the exhaust gas contacts the catalyst coating under high temperature, the harmful gas in the exhaust gas reacts chemically with the catalyst coating, thereby converting the harmful gas. The corrugated ring 74 is set to a spiral structure and is adapted to the spiral groove 73. When the exhaust gas passes through the corrugated rings 74, the outer convex ring 76 and the guide hole 77 set on the surface of the corrugated ring 74 affect the flow direction of the exhaust gas to extend the time that the exhaust gas stays in the corrugated ring 74, so as to provide time for the catalytic reaction, thereby improving the catalytic effect. The wire mesh pad 71 is installed inside the cavity of the inner cover 9 to reduce vibration and fix the carrier 72 to prevent the vibration of the car from causing the carrier 72 to loosen and affect the catalytic reaction effect when the catalytic component 7 is treating the exhaust gas.

[0035] The harmful gases in the tail gas treated by the two layers of corrugated rings 74 have been converted into harmless carbon dioxide, water and nitrogen. At this time, the treated tail gas is discharged along the gap between the corrugated rings 74 and flows into the sleeve 86. The sleeve 86 is installed on the top of the inner cover 9 through the clamp ring 82. Since the diameter of the top of the inner cover 9 is small, the exhaust is transported along the side of the inner cover 9 into the sleeve 86 and contacts the adsorbent 88 installed around it to adsorb the impurities in the tail gas. The adsorption sheet 883 is set to be made of activated carbon. After the impurities are adsorbed on the adsorption sheet 883, the staff presses the pressing groove 884 to remove the adsorption sheet 883 with impurities attached, so as to facilitate the replacement of the adsorption sheet 883 and maintain the adsorption effect.
