[0003] The patent with application number CN202223028402.1 mentions "a noise-reducing three-way catalytic converter structure". The patent uses the mesh plate on the connecting plate for preliminary dispersion and floats it to the fan blades, thereby driving the fan blades to rotate on their own. In this way, the fan blades can further disperse the automobile exhaust gas, making it more evenly contact with the ceramic carrier. After being filtered by the ceramic carrier, it can also be discharged more evenly from the air outlet, which can effectively reduce noise and thus improve the use effect of the three-way catalytic converter structure.

[0004] However, when the current three-way catalytic converter is used, the particulate matter in the automobile exhaust contacts and decelerates the catalyst, resulting in the deposition of particulate matter. In addition, the existing equipment is not equipped with self-cleaning components, resulting in the accumulation of particulate matter on the surface of the catalyst during long-term use, resulting in a reduction in the contact area between the exhaust gas and the catalyst, which greatly affects the catalytic effect.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. A series-reverse multi-cleaning component is provided, which realizes catalytic reaction by contacting the exhaust gas with the catalytic treatment block and the honeycomb series through-hole. The exhaust gas is dispersed through the honeycomb series through-hole and the series-gas light pipe, and the exhaust gas in the series-gas light pipe is accelerated by the accelerating series-pass bucket. The inclined external discharge is achieved by coordinating the guide exhaust frame and the directional guide hole. The inclined external discharge airflow pushes the guide operation box and the series-gas light pipe to rotate slowly, driving the flexible bonding sheet to clean the slag on the inner wall of the honeycomb series through-hole, and cooperates with the continuous flow of airflow to take away the raised particle debris, reducing the occurrence of the situation where the catalytic effect is affected by the large-scale deposition of particles. The airflow is diverted by the internal cleaning component and the catalytic contact area is increased, thereby improving the catalytic reaction rate and effect.

The high-speed fan, high-speed air intake pipe, circulating cleaning pipe, circulating exhaust cleaning pipe and linked solenoid valve cooperate with each other to drive the circulation of air in and out of the replacement sleeve. The closed mesh cover, inlet screen plate, purification mesh cage and circulating cleaning pipe are used to inject clean air. The storage net box is used to intercept air and particulate matter. The residual particulate matter is taken away by the internal circulation of the airflow, realizing the self-cleaning of the interior of the catalyst and ensuring the cleanliness of the contact surface. Through internal airflow acceleration, exhaust guidance, continuous intake rotation, slag scraping, internal and external restricted circulation and particle interception and collection, the problem of the existing technology that no cleaning components are provided, resulting in the deposition of particulate matter in automobile exhaust, covering the surface of the catalyst and affecting the catalytic effect, is effectively solved. By scraping and cleaning, high-speed exhaust discharge and rapid circulation and discharge of internal clean air, the surface of the catalyst is cleaned stably and continuously, ensuring the contact area of ​​the catalytic reaction and improving the catalytic effect and efficiency during continuous use.

[0016] 2. A connecting protection component is provided, which restricts the positioning of the inlet and outlet communication pipes by means of multi-threaded combination rods, compression nuts, anti-skid elastic sheets, combined connecting frames and connecting buffer sleeves. The screw is lifted and pressed with elastic gaskets, and the connection tightness of the combined connecting frame and the inlet and outlet communication pipes is adjusted in conjunction with compression screws and clamping buffer pads. The installation position and connection points of the catalyst are adjusted according to the position of the automobile exhaust pipe to ensure the convenience of installation alignment and combined connection. The overall inlet and outlet replacement sleeve shell is protected by an anti-puncture restriction sleeve and an impact-resistant blocking plate, and the connection points are detected in conjunction with anti-skid elastic sheets and connecting buffer sleeves to reduce the large impact force on the catalyst caused by chassis scratches, stone flying and large shaking of the car, thereby achieving its stable protection treatment and improving its stability and safety in use.

[0017] In summary, through the cooperation of the series-reverse multi-cleaning components and the continuous protection components, the impact resistance is improved through external buffer protection and sleeve protection, and the internal airflow self-cleaning treatment and external pressurized airflow circulation slag cleaning treatment are combined to ensure the contact area during long-term internal use, improve the catalytic effect, achieve stable operation of the catalyst, and avoid the occurrence of reduced catalytic effect or equipment damage due to internal and external environmental influences.

[0023] The working principle and use process of the present invention are as follows: When installing the three-way catalytic converter, the staff connects the multi-threaded combination rod 308 to the position of the car chassis through threads, and places a press nut 310 and an anti-skid elastic sheet 311 on the side end of the multi-threaded combination rod 308 in sequence, and then fits the combination connecting frame 305 with the multi-threaded combination rod 308 so that the side end of the combination connecting frame 305 fits with the side end of the connection buffer sleeve 309. At this time, the second anti-skid elastic sheet 311 and the press nut 310 are placed on the side end of the multi-threaded combination rod 308 in sequence. The fixed installation of the combined connecting frame 305 is achieved through the two-way pressing and clamping at the top and bottom ends, and the positions of the combined connecting frame 305, the inlet and outlet communication pipe 211 and the overall inlet and outlet replacement sleeve 1 are adjusted through the lifting and correction of the upper and lower positions. The clamping screw 306 drives the clamping buffer 307 to clamp and protect the inlet and outlet communication pipe 211, ensuring the rapid alignment of the combined flange 304 and the automobile exhaust pipe flange. The combined flange 304 is combined with the automobile exhaust pipe flange by connection to achieve the installation of the three-way catalytic converter. When the three-way catalytic converter is in use, when the car is just started, the exhaust gas heat cannot reach the optimal catalytic temperature of the three-way catalytic converter. The exhaust gas is heated by the auxiliary electric heating sleeve 212 in the inlet and outlet serial pipe 211 to increase the exhaust gas temperature, so that the exhaust gas can maintain a constant temperature and the optimal catalytic state when it contacts the catalytic treatment block 202. After a period of startup, the auxiliary electric heating sleeve 212 is turned off. During the continuous discharge of the automobile exhaust gas, the exhaust gas flows along the inlet and outlet serial pipe 211 into the position of the heat preservation buffer sleeve 201 on the inner side of the overall inlet and outlet replacement sleeve 1, and When the tail gas contacts the catalytic treatment block 202, the tail gas will be dispersed by the honeycomb through-holes 204, and the tail gas contact area will be increased through the honeycomb through-holes 204. When the tail gas enters the inside of the honeycomb through-holes 204, the tail gas will be dispersed by the light-gas stringing pipe 206. Part of the tail gas will flow between the honeycomb through-holes 204 and the light-gas stringing pipe 206, and the remaining tail gas will flow along the light-gas stringing pipe 206. When the tail gas flows to the accelerating string bucket 208, the air will enter through the large holes and the air will exit through the small holes, which will increase the air flow rate. The high-speed tail gas will pass through After acceleration, it flows to the position of the guide operation box 205. At this time, the guide exhaust frame 210 is used to guide the air outward. The high-speed airflow is discharged along the inclined directional guide hole 209. The inclined airflow pushes the guide operation box 205 and the string air light pipe 206 to rotate along the slot positioning plate 203. At this time, the flexible bonding sheet 207 rotates with the string air light pipe 206, and the flexible bonding sheet 207 is used to continuously scrape the inner wall of the honeycomb string hole 204, so that during the catalytic process, the fine particles carried in the exhaust gas are lifted up, reducing the particle residue and avoiding Due to the large amount of residual particles, the contact area is reduced, and the catalytic efficiency is reduced. The airflow is used to push the process, so that the components can operate automatically, improving the synchronization and effect of the overall process. The rotation and contact cooperate with each other to increase the catalytic contact area and improve the catalytic treatment effect. During the driving process of the car, the anti-puncture restriction sleeve 301 and the impact-resistant blocking plate 303 protect the outer shell of the entire entry and exit replacement sleeve 1, reducing the significant damage to the exterior of the entire entry and exit replacement sleeve 1 caused by scratches on the car chassis or flying stones, thereby ensuring its safety in use. When the car stops running, the high-speed fan 223 is powered by the car battery, and the high-speed fan 223 and the high-speed air intake pipe 222 extract the air from the separate collection box 214 and discharge it outside. At this time, the circulating cleaning pipe 216 is used to extract the air in the entire in-and-out replacement sleeve 1, and the in-and-out communication pipe 211 is closed by the linked solenoid valve 315, so that a low-pressure environment is formed inside the entire in-and-out replacement sleeve 1. The external air enters the purification net cage 220 position in the separate collection box 214 through the closed mesh cover 217 and the inlet blocking plate 218, and is adsorbed and purified by the activated carbon adsorbent in the purification net cage 220 and then injected into the entire in-and-out replacement sleeve 1 along the circulating cleaning pipe 215, realizing external exhaust and external air intake, realizing the circulation of the airflow in the entire in-and-out replacement sleeve 1, and the residual particulate matter remaining in the entire in-and-out replacement sleeve 1 is driven to be discharged through the circulating airflow, realizing the purification treatment of the catalytic treatment block 202 inside the entire in-and-out replacement sleeve 1, and the discharged particulate matter is intercepted by the storage net box 225 to realize centralized collection and treatment; When performing automobile maintenance, the staff rotates the closed mesh cover 217 to remove the purification mesh cage 220 from the top of the isolation load-bearing plate 219, and inserts the new purification mesh cage 220 into the top of the isolation load-bearing plate 219 in the sub-position collection box 214 to achieve quick replacement, opens the closed sealing cover 221, pulls out the storage mesh box 225, and inserts the new storage mesh box 225 into the inner side of the sub-position collection box 214, and magnetically combines the magnetic positioning plate 224 and the connecting magnetic plate 226 to achieve the storage mesh cage 225. 5 is quickly replaced, which is convenient for quick maintenance and processing.
