The method of heavy load regeneration is simple, but the automobile diesel engine rarely works under the working condition in actual use, the power performance and the economical efficiency of the diesel engine are greatly reduced in the regeneration process due to throttling, the thermal load of parts such as a cylinder head, a piston, a valve and the like is increased due to throttling, and the service life of the diesel engine is adversely affected; when the combustion product metal oxide of the catalytic regeneration fuel additive flows through the filter along with the exhaust gas, a part of the combustion product metal oxide can be deposited, and the additive metal combustion product accumulated on the filter body can block the pores of the filter body, thereby shortening the service life of the filter. If the sediment is too much, the backpressure rises, and the dynamic property and the economical efficiency of the diesel engine are influenced, and the problem can be solved only by replacing the filter body regularly at present. The metal dust released into the atmosphere causes secondary pollution. The problems of the catalyst such as resistance to poisoning, thermal stability, secondary pollution and the like are not really solved at present; in order to ensure the successful regeneration of the filter body, the regeneration burner is required to have the characteristics of reliable ignition, complete combustion, uniform flame distribution and the like, and if the ignition fails, fuel is deposited on the filter body to cause secondary deposition and pollution and easily cause deflagration. Incomplete combustion can cause smoke generation in exhaust during regeneration and secondary pollution; the requirement of electric heating regeneration on a vehicle power supply is high, the problem of high power consumption needs to be solved in the vehicle process, and the manufacturing process of the crystalline SiC is complex and high in cost.

Thus, each method has significant drawbacks that result in an overall less than optimal result.

For the convenience of understanding the technical solutions of the present invention, the following detailed description will be made on the working principle or the operation mode of the present invention in the practical process.

In practical application, when in use, diesel engine exhaust enters the filtering regeneration bin 1 through the connecting pipeline 3, in the filtering stage, the low-voltage heating element 17 does not work, gas passes through the filtering device 20, the gas exhausted by the diesel engine is filtered by utilizing the large-hole filter screen 24 in the outer filter shell 21 to match with the core filter core 25, and is exhausted into the atmosphere, when the filter body needs to be regenerated, the low-voltage heating element 17 is electrified, under the heating of the low-voltage heating element 17, the infrared radiator 18 generates radiation waves, the radiation energy of the radiation waves heats soot, the soot on the end of the filter body close to the infrared radiator 18 in the radial cross section is simultaneously ignited, when the combustion cross section reaches the other end face of the filter body, the soot in the filter body is completely combusted, the regeneration is finished, and the connecting pipeline 3 can be inserted into the inner cavity 6 in the connecting shell 5 by utilizing the effect of the connecting structure 4, utilize the effect of spacing baffle 7 to carry on spacingly, simultaneously, utilize threaded rod 10 to link together screw hole 9 and connecting thread groove 11, make connecting tube 3 carry out fixed mounting, and simultaneously, utilize the effect of installation limit structure 19, can utilize the effect of outer slider 26 of crossing on the filter shell 21, install spout 28 on the cooperation mounting panel 27, make outer filter shell 21 install between mounting panel 27, make things convenient for its installation and change, such device simple structure, high durability and convenient use, can improve the electric energy utilization of infrared radiation heating soot greatly, the regeneration time is short, the easy optimal control of regeneration process, reach regeneration efficiency, regeneration temperature distribution, the regeneration time, several indexes of regeneration energy consumption are optimized simultaneously, make things convenient for filter equipment 20's change and connecting tube 3's installation fixed simultaneously.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
