As shown in FIG. 1, a connecting pipe 3 is connected to the exhaust gas discharge end 112 of the first purification treatment apparatus 1 of the present invention. The connecting pipe 3 is provided with an alkaline liquid atomizing nozzle 4. The exhaust gas passes through the first purification treatment apparatus 1 and is filtered. After the primary purification treatment is performed, the exhaust gas is sent to the connecting pipe 3.

Example 1
Please refer to FIG. 1 and FIG. One end of the connecting pipe 3 of the present invention is connected to the second purification treatment device 2. The second purification treatment apparatus 2 includes an exhaust gas transport unit 21 connected to the connection pipe 3 and an exhaust gas purification treatment unit 23 connected to the exhaust gas transport unit 21. Among them, the exhaust gas transport unit 21 includes a plurality of transport pipes 211, a first fixed plate 212, and a second fixed plate 213. The transport pipe 211 can be bent many times, thereby increasing its length and surface area, and increasing the contact time with air. Since the transport pipe 211 is a pipe member made of a copper material, it has excellent heat conduction and heat dissipation performance. The first fixing plate 212 and the second fixing plate 213 are circular plate members, each provided with a plurality of through holes. The first fixing plate 212 is attached to the exhaust gas discharge port of the connecting pipe 3, and both ends of the transport pipe 211 pass through the through holes of the first fixing plate 212 and the second fixing plate 213. An appropriate distance is maintained between the assembled transport pipes 211. Furthermore, the outer surface of the transport pipe 211 can be coated with a heat radiation paint (for example, boron nitride) in order to enhance the heat absorption effect and the heat radiation effect.

As shown in FIG. 2, the exhaust gas purification processing unit 23 includes a head portion 231 including a hollow portion 2310 and a pipe 232 connected to the head portion 231, and the head portion 231 is connected to a second fixing plate 213. The The head portion 231 is provided with a purified gas generator 24. The purified gas generator 24 sends the generated gas purification substance into the cavity portion 2310 and mixes it with the exhaust gas. A catalytic ceramic filter element 25 having a plurality of holes for removing fine suspended particles is provided inside the pipe 232 connected to the head portion 231.

(Example 2)
The second embodiment of the second purification treatment apparatus 2 shown in FIG. 3 has the same structure as that of the first embodiment of FIG. 2, but in the embodiment of FIG. 3, each transport pipe 211 of the exhaust gas transport unit 21 is spiral. There is a difference in that an appropriate distance is maintained between the transport pipes 211 and a heat radiating space is formed. The function of purifying exhaust gas and the function of removing suspended particles are the same as in the embodiment of FIG.

In the present invention, in the normal operation state, the combustion system 113 of the first purification treatment apparatus 1 does not operate, and the exhaust gas discharged from the car engine passes directly through the combustion system 113 and the filtration system 17. After the contaminants contained in the exhaust gas are filtered by the direct type noble metal medium ceramic filter element 171 and the honeycomb type noble metal medium ceramic filter element 172 of the filtration system 17, the exhaust gas is sent to the connecting pipe 3. At this time, the alkaline liquid atomizing apparatus 4 ejects an appropriate amount of atomized alkaline liquid (for example, a vegetable alkaline liquid, a chemically synthesized alkaline liquid, etc.) into the connecting pipe 3 in a timely manner and in the exhaust gas. Then, the exhaust gas is further sent to the second purification treatment apparatus 2. When the exhaust gas exhausted from the first purification treatment apparatus 1 is in a smooth state, if the back pressure of the exhaust gas in the combustion system 113 is detected by the first pressure sensor 15A to be a predetermined value or less, the overall control system The fire ejection device 12 is not activated. Then, after being used for a certain period of time, when the filtration system 17 is clogged with carbon and the gas discharge is not smooth, the second pressure sensor 15B senses that the back pressure in the combustion system has increased, A signal is sent to the microcomputer control system 14, and at the same time, the control system sends an operation command to the pump fuel box 123, and fuel is sent from the fuel pipe 122 to the nozzle 121 by the pressurized pump of the pump fuel box 123 that has been activated. The fuel atomized and ejected and further atomized by the ignition device 13 is ignited, burned, and heated. This high temperature is immediately transmitted to the filtration system 17, and the carbon adhering to the direct type precious metal medium ceramic filter element 171 and the honeycomb type precious metal medium ceramic filter element 172 is burned and removed. When a certain amount of accumulated carbon is removed, the filtration system 17 returns to a smooth state in which no carbon is clogged. At this time, the first pressure sensor 15A senses that the back pressure in the combustion system 113 has dropped below a predetermined value, and sends a signal to the microcomputer control system 14. The control system stops the operation of the fire ejection device 12. A command is sent and the operation of the fire ejection device 12 is stopped, and the exhaust gas discharged from the diesel engine passes through the filtration system 17 and is filtered and discharged. By repeating the above operation, accumulated carbon can be efficiently removed.

Then, after the exhaust gas passes through the connecting pipe 3, is neutralized by the atomized alkaline liquid, and sent to the second purification treatment device 2, the exhaust gas passes through each transport pipe 211 of the exhaust gas transport unit 21. To do. The number of the transport pipes 211 is large, and since they are bent several times or are spiral and long in length, the surface area is large, and a certain amount of heat in the exhaust gas is absorbed by the air. In addition, since the airflow generated when the vehicle travels also releases heat, the exhaust gas that has entered the cavity 2310 of the head portion 231 falls to an appropriate temperature. At this time, the gas purification substance (for example, ozone or urea) ejected from the purification gas generator 24 is mixed with the exhaust gas in the low temperature environment of the cavity 2310, and the toxic substance contained in the exhaust gas is purified. The purified exhaust gas is sent to the pipe 232, passes through the catalytic ceramic filter element 25 having a plurality of holes, removes fine suspended particles, and is finally discharged into the atmosphere.
