The first embodiment is as follows:

referring to fig. 1-2, an automobile exhaust preliminary treatment receiver tube, includes tail gas receiver tube 1, and spout 2 has been seted up to the lateral wall of tail gas receiver tube 1, and sealed sliding connection has sliding plug 5 in the spout 2, installs the drive arrangement of drive sliding plug 5 round trip movement in the spout 2, and exhaust hole 21 has been seted up to the interior bottom of spout 2, and exhaust hole 21 can make things convenient for sliding plug 5 round trip movement unhindered. The side wall of the sliding plug 5 is fixedly connected with a telescopic air bag 6, the tail gas receiving pipe 1 is fixedly connected with a one-way liquid discharge pipe 7 and a one-way liquid return pipe 8 which are communicated with the telescopic air bag 6, and a liquid storage barrel 9 is jointly communicated between the one-way liquid discharge pipe 7 and the one-way liquid return pipe 8.

It should be noted that the one-way liquid discharge pipe 7 only allows the coolant to flow into the liquid storage cylinder 9 from the telescopic airbag 6, the one-way liquid return pipe 8 only allows the coolant to flow back into the telescopic airbag 6 from the liquid storage cylinder 9, and the liquid storage cylinder 9 is made of an elastic material and can expand and contract, so that the coolant can flow smoothly, and in addition, as shown in fig. 2, the one-way liquid discharge pipe 7 is embedded in the tail gas receiving pipe 1 in a surrounding manner, so that the heat dissipation area is greatly increased, and the heat dissipation efficiency is improved. And the liquid storage cylinder 9 sets up outside the car, can be at the vehicle in-process that traveles, and high velocity air constantly blows liquid storage cylinder 9, can promote the cooling liquid cooling in the liquid storage cylinder 9 to can continuously carry out cooling treatment to tail gas.

The driving device comprises an air inlet pipe 3 and an air outlet pipe 4 which are communicated with the inside of the chute 2, a normally open type electromagnetic valve 31 and a normally closed type electromagnetic valve 41 are respectively arranged in the air inlet pipe 3 and the air outlet pipe 4, the normally open type electromagnetic valve 31 and the normally closed type electromagnetic valve 41 are connected in series in the same power supply circuit, and the normally open type electromagnetic valve 31 is controlled by a circuit to be opened and closed at regular time, so that when the normally open type electromagnetic valve 31 is electrified, the normally closed type electromagnetic valve 41 is also electrified, and at the moment, the normally open type electromagnetic valve 31 is closed; when the normally open type solenoid valve 31 is de-energized, the normally closed type solenoid valve 41 is also de-energized, and at this time, the normally open type solenoid valve 31 is opened and the normally closed type solenoid valve 41 is closed.

As shown in fig. 1, the exhaust gas flows in the exhaust gas receiving pipe 1 along the arrow direction, when the normally open type electromagnetic valve 31 is opened and the normally closed type electromagnetic valve 41 is closed, part of the exhaust gas flows into the chute 2 along the air inlet pipe 3 and pushes the sliding plug 5 to move right and compress the retractable air bag 6, after a period of time, the normally open type electromagnetic valve 31 is closed and the normally closed type electromagnetic valve 41 is opened, the retractable air bag 6 is opened under the action of the elastic force of the retractable air bag 6 and pushes the sliding plug 5 to move right, the exhaust gas in the chute 2 can be discharged into the exhaust gas receiving pipe 1 again, and when the normally open type electromagnetic valve 31 is opened and the normally closed type electromagnetic valve 41 is closed next time, the sliding. So can be at open and close in-process of normally open solenoid valve 31 and normally closed solenoid valve 41, make sliding plug 5 round trip movement in spout 2 to make flexible gasbag 6 stretch out and draw back constantly, thereby under the one-way current limiting effect of one-way fluid-discharge tube 7 and one-way liquid return pipe 8, force the coolant liquid unidirectional circulation flow in the pipeline, can be quick distribute away the heat of tail gas, greatly reduced tail gas's temperature, cause the damage in order to avoid high temperature gas to following clarifier or muffler.

Example two:

referring to fig. 3-4, different from the first embodiment, the sliding plug 5 is made of iron, the bottom of the exhaust receiving pipe 1 is fixedly connected with a plurality of supporting pipes 11, and the upper ends of the plurality of supporting pipes 11 are fixedly connected with a wind shield 10 together, it should be noted that the wind shield 10 can support the notched cylindrical shape shown in fig. 4 to facilitate installation and use, and in addition, a collecting box can be arranged at the discharge end of the supporting pipe 11 to collect the impurities discharged from the supporting pipe 11, and only the collecting box needs to be cleaned periodically.

The inner bottom of the windshield 10 is provided with bristles 101, the windshield 10 is rotatably connected with the glass cylinder 12, and the glass cylinder 12 rotates in the windshield 10 through the damping rotating shaft, so that a certain frictional resistance exists between the glass cylinder 12 and the windshield 10, and the glass cylinder 12 can be stabilized in the windshield 10. The permanent magnet 13 is connected in the glass cylinder 12 in a sliding manner, the chemical fiber plate 131 is fixedly connected to the upper end of the permanent magnet 13, and the chemical fiber plate 131 is arranged at the upper end of the permanent magnet 13, so that the static electricity generated by the glass cylinder 12 can be only located on one side of the upper end of the glass cylinder 12.

In this embodiment, the conventional automobile exhaust purifier usually only treats harmful gases such as CO, HC, NOX, etc. in the exhaust, and the automobile exhaust often contains incombustible fine solid impurities such as dust, etc., and the purifier has a limited effect on treating such pollutants, which is also one of the reasons for increasing the PM2.5 content in the air, so the second design example is to pre-purify the exhaust.

In the process that the iron sliding plug 5 moves back and forth in the sliding chute 2, the permanent magnet 13 in the glass cylinder 12 is attracted by magnetic force and continuously moves back and forth, the chemical fiber plate 131 above the permanent magnet 13 can continuously rub the inner wall of the glass cylinder 12 and generate static electricity on the glass cylinder 12, fine solid impurities can be adsorbed on the surface of the glass cylinder 12, the tail gas is subjected to pre-purification treatment, and the purification rate of the automobile tail gas is greatly improved.

Due to the windshield 10, the exhaust gas contacts only one side of the glass cylinder 12, so that the fine solid impurities are attached to only one side of the glass cylinder 12, as shown in fig. 4. When the small solid impurities on the glass cylinder 12 are accumulated to a certain amount, one side of the glass cylinder 12 is heavier and overcomes the frictional resistance to rotate clockwise, and when the glass cylinder 12 rotates, the brush bristles 101 at the bottom in the windshield 10 can scrape the adsorbed small solid impurities off and discharge the small solid impurities from the support tube 11, so that the glass cylinder 12 can keep clean and can continuously adsorb the small solid impurities in the tail gas.
