Specific Embodiment

[0034] The following combines the accompanying drawings to describe in detail a specific embodiment of the present invention. However, it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0035] As Figures 1 to 8 shown, an injection - type plasma waste gas treatment device provided by an embodiment of the present invention includes an intake pipe 1, a filtration component 2, a plasma treatment component 3, and an exhaust pipe 4 communicating with the plasma treatment component 3. The filtration component 2 is communicated with the intake pipe 1 and the plasma treatment component 3. That is, the waste gas first enters the filtration component 2 through the intake pipe 1, and the filtered waste gas then enters the plasma treatment component 3 for treatment and finally is discharged through the exhaust pipe 4. Through the filtration component 2, the filtration of organic impurities and fine particulate matters can be realized, the wear of the plasma treatment component 3 can be reduced, and thus the service life of the plasma treatment component 3 can be extended;

[0036] The filtration component 2 of this embodiment includes a filter cartridge 5, a spiral - shaped filtration channel 6 opened in the filter cartridge 5, and multiple groups of filtration structures distributed along the spiral - shaped filtration channel 6. At least two groups of filtration structures are distributed along the axial direction of the filter cartridge 5. The filtration structure includes two relatively arranged filter plates 7. In the initial state, the two form a larger filter plate 7. The filter plate 7 of this embodiment is an activated carbon plate;

[0037] An installation cavity 8 is opened at the center of the filter cartridge 5, and a plurality of installation grooves 9 are opened on the outer wall of the filter cartridge 5. The installation cavity 8 and any one of the installation grooves 9 are both communicated with the filtration channel 6 through a plurality of relief grooves 10 that cooperate with the plurality of filter plates 7. In addition, a rubber sleeve (not shown in the figure) is installed in the relief groove 10. The rubber sleeve has a notch that is in interference fit with the filter plate 7, so as to reduce or prevent the leakage of waste gas. Connecting pieces for connecting with the filter plate 7 are arranged in both the installation cavity 8 and the installation groove 9;

[0038] The connecting member includes a mounting frame 11, a connecting shaft 12 hinged on the mounting frame 11, and a plurality of connecting frames 13, wherein the plurality of connecting frames 13 are fixedly connected to the connecting shaft 12, and a slot matching with the filter plate 7 is provided on the connecting frame 13, so that the filter plate 7 can be installed on the connecting frame 13, and the mounting frame 11 is fixedly connected to the filter cartridge 5 by bolts. Due to the difference in the structure of the mounting cavity 8 and the mounting groove 9, the structural form of the mounting frame 11 in the mounting cavity 8 is different from that of the mounting frame 11 in the mounting groove 9;

[0039] The two filter plates 7 of the filtering structure are respectively connected to the connecting piece located in the installation cavity 8 and the connecting piece located in the installation groove 9. For the convenience of distinction, the two are respectively called the cavity plate 14 and the groove plate 15. In order to improve the service life of the filter plate 7, both sides of the filter plate 7 of this embodiment have an activated carbon layer. Therefore, a driving mechanism is also provided on the filter cartridge 5 of this embodiment. The driving mechanism is used to adjust the angle of the cavity plate 14 and the groove plate 15. In the initial state, the cavity plate 14 and the groove plate 15 are in the same plane. After a long time of use, the activated carbon layer on the side of the cavity plate 14 and the groove plate 15 facing the exhaust gas is in a nearly saturated state. At this time, the driving mechanism is used to adjust the cavity plate 14 or the groove plate 15. The angle of the plate 15, specifically, the driving mechanism can simultaneously drive one of the filter plates 7 in the multiple filter structures to swing, that is, the driving mechanism can synchronously drive the cavity plates 14 of the multiple filter structures to rotate a certain angle (20°-40°), at which time the slot plate 15 remains in its original position, and after the exhaust gas enters the filter assembly 2, the slot plate 15 will guide a part of the exhaust gas to the side of the cavity plate 14 that originally faces away from the exhaust gas (i.e., the back side), thereby completing the adsorption of some impurities, and subsequently the cavity plate 14 is reset and the slot plate 15 is rotated a certain angle by the driving mechanism, and the cavity plate 14 guides a part of the exhaust gas to the side of the slot plate 15 that originally faces away from the exhaust gas, thereby completing the adsorption of some impurities;

[0040] The driving mechanism of this embodiment includes a transmission ring 21, a plurality of gears 1 22, a plurality of gears 23, and a motor 26 for driving the transmission ring 21 to rotate. The plurality of gears 1 22 are connected to the plurality of connecting shafts 12 located in the mounting cavity 8, and specifically, the plurality of gears 23 are connected to the plurality of connecting shafts 12 located in the plurality of mounting grooves 9. A square connecting block 24 is connected to the bottom of the connecting shaft 12. A concave limiting plate 25 matching the connecting block is provided at the center of the gears 1 22 and the gears 2 23. A plurality of tooth portions are provided at intervals on the inner and outer sides of the transmission ring 21. The inner tooth portion and the outer tooth portion are respectively meshed and connected with the gears 1 22 and the gears 2 23.

[0041] The output end of the motor 26 may be connected to a gear 3 (not shown), which is meshed and connected with the transmission ring 21. Of course, the gear 3 may also be connected to the transmission ring 21 through other transmission structures.

[0042] In some other embodiments, a guide member is provided in the installation cavity 8. The guide member has a guide channel that cooperates with the mounting bracket 11. This design facilitates the operator to assemble the filter structure and its connecting members from the installation cavity 8 to the designated position.
