The inner cavities of the two synchronous wheels 5 are respectively fixedly connected to conveying wheels 7, and when one of the conveying wheels 7 rotates, it can drive one of the synchronous wheels 5. The step wheel 5 rotates, and then one of the synchronous wheels 5 rotates to drive the synchronous belt 6 to drive the other synchronous wheel 5 to rotate, and then the other synchronous wheel 5 drives the other conveying wheel 7 to rotate. The conveying wheel 7 is arranged in the inner cavity of the separation tank 1, and the first air intake pipe 2 is located on the side of the conveying wheel 7. When the carbon black exhaust gas enters the interior of the separation tank 1 through the first air intake pipe 2, the exhaust gas enters from the first air intake pipe 2 at a speed of 15-25m / s, and relies on the fluid inertia to naturally form a double helix vortex to drive the conveying wheel 7 to rotate. The double conveying wheels 7 are used to transport the particulate matter in the exhaust gas to the interior of the discharge pipe 201.

When the charcoal exhaust gas enters the interior of the separation tank 1 through the first air intake pipe 2, the exhaust gas enters from the first air intake pipe 2 at a speed of 15-25m / s. Relying on the fluid inertia, a double spiral vortex is naturally formed to drive the conveying wheel 7 to rotate. The double conveying wheel 7 is used to convey the particulate matter in the exhaust gas to the interior of the discharge pipe 201. The exhaust gas after the particles are separated is conveyed to the interior of the secondary separation component through the first conveying pipe 13. When the particles inside the discharge pipe 201 are stored to a certain amount, the rotary valve 3 is started, and the rotary valve 3 is used to convey the particles inside the discharge pipe 201 to the interior of the collection box 4.

The first and second layers of the honeycomb electrode plate 17 charge and adsorb the large particles of carbon black in the carbon black. The third and fourth layers generate plasma active particles OH / O3 to oxidize and decompose the strong oxidizing substances generated by dielectric barrier discharge, deeply degrading the pollutants in the carbon black waste gas. The waste gas after decomposition drifts to the upper part of the inner cavity of the separation tower 14 and is detected by the detection sensor 20. When it is detected that the waste gas degradation amount is low, the second power is automatically turned off. Move the valve 24 and open the first electric valve 23, and the exhaust gas is transported to the bottom of the separation tower 14 again through the circulation pipe 22, and the staff increases the current output to the connector 18, and uses the honeycomb electrode plate 17 to decompose the exhaust gas again. When the detection sensor 20 detects that the exhaust gas is qualified, the first electric valve 23 is closed, and the second electric valve 24 is opened to transport the gas to the inside of the third air intake pipe 30. When the exhaust gas is decomposed and filtered through the honeycomb electrode plate 17, the delivery pump 27 is started.

An ultraviolet LED 32 is provided on the side of the top of the inner cavity of the separation box 29 close to the titanium mesh 31. The ultraviolet LED 32 emits ultraviolet light to the surface of the titanium mesh 31, so that the ultraviolet light reacts with the graphene composite coating to produce electron-hole pairs, thereby generating strong oxidizing free radicals to decompose organic matter on the surface of the carbon black. The upper part of the ultraviolet LED 32 is fixedly connected to the inner wall of the separation box 29 through a connecting seat.

[0044] The front side of the separation box 29 is connected to the air outlet pipe 33, and the two sides of the inner cavity of the separation box 29 are fixedly connected to the limiting frames 34.

The exhaust gas is delivered to the inside of the third air inlet pipe 30 through the second air inlet pipe 15, and the exhaust gas is decomposed by the graphene composite coating on the surface of the titanium mesh 31. The decomposed exhaust gas is discharged to the outside of the device through the exhaust pipe 33. When there is exhaust gas residue attached to the surface of the titanium mesh 31, the water pump 46 can be started.The water pump 46 drives the flow pipe 41 to extract the water from the water collection box 42 and transport it to the inside of the water pipe 40. The water is transported from the water pipe 40 to the inside of the flushing rack 35, and the drive motor 38 is started. The drive motor 38 drives the screw rod 39 to rotate. When the screw rod 39 rotates, it can drive the drive plate 37 to move up and down. When the drive plate 37 moves, it can drive the flushing rack 35 fixed on the surface to move. The flushing rack 35 then transports the water to the inside of the flushing head 36, and the flushing head 36 flushes the waste gas impurities remaining on the surface of the titanium mesh 31. The direction of movement of the flushing rack 35 is limited by the limit frame 34. The flushed water is transported to the outlet trough through the guide plate 44 and discharged to the outside of the device. The water collection box 42 can collect rainwater and use the barrier net 43 on the surface to block the debris on the rainwater. The inclined surface setting allows the blocked debris to slide to the outside of the device.
