[0010] Step two: when the screw rod driving motor drives the spiral ring to move up and down reciprocatingly, the up and down reciprocating movement of the spiral ring pushes the connecting sliding rod to move downward, the downward movement of the connecting sliding rod drives the activated carbon plate to move downward, the up and down reciprocating movement of the activated carbon plate can more evenly contact the waste gas flow, the contact time and contact area of the waste gas and the surface of the activated carbon are increased, which helps to improve the adsorption efficiency of the harmful substances in the waste gas;

[0011] Step 3: As the activated carbon plate moves upward, it drives the slip ring to move upward. The upward movement of the slip ring pushes the short rod to move upward, which in turn pushes the sealing slide plate to move upward. The upward movement of the sealing slide plate opens the air outlet, allowing water vapor to be released intermittently through the water vapor generating equipment.

[0012] Step 4: Steam permeates into the pores of activated carbon, helping to desorb adsorbed organic matter or pollutants, improving the regeneration efficiency of the activated carbon plate, eliminating the need for frequent replacement of the activated carbon plate, and improving work efficiency.

[0013] According to the above technical solution, the air intake control device includes a sliding plate, a fixed frame, a ball bearing, and a sealing plate. When the activated carbon plate moves downward, it pushes the ball bearing downward.

A water tank is provided on the outer wall of the purification tower. A spray head is fixedly installed on the side of the water tank close to the purification tower. A circular plate is fixedly installed on the top of the fixing plate. By spraying adsorbent through the spray head, impurities in the exhaust gas can be effectively adsorbed. At the same time, when the sealing plate moves upward, it will drive the fixing plate to move upward, and the fixing plate will drive the circular plate to move upward. The circular plate moves upward to the bottom of the spray head.

[0015] According to the above technical solution, a second spring is provided between the sliding plate and the purification tower. The second spring automatically drives the sliding plate to reset. The circular plate is located below the spray head.

[0016] According to the above technical solution, the anti-water ingress device plate includes a guide tube, a connecting rod, a sealing baffle, a sealing connecting rod, and a ring.

[0018] According to the above technical solution, a No. 3 spring is provided between the sealing link and the ring. The sealing link is reset by the elastic force of the No. 3 spring. A No. 1 torsion spring is provided between the connecting frame and the rotating cover plate. The rotating cover plate is reset by the elastic force of the No. 1 torsion spring.

[0019] This invention provides an environmentally friendly dyeing and printing waste gas purification and treatment device and process. It possesses the following features:

[0020] Beneficial effects:

[0021] (1) In this invention, pollutants can be evenly distributed on the surface of the activated carbon plate by rotating it, so that the adsorption capacity of the activated carbon can be continuously and optimized. At the same time, when the screw drives the motor to rotate, it will drive the spiral ring to move up and down. The up and down movement of the spiral ring will push the connecting slide rod to move downward. The downward movement of the connecting slide rod will drive the activated carbon plate to move downward. Through the up and down movement of the activated carbon plate, it can contact the exhaust gas flow more evenly, increasing the contact time and contact area between the exhaust gas and the activated carbon surface, which helps to improve the adsorption efficiency of harmful substances in the exhaust gas.

[0022] (2) In this invention, the upward movement of the activated carbon plate will drive the slip ring to move upward, the upward movement of the slip ring will push the short rod to move upward, the upward movement of the short rod will push the sealing plate to move upward, and the upward movement of the sealing plate will open the air outlet, and water vapor will be released intermittently through the water vapor generation device. The steam will penetrate into the pores of the activated carbon, helping to desorb the adsorbed organic matter or pollutants, improving the regeneration efficiency of the activated carbon plate, eliminating the need for frequent replacement of the activated carbon plate, and improving work efficiency.

[0023] (3) In this invention, when the activated carbon plate moves downward, it will push the ball bearing, the fixed frame, the sliding plate and the sealing plate downward. When the sealing plate moves downward, it will reseal the air inlet. By intermittently introducing waste gas, the continuous operation of the equipment can be avoided, and unnecessary energy consumption can be reduced. Especially when the waste gas concentration is low or fluctuates greatly, the intermittent working mode helps to improve energy efficiency, prevent the activated carbon from becoming saturated quickly under high load, and provide it with more time to recover. By having the circular plate in close contact with the spray head, the liquid sprayed by the spray head hits the circular plate and splashes, increasing the spray range of the adsorbent and improving the adsorption effect.

[0024] (4) In this invention, the sealing rod moves upward to contact the ring and seals the ring, which increases the time the adsorbent stays inside the purification tower and improves the adsorption effect of the adsorbent. When the sealing rod moves downward, the ring will reopen, allowing the adsorbent accumulated inside the purification tower to be discharged, preventing the water level from rising and causing liquid to enter the air inlet, which would affect the entry of waste gas. At the same time, the rotating baffle rotates downward to block the air inlet, preventing the adsorbent from splashing into the air inlet when it is sprayed, which would cause a large amount of liquid to accumulate inside the air inlet, affecting the subsequent waste gas intake and the waste gas treatment effect.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 - Figure 8 One embodiment of the present invention is: an environmentally friendly dyeing and printing waste gas purification and treatment device, comprising: a purification tower 1, an emission device 2, the emission device 2 being fixedly installed on the surface of the purification tower 1; an air inlet 3, the air inlet 3 being fixedly installed on the side of the purification tower 1 away from the emission device 2; a fixed bracket 4, the fixed bracket 4 being fixedly installed on the inner wall of the purification tower 1; a screw drive motor 5 is provided on the surface of the fixed bracket 4, a groove is provided at the output end of the screw drive motor 5, a sliding block 6 is slidably installed on the inner wall of the groove, a fixed rod 7 is fixedly installed at the bottom of the sliding block 6, an activated carbon plate 8 is provided at the bottom of the fixed rod 7, a connecting slide rod 9 is fixedly installed at the top of the activated carbon plate 8, and a spiral ring 10 is slidably installed at the top of the connecting slide rod 9; the screw drive motor 5 is used to drive the spiral ring 10 to reciprocate up and down. The spiral ring 10 is threaded onto the output end of the screw drive motor 5. A slide rod 101 is fixedly installed at the bottom of the fixed bracket 4, and the slide rod 101 passes through the surface of the spiral ring 10. A steam generating device 11 is provided on the outer wall of the purification tower 1. An outlet 12 is provided on the side of the steam generating device 11 near the purification tower 1. A sealing slide plate 13 is slidably installed on the inner wall of the purification tower 1. A short rod 14 is fixedly installed at the bottom of the sealing slide plate 13. An activated carbon plate 8 is used to push the short rod 14 to move upward. The purification tower 1 is equipped with a device for controlling the air intake and a device for preventing water ingress. The reciprocating motion of the activated carbon plate 8 can make more uniform contact with the exhaust gas flow, increasing the contact time and contact area between the exhaust gas and the activated carbon surface, which helps to improve the adsorption efficiency of harmful substances in the exhaust gas.

[0036] A first spring is installed between the purification tower 1 and the sealing slide plate 13. When the activated carbon plate 8 moves downward, the sealing slide plate 13 loses its push and will reset under the elastic force of the first spring. A slip ring is installed on the top of the activated carbon plate 8, and the short rod 14 is pushed upward through the slip ring.

[0037] In this embodiment, the waste gas generated during printing and dyeing is introduced into the purification tower 1 through the air inlet 3. The activated carbon plate 8 inside the purification tower 1 absorbs the harmful substances in the waste gas, thereby improving the purification of the waste gas. At the same time, the lead screw drive motor 5 is started during use. The rotation of the lead screw drive motor 5 will drive the sliding block 6 to rotate. The rotation of the sliding block 6 will drive the fixed rod 7 to rotate. The rotation of the fixed rod 7 will drive the activated carbon plate 8 to rotate.

[0038] By rotating the activated carbon plate 8, pollutants can be evenly distributed on its surface, allowing the adsorption capacity of the activated carbon to be continuously and optimally utilized. At the same time, when the screw drive motor 5 rotates, it will drive the spiral ring 10 to move up and down reciprocally. The up and down reciprocating motion of the spiral ring 10 will push the connecting slide rod 9 to move downward. The downward movement of the connecting slide rod 9 will drive the activated carbon plate 8 to move downward. Through the up and down reciprocating motion of the activated carbon plate 8, it can more evenly contact the exhaust gas flow, increasing the contact time and contact area between the exhaust gas and the activated carbon surface, which helps to improve the adsorption efficiency of harmful substances in the exhaust gas.

[0039] Simultaneously, as the activated carbon plate 8 moves upward, it drives the slip ring to move upward. The upward movement of the slip ring pushes the short rod 14 upward, which in turn pushes the sealing slide plate 13 upward. The upward movement of the sealing slide plate 13 opens the air outlet 12, allowing water vapor to be released intermittently through the steam generation device 11. This steam permeates into the pores of the activated carbon, helping to desorb adsorbed organic matter or pollutants, thus improving the regeneration efficiency of the activated carbon plate 8. This eliminates the need for frequent replacement of the activated carbon plate 8 and improves work efficiency.

[0040] Please see Figure 1 - Figure 8 Based on the above embodiments, in another embodiment of the present invention, the air intake control device includes a sliding plate 151, a fixed frame 152, a ball bearing 153, and a sealing plate 154. The sliding plate 151 is slidably installed on the inner wall of the purification tower 1, the fixed frame 152 is fixedly installed on the side of the sliding plate 151 away from the purification tower 1, the ball bearing 153 is disposed inside the fixed frame 152, and the sealing plate 154 is fixedly installed at the bottom of the sliding plate 151. By intermittently introducing exhaust gas, continuous operation of the equipment can be avoided, reducing unnecessary energy consumption. Especially when the exhaust gas concentration is low or fluctuates greatly, the intermittent working mode helps to improve energy efficiency, prevents activated carbon from becoming saturated quickly under high load, and provides it with more time to recover.

[0041] A fixing plate 155 is fixedly installed on the side of the sealing plate 154 away from the purification tower 1. A water tank 156 is provided on the outer wall of the purification tower 1. A spray head 157 is fixedly installed on the side of the water tank 156 close to the purification tower 1. A circular plate 158 is fixedly installed on the top of the fixing plate 155. The circular plate 158 is in close contact with the spray head 157, so that the liquid sprayed by the spray head 157 hits the circular plate 158 and splashes, thereby increasing the spray range of the adsorbent and improving the adsorption effect.

[0042] A second spring is installed between the sliding plate 151 and the purification tower 1. The sliding plate 151 is automatically reset by the elastic force of the second spring. The circular plate 158 is located below the spray head 157.

[0043] In this embodiment, when the activated carbon plate 8 moves downward, it pushes the ball bearing 153 downward. When the activated carbon plate 8 moves upward, the ball bearing 153 loses its compression, and the elastic force of the second spring drives the sliding plate 151 and the fixed frame 152 upward. The upward movement of the sliding plate 151 drives the sealing plate 154 upward. The upward movement of the sealing plate 154 disengages from the air inlet, allowing the exhaust gas to enter the purification tower 1. When the activated carbon plate 8 moves downward, it pushes the ball bearing 153, the fixed frame 152, the sliding plate 151, and the sealing plate 154 downward. The downward movement of the sealing plate 154 re-seals the air inlet 3. By intermittently introducing exhaust gas, continuous operation of the equipment can be avoided, reducing unnecessary energy consumption. Especially when the exhaust gas concentration is low or fluctuates greatly, the intermittent working mode helps to improve energy efficiency, prevents the activated carbon from becoming saturated quickly under high load, and provides it with more time to recover.

[0044] Simultaneously, the adsorbent sprayed through the spray head 157 can effectively adsorb impurities in the exhaust gas. When the sealing plate 154 moves upward, it will drive the fixing plate 155 to move upward. The upward movement of the fixing plate 155 will drive the circular plate 158 to move upward. When the circular plate 158 moves upward to the bottom of the spray head 157, the circular plate 158 will come into close contact with the spray head 157, causing the liquid sprayed by the spray head 157 to hit the circular plate 158 and splash, thereby increasing the spray range of the adsorbent and improving the adsorption effect.

[0045] The water-proof device plate includes a guide tube 161, a connecting rod 162, a sealing baffle 163, a sealing connecting rod 164, and a ring 165. The guide tube 161 is fixedly installed at the bottom of the inner wall of the purification tower 1, the connecting rod 162 is fixedly installed at the bottom of the fixing plate 155, the ring 165 is fixedly installed on the inner wall of the guide tube 161, the sealing connecting rod 164 slides through the ring 165, and the sealing baffle 163 is fixedly installed at the top of the sealing connecting rod 164. The sealing connecting rod 164 moves upward and contacts the ring 165 to seal the ring 165, thereby increasing the time that the adsorbent stays inside the purification tower 1 and improving the adsorption effect of the adsorbent.

[0046] A connecting frame 166 is fixedly installed on the inner wall of the purification tower 1. A rotating baffle 167 is rotatably installed on the inner wall of the connecting frame 166. A connecting push rod 168 is fixedly installed on the surface of the sealing plate 154. A short plate 169 is fixedly installed on the surface of the rotating baffle 167 to prevent the adsorbent from splashing into the air inlet 3 during spraying, which would cause a large amount of liquid to accumulate inside the air inlet 3, affecting the subsequent intake of waste gas and the waste gas treatment effect.

[0047] A No. 3 spring is provided between the sealing link 164 and the ring 165. The No. 3 spring's own elastic force drives the sealing link 164 to reset. A No. 1 torsion spring is provided between the connecting frame 166 and the rotating cover 167. The No. 1 torsion spring's own elastic force drives the rotating cover 167 to reset.

[0048] A treatment process for an environmentally friendly dyeing and printing waste gas purification and treatment device includes the following steps:

[0049] Step 1: By introducing the waste gas generated from printing and dyeing into the purification tower 1 through the air inlet 3, the activated carbon plate 8 inside the purification tower 1 absorbs the harmful substances in the waste gas, thereby improving the purification of the waste gas. At the same time, the lead screw drive motor 5 is started during use. The rotation of the lead screw drive motor 5 drives the sliding block 6 to rotate, the rotation of the sliding block 6 drives the fixed rod 7 to rotate, and the rotation of the fixed rod 7 drives the activated carbon plate 8 to rotate. By rotating the activated carbon plate 8, pollutants can be evenly distributed on its surface, so that the adsorption capacity of the activated carbon can be continuously and optimally exerted.

[0050] Step 2: When the lead screw drives the motor 5 to rotate, it drives the spiral ring 10 to move up and down reciprocally. The reciprocating motion of the spiral ring 10 pushes the connecting slide rod 9 to move downward. The downward movement of the connecting slide rod 9 drives the activated carbon plate 8 to move downward. The reciprocating motion of the activated carbon plate 8 can make more uniform contact with the exhaust gas flow, increasing the contact time and contact area between the exhaust gas and the activated carbon surface. This helps to improve the adsorption efficiency of harmful substances in the exhaust gas.

[0051] Step 3: As the activated carbon plate 8 moves upward, it drives the slip ring to move upward. The upward movement of the slip ring pushes the short rod 14 to move upward. The upward movement of the short rod 14 pushes the sealing slide plate 13 to move upward. The upward movement of the sealing slide plate 13 opens the air outlet 12, and water vapor is intermittently released through the water vapor generating device 11.

[0052] Step 4: Steam permeates into the pores of activated carbon, helping to desorb adsorbed organic matter or pollutants, improving the regeneration efficiency of activated carbon plate 8, eliminating the need for frequent replacement of activated carbon plate 8, and improving work efficiency.

[0053] The upward movement of the fixed plate 155 causes the connecting rod 162 to move upward. The upward movement of the connecting rod 162 causes the sealing baffle 163 and the sealing connecting rod 164 to move upward. The upward movement of the sealing connecting rod 164 causes it to contact the ring 165 and seal the ring 165, increasing the time that the adsorbent stays inside the purification tower 1 and improving the adsorption effect of the adsorbent. When the sealing connecting rod 164 moves downward, it will cause the ring 165 to reopen, allowing the adsorbent accumulated inside the purification tower 1 to be discharged, preventing the water level from rising and causing liquid to enter the air inlet 3, which would affect the entry of exhaust gas.

[0054] Simultaneously, when the sealing plate 154 moves upward, it will drive the connecting push rod 168 to move upward. The upward movement of the connecting push rod 168 will push the short plate 169 to rotate upward. The upward rotation of the short plate 169 will drive the rotating baffle 167 to rotate downward. The downward rotation of the rotating baffle 167 will block the air inlet 3, preventing the adsorbent from splashing into the air inlet 3 during spraying, which would cause a large amount of liquid to accumulate inside the air inlet 3, affecting the subsequent intake of waste gas and the waste gas treatment effect.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

6. A treatment process for an environmentally friendly dyeing and printing waste gas purification and treatment device, using the environmentally friendly dyeing and printing waste gas purification and treatment device as described in claim 5, characterized in that... Includes the following steps: Step 1: By introducing the waste gas generated from printing and dyeing into the purification tower (1) through the air inlet (3), the harmful substances in the waste gas are absorbed by the activated carbon plate (8) inside the purification tower (1), thereby improving the purification of the waste gas. At the same time, the screw drive motor (5) is started during use. The screw drive motor (5) rotates and drives the sliding block (6) to rotate. The sliding block (6) rotates and drives the fixed rod (7) to rotate. The fixed rod (7) rotates and drives the activated carbon plate (8) to rotate. By rotating the activated carbon plate (8), pollutants can be evenly distributed on its surface, so that the adsorption capacity of the activated carbon can be continuously and optimally exerted. Step 2: When the screw drive motor (5) rotates, it drives the spiral ring (10) to move up and down. The spiral ring (10) moves up and down and pushes the connecting slide (9) to move downward. The connecting slide (9) moves downward and drives the activated carbon plate (8) to move downward. The reciprocating motion of the activated carbon plate (8) can make more uniform contact with the exhaust gas flow, increasing the contact time and contact area between the exhaust gas and the activated carbon surface. This helps to improve the adsorption efficiency of harmful substances in the exhaust gas. Step 3: As the activated carbon plate (8) moves upward, it drives the slip ring to move upward. The upward movement of the slip ring pushes the short rod (14) to move upward. The upward movement of the short rod (14) pushes the sealing slide plate (13) to move upward. The upward movement of the sealing slide plate (13) opens the air outlet (12), and water vapor is intermittently released through the water vapor generating device (11). Step 4: By permeating the pores of the activated carbon with steam, the adsorbed organic matter or pollutants are desorbed, improving the regeneration efficiency of the activated carbon plate (8), eliminating the need for frequent replacement of the activated carbon plate (8), and improving work efficiency.
