[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] The adsorption module includes a first servo motor 2 fixedly mounted on the surface of the carbon box 11, a flap roller 21 is fixedly mounted on the output shaft of the first servo motor 2, and the flap roller 21 is movably mounted inside the carbon box 11. A heating chamber 22 is fixedly mounted on the side of the carbon box 11 away from the second air duct 13 and is connected to the heating chamber 22. A blocking door 23 is hinged at the connection between the carbon box 11 and the heating chamber 22.

[0039] The regeneration module includes a first return spring 24, which is fixedly mounted at the bottom of the inner cavity of the heating chamber 22, a follower 25 is fixedly mounted on the top of the heating chamber 22, and an ejection plate 26 is fixedly mounted on the top of the follower 25, and the ejection plate 26 is adapted to the inner cavity of the heating chamber 22 and is in active contact with the inner cavity of the heating chamber 22;

[0040] The shape of the follower 25 near the carbon box 11 is an inclined surface, and a driving member 27 is attached to the inclined surface of the follower 25. A power member 28 is fixedly installed on one side of the driving member 27. The power member 28 passes through the heating chamber 22 and extends to the outside of the heating chamber 22. An elastic column 29 is fixedly installed on one side of the driving member 27. One end of the elastic column 29 away from the driving member 27 is fixedly connected to the inner cavity wall of the heating chamber 22.

[0041] A first rotating wheel 210 is fixedly sleeved on the outer surface of the first servo motor 2, a first transmission belt 211 is transmission-connected to the outer surface of the first rotating wheel 210, a second rotating wheel 212 is transmission-connected to the side of the first transmission belt 211 away from the first rotating wheel 210, and a trigger 213 is fixedly installed in the middle of the second rotating wheel 212;

[0042] A cooling box 214 is fixedly installed on the side of the heating bin 22 away from the charcoal box 11, a fixing plate 215 is fixedly installed on the side of the heating bin 22 away from the charcoal box 11, an electric push rod 216 is fixedly installed in the middle of the fixing plate 215, a feeding plate 217 is fixedly installed on the output shaft of the electric push rod 216, the feeding plate 217 is inside the cooling box 214 and is in active contact with the cooling box 214, a material guide bin 220 is fixedly installed on the upper side of the cooling box 214, and one end of the material guide bin 220 away from the cooling box 214 is fixedly installed inside the charcoal box 11;

[0043] A fan 218 is fixedly installed on one side of the heating chamber 22 close to the cooling box 214, and an air duct 219 is fixedly installed on the surface of the heating chamber 22, one end of the air duct 219 is located at the air outlet of the fan 218, and the other end is located above the ejection plate 26;

[0044] The ends of the triggering member 213 and the power member 28 are both arc-shaped, and the moving stroke of the ejection plate 26 is a straight line distance from a to b;

[0045] Specifically, when in use, the user first needs to pass the exhaust gas into the inner cavity of the carbon box 11 through the first air duct 12, so that the activated carbon in the inner cavity of the carbon box 11 can adsorb the exhaust gas. During the activated carbon adsorption process, the first servo motor 2 can be started every one to two hours, so that the first servo motor 2 drives the flap roller 21 to flip counterclockwise, which can flip the activated carbon in the inner cavity of the carbon box 11, so that different activated carbon particles and surfaces are in contact with the exhaust gas first, avoiding the problem that the activated carbon cannot move and is easily saturated, and can effectively improve the adsorption effect;

[0046] On the other hand, when the flap roller 21 flips counterclockwise, it can make the activated carbon squeeze the baffle 23, so that the baffle 23 opens. At this time, the activated carbon enters the inner cavity of the heating chamber 22, and the heating chamber 22 is started to heat the activated carbon for thermal regeneration of the activated carbon. When the flap roller 21 flips counterclockwise, it drives the first rotating wheel 210 to rotate counterclockwise, and drives the first transmission belt 211, so that the first transmission belt 211 drives the second rotating wheel 212 to rotate counterclockwise. The second rotating wheel 212 can drive the triggering member 213 to rotate counterclockwise. When the triggering member 213 rotates counterclockwise, it gradually contacts the power member 28, so that the power member 28 moves and gradually squeezes the driven member 25. At this time, the first return spring 24 is squeezed, and the ejection plate 26 gradually drops from b to a. This is the initial working state of the ejection plate 26. Figure 4 As shown;

[0047] When the activated carbon is regenerated after one to two hours, the first servo motor 2 is started again. When the first servo motor 2 is started, the first rotating wheel 210 rotates counterclockwise again, driving the first transmission belt 211, so that the first transmission belt 211 drives the second rotating wheel 212 to rotate, and the second rotating wheel 212 can drive the trigger 213 to rotate;

[0048] When the trigger 213 rotates, the power member 28 is no longer limited. At this time, the elastic column 29 pulls the driving member 27 to move, and the follower 25, under the elastic force provided by the first return spring 24, drives the ejection plate 26 to move upward quickly, that is, quickly moves upward from position a to position b, so that the regenerated activated carbon on the upper surface of the ejection plate 26 can be ejected into the inner cavity of the cooling box 214, and the fan 218 is started to cool the activated carbon. After the activated carbon is cooled, the electric push rod 216 is started to drive the feeding plate 217 to rise, so that it passes through the guide bin 220 and enters the carbon box 11 to achieve recycling;

[0049] It should be noted that, because the present invention aims to regenerate the activated carbon in contact with the exhaust gas introduction direction, in order to reduce the amount of un-adsorbed activated carbon entering the heating chamber 22, the optimal rotation angle of the flap roller 21 and the actuator 213 in the present invention is 90 degrees each time.

[0050] During manufacturing, the air outlet of the fan 218 can be directed toward the inside of the cooling box 214 to cool the activated carbon. At the same time, the wind resistance can be used to prevent the activated carbon from entering the reheating chamber 22 when it rises. Part of the air can be introduced into the top of the ejection plate 26 through the air duct 219 to assist the regeneration of the activated carbon.

[0051] Embodiment 2: A spray assembly is provided on the base 1, and the spray assembly includes an air suction bin 3 fixedly mounted on the upper surface of the base 1, the air suction bin 3 is connected to the second air guide pipe 13, and a spray head 31 is fixedly mounted on the top of the inner cavity of the air suction bin 3;

[0052] A second servo motor 37 is fixedly mounted on the surface of the air suction bin 3, a third rotating wheel 32 is fixedly mounted on the outer surface of the output shaft of the second servo motor 37, a second transmission belt 33 is transmission-connected to the outer surface of the third rotating wheel 32, a fourth rotating wheel 34 is transmission-connected to the side of the second transmission belt 33 away from the third rotating wheel 32, an air guide bin 36 is fixedly mounted on the upper surface of the air suction bin 3, a rotating shaft is fixedly mounted on the middle of the fourth rotating wheel 34, and the rotating shaft is movably mounted on the surface of the air guide bin 36;

[0053] The surface of the rotating shaft of the fourth rotating wheel 34 is fixedly mounted with a fan blade 35 , the surface of the air guide bin 36 is provided with a through groove, and the air guide bin 36 is communicated with the air suction bin 3 .

[0054] On the basis of Example 1, the gas adsorbed by the activated carbon will enter the inner cavity of the air suction bin 3 through the second air guide pipe 13, and the gas can be sprayed and purified by the nozzle 31. By starting the second servo motor 37, the third rotating wheel 32 can be driven to rotate, so that the third rotating wheel 32 drives the second transmission belt 33, and the second transmission belt 33 can drive the fourth rotating wheel 34 to rotate, so that the fourth rotating wheel 34 drives the fan blades 35 to rotate;

[0055] When the fan blades 35 rotate, airflow is generated and flows into the inner cavity of the air intake bin 3 from the air guide bin 36, thereby accelerating the flow rate of the water mist sprayed from the nozzle 31, and then increasing the contact frequency between the water mist and the gas, making the spray purification effect more excellent. It should be noted that a one-way airflow channel must be provided in the air guide bin 36 to prevent the exhaust gas from diffusing. Secondly, a speed change device can be provided between the fourth impeller 34 and the fan blades 35 to increase the rotation speed of the fan blades 35.

[0056] Embodiment 3: A water curtain assembly is provided on the air suction bin 3, and the water curtain assembly includes support columns 4. The number of support columns 4 is four, and they are respectively fixedly installed at the four corners of the bottom of the inner cavity on one side of the air suction bin 3. A limit block 41 is fixedly installed on the top of the support column 4. A second return spring 42 is sleeved on the outer surface of the support column 4. An extrusion plate 43 is movably installed on the outer surface of the support column 4.

[0057] An eccentric wheel 44 is fixedly installed in the middle of the third rotating wheel 32, and the eccentric wheel 44 is located below the extrusion plate 43. A baffle plate 45 is fixedly installed in the inner cavity of the air suction bin 3, a spray pipe 47 is fixedly installed in the middle of the baffle plate 45, a one-way valve 46 is fixedly installed on the side of the baffle plate 45, a spray hole 48 is opened on the surface of the spray pipe 47, a water curtain member 49 is fixedly installed on the top of the spray pipe 47, and an air outlet pipe 410 is fixedly installed on the upper surface of the air suction bin 3 away from the air guide bin 36;

[0058] The diameter of the limit block 41 is larger than the diameter of the support column 4, the bottom end of the second return spring 42 is fixedly connected to the bottom of the inner cavity of the air suction bin 3, and the top end of the second return spring 42 is fixedly connected to the bottom of the extrusion plate 43;

[0059] The spray pipe 47 is in the shape of a cone that is narrow at the top and wide at the bottom, and the water curtain member 49 is in the shape of an umbrella, and a through groove is provided on the surface;

[0060] A first water pipe 5 is fixedly installed on one side of the air intake bin 3, and the first water pipe 5 is below the extrusion plate 43. A filter box 51 is fixedly installed on the end of the first water pipe 5 away from the air intake bin 3, and the filter box 51 is fixedly installed above the base 1. A second water pipe 52 is fixedly installed inside the filter box 51, and an evaporator 53 is fixedly installed on the end of the second water pipe 52 away from the filter box 51. The evaporator 53 is fixedly installed on the surface of the heating bin 22, and the air outlet of the evaporator 53 is connected to the heating bin 22.

[0061] On the basis of Example 2, when the water after spraying purification will enter between the baffle plate 45 and the extrusion plate 43 through the one-way valve 46, when the third runner 32 rotates, it will drive the eccentric wheel 44 to rotate. Under the elastic support provided by the second return spring 42, the extrusion plate 43 will continue to move up and down, thereby squeezing the water between the baffle plate 45 and the extrusion plate 43 into the inner cavity of the spray pipe 47. Since the spray pipe 47 is a cone with a narrow top and a wide bottom, when the water enters the top of the spray pipe 47, the flow rate will not decay too much. At this time, part of the water will be sprayed out from the spray hole 48 to purify the gas again. In this way, the water purification can be fully recycled;

[0062] Another part of the water flow will flow out from the top of the spray pipe 47, flow on the surface of the water curtain member 49, and form a water curtain on its surface, while the gas will pass through the grooves on the surface of the water curtain member 49, ensuring that the water can fully purify the gas, further improving the effect of spray purification. In order to ensure the continuity of the water curtain, some small wing plates can be set on the grooves on the surface of the water curtain member 49 to block the water flow and prevent the water flow from running away quickly. When the water flow rate is reduced, the water curtain can be sustained with continuous water supply;

[0063] The gas after spray purification will be discharged from the outlet pipe 410, and the dust particles inside the water after reuse will gradually tend to be saturated. At this time, it is necessary to open the valve on the first water pipe 5 to allow the water to flow into the filter box 51 for filtration, and part of the water can also flow into the evaporator 53 through the second water pipe 52 to be evaporated, so that the steam enters the inner cavity of the heating chamber 22, and cooperates with the airflow introduced by the air pipe 219 to sweep the activated carbon. The steam sweeping can wash away the dust and impurities in the activated carbon, thereby ensuring the adsorption performance of the activated carbon after regeneration, and further assisting the regeneration effect of the activated carbon;

[0064] The spraying liquid can also be replaced with the treatment liquid, and the full utilization of the treatment liquid can be ensured under the action of the water curtain assembly;

[0065] It should be noted that during the manufacturing process, a collection device may be provided on the surface of the heating chamber 22 to assist in collecting dust and impurities after sweeping and blowing. In addition, after the water in the evaporator 53 is evaporated into steam, impurities will remain inside the evaporator 53 and need to be cleaned in time to avoid affecting the evaporation performance of the evaporator 53.

[0066] A method for purifying waste gas, using a waste gas purification device as described above, comprises the following steps:

[0067] S1: First, the exhaust gas is introduced into the carbon box 11 for adsorption of activated carbon to achieve preliminary purification, and the first servo motor 2 is started to allow the activated carbon to enter the heating chamber 22 for thermal regeneration, and the regenerated activated carbon is re-introduced into the carbon box 11;

[0068] S2: The waste gas after being adsorbed by the activated carbon will enter the air suction chamber 3 and be sprayed and purified. The water after spraying will flow between the baffle 45 and the extrusion plate 43 and be driven into the inside of the spray pipe 47, so as to spray and purify the waste gas again;

[0069] S3: The sprayed water is passed into the filter box 51 through the first water pipe 5 for filtration, or it can be passed into the evaporator 53 for evaporation, so that the steam enters the heating chamber 22 to assist the regeneration of the activated carbon.
