[0033] Example:

[0034] Reference Figure 1-Figure 8 , an industrial waste gas adsorption and purification treatment device, including a treatment box 1, a plurality of observation ports 27 are arranged on the outside of the treatment box 1 to facilitate observation of the treatment status of the waste gas inside the treatment box 1, and also includes: an air inlet 2 and an exhaust port 3 opened on the treatment box 1, and a burner can also be arranged at the exhaust port 3 to burn the waste gas after adsorption and purification to improve the purification effect of the waste gas, and an exhaust gas circulation adsorption unit is arranged between the air inlet 2 and the exhaust port 3, which is used to transport the industrial waste gas into the treatment box 1 and discharge the treated waste gas to the outside of the treatment box 1; a filtering and collecting unit arranged on the inner wall of the treatment box 1, which is used to filter and collect dust in the waste gas; a dehumidification unit arranged on the inner wall of the treatment box 1, which is used to liquefy and collect water vapor in the high-temperature waste gas, wherein the dehumidification unit and the filtering and collecting unit are connected by a pipeline; a drying unit arranged on the treatment box 1, and the waste gas circulation unit can drive the drying unit to rotate, which is used to dry the dehumidified waste gas.

[0035] Reference Figure 1-Figure 3 The exhaust gas circulation unit includes a driving motor 4 fixedly connected to the outer wall of the treatment box 1, and a rotating shaft 5 is rotatably connected inside the treatment box 1. A first bevel gear set 6 is arranged between the bottom end of the rotating shaft 5 and the output end of the driving motor 4, and an exhaust fan 16 is fixedly connected to the top of the rotating shaft 5. An adsorbent 15 is fixedly connected to the side of the treatment box 1 close to the exhaust fan 16, wherein the exhaust port 3 is located at the top of the treatment box 1, and the exhaust fan 16 is located inside the exhaust port 3, and the adsorbent 15 is rotatably connected to the rotating shaft 5.

[0036] It needs to be explained that the meshing method between the first bevel gear set 6 can refer to the technical solution in the prior art, which can be known to technicians in this field and will not be elaborated on. When the exhaust fan 16 rotates, the exhaust gas in the treatment box 1 can be discharged, so that the interior of the treatment box 1 is in a negative pressure state, so that the exhaust gas enters the interior of the treatment box 1 from the air inlet 2 to achieve continuous treatment of the exhaust gas.

[0037] Reference Figure 3 and Figure 6The filtering and collecting unit comprises a collecting plate 7 fixedly connected to the inner wall of the processing box 1, and a collecting box 8 is detachably connected to the side of the outer wall of the processing box 1 near the collecting plate 7. The collecting plate 7 is arranged in a ring-shaped inclined manner and is hollow. The collecting box 8 is connected to the processing box 1, and the bottom of the collecting plate 7 is connected to the bottom of the collecting box 8, wherein an anti-stacking mechanism is arranged on the side of the rotating shaft 5 near the bottom of the collecting plate 7, and a dust removal mechanism 9 is arranged inside the processing box 1, and the dust removal mechanism 9 is located above the collecting plate 7. The anti-stacking mechanism comprises a knocking rod 71 rotatably connected to the rotating shaft 5, and the end of the knocking rod 71 is close to the collecting plate 7, and the side of the rotating shaft 5 near the knocking rod 71 is rotatably connected to a sealing cylinder 72, and the inside of the sealing cylinder 72 is slidably connected to a movable rod 73 rotatably connected to the knocking rod 71, and a first spring 74 is fixedly connected between the movable rod 73 and the sealing cylinder 72.

[0038] The dust that falls off the filter plate 92 will fall onto the collecting plate 7. At the same time, by intermittently delivering gas into the sealing tube 72, the movable rod 73 can drive the knocking rod 71 to intermittently contact the collecting plate 7, thereby knocking the collecting plate 7. During the knocking process, the dust will continue to slide downward until it is collected in the collecting box 8, so as to centrally process the dust in the exhaust gas and improve the adsorption capacity of the subsequent adsorption component 15.

[0039] Reference Figure 3 , Figure 4 and Figure 7 The dust removal mechanism 9 includes a fixing member 91 fixedly connected to the rotating shaft 5, a mounting groove is provided on the top of the fixing member 91, a filter plate 92 is slidably connected inside the mounting groove, a plurality of sets of vibrating cylinders 93 and second springs 94 are fixedly connected between the filter plate 92 and the bottom of the mounting groove, an annular groove 95 is provided on the outer wall of the fixing member 91, a scraper bar 96 is slidably connected inside the annular groove 95, wherein the fixing member 91 is in the shape of a truncated cone, and the size of the bottom of the fixing member 91 is larger than the size of the hollow of the collecting plate 7, the filter plate 92 is in a circular inclined shape and the end is tightly fitted with the inner wall of the processing box 1, and the scraper bar 96 is fitted with the bottom of the filter plate 92.

[0040] It should be explained that the surface of the filter plate 92 is usually uniformly provided with a plurality of groups of tiny holes, which can intercept the dust in the exhaust gas while ensuring the passage of gas. When the exhaust gas is transported, the rotating shaft 5 will drive the fixing member 91 and the filter plate 92 to rotate, so that the dust on the surface of the filter plate 92 is thrown to the collecting box 8 under the action of centrifugal force, so as to speed up the dust collection efficiency, reduce the adhesion between the dust and the filter plate 92, and improve the filtering effect and efficiency of the filter plate 92. In addition, the filter plate 92 can prevent tiny dust from passing through the filter plate 92 by rotating, thereby improving the efficiency of the filter. The cleaning effect of dust in high exhaust gas; at the same time, the dust falling on the fixing part 91 will gradually fall onto the collecting plate 7. During the rotation, due to the sliding connection between the scraper strip 96 and the annular groove 95, when the fixing part 91 rotates, the scraper strip 96 and the annular groove 95 can be made to rotate relative to each other, so that the scraper strip 96 cleans the dust on the surface of the filter plate 92 to prevent the dust from causing clogging of the filter plate 92. In addition, during the rotation, the filter plate 92 can also be driven to vibrate by the vibrating cylinder 93 to further improve the cleaning effect of the dust on the surface of the filter plate 92.

[0041] Reference Figure 3 , Figure 5 and Figure 8 The dehumidification unit includes a flow guide 10, a liquid storage plate 12 and a mist blocking plate 13 fixedly connected to the inner wall of the treatment box 1, a first heat exchange ring 11 is fixedly connected to the outer wall of the flow guide 10, the side of the liquid storage plate 12 away from the inner wall of the treatment box 1 is inclined upward, the mist blocking plate 13 is inclined, and a water inlet pipe 17 connected to the first heat exchange ring 11 is fixedly connected to the outer wall of the treatment box 1, wherein the flow guide 10 is located above the filter plate 92, the liquid storage plate 12 is located above the flow guide 10, the mist blocking plate 13 is located above the liquid storage plate 12, a drain port 14 is provided on the side of the outer wall of the treatment box 1 close to the liquid storage plate 12, and a flow increase mechanism is provided at the bottom of the mist blocking plate 13. The flow mechanism includes a tilted ring 131 fixedly connected to the bottom of the mist blocking plate 13, and a plurality of grooves 132 are provided on the inner wall of the tilted ring 131. A vibration protrusion 133 is slidably connected inside the groove 132. A support cylinder 135 and a third spring 136 are fixedly connected between the vibration protrusion 133 and the groove 132. A pressing block 134 is fixedly connected to the side of the rotating shaft 5 close to the vibration protrusion 133, wherein the tilted ring 131 is perpendicular to the mist blocking plate 13, the rotating shaft 5 passes through the tilted ring 131, and a pressing block 134 is fixedly connected to the side of the rotating shaft 5 close to the vibration protrusion 133, and the support cylinder 135 is connected to the sealing tube 72 and the vibration cylinder 93 through a pipeline.

[0042] The specific structure of the mist blocking plate 13 can refer to the technical solutions in the prior art. Those skilled in the art will know that it will not be elaborated here. The exhaust gas after dust removal will be concentrated through the guide member 10 and flow to the mist blocking plate 13. When flowing through the guide member 10, the water inlet pipe 17 will convey the cooling water to the first heat exchange ring 11 to cool the high-temperature exhaust gas. During the cooling process, the water vapor in the exhaust gas will be liquefied into mist. When flowing through the mist blocking plate 13, the water mist can be intercepted and collected. When the cooling water flows to the connecting pipe 18, it will be heated. As the water mist on the mist blocking plate 13 increases, it will gradually condense into water droplets, and then flow to the bottom along the mist blocking plate 13, and finally drip into the liquid storage plate 12. The collected liquid can be discharged through the drain port 14. The exhaust gas is collected, and in this process, the water-soluble substances in the exhaust gas will dissolve in the water droplets, and with the rotation of the rotating shaft 5, the pressing block 134 will be driven to intermittently contact the vibrating protrusion 133, and the pressing block 134 will first drive the vibrating protrusion 133 to move into the groove 132, and at the same time compress the supporting cylinder 135 to deliver the compressed gas to the vibrating cylinder 93 and the sealing tube 72, and when the pressing block 134 is separated from the vibrating protrusion 133, the vibrating protrusion 133 will move to the initial position under the action of the third spring 136, thereby driving the vibrating protrusion 133 to vibrate, and since the inclined ring 131 is vertically arranged with the mist blocking plate 13, during vibration, the movement of water droplets on the mist blocking plate 13 will be accelerated, thereby improving the collection efficiency of water droplets.

[0043] Reference Figure 3 The drying unit includes an air inlet pipe 20 fixedly connected to the outer wall of the processing box 1, the air inlet pipe 20 is located between the mist blocking plate 13 and the adsorbent 15, the air inlet pipe 20 is rotatably connected to the inside of the horizontal shaft 22, a second bevel gear set 26 is provided between the horizontal shaft 22 and the rotating shaft 5, an end of the horizontal shaft 22 away from the second bevel gear set 26 is fixedly connected to the air inlet fan 23, and also includes a heating ring 24 fixedly connected to the inside of the air inlet pipe 20, a second heat exchange ring 21 is fixedly connected to the outer wall of the air inlet pipe 20, and the second heat exchange ring A connecting pipe 18 is connected between 21 and the first heat exchange ring 11, and a return pipe 25 is connected to the second heat exchange ring 21 and penetrates to the outside of the processing box 1, wherein the second heat exchange ring 21 and the heating ring 24 are staggered, the connecting pipe 18 is located below the second heat exchange ring 21, and the return pipe 25 is located above the second heat exchange ring 21, and also includes a plurality of groups of nozzles 19 connected to the connecting pipe 18, and the outlet of the nozzle 19 is close to the mist blocking plate 13, when the nozzle 19 sprays water, it can be evenly sprayed on the mist blocking plate 13.

[0044] When the rotating shaft 5 rotates, the second bevel gear set 26 drives the air intake fan 23 to rotate, and the external dry air is delivered to the interior of the treatment box 1. It should be explained that the heating ring 24 and the second heat exchange ring 21 can be staggered, so that the air first passes through the second heat exchange ring 21 and then passes through the heating ring 24. This is a conventional method in the prior art, so it is not elaborated. The heated cooling water will be delivered to the second heat exchange ring 21 to preliminarily heat the air, and then pass through the heating ring 24 to heat the air, thereby drying the subsequent exhaust gas to improve the adsorption efficiency of the adsorption element 15, and oxygen can be delivered to the exhaust gas to facilitate the subsequent combustion treatment of the exhaust gas and improve the purification effect of the exhaust gas. In addition, when the cooling water is delivered, part of it will be sprayed onto the mist blocking plate 13 through the nozzle 19. On the one hand, the mist blocking plate 13 can be cleaned, and on the other hand, the treatment of water-soluble substances in the exhaust gas can be improved.
