[0019] S3, at this time, the driving motor causes its output end to respectively drive the fan blades and the half gear to rotate. When the fan blades rotate, the exhaust gas and some foam will enter the exhaust plug, and then the exhaust gas will be discharged from the exhaust pipe; when the half gear rotates, it will drive the gear ring 1, the connecting plate and the mounting plate to move back and forth, and the mounting plate will drive the tooth plate and the cleaning roller to move.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The industrial waste gas denitrification and desulfurization equipment provided by the present invention can increase the contact area and contact time with the waste gas, allowing the desulfurization reaction to be carried out more fully and efficiently, significantly improving the desulfurization effect, and capturing the foam flowing with the waste gas and effectively recovering it.

[0024] (2) The present invention fully utilizes the guiding role of the PVC pipe in gas transportation through the coordinated cooperation of the shell, blower, PVC pipe and bubble generator nozzle, which enables the bubble generator nozzle to stably and continuously form uniform bubbles; and cleverly utilizes the light and easy-floating characteristics of bubbles to allow them to smoothly pass through the filter disk and stay on the top of the filter disk to form a foam covering layer, thereby increasing the contact area and contact time between the limestone slurry and the exhaust gas. Specifically, the blower is driven to make the PVC pipe inject gas into the interior of the bubble generator nozzle, and the gas will be ejected from the interior of the bubble generator nozzle to generate bubbles in the limestone slurry. In the process of the bubbles not gathering, a large amount of fine and stable foam will be generated.

[0025] (3) The present invention uses the coordinated cooperation of the bubble treatment mechanism, the driving component and the reflux component to enable the cleaning roller to accurately and efficiently complete the defoaming treatment operation and quickly eliminate the excess foam in the exhaust plug; and cleverly uses the diversion effect of the reflux pipe to return the limestone slurry formed in the defoaming process to the interior of the connecting shell, thereby avoiding the waste of resources. Specifically, the driving motor drives the fan blades and the half gear to rotate at its output end respectively, and the gear ring drives the gear plate to make the cleaning roller roll inside the exhaust plug to defoam the foam entering the exhaust plug. The limestone slurry generated by eliminating the foam inside the exhaust plug will be guided into the interior of the reflux pipe by the guide plate and the guide block, and the limestone slurry inside the reflux pipe will flow back to the interior of the connecting shell, thereby realizing the recycling of foam, avoiding the waste of resources and reducing the operating cost.

[0026] (4) The present invention, through the coordinated cooperation of the gear ring 2, the L-shaped rod, the rack 2 and other components, not only realizes the use of the moving gear ring 1 to cleverly drive the extrusion wheel, and then accurately extrude the rack 2 to produce directional movement, providing a power basis for the operation of subsequent components; it also successfully drives the gear ring 2 and the bubble generator nozzle to rotate flexibly, creating favorable conditions for the rapid generation of foam and accelerating the generation of foam. Specifically, when the gear ring 1 moves, it will link the extrusion wheel to move back and forth, and when it moves, it will squeeze and push the connecting block to move, and the connecting block will drive the L-shaped rod and the rack 2 to move, and the rack 2 will drive the gear ring 2 and the bubble generator nozzle to rotate back and forth. By utilizing the rotation of the bubble generator nozzle, the generation of foam can be increased, and the efficiency of desulfurization can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Embodiment 1: see attached Figures 1 to 12 The industrial waste gas denitration and desulfurization equipment provided by the embodiment 1 comprises a tower body 100, further comprises a bubble generating mechanism 500, which is arranged at the top end of the inside of the tower body 100, the bubble generating mechanism 500 comprises a mounting block 501 fixedly connected to the top end of the inside of the tower body 100, a filter disc 502 is fixedly installed in the inside of the mounting block 501, a connecting shell 503 is fixedly installed at the bottom end of the filter disc 502, a blower 504 is fixedly installed on the outer surface of the tower body 100, a PVC pipe 505 is fixedly installed at the output end of the blower 504, one end of the PVC pipe 505 extends to the inside of the connecting shell 503, and a bubble generator nozzle 506 located at the bottom end of the filter disc 502 is rotatably connected, a dust removal assembly 200 is arranged on the outer surface of the tower body 100 and can filter the waste gas, a denitration assembly 300 is arranged at the bottom end of the inside of the tower body 100, and a desulfurization assembly 400 is arranged at the middle end of the inside of the tower body 100.

[0044] It is not difficult to understand that: through the operation personnel injects the limestone slurry and the foaming agent into the inside of the connecting shell 503 through the pipeline in the Figure 2 , and then injects the waste gas into the inside of the dust removal assembly 200, and the dust removal assembly 200 can filter the waste gas, and the filtered waste gas will enter the bottom end of the inside of the tower body 100, and the waste gas entering the bottom end of the inside of the tower body 100 will contact with the ammonia gas in the inside, so as to carry out the denitration treatment on the waste gas, and the waste gas after the denitration treatment will enter the middle end of the inside of the tower body 100, at this time, the desulfurization assembly 400 can be driven to spray the limestone slurry, and the slurry will be combined with the waste gas, so as to carry out the desulfurization treatment on the waste gas;

[0045] At the same time, the blower 504 can be driven to make the PVC pipe 505 inject gas into the inside of the bubble generator nozzle 506, and the gas will be sprayed from the inside of the bubble generator nozzle 506, with the injection of the gas, the bubbles will gradually be generated in the limestone slurry, in the process that the bubbles will not gather, a large amount of fine and stable bubbles will be generated, these bubbles will slowly pass through the filter disc 502 and finally stay at the top end of the filter disc 502 to form a bubble cover layer, when the waste gas rises and contacts with the bubble cover layer, the porous structure and the large surface area of the bubble greatly increase the contact area and the contact time with the waste gas, so that the desulfurization reaction can be carried out more fully and more efficiently, and the desulfurization effect is significantly improved.

[0046] As Figure 2As shown, the dust removal assembly 200 includes a fixed shell 202 fixedly connected to one side of the outer surface of the tower body 100, a draft fan 201 is provided on one side of the fixed shell 202, an air injection pipe located inside the draft fan 201 is provided at the output end of the fixed shell 202, and a filter cartridge 203 is inserted at the bottom end of the outer surface of the air injection pipe.

[0047] It is not difficult to understand that: through the design of the dust removal component 200, the exhaust gas can be injected into the induced draft fan 201, and then the fixed shell 202 can be driven to allow the air injection pipe to extract the exhaust gas inside the induced draft fan 201. In the process of extracting the exhaust gas, the filter cartridge 203 can filter the particles of the exhaust gas, and the filtered exhaust gas will enter the bottom end of the tower body 100.

[0048] like Figure 1 and Figure 2 As shown, the denitrification component 300 includes a heating wire 302 fixedly connected to the bottom end of the tower body 100, a liquid storage tank 301 is fixedly installed on the outer surface of the tower body 100, a nozzle 303 is fixedly installed inside the tower body 100, and an extraction pump 304 is provided at the top of the liquid storage tank 301, and the extraction pump 304 is connected to the nozzle 303 through a hose.

[0049] It should be noted that: through the design of the denitrification component 300, the heating wire 302 can be driven to heat the bottom end of the tower body 100 so that it is heated to a specified temperature, and then the extraction pump 304 can be driven to extract the ammonia water inside the liquid storage tank 301, and then the ammonia water will be sprayed out from the inside of the nozzle 303. The sprayed ammonia water will enter the high-temperature area and vaporize to form ammonia gas, and then enter the exhaust gas at the bottom end of the tower body 100, which will combine with the ammonia gas to denitrify the exhaust gas.

[0050] like Figure 1 and Figure 2 As shown, the desulfurization component 400 includes a liquid storage tank 2 401 fixedly connected to the outer surface of the tower body 100, an extraction pump 2 404 is provided at the top of the liquid storage tank 2 401, a nozzle 2 402 is fixedly installed at the middle end of the tower body 100, and the extraction pump 2 404 is connected to the nozzle 2 402 through a hose, and a connecting pipe 403 is fixedly installed on the outer surface of the tower body 100.

[0051] It should be noted that: through the design of the desulfurization component 400, after the denitrification of the exhaust gas is completed, the exhaust gas will pass through the connecting pipe 403 and enter the middle end of the tower body 100, and then the extraction pump 2 404 can be driven to make the hose extract the limestone slurry inside the liquid storage tank 2 401, and the limestone slurry will be sprayed out from the inside of the nozzle 2 402, and the sprayed limestone slurry will combine with the exhaust gas, thereby performing preliminary desulfurization treatment on the exhaust gas.

[0052] like Figure 3 、 Figure 11 and Figure 12 As shown, it also includes: a bubble processing mechanism 600, which is arranged inside the mounting block 501, and the bubble processing mechanism 600 includes an exhaust plug 601 fixedly connected to the interior of the mounting block 501, a slider 602 is slidably connected to the interior of the bottom end of the exhaust plug 601, a mounting plate 603 is fixedly mounted on the bottom end of the slider 602, and a tooth plate 604 is rotatably connected to the top end of the mounting plate 603. A cleaning roller 605 located inside the exhaust plug 601 is fixedly mounted on the top end of the tooth plate 604, and a rack 606 that meshes with the tooth plate 604 is fixedly mounted on the bottom end of the exhaust plug 601;

[0053] The driving assembly 700 is disposed on the outer surface of the mounting block 501 and is capable of driving the mounting plate 603 to move while extracting the exhaust gas.

[0054] It should be noted that: through the design of the bubble treatment mechanism 600, the driving component 700 can be driven to extract the exhaust gas that is fully combined with the foam, and the exhaust gas and part of the foam will enter the exhaust plug 601. At the same time, the driving component 700 can drive the mounting plate 603 to slide back and forth inside the bottom end of the exhaust plug 601, and the mounting plate 603 will drive the tooth plate 604 and the cleaning roller 605 to move. Because the tooth plate 604 is engaged with the rack 1 606, and then in the process of sliding, the tooth plate 604 will rotate along the surface of the rack 1 606, and the tooth plate 604 will drive the cleaning roller 605 to roll inside the exhaust plug 601. During the rolling process, the foam entering the exhaust plug 601 can be defoamed to prevent the foam and exhaust gas from being discharged together.

[0055] like Figure 4 、 Figure 7 and Figure 8 As shown, the drive assembly 700 includes an exhaust pipe 701 fixedly connected to the outer surface of the mounting block 501, a motor 702 is fixedly installed inside the exhaust pipe 701, and fan blades 703 and half gears 704 are fixedly installed at the output ends of the motor 702. A gear ring 706 is slidably mounted on the outer surface of the half gear 704, and the gear ring 706 is connected to the mounting plate 603 via a connecting plate 705.

[0056] It should be noted that: through the design of the drive component 700, the motor 702 can be driven so that its output end can respectively drive the fan blades 703 and the half gear 704 to rotate. When the fan blades 703 rotate, the exhaust gas that is fully combined with the foam can be extracted. Since the half gear 704 is engaged with the gear ring 1 706, when the half gear 704 rotates, it will drive the gear ring 1 706 to move back and forth, and the gear ring 1 706 will drive the connecting plate 705 and the mounting plate 603 to move back and forth.

[0057] like Figure 10 、 Figure 11 and Figure 12As shown, it also includes: a rotating mechanism 800, which is arranged on the surface of the bottom end of the bubble generator nozzle 506, the rotating mechanism 800 includes a gear ring 2 801 fixedly connected to the bottom end surface of the bubble generator nozzle 506, an L-shaped rod 802 is slidably connected to the inside of the connecting shell 503, one end of the L-shaped rod 802 is fixedly installed with a rack 2 803 engaged with the gear ring 2 801, and the other end of the L-shaped rod 802 is fixedly installed with a connecting block 805, an extrusion wheel 806 is provided on one side of the connecting block 805, and the extrusion wheel 806 is fixedly connected to the gear ring 1 706, and the rack 2 803 is elastically connected to the connecting shell 503 through an elastic member 804.

[0058] It is not difficult to understand that: through the design of the rotating mechanism 800, when the gear ring 1 706 moves, the extrusion wheel 806 will be linked to move back and forth, and when it moves, it will contact one side of the connecting block 805, and will squeeze and push the connecting block 805 to move, and the connecting block 805 will drive the L-shaped rod 802 and the rack 2 803 to move. When the rack 2 803 moves, the elastic member 804 will be stretched, and the resilience of the elastic member 804 will be used to make the L-shaped rod 802 and the rack 2 803 move back and forth, and the rack 2 803 will mesh with the gear ring 2 801, thereby moving the rack 2 80 3 will drive the gear ring 2 801 and the bubble generator nozzle 506 to rotate back and forth. The rotation of the bubble generator nozzle 506 can increase the generation of foam and improve the efficiency of desulfurization. Blocking blocks are provided on both sides of the surface of the L-shaped rod 802. When the L-shaped rod 802 moves inside the mounting block 501, it can block the connecting shell 503 to prevent the exhaust gas from directly passing through the mounting block 501 and being discharged outside the equipment. The connecting shell 503 is divided into two layers. The top layer is provided with limestone slurry and foaming agent, and the bottom layer is provided with the gear ring 2 801, the L-shaped rod 802 and the rack 2 803.

[0060] It is not difficult to understand that: through the design of the reflux component 900, the limestone slurry generated by the cleaning roller 605 to eliminate the foam inside the exhaust plug 601 will fall on the surface of the guide plate 901, and the desulfurization-completed exhaust gas will be discharged from the exhaust pipe 701, and the defoaming-completed limestone slurry will be guided by the guide plate 901 to the surface of the guide block 902, and the guide block 902 will guide the limestone slurry into the reflux pipe 903, and the limestone slurry inside the reflux pipe 903 will flow back to the inside of the connecting shell 503.

[0061] like Figure 7 and Figure 8 As shown, the top ends of the tooth plate 604 and the mounting plate 603 are both conical in design, and a limiting ring located inside the mounting plate 603 is provided at the bottom end of the tooth plate 604 .

[0062] It is not difficult to understand that: through the design of the mounting plate 603 and the tooth plate 604, since the top ends of the mounting plate 603 and the tooth plate 604 are both conical in design, the limestone slurry formed by eliminating bubbles on the cleaning roller 605 remains on the top ends of the mounting plate 603 and the tooth plate 604, and a limiting ring is provided at the bottom end of the tooth plate 604, which can support and limit the tooth plate 604 and the cleaning roller 605.

[0063] The present invention also provides a method for using an industrial waste gas denitration and desulfurization device, which comprises the following steps:

[0064] S1, limestone slurry and foaming agent are injected into the connecting shell 503, exhaust gas is injected into the induced draft fan 201, and the fixed shell 202 is driven to cause the gas injection pipe to extract the exhaust gas from the induced draft fan 201. During the exhaust gas extraction process, the filter cartridge 203 can filter the exhaust gas particles. Then, the heating wire 302 is driven to heat the bottom end of the tower body 100 to a specified temperature. The extraction pump 1 304 is driven to cause the nozzle 1 303 to spray ammonia water. The sprayed ammonia water enters the high-temperature area, where it vaporizes to form ammonia gas. The exhaust gas entering the bottom end of the tower body 100 combines with the ammonia gas, thereby denitrifying the exhaust gas.

[0065] S2, the exhaust gas after denitrification will pass through the connecting pipe 403 and enter the middle end of the tower body 100, driving the second extraction pump 404 to spray limestone slurry from the inside of the second nozzle 402, and the sprayed limestone slurry will combine with the exhaust gas, thereby performing preliminary desulfurization treatment on the exhaust gas. At the same time, the blower 504 is driven to make the PVC pipe 505 inject air into the inside of the bubble generator nozzle 506 to generate bubbles. In the process of the bubbles not gathering, foam will be generated. The bubbles will slowly pass through the filter disk 502 and finally stay on the top of the filter disk 502, forming a foam covering layer, thereby increasing the contact area and contact time with the exhaust gas;

[0066] S3, at this time, the driving motor 702 causes its output end to respectively drive the fan blade 703 and the half gear 704 to rotate. When the fan blade 703 rotates, the exhaust gas and part of the foam will enter the exhaust plug 601, and then the exhaust gas will be discharged from the exhaust pipe 701; when the half gear 704 rotates, it will drive the gear ring 1 706, the connecting plate 705 and the mounting plate 603 to move back and forth, and the mounting plate 603 will drive the tooth plate 604 and the cleaning roller 605 to move. The tooth plate 604 will rotate along the surface of the rack 1 606, and the tooth plate 604 will drive the cleaning roller 605 to roll inside the exhaust plug 601. During the rolling process, the foam entering the exhaust plug 601 can be defoamed;

[0067] S4, when the gear ring 1 706 moves, it will link the extrusion wheel 806 to move back and forth, and when it moves, it will squeeze and push the connecting block 805 to move, and the connecting block 805 will drive the L-shaped rod 802 and the rack 2 803 to move, and the rack 2 803 will drive the gear ring 2 801 and the bubble generator nozzle 506 to rotate back and forth. The rotation of the bubble generator nozzle 506 can increase the generation of foam and improve the efficiency of desulfurization;

[0068] S5, the limestone slurry produced by eliminating the foam inside the exhaust plug 601 will fall on the surface of the guide plate 901, and the desulfurized exhaust gas will pass through the holes on the surface of the guide plate 901 and be discharged from the exhaust pipe 701, and the limestone slurry after defoaming will be guided by the guide plate 901 to the surface of the guide block 902, and the guide block 902 will guide the limestone slurry into the return pipe 903, and the limestone slurry inside the return pipe 903 will flow back to the inside of the connecting shell 503.
