Description

Technical Field

[0001] The present application relates to the field of waste gas purification, and more particularly, to a waste gas purification device for processing coarse woolen fabrics. Background Art

[0002] Waste gas treatment refers to the pre-treatment of waste gas generated in industrial sites such as factories and workshops before external discharge to meet the national standards for external discharge of waste gas. Waste gas is also generated during the processing of coarse woolen fabrics, so waste gas treatment is also required.

[0003] Most of the existing treatment methods are carried out through a purification tower. The waste gas is purified by spraying a washing liquid and then discharged. In actual purification and washing, due to certain limitations in the spraying area, spraying blind spots will be generated. At the same time, the residence time of the waste gas is short, resulting in poor washing effects. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a waste gas purification device for processing coarse woolen fabrics, which solves the problems raised in the above background art.

[0005] To achieve the above object, the present application provides a waste gas purification device for processing coarse woolen fabrics, including a purification tower main body and a secondary filtration pool. An exhaust gas delivery pipe is assembled on the side of the purification tower main body, and an exhaust pipe is assembled at the top of the purification tower main body, and the end of the exhaust pipe is located in the secondary filtration pool; A pipe one that can be externally connected to a water pump is assembled in the middle of the purification tower main body. Four pipe twos arranged in an annular array are externally connected to the side of the pipe one. A plurality of rotary joints are assembled at the bottom of each pipe two. An impeller is rotatably connected inside the pipe one, and a cross-shaped convex block is connected to the bottom of the impeller through a connecting rod; A cross-shaped support frame is fixed inside the purification tower main body. A plurality of spray heads are rotatably connected inside the cross-shaped support frame. Each spray head is connected to the rotary joint, and a gear one is fixed on the outside of each spray head. Four symmetrically distributed L-shaped sliding rods are fixed on the upper surface of the cross-shaped support frame. A toothed rod is slidably sleeved on the outside of each sliding rod, and a spring is fixed between the inside of each toothed rod and each sliding rod. By arranging a plurality of spray heads to spray the washing liquid in all directions, the impeller is rotated by the power generated by the flow of the washing liquid. Subsequently, under the action of the impeller, the cross-shaped convex block is rotated, so that it rotates and presses a plurality of toothed rods, causing the toothed rods to push the gear one to rotate, and then causing a plurality of spray heads to rotate simultaneously, so that the spraying areas overlap, thereby increasing the contact area between the washing liquid and the waste gas.

[0006] Preferably, a long rod is fixed to the bottom of the cross-shaped convex block, and a bevel gear one is fixed to the bottom of the long rod.

[0007] Preferably, one side of the tooth bar close to the cross-shaped projection is a spherical structure and is located within the movement track of the cross-shaped projection, and each tooth bar meshes with three of the first gears in sequence.

[0008] Preferably, a particle adsorption assembly is assembled at the lower end of the middle part of the main body of the purification tower, a filter disk is assembled at the lower end inside the main body of the purification tower, and a slag scraping assembly is assembled on the upper surface of the filter disk.

By arranging the particle adsorption assembly, when the cross-shaped projection rotates, the first bevel gear is driven to rotate by the long rod at its bottom, and then the second bevel gear meshing with it will drive the middle first rotating rod to rotate. Under the action of the two transmission belts, the other two first rotating rods rotate. At this time, the three first rotating rods rotate, and the annular sleeves assembled on them rotate accordingly, and the graphite adsorption plates connected by the connecting rods rotate accordingly. At the same time, a plurality of teeth on the annular plate will mesh with the second gears in sequence, driving the second gears to rotate. At this time, the graphite adsorption plates will rotate around the first rotating rods while also rotating around their own axes, better contacting the waste gas and improving the impurity adsorption efficiency.

[0010] Preferably, a plurality of teeth are arranged on the annular plate and mesh with the second gears, and the second bevel gear and the first bevel gear.

[0012] Preferably, a through cavity is formed in the middle of the shovel plate, and drainage micropores communicating with the through cavity are formed on the side surface of the shovel plate. By arranging the slag scraping assembly, while the particle adsorption assembly is working, the second bevel gear will drive the third bevel gear to rotate, and then drive the second rotating rod to rotate, so that the shovel plate assembled on its outside rotates to remove the impurities on the filter disk and ensure its filtering efficiency. At the same time, the shovel plate can collect the impurities in the through cavity inside the shovel plate while removing the impurities, which is convenient for collection and treatment.

[0013] The advantages of the present application are as follows: (1) By arranging multiple nozzles to spray the cleaning liquid in all directions, the power generated by the flow of the cleaning liquid makes the impeller rotate. Subsequently, under the action of the impeller, the cross-shaped convex block rotates, squeezing multiple rack bars, causing the rack bars to push the first gear to rotate, and then making multiple nozzles rotate simultaneously, overlapping the spraying areas, thereby increasing the contact area between the cleaning liquid and the waste gas.

[0014] (2) By arranging a particle adsorption assembly, when the cross-shaped convex block rotates, the long rod at its bottom drives the first bevel gear to rotate. Subsequently, the meshing second bevel gear drives the middle first rotating rod to rotate. Under the action of two transmission belts, the other two first rotating rods rotate. At this time, the three first rotating rods rotate, and the annular sleeves assembled thereon rotate accordingly. The graphite adsorption plates connected by connecting rods thereon rotate accordingly. At the same time, multiple teeth on the annular plate will sequentially engage with the second gear, driving the second gear to rotate. At this time, the graphite adsorption plates will rotate around the first rotating rod while also rotating on their own axes, better contacting the waste gas and improving the impurity adsorption efficiency.

[0015] (3) By arranging a slag scraping assembly, while the particle adsorption assembly is working, the second bevel gear drives the third bevel gear to rotate. Subsequently, it drives the second rotating rod to rotate, causing the scraper plate assembled on its outer part to rotate, removing the impurities on the filter disc to ensure its filtering efficiency.

[0024] Embodiment 1 See Figures 1 - 6, this embodiment provides an exhaust gas purification device for processing coarse woolen fabrics, including a purification tower main body 100 and a secondary filtration tank 200. An exhaust gas delivery pipe 300 is assembled on the side of the purification tower main body 100, and an exhaust pipe 400 is assembled at the top of the purification tower main body 100, and the end of the exhaust pipe 400 is located inside the secondary filtration tank 200; In the middle of the interior of the purification tower main body 100, a pipe one 610 that can be externally connected to a water pump is assembled. Four pipe twos 630 arranged in an annular array are externally connected to the side of the pipe one 610. A plurality of rotary joints are assembled at the bottom of each pipe two 630. An impeller 6110 is rotatably connected inside the pipe one 610. The bottom of the impeller 6110 is connected by a connecting rod to a cross-shaped convex block 6100; A cross-shaped support frame 620 is fixed inside the purification tower main body 100. A plurality of spray heads 640 are rotatably connected inside the cross-shaped support frame 620. Each spray head 640 is connected to the rotary joint, and a gear one 650 is fixed on the outside of each spray head 640. Four symmetrically distributed L-shaped sliding rods 660 are fixed on the upper surface of the cross-shaped support frame 620. A toothed rod 670 is slidably sleeved on the outside of each sliding rod 660. A spring is fixed between the inside of each toothed rod 670 and each sliding rod 660. A long rod 680 is fixed at the bottom of the cross-shaped convex block 6100. A bevel gear one 690 is fixed at the bottom of the long rod 680. One side of the toothed rod 670 close to the cross-shaped convex block 6100 is a spherical structure and is located within the movement track of the cross-shaped convex block 6100. Each toothed rod 670 is sequentially meshed with three of the gear ones 650. By arranging a plurality of spray heads 640 to spray the washing liquid in all directions, the impeller 6110 is rotated by the power generated by the flow of the washing liquid. Subsequently, under the action of the impeller 6110, the cross-shaped convex block 6100 is driven to rotate, so that it rotates and presses a plurality of toothed rods 670, causing the toothed rods 670 to push the gear ones 650 to rotate, and then causing a plurality of spray heads 640 to rotate simultaneously, so that the spraying areas overlap, thereby increasing the contact area between the washing liquid and the exhaust gas.

[0025] When the above-mentioned device is in specific use, firstly, the waste gas generated during the processing of the woolen fabric is transported into the lower end area inside the purification tower main body 100 through the waste gas delivery pipe 300. At this time, a water pump is externally connected to the end of the first pipe 610, and the water pump is externally connected to a washing liquid storage tank. The washing liquid in the washing liquid storage tank is sent into the first pipe 610 through the water pump. Subsequently, these pressurized washing liquids enter the four second pipes 630 respectively along the first pipe 610, and then are sprayed out through a plurality of nozzles 640 to contact the waste gas entering the purification tower main body 100, and the impurities in the waste gas are washed and separated. At the same time, after the pressurized washing liquid rushes into the first pipe 610, the impeller 6110 will be driven to rotate under the action of the impact force. The rotation of the impeller 6110 will drive the cross-shaped convex block 6100 to rotate. Subsequently, the cross-shaped convex block 6100 will intermittently squeeze the toothed rod 670, and under the resilience of the sliding rod 660 and the internal spring, it will move in a reciprocating cycle. During its movement, it will engage with the first gear 650 and drive the first gear 650 to rotate. At this time, the rotation of the first gear 650 will drive the nozzle 640 to rotate cyclically, so that the nozzle 640 rotates while spraying the washing liquid, and the spraying area overlaps, so as to increase the contact area between the washing liquid and the waste gas.

[0026] Example 2 See Figures 1 - 9, on the basis of Embodiment 1, a particle adsorption assembly 700 is assembled at the lower end of the middle part of the purification tower main body 100.

The middle first rotating rod 710 is respectively connected to the other two first rotating rods 710 through two transmission belts 740. A second bevel gear 730 is fixedly connected to the middle of the middle first rotating rod 710. The annular plate 7100 is provided with a plurality of teeth and meshes with the second gear 780. The second bevel gear 730 and the first bevel gear 690. By setting the particle adsorption assembly 700, when the cross-shaped convex block 6100 rotates, the first bevel gear 690 is driven to rotate by the long rod 680 at its bottom. Subsequently, the second bevel gear 730 meshing with it will drive the middle first rotating rod 710 to rotate. Under the action of the two transmission belts 740, the other two first rotating rods 710 rotate. At this time, the three first rotating rods 710 rotate, and the annular sleeves 750 assembled thereon rotate accordingly. The graphite adsorption plates 790 connected thereto through the connecting rods 770 rotate accordingly. At the same time, the plurality of teeth on the annular plate 7100 will sequentially mesh with the second gear 780, driving the second gear 780 to rotate. At this time, the graphite adsorption plate 790 will rotate around the first rotating rod 710 while also rotating on its own axis, better contacting the waste gas and improving the impurity adsorption efficiency.

[0027] When the above equipment is specifically used, when the waste gas enters the purification tower main body 100 through the waste gas delivery pipe 300, it will first come into contact with the particle adsorption assembly 700.

At the same time, the plurality of teeth on the annular plate 7100 will sequentially mesh with the second gear 780, driving the second gear 780 to rotate. At this time, the graphite adsorption plate 790 will rotate around the first rotating rod 710 while also rotating on its own axis, better contacting the waste gas and improving the impurity adsorption efficiency.

A through cavity 840 is formed in the middle of the shovel plate 830. Drainage micropores 850 communicating with the through cavity 840 are formed on the side surface of the shovel plate 830. By setting the slag scraping assembly 800, while the particle adsorption assembly 700 is working, the second bevel gear 730 will drive the third bevel gear 820 to rotate. Subsequently, the second rotating rod 810 is driven to rotate, so that the shovel plate 830 assembled outside it rotates to remove impurities on the filter plate 500, ensuring its filtration efficiency. At the same time, while the shovel plate 830 is capable of removing impurities, it can collect the impurities in the through cavity 840 inside the shovel plate 830, which is convenient for collection and treatment.
