Description

Technical Field

[0001] The present invention relates to the technical field of spray systems, and more specifically, to a spray system for industrial waste gas treatment. Background Art

[0002] A spray system for industrial waste gas treatment is a common waste gas treatment device, mainly used to remove particulate matter, organic compounds, gaseous pollutants, etc. in industrial waste gas. Its working principle is to atomize a liquid (such as water or chemical solution) into tiny droplets through a spray head, and then let these droplets fully contact the waste gas. Pollutants in the waste gas are dissolved, absorbed or reacted because of contacting with the droplets. These absorbed or reacted pollutants fall together with the droplets and are finally concentrated in the liquid, so as to achieve the purpose of purifying the waste gas. It is widely used in multiple industrial fields, including electronics, chemical industry, machinery, food, leather, papermaking, building materials, pharmaceutical, printing and dyeing, metal smelting and cement production, etc.

[0003] In the existing spray system, the liquid atomized into tiny droplets is sprayed into the interior of the tank body through a spraying hole, so that the droplets fully contact the waste gas, and the pollutants in the waste gas contact the droplets, so as to dissolve, absorb or react the pollutants, and finally fall together with the droplets and are concentrated in the liquid. However, because there are some impurities in the liquid, after long-term use of the spraying hole, the impurities will accumulate and cause the blockage of the spraying hole, affecting the normal use of the spray system. The common treatment method is to stop the spray system and then clean the spraying hole, which greatly reduces the working efficiency of the spray system. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) In this solution, by setting the through-hole assembly, when the liquid enters the spray head and is sprayed out through the spray holes, the impeller is driven to rotate, thereby driving the brush to insert into the spray holes, and at the same time causing the brush to reciprocate up and down in the spray holes, so as to clean the inside of the spray holes, and then dredge the blocked spray holes. At the same time, it is not necessary to stop the operation of the spray system, which improves the working efficiency of the spray system.

[0019] (2) In this solution, by setting the discharge assembly, when the brush moves upward and inserts into the spray holes, the trapezoidal slider is driven to move upward at the same time, and then the slide bar is driven to move by the first spring, so that the through hole coincides with the discharge port, and the liquid in the spray head can be sprayed out from the discharge port, thereby increasing the spraying amount of the liquid sprayed out of the spray head, and further improving the working efficiency and use effect of the spray system.

[0020] (3) In this solution, by setting the monitoring assembly, when the spray holes are blocked and the liquid in the spray head cannot flow downward, the floating block is driven to move upward by its own buoyancy, thereby driving the first slider to move upward to start the discharge assembly, so that the liquid in the spray head flows downward and is sprayed out from the discharge port, and then the through-hole assembly is started, which improves the practicability of the through-hole assembly.

[0021] (4) In this solution, by setting the rotating assembly, the main water pipe is driven by starting the motor, and at the same time, the mounting slider is driven to rotate around the sleeve through the spray head. Then, through the meshing of the third gear and the ring gear, when the third gear rotates around the sleeve, it can rotate itself at the same time. Then, the brush is driven to rotate by the mounting slider, so that when the brush reciprocates up and down in the spray holes, the brush can rotate itself, so that the bristles of the brush are in more comprehensive contact with the inside of the spray holes, and the brush can clean the inside of the spray holes more comprehensively, improving the use effect of the through-hole assembly.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Please refer to Figures 1 to 12 , a spray system for industrial waste gas treatment, including a treatment tank body 1. A main water pipe 2 is provided in the middle of the lower surface of the treatment tank body 1. The upper end of the main water pipe 2 penetrates into the interior of the treatment tank body 1 and is fixedly connected with a four-way joint 3. Four ends of the four-way joint 3 are commonly fixedly connected with an annular spray pipe 4. The lower end of the outer circumferential surface of the annular spray pipe 4 is fixedly connected with evenly distributed spray heads 10, and spraying holes 11 are formed on the lower surfaces of the spray heads 10. One side of the lower surface of the treatment tank body 1 is fixedly connected with a drain pipe 12;

[0044] A through-hole assembly 5 is arranged on the lower surface of the spray head 10. The through-hole assembly 5 includes a second annular chute 58 arranged on the outer side of the lower surface of the spray head 10. An installation slider 510 is slidably connected inside the second annular chute 58. The lower side of the inner circumferential surface of the installation slider 510 is fixedly connected with a cross-shaped fixing frame 511. The central position of the upper surface of the cross-shaped fixing frame 511 is fixedly connected with a brush 512, and the brush 512 is located directly below the spray head 10. The upper end of the brush 512 is fixedly connected with a conical block 513.

[0045] As Figure 3 ,Figure 4 , Figure 5 As shown, there are eight spray heads 10 provided. At the upper ends of the inner walls of the eight second annular chutes 58, first annular chutes 56 are respectively opened. Inside the first annular chutes 56, sliding rings 57 are slidably connected. And a connecting ring 59 is arranged between the sliding ring 57 and the mounting slider 510. On one side of the inner walls of the eight spray heads 10 close to the upper ends of the first annular chutes 56, rotating grooves 51 are respectively opened. Inside the rotating grooves 51, annular bevel gears 52 are rotatably connected. On the inner circular surfaces of the annular bevel gears 52, impellers 53 are fixedly connected. And the impellers 53 are located inside the spray heads 10. On both sides inside the rotating grooves 51, bevel gears 54 are rotatably connected. And the two bevel gears 54 are meshed with the annular bevel gears 52. On the lower surfaces of the two bevel gears 54, reciprocating lead screws 55 are fixedly connected. The lower ends of the two reciprocating lead screws 55 both extend into the sliding ring 57, and the two reciprocating lead screws 55 are both threadedly connected with the sliding ring 57.

[0046] As Figure 1 , Figure 2 As shown, on one side of the lower side of the outer surface of the treatment tank body 1, an air inlet pipe 13 is fixedly connected. And one end of the air inlet pipe 13 extends into the treatment tank body 1. On the upper surface of the treatment tank body 1, an exhaust pipe 14 is fixedly connected.

[0047] As Figure 1 , Figure 2 As shown, at a position on the inner wall of the treatment tank body 1 above the air inlet pipe 13, a filter screen 15 is fixedly connected. And the main water pipe 2 penetrates through the filter screen 15. At a position on the inner wall of the treatment tank body 1 above the annular spray pipe 4, a gas-liquid separator 16 is fixedly connected.

[0048] During use, the waste gas is discharged into the treatment tank body 1 through the air inlet pipe 13. First, large-particle pollutants in the waste gas are filtered out by the filter screen 15. Then, an external water supply device adds liquid to the main water pipe 2, and then it enters the annular spray pipe 4 through the four-way joint 3, then enters the spray heads 10, and finally is sprayed out through the spray holes 11, so that the liquid fully contacts the waste gas, dissolves, absorbs or reacts with the pollutants in the waste gas, and then falls together with the liquid droplets. Finally, it is discharged through the drain pipe 12. Then, the liquid contained in the treated waste gas is separated by the gas-liquid separator 16, and then the treated waste gas is discharged through the exhaust pipe 14.

[0049] However, after the spraying holes 11 have been used for a long time, impurities inside the liquid will accumulate and cause blockage of the spraying holes 11, affecting the normal use of the spraying system. It is necessary to shut down the spraying system and then clean the spraying holes 11, which greatly reduces the working efficiency of the spraying system. Therefore, a through-hole assembly 5 is provided. When the liquid enters the spray head 10 and is sprayed out through the spraying holes 11, it will drive the impeller 53 to rotate, and at the same time drive the annular bevel gear 52 to rotate in the rotating groove 51, thereby driving the two bevel gears 54 to rotate simultaneously, and at the same time driving the two reciprocating lead screws 55 to rotate, thereby driving the sliding ring 57 to reciprocate up and down in the first annular chute 56, and then driving the mounting slider 510 to reciprocate up and down in the second annular chute 58 through the connecting ring 59, thereby driving the cross-shaped fixing frame 511 to reciprocate up and down, and further driving the brush 512 to insert into the spraying hole 11 to the inside, and at the same time causing the brush 512 to reciprocate up and down in the spraying hole 11, so as to clean the inside of the spraying hole 11, and further dredge the blocked spraying hole 11. At the same time, it is not necessary to shut down the spraying system, improving the working efficiency of the spraying system. And through the conical block 513 fixed to the upper end of the brush 512, the impact of the liquid sprayed out from the spraying hole 11 on the brush 512 can be reduced, and the service life of the brush 512 is improved.

[0050] As Figure 5 , Figure 6 , Figure 7 shown, a discharge assembly 6 is provided at the lower end of the inner wall of the spray head 10. The discharge assembly 6 includes four uniformly distributed discharge ports 61 opened on the outer side of the lower end of the inner wall of the spray head 10, and the discharge ports 61 penetrate the lower surface of the spray head 10. A first chute 62 is opened on the inner wall of each of the four discharge ports 61. A slide bar 63 is slidably connected inside each of the four first chutes 62. A through-hole 64 is opened on the upper surface of each of the four slide bars 63. A first spring 65 is provided on one side of each of the four first chutes 62 close to the spraying hole 11. A second chute 66 is opened on one side of the upper end of the inner wall of the first chute 62 away from the spraying hole 11. A trapezoidal slider 67 is slidably connected inside each of the second chutes 66. A third chute 68 is opened on the upper end of the inner wall of each of the second chutes 66. A first slider 69 is slidably connected inside each of the third chutes 68. Connecting rods 610 are fixedly connected between each of the four first sliders 69 and each of the four trapezoidal sliders 67. A convex block 611 is fixedly connected to the outer circular surface of each of the first sliders 69, and one end of the convex block 611 extends into the second annular chute 58. A second spring 612 is provided on the upper surface of each of the first sliders 69.

[0051] As Figure 4 , Figure 6 , Figure 7 , Figure 8As shown, a monitoring component 7 is provided on the inner circular surface of the sprinkler head 10, and four evenly distributed No. 4 slide grooves 71 are opened on the inner circular surface of the monitoring component 7 below the impeller 53, and the four No. 4 slide grooves 71 are respectively located directly above the four No. 3 slide grooves 68, and the four No. 4 slide grooves 71 are slidably connected to the inside of the four No. 4 slide grooves 71, and one end of the four No. 1 straight rods 72 is commonly fixedly connected to a floating block 73, and the lower side of the outer circular surface of the four No. 1 straight rods 72 away from the floating block 73 is fixedly connected to a No. 2 straight rod 74, and the lower ends of the four No. 2 straight rods 74 extend to the inside of the four No. 3 slide grooves 68, respectively, and the lower ends of the four No. 2 straight rods 74 are fixedly connected to the inside of the four No. 3 slide grooves 68, and the lower ends of the four No. 2 straight rods 74 are fixedly connected to the upper surfaces of the four No. 1 sliding blocks 69, respectively.

[0052] In the above embodiment, the impeller 53 is driven to rotate by the liquid flowing downward in the spray head 10, thereby driving the brush 512 to be inserted into the spray hole 11, and at the same time, the brush 512 is reciprocated up and down in the spray hole 11, so as to clean the inside of the spray hole 11 and then unclog the blocked spray hole 11. However, when the brush 512 is inserted into the spray hole 11, the amount of liquid sprayed from the spray hole 11 is reduced, thereby reducing the amount of liquid sprayed from the spray head 10, thereby reducing the working efficiency and use effect of the spray system. Therefore, the discharge assembly 6 is provided, and when the brush 512 moves upward and is inserted into the spray hole 11 to the inside, the protrusion 611 is driven upward by the installation slider 510, and the No. 1 slider 69 is driven to move upward in the No. 3 slide groove 68 at the same time, and then the trapezoidal slider 67 is driven to move upward in the No. 2 slide groove 66 by the connecting rod 610, and then the No. 1 spring 65 drives the slide bar 63 to move in the direction of the trapezoidal slider 67 in the No. 1 slide groove 62, so that the through hole 64 coincides with the discharge port 61, and the liquid in the spray head 10 can be sprayed out from the discharge port 61, thereby increasing the spraying amount of the liquid sprayed from the spray head 10, and further improving the working efficiency and use effect of the spray system, and the No. 2 spring 612 can drive the No. 1 slider 69 to move downward, so that the No. 1 slider 69 is inserted into the No. 1 slide groove 62, thereby driving the slide bar 63 to move in the direction of the spray hole 11, so that the through hole 64 and the discharge port 61 are staggered, and the slide bar 63 is reset.

[0053] In the above embodiments, the downward flow of the liquid in the spray head 10 drives the impeller 53 to rotate, thereby driving the brush 512 to insert into the spray hole 11 to the inside, and at the same time causing the brush 512 to reciprocate up and down in the spray hole 11, so as to clean the inside of the spray hole 11, and then dredge the blocked spray hole 11. However, when the spray hole 11 is blocked, the liquid in the spray head 10 is difficult to flow downward, so it is difficult to drive the movement of the brush 512, reducing the practicability of the through-hole assembly 5. Therefore, a monitoring assembly 7 is provided. When the spray hole 11 is blocked and the liquid in the spray head 10 cannot flow downward, the buoyancy of the floating block 73 itself drives the floating block 73 to move upward, and at the same time drives the first straight rod 72 to move upward in the fourth chute 71, thereby driving the second straight rod 74 to move upward, and then driving the first slider 69 to move upward through the connecting rope 75, so as to start the discharge assembly 6, making the liquid in the spray head 10 flow downward and spray out from the discharge port 61, and then starting the through-hole assembly 5, improving the practicability of the through-hole assembly 5. Then, because the liquid in the spray head 10 flows downward, it drives the floating block 73 to move downward, and at the same time drives the second straight rod 74 to move downward, resetting the floating block 73 for the reuse of the monitoring assembly 7. And the connecting rope 75 itself has the flexibility of movement, so when the second straight rod 74 moves downward, it will not drive the first slider 69 to move downward, thus ensuring the normal use of the discharge assembly 6.

[0054] As Figure 9 , Figure 10 , Figure 11 As shown, a control assembly 8 is provided between the bevel gear 54 and the reciprocating lead screw 55. Installation grooves 81 are respectively opened at the lower ends of the inner walls of the rotating grooves 51 below the two bevel gears 54. Fifth chutes 84 are respectively opened on the lower surfaces of the two bevel gears 54. Fourth sliders 85 are respectively slidably connected inside the two fifth chutes 84. Third springs 86 are respectively arranged on the upper surfaces of the two fourth sliders 85. Third sliders 83 are respectively slidably connected inside the two installation grooves 81, and the two third sliders 83 are respectively fixedly connected to the lower surfaces of the two fourth sliders 85. Second sliders 82 are respectively slidably connected below the third sliders 83 inside the two installation grooves 81, and the two second sliders 82 are respectively fixedly connected to the upper ends of the two reciprocating lead screws 55. Ratchets 87 are respectively fixedly connected to the upper surfaces of the two second sliders 82 and the lower surfaces of the third sliders 83. Limit rings 88 are respectively fixedly connected to the upper sides of the outer circles of the two third sliders 83. Moving rings 89 are respectively slidably connected to the outer circles of the two third sliders 83, and the moving rings 89 are located below the limit rings 88.

[0055] As Figure 9 , Figure 10 , Figure 11As shown in the figure, on one side of the lower ends of the inner walls of the two mounting grooves 81 close to the fourth chute 71, connection grooves 811 are respectively formed. Inside the two connection grooves 811, rotating rods 812 are rotatably connected, and one ends of the rotating rods 812 extend into the mounting grooves 81 and are located below the moving ring 89. On one side of the inner walls of the two connection grooves 811 close to the fourth chute 71, sixth chutes 810 are respectively formed, and the sixth chutes 810 are located directly above the fourth chute 71. Inside the two sixth chutes 810, L-shaped rods 813 are slidably connected, and the lower ends of the two L-shaped rods 813 extend into the fourth chute 71 and are fixedly connected to the first straight rod 72. The other ends of the rotating rods 812 extend into the sixth chutes 810 and are located below the short handles of the L-shaped rods 813.

[0056] In the above embodiments, the downward flow of the liquid in the spray head 10 drives the impeller 53 to rotate, thereby driving the brush 512 to insert into the spray hole 11 and reciprocate up and down inside the spray hole 11, so as to clean the inside of the spray hole 11 and dredge the blocked spray hole 11. However, because the brush 512 reciprocates up and down in the spray hole 11, the brush 512 and the inner wall of the spray hole 11 rub against each other, greatly accelerating the wear rate of the brush 512 and reducing the service life of the brush 512. Therefore, the control component 8 is provided. When the liquid flows downward in the spray head 10, it will push the floating block 73 downward, and at the same time drive the first straight rod 72 downward, thereby driving the L-shaped rod 813 to move downward in the sixth chute 810, and then driving the other end of the rotating rod 812 downward. And the L-shaped rod 813 rotates in the sixth chute 810, so that one end of the L-shaped rod 813 moves upward, thereby driving the moving ring 89 to move upward in the installation groove 81, and then driving the third slider 83 to move upward through the limiting ring 88, so that the third slider 83 moves away from the second slider 82, so that the ratchets 87 on the third slider 83 and the second slider 82 are separated from each other, so that the downward flow of the liquid in the spray head 10 drives the impeller 53 to rotate, and then drives the bevel gear 54 to rotate through the annular bevel gear 52. However, because the third slider 83 moves away from the second slider 82, the bevel gear 54 cannot drive the reciprocating lead screw 55 to rotate, so that the brush 512 cannot be driven to insert into the spray hole 11 and reciprocate up and down. When the spray hole 11 is blocked and the liquid cannot flow downward in the spray head 10, the floating block 73 moves upward under the action of its own buoyancy, and at the same time drives the first straight rod 72 upward, thereby driving the L-shaped rod 813 upward, and then driving the fourth slider 85 to move downward in the fifth chute 84 through the third spring 86, and at the same time driving the third slider 83 downward, so that the third slider 83 approaches the second slider 82, so that the ratchets 87 on the third slider 83 and the second slider 82 are engaged with each other, and then the bevel gear 54 drives the reciprocating lead screw 55 to rotate, so as to drive the brush 512 to insert into the spray hole 11 and reciprocate up and down. When the spray hole 11 is not blocked, the brush 512 stops moving, so that the brush 512 cannot rub against the inner wall of the spray hole 11. When the spray hole 11 is blocked, the brush 512 inserts into the spray hole 11 and reciprocates up and down to clean the spray hole 11, reducing the wear rate of the brush 512, thereby increasing the service life of the brush 512.

[0057] Such as Figure 3 , Figure 6 , Figure 7 , Figure 12As shown, a rotating assembly 9 is provided on the outer circumferential surface of the eight mounting sliders 510. The rotating assembly 9 includes third gears 98 fixedly connected to the lower sides of the outer circumferential surfaces of the eight mounting sliders 510 respectively. T-shaped rotating grooves 99 are formed on the upper surfaces of the eight mounting sliders 510. T-shaped rotating blocks 910 are fixedly connected to the lower surfaces of the eight connecting rings 59, and the eight T-shaped rotating blocks 910 are respectively rotatably connected to the interiors of the eight T-shaped rotating grooves 99. A sleeve 91 is sleeved on the outer circumferential surface of the main water pipe 2, and the sleeve 91 is fixedly connected to the lower surface of the treatment tank body 1. The main water pipe 2 is rotatably connected to the interior of the sleeve 91. An annular gear 97 is fixedly connected to the upper side of the outer circumferential surface of the sleeve 91, and the annular gear 97 is meshed with all the eight third gears 98.

[0058] As Figure 1 As shown, a mounting frame 92 is fixedly connected to the position of the lower surface of the treatment tank body 1 below the sleeve 91. A water inlet pipe 93 is rotatably connected to the lower surface of the main water pipe 2 passing through the lower surface of the mounting frame 92. A first gear 94 is fixedly connected to the position of the outer circumferential surface of the main water pipe 2 inside the mounting frame 92. A motor 95 is fixedly connected to the side of the lower surface of the mounting frame 92 away from the first gear 94. The output end of the motor 95 penetrates into the mounting frame 92 and is fixedly connected to a second gear 96, and the second gear 96 is meshed with the first gear 94.

[0059] In the above embodiments, the downward flow of the liquid in the spray head 10 drives the impeller 53 to rotate, thereby driving the brush 512 to reciprocate up and down inside the spray hole 11, and then cleaning the inside of the spray hole 11 to dredge the blocked spray hole 11. However, by reciprocating the brush 512 up and down inside the spray hole 11 to clean the spray hole 11, since there are certain gaps between the bristles of the brush 512, the cleaning effect of the brush 512 on the spray hole 11 is poor, reducing the use effect of the through-hole assembly 5. Therefore, a rotating assembly 9 is provided. The motor 95 is started to drive the second gear 96 to rotate inside the mounting frame 92, thereby driving the first gear 94 to rotate, and then driving the main water pipe 2 to rotate inside the sleeve 91. At the same time, the spray head 10 drives the mounting slider 510 to rotate around the sleeve 91, thereby driving the third gear 98 to rotate around the sleeve 91. And the ring gear 97 is fixed. Then, through the rotational connection between the T-shaped rotating block 910 and the T-shaped rotating groove 99, when the third gear 98 rotates around the sleeve 91, the third gear 98 rotates itself at the same time, thereby driving the mounting slider 510 to rotate itself. Then, the brush 512 is driven to rotate itself through the cross-shaped fixing frame 511, so that when the brush 512 reciprocates up and down inside the spray hole 11, the brush 512 can rotate itself, so that the bristles of the brush 512 can contact the inside of the spray hole 11 more comprehensively, so that the brush 512 can clean the inside of the spray hole 11 more comprehensively, improving the use effect of the through-hole assembly 5. And by rotating the spray head 10 around the sleeve 91, the spray hole 11 can spray the liquid more comprehensively inside the treatment tank 1, improving the use effect of the spray system.

[0060] Usage method: The waste gas is discharged into the treatment tank 1 through the intake pipe 13. Then, an external water supply device adds liquid to the main water pipe 2, and then enters the spray head 10, and finally sprays out through the spray holes 11, so that the liquid fully contacts the waste gas and treats the pollutants in the waste gas. When the spray hole 11 is blocked, the liquid in the spray head 10 is difficult to flow downward. Thus, the monitoring assembly 7 is started. The floating block 73 moves upward to drive the first slider 69 to move upward. The discharge assembly 6 is started so that the liquid in the spray head 10 can flow downward and spray out from the discharge port 61, thereby driving the impeller 53 to rotate. At the same time, the control assembly 8 is started to drive the third slider 83 to move toward the second slider 82, so that the ratchets 87 on the third slider 83 and the second slider 82 are engaged with each other, so that the bevel gear 54 drives the reciprocating screw rod 55 to rotate, and then the through-hole assembly 5 is started to drive the brush 512 to reciprocate up and down inside the spray hole 11. Then, the rotating assembly 9 is started to drive the brush 512 to rotate itself to clean the blocked spray hole 11.
