Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment equipment, and particularly relates to an atomization treatment device for waste gas in fiberboard production. Background Art

[0002] During the production process of fiberboard, various waste gases are generated, mainly including formaldehyde, particulate matter, etc. These waste gases not only pollute the environment but also may pose a hazard to the health of workers. Therefore, effective treatment of waste gas during the fiberboard production process is very important. In the prior art, an atomization treatment device is used to treat waste gas, that is, the waste gas is first filtered and then water is sprayed to mix water droplets with the dust in the waste gas to achieve the effect of treating the waste gas. However, after some existing waste gas atomization treatment devices are used for long-term filtration of particulate matter in the waste gas, blockage is likely to occur, resulting in pipeline blockage, thereby reducing the filtration effect and ultimately leading to poor waste gas treatment effect. Summary of the Invention

[0003] Aiming at the above-mentioned existing technical deficiencies, the purpose of the present invention is to provide an atomization treatment device for waste gas in fiberboard production, which has the advantages of improving the filtration effect and avoiding blockage.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an atomization treatment device for waste gas in fiberboard production, including: A spray tower body; A partition plate that divides the interior of the spray tower body into an upper cavity and a lower cavity. The upper cavity and the lower cavity are connected through a plurality of air pipes provided on the partition plate. A drain pipe is provided on the upper cavity, and an intake pipe is provided on the lower cavity; A spray component provided in the upper cavity; A gas filtration component provided in the lower cavity; Among them, the spray component includes a central column body provided at the top of the upper cavity. A plurality of spray pipes are circumferentially hinged on the outer peripheral wall of the central column body. A plurality of nozzles are provided on the outer peripheral wall of the spray pipe. The spray pipe is connected to a water tank provided outside the spray tower body through a hose; The gas filtration component includes opening grooves provided on two opposite side walls of the lower cavity. A plurality of filter plate boxes are horizontally and movably inserted through the opening grooves. Adjacent two filter plate boxes are hinged through a rotating shaft. A plurality of filter plate bodies are movably inserted into the filter plate boxes.

[0005] Preferably, the cross-section of the spray pipe is semi-circular. The rectangular surface of the spray pipe is in contact with the outer peripheral wall of the central column body. The nozzles are embedded in the rectangular surface of the spray pipe, and the nozzles are distributed in a matrix on the rectangular surface of the spray pipe, which is convenient for spraying the waste gas and separating and removing suspended particulate matter and the like in the waste gas.

[0006] Preferably, the spray pipe is rotationally hinged on the outer peripheral wall of the central column body through a rotating shaft with a torsion spring. A pushing cylinder is arranged at the top of the upper cavity. A circular filter plate is arranged on the piston rod of the pushing cylinder. The circular filter plate is movably sleeved outside the spray pipe, so that it is convenient to move the circular filter plate to different positions outside the spray pipe under the action of the pushing cylinder as needed, and further adjust the angle of the spray pipe on the outer peripheral wall of the central column body, thereby achieving different spraying effects.

[0007] Preferably, the distances from the arc surfaces of the respective spray pipes to the axis of the central column body are all the same, and the diameter of the circle formed by the arc surfaces of the respective spray pipes is adapted to the inner diameter of the circular filter plate. It is possible to move the circular filter plate to different positions outside the spray pipe under the action of the pushing cylinder, and further adjust the angle of the spray pipe on the outer peripheral wall of the central column body, thereby achieving different spraying effects.

[0008] Preferably, the top and bottom surfaces of the filter plate box are both open. The rotating shaft is arranged at the bottom of the side wall of the filter plate box. The bottoms of two adjacent filter plate boxes are rotationally connected through the rotating shaft. The side wall of the filter plate box away from the rotating shaft is open, and a cover body is movably arranged on the open side wall of the filter plate box, which is convenient for the waste gas to enter through the bottom surface of the filter plate box, and after being filtered by the filter plate body, it is discharged from the top surface of the filter plate box.

[0009] Preferably, a plurality of filter plate bodies are movably inserted into the filter plate box. A plurality of plate grooves corresponding to the filter plate bodies one by one are arranged in the filter plate box from top to bottom. The filter plate bodies are respectively horizontally and movably inserted into the plate grooves at corresponding positions, so that the waste gas is filtered by a plurality of filter plate bodies, improving the quality after emission; at the same time, it is also convenient to replace the used filter plate bodies.

[0010] Preferably, sealing grooves are arranged on both opposite sides of the top opening of the filter plate box. Sealing rods corresponding to the sealing grooves one by one are arranged on the inner wall of the bottom of the opening groove, and the tops of the sealing rods are connected to the inner wall of the bottom of the opening groove through a plurality of springs. The bottoms of the sealing rods are respectively movably clamped into the sealing grooves at corresponding positions, which can prevent the waste gas from leaking from the lower cavity.

[0011] Preferably, the length direction of the sealing groove is the same as the length direction of the sealing rod. The bottom of the sealing rod is arc-shaped, and the diameter of the arc shape at the bottom of the sealing rod is greater than the width of the sealing groove, which is beneficial to improving the sealing performance between the sealing rod and the sealing groove.

[0012] Preferably, the distance between the two opening grooves is less than the length of the filter plate box, which is convenient for the filter plate box to maintain a stable position after passing through the two opening grooves.

[0013] Preferably, box brackets are also provided on the two opposite outer side walls of the lower cavity. The box brackets are horizontally arranged at the bottom of the opening of the opening groove, facilitating the pulling out of the used filter plate box onto one of the box brackets for support. At the same time, the other box bracket can support the unused filter plate box for subsequent use.

[0014] The beneficial effects of the present invention are as follows: 1. Through multiple filter plate boxes that are rotatably connected to each other, the filter plate boxes can be successively passed through the opening groove into the lower cavity one by one according to the filtration needs, enabling the waste gas to pass through the bottom opening of the filter plate box and then be successively filtered through each filter plate body, improving the filtration effect, avoiding the blockage of the filter plate body, and ultimately improving the quality of the waste gas after emission.

[0015] 2. Also, according to the spraying needs, the pushing cylinder can be activated to move the circular ring filter plate outside the spraying pipe. The inner circle of the circular ring filter plate successively abuts against different positions in the length direction of the spraying pipe, enabling the spraying pipe to rotate around the rotating shaft with a torsion spring as the axis, thereby adjusting the angle between the spraying pipe and the central column body, making the nozzles on the spraying pipe face different directions, and thus achieving different spraying ranges and effects.

[0027] 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.

[0028] Embodiment 1 As Figures 1 to 5 、 Figure 9As shown in the figure, the present invention provides an atomization treatment device for waste gas in fiberboard production, including a spray tower body 1; a partition plate 11 divides the interior of the spray tower body 1 into an upper cavity 12 and a lower cavity 13, and the upper cavity 12 and the lower cavity 13 are connected through a plurality of ventilation pipes 3 provided on the partition plate 11. A drain pipe 121 is provided on the upper cavity 12, and an intake pipe 131 is provided on the lower cavity 13; a spray assembly 2 is provided in the upper cavity 12; a gas filtration assembly 4 is provided in the lower cavity 13; the spray assembly 2 includes a central column body 21 provided at the top inside the upper cavity 12. A plurality of spray pipes 22 are circumferentially hinged on the outer peripheral wall of the central column body 21. A plurality of nozzles 23 are provided on the outer peripheral wall of the spray pipe 22. The spray pipe 22 is connected to a water tank provided outside the spray tower body 1 through a hose; the gas filtration assembly 4 includes opening grooves 41 provided on two opposite side walls of the lower cavity 13. A plurality of filter plate boxes 42 are horizontally movably penetrated in the opening grooves 41. Adjacent two filter plate boxes 42 are hinged through a rotating shaft 43. A plurality of filter plates 44 are movably inserted into the filter plate boxes 42.

[0029] The waste gas enters the lower cavity 13 through the intake pipe 131 on the lower cavity 13, and after being sequentially filtered by a plurality of filter plates 44 in the filter plate boxes 42 (the filter plates 44 can be made of activated carbon materials and can adsorb harmful substances such as formaldehyde and benzene in the waste gas), it then enters the upper cavity 12 through a plurality of ventilation pipes 3 on the partition plate 11, and is subjected to spray treatment under the action of the spray pipes 22 and the nozzles 23. The sprayed waste gas can be discharged to the outside of the upper cavity 12; a discharge pipe is provided at the top of the upper cavity 12, and the sprayed waste gas can be discharged through the discharge pipe (a water tank filled with filtered water can also be provided outside the spray tower body 1. One end of the discharge pipe away from the upper cavity 12 is inserted into the water tank, and the waste gas can be filtered again by the filtered water and then discharged to improve the effect after waste gas treatment).

[0030] The central column body 21 can be provided at the top inside the upper cavity 12 through a support column provided on the partition plate 11.

[0031] Embodiment 2 On the basis of Embodiment 1, as Figures 1 to 4As shown, the cross-section of the spray pipe 22 is semi-circular. The rectangular surface of the spray pipe 22 is in contact with the outer peripheral wall of the central column 21. The spray nozzles 23 are embedded in the rectangular surface of the spray pipe 22, and the spray nozzles 23 are distributed in a matrix on the rectangular surface of the spray pipe 22. The spray pipe 22 is rotationally hinged on the outer peripheral wall of the central column 21 through a rotating shaft 221 with a torsion spring. A pushing cylinder 14 is arranged at the top of the upper cavity 12. A circular ring filter plate 15 is arranged on the piston rod of the pushing cylinder 14. The circular ring filter plate 15 is movably sleeved outside the spray pipe 22. The distances from the arc surfaces of the respective spray pipes 22 to the axis of the central column 21 are all the same, and the diameter of the circle formed by the arc surfaces of the respective spray pipes 22 is adapted to the inner diameter of the circular ring filter plate 15.

[0032] According to the spraying requirement, the pushing cylinder 14 can be started to move the circular ring filter plate 15 outside the spray pipe 22. When the circular ring filter plate 15 continues to move through the position of the rotating shaft 221 with a torsion spring, at this time, the inner circle of the circular ring filter plate 15 sequentially abuts against different positions in the length direction of the spray pipe 22, so that the spray pipe 22 can rotate around the rotating shaft 221 with a torsion spring as the axis, thereby adjusting the included angle between the spray pipe 22 and the central column 21, enabling the spray nozzles 23 on the spray pipe 22 to face different directions, and further achieving different spraying ranges and effects (when spraying is not required, the circular ring filter plate 15 can be moved to the outside of the end of the spray pipe 22 far from the rotating shaft 221 with a torsion spring. At this time, the rectangular surface of the spray pipe 22 is in contact with the outer peripheral wall of the central column 21, thereby preventing the suspended particulate matter in the waste gas from accumulating on the spray nozzles 23).

[0033] After using the spray pipe 22 to spray the waste gas, the pushing cylinder 14 can be simultaneously used to move the circular ring filter plate 15 outside the spray pipe 22 in the direction close to the partition plate 11, so that the circular ring filter plate 15 can push the suspended particulate matter in the upper cavity 12 in the direction close to the partition plate 11, avoiding or reducing the discharge of the suspended particulate matter in the upper cavity 12 along with the treated waste gas.

[0034] Embodiment III On the basis of Embodiment I, as Figure 1 、 Figures 5 to 6 shown, both the top and bottom surfaces of the filter plate box 42 are open. The rotating shaft 43 is arranged at the bottom of the side wall of the filter plate box 42. The bottoms of two adjacent filter plate boxes 42 are rotationally connected through the rotating shaft 43. The side wall of the filter plate box 42 far from the rotating shaft 43 is open, and a cover body 421 is movably arranged on the open side wall of the filter plate box 42. A plurality of filter plate bodies 44 are movably inserted into the filter plate box 42. A plurality of plate body grooves 422 corresponding to the filter plate bodies 44 one by one are arranged in the filter plate box 42 from top to bottom. The filter plate bodies 44 are respectively horizontally and movably inserted into the plate body grooves 422 at corresponding positions.

[0035] The waste gas enters the lower cavity 13 through the intake pipe 131 on the lower cavity 13, and then passes through each filter plate body 44 through the bottom opening of the filter plate box 42 for sequential filtration, improving the quality of the waste gas after emission, and then is discharged through the top opening of the filter plate box 42 (entering the upper cavity 12 from the lower cavity 13 through the ventilation pipe 3).

[0036] When the filter plate box 42 in the lower cavity 13 needs to be replaced after being used for a period of time, the filter plate box 42 in the lower cavity 13 can be moved to the outside of the lower cavity 13, and at the same time, the filter plate box 42 outside the lower cavity 13 can be passed through the opening groove 41 into the lower cavity 13 (at this time, the used filter plate box 42 can be located outside the lower cavity 13, which is convenient for inspecting and replacing the filter plate body 44 in the filter plate box 42).

[0037] When it is necessary to inspect and replace the filter plate body 44, the filter plate box 42 can be first moved to the outside of the lower cavity 13, and the cover body 421 on the side wall of the opening of the filter plate box 42 can be opened to inspect the filter plate body 44 or the filter plate body 44 can be taken out from the plate body groove 422 for replacement and installation.

[0038] Embodiment Four On the basis of Embodiment One, as Figure 1 、 Figures 5 to 7 shown, sealing grooves 5 are provided on both opposite sides of the top opening of the filter plate box 42, sealing rods 51 corresponding to the sealing grooves 5 one by one are provided on the inner wall of the bottom of the opening groove 41, and the top of the sealing rod 51 is connected to the inner wall of the bottom of the opening groove 41 through a plurality of springs 52. The bottom of the sealing rod 51 is respectively movably clamped into the sealing grooves 5 at the corresponding positions; the length direction of the sealing groove 5 is the same as the length direction of the sealing rod 51, the bottom of the sealing rod 51 is arc-shaped, and the diameter of the arc shape at the bottom of the sealing rod 51 is greater than the width of the sealing groove 5; the distance between the two opening grooves 41 is less than the length of the filter plate box 42.

[0039] When the filter plate box 42 is moved into the lower cavity 13 for use, at this time, the opposite ends of the filter plate box 42 can respectively penetrate through the two opening grooves 41; at the same time, the arc-shaped bottom of the sealing rod 51 can be clamped into the sealing groove 5 at the corresponding position (the sealing rod 51 is closely attached to the sealing groove 5 under the action of the spring 52), which is beneficial to improving the sealing performance between the sealing rod 51 and the sealing groove 5 and avoiding the leakage of waste gas from the position of the sealing groove 5.

[0040] Embodiment Five On the basis of Embodiment One, as Figure 1 、 Figures 5 to 6 、 Figure 8As shown, box brackets 6 are also provided on the two opposite outer sidewalls of the lower cavity 13, and the box brackets 6 are horizontally arranged at the bottom of the opening of the opening groove 41; since the bottoms of the plurality of filter plate boxes 42 are rotationally connected by a rotating shaft 43, when using one of the filter plate boxes 42 (i.e., the filter plate box 42 in use is located in the lower cavity 13), at this time, the filter plate boxes 42 at the adjacent two ends of the filter plate box 42 in use (i.e., the filter plate boxes 42 at the two ends of the filter plate box 42 in use are respectively: the used filter plate box 42 and the unused filter plate box 42) can be respectively located on the two box brackets 6, which is convenient for supporting by the box brackets 6.
