Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, and in particular to a dust removal waste gas treatment device using a spray tower. Background Technology

[0002] A spray tower dust removal and exhaust gas treatment device is an environmental protection equipment that uses liquid spraying to contact exhaust gas to purify the gas. It is mainly used for industrial exhaust gas treatment. Its working principle is to atomize water or chemical solution through the spray system and make full contact with dust or harmful gas, so that pollutants are absorbed, dissolved or chemically reacted by liquid droplets. Then, the gas-liquid contact area is increased by the packing layer to improve the purification efficiency. Finally, the liquid droplets are removed by the demister layer and the gas is discharged in compliance with the standards.

[0003] Existing dust removal and exhaust gas treatment devices for spray towers lack the functions of observation window defogging and nozzle cleaning. The lack of these functions may lead to delayed maintenance response. Daily inspections rely on the observation window to record parameters such as spray liquid flow rate and packing integrity. Fog can obscure the observation window, increasing the difficulty of manual inspection, and nozzle blockage can cause uneven spraying or complete failure.

[0004] Therefore, given the lack of observation window defogging and nozzle cleaning functions in the existing spray tower dust removal and exhaust gas treatment devices, problems such as fog obscuring the observation window leading to increased difficulty in manual inspection, and nozzle blockage causing uneven spraying or complete failure, there is an urgent need to design a new type of spray tower dust removal and exhaust gas treatment device. Utility Model Content

[0005] In order to overcome the lack of observation window defogging and nozzle cleaning functions in existing dust removal and exhaust gas treatment devices, problems may arise such as fog obscuring the observation window, which increases the difficulty of manual inspection, and nozzle blockage leading to uneven spraying or complete failure.

[0006] The technical solution of this utility model is as follows: a dust removal and exhaust gas treatment device for a spray tower, including a main chamber; it also includes a lifting frame, a drive motor, a lead screw, a slider, a mounting bracket, a heater, a movable frame, a waterproof motor, a lead screw, a slider, and a brush plate. The lifting frame is located on the right side of the front exterior of the main chamber. The drive motor is installed on the upper surface of the lifting frame. The output end of the drive motor passes through the upper surface of the lifting frame and is connected to the lead screw. The lower surface of the lead screw is rotatably connected to the lower inner surface of the lifting frame. The outer surface of the lead screw is threaded through and connected to the slider. Two symmetrical mounting brackets are connected to the left surface of the slider. A heater is connected between the two mounting brackets. Movable frames are located in the middle and upper parts of the interior of the main chamber. A waterproof motor is installed on the left side of the rear surface of the movable frame. The output end of the waterproof motor passes through the rear surface of the movable frame and is connected to the lead screw. The outer surface of the lead screw is threaded through and connected to the slider. A brush plate is located on the right surface of the slider.

[0007] Preferably, by setting a drive motor, the drive motor drives the lead screw to rotate. When the lead screw rotates, the rotation of the slider is restricted by the lifting frame, thereby moving the slider. When the slider moves, the heating fan moves through the mounting bracket. When the inner surface of the observation window is fogged up and cannot be seen, the drive motor is activated, causing the heating fan to move up and down to defog different observation windows, thus achieving the purpose of cleaning the internal fog. By setting a waterproof motor, the waterproof motor drives the lead screw to rotate. When the lead screw rotates, the rotation of the slider is restricted by the moving frame, thereby moving the slider. When the slider moves, the brush plate moves, cleaning the dust inside the nozzle, thus achieving the purpose of cleaning the nozzle. This solves the problem that the existing spray tower dust removal and exhaust gas treatment device lacks the functions of observation window defogging and nozzle cleaning. The lack of these functions may lead to delayed maintenance response. Daily inspections rely on the observation window to record parameters such as spray liquid flow rate and packing integrity. Fog obstructing the observation window increases the difficulty of manual inspection, and nozzle blockage leads to uneven spraying or complete failure.

[0008] Preferably, a limit rod is provided on the right side of the inner front surface of the movable frame, and a slider three is slidably connected through the outer surface of the limit rod. The left surface of the slider three is connected to the right surface of the brush plate.

[0009] Preferably, a transfer compartment is located on the lower rear side of the outer surface of the main compartment. A water pump is installed on the upper surface of the transfer compartment, and a pipe is installed on the upper surface of the water pump. Support frames are installed on the front side of the inner surface of the main compartment above the two movable frames. One end of a spray pipe is installed on the rear surface of each of the two support frames, and the other end of the spray pipe passes through the rear side of the inner surface of the main compartment and is connected to the pipe.

[0010] Preferably, the main compartment has perforated panels in the middle and lower upper part, and the upper surface of the two perforated panels is filled with filler.

[0011] Preferably, observation frames are provided on the front middle and upper sides of the main compartment, and glass is installed inside both observation frames.

[0012] Preferably, each of the left surfaces of the two observation frames is provided with a hinge at one end, and a baffle is connected to the other end of the hinge.

[0013] Preferably, a second pipe is provided on the lower front side of the main compartment, and a second water pump is connected to the front surface of the second pipe, with a valve port provided on the front surface of the second water pump.

[0014] Preferably, the lower surface of the main compartment is provided with three circumferentially distributed support legs, and the lower surface of each of the three support legs is provided with casters.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting up a drive motor, the operation of the drive motor drives the lead screw to rotate. With the help of the rotational constraint mechanism formed by the lifting frame on the slider, the rotational motion of the lead screw is converted into the linear displacement of the slider. When fog appears inside the observation window and affects visibility, the drive motor is started to make the slider reciprocate along the lead screw. Through the linkage of the mounting bracket and the warm air fan, multi-height position adjustment can be achieved. Directional defogging operation is performed for different levels of observation windows to achieve the purpose of clearing the internal fog. This solves the problem that the existing dust removal and exhaust gas treatment device of the spray tower lacks the function of observation window defogging. Without this function, maintenance response may be delayed. Daily inspections rely on the observation window to record parameters such as spray liquid flow and packing integrity. However, the fog obscures the observation window, which increases the difficulty of manual inspection.

[0017] 2. By setting up a waterproof motor, the waterproof motor drives the lead screw to rotate. The moving frame forms a motion limiting structure for the slider, converting the rotational kinetic energy of the lead screw into the linear motion of the slider. This drives the rigidly connected brush plate to reciprocate along the nozzle axis, effectively removing impurities accumulated inside the spray holes. This achieves the purpose of cleaning the nozzles, thus solving the problem of the lack of nozzle cleaning function in existing dust removal and exhaust gas treatment devices. Without this function, problems such as uneven spraying or complete failure due to nozzle clogging may occur. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-5This utility model provides an embodiment: a dust removal and exhaust gas treatment device for a spray tower, including a main chamber 1; it also includes a lifting frame 2, a drive motor 3, a lead screw 4, a slider 5, a mounting bracket 6, a heater 7, a movable frame 8, a waterproof motor 9, a second lead screw 10, a second slider 11, and a brush plate 12. The lifting frame 2 is located on the right side of the outer surface of the main chamber 1. The drive motor 3 is mounted on the upper surface of the lifting frame 2. The output end of the drive motor 3 passes through the upper surface of the lifting frame 2 and is connected to the lead screw 4. The lower surface of the lead screw 4 is rotatably connected to the lower inner surface of the lifting frame 2. The outer surface of the lead screw 4 is threaded through and connected to the slider 5. Two symmetrical mounting brackets 6 are connected to the left surface of the slider 5, and a heater 7 is connected between the two mounting brackets 6. Movable frames 8 are located in the middle and upper parts of the interior of the main chamber 1. A waterproof motor 9 is mounted on the left side of the rear surface of the movable frame 8. The output end of the waterproof motor 9 passes through the rear surface of the movable frame 8 and is connected to the lead screw 10. A second rod 10 has a threaded connection on its outer surface to a second slider 11. A brush plate 12 is mounted on the right surface of the second slider 11. A drive motor 3 drives a first screw 4 to rotate. The rotation of the first screw 4 is restricted by a lifting frame 2, causing the slider 5 to move. The movement of the slider 5, in turn, moves a heater 7 via a mounting bracket 6. When fog obscures the inner surface of the observation window, the drive motor 3 is activated, causing the heater 7 to move up and down to defog different observation windows, thus clearing the internal fog. A waterproof motor 9 drives a second screw 10 to rotate. The rotation of the second screw 10 is restricted by a moving frame 8, causing the slider 11 to move. The movement of the slider 11 moves the brush plate 12, which cleans the dust inside the nozzle, thus cleaning the nozzle.

[0026] Please see Figures 3-5In this embodiment, a limit rod 13 is provided on the right side of the inner front surface of the movable frame 8. A slider 14 is slidably connected through the outer surface of the limit rod 13. The left surface of the slider 14 is connected to the right surface of the brush plate 12. By setting the slider 14, since the slider 14 is connected to the brush plate 12, the brush plate 12 moves and drives the slider 14 to move. The limit rod 13 restricts the movement of the slider 14, thereby indirectly strengthening the rotation restriction of the slider 11, so as to make the brush plate 12 more stable when it moves. A transfer chamber 15 is provided at the lower rear side of the outer surface of the main chamber 1. A water pump 16 is installed on the upper surface of the transfer chamber 15. A pipe 17 is provided on the upper surface of the water pump 16. A support frame 19 is provided on the front side of the inner surface of the main chamber 1 above the two movable frames 8. Each of the two support frames 19 has a spray pipe 18 installed on one end of its rear surface. The other end of the spray pipe 18 passes through the rear side of the inner surface of the main chamber 1 and is connected to pipe 17. A water pump 16 is installed so that when the water pump 16 is running, it pumps the water source filtered by the external filter into pipe 17. Then, pipe 17 introduces the water source into the two spray pipes 18. Finally, the spray pipes 18 spray the water source out, thereby achieving the purpose of spraying. The main chamber 1 has perforated plates 20 installed in the middle and lower upper part of its interior. The upper surface of the two perforated plates 20 is equipped with filler 21. By setting the perforated plates 20, the process of the sprayed liquid falling is not blocked, and the filler 21 is provided with installation space. The filler 21 is used to filter harmful substances in the exhaust gas, thereby achieving the purpose of filtering the gas.

[0027] Please see Figures 1-5In this embodiment, observation frames 22 are provided on the front middle and upper sides of the main chamber 1. Glass 23 is installed inside each observation frame 22. The glass 23 allows staff to directly observe the spraying conditions inside the main chamber 1, enabling data recording and monitoring of internal components, thus assisting staff in their work. A hinge 24 is provided on the left surface of each observation frame 22, with a baffle 25 connected to the other end of the hinge 24. The hinge 24 allows the baffle 25 and observation frame 22 to open and close. The baffle 25 also provides protection for the glass 23 when not in use, preventing breakage due to external force or dust accumulation on its surface, thereby preventing breakage. To prevent damage caused by external factors, a second pipe 26 is installed on the lower front side of the main chamber 1. A second water pump 27 is connected to the front surface of the second pipe 26, and a valve port 28 is installed on the front surface of the second water pump 27. When the second water pump 27 is running, it pumps the sewage inside the main chamber 1 into the valve port 28 through the second pipe 26. When the valve port 28 is opened, the sewage can be sent to an external filter for filtration, thereby achieving the purpose of sewage discharge. Three circumferentially distributed support legs 29 are installed on the lower surface of the main chamber 1. Each of the three support legs 29 is equipped with a caster wheel 30. The caster wheel 30 allows for 360-degree horizontal rotation, which enables the dust removal and exhaust gas treatment device of the spray tower to move in any direction, thereby facilitating transportation.

[0028] During operation, slider 3 14 is connected to brush plate 12. When brush plate 12 moves, it drives slider 3 14 to move. Limit rod 13 restricts the movement of slider 3 14, indirectly strengthening the rotation restriction of slider 2 11. This makes the movement of brush plate 12 more stable. Water pump 16 pumps filtered water from the external filter into pipe 17, which then introduces the water into two spray pipes 18. Finally, the spray pipes 18 spray the water out, achieving the spraying purpose. A perforated plate 20 prevents obstruction of the liquid's fall and provides installation space for filler 21, which filters harmful substances from the exhaust gas, thus achieving gas filtration. Glass 23 allows workers to clearly see the process. The system monitors the spraying conditions inside the main chamber 1, allowing for data recording and tracking of internal components to assist staff in their work. Hinges 24 enable the opening and closing of baffles 25 and the observation frame 22. Baffles 25 also provide protection for the glass 23 when not in use, preventing breakage due to external forces or dust accumulation on its surface, thus protecting it from damage. A second water pump 27 pumps wastewater from the main chamber 1 through pipe 26 to valve 28. Opening valve 28 sends the wastewater to an external filter for filtration, facilitating wastewater discharge. Casters 30 allow for 360-degree horizontal rotation, enabling the spray tower dust removal and exhaust gas treatment device to move in any direction for easy transport.

[0029] Through the above steps, by setting up a drive motor 3, the drive motor 3 drives the lead screw 4 to rotate. When the lead screw 4 rotates, the rotation of the slider 5 is restricted by the lifting frame 2, thereby driving the slider 5 to move. When the slider 5 moves, the heater 7 moves through the mounting bracket 6. When the inner surface of the observation window is fogged up and cannot be seen clearly, the drive motor 3 is activated, causing the heater 7 to move up and down to defog different observation windows, thereby achieving the purpose of clearing the internal fog. By setting up a waterproof motor 9, the waterproof motor 9 drives the lead screw 10 to rotate. When the lead screw 10 rotates, the sliding frame 8 restricts the rotation of the slider 5. The rotation restriction of block 2 11 drives slider 2 11 to move. When slider 2 11 moves, it drives brush plate 12 to move. When brush plate 12 moves, it cleans the dust inside the nozzle, thereby achieving the purpose of cleaning the nozzle. This solves the problem that the existing dust removal and exhaust gas treatment device of the spray tower lacks the functions of observation window demisting and nozzle cleaning. Without these functions, there may be a delay in maintenance response. Daily inspections rely on the observation window to record parameters such as spray liquid flow rate and packing integrity. Because the observation window is blocked by fog, it increases the difficulty of manual inspection, as well as the problem of uneven spraying or complete failure caused by nozzle blockage.
