Description

Technical Field

[0001] The utility model relates to the field of spray towers, and more specifically, to a spray tower for waste gas treatment. Background Art

[0002] In the existing spray tower, the spray liquid is sprayed from the top onto the packing and flows down along the surface of the packing; the gas is fed from the bottom of the tower and passes continuously through the voids of the packing layer in countercurrent with the liquid. On the surface of the packing, the gas-liquid contact can be carried out for purification.

[0003] However, in the actual use process, the magnitude of the airflow of the waste gas entering the tower body changes little, which means that it mostly diffuses and rises in a certain area, resulting in insufficient diffusion and insufficient contact with the upper packing. Especially in the area near the air inlet, blind spots are likely to appear, affecting the overall purification effect, and also causing the packing in the blind spot position to fail to play its corresponding role, resulting in waste. Therefore, it needs to be improved. Summary of the Utility Model

Detailed Embodiments

[0019] The technical solution of the present invention will be further described below with reference to the drawings and through specific embodiments.

[0021] The above-mentioned spray tower for waste gas treatment limits the flow of gas entering the tower body by setting an air duct to ensure that the waste gas is discharged from the exhaust port; the outer diameter of the air duct is adapted to the inner diameter of the air inlet pipe, which can strengthen the connection and support the air duct by the air inlet pipe; the exhaust gas can be blocked by setting a movable baffle inside, so that the space inside the air duct is divided, and the exhaust range of the exhaust port is changed, so that the exhaust position and range of the exhaust gas can be changed, especially near the position of the air inlet pipe; when the baffle moves back and forth, the exhaust gas can be disturbed to a certain extent, and the air flow can be effectively dispersed; in general, the movable baffle can make the gas diffuse better, reduce the contact blind area, and reduce the waste caused by insufficient utilization of fillers;

[0022] Moreover, it adopts an add-on structure, which can be assembled externally, making it convenient for the disassembly and assembly of various structural components; and it can be applied to the existing spray tower without making any changes to the original spray tower structure, which is convenient for practical application;

[0023] It should be noted that the pumping system includes a water tank for storing the spray liquid, a water pump for pressurizing and pumping the spray liquid, a diversion pipe and a nozzle for spraying; a grid is also provided inside the tower body to prevent fillers; a viewing window is also provided on the side wall of the tower body to view the internal spraying conditions and to take out and replace fillers; the above-mentioned structures are common in spray towers and will not be described in detail.

[0024] Furthermore, the wind shielding structure 300 includes a baffle 310, a lead screw 320, and a motor 330; the lead screw 320 is mounted inside the air duct 500 through a bearing, a slide seat 321 is mounted on the lead screw 320, and the baffle 310 is mounted on the slide seat 321; the motor 330 is transmission-connected to the lead screw 320 to drive the lead screw to rotate; by using the lead screw structure as a structure to drive the movement of the baffle, it is easy to realize the action of moving back and forth, and can achieve the effect of fixed-point parking, so that the baffle can be stably maintained at a desired position, which is convenient for actual adjustment applications.

[0025] Furthermore, an arc plate 520 is fixedly provided at the bottom of one end of the air duct 500, and the outer diameter of the arc plate 520 is adapted to the inner diameter of the support tube 400. The support tube 400 is sleeved on the outer side of the arc plate 520 and fixedly connected by bolts; the end of the air duct 500 is abutted against the outer wall of the end of the support tube 400; the insertion connection is adopted, which can further strengthen the connection and cooperation between the air duct and the support tube, and does not affect the installation and cooperation between the support tube and the air intake pipe;

[0026] A first partition plate 530 is fixedly disposed laterally inside the air duct 500, and is tilted downward toward the end away from the arc plate; the lead screw 320 is installed on the top surface of the first partition plate 530 through a bearing seat, and the lead screw is in a flat state; the bottom of the air duct is elevated by the first partition plate, which can facilitate the installation of the lead screw on the one hand, and reduce the internal space on the other hand, so as to better limit the movement of exhaust gas; it should be noted that the bottom of the two bearings can be made flatter by placing gaskets on them, or grooves can be set on the top of both ends of the partition plate so that the two bearing seats maintain a flat and aligned state, thereby keeping the lead screw in a horizontal state; based on this, it means that there will be a gap between the bottom of the baffle and the top surface of the first baffle plate to facilitate the backflow of the spray liquid and prevent the baffle from affecting the flow of the spray liquid.

[0027] Furthermore, the inclination angle of the first baffle does not exceed 2°, which can facilitate the spray liquid to flow to the lower inclination, and will not leave a large gap between the baffle and the air duct, so as to maintain the wind-blocking effect of the baffle and allow the incoming exhaust gas to be discharged from the desired position as much as possible;

[0028] Furthermore, a sealing gasket is fixedly provided on the end face of one end of the air guide tube close to the arc plate. After the support tube and the arc plate are docked and installed in place, the air guide tube and the support tube form a clamping and squeezing effect on the sealing gasket, forming an effective sealing fit and making the overall connection more compact.

[0029] Furthermore, one end of the lead screw 320 extends to the interior of the support tube, and a first pulley 340 is fixedly provided at the end thereof; the motor 330 is mounted on the outer wall of the support tube 400, and a second pulley 350 is fixedly provided on the output shaft of the motor 330; a perforation is provided on the outer wall of the support tube 400 corresponding to the first pulley, and the second pulley 350 is connected to the first pulley 340 through a synchronous belt 360 passing through the perforation; a protective cover 600 is installed on the outer side of the motor 330, and the perforation is located inside the protective cover 600; the motor is arranged outside the support tube, which can facilitate the installation of the motor, and also facilitate subsequent maintenance and practical application; the protective cover can protect the motor and also block the perforation to prevent the inside of the support tube from being connected with the outside through the perforation, and prevent the exhaust gas from being discharged to the outside through the perforation;

[0030] Furthermore, a control panel is installed on the top of the protective cover, which is used to adjust the speed of the motor and set the position where the baffle swings and stays, thereby changing the frequency, air outlet position and range of the swinging wind, so that the incoming exhaust gas can be fully diffused, allowing the exhaust gas to better contact the filler, reducing blind spots, and improving the overall purification effect; it should be noted that the control panel is a common electronic control component that can be purchased directly on the market and used, and the specific structure will not be repeated.

[0031] Furthermore, second partitions 540 arranged vertically are fixedly provided on both sides of the inner wall of the air duct 500; the contour formed by enclosing between the air duct, the first partition, and the second partition is adapted to the shape of the baffle; both sides of the baffle abut against the wall surfaces of the second partitions and slide, and the top of the baffle abuts against the inner wall top of the air duct and slides; by providing the second partitions, the space inside the air duct can be further defined, and thus the movement of the exhaust gas can be better restricted, so that the exhaust gas is concentrated and discharged from the restricted exhaust port position.
