Description

Technical Field

[0001] The utility model belongs to the technical field of tail gas absorption tower structures, in particular to a reaction tail gas absorption tower. Background Art

[0002] Exhaust gas is the waste gas emitted by motor vehicles or other equipment during operation. Direct exhaust gas emission will cause environmental pollution. Exhaust gas absorption towers are needed to wash and clean the exhaust gas to prevent harmful substances inside the exhaust gas from polluting the air environment. When existing exhaust gas absorption towers treat exhaust gas, it is inconvenient to guide the exhaust gas introduced into the absorption tower, causing the exhaust gas to continue to flow from the same place and unable to fully contact with the granular exhaust gas treatment agent, thereby reducing the exhaust gas treatment effect of the exhaust gas absorption tower.

[0003] In the related art, a search revealed a solution for an exhaust gas absorption tower (Announcement No. CN215311413U), comprising a tower body, an exhaust fan fixedly mounted on the upper surface of the tower body, a drain pipe embedded and fixed at the center of the lower surface of the tower body, a filter device fixedly mounted on the inner side of the tower body between the upper end and the middle part, and an inspection hole provided on the outer side of the tower body near the upper surface and corresponding to the position of the inspection door, so that the filter device can be filled with suitable granular exhaust gas treatment agents according to the composition of the exhaust gas. The filling process is convenient and the operation is simple. The exhaust gas is divided into multiple streams by the exhaust holes on the surface of the hollow sphere, so that the exhaust gas can react more fully with the exhaust gas treatment liquid, making the exhaust gas treatment effect better. However, the absorption tower is not convenient for controlling the direction of the exhaust gas introduction, resulting in the exhaust gas continuing to flow from the same place and unable to fully contact with the granular exhaust gas treatment agent, thereby reducing the exhaust gas treatment effect of the exhaust absorption tower on the exhaust gas.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are:

[0014] The reaction tail gas absorption tower introduces the tail gas to be treated into the conduit, and through the communication effect of the fixed pipe, the tail gas flows into the inner cavity of the rotating plate, and is further sprayed out through a plurality of nozzles, so that the tail gas contacts with the granular tail gas treatment agent, thereby achieving the treatment effect on the tail gas.

At the same time, it is convenient to replace the tail gas treatment agent by opening the box door, thereby improving the treatment effect of the tail gas absorption tower on the tail gas.

DETAILED DESCRIPTION

[0024] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0027] In order to solve the problem that it is difficult to control the direction of the exhaust gas introduced into the reaction exhaust gas absorption tower during use, resulting in uneven contact between the exhaust gas and the exhaust gas treatment agent, thereby reducing the exhaust gas treatment effect, please refer to Figures 1 to 5 The structure of the device body is an absorption tower body 1 for evenly distributing the exhaust gas and a guide component 2 for controlling the direction of exhaust gas introduction. The exhaust gas introduced into the absorption tower body 1 is guided by the set guide component 2, so that the exhaust gas is evenly distributed inside the absorption tower body 1, which facilitates full contact between the exhaust gas and the exhaust gas treatment agent, thereby improving the exhaust gas treatment effect of the exhaust absorption tower. The guide component 2 is arranged on the bottom wall of the absorption tower body 1. The guide component 2 includes a fixed tube 5 and an internal hollow rotating plate 3. The top surface of the rotating plate 3 is equipped with a plurality of nozzles 4 for spraying exhaust gas, which facilitates the spraying of gas through the plurality of nozzles 4.

[0028] The bottom surface of the rotating plate 3 is connected to the fixed tube 5. The side of the fixed tube 5 is interference fit with a fixed bearing 6. The outer ring of the fixed bearing 6 is welded with two connecting plates 7. The fixed bearing 6 is fixed to the rotation position of the fixed tube 5 and provides conditions for the relative rotation of the fixed tube 5 and the two connecting plates 7. The two connecting plates 7 are symmetrically arranged with the fixed bearing 6 as the vertical symmetry axis. The outer peripheral side of the fixed tube 5 is interference fit with a sealed bearing 8. The outer ring of the sealed bearing 8 is embedded and fixedly connected with a conduit 9. The provided sealed bearing 8 provides a sealing effect and provides conditions for the relative rotation of the fixed tube 5 and the conduit 9.

[0029] The outer peripheral side of the conduit 9 passes through the side wall of the absorption tower body 1, thereby facilitating the introduction of exhaust gas into the conduit 9 from the outside of the absorption tower body 1. Under the communication provided by the fixed pipe 5, the exhaust gas flows into the inner cavity of the rotating plate 3, and then the exhaust gas is ejected through a number of nozzles 4. The inner side wall of the absorption tower body 1 is slidingly connected to the two connecting plates 7, and the outer side wall of the absorption tower body 1 is embedded with a rotating rod 10 for rotation. The end face of the rotating rod 10 is fixedly connected to a driving bevel gear, and the driving bevel gear is meshed with a driven bevel gear. The top surface of the driven bevel gear is embedded in the fixed pipe 5 and fixedly connected. The end of the rotating rod 10 away from the driving bevel gear is detachably connected to the output shaft of the rotating motor 11 by a bolt.

[0030] The fixed end of the rotating motor 11 is detachably connected to the absorption tower body 1 by bolts. The rotating motor 11 is provided to provide power so that the output shaft of the rotating motor 11 drives the rotating rod 10 to rotate during the rotation process. Under the meshing action of the active bevel gear and the driven bevel gear, the rotating plate 3 drives the plurality of nozzles 4 to rotate during the transmission process, thereby increasing the range of the exhaust gas sprayed by the nozzle 4, controlling the direction of the exhaust gas introduced into the absorption tower body 1, and realizing uniform distribution of the exhaust gas, thereby facilitating uniform and full contact between the exhaust gas and the granular exhaust gas treatment agent, thereby improving the exhaust gas treatment effect of the exhaust absorption tower.

[0031] The top surface of the absorption tower body 1 is connected to the absorption box 13, which facilitates the exhaust gas inside the absorption tower body 1 to flow into the absorption box 13. The inner wall of the absorption box 13 is slidably connected to the filter frame 18, and the inner wall of the filter frame 18 is fixedly connected to the filter screen 19 for storing granular exhaust gas treatment agent. The filter frame 18 is provided to provide support for the filter screen 19, and the filter screen 19 is provided to provide shielding and support for the exhaust gas treatment agent, which facilitates the contact between the exhaust gas and the exhaust gas treatment agent to achieve the treatment of the exhaust gas. L-shaped limit plates 17 are welded at both ends of the bottom of the filter frame 18, and the bottom surface of the limit plate 17 is detachably connected to the movable end of the electric telescopic rod 16 by bolts.

[0032] The electric telescopic rod 16 is provided to provide power, and under the connection provided by the limit plate 17, the filter frame 18 and the filter screen 19 are longitudinally reciprocatingly moved during the transmission process, thereby providing a vibration and bumping effect on the exhaust gas treatment agent on the top surface of the filter screen 19, preventing the granular exhaust gas treatment agent from abutting each other and being inconvenient to contact the exhaust gas, thereby improving the exhaust gas treatment effect of the exhaust gas absorption tower. The fixed end of the electric telescopic rod 16 is detachably connected to the fixing plate 15 by bolts, and the fixed plate 15 is provided to provide support and fixing for the electric telescopic rod 16. The centrifugal side of the two fixing plates 15 is welded to the absorption box 13, and the top and side surfaces of the absorption box 13 are respectively installed with an exhaust port 14 and a box door 12, which is convenient for replacing the exhaust gas treatment agent inside the absorption box 13 by opening the box door 12.

[0033] The rotating motor 11 and the electric telescopic rod 16 are both prior art. Their working principles, sizes and models are irrelevant to the functions of the present application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0034] How it works

[0035] When using the reaction tail gas absorption tower, the user introduces the tail gas to be treated into the conduit 9, so that the tail gas flows into the inner cavity of the rotating plate 3 through the fixed pipe 5 and is then sprayed out through the plurality of nozzles 4. The rotating motor 11 is started, and the output shaft of the rotating motor 11 drives the rotating rod 10 to rotate during the rotation process. Under the meshing action of the driving bevel gear and the driven bevel gear, the rotating plate 3 drives the plurality of nozzles 4 to rotate during the transmission process. The provided fixed bearing 6 and the two connecting plates 7 provide support for the fixed pipe 5. The provided sealed bearing 8 provides conditions for the relative rotation of the fixed pipe 5 and the conduit 9, thereby achieving uniform distribution of the tail gas.

[0036] The exhaust gas inside the absorption tower body 1 flows into the absorption box 13, so that the exhaust gas contacts the granular exhaust gas treatment agent on the top of the filter screen 19, thereby achieving the treatment effect on the exhaust gas. The two electric telescopic rods 16 are started, and the movable end of the electric telescopic rod 16 moves. Under the connection provided by the limit plate 17, the filter frame 18 and the filter screen 19 are moved back and forth longitudinally during the transmission process, thereby providing a vibration and bumping effect to the exhaust gas treatment agent on the top surface of the filter screen 19, thereby preventing the exhaust gas treatment agent from contacting each other and being inconvenient to contact with the exhaust gas.
