Description

Technical Field

[0001] This utility model relates to the field of gas emission filtration technology, and in particular to a gas emission filtration device for environmental monitoring. Background Technology

[0002] Environmental monitoring gas emission filtration devices are specialized equipment used to monitor, control, and purify harmful gas components in industrial or domestic waste gas. They aim to reduce pollutant emissions, protect the environment, and meet environmental regulations. These devices typically combine gas detection technology and filtration and purification technology to ensure that emitted gases meet environmental standards.

[0003] Currently, environmental monitoring gas emission filtration devices require initial filtration of particulate matter or dust in the gas before chemical filtration based on the gas composition to meet emission standards. However, during dust filtration, large particles or dust may become stuck on one side of the filter plate. Over time, this accumulation can clog the filter holes, affecting filtration efficiency. Furthermore, prolonged dust adhesion can significantly reduce the lifespan of the filter plate. During chemical filtration, some gases may react slowly with chemical agents, and the resulting solids may reduce the reaction volume, causing some gases to be emitted before the reaction is complete, thus polluting the environment. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An environmental monitoring gas emission filtration device, comprising:

[0006] The discharge pipe has a filter plate slidably installed on its side wall, a reaction chamber slidably connected to its side wall, and an induced draft fan fixedly installed inside its side.

[0007] A cleaning structure is installed on the discharge pipe. The cleaning structure includes a control motor fixedly installed on the upper side of the discharge pipe. A reciprocating screw is rotatably connected to the inner side of the discharge pipe. A bevel gear is fixedly sleeved on the outer side of both the reciprocating screw and the output end of the control motor, and the two bevel gears mesh with each other. Two fixed rods are fixedly connected to the side wall of the discharge pipe. A cleaning plate is slidably connected to the outer side of the two fixed rods. A reciprocating block is rotatably connected to the side wall of the cleaning plate.

[0008] Preferably, the discharge pipe is equipped with a stirring structure, which includes a rotating shaft rotatably connected to the side wall of the discharge pipe. The rotating shaft is connected to a reciprocating screw via a pulley assembly. A spur gear is fixedly sleeved on the outside of the rotating shaft. Three connecting plates are rotatably connected to the outside of the rotating shaft. Each of the three connecting plates has a rotating shaft rotatably connected to its side wall. A spur gear is fixedly sleeved on the outside of each of the three rotating shafts, and the spur gear meshes with each of the three spur gears. A gear ring is fixedly connected to the side wall of the discharge pipe, and the gear ring meshes with each of the three spur gears. Stirring blades are fixedly connected to the outside of the three rotating shafts.

[0009] Preferably, a dust collection box is slidably connected to the lower side of the discharge pipe.

[0010] Preferably, multiple sets of soft brushes are fixedly installed on the side wall of the cleaning plate.

[0011] Preferably, four stops are rotatably connected to the lower side of the discharge pipe.

[0012] Preferably, a handle is fixedly installed on the side wall of the dust collection box.

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

[0014] 1. In this utility model, the cleaning structure enables the surface of the filter plate to be cleaned during the gas filtration process, avoiding the accumulation of dust that could clog the filter holes in the filter plate and thus affect the filtration efficiency. Furthermore, cleaning the filter plate can reduce the erosion of the filter plate by dust, thereby greatly increasing the service life of the filter plate.

[0015] 2. In this utility model, the rotating structure allows the chemical agent to be stirred. The shear force generated by stirring breaks the gas into smaller bubbles, thereby increasing the gas-liquid interface area and greatly increasing the chemical reaction rate. It can also prevent the formation of a solid film that would prevent the subsequent gas from directly contacting the chemical agent and thus prevent the reaction from occurring, ensuring that the gas has reacted with the chemical agent before being discharged.

[0022] Reference Figures 1-5 An environmental monitoring gas emission filtration device, comprising:

[0023] The discharge pipe 1 has a filter plate 2 slidably installed on its side wall. A dust collection box 19 is slidably connected to the lower side of the discharge pipe 1. A handle is fixedly installed on the side wall of the dust collection box 19. By pulling the handle, the dust collection box 19 can be pulled out to directly process the dust filtered by the filter plate 2. A reaction box 3 is slidably connected to the side wall of the discharge pipe 1. The reaction box 3 has good corrosion resistance and can store chemical reagents. Four stops 20 are rotatably connected to the lower side of the discharge pipe 1. Rotating the four stops 20 can fix or remove the reaction box 3, which facilitates the replacement of chemical reagents in the reaction box 3. An induced draft fan 4 is fixedly installed inside the discharge pipe 1. The induced draft fan 4 is a key device used in the industrial field to guide the flow of gas. It is mainly used for exhaust, air supply or maintaining system pressure balance. The induced draft fan 4 is installed at the tail end of the discharge pipe 1. It causes the gas in the discharge pipe 1 to be transported backward by exhaust. The induced draft fan 4 is externally powered. This is existing technology and will not be described in detail.

[0024] A cleaning structure is installed on the discharge pipe 1. The cleaning structure includes a control motor 5 fixedly installed on the upper side of the discharge pipe 1. A reciprocating screw 6 is rotatably connected to the inner side of the discharge pipe 1. A bevel gear 7 is fixedly sleeved on the outer side of both the output end of the reciprocating screw 6 and the control motor 5, and the two bevel gears 7 mesh with each other. Two fixed rods 8 are fixedly connected to the side wall of the discharge pipe 1. A cleaning plate 9 is slidably connected to the outer side of the two fixed rods 8. Multiple sets of soft brushes are fixedly installed on the side wall of the cleaning plate 9. A reciprocating block 10 is rotatably connected to the side wall of the cleaning plate 9. The reciprocating block 10 can slide along the reciprocating groove on the outer side of the reciprocating screw 6, thereby causing the cleaning plate 9 to reciprocate.

[0025] A stirring structure is installed on the discharge pipe 1. The stirring structure includes a rotating shaft 11 rotatably connected to the side wall of the discharge pipe 1. The rotating shaft 11 is connected to the reciprocating screw 6 via a pulley assembly 12. The pulley assembly 12 consists of two pulleys and a belt. The power of the reciprocating screw 6 is transmitted to the rotating shaft 11 through the pulley assembly 12. A spur gear 13 is fixedly sleeved on the outside of the rotating shaft 11. Three connecting plates 14 are rotatably connected to the outside of the rotating shaft 11. The side walls of the three connecting plates 14 are all rotatably connected to rotating shafts. 15. Spur gears 16 are fixedly sleeved on the outer side of each of the three rotating shafts 15, and spur gears 13 mesh with the three spur gears 16 respectively. A gear ring 17 is fixedly connected to the side wall of the discharge pipe 1, and the gear ring 17 meshes with the three spur gears 16 respectively. Spur gears 13, three spur gears 16 and gear ring 17 form a planetary gear, so that the three spur gears 16 can drive the rotating shafts 15 to rotate while making circular motion with spur gears 13 as the center. Stirring blades 18 are fixedly connected to the outer side of the three rotating shafts 15.

[0026] In this invention, firstly, the industrial waste gas is discharged into the discharge pipe 1. The exhaust gas is then drawn backward by the suction of the induced draft fan 4. During this process, the waste gas first passes through the filter plate 2, where larger particles such as dust are filtered out. Then, the control motor 5 is activated, which drives the reciprocating screw 6 via two bevel gears 7. The rotation of the reciprocating screw 6 causes the cleaning plate 9 to slide up and down on the outside of the two fixed rods 8 via the reciprocating block 10, thus making the cleaning plate 9 reciprocate. During this reciprocating motion, the cleaning plate 9 cleans the surface of the filter plate 2 using multiple sets of soft brushes on its sidewalls, preventing dust accumulation that could clog the filter holes and affect filtration efficiency. Furthermore, cleaning the filter plate 2 reduces dust erosion. This greatly increases the service life of the filter plate 2. During the continued transmission of gas, the reciprocating screw 6 also drives the rotating shaft 11 to rotate through the pulley assembly 12. The rotating shaft 11 drives the first spur gear 13 to rotate, and the rotation of the first spur gear 13 drives the three second spur gears 16 to rotate. During the rotation of the second spur gears 16, they can also make circular motion by meshing with the gear ring 17. The first spur gear 13, the three second spur gears 16 and the gear ring 17 form a planetary gear, which enables the stirring blade 18 to make circular motion while rotating. The shearing force brought by stirring breaks the gas into smaller bubbles, thereby increasing the gas-liquid interface area, greatly increasing the chemical reaction rate, and preventing the formation of solid films that would prevent the reaction from occurring. This ensures that the gas has reacted with the chemical reagent before being discharged.
