Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, and in particular to a large particulate matter separation device for waste gas treatment. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life. Chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries, in particular, emit waste gases with strong odors that severely pollute the environment and affect human health. Waste gases are diverse, with complex physical and chemical properties and varying degrees of toxicity. Waste gases emitted from fuel combustion contain sulfur dioxide, nitrogen oxides (NOx), hydrocarbons, etc. Due to differences in raw materials and processes used in industrial production, various harmful gases and solid wastes are emitted, containing various components such as heavy metals, salts, and radioactive substances.

[0003] Currently, in order to reduce the pollution of the environment by exhaust gas, factories have set up special treatment devices for exhaust gas. Existing exhaust gas treatment large particulate matter separation devices mainly use filter screens to filter and purify particulate impurities in exhaust gas. However, over time, more and more particles are trapped, which leads to the filter pores becoming smaller and smaller, eventually causing blockage. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems mentioned above, and to propose a large particulate matter separation device for waste gas treatment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a large particulate matter separation device for waste gas treatment, comprising a separation box, four support rods fixedly installed on the bottom surface of the separation box, a water inlet pipe and multiple hollow pipes fixedly installed between the inner walls of both sides of the separation box, multiple nozzles fixedly installed on the outer surface of the water inlet pipe and the multiple hollow pipes, connecting pipes fixedly installed between the water inlet pipe and one of the hollow pipes and between two adjacent hollow pipes, an exhaust pipe fixedly installed on the top surface of the separation box, and auxiliary devices provided on the inner walls of both sides of the separation box, each auxiliary device comprising two sliding grooves, a filter screen slidably connected between the two sliding grooves in the vertical direction, and two first springs fixedly installed between the inner bottom surface of the two sliding grooves and the filter screen. The first springs restrict the position of the filter screen inside the sliding grooves, and the filter screen filters small particulate impurities in the waste gas. The auxiliary device also includes a striking component, which strikes the filter screen between gaps.

[0006] Preferably, the striking component is fixed to a mounting frame on the inner wall of the separation chamber. A connecting rod is vertically slidably connected to the bottom of the mounting frame, and a striking ball is fixedly installed at the end of the connecting rod away from the mounting frame. The striking ball is designed to shake off fine impurities from the surface of the filter screen.

[0007] Preferably, a motor is fixedly installed on the outer wall of the separation box, and a cam is fixedly installed on the output shaft of the motor. The bottom of the cam contacts the connecting rod, and a return spring is installed between the striking ball and the mounting frame.

[0008] Preferably, the bottom surface of the separation box is provided with a limiting device, which includes a mounting groove. The mounting groove is formed on the bottom surface of the separation box, and a mounting plate is movably installed inside the mounting groove. A base plate is fixedly installed on the side of the mounting plate, and a drain pipe and an air inlet pipe are fixedly installed on the bottom surface of the base plate. A valve is fixedly installed on the outer wall surface of the drain pipe. The mounting plate and the mounting groove serve to initially limit the position of the base plate and the separation box.

[0009] Preferably, the bottom surface of the separation box has a strip-shaped groove, and a displacement plate is slidably connected inside the strip-shaped groove. A limit rod is fixedly installed on the surface of the displacement plate, and a limit hole is opened on the side of the mounting plate. The limit rod and the limit hole effectively limit the mounting plate inside the mounting groove.

[0010] Preferably, a second spring is fixedly installed between the end of the displacement plate away from the limiting rod and the inner wall of one side of the strip groove, and a pull ring is fixedly installed on the surface of the end of the displacement plate away from the limiting rod. The second spring serves to limit the position of the displacement plate inside the strip groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting an auxiliary device, when it is necessary to use the device to separate large particulate impurities in the exhaust gas, the exhaust gas outlet end and the inlet pipe are first connected. As the exhaust gas continues to move upward, it will be filtered by the filter screen, thereby separating the fine particles in the exhaust gas from the exhaust gas. Finally, the exhaust gas filtered by the filter screen is discharged from the inside of the separation box through the exhaust pipe, thus completing the entire waste gas impurity separation operation. When the filter screen holes are blocked, resulting in low throughput, the motor is started. The motor starts and drives the cam to rotate. The rotation of the cam drives the connecting rod to move up and down reciprocally. The support rod moves downward and drives the striking ball to move downward. The striking ball moves downward and strikes the filter screen. The filter screen is subjected to force and squeezes the first spring to vibrate. During the vibration process of the filter screen, the impurities stuck inside the mesh are shaken out to the bottom plate of the separation box. Although the above operation cannot clean up the impurities separated by the filter screen, it can ensure the permeability of the filter screen (that is, the filter screen has high permeability for a certain period of time after the filter screen is struck).

[0013] 2. In this utility model, the exhaust outlet and the intake pipe are separated (either removed or closed), and then the external water source and the water inlet pipe are connected. Water flows from the water inlet pipe into the interior of the connecting pipe, and then from the interior of the connecting pipe into the interior of the hollow pipe, and finally sprays out from the nozzle. The sprayed water is used to backwash the filter screen. The filter screen is cleaned by the tapping of the auxiliary device. When the valve is opened, the water inside the separation box can flow out from the inside of the separation box through the drain pipe (the water mixed with the debris blocked by the filter screen flows out).

[0014] 3. In this utility model, by setting a limiting device, when it is necessary to clean the impurities on the surface of the bottom plate, after all the water has flowed out, the pull ring is pulled. The pull ring moves and drives the displacement plate to move inside the strip groove. The movement of the displacement plate inside the strip groove will squeeze the second spring, causing the second spring to be compressed. At the same time, the movement of the displacement plate will also drive the limiting rod to move. The movement of the limiting rod will cause it to move out of the limiting hole. The separation of the limiting rod and the limiting hole will cause the mounting plate to lose its limiting position inside the mounting groove. The loss of the limiting position inside the mounting groove will cause the bottom plate and the separation box to lose their limiting position. At this time, the bottom plate can be removed from the separation box, completing the disassembly operation of the bottom plate and cleaning the impurities remaining on the surface of the bottom plate. Through the cooperation of the above structure, the bottom plate and the separation box can be disassembled, which facilitates the cleaning of the impurities remaining on the surface of the bottom plate and prevents impurities from remaining on the surface of the bottom plate after the water inside the separation box has been drained.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figure 1-6This utility model provides a technical solution: a large particulate matter separation device for waste gas treatment, including a separation box 1, four support rods 2 fixedly installed on the bottom surface of the separation box 1, a water inlet pipe 5 and a plurality of hollow pipes 7 fixedly installed between the inner walls of both sides of the separation box 1, a plurality of nozzles 6 fixedly installed on the outer surface of the water inlet pipe 5 and the plurality of hollow pipes 7, a connecting pipe 8 fixedly installed between the water inlet pipe 5 and one of the hollow pipes 7 and between two adjacent hollow pipes 7, and an exhaust pipe 9 fixedly installed on the top surface of the separation box 1.

[0026] The specific settings and functions of its auxiliary device 3 and limiting device 4 will be explained below.

[0027] In this embodiment: Auxiliary devices 3 are provided on both inner wall surfaces of the separation box 1. The auxiliary devices 3 include two slide grooves 301, and a filter screen 302 is slidably connected between the two slide grooves 301 in the vertical direction. Two first springs 303 are fixedly installed between the inner bottom surface of the two slide grooves 301 and the filter screen 302. The auxiliary devices 3 also include a striking component, which strikes the filter screen 302 through the gap.

[0028] In this embodiment, the first spring 303 restricts the position of the filter screen 302 inside the slide groove 301, and the filter screen 302 filters small particulate impurities in the exhaust gas.

[0029] Specifically, the striking component is fixed to the mounting frame 306 on the inner wall of the separation box 1. A connecting rod 307 is vertically slidably connected to the bottom of the mounting frame 306. A striking ball 308 is fixedly installed at the end of the connecting rod 307 away from the mounting frame 306.

[0030] In this embodiment, the striking ball 308 is designed to shake off small impurities from the surface of the filter screen 302.

[0031] Specifically, a motor 309 is fixedly installed on the outer wall of the separation box 1, and a cam 310 is fixedly installed on the output shaft of the motor 309. The bottom of the cam 310 contacts the connecting rod 307, and a return spring 304 is installed between the striking ball 308 and the mounting frame 306.

[0032] Specifically, a strip groove 404 is provided on the bottom surface of the separation box 1, and a displacement plate 405 is slidably connected inside the strip groove 404. A limit rod 406 is fixedly installed on the surface of the displacement plate 405, and a limit hole 407 is provided on the side of the mounting plate 402.

[0033] In this embodiment, the limiting rod 406 and the limiting hole 407 are designed to limit the mounting plate 402 inside the mounting groove 401.

[0034] Specifically, a second spring 408 is fixedly installed between the end of the displacement plate 405 away from the limiting rod 406 and the inner wall of one side of the strip groove 404, and a pull ring 409 is fixedly installed on the surface of the end of the displacement plate 405 away from the limiting rod 406.

[0035] In this embodiment, the second spring 408 serves to limit the position of the displacement plate 405 inside the strip groove 404.

[0036] Working principle: When using this device to separate large particulate matter from exhaust gas, first connect the exhaust gas outlet to the inlet pipe 412. As the exhaust gas continues to move upward, it will be filtered by the filter screen 302, thus separating the fine particles from the exhaust gas. Finally, the exhaust gas filtered by the filter screen 302 is discharged from the inside of the separation box 1 through the exhaust pipe 9, thus completing the entire waste gas separation operation. When the filter screen 302 becomes clogged, causing low throughput, the motor 309 is started. The motor 309 drives the cam 305 to rotate, and the rotation of the cam 305 drives the connecting rod 307 to move up and down reciprocally. The support rod 2 moves downward, causing the striking ball 308 to move downward. The striking ball 308 moves downwards to strike the filter screen 302. The force on the filter screen 302 compresses the first spring 303, causing it to vibrate. This vibration dislodges debris trapped inside the mesh onto the bottom plate 403 of the separation box 1. While this operation cannot remove the debris separated by the filter screen 302, it ensures the permeability of the filter screen 302 (i.e., the filter screen 302 maintains high permeability for a certain period after being struck). The exhaust outlet and inlet pipe 412 are then separated (either by removal or closure). The external water source is then reconnected to the water inlet pipe 5. Water flows from the water inlet pipe 5 into the connecting pipe 8, then from the connecting pipe 8 into the hollow pipe 7, and finally exits from the nozzle. 6. The sprayed water is used to backwash the filter screen 302. Combined with the tapping action of the auxiliary device 3, the filter screen 302 is cleaned. Opening valve 411 allows water inside the separation chamber 1 to flow out through drain pipe 410 (water mixed with debris blocked by the filter screen 302 flows out). When cleaning impurities from the surface of the bottom plate 403 is required, after all the water has flowed out, pull ring 409 is pulled. The movement of pull ring 409 causes displacement plate 405 to move inside the strip groove 404. The movement of displacement plate 405 inside the strip groove 404 compresses the second spring 408, causing it to be compressed. Simultaneously, the movement of displacement plate 405 also moves limit rod 406. 6. The movement causes it to move out of the limiting hole 407. The separation of the limiting rod 406 and the limiting hole 407 causes the mounting plate 402 to lose its limiting position inside the mounting groove 401. The loss of the limiting position of the mounting plate 402 inside the mounting groove 401 causes the bottom plate 403 and the separation box 1 to lose their limiting position. At this time, the bottom plate 403 can be removed from the separation box 1, completing the disassembly operation of the bottom plate 403. The impurities remaining on the surface of the bottom plate 403 are cleaned. Through the cooperation of the above structure, the bottom plate 403 and the separation box 1 can be disassembled, which facilitates the cleaning of the impurities remaining on the surface of the bottom plate 403 and prevents impurities from remaining on the surface of the bottom plate 403 after the water inside the separation box 1 has been drained.
