Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, specifically to a multi-stage purification device for industrial waste gas. Background Technology

[0002] In today's era of rapid industrialization, various industrial production activities are flourishing. However, industrial production inevitably generates a large amount of industrial waste gas. This waste gas has a complex composition, often containing large particulate impurities, fine dust, harmful particulate pollutants, odors, and organic pollutants, among other harmful substances. If it is directly discharged into the atmosphere without effective treatment, it will not only severely pollute air quality, causing environmental problems such as smog and acid rain, but also pose a great threat to human health, leading to respiratory and cardiovascular diseases. Furthermore, it will adversely affect the growth of plants and animals in the ecological environment.

[0003] Existing industrial waste gas has a complex composition, containing various harmful substances such as particulate matter, harmful gases, and organic pollutants. A single purification method is difficult to meet the stringent environmental emission standards. Furthermore, during the intake operation, the traditional intake structure design is relatively fixed and cannot adapt to the differences in the location, direction, and flow rate of waste gas emission outlets in different industrial scenarios. When the relative position of the waste gas emission source and the purification device changes, traditional devices often need to rearrange the pipeline or adjust the equipment installation position, which is complicated and costly, greatly limiting the versatility and adaptability of the device. Therefore, this utility model provides a multi-stage purification device for industrial waste gas. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-stage purification device for industrial waste gas. It solves the problems of complex industrial waste gas composition, which includes particulate matter, harmful gases, organic pollutants and other harmful substances. A single purification method is difficult to meet strict environmental emission standards. In addition, during the intake operation, the traditional intake structure design is relatively fixed and cannot adapt to the differences in the position, direction and flow of waste gas emission outlets in different industrial scenarios. When the relative position of the waste gas emission source and the purification device changes, traditional devices often need to rearrange the pipeline or adjust the equipment installation position, which is complicated and costly, and greatly limits the versatility and adaptability of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage purification device for industrial waste gas, comprising a purification body, wherein the purification body is provided with an installation mechanism for multi-stage purification of industrial waste gas, the installation mechanism comprising:

[0006] The air intake assembly includes a guide shell fixed at one end of the purification body, a bellows at one end of the guide shell, an air inlet at one end of the bellows, a mounting plate fixed on the upper surface of the guide shell, a support shaft connected to the upper surface of the mounting plate via a locking assembly, a mounting bracket connected to the upper end of the support shaft via a rotating assembly, an adjusting plate fixed on the outer wall of the support shaft, and the mounting bracket being fixedly connected to the air inlet.

A high and low voltage electric field power supply body is provided inside the purification body on the right side of the Z-shaped filter support. An activated carbon mesh frame is provided inside the purification body on the right side of the high and low voltage electric field power supply body.

[0008] Preferably, the locking assembly includes threaded holes evenly spaced on the upper surface of the mounting plate, the support shaft is rotatably connected to the upper surface of the mounting plate, and a locking bolt threaded to the threaded holes is provided on one side of the adjusting plate.

[0009] Preferably, the rotating assembly includes a fixed plate fixed to the top of a support shaft, an adjusting bracket rotatably connected to one end of the fixed plate via a rotating shaft, the adjusting bracket having an L-shaped structure, a mounting bracket located at the lower end of the adjusting bracket and rotatably connected via a rotating shaft, a horizontal plate fixed to the other end of the adjusting plate, an electric push rod rotatably connected to the upper surface of the horizontal plate via a rotating shaft, and the telescopic end of the electric push rod rotatably connected to the lower surface of the adjusting bracket via a rotating shaft.

[0013] This utility model provides a multi-stage purification device for industrial waste gas, which has the following advantages compared with the prior art:

[0014] Firstly, this utility model uses an electric push rod to drive the adjustment bracket and mounting bracket to rotate, which can precisely adjust the angle of the air inlet. This allows it to better adapt to different exhaust gas emission conditions and the installation position of the purification unit. In conjunction with the corrugated pipe, the air inlet can be easily connected to various exhaust gas emission sources without being strictly limited by position and direction. This improves the versatility and adaptability of the device, enabling it to meet the exhaust gas introduction needs under different working conditions without the need for frequent adjustments to the position and height of the entire device.

[0015] Secondly, the design of this utility model, through the sliding component, allows the Z-shaped filter support to easily slide in or out from the outside of the purification body, facilitating the installation, replacement, and maintenance of the Z-shaped filter, greatly shortening maintenance time and improving work efficiency. The filter installed on the Z-shaped filter support initially intercepts and filters large particulate impurities in the exhaust gas. After initial filtration, the exhaust gas continues to flow to the right and enters the high and low voltage electric field power supply body area. The high and low voltage electric field power supply body generates an electric field, using electric field force to adsorb and remove fine dust and some harmful particulate pollutants in the exhaust gas. The exhaust gas after electric field treatment then enters the activated carbon mesh frame area. The activated carbon mesh frame is located inside the installation shell and can slide. The exhaust gas removes odors, organic pollutants, etc. through the adsorption of activated carbon. Finally, the purified gas is discharged from the exhaust body. Through the arrangement of the high and low voltage electric field power supply body, activated carbon mesh frame, and Z-shaped filter support, multi-stage purification of industrial exhaust gas is achieved, which can effectively remove different pollutants in the exhaust gas and improve purification efficiency and purification quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a multi-stage purification device for industrial waste gas, including a purification body 1, on which an installation mechanism for multi-stage purification of industrial waste gas is provided, the installation mechanism including:

[0023] The air intake assembly includes a guide shell 2 fixed at one end of the purification body 1, a bellows 201 provided at one end of the guide shell 2, an air inlet 202 fixed at one end of the bellows 201, a mounting plate 204 fixed at the upper end of the guide shell 2, a support shaft 205 connected by a locking assembly at the upper end of the mounting plate 204, a mounting bracket 203 connected by a rotating assembly at the upper end of the support shaft 205, an adjusting plate 3 fixed at the outer wall of the support shaft 205, and the mounting bracket 203 and the air inlet 202 being movably sleeved together.

[0024] The purification component includes a support slide rail 4 fixedly connected inside the purification body 1. A Z-shaped filter support 402 connected by a sliding component is provided inside the support slide rail 4. A high and low voltage electric field power supply body 5 is provided inside the purification body 1 on the right side of the Z-shaped filter support 402. An activated carbon mesh frame 503 is provided inside the purification body 1 on the right side of the high and low voltage electric field power supply body 5.

[0025] In a preferred embodiment, the locking assembly includes threaded holes 302 evenly spaced on the upper surface of the mounting plate 204, a support shaft 205 rotatably connected to the upper surface of the mounting plate 204, and a locking bolt 301 threadedly connected to the threaded holes 302 on one side of the adjusting plate 3. The rotating assembly includes a fixing plate 206 fixed to the top of the support shaft 205, and an adjusting bracket 207 rotatably connected to one end of the fixing plate 206 via a rotating shaft. The adjusting bracket 207 has an L-shaped structure, and the mounting bracket 203 is located at the lower end of the adjusting bracket 207 via a rotating shaft. The rotating shaft is connected to the other end of the adjusting plate 3, and a horizontal plate 303 is fixed thereon. The upper end of the horizontal plate 303 is provided with an electric push rod 304 that is rotatably connected by the rotating shaft. The telescopic end of the electric push rod 304 is rotatably connected to the lower end of the adjusting bracket 207 by the rotating shaft. Industrial waste gas enters from the air inlet 202, passes through the corrugated pipe 201 and enters the guide shell 2, and then enters the purification body 1 for subsequent purification treatment. The corrugated pipe 201 can play a certain buffering and connecting role, which facilitates connection with waste gas emission sources in different positions or directions.

[0026] When the angle of the air inlet 202 needs to be adjusted to adapt to different exhaust gas emission conditions or the installation position of the purification unit 1, the electric push rod 304 is activated. The telescopic end of the electric push rod 304 extends and retracts. Since the telescopic end of the electric push rod 304 is rotatably connected to the lower end face of the adjusting bracket 207 via a rotating shaft, and the adjusting bracket 207 is rotatably connected to one end of the fixed plate 206 via a rotating shaft, and the mounting bracket 203 is rotatably connected to the lower end of the adjusting bracket 207 via a rotating shaft, the telescopic movement of the electric push rod 304 will drive the adjusting bracket 207 to rotate around the rotating shaft at the fixed plate 206, thereby driving the mounting bracket 203 and the air inlet... 202 rotates together, and at the same time, the support shaft 205 rotates on the mounting plate 204, and the adjusting plate 3 rotates accordingly. When the air inlet 202 is adjusted to a suitable angle, the locking bolt 301 on one side of the adjusting plate 3 is screwed into the threaded holes 302 evenly opened on the upper end face of the mounting plate 204 to fix the adjusting plate 3 and the support shaft 205, thereby fixing the angle of the air inlet 202 at the current position, realizing the omnidirectional adjustment of the air inlet 202 in the up and down and left and right directions, and the air inlet 202 can move with the mounting bracket 203, thereby allowing the air inlet 202 to move horizontally and connect with the exhaust gas emission source pipeline.

[0027] The electric push rod 304 drives the adjusting bracket 207 and the mounting bracket 203 to rotate, which can precisely adjust the angle of the air inlet 202. This allows it to better adapt to different exhaust gas emission conditions and the installation position of the purification unit 1. The corrugated pipe 201, in conjunction with the setting of the air inlet 202, enables it to be easily connected to various exhaust gas emission sources without being strictly limited by position and direction. This improves the versatility and adaptability of the device, allowing it to meet the exhaust gas introduction requirements under different working conditions.

[0028] In a preferred embodiment, a mounting shell 501 is fixed to the right end of the purification body 1, the activated carbon mesh frame 503 is slidably connected inside the mounting shell 501, and an air outlet body 502 is provided on the front end face of the mounting shell 501.

[0029] In a preferred embodiment, the sliding assembly includes a fixed bracket 401 slidably connected inside the supporting slide rail 4. A Z-shaped filter holder 402 is fixedly connected inside the fixed bracket 401. A locking plate 403 is fixed to one end of the fixed bracket 401 extending to the outside of the purification body 1. Limiting brackets 404 are provided on both sides of the locking plate 403, and bolts are installed inside the limiting brackets 404 to connect with the purification body 1. The Z-shaped filter holder 402 is fixed inside the fixed bracket 401, which is slidably connected inside the supporting slide rail 4. When it is necessary to install or replace the Z-shaped filter, the fixed bracket 401, together with the Z-shaped filter holder 402, can be slid from the outside of the purification body 1 into the supporting slide rail 4 to install the Z-shaped filter. When it is necessary to replace or maintain the Z-type filter, the fixed bracket 401 can also be slid out from the support slide rail 4. The fixed bracket 401 extends to the outer end of the purification body 1 and is fixed with a locking plate 403. Limit brackets 404 are provided on both sides of the locking plate 403. When the Z-type filter bracket 402 and the fixed bracket 401 slide to the appropriate position, the limit brackets 404 are connected to the purification body 1 by bolts, thereby fixing the locking plate 403 and the fixed bracket 401 and preventing the Z-type filter bracket 402 from sliding during operation.

[0030] The sliding component design allows the Z-type filter holder 402 to easily slide in or out from the outside of the purification body 1, facilitating the installation, replacement, and maintenance of the Z-type filter, greatly shortening maintenance time and improving work efficiency. The filter installed on the Z-type filter holder 402 performs preliminary interception and filtration of large particulate impurities in the exhaust gas. After preliminary filtration, the exhaust gas continues to flow to the right and enters the high and low voltage electric field power supply body 5 area. The high and low voltage electric field power supply body 5 generates an electric field, which is used to adsorb and remove fine dust and some harmful particulate pollutants in the exhaust gas. After being treated by the electric field, the exhaust gas enters the activated carbon mesh frame 503 area. The activated carbon mesh frame 503 is located inside the mounting shell 501 and is slidable. The exhaust gas removes odors, organic pollutants, etc. through the adsorption of activated carbon. Finally, the purified gas is discharged from the exhaust body 502.

[0031] In this process, the exhaust gas enters the main body 5 of the high and low voltage electric field power supply. Under the action of the high and low voltage electric field, the tiny particles and harmful gas molecules in the exhaust gas are ionized, adsorbed and collected, achieving further purification treatment.

[0032] After being purified by the high and low voltage electric fields, the exhaust gas continues to flow to the right and enters the activated carbon mesh frame 503 area. The activated carbon in the mesh frame 503 has a rich porous structure and a large specific surface area, which can adsorb harmful substances such as odors and organic matter in the exhaust gas, thus deeply purifying the exhaust gas. Finally, the purified exhaust gas is discharged from the exhaust body 502 on the front end of the housing 501.

[0033] The multi-stage purification of industrial waste gas is achieved through the arrangement of the high and low voltage electric field power supply body 5, the activated carbon mesh frame 503, and the Z-shaped filter support 402. This effectively removes different pollutants from the waste gas, improves purification efficiency and quality, and ensures that the emitted waste gas meets environmental protection requirements. The activated carbon mesh frame 503 can perform deep adsorption treatment on the waste gas after purification by the high and low voltage electric fields, removing odors and organic matter that are difficult to purify through the electric field, further improving the emission quality of the waste gas. The high and low voltage electric field power supply body 5 and the activated carbon mesh frame 503 are arranged sequentially inside the purification body 1, with a reasonable structural layout that makes full use of the space of the purification body 1, improves purification efficiency, and facilitates the maintenance and management of each purification component.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, industrial waste gas enters through inlet 202, is buffered and connected by bellows 201, then enters guide housing 2, and finally enters purification body 1 for further purification. When the angle of inlet 202 needs to be adjusted, the electric push rod 304 is activated, its telescopic end extends and retracts, driving the adjusting bracket 207 to rotate around the rotating shaft at the fixed plate 206, which in turn drives the mounting bracket 203 and inlet 202 to rotate. The support shaft 205 rotates on the mounting plate 204, and the adjusting plate 3 rotates accordingly. After adjusting to the appropriate angle, the locking bolt 301 on one side of the adjusting plate 3 is screwed into the threaded hole 302 of the mounting plate 204 to fix the angle of inlet 202. The waste gas entering the purification body 1 is first filtered by the Z-shaped filter support 40. The filter screen on the 2nd part intercepts large particulate impurities. The Z-shaped filter screen bracket 402 is slidably connected to the support slide rail 4 via the fixed bracket 401. When installing or replacing the filter screen, the fixed bracket 401 together with the Z-shaped filter screen bracket 402 is slid in or out. After being in place, it is fixed by the bolts inside the limiting bracket 404. The exhaust gas after preliminary filtration enters the high and low voltage electric field power supply body 5 area. Under the action of electric field force, small particles, harmful gas molecules, etc. are ionized, adsorbed and collected. The exhaust gas after electric field treatment enters the activated carbon mesh frame 503 area. The activated carbon uses its rich pore structure and large specific surface area to adsorb odors, organic matter and other harmful substances. Finally, the purified gas is discharged from the exhaust body 502 on the front end of the mounting shell 501.
