Description

Technical Field

[0001] This invention relates to the field of gas pollution treatment technology, and in particular to a real-time gas pollution treatment device. Background Technology

[0002] Traditional bag filters typically employ a fixed filtration structure, where particulate matter is trapped on the surface of the filter bag as polluted gas passes through. However, with prolonged operation, the continuous accumulation of particulate matter can clog the filter pores, increasing system operating resistance and reducing filtration efficiency. Existing cleaning methods (such as pulse jet cleaning and mechanical rapping) have significant limitations: pulse jet cleaning requires compressed air; mechanical rapping is incomplete and prone to creating "ash bridges."

[0003] Regarding improvements in purification efficiency, single filtration technologies struggle to achieve synergistic control of multiple pollutants. Some devices attempt to combine spray purification technology to enhance treatment effectiveness, but ordinary spray towers suffer from uneven liquid-gas distribution and short contact time, resulting in limited purification efficiency.

[0004] In conclusion, developing a gas pollution treatment device that can achieve efficient, clean, and multi-stage purification is key to overcoming current technological bottlenecks. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a real-time gas pollution treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A baffle plate is installed inside the filter chamber;

[0009] The filter bag is installed on the partition, which has an opening that fits the filter bag.

An air inlet channel is provided on one side of the filter chamber, which is connected to the pre-filter chamber. A connecting channel is installed on the filter chamber, which is connected to the post-filter chamber.

[0021] As a preferred embodiment of the present invention: one end of the outer support extends to the bottom of the filter bag, an mounting plate is fixed to the end of the outer support, a bottom plate is installed at the bottom of the filter bag, and the mounting plate and the bottom plate are connected by a second spring.

[0022] As a preferred embodiment of the present invention: one end of the connecting channel is connected to a spray purification chamber, the spray purification chamber comprising:

[0023] The ground floor chamber is connected to the connecting passageway;

[0024] The spray chamber is connected to the bottom chamber at its bottom.

[0025] The top chamber is connected to the top of the spray room, and a discharge pipe is connected to one side of the top chamber;

[0026] A spray assembly is installed in the top chamber, and a spray liquid delivery pipe is installed at the top of the top chamber. One end of the spray liquid delivery pipe is connected to the spray assembly, and a liquid output pipe is connected to the bottom of the bottom chamber. The liquid output pipe and the spray liquid delivery pipe are connected to the same spray system.

[0027] The spray chamber is provided with ribs distributed in a circular pattern.

[0028] In a preferred embodiment of the present invention, the spray chamber is provided with a plurality of baffle assemblies, the baffle assembly comprising:

[0029] A ring plate is installed on the inner wall of the spray chamber. A ring cover is connected to the inner wall of the ring plate. The center of the ring cover is raised upward and the radius gradually decreases.

[0030] The central cover is mounted on top of the annular cover via a mounting rod. The radius of the central cover is larger than the radius of the opening in the middle of the annular cover, and the central cover and the center position of the annular cover are matched.

[0031] Both the central cover and the annular plate are equipped with auxiliary spray sections.

[0032] As a preferred embodiment of the present invention, the auxiliary spray unit includes:

[0033] The mounting base has circumferentially distributed openings on the annular plate. The mounting base is installed at the bottom of the annular plate, and the position of the mounting base is adapted to the openings.

[0034] The spray head has a curved pipe at the bottom of the mounting base that bends and extends toward the center of the spray chamber. The spray head is installed at the end of the curved pipe, and when the spray head outputs water, it can spray onto the central cover below.

[0035] An annular convex edge is fixed to the outside of the central cover. The edge of the annular convex edge curves upward, and circumferentially distributed water leakage holes are opened at the connection between the annular convex edge and the central cover.

[0036] As a preferred embodiment of the present invention: a rotating shaft is installed at the bottom of the central cover, and an impeller is installed on the rotating shaft, with the impeller located at the central opening of the annular cover.

[0037] The beneficial effects of this invention are as follows:

[0038] 1. This invention, by setting up a filter bag and a deformation control component, enables polluted gas to be introduced into the filter chamber through the air inlet channel and filtered and purified by the filter bag; the purified gas is discharged through the connecting channel; the deformation control component can control the deformation of the filter bag to shake off the impurities attached to the filter bag, avoid clogging the filter pores, and ensure filtration efficiency.

[0039] 2. By setting up a deformation control component, the present invention can drive the rotating main shaft to rotate based on the operation of the motor. The second rotating arm slides outward based on centrifugal force and spring deformation, and finally contacts the inner wall of the filter bag to achieve a certain degree of impact, causing the filter bag to deform and shake off impurities. Preferably, the spherical head and the traction component are staggered in height.

[0040] 3. By setting up a traction component, the present invention can basically fix the shape of the filter bag, thereby avoiding it from being blown by the airflow, excessive deformation and blockage of the filter pores, and ensuring the filtration effect while adapting to the deformation control component.

[0041] 4. By setting a sliding traction component, the connecting ring, supported by the first spring, can maintain its original position as much as possible. With the input of airflow, it can cause the structure to move slightly to a certain extent, thereby reducing the amount of dust adhering to the filter bag. This design can reduce the working frequency of the deformation control component while ensuring the filtration effect. By setting a second spring and other structures, the connecting ring can be prevented from sliding excessively upward, so that the filter bag can maintain an effective shape as much as possible.

[0042] 5. By setting up a multi-layered baffle assembly, the present invention can extend the path of gas passage. When the spray assembly sprays, the liquid can fall onto the central hood, the annular hood, and the annular plate. The liquid flowing onto the central hood can be blocked by the annular convex edge and flow down evenly from each water leakage hole to form a water curtain. The liquid flowing onto the annular plate can be sprayed from the spray head onto the central hood below, and can also fully contact the gas in the process, thus ensuring the purification effect.

Detailed Implementation

[0051] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0052] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0053] Example 1: A real-time gas pollution treatment device, such as Figure 1-7 As shown, it includes a filter chamber 1, and a bag filter mechanism is provided inside the filter chamber 1. The bag filter mechanism includes:

[0054] Partition 15 is installed inside filter chamber 1;

[0055] A filter bag 13 is installed on a partition 15. The partition 15 has an opening that matches the filter bag 13. The filter bag 13 and the partition 15 divide the filter chamber 1 into a pre-filter chamber and a post-filter chamber. An air inlet channel 4 is provided on one side of the filter chamber 1. The air inlet channel 4 is connected to the pre-filter chamber. A connecting channel 3 is installed on the filter chamber 1. The connecting channel 3 is connected to the post-filter chamber.

[0056] Deformation control component, installed in the filter chamber, is used to control the deformation of filter bag 13;

[0057] By setting up filter bag 13 and deformation control component, polluted gas can be introduced into filter chamber 1 through air inlet channel 4 and filtered and purified by filter bag 13; the purified gas is discharged through connection channel 3; the deformation control component can be used to control the deformation of filter bag 13, thereby shaking off the impurities attached to filter bag 13, avoiding clogging of filter holes, and ensuring filtration efficiency.

[0058] To facilitate control of the deformation of filter bag 13; such as Figure 2 , Figure 3 As shown, the deformation control component includes:

[0059] Motor chamber 8, which is installed inside filter chamber 1;

[0060] Rotate the main shaft 16, which is sealed and rotates on the motor chamber 8. The bottom end of the main shaft 16 extends into the inside of the filter bag 13.

[0061] A first rotating arm 17, multiple first rotating arms 17 are distributed around the circumference of the main rotating shaft 16, a second rotating arm 19 is slidably connected to the inner wall of one end of the first rotating arm 17, a spring is connected between the end of the second rotating arm 19 and the inner wall of the first rotating arm 17, and a spherical head 18 is fixed to one end of the second rotating arm 19.

[0062] The motor chamber 8 is equipped with a motor for driving the rotating main shaft 16 to rotate.

[0063] In this embodiment, preferably, the filter bag 13 and the partition 15 divide the filter chamber 1 into a pre-filter chamber and a post-filter chamber. The inner side of the filter bag 13 and its connected upper part constitute a portion, namely the post-filter chamber. The deformation control assembly includes a motor chamber 8, a rotating main shaft 16, a first rotating arm 17, etc. The motor chamber 8 is located in the area above the filter bag 13, while the rotating main shaft 16 and the first rotating arm 17 extend into the inner side of the filter bag 13 and are both located in the post-filter chamber.

[0064] By setting up a deformation control component, the main shaft 16 can be rotated based on the operation of the motor. The second rotating arm 19 slides outward based on centrifugal force and spring deformation, and finally contacts the inner wall of the filter bag 13 to achieve a certain degree of impact, causing the filter bag 13 to deform and shake off impurities. Preferably, the spherical head 18 and the traction component are staggered in height.

[0065] In order to effectively support the filter bag 13; such as Figure 2 , Figure 3 As shown, a plurality of outer supports 10 are fixed at the bottom of the partition 15. The outer supports 10 are distributed along the circumference of the filter bag 13, and a traction component is installed between the outer supports 10 and the filter bag 13.

[0066] By setting up a traction component, the filter bag 13 can be basically shaped, thereby preventing it from being blown by the airflow, excessively deformed and blocking the filter pores, and ensuring the filtration effect while adapting to the deformation control component.

[0067] In order to effectively support the filter bag 13; such as Figure 2 , Figure 3 As shown, the traction component includes:

[0068] Connecting ring 12, the connecting ring 12 is installed on the outer bracket 10;

[0069] Pull rope 14, one end of which is fixed to the connecting ring 12, and the other end of which is fixed to the filter bag 13.

[0070] In order to effectively support the filter bag 13 and at the same time achieve a certain degree of self-cleaning of the filter bag 13; such as Figure 2 , Figure 3 As shown, the connecting ring 12 is slidably mounted on the outer wall of the outer bracket 10, and adjacent connecting rings 12 and the topmost connecting ring 12 and the partition plate 15 are connected by the first spring 9;

[0071] By setting a sliding traction component, the connecting ring 12 can remain in its original position as much as possible because it is supported by the first spring 9. With the input of airflow, the structure can be slightly moved to a certain extent, thereby reducing the amount of dust adhering to the filter bag 13. This design can reduce the working frequency of the deformation control component while ensuring the filtration effect.

[0072] In order to effectively support the filter bag 13; such as Figure 2 , Figure 3 As shown, one end of the outer bracket 10 extends to the bottom of the filter bag 13, and an mounting plate is fixed to the end of the outer bracket 10. A bottom plate is installed at the bottom of the filter bag 13, and the mounting plate and the bottom plate are connected by a second spring 11.

[0073] By setting up structures such as the second spring 11, it is possible to prevent the connecting ring 12 from sliding excessively upwards, and to keep the filter bag 13 in an effective shape as much as possible.

[0074] For further purification; such as Figure 1 , Figure 4-7 As shown, one end of the connecting channel 3 is connected to a spray purification chamber, which includes:

[0075] Bottom chamber 6, which is connected to connecting passage 3;

[0076] Spray chamber 7, the bottom of spray chamber 7 is connected to bottom chamber 6;

[0077] The top of the top chamber 2 and the top of the spray chamber 7 are connected to the top chamber 2, and a discharge pipe is connected to one side of the top chamber 2;

[0078] A spray assembly 24 is installed in the top chamber 2, and a spray liquid delivery pipe 25 is installed on the top of the top chamber 2. One end of the spray liquid delivery pipe 25 is connected to the spray assembly 24. A liquid output pipe 5 is connected to the bottom of the bottom chamber 6. The liquid output pipe 5 and the spray liquid delivery pipe 25 are connected to the same spray system.

[0079] The spray chamber 7 is provided with circumferentially distributed ribs 20.

[0080] To facilitate spray purification; such as Figure 5-7 As shown, the spray chamber 7 is equipped with multiple baffle assemblies, and the baffle assembly includes:

[0081] An annular plate 28 is installed on the inner wall of the spray chamber 7. An annular cover 22 is connected to the inner wall of the annular plate 28. The annular cover 22 is raised upward in the middle and the radius gradually decreases.

[0082] The central cover 23 is mounted on the top of the annular cover 22 via the mounting rod 29. The radius of the central cover 23 is larger than the radius of the opening in the middle of the annular cover 22, and the central cover 23 and the annular cover 22 are matched at their center positions.

[0083] Both the central cover 23 and the annular plate 28 are equipped with auxiliary spray sections.

[0084] To improve the purification effect of spraying; such as Figure 5-7 As shown, the auxiliary spray unit includes:

[0085] Mounting base 31, the annular plate 28 has circumferentially distributed openings, the mounting base 31 is installed at the bottom of the annular plate 28, and the position of the mounting base 31 is adapted to the openings;

[0086] The spray head 21 has a curved pipe at the bottom of the mounting base 31 that bends and extends toward the middle of the spray chamber 7. The spray head 21 is installed at the end of the curved pipe, and when the spray head 21 outputs water, it can spray onto the lower central cover 23.

[0087] An annular flange 30 is fixed to the outside of the central cover 23. The edge of the annular flange 30 is raised upward. A circularly distributed water leakage hole 27 is provided at the connection between the annular flange 30 and the central cover 23.

[0088] By setting up a multi-layered baffle assembly, the path of gas passage can be extended. When the spray assembly 24 sprays, the liquid can fall onto the central cover 23, the annular cover 22 and the annular plate 28. The liquid flowing onto the central cover 23 can be blocked by the annular convex edge 30 and flow down evenly from each drain hole 27 to form a water curtain. The liquid flowing onto the annular plate 28 can be sprayed from the spray head 21 onto the lower central cover 23, and can also fully contact the gas in the process, thus ensuring the purification effect.

[0089] like Figure 7 As shown, a rotating shaft is installed at the bottom of the central cover 23, and an impeller 26 is installed on the rotating shaft. The impeller 26 is located at the central opening of the annular cover 22.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
