Description

Technical Field

[0001] The present invention relates to the technical field of sewage purification and treatment, in particular to industrial waste gas purification and treatment equipment. Background Art

[0002] With the rapid development of social economy, industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes in enterprise factories. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid, lead and mercury, beryllium, smoke and productive dust. When discharged into the atmosphere, it will pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have a cumulative effect, which will more seriously endanger human health. Different substances will have different effects.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The drive motor drives the shaft on the spray box to rotate, driving the spray mechanism and fan blades on the shaft to rotate together. The rotation of the fan blades forms an airflow and generates a pressure difference, so that the industrial waste gas first enters the first purification chamber of the adsorption filter box from the air inlet. When the waste gas passes through the adsorption filter, the large particles of solid impurities in it will be blocked and separated, thereby preliminarily achieving the purification of industrial waste gas;

[0018] 2. Under the action of the airflow generated by the fan blades, the industrial waste gas passes through the adsorption filter and enters the second purification chamber through the through hole. The photocatalytic spotlight emits a high-energy electron beam to crack various pollutants such as ammonia, trimethylamine, and hydrogen sulfide in the industrial waste gas. The molecular chains of organic or inorganic polymer pollutants are cracked under the irradiation of the high-energy ultraviolet beam and oxidized into small molecular compounds, further purifying the industrial waste gas and improving the effect of purification and treatment of industrial waste gas.

[0019] 3. The airflow drives the industrial waste gas into the middle of the spray box, and the waste gas contacts and reacts with the spray liquid sprayed by the spray mechanism to further remove nitrogen oxides and sulfur dioxide in the waste gas, thereby realizing three-layer purification of industrial waste gas, treating different components in the industrial waste gas respectively, and improving the effect of purifying and treating industrial waste gas; at the same time, the rotating shaft will drive the spray mechanism to rotate around it, and the rotating spray mechanism can make the spray liquid more evenly distributed in the second purification chamber, forming a wider liquid film, so that the pollutants in the industrial waste gas have more contact opportunities with the spray liquid, thereby improving the absorption and reaction efficiency and enhancing the removal effect of pollutants in the industrial waste gas; in addition, there is no need to set up a separate power mechanism to drive the fan blades and the spray mechanism to rotate respectively, thereby reducing the space required for the installation of the power device and the cost required for production. In addition, the spray liquid and pollutants after spraying are discharged from the spray box through the sewage outlet provided at the bottom of the spray box, and the purified gas is discharged from the exhaust port;

[0020] 4. There are two adsorption filters and two spray mechanisms. The filter holes of the two adsorption filters are gradually reduced, thereby blocking larger particles and smaller particles of solid impurities in the industrial waste gas, respectively, to achieve double-layer filtration of the industrial waste gas, preventing large particles of solid impurities from clogging the filter holes and affecting the normal passage of the industrial waste gas, thereby improving the filtration efficiency and effect of the industrial waste gas; In addition, the two spray mechanisms can spray different spray liquids, thereby removing different pollutants in a targeted manner and improving the effect of purifying the air. At the same time, the two spray mechanisms and multiple fan blades are driven to rotate by the rotating shaft, further reducing the cost of installing the power device and the space required for manufacturing; At the same time, there are also multiple fan blades, which drive the normal flow of industrial waste gas in the corresponding area, avoiding the reverse flow of industrial waste gas and affecting the efficiency of industrial waste gas treatment;

[0021] At the same time, a first partition and a second partition are provided between the two spray mechanisms, and an S-shaped channel is formed between the first partition and the second partition. A filter layer is provided in the S-shaped channel to absorb the spray liquid generated by the first spray mechanism and the separated pollutants, thereby preventing the spray liquids of the two spray mechanisms from contacting each other and causing reactions, thereby improving the effect of purifying and treating industrial waste gas;

[0022] 5. When the spray mechanism or fan blades of the corresponding connecting section are damaged, open the corresponding maintenance port and remove the corresponding connecting section from the maintenance port to inspect and maintain the spray mechanism and fan blades in the corresponding area without removing the entire shaft and all the spray mechanisms, thereby improving the efficiency of subsequent inspection and maintenance of the purification treatment equipment;

[0023] After the corresponding spray mechanism and fan blades are repaired, the blocking plate is placed obliquely into the inspection port, and the direction and position of the blocking plate are adjusted in the inspection port until the blocking plate is flush with the baffle. At the same time, the first fixing rod provided on the blocking plate passes through the baffle and extends to the outside. Then, the first fixing rod, the first spring, the first sliding sleeve, the first protrusion, the first vertical slot, the first nut, the first cross brace, and the second vertical slot cooperate to limit the first sliding sleeve from sliding further on the first fixing rod. Then, the first spring between the first nut and the baffle is further compressed through the cooperation between the first nut and the first sliding sleeve. The rebound force generated by the compression of the first spring is transmitted to the blocking plate through the first nut, the first sliding sleeve, and the first fixing rod, and further compresses the sealing ring between the blocking plate and the baffle, thereby enhancing the sealing between the blocking plate and the baffle, preventing industrial waste gas from leaking out through the gap between the blocking plate and the baffle, and thus improving the effect of purifying and treating industrial waste gas.

[0024] 6. When the corresponding connecting sections need to be connected, first, the first flange is mounted on the end of one of the connecting sections, and the second flange is mounted on the end of the adjacent connecting section. Then, the first flange, the second flange, the second protrusion, the third vertical groove, the second transverse groove, and the fourth vertical groove are matched to restrict the first flange and the second flange from moving axially to one side on the corresponding connecting section.

[0025] Then, due to the tension spring pulling the two first limit blocks, they are located in the second fixing rod, so that the second fixing rod smoothly passes through the first connecting hole and the second connecting hole respectively provided in the first flange and the second flange in sequence until one end thereof contacts the first flange, and then through the cooperation between the second fixing rod, the threaded rod, the T-shaped block, the wedge block, the T-shaped slot, the second spring, the first inclined surface, and the first limit block, the other side of the first limit block contacts the second flange, and the threaded rod is further tightened to drive the first flange and the second flange to move relative to each other, and compress the third spring until the whole is in a tight state, thereby realizing a detachable connection between the connecting sections, facilitating subsequent maintenance of the spray mechanism and the fan blades on the corresponding connecting section, and improving the efficiency of maintaining the purification treatment equipment;

[0026] In addition, since the connecting sections are in an elastic connection state, the central axis deviation generated during the installation process can be compensated, ensuring stable torque transmission between the connecting sections, ensuring the stability of the overall structure, and improving the effect of purifying industrial waste gas; at the same time, the first limit block can be moved relative to the second fixed rod, so as to adjust the tightness of the third spring as needed, to avoid the third spring being too loose, resulting in repeated horizontal jumping between the connecting sections, making the overall structure unstable, and at the same time avoid the third spring being too tight, shortening the service life of the third spring, thereby improving the service life of the purification equipment;

[0027] 7. Multiple spray pipes and multiple spray ports provided on the spray pipes further increase the coverage of the spray mechanism, so that the spray liquid is more evenly distributed in the second purification chamber, forming a wider liquid film, so that pollutants in the industrial waste gas have more contact opportunities with the spray liquid, thereby improving the absorption and reaction efficiency and enhancing the removal effect of pollutants in the industrial waste gas; the rotating shaft is provided with a plurality of water outlets used in conjunction with the water inlet, specifically connected to the corresponding pipelines for conveying the corresponding spray liquid; the rotating shaft is provided with a limiting mechanism for limiting the sliding of the second sliding sleeve on the rotating shaft, fixing the spray mechanism on the rotating shaft;

[0028] When the second stop block is in the axial direction of the rotating shaft, the third stop block is restrained from moving relative to the second sleeve, and the third stop block is restrained from moving relative to the fourth sleeve, thereby restraining the movement of the spray mechanism on the rotating shaft and achieving the fixation of the spray mechanism on the rotating shaft. At the same time, due to the rotation of the second stop block relative to the second sleeve, the third stop block no longer corresponds to the fourth stop block. At the same time, through the cooperation between the fourth spring, the second nut, the third sleeve and the first stop block, the second sleeve is driven to move relative to the second stop block until the fourth stop block provided on the second sleeve contacts the second stop block. In addition, at this time, the side surface of the third stop block contacts the fourth stop block. The resistance generated after the contact will limit the second stop block from rotating in the opposite direction on the rotating shaft, thereby preventing the external force from inadvertently driving the second stop block to rotate in the opposite direction, affecting the stability of the spray mechanism fixed on the rotating shaft, thereby improving the service life of the purification equipment.

[0029] Finally, by rotating the second nut on the third sleeve, the third spring is further compressed. The rebound force generated by the compression of the third spring will limit the movement of the second sleeve relative to the second limit block, thereby further improving the stability of the spray mechanism fixed on the rotating shaft and increasing the service life of the purification equipment.

[0048] The present invention provides an industrial waste gas purification and treatment equipment, such as Figure 1 and Figure 2 As shown, it includes an adsorption filter box 2 and a spray box 3 arranged on a base frame 1, and the adsorption filter box 2 and the spray box 3 are respectively provided with an air inlet 4 and an air outlet 5; the adsorption filter box 2 is provided with a first purification chamber 6 connected to the air inlet 4, and an adsorption filter screen 7 is provided in the first purification chamber 6.

One side is fixedly connected thereto, and a photocatalytic spotlight 9 is provided at the end of the spray box 3, as well as a plurality of through holes 10 communicating with the first purification chamber 6 and the second purification chamber 8. For details, reference can be made to the photocatalytic ultraviolet lamp of the ESGU-150W model. The photocatalytic spotlight 9 emits a high-energy electron beam to crack ammonia, trimethylamine, hydrogen sulfide and other pollutants in the industrial waste gas, so that the molecular chains of organic or inorganic polymer pollutants are cracked under the irradiation of the high-energy ultraviolet beam and oxidized into small molecular compounds, thereby further achieving the purification of industrial waste gas and improving the effect of purifying and treating industrial waste gas;

[0049] The spray box 3 is rotatably connected to a rotating shaft 11, on which a spray mechanism 12 and a fan blade 13 are provided. The rotating shaft 11 is driven by a driving motor 14 to rotate on the spray box 3, driving the spray mechanism 12 and the fan blade 13 provided on the rotating shaft 11 to rotate together. The rotation of the fan blade 13 forms an air flow and generates a pressure difference, thereby driving the industrial waste gas to flow in a directional manner in the purification treatment equipment, avoiding the reverse flow of the industrial waste gas and affecting the efficiency of treating the industrial waste gas; at the same time, the rotating shaft 11 drives the spray mechanism 12 to rotate around it, and the rotating spray mechanism 12 can make the spray liquid more evenly distributed in the second purification chamber 8, forming a wider The liquid film makes the pollutants in the industrial waste gas have more contact opportunities with the spray liquid, thereby improving the absorption and reaction efficiency and enhancing the removal effect of pollutants in the industrial waste gas; in addition, there is no need to set up separate power mechanisms to drive the fan blades 13 and the spray mechanism 12 to rotate respectively, thereby reducing the space required for the installation of the power device and the cost required for production; it also includes a drive motor 14 arranged on the spray box 3, the movable end of the drive motor 14 is connected to the rotating shaft 11, which increases the power for the rotation of the rotating shaft 11 on the spray box 3, and a sewage outlet 15 is provided at the bottom of the spray box 3 to discharge the spray liquid and pollutants after spraying out of the spray box 3.

[0050] Preferably, Figure 2 As shown, there are two adsorption filters 7 and spray mechanisms 12. Specifically, the filter holes of the two adsorption filters 7 are changed from large to small, thereby respectively blocking larger particles and smaller particles of solid impurities in the industrial waste gas, thereby achieving double-layer filtration of the industrial waste gas, avoiding large particles of solid impurities clogging the filter holes and affecting the normal passage of the industrial waste gas, thereby improving the filtration efficiency and effect of the industrial waste gas; in addition, the two spray mechanisms 12 can spray different spray liquids, thereby removing different pollutants in a targeted manner and improving the effect of purifying the air. At the same time, the two spray mechanisms 12 and the plurality of fan blades 13 are driven by the rotating shaft 11 Its rotation further reduces the cost of installing the power unit and the space required for manufacturing; a first partition plate 16 and a second partition plate 17 are provided between the two spray mechanisms 12, and an S-shaped channel 18 is formed between the first partition plate 16 and the second partition plate 17. A filter layer 19 is provided in the S-shaped channel 18 to prevent the spray liquids of the two spray mechanisms 12 from contacting each other and producing reactions, thereby improving the effect of purifying and treating industrial waste gas; there are multiple fan blades 13, which respectively drive the normal flow of industrial waste gas in the corresponding area to avoid the reverse flow of industrial waste gas, which affects the efficiency of treating industrial waste gas.

[0051] Preferably, Figure 2 and Figure 3As shown, a plurality of inspection ports 20 are provided on one side of the spray box 3, and the rotating shaft 11 includes a plurality of connecting sections 21, one of which is connected to the movable end of the drive motor 14, and the spray mechanism 12 and the fan blades 13 are connected to the remaining connecting sections 21. A connecting mechanism is provided between two adjacent connecting sections 21. By releasing the connecting mechanism of the corresponding connecting section 21, the corresponding connecting section 21 can be easily removed from the inspection port 20, thereby inspecting and maintaining the spray mechanism 12 and the fan blades 13 in the corresponding area, thereby improving the efficiency of subsequent inspection and maintenance of the purification treatment equipment.

[0052] Preferably, Figure 3 As shown, the inspection port 20 is provided with a blocking plate 22 for blocking the inspection port 20 to prevent direct leakage of industrial waste gas. The blocking plate 22 is provided with a reinforcing rib 23 to further strengthen the strength of the blocking plate 22. The end of the inspection port 20 is provided with a baffle 24 in contact with the blocking plate 22. A sealing ring 25 is provided between the baffle 24 and the blocking plate 22, including a plurality of first nuts 26 and a plurality of first fixing rods 27 provided on the blocking plate 22. The first fixing rod 2 7 passes through the baffle 24 and extends to the outside and is connected with the first nut 26, thereby fixing the blocking plate 22 on the baffle 24. Specifically, the baffle 24 is arranged on the outside of the blocking plate 22. The pressure of the industrial waste gas first acts on the blocking plate 22, and then further squeezes the sealing ring 25 between the blocking plate 22 and the baffle 24, thereby enhancing the sealing between the blocking plate 22 and the baffle 24, preventing the industrial waste gas from leaking out through the gap between the blocking plate 22 and the baffle 24, and thus improving the effect of purifying the industrial waste gas.

[0053] Preferably, Figure 3 and Figure 4As shown, the first fixing rod 27 is provided with a first vertical slot 28 and a second vertical slot 29, and a first transverse slot 30 connecting the first vertical slot 28 and the second vertical slot 29, and a first sliding sleeve 31 is also slidably arranged on the first fixing rod 27, and the first sliding sleeve 31 is provided with a first protrusion 32, and the first protrusion 32 is slidably arranged between the first vertical slot 28, the second vertical slot 29 and the first transverse slot 30 in sequence, and the first nut 26 is threadedly arranged on the first sliding sleeve 31, and a first spring 33 is provided between the first nut 26 and the blocking plate 22. After the maintenance is completed, the blocking plate 22 is obliquely placed into the inspection port 20, and The direction and position of the blocking plate 22 are adjusted in the inspection port 20 until the blocking plate 22 is flush with the baffle 24. At the same time, the first fixing rod 27 provided on the blocking plate 22 passes through the baffle 24 and extends to the outside. Then, the first spring 33 and the first sliding sleeve 31 are sequentially sleeved on the first fixing rod 27. Then, external force is applied to slide the first sliding sleeve 31 on the first fixing rod 27, so that the first protrusion 32 provided on the first sliding sleeve 31 slides in the first vertical groove 28 and contacts the first spring 33 through the first nut 26 provided on the first sliding sleeve 31, compressing the first spring 33 until the first protrusion 32 slides to the first horizontal groove 28. The first sleeve 31 is then rotated to make the first protrusion 32 slide in the first horizontal support until the first protrusion 32 slides into the second vertical slot 29. The force applied to the first fixing rod 27 is then canceled. Under the action of the rebound force generated by the compression of the first spring 33, the first sleeve 31 slides in the opposite direction on the first fixing rod 27, making the first protrusion 32 slide in the second vertical slot 29 until the first protrusion 32 contacts the first fixing rod 27. The resistance generated after the contact limits the first sleeve 31 from sliding further on the first fixing rod 27. The first nut 26 is then rotated on the first sleeve 31. Since the first nut 26 is threadedly connected to the first sleeve 31, the first nut 26 moves on the first sleeve 31 and further compresses the first spring 33 between the first nut 26 and the baffle 24. The rebound force generated by the compression of the first spring 33 is transmitted to the sealing plate 22 through the first nut 26, the first sleeve 31, and the first fixing rod 27, and further compresses the sealing ring 25 between the sealing plate 22 and the baffle 24, thereby enhancing the sealing between the sealing plate 22 and the baffle 24, preventing industrial waste gas from leaking out through the gap between the sealing plate 22 and the baffle 24, and thereby improving the effect of purifying and treating industrial waste gas.

The first flange 34 and the second flange 35 are respectively provided with the second protrusion 39 on the first flange 34 and the second flange 35 so as to slide in the third vertical groove 36 until the second protrusion 39 slides into the second transverse groove 38. Then, the first flange 34 and the second flange 35 are rotated so as to slide the second protrusion 39 in the second transverse support until the second protrusion 39 slides into the fourth vertical groove 37. Then, the first flange 34 and the second flange 35 are respectively slid on the corresponding connecting section 21 in the opposite direction so as to slide the second protrusion 39 in the fourth vertical groove 37 until the second protrusion 39 contacts the corresponding connecting section 21, thereby limiting the first flange 34 and the second flange 35 moves axially to one side on the corresponding connecting section 21, and then the second fixing rod 40 passes through the first connecting hole 41 and the second connecting hole 42 respectively provided in the first flange 34 and the second flange 35 until one end thereof contacts the first flange 34, and then the first limit block 43 is driven to move on the second fixing rod 40 so that one side thereof contacts the second flange 35, thereby limiting the axial movement of the first flange 34 and the second flange 35 on the corresponding connecting section 21, realizing the detachable connection of the corresponding connecting section 21, facilitating the subsequent maintenance of the spray mechanism 12 and the fan blade 13 on the corresponding connecting section 21, and improving the efficiency of maintaining the purification treatment equipment.

[0055] Preferably, Figure 8As shown, a wedge block 44 and a slider 45 are slidably connected to the second fixing rod 40, and the two sides of the wedge block 44 are respectively provided with a first inclined surface 46 that contacts one side of the first limit block 43, and the slider 45 contacts the other side of the first limit block 43. A second spring 47 is provided between the slider 45 and the second fixing rod 40, and a tension spring 48 is provided between the two first limit blocks 43. A threaded rod 49 is threadedly connected to the second fixing rod 40, and a T-shaped block 50 is provided at the end of the threaded rod 49. The wedge block 44 is provided with a second spring 47 that contacts the T-shaped block 5 0 is connected to the T-shaped slot 51, and both sides of the T-shaped block 50 are in contact with the wedge block 44 respectively. A third spring 52 is provided between the first flange 34 and the second flange 35. By rotating the threaded rod 49 on the second fixing rod 40, the threaded rod 49 is threadedly connected to the second fixing rod 40, so that the threaded rod 49 moves on the second fixing rod 40, and the T-shaped block 50 provided at the end of the threaded rod 49 contacts the wedge block 44, and the component force generated drives the wedge block 44 to move together. At the same time, due to the T-shaped slot 51 provided on the wedge block 44 and the T-shaped The block 50 is rotated to prevent the threaded rod 49 from driving the wedge block 44 to rotate together, thereby ensuring that the first inclined surfaces 46 provided on both sides of the wedge block 44 are in contact with one side of the first limit block 43. The component force generated after the contact drives the first limit block 43 to move on the second fixed rod 40. At the same time, the other side of the first limit block 43 contacts the slider 45, driving it to move together and compressing the second spring 47. The resistance generated by the compression of the second spring 47 is transmitted to the first limit block 43 through the slider 45, limiting it from continuing to slide down. When the first inclined surface 46 contacts the first limit block 4 The component force generated by the tension spring 48 is sufficient to overcome the rebound force generated by the tension spring 48, driving the two first limit blocks 43 to move outward on the second fixing rod 40 until the other side of the first limit block 43 contacts the second flange 35. The threaded rod 49 is further tightened to drive the first flange 34 and the second flange 35 to move relative to each other and compress the third spring 52 until the whole is in a taut state, thereby realizing a detachable connection between the connecting sections 21, facilitating subsequent maintenance of the spray mechanism 12 and the fan blade 13 on the corresponding connecting section 21, and improving the efficiency of maintaining the purification treatment equipment.

[0056] In addition, since the connecting sections 21 are in an elastically connected state, the central axis deviation generated during the installation process can be compensated, ensuring stable torque transmission between the connecting sections 21, ensuring the stability of the overall structure, and improving the effect of purifying industrial waste gas; at the same time, the first limit block 43 can move relative to the second fixed rod 40, so as to adjust the tightness of the third spring 52 as needed, to avoid the third spring 52 being too loose, resulting in repeated horizontal jumping between the connecting sections 21, making the overall structure in an unstable state, and at the same time avoid the third spring 52 being too tight, shortening the service life of the third spring 52, thereby improving the service life of the purification equipment.

[0057] Preferably, Figure 2 and Figure 5 As shown, the spray mechanism 12 includes several spray pipes 53 and two second sleeves 54 keyed to the rotating shaft 11. The second sleeve 54 is provided with several support rods 55 connected to the spray pipe 53. The spray pipe 53 is provided with a water inlet 56 and several spray ports 57. The multiple spray pipes 53 and the multiple spray ports 57 arranged on the spray pipe 53 further increase the coverage of the spray mechanism 12, so that the spray liquid is more evenly distributed in the second purification chamber 8, forming a wider liquid film, so that the pollutants in the industrial waste gas have more contact opportunities with the spray liquid, thereby improving the absorption and reaction efficiency and enhancing the removal effect of pollutants in the industrial waste gas; the rotating shaft 11 is provided with several water outlets 58 used in conjunction with the water inlet 56, which are specifically connected to the corresponding pipelines for conveying the corresponding spray liquid; the rotating shaft 11 is provided with a limiting mechanism for limiting the sliding of the second sleeve 54 on the rotating shaft 11, fixing the spray mechanism 12 on the rotating shaft 11.

[0058] Preferably, Figures 9-11As shown, the limiting mechanism includes a second limiting block 59 and a third sliding sleeve 60 slidably arranged on the rotating shaft 11, the rotating shaft 11 and the second sliding sleeve 54 are respectively provided with a plurality of first key grooves 61 and second key grooves 62, one side of the third sliding sleeve 60 is provided with a plurality of connecting keys 63 that are in sliding contact with the first key groove 61 and the second key groove 62, the end of the connecting key 63 is provided with a first protrusion 64 that contacts the second sliding sleeve 54, the second limiting block 59 is provided with a second protrusion 65 that is slidably connected with the first key groove 61, the rotating shaft 11 is provided with a limiting groove 66 that is snap-fitted with the second protrusion 65, the second limiting block 59 is provided with a plurality of third protrusions 67, the second sliding sleeve 54 is provided with a plurality of fourth protrusions 68 that contact the second protrusion 65, the ends of the fourth protrusion 68 are respectively in contact with the second limiting block 59 and the third protrusion 67, the third sliding sleeve 60 is provided with a second nut 69, and a fourth protrusion 68 is provided between the second nut 69 and the second limiting block 59. After the maintenance of the spring 70 and the spray mechanism 12 is completed, the connecting key 63 provided on one side of the third sliding sleeve 60 is slightly bent to slightly deform it, so that the connecting key 63 passes through the second limit block 59 and the second sliding sleeve 54 in sequence. When the end of the connecting key 63 passes through the second sliding sleeve 54, the external force is removed to restore it, so that the first protrusion 64 provided on the end of the connecting key 63 contacts the second sliding sleeve 54, and the connecting key 63 falls into the second key groove 62 provided on the second sliding sleeve 54, and at the same time passes through the second limit block 59. The third protrusion 67 provided on the upper portion contacts the fourth protrusion 68 provided on the other side of the second sliding sleeve 54, limiting the third sliding sleeve 60 from sliding axially relative to the second sliding sleeve 54. Then, the second sliding sleeve 54, the second limit block 59 and the third sliding sleeve 60 are sleeved on the rotating shaft 11, so that the connecting key 63 corresponds to the first key groove 61 provided on the rotating shaft 11. As a result, the torque generated by the rotating shaft 11 is transmitted to the second sliding sleeve 54 through the connecting key 63, driving the spray mechanism 12 to rotate along with the rotating shaft 11.

[0059] When the spray mechanism 12 moves to the corresponding position, the second limit block 59 is rotated on the third sliding sleeve 60 so that the second protrusion 65 provided on the second limit block 59 enters the limiting groove 66 from the first key groove 61. The resistance generated by the contact between the two sides of the second protrusion 65 and the limiting groove 66 will limit the axial movement of the second limit block 59 on the rotating shaft 11, thereby limiting the movement of the spray mechanism 12 on the rotating shaft 11, thereby achieving the fixation of the spray mechanism 12 on the rotating shaft 11; at the same time, the second limit block 59 will rotate relative to the second sliding sleeve 54, so that the third protrusion 67 no longer corresponds to the fourth protrusion 68. Under the action of the rebound force generated by the compression of the fourth spring 70, the force is transmitted through the second nut 69, the third sliding sleeve 60 and the first protrusion 64, driving the second sliding sleeve 54 relative to the second limit The block 59 moves until the fourth protrusion 68 provided on the second sleeve 54 contacts the second limit block 59. In addition, at this time, the side of the third protrusion 67 contacts the fourth protrusion 68. The resistance generated after the contact will limit the second limit block 59 from rotating in the opposite direction on the rotating shaft 11, thereby avoiding the external force from inadvertently driving the second limit block 59 to rotate in the opposite direction, affecting the stability of the spray mechanism 12 fixed on the rotating shaft 11, thereby improving the service life of the purification equipment; finally, by rotating the second nut 69 on the third sleeve 60, the third spring 52 is further compressed. The rebound force generated by the compression of the third spring 52 will limit the movement of the second sleeve 54 relative to the second limit block 59, thereby further improving the stability of the spray mechanism 12 fixed on the rotating shaft 11, thereby improving the service life of the purification equipment.

[0060] Preferably, Figure 2 As shown, one side of the adsorption filter box 2 is detachably connected to a flange cover 71, which is specifically connected to the flange plate and the adsorption filter box 2 by bolts and nuts, so as to facilitate subsequent disassembly and remove the adsorption filter 7 for replacement. The adsorption filter box 2 and the flange cover 71 are respectively provided with positioning grooves 72 which are slidably connected to the adsorption filter 7, which play a positioning role in fixing the adsorption filter 7 in the adsorption filter box 2. A sealing strip 73 in contact with the adsorption filter box 7 is provided in the positioning groove 72 to prevent industrial waste gas from directly passing through the gap between the adsorption filter 7 and the adsorption filter box 2, thereby improving the effect of purifying and treating industrial waste gas.

[0061] Example 1

[0062] The present invention provides an industrial waste gas purification and treatment equipment, such as Figure 1 and Figure 2As shown, the driving motor 14 drives the rotating shaft 11 to rotate on the spray box 3, driving the spray mechanism 12 and the fan blades 13 provided on the rotating shaft 11 to rotate together. The rotation of the fan blades 13 forms an airflow and generates a pressure difference, so that the industrial waste gas first enters the first purification chamber 6 provided in the adsorption filter box 2 through the air inlet 4. When the waste gas passes through the adsorption filter 7, the large particles of solid impurities therein will be blocked and separated, thereby preliminarily achieving the purification of the industrial waste gas.

[0063] Under the action of the airflow generated by the fan blades 13, the industrial waste gas passes through the adsorption filter 7 and enters the second purification chamber 8 through the through hole 10. The high-energy electron beam emitted by the photocatalytic spotlight 9 decomposes various pollutants such as ammonia, trimethylamine, and hydrogen sulfide in the industrial waste gas. The molecular chains of organic or inorganic high-molecular pollutants are decomposed under the irradiation of the high-energy ultraviolet beam and oxidized into small molecular compounds, thereby further purifying the industrial waste gas and improving the effect of purifying and treating the industrial waste gas.

[0064] Finally, the airflow drives the industrial waste gas into the middle of the spray box 3, and the waste gas contacts and reacts with the spray liquid sprayed by the spray mechanism 12 to further remove nitrogen oxides and sulfur dioxide in the waste gas, thereby realizing three-layer purification of industrial waste gas, treating different components in the industrial waste gas respectively, and improving the effect of purifying and treating industrial waste gas; at the same time, the rotating shaft 11 will drive the spray mechanism 12 to rotate around it, and the rotating spray mechanism 12 can make the spray liquid more evenly distributed in the second purification chamber 8, forming a wider liquid film, so that the pollutants in the industrial waste gas have more contact opportunities with the spray liquid, thereby improving the absorption and reaction efficiency and enhancing the removal effect of pollutants in the industrial waste gas; in addition, there is no need to set up a separate power mechanism to drive the fan blades 13 and the spray mechanism 12 to rotate respectively, thereby reducing the space required for the installation of the power device and the cost required for production. In addition, the spray liquid and pollutants after spraying are discharged from the spray box 3 through the sewage outlet 15 provided at the bottom of the spray box 3, and the purified gas is discharged from the exhaust port.

[0065] Example 2

[0066] On the basis of Example 1, Figure 2As shown, there are two adsorption filters 7 and spray mechanisms 12, and the filter holes of the two adsorption filters 7 are gradually reduced, thereby respectively blocking larger particles and smaller particles of solid impurities in the industrial waste gas, thereby achieving double-layer filtration of the industrial waste gas, preventing large particles of solid impurities from clogging the filter holes and affecting the normal passage of the industrial waste gas, thereby improving the filtration efficiency and effect of the industrial waste gas; in addition, the two spray mechanisms 12 can spray different spray liquids, thereby removing different pollutants in a targeted manner and improving the effect of purifying the air. At the same time, the two spray mechanisms 12 and the multiple fan blades 13 are driven to rotate by the rotating shaft 11, further reducing the cost of installing the power device and the space required for manufacturing; at the same time, there are also multiple fan blades 13, which respectively drive the normal flow of industrial waste gas in the corresponding area, avoiding the reverse flow of industrial waste gas, which affects the efficiency of treating industrial waste gas;

[0067] At the same time, a first partition plate 16 and a second partition plate 17 are provided between the two spraying mechanisms 12. An S-shaped channel 18 is formed between the first partition plate 16 and the second partition plate 17. A filter layer 19 is provided in the S-shaped channel 18 to absorb the spray liquid generated by the first spraying mechanism 12 and the separated pollutants, thereby preventing the spray liquids of the two spraying mechanisms 12 from contacting each other and causing reactions, thereby improving the purification effect of the industrial waste gas.

[0068] Example 3

[0069] On the basis of Example 2, Figure 1 、 Figure 3 and Figure 4 As shown, when the spray mechanism 12 or the fan blade 13 of the corresponding connecting section 21 is damaged, the corresponding inspection port 20 is opened and the corresponding connecting section 21 is removed from the inspection port 20, thereby inspecting and maintaining the spray mechanism 12 and the fan blade 13 in the corresponding area without having to remove the entire rotating shaft 11 and all the spray mechanisms 12, thereby improving the efficiency of subsequent inspection and maintenance of the purification treatment equipment;

[0070] After the first nut 26 provided on the first sleeve 31 contacts with the first spring 33, the first spring 33 is compressed until the first protrusion 32 slides into the first transverse groove 30, and then the first sleeve 31 is rotated to make the first protrusion 32 slide in the first transverse support until the first protrusion 32 slides into the second vertical groove 29, and then the force applied to the first fixing rod 27 is canceled. The first nut 26 is then rotated on the first sleeve 31. Since the first nut 26 is threadedly connected to the first sleeve 31, the first nut 26 moves on the first sleeve 31 and further compresses the first spring 33 between the first nut 26 and the baffle 24. The rebound force generated by the compression of the first spring 33 is transmitted to the sealing plate 22 through the first nut 26, the first sleeve 31, and the first fixing rod 27, and further compresses the sealing ring 25 between the sealing plate 22 and the baffle 24, thereby enhancing the sealing between the sealing plate 22 and the baffle 24, preventing industrial waste gas from leaking out through the gap between the sealing plate 22 and the baffle 24, and thus improving the effect of purifying and treating industrial waste gas.

[0071] Example 4

[0072] On the basis of Example 2, Figure 5-Figure 8As shown, when the corresponding connecting sections 21 need to be connected, the first flange 34 is first sleeved on the end of one of the connecting sections 21, and the second flange 35 is sleeved on the end of the adjacent connecting section 21. Then, the first flange 34 and the second flange 35 are respectively slid on the corresponding connecting section 21, so that the second protrusions 39 provided on the first flange 34 and the second flange 35 respectively slide in the third vertical groove 36 until the second protrusions 39 slide into the second transverse groove 38. Then, the first flange 34 and the second flange 35 are rotated so that the second protrusions 39 slide in the second transverse support until the second protrusions 39 slide into the fourth vertical groove 37. Then, the first flange 34 and the second flange 35 are respectively slid on the corresponding connecting section 21 in the opposite direction so that the second protrusions 39 slide in the fourth vertical groove 37 until the second protrusions 39 contact the corresponding connecting section 21, thereby limiting the first flange 34 and the second flange 35 from moving axially to one side on the corresponding connecting section 21.

[0073] Then, due to the tension spring 48 pulling the two first limit blocks 43, it is located in the second fixing rod 40, so that the second fixing rod 40 passes through the first connecting hole 41 and the second connecting hole 42 respectively provided in the first flange 34 and the second flange 35, until one end thereof contacts the first flange 34. Then, by rotating the threaded rod 49 on the second fixing rod 40, the threaded rod 49 is threadedly connected to the second fixing rod 40, so that the threaded rod 49 moves on the second fixing rod 40, and contacts the wedge block 44 through the T-shaped block 50 provided at the end of the threaded rod 49. The component force generated drives the wedge block 44 to move together. At the same time, due to the T-shaped groove 51 provided on the wedge block 44 and the rotation connection with the T-shaped block 50, the threaded rod 49 is prevented from driving the wedge block 44 to rotate together, thereby ensuring that the first inclined surfaces 46 provided on both sides of the wedge block 44 contact one side of the first limit block 43. The component force generated after the contact drives The first limit block 43 moves on the second fixed rod 40, and at the same time, the other side of the first limit block 43 contacts the slider 45, driving it to move together and compressing the second spring 47. The resistance generated by the compression of the second spring 47 is transmitted to the first limit block 43 through the slider 45, limiting it from continuing to slide down. When the component force generated by the first inclined surface 46 and the first limit block 43 is sufficient to overcome the rebound force generated by the tension spring 48, the two first limit blocks 43 will be driven to move outward on the second fixed rod 40 until the other side of the first limit block 43 contacts the second flange 35. The threaded rod 49 is further tightened to drive the first flange 34 and the second flange 35 to move relative to each other and compress the third spring 52 until the whole is in a tight state, thereby realizing a detachable connection between the connecting sections 21, facilitating subsequent maintenance of the spray mechanism 12 and the fan blades 13 on the corresponding connecting section 21, and improving the efficiency of maintaining the purification treatment equipment;

[0074] In addition, since the connecting sections 21 are in an elastically connected state, the central axis deviation generated during the installation process can be compensated, ensuring stable torque transmission between the connecting sections 21, ensuring the stability of the overall structure, and improving the effect of purifying industrial waste gas; at the same time, the first limit block 43 can move relative to the second fixed rod 40, so as to adjust the tightness of the third spring 52 as needed, to avoid the third spring 52 being too loose, resulting in repeated horizontal jumping between the connecting sections 21, making the overall structure in an unstable state, and at the same time avoid the third spring 52 being too tight, shortening the service life of the third spring 52, thereby improving the service life of the purification equipment.

[0075] Example 5

[0076] On the basis of Example 1, Figure 5 、 Figure 9 、 Figure 10 and Figure 11 As shown, multiple spray pipes 53 and multiple spray ports 57 provided on the spray pipes 53 further increase the coverage of the spray mechanism 12, so that the spray liquid is more evenly distributed in the second purification chamber 8, forming a wider liquid film, so that pollutants in the industrial waste gas have more opportunities to contact with the spray liquid, thereby improving the absorption and reaction efficiency and enhancing the removal effect of pollutants in the industrial waste gas; the rotating shaft 11 is provided with a plurality of water outlets 58 used in conjunction with the water inlet 56, which are specifically connected to corresponding pipes for conveying corresponding spray liquid; the rotating shaft 11 is provided with a limiting mechanism for limiting the sliding of the second sliding sleeve 54 on the rotating shaft 11, fixing the spray mechanism 12 on the rotating shaft 11;

[0077] When the spray mechanism 12 needs to be installed, the connecting key 63 provided on one side of the third sliding sleeve 60 is slightly bent to slightly deform it, so that the connecting key 63 passes through the second limit block 59 and the second sliding sleeve 54 in sequence. When the end of the connecting key 63 passes through the second sliding sleeve 54, the external force is removed to restore it, so that the first protrusion 64 provided on the end of the connecting key 63 contacts the second sliding sleeve 54, and the connecting key 63 falls into the second key groove 62 provided on the second sliding sleeve 54. At the same time, the third protrusion 67 provided on the second limit block 59 contacts the fourth protrusion 68 provided on the other side of the second sliding sleeve 54, limiting the third sliding sleeve 60 from sliding axially relative to the second sliding sleeve 54. Then, the second sliding sleeve 54, the second limit block 59 and the third sliding sleeve 60 are sleeved on the rotating shaft 11, so that the connecting key 63 corresponds to the first key groove 61 provided on the rotating shaft 11, so that the torque generated by the rotating shaft 11 is transmitted to the second sliding sleeve 54 through the connecting key 63, driving the spray mechanism 12 to rotate along with the rotating shaft 11;

[0078] When the spray mechanism 12 moves to the corresponding position, the second limit block 59 is rotated on the third sliding sleeve 60, so that the second protrusion 65 provided on the second limit block 59 enters the limiting groove 66 from the first key groove 61. The resistance generated by the contact between the two sides of the second protrusion 65 and the limiting groove 66 will limit the axial movement of the second limit block 59 on the rotating shaft 11, thereby limiting the movement of the spray mechanism 12 on the rotating shaft 11, thereby achieving the fixation of the spray mechanism 12 on the rotating shaft 11; at the same time, the second limit block 59 will rotate relative to the second sliding sleeve 54, so that the third protrusion 67 no longer corresponds to the fourth protrusion 68, and the fourth spring 70 Under the action of the rebound force generated after compression, the force is transmitted through the second nut 69, the third sleeve 60 and the first protrusion 64, driving the second sleeve 54 to move relative to the second limit block 59 until the fourth protrusion 68 provided on the second sleeve 54 contacts the second limit block 59. In addition, at this time, the side surface of the third protrusion 67 contacts the fourth protrusion 68. The resistance generated after the contact will limit the second limit block 59 from rotating in the opposite direction on the rotating shaft 11, thereby preventing the second limit block 59 from being accidentally driven to rotate in the opposite direction by external force, affecting the stability of the spray mechanism 12 fixed on the rotating shaft 11, thereby improving the service life of the purification treatment equipment.

[0079] Finally, by rotating the second nut 69 on the third sleeve 60, the third spring 52 is further compressed. The rebound force generated by the compression of the third spring 52 will limit the movement of the second sleeve 54 relative to the second limit block 59, thereby further improving the stability of the spray mechanism 12 fixed on the rotating shaft 11 and improving the service life of the purification equipment.
