Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and particularly relates to a catalytic waste gas comprehensive treatment and purification device. Background Art

[0002] In the catalytic treatment of waste gas, the photo-oxygen catalytic technology uses ultraviolet light with a specific wavelength to irradiate a photocatalyst (such as titanium dioxide, etc.) to react with harmful substances in the waste gas for photo-oxygen catalysis; however, in the prior art, whenever the waste gas treatment device is used for a period of time, the waste gas treatment time becomes longer. The reason for this is that the waste gas often contains impurities (such as dust), and the impurities will cover the ultraviolet lamp. Ultraviolet light has weak penetrability, and these particles will absorb or reflect ultraviolet light, resulting in a weakened irradiation intensity of the ultraviolet light on the molecules in the waste gas. At the same time, the waste gas carries various pollutants, and direct contact with the ultraviolet lamp will cause pollution and damage to the ultraviolet lamp itself, reducing the service life and performance of the ultraviolet lamp.

[0003] After retrieval, in the prior art, a photo-oxygen waste gas treatment device with a publication number of CN219424115U has a lamp holder, a filter plate, and a carbon plate fixedly connected to the mounting plate. The purpose of setting the lamp holder is to facilitate the installation of the ultraviolet lamp tube, and the purpose of setting the filter plate is to filter the dust carried in the waste gas. Pull the sealing plate to a suitable position, and then check whether the ultraviolet lamp, filter plate, and carbon plate inside need to be replaced, and clean the accumulated dust on the equipment; this device has problems. The ultraviolet lamp is arranged on the side of the intake pipe, and the waste gas directly rushes onto the ultraviolet lamp, and then passes through the filter plate and the carbon plate for filtration, resulting in the ultraviolet lamp being easily covered with dust. After being used for a period of time, the dust covers the ultraviolet lamp and blocks it, affecting photo-oxygen catalysis and weakening the irradiation degree.

[0004] After retrieval, in the prior art, a circulating photo-catalytic oxidation device with a publication number of CN221471358U has three catalytic mechanisms distributed in an alternating manner, which extends the waste gas flow path, thereby reducing the waste gas flow rate. Then, multiple catalytic mesh plates cooperate with two UV ultraviolet lamps for oxidation treatment. This solution has problems. Affected by the catalytic mechanisms distributed in an alternating manner, the waste gas flow path is increased. Although the irradiation time is lengthened, it also gives the impurities in the waste gas time to fall, resulting in the impurities in the waste gas falling onto the ultraviolet lamp at the lower end, covering the ultraviolet lamp, weakening the irradiation intensity of the ultraviolet lamp, affecting the photo-oxygen catalysis of the waste gas, reducing the equipment cleaning interval, and requiring frequent cleaning of the surface of the ultraviolet lamp. Summary of the Invention

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a catalytic exhaust gas comprehensive treatment and purification device. By setting a particulate matter treatment mechanism, when the exhaust gas enters through the air inlet, the particulate matter in the exhaust gas is filtered through the particulate matter treatment mechanism, thereby reducing the working intensity of the filtering mechanism, increasing the use time of filtering materials such as activated carbon in the filtering mechanism, and further filtering the impurities in the exhaust gas through the filtering materials in the rear-end filtering mechanism. Finally, the molecules in the exhaust gas are subjected to a photo-oxidation reaction through an ultraviolet lamp, thereby reducing the coverage of the ultraviolet lamp by impurities in the exhaust gas, thereby increasing the service life and irradiation effect of the ultraviolet lamp.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] The filter plate assembly includes a sliding base, the bottom plate of the sliding base is composed of evenly arranged horizontal plates, a metal sintered filter plate is provided on the sliding base, the upper end of the sliding base is hingedly connected to a connecting plate III, a U-shaped bracket is slidably connected to the connecting plate III, a limiting bolt is provided at the upper end of the U-shaped bracket, and the lower end of the bolt cooperates with the connecting plate III to limit the spacing between the U-shaped brackets between the connecting plates III.

[0009] The sliding base is provided with sliding wheels. At the same time, support shafts are provided on both sides of the sliding base. The ends of the support shafts are connected to the sliding wheel shafts. The diameter of the rear sliding wheel is larger than that of the front sliding wheel. A limiting assembly is provided at the open end of the sliding groove. The sliding groove limiting assembly is used to limit the large-diameter sliding wheel on the rear side to prevent the large-diameter sliding wheel from leaving the sliding groove.

[0010] The filtering mechanism includes an installation box, which is connected to the shell, and a placement box is slidably connected to the installation box, and a sealing plate is slidably connected to the lower end of the placement box, and corresponding slide grooves and slide rails are arranged between the lower end of the placement box and the sealing plate, and two connecting plates I and II are arranged on the slide groove of the sealing plate, and mounting plates I and II cooperating with the two connecting plates are arranged at the lower end of the placement box, a compression spring is arranged between the connecting plate I and the mounting plate I, and a contraction spring is arranged between the connecting plate II and the mounting plate II, a hole cooperating with the placement box is arranged on the sealing plate, a slide groove is arranged at the front end of the placement box, and a baffle is slidably connected to the slide groove.

[0011] Preferably, support feet for supporting the device are provided at the lower end of the housing. At the front section of the housing, there are respectively a particulate matter treatment inspection opening, a filtration inspection opening, and a catalytic inspection opening. The particulate matter treatment inspection opening, the filtration inspection opening, and the catalytic inspection opening are respectively arranged corresponding to the particulate matter treatment mechanism, the filtration mechanism, and the catalytic mechanism inside the housing. And detachable sealing covers are correspondingly arranged on all the inspection openings. Support feet for supporting the device are also provided at the lower end of the housing.

[0012] Preferably, the catalytic mechanism includes a catalytic main frame, which is composed of two serpentine plates. An exhaust gas pipeline is formed between the two serpentine plates. The advantage of setting the serpentine plates is to increase the distance of the exhaust gas flow path and assist the ultraviolet lamp irradiation for photocatalytic oxidation. An ultraviolet lamp is provided at the bent part of the exhaust gas pipeline. An inner air inlet is provided at the upper end of the catalytic main frame, and an inner air outlet is provided at the lower end of the catalytic main frame.

[0014] The beneficial effects of the present utility model compared with the prior art are as follows:

[0015] 1) By providing a particulate matter treatment mechanism, the particulate impurities in the exhaust gas are filtered. The exhaust gas passes through the metal sintered filter plate, and the impurities in the exhaust gas are quickly cleaned. At the same time, the metal sintered filter plate can be recycled.

[0017] 3) By providing a particulate matter treatment mechanism, most of the impurities are removed, reducing the workload of the filtration mechanism. Then, cooperating with the filtration mechanism, the impurities in the exhaust gas are removed, reducing the replacement times of the filtration mechanism and increasing the service life. A sealing plate is slidably connected to the lower end of the filtration mechanism. After the placement box is pulled out, the filter holes on the sealing plate are misaligned with the filter holes on the placement box, blocking the filter holes of the placement box to prevent the activated carbon particles (such as activated carbon particles) from falling when the activated carbon is placed in the placement box and shaken. When the placement box is inserted into the installation box, the sealing plate contacts the inner wall of the housing, aligning the sealing plate with the placement box, and the filter holes on the placement box and the sealing plate are coaxially arranged to realize the function of filtering the exhaust gas.

[0034] Combined with Figure 1 As shown, the catalytic mechanism 7 includes a catalytic main frame 71 which is composed of two serpentine plates.

[0036] The working principle of a catalytic type exhaust gas comprehensive treatment and purification device is as follows:

[0037] When the device is in use, first, open the filter maintenance opening 102, manually pull the baffle 63, and the baffle 63 drives the placement box 62 and the sealing plate 64 to slide outwards. When the placement box 62 slides outwards, the sealing plate 64 cooperates with the connecting plate Ⅰ641 and the connecting plate Ⅱ642 through the compression spring and the contraction spring at the lower end, so that the filter holes on the sealing plate 64 are misaligned with the filter holes on the placement box 62. Then, add filter materials (such as activated carbon) into the placement box 62. The sealing plate 64 prevents a small amount of the filter materials from flowing out when the movable installation box 61 is installed. On the one hand, it prevents the influence on the ground hygiene and ensures the cleanliness of the working environment. On the other hand, it prevents the placement box 62 from being collided during installation, and a large amount of the filter materials falling into the inside of the housing 1, affecting the internal cleanliness. The function of the sealing plate 64 reduces the falling situation of the filter materials. Then, slide the placement box 62 and insert it into the installation box 61. The sealing plate 64 contacts the inner wall of the housing 1, and the sealing plate 64 is pushed to be flush with the installation box 61. In the equipment, the situation that the placement box 62 is collided inside is reduced, and the situation that the filter materials fall is reduced. The filter holes on the sealing plate 64, the filter holes on the placement box 62 and the filter holes on the installation box 61 are coaxial, realizing gas filtration. At the same time, a baffle 63 is slidably connected to the front end of the placement box 62, which seals the filter materials in the placement box 62 and is convenient for pulling the placement box 62;

[0038] Exhaust gas enters through the air inlet 4. The exhaust gas enters from the lower end of the partition plate Ⅰ104 to the side of the particulate matter treatment mechanism 5. When the exhaust gas moves upward from the lower end of the partition plate Ⅰ104, it passes through the lower filter plate assembly 52. When the exhaust gas contacts the metal sintered filter plate 525, large particulate impurities such as dust in the exhaust gas are filtered onto the metal sintered filter plate 525. A plurality of metal sintered filter plates 525 are arranged on the filter plate assembly 52. At the same time, the metal sintered filter plate 525 can be quickly removed and cleaned by opening the sealing door on the particulate matter treatment maintenance opening 101, so that the exhaust gas enters the filter mechanism 6 on the other side, reducing the workload of the filter mechanism 6; When the metal sintered filter plate 525 needs to be replaced later (as Figure 3 shown), open the particulate matter treatment maintenance opening 101, manually pull out the filter plate assembly 52. The filter plate assembly 52 slides out through the sliding wheels 524 arranged on both sides, and cooperates with the limiting component and the large-diameter sliding wheels 524 on the sliding groove 51, so that the sliding base 523 is obliquely placed outside the sliding groove 51. Then, manually pull the U-shaped bracket 521 to take out the metal sintered filter plate 525, put in a new metal sintered filter plate 525, and press the metal sintered filter plate with the U-shaped bracket 521 with a rubber pad arranged on one side. At the same time, by setting bolts on the U-shaped bracket 521, the distance between the U-shaped bracket 521 and the connecting plate Ⅲ522 is adjusted to cooperate with metal sintered filter plates of different thicknesses, so as to better press the metal sintered filter plate 525 between the U-shaped bracket 521 and the sliding base 523, preventing the metal sintered filter plate 525 from being misaligned when the sliding base 523 resets;

[0039] The exhaust gas passes through the particulate matter treatment mechanism 5 and the filtration mechanism 6, and finally enters the catalytic mechanism 7. The exhaust gas enters the exhaust gas pipeline 75 through the inner air inlet 74, and is irradiated by the ultraviolet lamp 73 for catalytic reaction of the exhaust gas. Then the exhaust gas passes through the exhaust gas pipeline 75 and is discharged through the inner air outlet 72, and is discharged through the air outlet 3. The flow path length of the exhaust gas pipeline 75 is increased to enable better irradiation of the ultraviolet lamp 73 with the exhaust gas for catalytic reaction.

[0040] The above content is only an example and description of the structure of the present utility model.
