Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and specifically to an anti-clogging photo-thermal catalytic combustion waste gas dynamic purification device. Background Art

[0002] A photo-thermal catalytic combustion waste gas dynamic purification device is an environmental protection equipment that combines photocatalysis, thermal catalysis and combustion technologies for dynamic treatment of waste gas. It mainly realizes the efficient decomposition and purification of pollutants in the waste gas through the synergistic effect of photo-excited catalyst and heat energy.

[0003] Existing filter plates are difficult to continuously update the filtering surface, increasing the problem of pore blockage caused by impurity accumulation in traditional fixed filter plates. Moreover, it is difficult to make the unblocked filtering areas always participate in solid-gas separation, thus making it difficult to maintain a stable waste gas throughput, resulting in a decrease in treatment efficiency due to an increase in filtering resistance. At the same time, it is difficult to assist in separation through centrifugal force, reducing the particulate capture ability; during the use of existing filter plates, when a single piece is damaged, it is difficult to quickly replace, and it is difficult to avoid the cross-flow of waste gas between modules. At the same time, it is difficult to configure different filter materials in different fan-shaped modules, and the metal filter plate is prone to overall thermal deformation at high temperatures, resulting in the jamming of the scraper. It is difficult for the existing technology to reserve an expansion gap between fan-shaped modules to allow thermal expansion; In addition: during the use of the existing technology, it is difficult to reduce the gas flow rate, slow down the impact of the air flow on the filter plate, avoid large particles directly penetrating the filter layer due to too fast flow rate, and reduce the interception efficiency; Finally: during photo-thermal catalysis of the existing technology, it is difficult to make the light emitted by the light source irradiate the surface of the catalytic plate more vertically or evenly, increasing light reflection loss or shadow areas and reducing the utilization rate of light energy; it is difficult to keep the catalytic plate always at the best angle with the light direction to maximize the light absorption efficiency, and it is difficult to make the air flow form turbulence, reducing the residence time of the gas on the surface of the catalytic plate and reducing the mass transfer effect; when the existing catalytic plate is in use, it is difficult to make the leaked light reflect multiple times in a narrow space, reducing the contact times between the light and the catalytic plate. When using baffles in some equipment, it is difficult to adjust the distance between the baffle and the catalytic plate, increasing the phenomenon of overheating due to too strong local light intensity on the catalytic plate. At the same time, it is difficult to make the light energy more evenly distributed on the surface of the catalytic plate, increasing the sintering risk of "hot spot areas", and it is difficult to reflect visible light back to the catalytic plate, reducing the generation efficiency of photo-generated carriers.

Then, through the action of a higher temperature and the catalyst, the organic matter is completely oxidized into carbon dioxide and water, and the waste gas is dynamically treated through combustion technology; Third, when the waste gas enters the filter box 2 to remove large particulate impurities, six groups of first electromagnets 34 are driven to work step by step by an external current output device, causing the second electromagnet 35 to move up and down under the magnetic adsorption influence of the first electromagnet 34.

[0045] The third rotating block 64 is rotatably connected with the fixing frame 63. The left and right ends of the installation shell 66 are conical. The bottom of the fourth rotating block 68 is rotatably connected with the top of the installation shell 66. The front left side of the top of the fixing frame 63 is fixedly connected with the installation shell 66. The back of the electric spring 69 is fixedly connected with the inner rear end of the third installation box 61. The rotating rod 610 penetrates through the bottom of the photocatalytic combustion box 5 and is rotatably connected with its interior.

[0046] In this embodiment: When it is necessary to drive the catalytic plate 611 for angle adjustment, the second motor 62 is started. The second motor 62 drives the third rotating block 64 to rotate. The third rotating block 64 drives the spherical block 65 to slide within the mounting shell 66. The spherical block 65 drives the fourth rotating block 68 to rotate through the arc-shaped rod 67. The fourth rotating block 68 drives the rotating rod 610 to rotate. The rotating rod 610 drives the catalytic plate 611 for angle adjustment, so that the light emitted by the light source irradiates the surface of the catalytic plate 611 more vertically or evenly, reducing light reflection loss or shadow areas, improving the utilization rate of light energy. At the same time, the catalytic plate 611 always maintains the best angle with the light direction, causing the air flow to form a turbulent flow, increasing the residence time of the gas on the surface of the catalytic plate 611. And during the rotation of the fourth rotating block 68, the electric spring 69 is squeezed. During the extrusion process of the electric spring 69, a stress field is generated around it. This stress field will affect the resistance value of the resistance strain gauge 613. Then, the resistance strain element inside the resistance strain gauge 613 deforms under the action of stress, enabling the staff to calculate the length change of the electric spring 69 through the resistance value of the resistance strain gauge 613, and calculate the rotation angle of the catalytic plate 611 through the length change of the electric spring 69.

[0047] Embodiment Five:

[0048] Please refer to Figure 9 , an anti-clogging photothermal catalytic combustion waste gas dynamic purification device of the present invention. Compared with Embodiment One, this embodiment further includes: a baffle mechanism 612. The baffle mechanism 612 includes a mounting rod 6121. Both the front and rear sides of the left end of the catalytic plate 611 are fixedly connected with the mounting rod 6121, which facilitates the installation and fixation of the mounting rod 6121 on the catalytic plate 611.

[0049] Four groups of fourth electromagnetic blocks 6122 are fixedly connected inside the mounting rod 6121, and the fourth electromagnetic blocks 6122 are electrically connected to an external current output device. The fourth electromagnetic blocks 6122 are magnetically adsorbed to the fifth electromagnetic blocks 6123, and the fifth electromagnetic blocks 6123 are electrically connected to an external current output device. The fourth electromagnetic blocks 6122 facilitate driving the fifth electromagnetic blocks 6123 to move.

[0050] A baffle 6124 is magnetically adsorbed to the left end of the fifth electromagnetic block 6123. A titanium dioxide coating 6125 is sprayed on the right end of the baffle 6124. The fifth electromagnetic block 6123 penetrates the left end of the mounting rod 6121 and is slidably connected to its interior.

[0051] In this embodiment: When the baffle 6124 needs to be used, an external current output device drives the four groups of fourth electromagnetic blocks 6122 and fifth electromagnetic blocks 6123 to work, causing the fifth electromagnetic block 6123 to move left and right under the magnetic adsorption influence of the four groups of fourth electromagnetic blocks 6122. The fifth electromagnetic block 6123 drives the baffle 6124 to move left and right, adjusting the distance between the baffle 6124 and the catalytic plate 611. The baffle 6124 causes the leaked light to be reflected multiple times in a narrow space, increasing the contact times between the light and the catalytic plate 611. At the same time, through distance adjustment, it avoids overheating caused by excessive local light intensity on the catalytic plate 611, making it more evenly distributed on the surface of the catalytic plate 611, reducing the sintering risk of the "hot spot area", and reflecting the visible light back to the catalytic plate 611 through the titanium dioxide coating 6125, improving the generation efficiency of photo-generated carriers.

[0052] The present invention provides an anti-blocking photo-thermal catalytic combustion waste gas dynamic purification device through improvement. The anti-blocking mechanism 3 is set up. By driving the filtering mechanism 39 to rotate, the two scrapers on its right side continuously update the filtering surface, reducing the pore blockage problem caused by impurity accumulation in the traditional fixed filtering mechanism 39, enabling the unblocked filtering area to always participate in solid-gas separation, maintaining a stable waste gas throughput, preventing the decline in treatment efficiency caused by an increase in filtering resistance, and at the same time, using the centrifugal force generated by the rotation of the filtering mechanism 39 to assist in separation, improving the particulate capture ability; the filtering mechanism 39 is set up. The sealing layer 394 is used to prevent the waste gas from flowing through between the first filter plates 396. At the same time, through the magnetic adsorption and non-magnetic adsorption states of the third electromagnetic block 393 and the slot 392, when a single first filter plate 396 is damaged, it can be quickly replaced, and different first filter plates 396 are configured according to different needs. Then, the airbag 395 reserves an expansion gap for the first filter plate 396 to allow its thermal expansion; the control and adjustment mechanism 4 is set up. By driving the valve plate inside the air valve 415 to move, the opening degree of the air valve 415 is adjusted, reducing the gas flow rate, slowing down the impact of the air flow on the second filter plate 8, preventing large particles from directly penetrating the second filter plate 8 due to excessive flow rate, and improving the interception efficiency; the adjustment mechanism 6 is set up. By adjusting the angle of the catalytic plate 611, the light emitted by the light source can irradiate the surface of the catalytic plate 611 more vertically or evenly, reducing light reflection loss or shadow areas, improving the utilization rate of light energy, and at the same time, keeping the catalytic plate 611 at the best angle with the light direction all the time, causing the air flow to form turbulence and increasing the residence time of the gas on the surface of the catalytic plate 611; the baffle mechanism 612 is set up. The baffle 6124 causes the leaked light to be reflected multiple times in a narrow space. At the same time, through distance adjustment, it avoids overheating caused by excessive local light intensity on the catalytic plate 611, reducing the sintering risk of the "hot spot area", and reflecting the visible light back to the catalytic plate 611 through the titanium dioxide coating 6125, improving the generation efficiency of photo-generated carriers.
