Description

Technical Field

[0001] This utility model relates to the field of coating production technology, and in particular to a UV photodecomposition device for coating production waste gas. Background Technology

[0002] Paint production refers to the process of processing various raw materials into paint products through specific processes and equipment. Paint is a material that is coated on the surface of an object to form a continuous film, providing protection, decoration, and special functions (such as corrosion prevention, fireproofing, and insulation). A UV photodecomposition device for paint production waste gas is an environmentally friendly device that uses ultraviolet photodecomposition technology to treat paint production waste gas.

[0003] In existing technologies, paint production waste gas often contains non-gaseous pollutants such as dust and paint particles. If the UV photodecomposition device cannot effectively clean and remove these particles, the particles may adhere to the surface of the UV lamp tube, reducing the light transmittance of the lamp tube and thus affecting the emission of ultraviolet rays and the efficiency of the photodecomposition reaction. This results in poor decomposition of organic pollutants and makes it difficult to achieve the desired purification effect. The accumulation of particles in the equipment can even cause safety accidents such as short circuits. Moreover, some particles in paint production waste gas may have flammable and explosive properties. If they are not removed in time, the risk of fire or explosion increases. If the particles cannot be effectively removed, they may be emitted into the atmosphere with the treated waste gas, causing secondary pollution and adversely affecting environmental quality. In addition, byproducts such as ozone may be generated during the UV photodecomposition process. If the particles in the waste gas react with ozone, other harmful substances may be generated. Therefore, it is necessary to improve the UV photodecomposition device for paint production waste gas to solve the above problems. Utility Model Content

[0004] In order to overcome the problem that the UV photodecomposition device for paint production waste gas cannot effectively treat particulate matter in the waste gas, thus failing to achieve the desired purification effect, increasing the risk of fire or explosion and generating other harmful substances.

[0013] The beneficial effects of this utility model are:

[0014] 1. Compared to the UV photodecomposition device for paint production waste gas, which cannot effectively treat particulate matter in exhaust gas, this device, through a threaded connection between a rotating threaded rod and a sliding connecting seat, allows the sliding connecting seat to slide inside the mounting box. The sliding connecting seat then drives a cleaning brush to clean the dust-proof plate, ensuring the light transmittance of the lamps, the efficiency of ultraviolet emission and photodecomposition reaction, and the decomposition effect of organic pollutants. This achieves ideal purification results, prevents equipment malfunctions, reduces the risk of fire or explosion, effectively removes particulate matter, and prevents the generation of harmful substances.

[0015] 2. The sealing cover is removed by disassembling the connecting latches, and then the activated carbon filter and titanium dioxide-aluminum-based honeycomb photocatalyst, which are snapped together inside the filter slot and photocatalyst slot, are pulled out to achieve disassembly. Paint production waste gas typically contains a large amount of particulate matter, paint mist, and volatile organic compounds (VOCs). During UV photodecomposition, these pollutants may adhere to the purification components, such as UV lamps and photocatalytic plates. The detachable purification components allow operators to easily remove these components from the equipment for thorough cleaning, removing surface contaminants and ensuring normal component performance. Operators can quickly disassemble the lamps for inspection to determine whether the problem is lamp aging, damage, or a circuit issue, and replace or repair them promptly, reducing equipment downtime and improving production efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a UV photodecomposition device for paint production waste gas, including a photodecomposition device body 1, a support base 2 fixedly connected to the bottom of the photodecomposition device body 1, an exhaust pipe 3 fixedly connected to one side of the photodecomposition device body 1, an installation connection box 5 fixedly connected to one side of the photodecomposition device body 1, a wastewater storage box 4 fixedly connected to the bottom of the installation connection box 5, a purification component disposed inside the photodecomposition device body 1, a dustproof plate 901 disposed on the installation connection box 5, a first motor 902 fixedly connected to the installation connection box 5, a rotating threaded rod 903 fixedly connected to the output end of the first motor 902, a fixing column 904 fixedly connected inside the installation connection box 5, a sliding connection seat 905 threadedly connected to the rotating threaded rod 903, and a rotatably connected to the sliding connection seat 905. The cleaning brush 906 on the 05 unit discharges the purified gas from the main body 1 of the photodecomposition device through the air outlet pipe 3. The wastewater storage box 4 is used to store wastewater. The threaded rod 903 is threadedly connected to the sliding connecting seat 905. The rotation of the threaded rod 903 drives the sliding connecting seat 905 to slide inside the mounting box 5. When there are stains on the dustproof plate 901, the first motor 902 drives the threaded rod 903 to rotate inside the mounting box 5. The threaded rod 903 is threadedly connected to the sliding connecting seat 905, which drives the sliding connecting seat 905 to slide inside the mounting box 5. The sliding of the sliding connecting seat 905 drives the cleaning brush 906 to contact the dustproof plate 901 and scrape off the dust particles on the dustproof plate 901.

[0024] Please see Figure 4 -- Figure 5In this embodiment, the mounting connection box 5 has a groove at the corresponding position of the sliding connection seat 905. The sliding connection seat 905 slides inside the groove. By opening the groove inside the mounting connection box 5 at the position corresponding to the sliding connection seat 905, the sliding connection seat 905 is more stable when sliding inside the groove. Several cleaning brushes 906 are provided, and the several cleaning brushes 906 are evenly rotated and connected inside the sliding connection seat 905. The multiple cleaning brushes 906 make it more effective to clean the dustproof plate 901. An air blowing device 907 is provided on one side of the mounting connection box 5. A second motor 908 is fixedly connected to one side of the mounting connection box 5. The output end of the second motor 908 is fixedly connected to a first rotating shaft 909. A rotating seat 910 is fixedly connected to the first rotating shaft 909. The mounting connection box 5 is provided with A water storage box 911 has a third motor 912 fixedly connected to one side of the mounting connection box 5. The output end of the third motor 912 is fixedly connected to a second rotating shaft 913. An adjusting seat 914 is fixedly connected to the second rotating shaft 913. A cleaning nozzle 915 is provided on the adjusting seat 914. A connecting water pipe 916 is fixedly connected between the cleaning nozzle 915 and the water storage box 911. Cleaning water is input to the cleaning nozzle 915 through the water storage box 911 and the connecting water pipe 916. The cleaning water is sprayed onto the dustproof plate 901 through the cleaning nozzle 915 to clean the dustproof plate 901. Several cleaning nozzles 915 are provided and are evenly fixedly connected to the adjusting seat 914. The multiple cleaning nozzles 915 make the cleaning of the dustproof plate 901 more effective.

[0025] Please see Figure 2 one Figure 3In this embodiment, the purification component includes a sealing cover 801 disposed on the front of the photodecomposition device body 1, a connecting latch 802 disposed between the sealing cover 801 and the photodecomposition device body 1, a filter screen groove 803 disposed inside the photodecomposition device body 1, an activated carbon filter 804 snapped into the filter screen groove 803, a photocatalyst mesh groove 805 disposed inside the photodecomposition device body 1, a titanium dioxide aluminum-based honeycomb photocatalyst 806 snapped into the photocatalyst mesh groove 805, an electronic ballast 807 disposed on the top of the photodecomposition device body 1, a connector 808 disposed on the top of the photodecomposition device body 1, and an ultraviolet light column 809 disposed on the connector 808. The sealing cover 801 is disassembled by the connecting latch 802, and the activated carbon filter 804 and the titanium dioxide aluminum-based honeycomb photocatalyst 806 are connected by the connecting latch 802. 6. Disassembly is achieved by detaching the filter screen 803 from the photocatalyst screen 805. The activated carbon filter 804 filters the exhaust gas, the ultraviolet light column 809 cleans the exhaust gas, and the titanium dioxide aluminum-based honeycomb photocatalyst 806 converts the exhaust gas into carbon dioxide and water. Several ultraviolet light columns 809 are evenly distributed inside the photodecomposition device body 1, making the decomposition of exhaust gas more uniform. Four connecting latches 802 are evenly and symmetrically distributed between the sealing cover 801 and the photodecomposition device body 1, making the fixing of the sealing cover 801 more stable.

[0026] During operation, the activated carbon filter 804 filters the exhaust gas, the ultraviolet light column 809 cleans the exhaust gas, and the titanium dioxide-aluminum-based honeycomb photocatalyst 806 converts the exhaust gas into carbon dioxide and water. Disassembly of the purification component involves removing the sealing cover 801 via the connecting latch 802, and separating the activated carbon filter 804 and the titanium dioxide-aluminum-based honeycomb photocatalyst 806 from the filter slot 803 and photocatalyst slot 805. When dirt adheres to the dustproof plate 901, the first motor 902 drives the rotating threaded rod 903 to rotate inside the mounting box 5. When the sliding connecting seat 905 is threadedly connected to the sliding connecting seat 905, the sliding connecting seat 905 is driven to slide inside the mounting connecting box 5. The sliding of the sliding connecting seat 905 drives the cleaning brush 906 to contact the dustproof plate 901, scraping off the dust particles on the dustproof plate 901. The cleaning water is introduced into the cleaning nozzle 915 through the set water storage box 911 and the set connecting water pipe 916. The cleaning water is sprayed onto the dustproof plate 901 through the set cleaning nozzle 915 to clean the dustproof plate 901. The set blowing device 907 cooperates with the rotating seat 910 to suck in the particles that have entered the dustproof plate 901. The set second motor 908 drives the first rotating shaft 909 to drive the rotating seat 910 to rotate, so that the particles on the dustproof plate 901 are sucked in evenly.

[0027] Through the above steps, with the set rotating threaded rod 903 threadedly connected to the sliding connecting seat 905, the rotation of the set rotating threaded rod 903 drives the sliding connecting seat 905 to slide inside the mounting box 5. The sliding connecting seat 905 drives the cleaning brush 906 to clean the dust separation plate 901. This solves the problem that the UV photodecomposition device for paint production exhaust gas cannot effectively treat the particulate matter in the exhaust gas, which makes it difficult to achieve the ideal purification effect, increases the risk of fire or explosion and generates other harmful substances.
