Description

Technical Field

[0001] This utility model relates to the technical field of oil fume purification devices, specifically an environmentally friendly purification-type photolysis oil fume purification device. Background Technology

[0002] Industrial waste gas and oil fumes, which often have irritating odors, are frequently generated in places such as oil refineries, chemical plants, rubber factories, restaurant kitchens, and garbage transfer stations. Therefore, purifiers are needed to purify these waste gases or oil fumes. The photocatalytic oil fume purification system uses the "photocatalytic oxidation" principle, which combines physical and chemical methods, to completely decompose oils and change their form. After purification, there are no residual oil components. The decomposition of oils can also play a role in fire prevention, sterilization, and odor elimination, without producing other pollutants, making the purification of oil fumes more environmentally friendly.

[0003] Chinese patent CN216878663U discloses an environmentally friendly photocatalytic oil fume purification device. The device includes a housing with photocatalytic lamps evenly installed inside. The input end of each lamp is electrically connected to the output end of an external power supply. An air inlet hood is bolted to one end of the housing. This invention incorporates a rotating gear, a rotating ring, a belt, a rotating plate, a baffle, a drive gear, and a motor. The motor drives the drive gear, rotating gear, rotating ring, and belt to rotate, which in turn drives the rotating plate. After entering the housing, the oil fume is rotated by the rotating plate, causing it to rotate outside the photocatalytic lamps, facilitating rapid decomposition. The baffle between the lamps blocks and guides the oil fume, increasing its travel distance and residence time within the housing. This allows the oil fume to fully contact and decompose with the ultraviolet light emitted by the lamps, resulting in higher photocatalytic efficiency.

[0004] This device increases the distance and residence time of the oil fumes within the casing, allowing them to fully contact and decompose with the ultraviolet light emitted by the photolysis lamp, resulting in higher photolysis efficiency. However, this purifier has certain requirements regarding the temperature and humidity of the oil fume gas, and its applicability to these conditions is not high, leading to low processing efficiency. Therefore, there is a need to provide an environmentally friendly photolysis oil fume purification device. Utility Model Content

[0026] Furthermore, in this embodiment, the flow equalization net 702 can block larger oil droplets and other larger impurities in the fumes, and allow them to flow into the oil guide groove under the action of gravity. Then, they flow into the oil collection groove through the through hole, preventing oil droplets from contaminating the high-frequency ultraviolet lamp tube 706 and the low-frequency ultraviolet lamp tube 712.

Example

[0027] See Figures 1-5 Furthermore, based on Embodiment 1, the oxidation section includes a second fixing seat 711, the bottom surface of which is fixedly connected to the inner wall of the housing 1, and a low-frequency ultraviolet lamp 712 is provided on the top surface of the second fixing seat 711, with the top surface of the second fixing seat 711 fixedly connected to the bottom surface of the low-frequency ultraviolet lamp 712; a second mounting frame 707 is provided between the fixing seat 705 and the second fixing seat 711, the surface of the second mounting frame 707 is slidably connected to the inner wall of the housing 1, and a catalyst mesh 708 is provided on the inner wall of the second mounting frame 707.

[0028] Furthermore, the purification device in this embodiment has low requirements for the temperature and humidity of the oil fume gas, requires no pretreatment, has a wide range of applications, and can deodorize and decompose the oil fume through the ultraviolet light generated by the high-frequency ultraviolet lamp 706 and the low-frequency ultraviolet lamp 712, thereby improving the purification efficiency of the device and extending its service life. By pulling the first handle 703 and the second handle 709 respectively, the first mounting frame 701 or the second mounting frame 707 can be pulled out respectively, so that the first mounting frame 701 or the second mounting frame 707 can slide out of the housing 1 under the sliding action of the first limiting slider 704 and the second limiting slider 710, thereby making it easier to maintain or replace the flow equalization net 702 or the catalytic net 708, and improving the practicality of the purification device.

[0029] In actual operation, the air inlet pipe 5 is first connected to the external pipeline using a flange, allowing the fumes to enter the housing 1 through the air outlet of the fan 4 under the action of the fan 4.

Then the fumes enter the photolysis chamber located at the high-frequency ultraviolet lamp 706. The high-frequency ultraviolet light emitted by the high-frequency ultraviolet lamp 706 can degrade the organic matter in the fumes into carbon dioxide and water. The catalyst coating on the catalytic net 708 can accelerate the degradation rate. The preliminarily purified fumes enter the oxidation reaction chamber through the catalytic net 708, and then... The low-frequency ultraviolet light emitted by the low-frequency ultraviolet lamp 712 reacts with oxygen to produce ozone. Ozone can remove the irritating odor from the oil fumes. After treatment, the oil fumes are further purified by the activated carbon plate 713 and then discharged into the air through the exhaust pipe. The discharged oil fume gas is environmentally friendly and pollution-free. Finally, the oil in the oil collection tank can be discharged through the oil drain pipe 714 by controlling the valve 715. When it is necessary to maintain or replace the flow equalization net 702 and the catalytic net 708, the handle 1 703 and the handle 2 709 are pulled respectively, so that the mounting frame 1 701 or the mounting frame 2 707 can be pulled out respectively. This allows the mounting frame 1 701 or the mounting frame 2 707 to slide out of the housing 1 under the sliding action of the limiting slider 1 704 and the limiting slider 2 710, making it easier to maintain or replace the flow equalization net 702 or the catalytic net 708.
