Description

Technical Field

[0001] The utility model relates to the technical field of ozone decomposition, in particular to a device for rapid decomposition of ozone. Background Art

[0002] Ozone is a strong oxidant. When the ozone concentration in the indoor environment is too high, purification treatment is required. The purification of ozone usually adopts the decomposition method. Among them, the catalytic decomposition method is the most widely used. The ozone decomposition methods at home and abroad include activated carbon method, thermal decomposition method, electromagnetic wave radiation decomposition method, liquid medicine absorption method and catalytic decomposition method.

[0003] The existing ozone decomposition device for ozone sterilization and disinfection generally cooperates with each other through a shell, an air inlet, an air outlet, a driving fan, an ultraviolet photolysis area and a catalytic oxidation area. Driven by the driving fan, the ozone-containing air enters from the air inlet, undergoes ultraviolet photolysis and catalytic oxidation degradation by the catalyst, and finally passes through an ozone detection device to measure the ozone concentration at the outlet, and then is discharged from the air outlet.

[0004] However, when the above-mentioned existing technology decomposes ozone, the electromagnetic wave radiation decomposition method can be used to decompose ozone by ultraviolet lamps. However, the moving speed of ozone in the shell is relatively fast, so the contact time with ultraviolet rays is relatively short, which will affect the decomposition efficiency. And it is not convenient to replace the catalyst after it fails, which further affects the decomposition efficiency of ozone. Content of the Utility Model

[0068] Refer to Figure 3 And Figure 4, the installation mechanism includes a second cavity, a limiting groove 14, a limiting block 15 and a relative movement mechanism. There are two second cavities formed in the installation block 3. Limiting ports are provided on two opposite side walls of the second cavity.

[0070] In this embodiment, during use, after the operator passes ozone into the decomposition tank 1 through the air inlet pipe 2, the ozone passing through the fixing port 5 can be irradiated by the ultraviolet rays emitted by the ultraviolet lamp tube 6, so as to decompose the ozone. At the same time, through the wind deflector 7 and the staggered first air vents, the time for ozone to pass through the fixing port 5 can be extended, thereby improving the decomposition effect of ozone. Then, the ozone can be further catalyzed by the catalytic filter plate 9 in the catalytic housing 8, so as to improve the catalytic efficiency of ozone. When the ultraviolet lamp tube 6 is damaged, the operator rotates the second handwheel 21. The rotation of the second handwheel 21 can drive the adjusting rod 17 and the second bevel gear to rotate. At the same time, through the meshing of the second bevel gear and the first bevel gear, the first bevel gear and the worm 20 are driven to rotate. Furthermore, through the meshing of the worm 20 and the worm gear 19, the worm gear 19 and the adjusting disk 16 are driven to rotate.
