Embodiment 1
[0054] A kind of air purifier that removes indoor VOCs of the present invention, as figure 1 As shown, the purifier comprises a bottom case 23, a photocatalytic degradation unit, an ozone decomposition purification unit, a fan 15, a top case 14, an outer shell (the outer shell is made up of a front shell 1 and a rear shell 17);
[0055] Bottom shell 23 has sieve hole and is used for air to flow in and filter large particle sundry, and leg is installed under the bottom shell so that purifier and placement surface leave space.
[0056] The photocatalytic degradation unit is used for photocatalytic reaction to generate ozone to catalyze the degradation of pollutant VOCs. The photocatalytic degradation unit includes: a VUV lamp 21 fixed on the VUV lamp base 22, one VUV lamp is used in this embodiment The vacuum ultraviolet light lamp is ZW10D15Y-Z212, which can emit ultraviolet light with a wavelength of 185nm to generate ozone. A steel bracket 5 is used to support the titanium s...
Embodiment 2
[0064] On the basis of the air purifier of embodiment 1, a fan can also be installed between the bottom case and the photocatalytic degradation unit, such as Figure 5 As shown, it is possible to control the inhalation of more air that needs to be purified.
[0065] The VUV lamp number in embodiment 1 and 2 can also be 4 or 9, can reach better photocatalytic degradation VOCs effect, as Figure 4 shown. Divide the VUV lamp base 23 into 4 or 9 grids with steel brackets, install the VUV lamps in the corresponding grids, and install the titanium sheet 4 on the bracket 5, the titanium sheet is adjacent to the vacuum ultraviolet lamp, and the titanium sheet 4 is fixed through the hollow Frame and screws are fixed on the support 5.
[0066] A counterweight plate can also be installed on the outside of the fixed plate opposite to the VUV lamp circuit control device, and the weight of the counterweight plate matches the VUV lamp circuit control device to maintain balance and make the...
specific example 1
[0085] Weigh 6g of potassium permanganate, add it into 100mL of pure water, and sonicate until completely dissolved. Then add 4mL ammonia solution, stir and mix. Degrease and alkali wash the aluminum sheet with a mass of 20g to remove the grease and oxide layer on the surface, wash it with pure water until the surface is completely wet, and then put it into the above-mentioned potassium permanganate-ammonia water mixture. The solution was placed in a constant temperature water bath at 40°C for 2 h. The aluminum sheet is taken out and dried at 60° C. to obtain a pretreated aluminum sheet.
[0086]Weigh 29.44g of manganese acetate and 24.24g of ferric nitrate, add 400mL of water, and sonicate until the manganese acetate and ferric nitrate are completely dissolved. Weigh 12.64g of potassium permanganate and 2.0g of CTAB, add 400mL of water, stir the resulting solution continuously, and add a mixed solution of manganese acetate and ferric nitrate dropwise thereto. The completel...
