Embodiment Construction
[0023] The invention provides an air cleaning device, which comprises a photocatalyst channel arranged in a fixed casing (101, 201) and an ultraviolet lamp (103, 203) arranged in a space surrounded by the photocatalyst channel.
[0024] The photocatalyst channel is a porous channel, which can be a honeycomb structure, such as figure 1 shown, or a network structure such as figure 2 shown. The surface of the porous channel is used as a carrier to coat the photocatalyst, and the photocatalyst can also be embedded in the wall of the porous channel or arranged in other ways.
[0025] The photocatalyst passage includes a front passage and a rear passage, and the wind resistance of the front passage is smaller than that of the rear passage. like figure 1 The wind resistance of the front honeycomb channel 104 in the middle is less than the wind resistance of the rear honeycomb channel 102; figure 2 The wind resistance of the front grid channel 204 is smaller than the wind resist...

The invention provides an air purification device. The air purification device comprises a photocatalyst channel arranged in a shell which plays a fixing role and an ultraviolet emitting device arranged in a space surrounded by the photocatalyst channel. A fan drives the air in the space and sucks the air into the air purification device; firstly, the air is catalyzed through the photocatalyst channel, then, the air is subjected to photo-catalytic oxidation through the ultraviolet emitting device, and the air is catalyzed again through the photocatalyst channel at the other side of the ultraviolet emitting device, finally, the air returns back to the space. The air purification device has comprehensive purification functions and has an ideal decomposition effect on most harmful substances and organic peculiar smells; the air purification device can completely decompose the pollutant and can decompose the pollutant into pollution-free reaction products through a chain reaction; the air purification device actively purifies the air and actively captures the harmful substances in the indoor air to purify the air; and the air purification device is small in size, light in weight, convenient to assemble and disassemble, firm and durable in structure, low in noise and long in service life.
Description
technical field [0001] The invention relates to the field of air purification devices, and in particular introduces a catalytic oxidation device for purifying air and a purification method thereof. Background technique [0002] At present, the air purifiers that are common on the market and are more suitable for home use can be roughly divided into the following three types. [0003] Filter type: This kind of air purifier usually uses activated carbon as the filter material, through which the activated carbon filters out harmful substances such as benzene and formaldehyde in the air to achieve the purpose of purifying the indoor air. However, since the ability of activated carbon to absorb harmful substances will gradually weaken after being used for a period of time, the filter element should be replaced every once in a while (about 3 months is recommended for heavily polluted areas). [0004] Electrostatic air purifier: An air purifier that concentrates the dust in the ai...
