Referring to fig. 1, the purification apparatus includes a purification composition 10 and a light guide member 20; the purification composition 10 includes a photocatalytic material and an adsorbent material; the light guide assembly 20 is used for guiding the light generated by the light source to the photocatalytic material, so that the photocatalytic material can purify the pollutants in the environment and the pollutants adsorbed by the adsorbing material.
Another embodiment of the present application further provides an air conditioner, which includes the purification device provided in any embodiment of the present application.
The pollutants described in the embodiments of the present application mainly refer to fine particulate matters (PM2.5), Volatile Organic Compounds (VOCs), semi-volatile organic compounds (semi-SVOCs), harmful microorganisms, allergic substances, odorous gases, and the like, which are commonly found in daily environments.
The photocatalytic material is a semiconductor catalyst material capable of generating photochemical reaction under the action of light, the photocatalytic material can generate photoproduction electrons and photoproduction holes under the excitation of light, a part of the photoproduction electrons and the photoproduction holes can be compounded on the bulk phase or the surface of the photocatalytic material and disappear in the migration process, energy is released in the form of heat or photons, the other part of the photoproduction electrons or the photoproduction holes can migrate to the surface of the photocatalytic material and respectively generate reduction and oxidation reactions with a reactant, if the generated photoproduction electrons have enough reduction capacity, oxygen adsorbed on the surface of the photocatalytic material can be converted into free radicals, and similarly, if the generated photoproduction holes have enough oxidation capacity, the generated photoproduction electrons can react with adsorbed water on the surface of the photocatalytic material to generate hydroxyl free radicals, and finally the active free radicals can further perform oxidation reaction with organic matter molecules adsorbed on the surface of the photocatalytic material, thereby achieving the purification of the pollutants.
The light guide assembly 20 may enable the light generated by the light source to excite the photocatalytic material by guiding the light generated by the light source to the photocatalytic material.
The adsorbing material can adsorb the pollutants in the environment, but can not decompose the pollutants adsorbed by the adsorbing material, that is to say, the adsorbing material has saturation, and after the adsorbing material reaches adsorption saturation, the adsorbing material can not further adsorb the pollutants.
In the related art, there are air conditioners that perform purification by a photocatalytic method and air conditioners that perform purification by an adsorption method, but the air conditioners that perform purification by a photocatalytic method require a photocatalytic material to be excited by light to purify contaminants, and if the contaminants are to be purified at night, the UV (ultraviolet) mercury lamp or UV-LED lamp for exciting the photocatalytic material needs to be continuously turned on, which affects the sleep quality of consumers, in case that more than 70% of the air conditioners are used at night. And the air conditioner that adopts the adsorption mode to purify need to be changed the adsorption material after the adsorption material reaches the adsorption saturation, from this, also can influence consumer's use and experience.
