Embodiment Construction

[0015] An air purification method: the water vapor in the purified clean air needs to be recovered by using a water vapor condensation baffle.

[0016] The porous conductive diamond film anode plate is based on a silicon wafer. First, the through-hole array is formed by wet etching, and then the high-conductivity diamond film is deposited on both sides of the silicon substrate by doping boron or nitrogen by chemical vapor deposition. The surface of the silicon wafer is completely covered by a diamond film, and through holes are left.

[0017] A positive voltage is applied to the porous conductive diamond film anode plate immersed in the electrolyte to electrolyze water, and hydroxyl radicals (OH) will be generated on the surface of the porous conductive diamond film anode plate. Hydroxyl free radicals are well-known strong oxidation active groups , the oxidation ability is second only to fluorine (see reference [1] for the generation mechanism of hydroxyl radicals). It can dir...

Abstract

The invention relates to an air purification method and an air purification device. The air purification method is to oxidize formaldehyde, benzene, and carbon monoxide dissolved or dispersed in water in the air by utilizing the strong oxidizing agent hydroxyl radical produced in the electrolyte by the porous conductive diamond film anode. Generate carbon dioxide and water, and at the same time oxidize and inactivate viruses and bacteria to achieve the purpose of purifying the air. The air purification device includes a casing (1), an electrochemical reaction vessel (2), an induced draft fan (3) and a DC power supply (4). This method is safe, efficient, broad-spectrum, and has no secondary pollution emissions. It can oxidize formaldehyde and benzene in the air to generate carbon dioxide and water, and at the same time oxidize and inactivate viruses and bacteria. The fresh air filtered by the electrolyte is passed through the gas-liquid Separate exhaust system exhaust. It has the advantages of low power consumption, low cost, and zero pollution discharge. This device has the advantages of simple structure, small size, low power consumption, long life, convenient maintenance, low cost, zero pollution discharge and the like.

Description

technical field [0001] The invention relates to an air purification method and an air purification device, in particular to a method and a device for purifying air by using a porous conductive diamond film. Background technique [0002] With the development of society, indoor air pollution has become one of the important factors that endanger human health. Indoor air pollutants mainly include: organic gas molecules such as formaldehyde and benzene released from home decoration materials, carbon monoxide and smoke particles produced by tobacco leaf combustion, and air pollution. Bacteria, viruses, etc. The existing air purification methods mainly include: physical adsorption filtration method, chemical reagent treatment method, photocatalysis method, negative ion material catalysis method. Among them, the physical adsorption filtration method mainly uses porous materials such as activated carbon as the adsorbent. Due to its low price, it is widely used at present. However, ...
