Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and typical embodiments.

[0027] The method for purifying indoor air of the present invention is to first select nano-scale photocatalyst, formaldehyde and benzene capture agent and nano-scale inorganic silica gel to configure air purification treatment liquid; Atomization; then, the atomized photocatalyst-containing air purification treatment liquid is sprayed and distributed to the polluted space under the action of the fan; the ultraviolet radiation device is activated to activate the photocatalyst catalyst dispersed in the polluted space by ultraviolet light of a specific wavelength Water and oxygen in the air generate a large number of hydroxyl radicals and negative oxygen ions, and these highly oxidizing hydroxyl radicals and negative oxygen ions react with organic pollutants in the air to form water and carbon dioxide, thereby purifying indoor air.

Abstract

The invention relates to an indoor air purifying method and device, which comprises the following steps: adapting air purifying disposing liquid within photocatalytic agent; atomizing the disposing liquid into tiny particle mist material; spreading the mist disposing liquid into the polluted space through fan; activating the photocatalytic agent to catalyze the water and oxygen in the air into large amount of oxyhydrogen free radical and negative oxygen-ion. The device contains box, fan, operation panel, electric control pod, ultraviolet radiation lamp and ultrasonic atomizing device, wherein the electric control component is composed of power control mode, atomizing strength control mode and atomizing time control mode. The invention can finish air purifying disposal in a short time, which sustains the air purifying function for a long time.

Description

technical field [0001] The invention relates to the field of disinfection and purification, in particular to an indoor air purification method and device using a photocatalyst. Background technique [0002] Photocatalyst is a kind of photocatalyst whose main component is titanium dioxide. When titanium dioxide is irradiated by light, the electrons on Ti atoms are excited by light to form electron holes, so that the oxygen and water molecules adsorbed on its surface are excited to become very active. Hydroxyl free radicals and negative oxygen ions, these hydroxyl free radicals and negative oxygen ions can decompose almost all organic substances and some inorganic substances that are harmful to the human body or the environment. The above-mentioned photocatalytic reaction is carried out around the activated titanium dioxide particles, so how to increase the specific surface area of ​​the titanium dioxide particles in contact with air and pollutants is the key to determining th...
