Abstract

The invention discloses a photo-catalytic air purifier of nanometer TiO2, which comprises the following parts: case, fan and purifying core, wherein the inlet and outlet are opened on the case; the purifying core is set in the case between inlet and outlet, which is cylinder-shaped porous ceramics with TiO2 in the ceramics; the fan is set in the inlet of case; the ultraviolet light source is set on the axial line of cylinder-shaped porous ceramics, which uniforms the ultraviolet strength. The invention avoids the generation of dead angle, which enlarges the touching area of air and nanometer TiO2 to strengthen the optical catalytic reaction.

Description

technical field [0001] The invention relates to a purification device for removing organic pollutants in the air in closed spaces such as indoors and cars, in particular to a purification device using nano-TiO 2 A photocatalyst air purifier that purifies the air. Background technique [0002] People spend most of their life indoors. With the improvement of living standards, the dependence on means of transportation also increases, and the time in the car also increases. Scientists have found through research that a variety of bacteria, molds, and insects grow in air conditioners and carpets, attaching to dust particles and spreading diseases through the air; paints, coatings, plywood, and harmful chemical fibers for interior decoration continue to emit formaldehyde , benzene and other toxic and harmful organic gases and carcinogens; the harmful substances produced by the human body itself and the ammonia smell of the bathroom and toilet pollute the air in the closed space. ...
