Centrifugal air purifier

Abstract

According to the centrifugal air purifier, a cylindrical inner cavity is formed in a shell, an air inlet is formed in one end of the cylindrical inner cavity, an air outlet is formed in the other end of the cylindrical inner cavity, a centrifugal fan is arranged in the cylindrical inner cavity, the air inlet side of the centrifugal fan is right opposite to the air inlet, and the air outlet side of the centrifugal fan is distributed on the peripheral wall of the centrifugal fan; the air outlet side corresponds to the inner peripheral wall of the cylindrical inner cavity; the photocatalyst carrier is arranged on the surface of the inner wall of the barrel-shaped inner cavity, and the ultraviolet light source is arranged in the barrel-shaped inner cavity and used for irradiating the photocatalyst carrier. By means of the centrifugal fan and the cylindrical inner cavity, air rotates at a high speed to generate centrifugal force, pollutants carried in the air are compressed on the surface of the photocatalyst carrier on the inner wall of the device, and the decomposition and disinfection efficiency can be improved; under the action of frictional resistance of the surface of the photocatalyst carrier, a continuous rolling forward vortex is generated, so that more gaseous pollutants can be captured by the photocatalyst, and the purification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to a centrifugal air purifier. Background technique [0002] In air purifiers, photocatalyst catalytic decomposition is a common technology to remove harmful chemical gaseous pollutants in the air. The principle is that under the irradiation of light, the surface of the photocatalyst produces pairs of holes and electrons. When water molecules in the air contact it, hydroxyl radicals are rapidly generated and attached to the surface. As a strong oxidant, this substance can decompose harmful chemical gaseous pollutants in the air. The reaction produces harmless water and carbon dioxide. Hydroxyl free radicals can also coagulate viral proteins and destroy bacterial cell walls, thereby purifying the air. This kind of purifier device usually attaches the photocatalyst carrier to the surface of a certain substrate. During operation, the air must fully contact the photocatalyst car...
