Problems solved by technology

[0014] However, the photocatalyst devices of the single channel type extended surface type in the above three situations all have the following disadvantages: the air flowing in the channel will be subjected to a large flow resistance, and in the field of ventilation systems that are more sensitive to the flow resistance, such as vehicles. In ventilation systems, flow resistance requirements are likely not met
[0019] However, the photocatalyst device of the superimposed honeycomb flow channel of the above three situations also has the following disadvantages: the air flowing in the flow channel will be subject to a large flow resistance. In the field of ventilation systems that are more sensitive to flow resistance, such as the ventilation of vehicles system, it is likely that the flow resistance requirements will not be met
However, this idea has not been realized in kind, and its actual effect remains to be verified

Abstract

The invention discloses a photocatalyst honeycomb subassembly. The photocatalyst honeycomb subassembly is capable of enlarging the contact area of polluted air with photocatalysts as far as possible, ensuring sufficient light irradiation of photocatalyst surfaces is achieved as far as possible, and at the same time allowing flow resistance of air flow in flow channels to satisfy ventilation systems with relatively high requirements on flow resistance. The photocatalyst honeycomb subassembly comprises a photocatalyst honeycomb subassembly housing, and one or a plurality of photocatalyst honeycomb filter elements; each photocatalyst honeycomb filter element is composed of a plurality of filter element elementary units arranged in a honeycomb manner; the filter element elementary units are polygonal or circular from axial view; one part of the polygonal or the circular internal surface, or the whole polygonal or the circular internal surface of each filter element elementary unit is coated with a photocatalyst coating layer; and polygonal or circular air channels, used for flowing of air, are formed by encircling of the polygonal or the circular internal surfaces of the filter element elementary units.

Description

technical field [0001] The invention relates to a photocatalyst honeycomb component and a photocatalyst purification device. More specifically, the invention relates to a photocatalyst purification device which utilizes the principle of photocatalyst to purify air and the photocatalyst honeycomb component therein. Background technique [0002] Photocatalyst is a substance that does not change itself under the irradiation of light, but can promote chemical reactions. Under the irradiation of light, the photocatalyst can activate the oxygen and water adsorbed on the surface of the material, produce free hydroxyl groups and active oxygen with strong oxidizing ability, and undergo an oxidation reaction to completely decompose organic matter, bacteria, viruses, etc. into carbon dioxide and water. [0003] Photocatalyst air purification technology is an ideal technology for controlling environmental pollution in the world. Among them, the key to the excellent purification effect...
