Photocatalyst honeycomb assembly and photocatalyst purification device

Abstract

The invention discloses a photocatalyst honeycomb assembly and a photocatalyst purification device which can increase the contact area between polluted air and photocatalyst to the greatest extent, can guarantee the surface of the photocatalyst to obtain enough ultraviolet irradiation to the greatest extent, enables flow resistance suffered by air flowing in a runner to satisfy the field of ventilation systems with higher flow resistance requirement, and can largely increase the quantity of fully purified air currents. The photocatalyst honeycomb assembly comprises a photocatalyst honeycomb assembly shell and a plurality of photocatalyst honeycomb filter elements; the photocatalyst honeycomb filter elements are formed by arranging a plurality of filter element basic units in a honeycomb form; the ends of all the filter element basic units are polygonal or circular; one parts or all parts of the inner surfaces of all the filter element basic units are attached with photocatalyst coating layers; and the photocatalyst honeycomb filter elements are arranged in a butt joint manner by a mode of mutually staggering by 1 / 2 honeycomb radius, so that honeycomb air channels in the staggered surfaces among the photocatalyst honeycomb filter elements are cut to a plurality of subareas.

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...

[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
