Problems solved by technology

First, the specific surface area of ​​ordinary stainless steel photocatalytic mesh is small, the amount of photocatalyst loaded is small, and the ability to capture, adsorb and purify air pollutants is poor
Second, use H 2 o 2 As an electron acceptor, it is a pure chemical method, with the use of H in the purification solution 2 o 2 Quantity changes, the stability of the effect is poor, and the cost is high
At the same time, the H entering the gas stream 2 o 2 It will cause corrosion damage to the metal parts in the downstream air flow channel, that is, produce secondary pollution, which is not conducive to long-term use

Abstract

The invention relates to a magnetization-enhanced and photocatalysis wind wheel and an air purification method; the wind wheel is characterized in that: at least two framework disks are arranged on a shaft sleeve which is sleeved outside a wheel axle, a plurality of frameworks radially and evenly distributed in the same number (not less than four) are arranged on each frame disk, a magnetization-enhanced catalysis unit is arranged between two corresponding frameworks on the adjacent framework disks, and a non-magnetically permeable fixed net is arranged at the periphery of each magnetization-enhanced catalysis unit. The air purification method adopting the magnetization-enhanced and photocatalysis wind wheel comprises the following steps: filtering, adsorbing and purifying the air pollutants from the pipeline airflow; transferring, collecting and further purifying the pollutants stuck on the magnetic permeable photocatalysis foamed metal. The magnetization-enhanced and photocatalysis wind wheel has the advantages of simple structure, small air resistance, and low operation costs; while in use, the electronic acceptors like H2O2 are not required to add into the water, and the wind wheel can still work stably and produce no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a magnetically reinforced photocatalytic wind wheel for air purification and an air purification method thereof. Background technique [0002] The harmfulness of air pollution has been recognized by the whole society, and nano-photocatalysis is considered to be one of the most promising air pollutant purification technologies due to its series of excellent characteristics. However, the main problem at present is that the prepared nano-photocatalyst is very easy to recombine photogenerated electrons and holes naturally during use, resulting in a very low photocatalytic quantum efficiency, which affects its industrial application. In the use of nano-photocatalysts, it has become a very necessary research topic to effectively separate photogenerated electrons-holes, reduce natural recombination, and improve their photocatalytic quantum efficiency by physical or ...
