Description

Photocatalysis coating device
Technical Field
The invention relates to a photocatalytic coating device, in particular to a photocatalytic coating device which is characterized by comprising the following components in parts by weight: a spray photocatalytic material for decomposing a substance adsorbed on the surface by a chemical reaction based on an oxidized substance generated when ultraviolet rays are irradiated to a road structure such as a street lamp, a guardrail light shielding film, a light shielding plate, a light shielding wall, a road guardrail, an inclined surface reinforcing guardrail or a concrete structure such as various buildings; the film is coated by heating to stabilize the film, so that the air pollution substance and the tiny dust are removed by photocatalysis to purify the air pollution.
Background
In general, air pollution is environmental pollution of air caused by human activities, and smoke generated in facilities such as large-scale chemical plants and thermal power plants contains carcinogenic substances and substances that directly damage lungs and heart, thereby causing pollution harmful to human bodies.
Thus, when toxic substances at the initial stage of air pollution enter the human body and accumulate, symptoms occur after years or decades, which results in insufficient understanding of air pollution. However, with the large-scale human body injury caused by the haze phenomenon, the installation of facilities for reducing air pollution is being legalized, and factories near cities are migrated on a large scale to improve the air quality and enhance the supervision through frequent detection of the air quality.
Although haze causing a large-scale human body injury is reduced, as the society develops, automobile exhaust gas generated due to the increase of automobiles becomes a main cause of air pollution, and as air flows, a problem of harm caused by pollutants flowed in korea domestically or even abroad is becoming more serious.
In particular, the world health organization WHO has specified micronic dust as a primary carcinogen. Every year, 40 million people in Europe and 62 million people in India have earlier lives because of dust \27538inadvance. Dust is one of the factors causing important problems all over the world, for example, over 600 million people die each year, 92% of all over the world is affected by dust, and the like.
The dust particles are composed of 28% of nitrogen oxide, 7% of volatile organic compound, 37% of sulfur oxide and 28% of 1-time dust particles.
Nitrogen oxides (NOx) are produced at best in the process of burning fossil fuels, mainly by: the concentration of light oil or exhaust gas from old automobiles and factory chimneys is highest, and the amount of organic solvents and road mobile pollution sources generated in coating facilities, cleaning facilities, laundry facilities, road paving, and the like is increasing in view of the current situation of Volatile Organic Compounds (VOCs) emission.
In order to remove the fine dust, fine dust reducing facilities such as artificial rainfall, spraying of washing water, etc. have been operated, but their effects are very small. Therefore, a method of reducing the cause itself of the generation of the pollutants, such as suppression of old vehicles, is being applied as a method of suppressing air pollution.
In view of the above, there is a strong need for the development of a method for effectively removing fine dusts in the form of a coating material by a chemical reaction on road facilities or various buildings for running vehicles.
