[0001] Apparatus of reducing fine dust using photocatalysts nano particle with solar energy and operating method thereof

The present invention relates to a system for removing fine dust using solar energy and a nanoparticle photocatalyst, and a method for operating the same. Since the nanoparticle photocatalyst is activated by sunlight, it is environmentally friendly to remove fine dust and pollutants in the atmosphere and is made in the shape of a tree to complement the surrounding aesthetics. it's about

In general, in areas close to roadsides or industrial complexes, if the surrounding environment or facilities supplying fresh and clean air are insufficient, the turbid air causes great inconvenience to life and health. In addition, in the season when the yellow dust blows with the periodic drying, various diseases including the respiratory system occur frequently due to fine dust.

Meanwhile, a photocatalyst is a combination of photochemistry and a catalyst, and refers to a catalyst that exhibits activity by light energy. In general, a catalyst serves to speed up or slow down the rate of a chemical reaction without changing the catalyst itself. In the process of a chemical reaction, heat or other energy sources are used. In the case of a photocatalyst, it is the energy used in the chemical reaction. use light When light energy from sunlight or artificial light is irradiated to the catalyst, the catalyst that absorbs the light energy is activated and plays a role in oxidizing or reducing organic matter.

When a photocatalyst function exists, it is absolutely necessary to absorb light energy. Titanium oxide or titanium dioxide (TiO2), which is a widely used conventional photocatalyst, can absorb ultraviolet rays with a wavelength of about 380 nm or less. Such a photocatalytic reaction of titanium oxide takes place only when ultraviolet rays are irradiated, as much as the amount of light of ultraviolet rays.

In the following description, titanium oxide and titanium dioxide have the same meaning and are used selectively as appropriate for the context.

Titanium oxide is widely used as a white pigment, high-frequency capacitor material, optical material such as low-reflection coating, sensor and protective material, etc. In particular, it has been actively studied as a new environment-improving photocatalyst material with infinite application potential. is losing

The study on the photoactivity of titanium dioxide, a semiconductor material, started with the Honda-Fujishima effect announced by Professor Fujishima in 1972. When a battery composed of a titanium dioxide electrode and a platinum electrode is irradiated with light, water decomposition occurs at about -0.5 V, oxygen is generated on the surface of the titanium dioxide electrode, and hydrogen is generated around the platinum electrode. This is a unique phenomenon that occurs at a potential far lower than +1.23 V, which is the normal oxidative decomposition potential of water. Professor Fujishima transferred this phenomenon to the conduction band of the valance band of titanium dioxide by ultraviolet light. It has been explained that the oxidation of water is caused by the holes generated at this time to generate hydrogen.

Titanium mineral is the ninth most common mineral on Earth, accounting for 0.6% of the lei and about 1% of the Earth's surface.

The band energy inherent in the photocatalyst material of the semiconductor nature-In the semiconductor material, it is a linear combination of atomic orbitals called the conduction band (E cb) without electrons and the shared band (E vb) filled with electrons. There are molecular orbitals. Accordingly, there is a forbidden space between these two bands that electrons cannot occupy. This is called band energy (Eg), and its magnitude corresponds to E cb -E vb . The photochemical system in which electrons (e-) in E vb are excited (excitation) after receiving such light energy and the electron (e-) and hole (h+) pairs are beneficially used is a light that can overcome the limitations of the existing reactor design. to enable the transmission of

The conversion of light energy into chemical energy or electrical energy through the process of photochemical reaction means that the generated electrons/holes are adsorbed to the photocatalyst, reduce/oxidize the material in the diffusion layer, or generate an electric current by the configured electrode circuit. It is possible by creating If this is used, it can be used for environmental purification by decomposing surrounding organic substances, as well as water decomposition hydrogen production, solar cells, etc.

Fine dust (fine dust, particle dust matter) is less than 10 micrometers (um), which is about 1/10 the size of a hair with a diameter of 50 - 70 micrometers (um), and when it breathes or penetrates into cells Even healthy people, as well as children and the elderly, may face serious diseases as their immunity declines. On the other hand, ultrafine dust refers to dust having a particle size of 2.5 micrometers (um) or less.

Recently, due to the rapid industrialization and acceleration of desertification in neighboring countries and some regions, a large amount of dust and fine dust are introduced into the atmosphere, and when the air containing such dust is directly inhaled, there are research cases that cause respiratory diseases. It has been reported a lot.

Therefore, the need for the development of an eco-friendly technology to purify the air in the surrounding environment including fine dust is very high, and it is one of the tasks to be solved very urgently in reality.
