The present invention relates to a fine dust blocking system, and more particularly to a fine dust blocking system for improving the air quality by blocking the discharge of fine dust through the exhaust gas exhaust facilities of the thermal power plant chimney or building ventilation facility.

As the industry develops, the pollution of the environment becomes serious and governments and international organizations that recognize the seriousness of the air pollution set the standards for the emission of air pollutants and require the countries to comply with them.

At this time, fine dust, one of the air pollutants, is a floating material in the air with various complex components. It is a PM10 (Particulate Matter 10) dust with a diameter of 10 μm (micrometer, 1 μm = 1000/1 mm) or less. It is called).

Most of them are emitted through automobile exhausts or factory chimneys, and are small dusts that are blown out during Chinese yellow dust or heavy smog.

In addition, fine dust having smaller particle size among fine dust is called ultra fine dust, and is called PM25 as dust having a diameter of 25 μm or less.

The number of fine dust is strictly regulated in various countries in the world, and the conditions of fine dust existing in the air are strictly set and managed in Korea.

Meanwhile, various types of harmful substances harmful to the human body are discharged from the exhaust gas in the thermal power plant that burns fossil fuel and generates power from the thermal power plant, incinerators that incinerate industrial waste or general household waste, and building ventilation facilities.

Among these harmful substances, the fine dust and the ultrafine dust are absorbed by the human body, and when accumulated, it causes various diseases as well as adversely affects the natural environment. .

In particular, ultra-fine dust is much smaller than fine dust, so it cannot be filtered out of the airways, and most of them penetrate into the alveoli, causing heart disease and respiratory diseases.

For the reasons mentioned above, workplaces that use incinerators and fossil fuels around the world are regulated by the law, and in Korea, the 'Environmental Notice' limits the amount of hazardous substances contained in the emissions. have.

Accordingly, in order to reduce the concentration of harmful substances contained in the exhaust gas, power plants and incinerators are installed with hazardous substance prevention facilities.
