Description

Fine dust purification device using shade curtain {FINE DUST PURIFICATION DEVICE USING SUNSHADE CANOPY}

The present invention relates to a device for purifying fine dust using a shade, and more specifically, by utilizing a shade installed near a crosswalk on a road or in a park, clean air from which fine dust has been removed is supplied by a blowing fan in the summer season. It relates to a fine dust purifying device using a shade curtain to supply warm wind by supplying it to people in the lower part and supplying warm wind by heating air from which fine dust has been removed with a heater in the winter season.

In general, dust refers to particulate matter floating in the air.

Such dust is generated a lot in exhaust gas from vehicles running on roads or burning fossil fuels such as coal or oil at various industrial sites.

In general, dust can be classified into Total Suspended Particles (TSP) and Particulate Matter (PM) having a particle size of 50 μm or less depending on the particle size.

Here, fine dust can be further classified into fine dust (PM10) with a diameter smaller than 10 μm and ultrafine dust (PM2.5) with a diameter smaller than 2.5 μm.

Fine dust of PM10 is about 1/5 to 1/7 smaller than the diameter of a human hair (50 to 70㎛), and ultrafine dust of PM2.5 is only 1/20 to 1/30 of a human hair. .

Fine dust or ultrafine dust floating in the air in such a small size not only directly damages the human body, but is also a major cause of climate change.

Fine dust or ultra-fine dust that adversely affects human life is generated in a considerable amount even in vehicles.

Therefore, the method of treating or reducing fine dust only in industries has limitations in treating fine dust.

The sources of the fine dust can be divided into natural and artificial sources, and natural sources include soil dust, plant pollen, and the like.

In addition, the artificial sources of fine dust are soot generated when fossil fuels such as coal and oil are burned in boilers or power generation facilities, automobile exhaust gas, flying dust generated at construction sites, raw materials in the form of powder in factories, and subsidiary material handling processes. There are powder components in the air, smoke from incinerators, etc.

In addition, the source of fine dust can be classified into a primary occurrence that comes out of the chimney as fine dust in a solid state, and a secondary occurrence in which a gaseous substance from the source causes a chemical reaction with other substances in the air to become fine dust. .

The secondary generation occurs when sulfur oxides emitted during the combustion of fossil fuels such as coal and oil combine with water vapor or ammonia in the air, or nitrogen oxides from automobile exhaust combine with water vapor, ozone, ammonia, etc. in the air. It is created through a chemical reaction.

The reason why the secondary generation is important is that even in the metropolitan area, the proportion of secondary generation due to chemical reactions is so high that it accounts for about 2/3 of the total amount of fine dust (PM2.5) generated.

[Table 1] below shows the source distribution of fine dust (PM10) and ultrafine dust (PM2.5).

Source distribution of fine dust (PM10) and ultrafine dust (PM2.5) division manufacturing
Combustion production process road trip
pollutant rain road
mobile pollutant energy
industrial combustion non-industrial combustion PM10 (%) 65 6 12 13 4 2 PM2.5 (%) 52 8 16 17 5 2

First, the sources of fine dust (PM10) are 65% in the combustion process of manufacturing, 6% in the production process, 12% from road transport pollutants, 13% from non-road transport pollutants, 4% from combustion processes in the energy industry, and 4% from non-industrial combustion. It occurs in about 2% of the process.

And the sources of ultrafine dust (PM2.5) are 52% in the combustion process of manufacturing, 8% in the production process, 16% from road transport pollutants, 17% from non-road transport pollutants, 5% from combustion processes in the energy industry, About 2% occurs in non-industrial combustion processes.

In other words, it can be seen that fine dust or ultra-fine dust is frequently generated in industrial sites, but also in road transport pollutants or non-road pollutants that are difficult to collect and treat.

[Table 2] below shows the distribution of fine dust from mobile pollutants.

Distribution of fine dust in mobile pollutants division truck special car RV car van bus PM2.5 (%) 69 One 22 0.3 5 3

That is, the amount of ultrafine dust generated from mobile pollutants is 69% for trucks, 1% for special vehicles, 22% for RVs, 0.3% for passenger cars, 5% for vans, and 3% for buses.

In addition, fine dust is also generated at home, and is often generated when cooking food using a gas range, electric grill, or oven used at home.

Fine dust generated during cooking occurs when initial particles of 15 to 40 nm in size are generated on the surface of food and condensed with moisture and oil in the ingredients.

In addition, the degree of occurrence of fine dust varies depending on the recipe, and cooking using oil to bake or fry generates more fine dust than cooking cooked.

As described above, when the source of fine dust is fixed, it is relatively easy to collect and treat it.

However, if the source of the fine dust is not fixed and moves, or if the fine dust cannot be collected in one place, it is excluded from the fine dust treatment facility.

Meanwhile, as shown in [Table 3], the International Agency for Research on Cancer (IARC) defines fine dust as a Group 1 carcinogen.

Classification of carcinogens by the International Agency for Research on Cancer (IARC) division Main Content example Group 1 Found to be carcinogenic to humans Asbestos, benzene, fine dust Group 2A Substances likely to be carcinogenic to humans DDT, inorganic lead compounds Group 2B Substances that may be carcinogenic to humans gasoline, cobalt Group 3 Substances whose carcinogenicity is uncertain and it is not possible to classify them as carcinogenic to humans. phenol, toluene Group 4 Substances that are unlikely to be carcinogenic to humans caprolactam

When the above fine dust accumulates in the bronchi of the human body, phlegm is formed, coughing becomes frequent, and the mucous membrane of the bronchial tube becomes dry, allowing bacteria to easily penetrate.

Therefore, people with chronic lung diseases have a greatly increased incidence of infectious diseases such as pneumonia.

In addition, fine dust is very small in size, so it can penetrate into blood vessels through alveoli and cause inflammation.

According to the Korea Centers for Disease Control and Prevention, every 10㎛/㎥ increase in fine dust (PM10) concentration resulted in a 2.7% increase in the hospitalization rate and a 1.1% increase in mortality due to chronic obstructive pulmonary disease (COPD).

In particular, it was found that the incidence of lung cancer increased by 9% for every 10㎛/㎥ increase in the concentration of ultrafine dust (PM2.5).

As such, fine dust or ultrafine dust (hereinafter collectively referred to as 'fine dust') not only causes great damage to the human body, but also causes climate change on the earth.

Therefore, it is also important to seek measures to reduce fine dust as much as possible, and to treat or reduce already generated fine dust as quickly as possible.

On the other hand, the temperature in the atmosphere generally decreases by about 0.6°C for every 100 m increase in altitude.

This temperature inversion phenomenon often occurs in seasons with large diurnal temperature differences or in mountainous basin areas.

In general, air is less dense as it gets hotter, so hot air moves up and cold air moves down.

However, when the above temperature inversion occurs, the heavier air is located at the lower altitude and the lighter air is located at the higher altitude, so that the air does not move up and down due to the difference in weight.

As a result, air pollutants such as fine dust, which are mainly generated on the ground, stay in the ground layer and their concentration gradually increases. The frequency of such temperature inversions has increased in recent years.

On the other hand, climate change around the world is getting worse due to the influence of global warming, and the resulting damage continues to increase.

Accordingly, the government and local governments provide forecasts of fine dust conditions as well as weather forecasts through TV, newspapers, the Internet, and mobile phones.

In addition, the government protects and manages the heat wave vulnerable groups through the heat wave forecasting and warning system.

Among them, the heat wave shade to avoid strong sunlight was installed for the first time in Dongjak-gu, Seoul in 2013, and its installation is gradually expanding.

1 shows an example of a heat wave shade curtain installed near a crosswalk on a road or in a park.

As shown in FIG. 1, the conventional heat wave shade curtain includes a base 1 fixed to the ground, a vertical pillar 2 extending vertically from the base 1, the vertical pillar 2 and a parasol ( 5), a parasol 5 provided at the end of the connecting pillar 3 to create a shade, and a parasol 5 provided at the end of the connecting pillar 3 to support the parasol 5 A support column 4 for supporting, a plurality of parasol support legs 6 for supporting the unfolded parasol 5 from the lower portion, and a fixing member 7 for fixing the lower ends of the parasol support legs 6 together. It is done by

As of 2022, it is understood that a total of 2,500 shade shelters have been installed at crosswalks and parks in Seoul.

The shade shelters include picnic table-type shelters installed in parks, etc. for family users, hut-type shelters installed in places with views of the Han River, and membrane-structured shelters installed in the form of large parasols around the trails (hereinafter collectively referred to as "shade" to do).

In addition, Incheon City has installed and operated more than 1,000 shade tents from 2017 to the present, and these shade tents are expanding nationwide.

However, the above-described conventional shade curtain simply performs only a function of blocking sunlight.

Accordingly, when a large number of people gather under the shade, there is a disadvantage that the effect of the shade is reduced.

In addition, the conventional fine dust removal method has a problem that it is concentrated only in industrial sites, and fine dust generated in roads or human living spaces is left unattended.
