Description

Fine dust reduction device {APPARATUS FOR REDUCING FINE DUST}

The present invention relates to an apparatus for reducing fine dust, and in particular, a filter stacked up and down in the process of suctioning air containing fine dust in one side of a pole structure fixed outdoors or indoors by a vacuum suction method and introducing it to the lower side, and Ultraviolet rays are passed to filter fine dust, and the filtered clean air is discharged to the outside through the other side of the pole structure so that it can function as an air purifier, and dust from the filters stacked up and down will accumulate. The present invention relates to a device for reducing fine dust with an improved structure so as to be able to easily remove the case and extend the life of the filter unit.

In recent years, as the quality of life improves and interest in health increases, an IoT-based environment for inducing healthy life patterns by monitoring everyday pollution factors that threaten human health, such as UV index and fine dust concentration around users, in real time. The need for management system development is being emphasized.

In addition, due to rapid industrial development, the ozone layer is destroyed, and the amount of harmful UV rays reaching the ground is gradually increasing, and leisure activities increase due to the improvement of the living standard of modern people, and the frequency of UV exposure gradually increases. Harmful effects are emerging.

Dust is classified into total dust (TSP) of 50 μm or less and particulate matter (PM) having a very small particle size, depending on the size of the particles.

Fine dust is divided into fine dust PM-10 with a diameter of less than 10㎛ and fine dust PM-25 with a diameter of less than 2.5㎛. Since it is so small that it is invisible, it stays in the atmosphere. It penetrates the lungs or blood vessels through the respiratory tract. Therefore, it can have a negative effect on your health by moving into the body.

In particular, the World Health Organization (WHO) has proposed air quality guidelines for fine dust since 1987, and in 2013, the International Cancer Research Institute (IARC) designated fine dust as a group 1 carcinogen that has been confirmed to be carcinogenic to humans. I did.

The composition of fine dust may vary depending on the region, season, and weather conditions.

In general, it is composed of lumps of sulfate, nitrate, etc. formed by reacting air pollutants in the air, carbons generated when fossil fuels are burned, black substances formed by soot or smoke, and minerals generated from soil dust on the surface.

Fine dust composed of these components is through a chemical reaction in which sulfuric acid emitted during the combustion of fossil fuels is combined with water vapor and ammonia in the atmosphere, or nitrogen oxides from automobile exhaust gas are combined with water vapor, ozone, and ammonia in the atmosphere. Occurs.

On average, the concentration of fine dust in Korea is still high when compared to cities in major developed countries, 15 times, 21 times and 23 times higher than that of the United States, France, and Paris, respectively, and it can be seen that it is on an increasing trend.

This is because the population density is high, the urbanization and industrialization are highly advanced, so the amount of fine dust per unit area is high, and the geographical location and weather conditions are not advantageous.

In addition, fine dust is frequently generated due to atmospheric congestion caused by continental high pressure that frequently forms around Korea.

Recently, various methods and types of fine dust reduction devices have been developed to reduce fine dust.

As a background technology of the present invention, Korean Patent Application Publication No. 10-2018-0073322 (hereinafter, Document 1), Korean Patent Application Publication No. 10--1628076 (hereinafter, Document 2), Korean Patent Application Publication No. 10--1801517 No. (hereinafter, Document 3) and Korean Patent Publication No. 10-0640728 (hereinafter, Document 4).

Patent Document 1 discloses a fine dust reduction device and method by spraying droplets having a specific charge opposite to the electric characteristics charged according to the mutual collision of fine dusts of 10 μm or less or the surrounding environment in a specific space through an electrohydrodynamic nozzle. It is an invention that removes fine dust.

The device for reducing fine dust in Patent Document 1 uses a method in which droplets and fine dust interact on the receiving chamber and are combined into a neutral conjugate to settle naturally. When applied to storage tanks or non-point pollution facilities, conductive nanomaterials are used. Water droplets can cause water pollution problems.

In addition, in the apparatus of Patent Document 1, the neutral combination only naturally settles, and there is no configuration for discharging it, so the efficiency may be deteriorated by the combination accumulated on the floor inside the apparatus over time.

Patent Document 2 relates to a device for removing fine dust to create a comfortable indoor environment by removing fine dust in the air through cleaning and purification while polluted air introduced into the fine dust removing device is buried in sprayed particles.

In the apparatus of Patent Document 2, the spray nozzle is located only in the center of the reservoir lid member, and contaminated air is introduced through a vent located at the edge of the reservoir lid member, so that the sprayed water is difficult to contact with the polluted air.

In addition, as the water sprayed from the spray nozzle reuses water that has been in contact with the contaminated air, the spray nozzle may be clogged by fine dust, or the spraying force may be weakened, resulting in a problem that the efficiency of fine dust decreases.

Patent Document 3 relates to a fine dust collector that is installed on the upper surface of a vehicle as a fine dust collector or installed inside a house to remove fine dust contained in the air and then discharge clean air to the outside.

Since the collector of Patent Document 3 is filled with only ⅓ of water in the first filtering unit, air containing fine dust may be discharged to the outside by sequentially moving the second filtering unit and the third filtering unit where there is no water.

In addition, in the collector, water containing fine dust is introduced into the water tank through the transfer pipe, and the water in the water tank is contaminated with fine dust, and thus the efficiency of the first mesh may be reduced. have.

Patent Document 4 relates to a device that effectively adsorbs harmful substances in the air by maximizing the contact area between indoor air and washing water flowing into a purifier for a wet air purifier.

In the apparatus of Patent Document 4, a purification device is placed in a water tank containing washing water, and contaminants of the air may be contaminated by the air introduced through the blower and the water sprayed from the injection unit falls into the washing water.

In addition, problems such as clogging of the injection unit or foreign matter being caught by contaminated washing water may occur, resulting in a problem of lowering than the efficiency that was initially driven.

In other words, among the existing fine dust reduction technologies, the spraying method using water has a disadvantage in that the reduction range is limited, and the washing water is secondary contamination.
