Description

Fine dust reduction device {DEVICE FOR REDUCING FINE DUST}

The present invention relates to a fine dust removal device, and more particularly to a mobile fine dust reduction device for reducing fine dust in the atmosphere.

The state in which particulate matter (solid or liquid state) is suspended in the air is generally called aerosol, and is generally called dust.

Although the particle size range of the dust is 0.001 μm to 1000 μm, dust of 70 μm or more is settled upon occurrence, so dust of 70 μm or less is generally referred to as Total Suspended Particle (TSP).

Here, the total dust (TSP) may be referred to as total suspended dust, total suspended particulate matter, or total particulate matter.

Particularly, the particle size of the dust having a particle size of 0.1 μm or less is called ultra range, and the dust having such a particle size of the ultra range is called fine dust.

The kind of such fine dust is as follows.

PM-10 (particles less than 10 ㎛) penetrates into the lungs of the human body, which is a direct cause of various respiratory diseases, and weakens the immune function of the human body.

PM-2.5 (particles less than 2.5 μm) have a particle size of less than 2.5 μm and are called ultra fine dust.

The causes of such fine dust include artificial and natural occurrences.

Anthropogenic emissions include soot from factories, thermal power plants or automobiles.

In addition, the natural occurrence is fine dust from China, sand wind dust, dust from volcanic ash or wildfire.

The main components of fine dust are nitrates and sulfates.

Recently, disease damage due to fine dust is gradually increasing, as follows.

1) Increase in elderly mortality

Whenever the concentration of fine dust (PM-10) in Seoul increases by 10 μg (m / g), the mortality rate of air-sensitive populations, such as the elderly aged 65 and older, increases by 0.4%.

2) pregnant women and fetuses

Increasing the fine dust concentration by 10 ㎍ / ㎥ increases the risk of birth of low birth weight infants by 5.2% to 7.4%, and the risk of stillbirth between four and nine months of pregnancy increases from 8.0% to 13.8%.

In addition, the concentration of fine dust (PM-10, dust having a diameter of 10 μm or less) is closely related to low birth weight birth, stillbirth and birth defects.

3) Asthma

Deep dust penetrates the lungs and accumulates in the bronchus and lungs, which is a direct cause of various respiratory diseases, and reduces the body's immune function.

4) headache

When humans drink fine dust with high concentrations of harmful heavy metals such as lead, arsenic, and zinc, which are produced when burning anthracite, they cause coughing, trouble with the neck and skin, headaches, dizziness, and difficulty breathing. Cause

5) myocardial infarction

Sulfate ions or nitrate ions in the fine dust stimulate the white blood cells, causing inflammation of the blood vessel walls, leading to vascular diseases such as atherosclerosis, cerebral infarction, and myocardial infarction.

6) Atopy

Ultra-fine dust smaller than the pores penetrates into the pores, causing skin diseases such as atopy.

7) plant-related diseases

While floating in the air, it absorbs and scatters light, accumulates on the leaves of plants and inhibits photosynthetic assimilation, respiration, and transpiration, which adversely affects plant growth.

Since the fine dust has a disease-related effect on the human body, it is necessary to share the severity of the fine dust at the national level and to take measures.

5 is a view showing a configuration in which a fire truck is connected to the fine dust reduction device according to the present invention, Figure 6 is a view showing a configuration in which a fire hydrant is connected to the fine dust reduction device according to the present invention.

Referring to FIG. 5, in the fine dust reduction apparatus 1000 according to the present invention, the pump 600 moves the water stored in the water storage tank of the fire truck 800 by the fire hose 810.

That is, by the pumping of the pump 600, the water stored in the water storage tank of the fire truck 800 is moved to the distribution unit 500 through the fire hose 810.

In particular, when fire occurs in order to extinguish a fire, the fire truck 800 always stores water in a water storage tank at all times.

As such, the water stored in the water storage tank of the fire engine 800 may be withdrawn for water supply regardless of the fire suppression.

Therefore, when the degree of fine dust accumulation is high and a fire does not occur, water stored in the water storage tank of the fire engine 800 may be used to reduce the fine dust.

Referring to FIG. 6, in the fine dust reduction apparatus 1000 according to the present invention, the pump 600 moves water by the hydrant hose 910.

That is, by pumping the pump 600, the water is moved using the hydrant hose 910 connected to the hydrant 900.

The operation relationship of the fine dust reduction apparatus 1000 which concerns on this invention which consists of a structure as mentioned above is demonstrated.

In the fine dust reduction apparatus 1000 according to the present invention, when water is supplied to the distribution unit 500 through a pipe, water is supplied to the plurality of blowers 110, 120, and 130 by pumping of the pump 600. .

The pump 600 also serves to supply water from the water storage tank of the fire engine 800 to the distribution unit 500.

Of course, the water stored in the water storage tank of the fire truck 800 may be moved by the pump of the fire truck 800 itself.

As such, the water supplied to the plurality of blowers 110, 120, and 130 is the pumping pressure of the pump 600, the height difference between the one side communicating with the inside of the spray tank 100, and the respective blowers 110, 120, One side of 130 forms a centrifugal force in the spray tank 100 by a configuration that is bent at a predetermined angle with the area mounted on the side surface 100 of the spray tank.

The water decomposes while colliding with the inner wall of the spray tank 100 by such a centrifugal force and becomes fine water particles.

This phenomenon is similar to the principle of cyclone dust collector.

However, although the cyclone dust collector is dust-collected in the downward direction, the fine dust reduction device 1000 according to the present invention is to spray the fine water particles having a centrifugal force in the upward direction.

That is, in the fine dust reduction device 1000 according to the present invention, the water in the spray tank 100 is made smaller than the water particles while passing through the truncated cone 140, the fine water particles are made from the air conditioning unit 400 Due to the strong wind supplied, it is injected and raised while forming centrifugal force to the outside (upper part) of the spray tank 100.

The fine water particles thus raised are combined with the fine dust in the air.

As a result, the fine dust reduction apparatus 1000 according to the present invention combines the fine water particles with the fine dust present in the air, thereby increasing the size of the fine dust to 70 μm or more and dropping it onto the ground.

In addition, new air containing fine dust is introduced into the mobile fine dust reduction device and cross-washed by inducing the airflow by changing the ambient temperature of the water particles generated when the water particles are smallly split.

In addition, there is an effect that the air containing the fine dust can be introduced into the mobile fine dust reduction device without the air transport means by the temperature change generated by the water particles are split into fine water particles.

5 to 9 are views showing various examples in which the fine dust reduction apparatus according to the present invention is installed.

5 to 9, the fine dust reduction apparatus 1000 according to the present invention may be installed around a park in a city or near a mountain.

In addition, the fine dust reduction device 1000 can be installed around the river or lake.

When installed near a river or a lake, the water of the river or the lake may be used instead of the fire engine 800 or the fire hydrant 900.

In addition, it can be installed on highways, urban roads, rooftops of buildings, thermal power plants, factories, steel mills, etc., where a lot of fine dust is generated.
