Description

Air cleaning device for ducts using plasma {AIR CLEANING DEVICE FOR DUCT USING PLASMA}

The present invention relates to an air purifier for a duct using plasma, and more particularly, is installed in a duct provided in a multi-use space such as a trap, public transportation, or an indoor facility, and generates low-temperature plasma to float in the air in the duct. It relates to an air purifier for a duct using plasma capable of sterilizing bacteria and viruses and purifying air.

In general, fine dust or dust is dust whose particles are so small that it is invisible to the eye, and is an air pollutant containing sulfur dioxide, nitrogen oxides, lead, ozone, carbon monoxide, and the like.

Fine dust is fine dust with a particle size of 10 μm or less that is generated in automobiles, factories, etc. and floats in the air for a long time, and is also called PM 10.

If the particle is less than 2.5㎛, it is written as PM 2.5, and it is also called 'ultrafine dust' or 'ultrafine dust'.

Scientifically, it is called an aerosol.

Fine dust is also called suspended dust, particulate matter, etc., and has slightly different meanings depending on the name.

Particulate matter has a diameter of about 100 μm to 10 nm, and if the diameter is larger than this, the residence time in the atmosphere is very short due to gravity.

In addition, fine dust is a very small substance that is invisible to our eyes and is a particulate matter with a diameter of 10 μm or less that floats or scatters in the air, and fine dust is a substance that has a great effect on the human body.

The causes of emission of fine dust are divided into artificial and natural occurrences.

Artificial causes can be caused by fine dust from China, exhaust fumes from factories, and incineration of waste.

Natural causes include dust from sandstorms, volcanic ash, and dust from forest fires, and sea salt particles also have a great impact on areas located near the sea.

In modern times, due to urban development and industrial development, pollutants generated from factories and vehicles are excessive in the air, and the damage and inconvenience caused by fine dust among them has reached a point where it is indescribable.

In particular, fine dust penetrates deep into the human respiratory system and causes respiratory diseases such as asthma, bronchitis, and allergic rhinitis, and is a major cause of eye diseases such as conjunctivitis and dry eye syndrome, and causes allergic rhinitis of skin diseases. In particular, infants, teenagers, and the elderly are vulnerable to fine dust.

The air pollution accident that killed 20 people in Donora, Pennsylvania, USA in 1948 and the London smog that caused about 4,000 deaths in 1952 are representative examples of how fine dust affects the human body.

Since then, various epidemiological studies have been conducted on the effects of fine dust on the human body, and it has been found that fine dust particles of 10 μm or less are particularly likely to have harmful effects on the human body, such as increasing the incidence and mortality of vulnerable groups. .

After these research results came out, governments of each country began to prepare air pollution measures, and air pollution standards were also prepared to reduce the harmful effects of fine dust on the human body and the environment.

On the other hand, bacteria and viruses that pose a fatal threat to human survival can cause human-to-human transmission.

Bacteria, along with archaea and eukaryotes, are representative taxa of prokaryotes that occupy one of the three domains of living organisms.

More than 13,000 species have been known so far, and about 600 new species are reported every year, and the number is continuously increasing.

Bacteria surpass other biota in their distribution to the extent that they can be found anywhere on the planet, and their metabolic diversity is also phenomenal.

Bacteria, along with various pathogens, contain industrially important taxa, and are inseparably related to humans in daily life. It provides important information that can be the basis for a holistic understanding.

Bacteria are unicellular organisms made up of one cell, but they are equipped with organs to live on their own.

In other words, they can reproduce by eating their own nutrients and making their own organic matter.

Unlike the above bacteria, viruses have a simple structure composed of nucleic acids such as DNA and RNA and proteins.

Most organisms make necessary proteins using organs such as ribosomes based on genetic information in DNA.

However, because viruses do not have organs such as ribosomes, unlike bacteria, viruses cannot produce the necessary energy or organic matter on their own.

So viruses do not belong entirely to the category of organisms.

This is because they cannot survive alone and only multiply by borrowing the power of a living creature that becomes a host.

A disease that is collectively prevalent in living organisms, including humans, through bacteria or viruses as described above is called an infectious disease.

Historically, from the Black Death, a pandemic in Europe in the 14th century, to the recent novel coronavirus, mankind has been constantly struggling with the worst infectious diseases.

Infectious diseases are an unavoidable enemy to mankind. The Spanish flu, which terrified mankind more than 100 years ago, claimed more than 25 million lives. In 2014, the Ebola virus swept across Africa.

As such, the World Health Organization (WHO) defines the 21st century as the era of infectious diseases.

This is because the speed of propagation is beyond imagination as transportation develops and contact between people soars.

Photocatalyst and UV sterilization are sterilization using light, and the photocatalyst initiates and proceeds with an electronic board or light during a chemical reaction.

The photocatalyst refers to a compound that initiates a photochemical reaction by absorbing light energy from a light source, including the sun, and promotes the photochemical reaction as a catalyst.

UV sterilization is a method of sterilization using ultraviolet rays. Ultraviolet rays are light with a wavelength range of 10 to 400 nm (energy range of 3 eV to 124 eV), and are a general term for electromagnetic waves with a wavelength shorter than visible light and longer than X-rays.

Among the ultraviolet rays as described above, ultraviolet C having a wavelength range of 100 to 280 nm and an energy range of 4.43 to 12.4 eV has a sterilizing effect.

As a prior art related to fine dust reduction and sterilization of bacteria and viruses as described above, Korean Patent Publication No. 10-2010-0095890 absorbs moisture generated by condensation of fine dust mixed in the air and uses an absorbent cloth. An air purifier for fine dust to filter the air is disclosed, and domestic registered utility model publication No. 20-0425412 first treats dust, fine dust and odor, and then mixes the odor gas with a purification solution to reduce the residence time A device for purifying polluted gas using a deodorization tower and a mixing system configured to improve the performance of purifying polluted gas by increasing the contact area with and to extend the replacement cycle of the purifying solution is disclosed, and Korean Patent Publication No. 10-2018-0051923 A gas processing chamber installed in a pollutant gas transfer path to treat and discharge pollutant gas introduced into the gas processing chamber, an electromagnetic wave generator generating and providing electromagnetic wave waves into the gas processing chamber, and maintaining a uniform temperature inside the gas processing chamber An atmospheric environmental pollutant gas and fine dust reduction system is disclosed, characterized in that it includes a heat generating and temperature adjusting unit and a plasma generator for maintaining the inside of the gas treatment chamber in a plasma state.
