Description

Air cleaner for removing heavy metals, harmful gases and odors {Air cleaner}

The present invention relates to an air purifier that is installed in a room including a vehicle and provides comfortable air by removing heavy metals, harmful gases and odors contained in the air.

In general, dust refers to particulate matter that floats or is blown down in the atmosphere, and is often generated from burning fossil fuels such as coal and oil, or from exhaust gases from factories and automobiles.

Depending on the particle size, dust is divided into total suspended particles (TSP) with a particle size of 50 μm or less and particulate matter (PM) with very small particle sizes, and fine dust is fine dust with a diameter of less than 10 μm. (PM10) and fine dust (PM25) with a diameter smaller than 25㎛.

As such, fine dust is so small that it cannot be seen with the naked eye, so it stays in the air and then penetrates the lungs through the respiratory tract or moves into the body along the blood vessels, adversely affecting health. The World Health Organization (WHO) has been providing air quality guidelines for fine dust since 1987, and in 2013, the International Agency for Research on Cancer (IARC) under the World Health Organization designated fine dust as a group 1 carcinogen.

In addition, with the development of industrialization, population density and the increase of vehicles, currently, urban air pollution by volatile organic compounds such as smog, exhaust gas, benzene, and toluene, cigarette smoke, fine dust and various chemicals is increasing. and various respiratory diseases are also on the rise.

In addition, when yellow dust occurs, the amount of dust accumulated on the Korean Peninsula is estimated to reach 46,000 to 86,000 tons, which is equivalent to 4,000 to 5,000 15-ton dump trucks.

Yellow sand contains toxic pollutants including soot, ash, carbon monoxide, other heavy metals (mercury, cadmob, chromium arsenic, lead, zinc, copper, etc.) and carcinogens by burning sulfur, one of the causes of acid rain. Viruses, bacteria, molds, parasites, antibiotics, asbestos, herbicides, plastic scraps, combustion products, phthalates and the like.

In addition, the amount of harmful substances generated in various office equipment and home appliances used indoors is too large.

An air purifier for purifying air against such air pollution is commercially available. The air purifier has a basic structure of a fan for inhaling and exhausting air and a filter installed at the front end of the air intake.

The filter typically employs a pre-filter for collecting dust with large particles, an activated carbon filter for adsorbing gases and odors in the air, and a HEPA filter for filtering out bacteria. An anion method to remove the ions is also proposed.

However, the conventional air purifier has a very weak problem in removing odors, organic compounds (VOC), and harmful gases contained in the air.

Since the conventional air purifier is mainly a filtering method, it only adsorbs dust, but there is no function to purify the filter, so there is no function to purify the filter, so the cost of replacing the filter occurs.

Korea Utility Model Application No. 20 - 2002 - 0018614 "Air Purifier"

An object of the present invention for solving the above problem is that the conventional air purifier can be used without filter replacement because it can restore itself by an adsorption decomposition method rather than a filtering purification method.

As a means of solving the above problems, the present invention provides an air purifier,

First and second suction chambers are respectively formed inside the housing, first and second filter chambers are formed between the first and second suction chambers, and an air clean room is formed between the first and second filter chambers, 2 The suction fan is inserted into the suction chamber and the first and second filter units are respectively inserted into the first and second suction chambers. When the air sucked through the suction port is supplied to the first and second filter chambers by the suction fan, the first and second filter units It provides an air purifier for removing heavy metals, harmful gases, and odors, characterized in that it filters heavy metals, odors, and fine dust.

As described above, the air purifier of the present invention consists of a filter in an adsorption decomposition method so that it can self-restore, so it can be used without filter replacement, parts can be reused, there is almost no after-sales maintenance cost, and consumers can easily clean themselves. have.

In addition, in the present invention, most of the parts materials were developed with natural materials, and the developer's own method failed repeatedly, and it is manufactured through the processes of extraction, pulverization, mixing, and strengthening.

In addition, since the present invention has a low-temperature drying function, carcinogens such as carbon monoxide and acetaldehyde do not occur during drying, and there is a safe effect.

In addition, the present invention has an excellent effect in removing heavy metals, fine dust, harmful gases, VOCs (organic compounds), odors, and the like.

In addition, the present invention has a sterilizing function, so it has an excellent effect in preventing infectious bacteria caused by viruses.

In addition, the present invention is an adsorption and discharge method using a nano-catalyst method and a photo-catalytic method developed independently.
