Description

A plasma fresh air system

technical field

The utility model relates to the technical field of air purification, in particular to a plasma fresh air system.

Background technique

With the rapid development of global industrialization, the environment has been continuously destroyed, resulting in a sharp deterioration of the quality of human living environment, especially in recent years due to haze, various germs, dust, etc., human life is surrounded by germs and fog in the haze.

Modern people live and work indoors for more than 90% of the time, and indoor air pollution is 2 to 5 times more serious than outdoor air, and sometimes even as high as 10 times. The World Health Organization announced that 100,000 people worldwide die of asthma every year due to indoor air pollution, 35% of whom are children. According to statistics, the prevalence of childhood asthma in my country is 2% to 5%, of which the prevalence of children aged 1 to 5 is as high as 85%. The main factor that causes human disease is the presence of a large number of harmful gases, tiny particles and pathogenic microorganisms in the air.

Among them, harmful gases include formaldehyde, benzene-based compounds, ammonia, volatile organic compounds, etc.

1) High concentrations of formaldehyde are toxic to the nervous system, immune system, liver, etc. Long-term exposure to high concentrations of formaldehyde can cause acute mental depression.

2) Long-term exposure to low concentrations of benzene compounds may cause chronic poisoning, decrease in platelets and leukocytes, and in severe cases, the hematopoietic function of the etched bone marrow will be impaired.

3) Difficulty in breathing, pulmonary edema, coma or shock after long-term exposure to low concentrations of ammonia.

4) The indoor total volatile organic compounds (TVOC) mainly come from paints, aqueous coatings, adhesives, etc. There are thousands of TVOCs found indoors, which are extremely harmful to the human body.

Microparticles: Suspended particles floating in the atmosphere for a long time, also known as respirable particles, respirable dust or fly ash. Particles with a particle size larger than 10 microns are usually deposited in the respiratory tract, and tiny particles with a particle size of 5 microns can enter the deep part of the respiratory tract, especially those with a particle size of less than 2.5 microns can directly enter the bronchi and alveoli, causing great harm to the human body. The smaller the particle size of the particles, the deeper the part that enters the respiratory tract, and the more serious the harm to the human body.

Pathogenic microorganisms: pathogenic microorganisms that can cause diseases in humans, animals and jobs.

Microorganisms that exist in the air, including bacteria and viruses, often attach to the surface of tiny particles and spread various infectious diseases.

In this case, various fresh air systems and air purification products for air purification stand out, trying to improve our living environment, especially the indoor environment, through fresh air systems or air purification equipment.

Therefore, the fresh air system has increasingly become a necessity for a healthy life.

2) Even after living for several years, toxic and harmful gases still haunt our lives;

3) There is a lot of dust in the room, mosquito bites, noise, etc. affect our rest and study;

4) After opening the window, rain, dust, thieves, and children will make people worry;

5) Water vapor accumulates, and clothing and valuables are prone to mildew and damp;

6) Cigarettes in the room, lampblack in the kitchen, and peculiar smell in the bathroom;

7) The lack of ventilation caused by the room type is like darkness, and there is no window opening in the north and south;

8) In an air-conditioned room, fatigue, headache, flushing, drowsiness, commonly known as "air conditioning disease";

9) The impact of SARS and other airborne diseases on people's health awareness;

10) Promulgation and mandatory implementation of relevant regulations such as indoor pollution control specifications and requirements for fresh air volume of small central air conditioners.

Although the fresh air system plays a very important role in healthy life, the traditional fresh air system still has many defects and deficiencies:
