Description

A flexible plasma gas purification device

technical field

The utility model relates to the technical field of disinfection and sterilization, in particular to a flexible plasma gas purification device.

Background technique

With the improvement of people's living standards and the continuous development of economy and technology, air pollution has become more and more serious, resulting in many pollutants in the air that have seriously affected our health. In order to reduce air pollution, we have adopted a variety of air purification methods , these purification methods can reduce the level of air pollution to a certain extent, but there are also many problems. In traditional gas purification devices, the main technical means used are as follows:

1. Activated carbon purification technology: Utilize the porous structure of activated carbon itself to provide a large amount of surface area, so that it can fully contact with gas (impurity), thus endowing activated carbon with unique adsorption performance, but research shows that activated carbon technology is physical adsorption, efficiency Low, it will be released again after saturation and cause secondary pollution.

2. HEPA filter technology: The purification principle is similar to that of activated carbon, and it also belongs to physical adsorption. Its characteristic is that the qualified HEPA filter can reach 99% of the adsorption efficiency of 0.3 micron particles, but this filter is not washable, and the equipment It consumes more power, and the filter needs to be replaced regularly.

3. Ultraviolet purification technology: The disinfection and sterilization effect of ultraviolet rays is relatively significant, but it cannot remove particles and odors. At the same time, ultraviolet radiation is easy to cause damage to human corneas and skin, and cannot coexist with humans and machines.

4. Ozone sterilization technology: Utilizing the high activity of ozone itself, it can effectively kill bacteria, microorganisms, toxins, etc., but it cannot remove particulate matter such as PM2.5. In addition, excessive ozone is an invisible killer, which itself is corrosive, and at the same time It may also cause neurotoxicity, cause asthma, and affect lung function.

5. Photocatalyst purification technology: Photocatalyst can effectively remove dust, sterilize, and remove organic pollution such as formaldehyde. Harmful to the human body, it is not suitable for man-machine coexistence.

6. Negative ion purification technology: use the charged nature of negative ions to absorb suspended particles with positively charged ions, neutralize them to become uncharged, and then settle to purify the air. Its function is to reduce the concentration of suspended particles in the air, and this method cannot kill viruses, bacteria, or decompose pollutants.

The above-mentioned shortcomings can be overcome by using plasma technology, such as the low-temperature plasma air purification device of Patent No. 201510307671.7; The equipment structure of the purification device can only collect the gas inside the purification device for processing, and the structure is complex and bulky, which is difficult to meet the needs of portability.
