Description

A multifunctional air purification device

technical field

The utility model relates to air purification equipment, in particular to a multifunctional air purification device, which belongs to the technical field of air purification.

Background technique

Air purifiers originated in fire-fighting purposes. In 1823, John and Charles Dean invented a new type of smoke protection device that enabled firefighters to avoid smoke attacks when fighting fires. Entering the 1980s, the focus of air purification has shifted to air purification methods, such as home air purifiers. While filters of the past were great at removing bad odors, toxic chemicals and gases from the air, but not mold spores, viruses or bacteria, new home and office air purifiers do more than just clean the air of toxic gases , It can also purify the air and remove bacteria, viruses, dust, pollen, mold spores, etc. in the air.

Now, air purifiers have been designed and produced in many different ways, and every technological change has brought significant results to the improvement of people's indoor air quality. And there is only one purpose for all this: hoping to purify indoor air to improve people's quality of life. With the rapid development of industrial modernization and the rapid advancement of urbanization, urban air pollution is becoming more and more serious, which greatly affects people's health. However, the air purification devices that people use now, such as the air purification layer of the indoor unit of the air conditioner, are only one layer of filter screen or filter plastic foam, which can only filter out large particles of dust in the air, and cannot degrade harmful gases in the air. Disinfect and sterilize to remove peculiar smell. Therefore, in a long-term airtight air-conditioned room, the air is dry, the smell is unpleasant, bacteria breed, the air is turbid, and the pollution is serious, which is not conducive to people's health. At the same time, there are also various air purification devices on the market, with functions of disinfection, sterilization and odor removal, and functions of dust removal and degradation of harmful gases, etc. These purification devices only purify various single purification functions. The integration of equipment makes it have multiple purification functions. Due to the influence of each other and the air with different pollution levels, they cannot perform their best purification functions, and even some purification devices have not exerted their due value, such as Using a purification device with the functions of dust removal and degradation of harmful gases at the same time in an air environment that is only polluted by dust, the equipment used to degrade harmful gases does not play its due role, but wastes its service life and energy consumption and so on. Another example is that when the dust content is relatively high or relatively low relative to the harmful gas content, the same purification mode is adopted, resulting in a greatly reduced purification effect. That is to say, the multi-energy purification equipment in the prior art has not been able to make corresponding adjustments according to the air in different environments and carry out targeted purification. Instead, it has performed rigid program purification in a brain-like manner, resulting in poor purification effects of some purification equipment. Even idling not only accelerates the damage speed of equipment, but also consumes energy in vain.

For example, when the main pollutants in the air are dust particles, etc., then control the follow-up air to mainly pass into the dust removal device for pretreatment, and then optionally carry out plasma purification treatment or photoelectric treatment (if the treatment is carried out, then The degree of purification of the treatment can be reduced, such as reducing the number of treatments of the low-temperature asymmetric plasma module or shortening the photoelectric treatment time, etc.). Conversely, if the main pollutants in the air are organic pollutants, then the subsequent air is simply subjected to dust removal treatment (for example, only yarn filter treatment) and then enters plasma purification treatment and photoelectric treatment. At the same time, if the concentration of organic pollutants is higher, Then open more low-temperature asymmetric plasma modules and increase the time for photoelectric processing.

The double-parallel structure can be adaptively adjusted to meet the level of dust particle pollutants in the air, reduce unnecessary processes, save equipment maintenance costs and reduce energy consumption. For example, when only simple dust removal treatment is required in the air (mainly because the coarser dust pollutants are less), then it is only necessary to pass the air through one or more layers of gauze filter treatment, without the need for other complicated follow-up Processing reduces the service life of subsequent equipment and materials. In the same way, when there are many fine dust pollutants in the air, the yarn filter treatment cannot meet the demand. At this time, activated carbon adsorption treatment (or yarn filter first and then activated carbon adsorption) can be used to remove dust in the air.

In the present invention, the plasma mechanism includes a plurality of low-temperature asymmetric plasma modules in which the plasma purification chamber is arranged.
