Description

High-energy ion disinfection and deodorization air purifier

technical field

The utility model relates to an air purifier, in particular to a high-energy ion disinfection and deodorization air purifier. It is used for indoor air purification in shopping malls, hospitals, hotels, offices, and families.

Background technique

The air purifiers currently on the market use the following technologies: (1) filter screen filtration technology. It achieves the purpose of removing dust, filtering bacteria, absorbing odor and releasing negative ions through coarse filter, activated carbon, high-efficiency air particulate filter (HEPA) filter and negative ion release. The structure is simple, the cost is low, and the sales volume is large. But its disadvantages are: the filtering and adsorption resistance of the filter is large, resulting in a large energy consumption; the adsorption capacity is limited, it is easy to be saturated, and it needs to be replaced frequently, resulting in high operating costs and short service life of the equipment. Secondly, the bacteria are only filtered, not killed, and there is a possibility of secondary pollution. Negative ions can only reduce dust but not remove dust, nor have the functions of sterilization and deodorization. (2) Ozone technology. It mainly uses the strong oxidation of ozone to kill bacteria and decompose odors. It has no function of dust removal. Ozone can only have obvious sterilization and deodorization effects in high concentrations, but high concentrations of ozone are harmful to the human body, especially the respiratory tract and lung organs, and even cause cancer. The United States prohibits the use of ozone for indoor air purification, and China also stipulates that the ozone concentration in indoor air must not exceed 0.16m ³ /h. Severe restrictions restrict its application in indoor air purification. (3) High voltage electrostatic technology. It is mainly composed of pre-filter, activated carbon adsorber and DC high-voltage electrostatic field and other components. Although the high-voltage electrostatic field has small resistance and low energy consumption, it can effectively remove dust and sterilize, and has obvious advantages, but the ability to eliminate odors is not good, so it must rely on activated carbon adsorption to help solve the odor problem, and once activated carbon is saturated, If it is not replaced in time, it will easily cause secondary pollution. If it is replaced frequently, it will cause an increase in operating costs. (4) Nano photocatalyst technology. It mainly uses the combination of ultraviolet light of a specific wavelength and nano-TiO ₂ to achieve the effect of killing bacteria and degrading odors. It has similar functions to ozone, but there is no strict limit on ozone concentration. However, with the development of nano photocatalyst technology so far, the efficiency of killing bacteria and degrading odors is still low, and it requires a long reaction time. At the same time, it does not have the function of dust removal or dust reduction, which affects the application and promotion of this new technology to a certain extent. .

In the meantime, it does not produce ultraviolet light, the ozone concentration is far lower than the national standard, and it releases high-concentration oxygen ion clusters, which can further purify the indoor air and give it a fresh and natural feeling. In addition, the main parts of the equipment only need to be sorted or cleaned, and do not need to be replaced, and there are no consumables, so the operating cost and maintenance cost are very low.

There is an electric control display screen 34 on the top, and an external power supply 35 is introduced from the bottom side of the rear part of the casing and connected with the electric control components. The cover plate 36 of the box body 31 can be opened, which is convenient for the installation of components and the maintenance and repair of equipment. Four wear-resistant rubber sliding rollers 37 are installed at the four corners of the casing bottom.

According to Figure 5: a low-noise centrifugal fan 41 is installed at the bottom of the box body 31, and a centrifugal fan with a maximum air volume of 200m ³ /h to 2000m ³ /h can be configured according to requirements. Install one or more groups (note: two groups in the figure) low-temperature plasma electric fields 42 on the upper part of the centrifugal fan 41 and fix them on the box body through the pull-out guide rail 43. At the windshield 33 places, one group of dual ion generators 44 are installed vertically, and are fixed on the casing 31 with screws.

When the utility model is in use, the dirty air inhaled by the centrifugal fan from the three air inlet windows at the lower part of the box body, the dust with larger particles in the air flow is firstly adsorbed by the pre-filter, and the adsorption rate is more than 50%. Then, enter the low-temperature plasma electric field, and the average wind speed is below 2.5m/s. Under the action of the high potential field and high-frequency pulse in the ionization zone, all the substances (including dust and bacteria) flowing through the airflow in the zone are activated into plasma. Under the high-energy impact of high-voltage high-frequency pulse, some The chemical bonds of odor molecules are broken and become harmless, odorless and stable small molecules. Then, these ionized substances enter the collection area. Under the action of Coulomb force and van der Waals force, the dust and bacteria are instantly absorbed by the high-voltage static electricity of the parallel plates and deposited on the plates, and the dust is firmly The ground is attached to the plate, the bacteria are killed by high voltage electricity, and part of the odor is decomposed. Then, the airflow enters the dual ion generator area. Under the containment of high-concentration oxygen ion clusters, various odors and toxic and harmful gases in the airflow, such as formaldehyde, ammonia, benzene series, hydrogen sulfide, TVOC etc., are immediately decomposed or degraded, and become carbon dioxide, water and other non-toxic, harmless and tasteless small molecular substances; bacteria, viruses and spores that may remain in the airflow are damaged at the same time, lose their activity, cannot reproduce and die. After the above synergy and sequential treatment, the overall effect of removing dust, killing bacteria, eliminating odors, decomposing toxic and harmful gases, and purifying the air is finally achieved. At the same time, as the clean air flow diffuses a large number of oxygen ion clusters outward, it can continue to interact with bacteria, odors and toxic and harmful gases in the indoor air, so that the bacteria in the indoor air are further killed, and various odors are further improved. Elimination, toxic and harmful gases can be further decomposed and degraded. After the reaction, the excess negative oxygen ion clusters will float in the indoor air, just like being in the fresh and comfortable atmosphere of nature, which will greatly improve people's work efficiency and quality of life.

The utility model can form a series of products to meet the needs of different indoor environments or meet the requirements of different customers for cleanliness. Stores, office rooms, conference rooms, waiting (aircraft) halls, entertainment places and other environments that need to improve air quality, as well as pet rooms, toilets, biological laboratories and other places that require special odor and stench elimination.
