Description

High-voltage corona high-efficiency air purifier

technical field

The utility model belongs to the technical field of air purification, and relates to indoor air purification equipment, in particular to a high-voltage corona high-efficiency air purifier.

Background technique

In real life, pollutants such as dust, bacteria, viruses, and peculiar smells in the air pose a great threat to people's health. In order to purify indoor air, various air purifiers (machines) have emerged as the times require, mainly including filter adsorption type, electrostatic dust collection type, negative ion type, ozone type, and photocatalyst type. The filter-adsorption air purifier can effectively absorb the suspended particles in the air. Even with the activated carbon filter, it can only absorb a small part of the odor. Using the HEPA filter as the filter medium can only filter out smaller particles and large particles. Some bacteria, but viruses, poisonous gases, volatile gases, and most odors cannot be removed, and instead circulate in the air; electrostatic dust collection air purifiers use the principle of electrification of electrode plates to absorb suspended particles, but cannot effectively block bacteria, and To deal with volatile and harmful gases, the effect will be weakened when the air flow is increased, and the applicable area is small; although the negative ion air purifier can decompose the peculiar smell and attached smoke in the air, it cannot remove viruses, poisonous gases and volatile gases ;Ozone-type air purifiers use high-voltage electrodes to generate ozone and oxidize substances to remove the toxicity of some substances and achieve the purpose of sterilization and disinfection. However, when ozone generally reaches an effective concentration, it is enough to harm the human body; Harmful gases such as benzene and benzene produce oxidation-reduction effects, but it may affect indoor colored walls and furniture surface paint, and it will take a certain time to work. In addition, once ultraviolet rays leak out, they will be harmful to the eyes and skin. Although there are air purifiers developed in combination with the above several air purifiers on the market, there are still some of the above-mentioned shortcomings more or less.

Contents of the invention

The utility model aims at the above-mentioned problems existing in the existing air purifier, and provides a high-voltage corona high-efficiency air purifier with novel structure, multiple functions, good purification effect, and capable of dedusting, sterilizing, disinfecting and deodorizing ambient air. Purifier (hereinafter referred to as air purifier).

The technical solution of the utility model:

The air purifier of the utility model is composed of an air inlet, an initial filter, a high-voltage shielding net, an activated carbon filter, a high-voltage corona device, a HEPA filter, an ozone decomposition device, a fan, an air outlet, and a power control, and is characterized in that: The initial filter screen, activated carbon filter screen, high-voltage corona device, HEPA filter screen, and ozone decomposition device are combined into a purification channel in sequence.

In the utility model, the high-voltage corona device is composed of a high-voltage generator, a high-voltage discharge network, a high-voltage frame, and a high-voltage corona wire.

The utility model uses a fan to make the indoor air pass through the purifier box, and the dust of larger particles is intercepted by the primary filter; the dust is further absorbed by the activated carbon filter; after the high-voltage discharge network is connected to a negative high voltage of 6.8KV, negative ions are generated and residual dust After the particles are combined with negative ions to be negatively charged, they tend to deposit on the surface of the positively charged HEPA filter; at the same time, the high-voltage corona device generates ozone, which has the effect of sterilization and sterilization; the HEPA filter further removes dust and bacteria; ozone decomposes The device decomposes the residual ozone. After the indoor polluted air is treated, it becomes fresh air with a proper amount of negative oxygen ions, dust-free, sterile, non-toxic and odor-free.

The utility model has the advantages of being easy to use, and can perform dust removal, sterilization, disinfection, and deodorization on the ambient air with high efficiency, and at the same time has no side effects on the human body, and the output fresh air contains an appropriate amount of negative oxygen ions, which is beneficial to human health. Especially suitable for use in public places.
