Description

An activity-adjustable air purifier

technical field

The invention relates to the technical field of air purification, in particular to an activity-adjustable air purifier, which can be used for central air conditioning or central ventilation air purifiers.

Background technique

Now, with the acceleration of the industrialization process, the air pollution is becoming more and more serious. Many countries have formulated corresponding environmental governance laws and policies, and established various corresponding purification facilities, but the governance effect is not great. There are many harmful gases in outdoor pollution and indoor pollution, such as formaldehyde, hydrogen sulfide and TVOC. In addition to polluting the environment, they are also prone to diseases on the human body, seriously affecting the physical and mental health of the human body, and causing great harm.

Today's large supermarkets, large office buildings, and villas are all equipped with ventilation systems or central air conditioners. The ventilation systems and central air conditioners have strong air circulation capabilities and high energy efficiency. But these ventilation systems and central air conditioners only alternately circulate indoor and outdoor air, which will filter out a small amount of large particles, and have no ability to decompose and purify the air. The air purifiers currently on the market can purify the air, but their scope of application can only be in the closed environment of small spaces. For large closed spaces, they often seem powerless; and their purification capabilities are limited, only one or two The air purification function is low in efficiency; at the same time, the purification materials they use cannot be replaced, which is easy to generate electronic waste, cause secondary pollution, reduce the purification efficiency and sustainable use time of the purifier equipment, and do not conform to the social concept of energy conservation and environmental protection.

Chinese invention patent 2011101189708 discloses an indoor ceiling-mounted air purifier, which consists of a power supply, a mesh inlet, a roof with installation holes, an ultraviolet lamp, a photocatalyst filter, a HEPA filter, an activated carbon filter, a bracket, and a fan blade. , a protective cover, and a motor, which solves the problem of indoor high-concentration dirty air purification. After starting up and running, the dirty air is sucked in from the suction port with primary filter, first sterilized by ultraviolet light and photocatalyst filter, and then passed through the HEPA filter. Capture pollutants with a diameter greater than or equal to 0.03 microns in the air, with a filtration efficiency of 99.9%. Finally, the air passes through activated carbon to absorb odors and harmful gases, and the purified air is sent vertically downwards. This process produces a benign air circulation indoors with high efficiency. Purify the air to achieve the purpose of purifying the air.

Another example is the Chinese invention patent 2004100252085, which discloses a combined air purification and sterilization device, including: particle capture components, ozone-photocatalytic components, water mist spray-air-water separation components, according to the air flow direction, the particle capture components are arranged in At the front, the ozone-photocatalytic component is set behind the particle capture component, and the water mist spray-gas-water separation component is set behind the ozone-photocatalytic component. The three components are independent and parallel, and are closely connected with the air duct around them. All airflow It passes through the particle trapping component, the ozone-photocatalytic component and the water mist spraying-gas-water separation component in turn. The invention combines water mist absorption technology with photocatalysis and ozone technology, uses water mist to absorb remaining organic pollutants and ozone gas, and discharges clean gas. The invention has strong ability of killing bacteria and good effect of removing organic pollutants, and is especially suitable for indoor air purification of a central air-conditioning system.

However, the above-mentioned prior art is not specifically aimed at the treatment of fine particles in the air. Although the water mist spray-air-water separation assembly of Chinese invention patent 2004100252085 has a certain effect, it is only for the treatment of fine particles by water mist spray. The removal effect needs to be further improved.
