Low temperature plasma air purifiers are products that improve air cleanliness, mainly divided into household, commercial, industrial, and building categories.

Plasma in low-temperature plasma air purifiers is a type of aggregated substance, which is different from the common sense "solid", "liquid", and "gas" three state substances. It is the fourth state of matter, and when its high-energy electrons collide with molecules in the air, a series of elementary physicochemical reactions occur, producing various active free radicals and ecological oxygen during the reaction process, namely atomic oxygen produced by the decomposition of ozone.

The principle of low-temperature plasma air purifier for removing pollutants:

Under the action of an external electric field, a large number of energy carrying electrons generated by dielectric discharge bombard pollutant molecules, causing them to ionize, dissociate, and excite. This then triggers a series of complex physical and chemical reactions, transforming complex large molecule pollutants into simple small molecule substances, or transforming toxic and harmful substances into harmless or low toxicity substances, thereby enabling pollutants to be degraded and removed. Due to the average energy of electrons generated after ionization being 10 eV, controlling the reaction conditions appropriately can make chemical reactions that are generally difficult to achieve or slow in speed very fast.

Low temperature plasma air purifier is suitable for:

Low temperature plasma air purifiers are widely used in home, medical, and industrial fields, with single machine home air purifiers being the mainstream products in the home market. The main function is to remove particulate matter from the air, including allergens, indoor PM2.5, etc. It can also solve the problem of indoor, underground space, and vehicle volatile organic compound air pollution caused by decoration or other reasons. Due to the nature and uncertainty of the release of air pollutants in relatively enclosed spaces, using air purifiers to purify indoor air is recognized as one of the methods for indoor air quality.

Has the following characteristics:

1. Using a packed tower to purify exhaust gas, suitable for the treatment of continuous and intermittent emissions of exhaust gas;

2. The process is simple, and the management, operation, and maintenance are quite convenient and concise, without causing any impact on the production of the workshop;

3. Widely applicable and capable of purifying multiple pollutants simultaneously;

4. Low pressure drop, high operational flexibility, and excellent defogging performance;

5. The tower body can be made of materials such as FRP/PP/PVC according to the actual situation;

6. The packing material adopts a low resistance Ball ring, which can effectively remove odors, harmful substances, etc. from the gas.

7. Our company's waste gas treatment tower adopts a five fold waste gas adsorption filtration purification system. The industrial waste gas treatment design is meticulous, and the waste gas is purified and filtered layer by layer, with good results and a removal rate of over 99%.

Scope of application:

Widely used in the purification treatment of acidic and alkaline waste gases emitted in industries such as chemical, electronic, metallurgical, electroplating, textile (chemical fiber), food, and machinery manufacturing processes. Such as seasoning food, acid making, pickling, electroplating, electrolysis, batteries, etc.

Selection of Low Temperature Plasma Air Purifier:

1. Filtering technology

The main technology for filtering particulate pollutants is HEPA filters. The quality of HEPA filters varies greatly. Although some small filters have high filtration efficiency, they have high resistance, low energy efficiency ratio, and are easy to clog and have a short lifespan. It is generally recommended to use dust containing HEPA filters with electrostatic precipitators. Electrostatic precipitators make non-woven fibers positively and negatively charged, capturing particulate matter in the air. Many HEPA filters claim to have electrostatic precipitators, but due to technical reasons, the electrostatic charge of many filters will decay quickly in a short period of time, resulting in a decrease in filtration efficiency.

You can choose HEPA filters on the market such as 3M electrostatic precipitators, which use the same electrostatic precipitator technology as 3M masks to ensure that the efficiency does not decrease.

2. Pay attention to the applicable area or particulate matter clean air volume (CADR)

The strength of the purification ability of an air purifier is mainly determined by the applicable area and the clean air volume of particulate matter (CADR: the rate of clean air provided), and the relationship between the two is: applicable area=CADR × 0.1. The purification ability for other pollutants should be combined with the applicable area.

3. Energy efficiency ratio and energy efficiency grade

Air purifiers are usually used continuously for a long time, and the energy efficiency ratio is an important indicator for measuring the purification capacity and power consumption of air purifiers, which deserves everyone's attention. The higher the energy efficiency ratio and energy efficiency level, the more energy-efficient and cost-effective the air purifier is.

4. Ozone release amount

Ozone, as a strong oxidant, has the ability to purify, but it is harmful to the human body. There is a mandatory requirement for the amount of ozone released by air purifiers, limited to ≤ 5 × 10-6% (ozone has a fishy odor).
