What is the difference between vapor phase purification and activated carbon purification of general

Activated carbon is a good adsorption material, black porous solid carbonaceous, mainly divided into coconut shell charcoal, fruit shell charcoal, wood.

Charcoal, coal-based charcoal. The main component is carbon, and contains small amounts of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. The specific surface area of ordinary activated carbon.

Between 500 and 1700m g. It has strong adsorption performance and is an industrial adsorbent with a wide range of uses. Gas masks.

It is used to filter gases, industrially used to decolorize and purify solutions, and medically used to absorb toxins, bacteria or gases in the gastrointestinal tract.

The vapor phase purification material of general air is a mixed material, which has the function of adsorption + absorption, and like activated carbon, it can remove harmful gases.

The body is adsorbed on the filter material, but after a long period of adsorption, with the increase of temperature and wind speed, the adsorbed pollutants are possible.

It is free to go out, so the filter material should be replaced frequently to avoid adsorption saturation. , while the vapor phase purification material will be adsorbed at the same time.

The adsorbed harmful gases carry out chemical reactions, absorb the harmful gases into the purification**, and operate in the state of adsorption + absorption, which can achieve the purpose of continuously treating fresh air.

GA offers a wide range of chemisorption** for continuous decontamination of corrosive, odorous and toxic contaminants in commercial and industrial environments. Depending on the contamination, GA's chemical filters will use different processes to remove unwanted gases from the polluted air. More precisely, GA employs four main removal mechanisms to eliminate chemical pollutants from the air: adsorption, absorption, chemisorption, and catalysis.

It can play a purifying role, if the house feels that it needs to be cleaned, and the air is not fresh, you can use activated carbon.

It can still play a purifying role, activated carbon has an adsorption effect, so you can use it more to purify the air.

Activated carbon does have a strong adsorption effect and can purify indoor air, but the most important thing is to ventilate.

Bamboo charcoal uses its own air to adsorb toxic substances in the room, and then plays a role in purifying the air.

Activated carbon is a general term for carbon materials prepared by pyrolysis and activation of carbon-containing raw materials such as wood, coal and petroleum coke, which have developed pore structure, large specific surface area and rich surface chemical groups, and strong specific adsorption capacity. It is usually a porous amorphous carbon in powder or granular form with strong adsorption capacity. Generally, people use activated carbon to remove indoor odors and fresh air.

There are also those who are skeptical. Activated carbon does purify the air, but there are a number of limitations. Here's why activated carbon can really purify indoor air.

Indoor air purification, activated carbon can play a certain effect, but it cannot be completely relied on.

It still has a little effect, but remember to replace it in time, because the activated carbon will be released again when it is full.

It does have this effect, and the use time of adsorption activated carbon after home decoration is best controlled within 30 days, and it must be replaced in time.

Yes, activated carbon is a porous structure, which can effectively adsorb toxic substances in the air and can be used a lot.

Not all activated charcoal can be used on activated carbon.

Only modified activated carbon can adsorb and remove chemically harmful gases. In countries with advanced activated carbon finishing and modification technology in the world, such as Canada, different formulas are derived from different modification technologies, so as to achieve the purpose of removing different chemical harmful gases.

In addition, activated carbon for different purposes is used to adsorb different kinds of pollutants. For example, activated carbon for water purification cannot be used to purify toxic and harmful gases in indoor air, in other words, activated carbon for water purification cannot be used on air purifiers.

Because the micropore diameter of the activated carbon used to purify the air must be slightly larger than the diameter of the molecules of toxic and harmful gases, in order to have the adsorption capacity of toxic and harmful gases. The activated carbon used for water purification is mainly used to adsorb impurities and toxic and harmful substances in water, most of which remain in the water in the form of solid or liquid, and the diameter of their particles or molecules is hundreds or even thousands of times larger than the diameter of gas molecules. The micropores of activated carbon for water purification are designed to adsorb these pollutants in water.

Therefore, because there are many differences between the activated carbon used for water purification and the activated carbon used for air purification in the internal microporous structure and structure, the activated carbon used for water purification cannot be used to purify toxic and harmful gases in the indoor air.

In addition, air purifiers like Allerair are not simply using activated carbon technology. Rather, it is a filter material based on activated carbon finishing and modification technology, combined with a variety of medical and industrial clean air core technologies, and added special adsorbents and stabilizers developed by Allerair Industries. Allerair's anti-virus filter (activated carbon filter) is completely different from ordinary activated carbon in terms of internal structure, micropore diameter, adsorption performance, etc., and its purification function for chemically harmful gases is far from that of ordinary activated carbon.

If you use it purely at home, you can buy a home air purifier, which is better if the air volume is larger, generally 20

For a square meter room, you need to buy an air purifier with a volume of 300 air, at least 250 or more. If you are newly renovated in your house, you can even buy a fresh air purifier when the smog is severe.

You can enjoy fresh and clean air at home without opening doors and windows. There are still many air purifier brands on the market, and the better ones are: Yixin, Yadu, Air-Fi, Philips, Sharp and so on.

It is better to buy physical filtration rather than by ionization discharge filtration, in addition, air purifiers generally have activated carbon adsorption, photocatalyst decomposition of formaldehyde, negative ions to release fresh air.

Functional.

At present, the mainstream technology of air purifiers on the market is the physical filtration technology based on activated carbon technology. So what are the types of activated carbon and what are their uses?

Activated carbon is a kind of microcrystalline carbon material made of carbon-containing materials with black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity, and is a commonly used adsorbent, catalyst or catalyst carrier.

Activated carbon can be divided into wood activated carbon, animal bone activated carbon, mineral raw material activated carbon, synthetic resin activated carbon, rubber plastic activated carbon, recycled activated carbon, etc.; Activated carbon can be divided into powder, granular, irregular granular, cylindrical, spherical and fibrous according to its appearance.

The application of activated carbon is extremely wide, and its use involves almost all national economic sectors and people's daily life, such as water purification, ** extraction, sugar solution decolorization, drug injection refining, blood purification, air purification, human safety protection, etc.

So how does activated carbon for air purification adsorb toxic and harmful gases in the air?

The activated carbon used to purify the air has a well-developed pore structure and rich microporous structure, these microporous tissues have a strong adsorption force field, when the toxic and harmful gases in the air are in contact with the activated carbon, the activated carbon micropores have a strong adsorption force field, and can adsorb the molecules of toxic gases and harmful bodies into the micropores.

When using activated carbon to purify the air, in order to give full play to the effect of activated carbon, people often force the air that needs to be purified, through the filter element device made of activated carbon, so that the polluted air can fully contact with the activated carbon, and the well-developed micropores inside the activated carbon can quickly, completely and thoroughly adsorb the toxic and harmful gases in the air, so as to achieve the purpose of purifying the air and protecting the safety of the human body. For example, gas masks and some high-efficiency air purifiers are designed and manufactured using this principle.

The activated carbon technology of AllerAir air purifier in Canada is second to none in the world, not only the dosage is sufficient, the adsorption performance is strong, and the allerair air purifier uses military-grade high-quality granular activated carbon, and adds a unique catalyst, supplemented by a strong fan and reasonable sealing structure, its purification effect is excellent.
