What is a chemical filter?What?Chemical filters are innovative, efficient and energy-saving chemical filter products, mainly used to treat airofNew air purification equipment for malodorous, toxic, harmful and corrosive gases.
Chemical filter removes airofMolecular contaminants. In the field of ventilation and air conditioning, chemical filters use activated carbon as the main filter material.Quality. Typical applications of chemical filters include factories, nuclear industry, airports, environmental protection, museums, automotive air conditioners, etc. Some home appliances also use chemical filter materials.
Chemical filters are different from ordinary filters by removing gas from the airPollutants,Improve indoor air quality(IAQ), To protect people's health and improve product quality, it is widely used in various centralized ventilation systems.
Activated carbonfilter adsorbs airofOdor, remove indoor formaldehyde and other harmful gasesandA variety of filter media, completely solve the pollution problem.
With the development of the industry and the expansion of the city, the concentration of harmful gases around us is increasing. With the advancement of technology and the improvement of life, people's requirements for pure air are also increasing, so the demand for chemical filters is also increasing year by year.
CHEMICAL FILTER SELECTIVELYAbsorptionharmful gas molecules, instead of mechanically removing impurities like ordinary filters.ItThere are many micropores invisible to the naked eye, unit weight materialQualityTotal internal surface area of micropores up700m2/GTo2300m2/G. That is to say, rice grain size activated carbonThe internal surface area of the particles is like the internal wall of the large living room.
Product characteristics of chemical filters
1.FiltrationMaterialAdopt filter core cap type design, good sealing, filter barrel completely without metalMaterialContact.
2.Simple operation.
3.ByPVCIt is made and resistant to chromic acid solution and various acids and alkalis.
4.Chromic acid liquid plating solution, suitable for chemical liquid circulation filtration;
In addition to adsorption, the porous substance itself can become a chemical reaction promoting catalyst, for example, a catalyst for ozone can also be used as a support for other catalysts. in the airThe harmful gas is called "adsorbate", activated carbonIt is called "adsorbent". While the adsorbent grabs the adsorbate, some of the adsorbate escapes. During the use of chemical filtersThe adsorption capacity continues to weaken, and after weakening to a certain extent, the filter is discarded. If only physicalReactionby heating orThe method of steam fumigation can make harmful gases out of activated carbonMake it regenerate.
