Honeycomb Activated Carbon Filter - Price of Plate Activated Carbon Filter

Tianjin Klien Environmental Protection Technology Co., LtdHoneycomb shaped activated carbon filter-Plate type activated carbon filters use aluminum honeycomb (or paper honeycomb, plastic honeycomb) with through-hole structure as the carrier, and fill the through-hole with fruit shell charcoal or coconut shell charcoal, which is currently a commonly used method of using activated carbon in air filtration. Activated carbon contains a large number of micropores, with a huge specific surface area and super strong adsorption function, which can instantly and strongly remove various odors such as smoke, formaldehyde, ammonia, carbon monoxide, benzene, etc. indoors. The non methane total hydrocarbons in general industrial exhaust require a plate filter with aluminum honeycomb panels, with a thickness of about 45mm. The honeycomb shaped activated carbon filter commonly used in air purifiers is generally 20mm thick, with plastic honeycomb and paper frame packaging. So what about the performance of this filter? Today, the editor will talk about data to give everyone a clear understanding.

According to the standards GB/T18801-2008 "Air Purifiers" and GBT18883-2002 "Indoor Air Quality Standards", we can remove over 90% of harmful gas pollutants in the test room at a rate of 30m ³ per hour.
Experimental object: Specification parameters of honeycomb activated carbon filter: humidity: ≤ 2.0%, hardness: ≥ 95, surface density/bulk density: 30lbs/ft3=(0.48g/cc) ± 0.5%, carbon dioxide content: ≤ 20%, ash content: ≤ 8%, particle size: 2.0-4.0mm.
The experimental results are:

The honeycomb activated carbon plate has the following filtration performance for pollutant gases:

Benzene: Coconut shell activated carbon plate ≥ 90% · h-1, columnar activated carbon ≥ 78% · h

Toluene: Coconut shell activated carbon plate ≥ 82% · h-1, columnar activated carbon ≥ 73% · h

Formaldehyde: Coconut shell activated carbon plate ≥ 70% · h-1, columnar activated carbon ≥ 60% · h

Chlorine gas: Coconut shell activated carbon plate ≥ 73% · h-1, columnar activated carbon ≥ 62% · h

If we want to achieve this effect, we need to pay attention to controlling the wind speed, because if the flow rate is too fast, the adsorption time of activated carbon will be too long, and the purification effect will definitely not be ideal. Generally, the air flow rate range is from 25CFM (42.5m3/hr) to 100000CFM (169920m3/hr), and the flow rate range is from 60FPM to 500FPM (0.30 to 2.54m/s). Service life: To ensure the filtration efficiency of the filtration system, ZF honeycomb activated carbon plates can be tested regularly to determine the filter medium life and maintenance time. The service life of ordinary home environments is not less than 8 months. We suggest replacing two pieces of activated carbon filter when used in furniture environment. The replaced activated carbon filter can restore a certain adsorption capacity after being exposed to sunlight.
