An activated carbon folding filter is also called activated carbon fiber filter. It is widely used in chemical, pharmaceutical, food, entertainment venues, places that need to purify the air, and the recovery of harmful gases such as benzene, formaldehyde, ammonia, etc. by adsorption and removal of solvents, using activated carbon The felt has a large specific surface area and strong adsorption capacity. It can quickly deal with various harmful gases and effectively clean the air to control the odor.
Activated carbon foldable filter is mainly used to remove gas, odor, and smoke. The removal of odors increases the proportion of room return air, thereby reducing the energy loss of heating and cooling. The specific gravity of the activated carbon filter is up to More than 63% carbon.
Features of activated carbon folding filter:
01 Aluminum profile frame, galvanized frame, and stainless steel can also be used, thickness: 21mm, 25mm, 46mm, 50mm, and other thicknesses.
02Chemical fiber filter material, large dust holding capacity.
03 Filter material: activated carbon felt.
04The iron wire protection net is treated with multiple layers of pickling and baking paint on the surface to prevent rust, and can well fix the filter structure to ensure that the filter is not deformed during use and has a large dust holding capacity.
The use of activated carbon folding filter
Remove dust, smoke, odor, and volatile organic pollutants benzene, formaldehyde, ammonia, etc.
Applicable occasions of activated carbon folding filter
Airport terminal, chip factory, museum, library, film factory, sewage treatment plant, etc.
Structure performance of activated carbon pleated filter
The larger external surface area speeds up the narrow pore size distribution during the adsorption and desorption process, and the pore size is relatively uniform.
Description of adsorption characteristics of activated carbon pleated filter
1. Large adsorption capacity
Activated carbon fiber has a developed microporous structure. Activated carbon fiber has a large adsorption capacity for organic compound vapor, and also has better performance for some malodorous substances, such as n-butyl mercaptan. It also has good adsorption capacity for inorganic gases such as NO, NO2, SO2, H2S, NH3, CO, CO2, HF, SiF4, etc. The adsorption capacity of inorganic compounds, dyes, benzoic acid, and other organic compounds and precious metal ions in aqueous solution is also higher than that of granular activated carbon. It also has good adsorption capacity for microorganisms and bacteria, such as the isossorption rate for E. coli.
2. Fast adsorption speed
Because the outer surface area of activated carbon fiber is 1-2 orders of magnitude larger than that of granular activated carbon, and many micropores are directly opened on the surface of the fiber, which can directly contact adsorbate molecules, it is 2 to 3 orders of magnitude higher than that of granular activated carbon, and the gas adsorption is general The adsorption equilibrium is reached within tens of seconds or a few minutes, and the adsorption of liquids only needs tens of minutes to reach equilibrium.
3. Fast desorption
Because the fiber is thin, the outer surface is easily heated, so the desorption rate is also very fast.
4. The adsorption capacity for low-concentration adsorbates is particularly excellent
In surface adsorption, the smaller the pore size, the larger the adsorption force field. Since 90% of the activated carbon fiber is microporous, the activated carbon fiber maintains a high adsorption capacity for low-concentration adsorbates, even for ppm-order adsorbates.
5. Thin adsorption layer
Because the activated carbon fiber has a large adsorption capacity, a fast adsorption speed, and can adsorb low-concentration molecules, there will be no "leakage" phenomenon when the activated carbon fiber is used to adsorb and treat exhaust gas or waste liquid, that is, before the adsorption reaches saturation, The effluent concentration is also very low. When adsorbed by granular activated carbon, the effluent concentration is very high. Therefore, when activated carbon fiber is used, the thickness of the adsorption layer can be thinner than that of granular activated carbon.
Other characteristics of activated carbon fiber
The volume density is small, the filtration resistance is small, about one-third of the granular activated carbon, which can be used to adsorb liquid substances with high viscosity and low power consumption. Good air permeability and low-pressure loss
High strength, not easy to pulverize, the adsorption layer will not increase resistance or uneven fluid distribution due to debris deposition and uneven deposition, and will not cause secondary pollution.
With high purity and low impurities, it can be used in food processing and medical and health industries.
