What factors affect the adsorption effect of activated carbon filters?
What factors affect the adsorption effect of activated carbon filters?I. Specific surface area of filter mediaWhat is the specific surface area? This may be a problem that is not clear to many users. Simply put, it is the sum of the surface area of the particles and the internal pores of 1 gram of activated carbon. If the pores are too small, it will be difficult for the adsorbent to enter; if the pores are too large, the total surface area per unit volume will be reduced, which means that if the specific surface area is reduced, the adsorption capacity of activated carbon will be reduced. II. Influence of external temperature The adsorption capacity of activated carbon is inseparably related to the external temperature change. Within a certain temperature range (for example, between -30 degrees and 40 degrees), the higher the temperature, the faster the adsorption speed of the material, and the better the effect. Under normal circumstances, the molecules in the air will gradually do irregular movement due to the increase in temperature, and their movement will be accelerated, so that they will be absorbed and adsorbed by the activated carbon more quickly. III. The flow rate of air Simply put, the greater the flow rate of indoor air or water, the faster the adsorption rate will be. IV. The pressure of the air Similar to the above, the greater the pressure in the air, the faster the adsorption rate will be. V. Concentration of the harmful gas In addition to the equipment itself, the speed also has a great relationship with the concentration of harmful gases, if the concentration is higher, the adsorption effect will be more obvious. |
