Method of preparing activated carbon for filter using biomass and method of preparing filter using the same

摘要

The present invention relates to a method for producing activated carbon using biomass and a filter manufacturing method using the same, and more particularly, to a method for producing active carbon using biomass, which comprises: (1) preparing a raw material by pulverizing a biomass and removing impurities of the pulverized biomass powder; (2) a chemical treatment step of mixing an alkali aqueous solution into the biomass powder and then removing moisture from the mixed slurry; (3) an activating treatment step of introducing the biomass mixed powder obtained in the above (2) into a heating furnace and then activating the specific surface area and pores of the heat treatment furnace; And (4) washing the biomass active powder obtained in (3) to remove metal components and then drying to obtain activated carbon powder. (5) (6) The purified supernatant obtained in (5) above and the activated carbon powder obtained in (4) above are mixed with a binder and a fiber-forming resin to obtain a purified supernatant, The present invention also provides a method for producing an activated carbon filter using biomass, which comprises spinning and then spinning and producing the filter. The activated carbon filter manufactured according to the present invention is excellent in adsorption efficiency to fine particles, excellent in odor removal efficiency, and excellent in inhibiting effect on bacterial growth, and is therefore suitable for use in filters for air purification and water purification. Therefore, the activated carbon filter obtained according to the present invention is suitable for use as an air purifying filter, a medium filter, a HEPA filter, a deodorizing filter, a water purification filter, a carbonwound filter and a prefilter.
