<p>PURPOSE:To obtain a compact air cleaner able to remove any kinds of harmful gases and fine particles perfectly by composing an adsorption part of the cleaner of an active carbon fiber and an ion-exchange fiber. CONSTITUTION:An adsorption part of an air cleaner is composed of an active carbon fiber and an ion-exchange fiber. By this composition, low adsorption function of the active carbon fiber against a basic gas and an acidic gas is compensated by the ion-exchange fiber. Further, in the case of a cationic ion exchange fiber or an anionic ion exchange fiber, the surface of the ion-exchange fiber is changed in (-) and (+), respectively therefore fine particles bearing the opposite electric charge can be removed by electrostatic adsorption and the ion-exchange fiber lowers the work load of a fine particle removing filter or takes over the function of the filter. Or, when an ion-exchange group is introduced into a fine particle removing filter itself by application of radiation graft polymerization, the efficiency of fine particle removal is remarkably increased without enlarging the pressure difference.</p> |
