Patent ID: 8366803

Claim:
An air cleaner comprising: at least one filter to purify and treat particulate substances contained in air introduced therein; a regenerative deodorizing filter to adsorb gaseous substances contained in the air introduced therein for purification and treatment; and desorption means to desorb and treat the gaseous substances adsorbed on the regenerative deodorizing filter so that the regenerative deodorizing filter is continuously regenerated, wherein the regenerative deodorizing filter comprises an adsorption section defined by a circular segment having a predetermined circumferential angle, and a desorption section defined by the remaining circular segment other than the adsorption section, and the regenerative deodorizing filter includes a rotary rotor, which is rotatably installed in the regenerative deodorizing filter, wherein the desorption means comprises: a heating unit to heat air supplied to the desorption section of the regenerative deodorizing filter; a heat exchanger through which the air, which is passed through the heating unit and is passed through the desorption section while entraining gaseous substances therein, passes; a desorption air treatment unit to purify and treat gaseous substances contained in the air, which is passed through the heat exchanger and is introduced therein; and, an air transfer unit to enable the air, which is purified and treated by the desorption air treatment unit and is passed through the heat exchanger while exchanging heat with air passed through the desorption section of the regenerative deodorizing filter, to be passed through the heating unit so as to be heat exchanged with air heated by the heating unit, and then to be discharged outside or to be introduced into the regenerative deodorizing filter for retreatment.
