The utility mode relates to an incinerator, in particular to an incinerator recycling precious metals from a carbon carrier catalyst containing the precious metals. The incinerator comprises an incinerator frame (1), an incinerator body (2), a blower device (3), an exhaust pipe (4) and a dust collection tower (5), wherein the incinerator frame (1) is connected with the upper part of the incinerator body (2); incinerator doors (10) are arranged on two sides of the incinerator body (2); the blower device (3) is arranged below the incinerator body (2); one end of the exhaust pipe (4) is communicated with the incinerator body (2), and the other end of the exhaust pipe (4) is connected to a recycling pipeline (14); a baffle (17) is arranged in the recycling pipeline (14); one end, at which a sprayer (18) is arranged, of a pumping pipe (16) is connected to the recycling pipeline (14), and the other end of the pumping pipe (16) is accessed to a water outlet of a pumper (15); and a water inlet of the pumper (15) is communicated with a pool (13). The incinerator is high in safety, long in service life and low in cost, and realizes dust recycling.
