The invention relates to a method for eliminating wax smoke during firing of ceramic products molded through doping wax. The method is characterized in that the wax smoke is produced by hot dewaxing, cooled by liquid sprinkling, and then discharged after being cooled below 28 DEG C through heat exchange. Wax and smoke in the discharged wax smoke can be simply, conveniently and completely separated, the wax is recovered in the form of solid wax, pollution and odour are eliminated, and the processing method is economic, simple, convenient and reliable. In particular, the wax smoke discharged by dewaxing is first introduced into and burnt in a furnace, therefore, not only can subsequent processing burden be reduced, but also combustion heat energy can be utilized. Wax smoke pollution can be stably eliminated with the method at low cost, the wax can be recovered, and the longstanding unsolved problem of wax pollution in the industry is solved.
