Oxidative-combustion and treatment purifier for lost-foam casting waste gas

The invention discloses an oxidative-combustion and treatment purifier for lost-foam casting waste gas, and belongs to the field of lost-foam casting. A gas inlet chamber, a mixing chamber, a combustion chamber, a combustor and an exhaust hole are arranged in a housing; the gas inlet chamber, the mixing chamber, the combustion chamber and the exhaust hole are sequentially connected; the mixing chamber is a volute casing spiral type air inlet channel; a circular metal net is arranged in the combustion chamber; and a conical flame reflecting device is arranged on the center of the metal net. Thepurifier is simple in structure, is less in investment, is high in purification rate, has waste gas purifying efficiency of 99% or higher, and realizes up-to-standard emission. The oxidative-combustion and treatment purifier eliminates odor emitted by a water-ring type vacuum pump of a lost-foam casting workshop, and solves the tail gas emission problem in a lost-foam casting process. 本发明公开了一种消失模铸造废气氧化燃烧处理净化器，属于消失模铸造领域。壳
