　　Summary:
　　As China's economic development, food and beverage industry can be developed rapidly, without any treatment of smoke directly into the atmosphere, not only for the city resulted in serious pollution of the atmosphere, but also seriously endangers the health of the residents. Restaurants smoke, vehicle exhaust and various types of noise pollution have Magnetic lifter constituted the three major cities, where residents complained of smoke pollution is increasing. The main contents of this article is to study the use of catalysts that will convert non-toxic fumes of carbon dioxide and water, smoke from the fundamental solution to the problem of pollution.
　　In this paper, ceramic tube (the main component of six aluminum silicate and corundum) as a catalyst carrier, the perovskite structure of rare earth oxides as a catalyst active component, the use of impregnation, prepared ceramic carrier La_ (0.8) Sr_ (0.2) MnO_3 perovskite catalyst. By experiment, design a set of scientific, specific catalytic activity evaluation system, the system includes analog smoke generation system, catalytic reaction system, smoke and http://www.999magnet.com/products/131-magnetic-lifter soot concentration measurement system sampling system; accuracy and feasibility of the proposed catalytic conversion rate is calculated; effects of reaction temperature, calcination temperature, load and other external conditions on the catalyst performance; by XRD, SEM and other analytical tools of the catalyst phase structure and surface morphology. Test results show that the catalyst activity: the kitchen fumes catalytic conversion rate of 80% or more.
