SMOKE AND ODOR CONSUMING APPARATUS OF EXHAUST GAS IN ELECTRIC FURNACE FOR WAX TYPE CALCINATION

摘要

PURPOSE:To prevent the pollution of a catalyst by providing a heater in a dispersion-retention chamber and a porous heat reflection plate thereon and thermally decomposing the particles and tar or the like contained in exhaust gas in a smoke and odor consuming apparatus of exhaust gas in an electric furnace for wax type calcination. CONSTITUTION:The gas flowed from an introduction port 21 is introduced to a conical dispersion-retention chamber 222 as a lower heating chamber and uniformly heated with a heater 24. Then the gas is flowed in an upper heating chamber 223 through the notched part of said heater and heated with a heater. A porous heat reflection plate 26 is provided to the upper part and the gas is passed through the narrow pores 261 of said heat reflection plate and undecomposable substance such as tarry material and soot are caught, thermally decomposed and introduced to a catalyst layer 28. Since the introduced gas is free from undecomposale substance, the catalyst is not contaminated with poison. The gas treated in said catalyst layer is sucked with a fan 361 and discharged.
