Ceramic kiln in the use of the process of high energy consumption, high resource consumption, serious environmental pollution and other problems are the current ceramic industry development of serious problems.Kiln combustion exhaust gas pollution types mainly include: SO2, NOx, CO, particulate matter, lead, cadmium, nickel and its compounds, fluoride and chloride and so on, and the traditional kiln direct emissions into the atmosphere, causing serious pollution to the environment, the need to have reliable purification treatment devices to meet emissions requirements, but the original purification plant purification effect is poor, process complex aspects of problems.This paper introduces a new porous ceramic purification device to improve the electric kiln exhaust gas purification to improve the catalytic conversion of CO, NOX, SO2 desulfurization and particulate matter purification.
