Heating, and maintains set temperature, and to reach scheduled removal efficiency, through catalysis burning, treated that exhaust gas imports other potteries
Porcelain packed bed, row is into atmosphere after recycling thermal energy, and exhaust temperature is only slightly higher than the temperature before exhaust-gas treatment, and all ceramics are filled out
Fill the circulation step that bed is heated, cooled down, purifying.
Wherein catalyst is loaded on ceramic honeycomb using high-quality noble metal, rare earth and metal oxide makees catalyst, urges
Change resolution ratio up to 95% or more, with very high specific surface area, reaction velocity is larger, the service life is long, decomposition temperature is low, resistance is small, de-
Attached preheating time is short, low energy consumption, mechanical strength is big, wear-resisting, heat shock resistance, catalytic activity and the good feature of thermal stability.Catalysis
Agent is the core component of catalytic decomposition process, and traditional waste gas purification apparatus vent gas treatment low efficiency is urged based on heat accumulating type
Change oxidizing process, needs thus a kind of for house exhaust purification device.
