| Municipal solid waste incineration (MSWI) becomes a mainstream of the MSW disposals gradually for its many advantages. But at the same time the byproducts of incineration must be controlled urgently for their increasing pollution.There are two problems of Semi-dry Flue Gas Decontamination Technology: low efficiency of de-acid and low used efficiency of absorbent, and low equipment-running stabilization for conglutination-wall and jam of ash. The two problems' Solving plays a great practically role for Semi-dry Flue Gas Decontamination Technology industrialization and commercialization.In order to settle the problem of low de-acid efficiency and low used efficiency of absorbent, this paper investigates absorbent and ash assimilation-activity-transportation and their appliance in the industrialization experimentation. Based on the results of gas-molecule-free-journey, the mechanism and process of assimilation is probed. With over-heated steam transportation, its approaching saturation is propitious to assimilation under suspend flu condition. For the over-heated steam transportation that P=0.8MPa, T=280°C, it is approached to saturation and advance assimilation of calcium oxide under velocity of flow is 25m/s, mass flux of de-acid-ash and air is that of absorbent 6 times and 1.25times and the ratio of solid to over-heated steam is 13. De-acid-ash is also obtained activity because of breakage of de-acid production layer in the high speed transportation.In order to improve stability of equipment-running, a 27.5m~2 area row-pipeline heat-exchanger is designed. Through heat-exchanger, the system can reduce quantities of atomization water greatly, improve stability of reactor flu field, mitigate jam of de-acid-ash and advance stability of equipment-running.
