主　　题：impinging wall evaporation characteristics temperature and humidity spray drying 

摘      要：Basing on some researchers experimental results,the droplet impinging wall model was modified,and We Number and K Number were adopted to determine the mode of droplet impinging *** simulation results indicated that the mode of impinging droplet is sticking on the wall in Muti-spout *** droplet impinging wall model modified can describe the droplet impinging wall phenomenon accurately in the multistage spouted fluidized flue gas desulfurization *** on the study above,the distributions of temperature and relative humidity in the reactor were *** atomization region,the distribution of temperature exhibits M *** relative humidity exhibitsW*** mass concentration of droplet reduces along axis of the *** to the multi-spouted configuration,droplet concentration increases obviously in the intersection region between the 1st and 2nd stage reaction *** evaporating intensity reaches its peak value in the area of 200 mm away from the sprayer,and droplets are completely evaporated at 1500 mm.
