Experimental studies of SO2 absorption in the sieve-plate wet FGD absorber
Limestone-gypsum wet FGD is the maximum widely applied FGD technology in the world at present,sieveplate absorber is one of the critical tower in wet FGD processes.This article provides a study on the features of flow field distribution,resistance and desulfurization of sieve-plate FGD absorber through Laboratory-scale experimental FGD system.It is shown that the flow field distribution in sieve-plate FGD absorber is homogeneous,the deviation of velocity distribution of flue gas is 0.4-0.58,whereas the standard deviation of empty absorber is 0.99.In comparison with empty absorber,the pressure loss of sieve-plate absorber increased 30-160％,and following the decreasing of void ratio,the pressure loss of sieve-plate absorber has a tendency of increasing.While the void ratio of sieve-plate is decreasing from 44.3％ to 31.5％,the pressure loss increased 16.1-27.6％.The desulfurization efficiency of sieve-plate absorber presents increase first and decrease afterwards following the increasing of void ratio of sieve-plate.In comparison with empty absorber,the desulfurization efficiency increased 822.89％.And under the condition of same sieveplate,the desulfurization efficiency is 3-8％ better when the distribution of sieve-plate pores is in square than that in triangle.
