Duan Z., Huang W., Jia W., Zhang J., 2015, Experimental Investigation and Engineering Application of the Novel WX/U Desulfurization Equipment, Chemical Engineering Transactions, 45, 883-888.
In this paper, a novel wet-flue gas desulfurization absorber including a venturi scrubber unit, a spraying section and a hydro-cyclone unit has been developed and investigated experimentally. A mixture of air and SO2 was used to simulate flue gas and dilute sodium alkali was used as absorbent in the test. Test results indicated that the performance of WX/U desulfurization equipment was good, with the removal efficiency being much higher than that of a venturi scrubber. Furthermore, a full scale WX/U desulfurization equipment which employs dual alkali process has been set up in 2005. The monitoring results from local environmental protection bureau showed that sulfur dioxide of concentration has decreased from 2176 mgNm-3 to 298 mg • Nm-3, while the mass concentration of dust has been decreased from 4027 mg • Nm-3 to39 mg • Nm-3. Overall results indicate that WX/U desulfurization equipment can be used for SO2 absorption and dust collection in coal-fired boilers of either low or medium capacities.
