Concentration of?dilute lime slurry desulfurization agent.The desulfurization technology had the desulfurization rate,flue gas handling large amount of sorbent utilization, pollution, simple operation and maintenance advantages. This technology was still at an experimental stage, had not been applied to industrial production. Particularly suitable for small and medium-sized coal-fired boiler flue gas desulfurization. For experimental research and teaching presentations designed a spray spouted bedsemi-dry flue gas desulfurization experimental device The device by the spouted bed, heater, cyclone, baghouse, slurry tanks and ancillary equipment The device could be tested?in this experiment the intake air temperature, gas flow, spoutedbed height, Ca/S ratio and other factors on the desulfurization efficiency, and could do the flue gas desulfurization demonstration experiments.
