摘要
搭建了烟气浓缩实验台,采用新型的"水帘式"喷淋方式,通过单因素实验与正交实验相结合的方法,利用含盐水及实际电厂脱硫废水进行实验研究,探究了烟气体积流量、入口烟温、进水体积流量和盐水电导率等对低温烟气蒸发能力的影响。结果表明:在实验台最佳条件下,单位体积烟气最大蒸发能力为15.33mL/m^3;影响烟气蒸发能力因素由主到次依次为烟气体积流量、入口烟温、进水体积流量;利用"水帘式"喷淋方式时,喷管堵塞风险较小;蒸发产物成分主要为NaCl。
A flue gas concentration test bench was built to conduct the experiments on saline solution and desulfurization wastewater from an actual power plant in the new method of " water curtain" spray by combining the orthogonal experiment with single factor experiment,during which,the effects of following factors on the water evaporation by flue gas were explored,such as the gas flow rate,inlet gas temperature,inlet water flow rate and conductivity of brine on flue gas,etc.Results show that under optimal experimental conditions,the maximum evaporating capacity per unit volume of flue gas is 15.33 mL/m3.The gas flow rate has the most significant influence on the evaporation capacity,followed by the inlet gas temperature and inlet water flow rate.What’s more,there is a low risk of nozzle blockage using the " water curtain" spray method.The main content of evaporation product is found to be NaCl.
