摘要:
提出一种基于溶液除湿的消除湿烟羽系统.该系统由烟气冷凝过程和烟气溶液除湿过程构成,利用盐溶液对待处理烟气进行除湿达到消除湿烟羽的技术标准,同时回收待处理烟气自身显热和潜热驱动溶液循环,不需要消耗额外热能,还能够回收烟气中水资源.建立了系统主要部件的数学模型,研究了待处理烟气温度tg,in、相对湿度RHg,in以及室外空气温度ta,amb、相对湿度RHa,amb对排放烟气参数、系统消除湿烟羽性能以及回收水分的影响.结果表明,随着tg,in和RHg,in的增大,消除湿烟羽性能逐渐降低,回收水分逐渐增多;当RHa,amb增大时,排放烟气温度、含湿量以及回收水分几乎无变化,但消除湿烟羽性能会逐渐降低;当ta,amb增大时,排放烟气温度和含湿量逐渐增大,消除湿烟羽性能逐渐增强,回收水分逐渐减少.
Abstract:
A wet plume elimination system based on liquid desiccant dehumidification was proposed, including the flue gas condensation process and the flue gas liquid desiccant dehumidification process. The salt solution was used to dehumidify the flue gas to be treated to meet the technical standard of eliminating the wet plume, and the sensible heat and the latent heat of flue gas were recovered to drive the liquid desiccant cycle. It did not need to consume additional heat and could recover water from the flue gas. Mathematical models of the major components in the system were established to study the effects on key parameters, that are, the flue gas to be treated temperature tg,in, relative humidity RHg,in and the ambient air temperature ta,amb, relative humidity RHa,amb on discharged flue gas parameters, wet plume elimination performance, and recovered water by the system. The result shows that the wet plume elimination performance decreases and the recovered water increases gradually with the increase of tg,in and RHg,in. When RHa,amb increases, the change in the temperature, the moisture content of the discharged gas and the recovered water is not obvious, but the wet plume elimination performance decreases gradually. When ta,amb increases, the temperature and moisture content of the discharged gas and the wet plume elimination performance increase, but the recovered water decreases gradually.
