【摘要】:燃煤電廠濕法脫硫后排放的煙氣中含有大量水蒸氣,造成大量水資源的浪費(fèi),溶液除濕工藝是水分回收技術(shù)之一。通過絕熱型管式降膜除濕試驗(yàn)臺,采用價(jià)格低廉的CaCl_2溶液為除濕劑,探究了濕煙氣狀態(tài)下溶液濃度、溶液溫度、傳質(zhì)面積及進(jìn)口溫度對除濕性能的影響,試驗(yàn)得到了CaCl_2溶液除濕過程的傳質(zhì)系數(shù),溶液除濕效率遠(yuǎn)高于清水冷凝除濕,為煙氣除濕工藝的選擇和性能預(yù)測提供了參考。
[Abstract]:The coal-fired power plant flue gas wet desulfurization emissions contain a large amount of water vapor, resulting in a large number of waste water, liquid desiccant technology is one of the water recycling technology. Type Falling Film Dehumidifier test rig with adiabatic tube, CaCl_2 solution with low price as desiccant, explores the concentration of the solution under the condition of wet flue gas temperature, influence the mass transfer area and inlet temperature on dehumidification performance, studied the mass transfer coefficient of CaCl_2 solution dehumidification, liquid desiccant efficiency is much higher than the water condensation, which provides a reference for the selection and performance prediction of flue gas dehumidification process.
