采用吸收塔-汽提塔系统，研究在除湿过程中，使用含有95%三甘醇（TEG）和40%氯化锂（LiCl）的水溶液去除选定的室内空气污染物。吸收系统装有5/8英寸的聚丙烯弹性环，其表面与体积比为104 ft2/ft3（342 m2/m3），能够处理氯化锂水溶液的空气流量，其范围为0.934至1.874 kg/m2（0.192至0.385 lb/ft2），液体流量为8.67至15.18 kg/m2（1.78至3.12 lb/ft2）。为了TEG- 在水溶液中，空气流速范围为0.836至1.338 kg/m2（0.172至0.275 lb/ft2），液体流速范围为5.84至10.85 kg/m2（1.20至2.23 lb/ft2）。讨论了使用这两种溶液去除甲醛、甲苯、二氧化碳和1,1,1-三氯乙烷。传质系数是在广泛的淹水条件下测量的。根据50%溢流时的传质系数计算得出的传质单元高度，对于氯化锂溶液为0.36m，对于三甘醇溶液为0.14m。氯化锂溶液的柱效在65%到70%之间，三甘醇溶液的柱效在90%到95%之间。 关键词:空气污染，室内，污染物，除湿，污染物，甲醛，二氧化碳，氯化锂，空气流量，吸收率，干燥剂，比较。单位:双引文:研讨会，ASHRAE交易1993，第99卷，pt。1.

An absorber-stripper system was used to study the removal of selected indoor air pollutants during the dehumidification process, using aqueous solutions that contained 95% triethylene glycol (TEG) and 40% lithium chloride (LiCl). The absorption system, which was packed with 5/8-in polypropylene flexi rings that had a surface-to-volume ratio of 104 ft2/ft3(342 m2/m3), was able to handle air flow rates that ranged from 0.934 to 1.874 kg/m2•s (0.192 to 0.385 lb/ft2•s) and liquid flow rates that ranged from 8.67 to 15.18 kg/m2•s (1.78 to 3.12 lb/ft2•s) for the LiCl-water solution. For the TEG-water solution, the air flow rates ranged from 0.836 to 1.338 kg/m2•s (0.172 to 0.275 lb/ft2•s), and the liquid flow rates ranged from 5.84 to 10.85 kg/m2•s (1.20 to 2.23 lb/ft2•s). The removal of formaldehyde, toluene, carbon dioxide, and 1,1,1-trichloroethane using these two solutions is discussed. The mass transfer coefficient was measured over a wide range of flooding conditions. The heights of transfer units calculated from mass transfer coefficients at 50% flooding are 0.36m for the LiCl solution and 0.14m for the TEG solution. The column efficiencies ranged from about 65% to 70% for the LiCl solution and from 90 to 95% for the TEG solution.KEYWORDS: air pollution, indoor, contaminants, dehumidifying, contaminants, formaldehyde, carbon dioxide, lithium chloride, air flow rate, absorptivity, desiccants, comparing.Units: Dual
