Abstract: A method and apparatus for energy-efficient desiccant dehumidification of air or other gases to low humidity levels is disclosed. The method and apparatus includes a desiccant rotor (wheel) having more than one dehumidification zone or sector. Separate dehumidification sectors may be used to dehumidify separate air or gas streams, or they may be used to dehumidify a single air or gas stream by passing it through more than one sector. All or a portion of the discharge air or gas from a dehumidification sector is used for all or a portion of reactivation inlet air or gas prior to heating. The desiccant wheel may include more than one reactivation sector, with separate air or gas sources for each sector. The desiccant wheel may include a purge sector between the reactivation and dehumidification sectors to improve the thermal efficiency of the dehumidification process.
Abstract translation: 公开了一种将空气或其它气体降低到低湿度水平的能量干燥剂除湿方法和装置。 该方法和装置包括具有多于一个除湿区或扇区的干燥剂转子（轮）。 单独的除湿部分可以用于对单独的空气或气流进行除湿，或者它们可以用于通过将单个空气或气体流通过多于一个扇区来除湿单个空气或气体流。 来自除湿部分的排放空气或气体的全部或一部分在加热之前用于全部或一部分再活化的入口空气或气体。 干燥剂轮可以包括多于一个再活化部分，每个扇区具有单独的空气或气体源。 干燥剂轮可以包括在再活化和除湿部分之间的净化扇区，以提高除湿过程的热效率。
