Embodiment
In order to facilitate the present invention is understood, below in conjunction with the accompanying drawings in the preferred embodiment of the invention that provides the present invention is entered
The detailed description of row.
As shown in Fig. 2 the low dew point rotary wheel dehumidifying unit of the normal temperature of the embodiment of the present invention, including one-level runner heat exchanger 1, two
Level runner heat exchanger 2, preceding surface cooler 3, middle surface cooler 4, rear surface cooling device 5, one-level regenerative heater 6 and secondary regenerator heater
7, one-level runner heat exchanger 1, which is distinguished, sets coagulation moisture absorption area and one-level regeneration desorption area, and two level runner heat exchanger 2 is distinguished and set
Put two stage treatment moisture absorption area, secondary regenerator desorption area and secondary regenerator cooling zone.As one embodiment, two stage treatment moisture absorption
Area, secondary regenerator desorption area and secondary regenerator cooling zone are respectively 60 degree of sector regions, 60 degree of sector regions and 240 degree of fan sections
Domain.Can be according to needed for actual conditions, two stage treatment moisture absorption area is arranged to 30 to 60 degree sector regions, and secondary regenerator desorption area is set
Into 30 to 60 degree sector regions, secondary regenerator cooling zone is arranged to 240 to 300 degree sector regions.
In the present embodiment, fresh air is cooled to 12 degree and the heat exchange heating of coagulation moisture absorption area by preceding surface cooler 3 successively
After to 38 degree with return air formed mixing wind be separated into two-way again, all the way mixing wind pass through successively middle surface cooler 4 be cooled to 12 degree,
Air-supply to arid region, another way mixing wind passes through successively after being cooled again by rear surface cooling device 5 by the heat exchange of two stage treatment moisture absorption area
The heat exchange of secondary regenerator cooling zone is crossed to be warming up to 70 degree, 135 degree are heated to through one-level regenerative heater 6, being desorbed area through secondary regenerator
