Abstract
Abstract A rotary dehumidifier is disclosed which divides the heat-exchange process in a slowly rotating drum containing a filler impregnated with hygroscopic agent into a drying region (P) where the air to be treated is dried and a regenerating region where the filler is de-humidified. By recycling the air which has been passed through a portion of the drying region immediately after the regeneration to the regenerating region so as to lower the temperature of the preheated air for regeneration and further by reducing the cooling of the dried and processed air, considerable savings in energy consumption are achieved.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
125 words
A rotary dehumidifier comprising a drum-shaped rotor rotatable around an axis containing a filler impregnated with a hyqrosco p ic agent and which allows air flow in the direction of the axis, the opposing axially spaced faces of said drum-shaped rotor being divided into a drying region defined by a first anqle around said axis for drying the air to be processed and a regenerating region defined by a second angle for regenerating said filler with a preheated gas, characterised in that the rotor is so constructed that the processed air which has passed through a portion of said drying region adjacent to said regenerating region and said preheated gas heated by the atmospheric air are supplied through the whole area of said regenerating region.
Claim 2
Dependent Claim
125 words
A rotary dehumidifier comprising a drum-shaped rotor rotatable around an axis containing a filler impregnated with a hyqrosco p ic agent and which allows air flow in the direction of the axis, the opposing axially spaced faces of said drum-shaped rotor being divided into a drying region defined by a first anqle around said axis for drying the air to be processed and a regenerating region defined by a second angle for regenerating said filler with a preheated gas, characterised in that the rotor is so constructed that the processed air which has passed through a portion of said drying region adjacent to said regenerating region and said preheated gas heated by the atmospheric air are supplied through the whole area of said regenerating region.
Claim 3
Dependent Claim
122 words
A rotary dehumidifier comprising a drum-shaped rotor rotatable around an axis which drum contains a filler impregnated with a hygroscopic aaent and which allows air flow in the direction of the shaft, the opposing faces of said drum-shaped rotor being divided into a drying region defined by the first angle around said axis for drying the air to be processed and a regenerating region defined by the second angle for regenerating said filler with preheated outside air which is characterised in that further non-preheated outside air which has passed through a portion of said drying region adjacent to said regenerating region is mixed with and heated together with sufficient outside air and is supplied through the whole area of said regenerating region.
Claim 4
Dependent Claim
122 words
A rotary dehumidifier comprising a drum-shaped rotor rotatable around an axis which drum contains a filler impregnated with a hygroscopic aaent and which allows air flow in the direction of the shaft, the opposing faces of said drum-shaped rotor being divided into a drying region defined by the first angle around said axis for drying the air to be processed and a regenerating region defined by the second angle for regenerating said filler with preheated outside air which is characterised in that further non-preheated outside air which has passed through a portion of said drying region adjacent to said regenerating region is mixed with and heated together with sufficient outside air and is supplied through the whole area of said regenerating region.
Claim 5
Dependent Claim
120 words
A rotary dehumidifier comprising a drum-shaped rotor rotatable around an axis which drum contains a filler impregnated with a hygroscopic agent and allows the air flow in the direction of the axis, the opposing faces of said drum-shaped rotor being divided into a drying region defined by the first angle around said axis for drying the air to be processed and a reqeneratin q region defined bv the second angle for regenerating said filler with preheated outside air which is characterised in that further non-preheated outside air which has passed through a portion of said drying region adjacent to said regenerating region is mixed with already preheated outside air and is supplied through the whole area of said regenerating region.
Claim 6
Dependent Claim
120 words
A rotary dehumidifier comprising a drum-shaped rotor rotatable around an axis which drum contains a filler impregnated with a hygroscopic agent and allows the air flow in the direction of the axis, the opposing faces of said drum-shaped rotor being divided into a drying region defined by the first angle around said axis for drying the air to be processed and a reqeneratin q region defined bv the second angle for regenerating said filler with preheated outside air which is characterised in that further non-preheated outside air which has passed through a portion of said drying region adjacent to said regenerating region is mixed with already preheated outside air and is supplied through the whole area of said regenerating region.
