Sealing plate liner 80 is formed as mountain type, and its width is radially along with sealing plate 10a side upward and shorten.Thus, sealing plate liner 80 can strain, makes its length variations in the axial direction of adsorber rotor 10.Especially in the present embodiment, the end of the sealing plate 10a side of top easily produces strain than the end of below.
(3) dehumidifying of dehydrating unit 100 action
Dehydrating unit 100, in the situation that starting dehumidifying action, drives by the fan motor 55 by sharing, and drives supply fan 33 to rotate via supply fan driving shaft 33a, and drives regeneration fan 43 to rotate via regeneration fan driving shaft 43a.
Thus, being taken into mouth 51 from the processed air TA of object space by the processed air of shell 50 is taken in air inlet stream 30.And, be taken into mouth 53 with air OA by the regeneration air of shell 50 from the regeneration outside room and be taken in regeneration stream 40.
At this, by being driven by CD-ROM drive motor 11, adsorber rotor 10 rotates, and the each several part of adsorber rotor 10 alternately passes through between absorption position X and reproduction position Y.
And heater 8 heats, the temperature rise of the regeneration air passing through in the upstream side regeneration stream 41 of regeneration stream 40 thus.
Under this state, the processed air TA being taken in the upstream side air inlet stream 31 of air inlet stream 30 is removed dust by processed air cleaner 61, is then directed into the absorption position X of adsorber rotor 10.When the moisture of this processed air TA is positioned at the part of absorption position X in by adsorber rotor 10, be configured the silica gel absorption of adsorber rotor 10.Thus, the dehumidified dry air of the absorption position X in adsorber rotor 10 after passing through flows in downstream air inlet stream 32.
At this, the dry air flowing through in downstream air inlet stream 32 is mainly provided in object space by the dry air conveying end 52 of shell 50, and the humidity of object space is declined.And a part for the dry air flowing through in downstream air inlet stream 32 is carried out branch, and is transported to upstream side inlet plenum 35 by dry air connecting path 34, the humidity of upstream side inlet plenum 35 is declined.
In addition, the regeneration air OA being taken in the upstream side regeneration stream 41 of regeneration stream 40 uses air cleaner 62 to be removed dust by regeneration, is then heated via heater 8, then is directed into the reproduction position Y of adsorber rotor 10.When this regeneration air OA that becomes high temperature is positioned at the part of reproduction position Y in by adsorber rotor 10, the moisture of the silica gel absorption that is configured adsorber rotor 10 is departed from, make this partial regeneration of adsorber rotor 10.And the regeneration that the humidity after the reproduction position Y in adsorber rotor 10 passes through increases is processed rear air and is flowed in downstream regeneration stream 42.The regeneration of flowing through in downstream regeneration stream 42 is like this processed rear air and is discharged to outside room by the exhaust outlet 54 of shell 50 as discharging air EA.
The part of regenerating according to the above adsorber rotor 10, moves to reproduction position X again by the rotation of adsorber rotor 10 self, is again adsorbed on the moisture of the processed air TA flowing through in air inlet stream 30.Like this, can when being regenerated, adsorber rotor 10 provide dry air to object space continuously.
(4) feature
(4-1)
In the dehydrating unit 100 with structure as in this embodiment, in the time wanting to improve the speed of the air stream that passes through adsorber rotor 10, increase at pressure between upstream side air inlet stream 31 and adsorber rotor 10 or between upstream side regeneration stream 41 and adsorber rotor 10, think from generation leakage between sliding surface and each stream.
On the other hand, in the dehydrating unit 100 of present embodiment, be configured to, what supply fan 33 produced produce towards the air-flow of the processed air TA of downstream air inlet stream 32 and regeneration fan 43 from upstream side air inlet stream 31 from upstream side regeneration stream 41 towards the air-flow of the regeneration air OA of downstream regeneration stream 42 in the axial direction from same side by adsorber rotor 10.
Therefore, want the processed air TA from leaking between upstream side air inlet stream 31 and adsorber rotor 10 and want the regeneration air OA from leaking between upstream side regeneration stream 41 and adsorber rotor 10 mutually to collide, be difficult for producing from flowing between upstream side regeneration stream 41 and adsorber rotor 10 between upstream side air inlet stream 31 and adsorber rotor 10, be also difficult for producing its reciprocal flowing.
Thus, can be suppressed at the not dehumidified air flowing through in regeneration stream 40 and sneak in processed air TA, improve the efficiency of dehumidifying.
