DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry humidifier using a solid adsorbent.

[0002]

2. Description of the Related Art A conventional dry humidifier, for example, a rotary dry humidifier, can be rotated by providing a cylindrical solid adsorbent in an annular casing as described in JP-A-63-286634. The inside of the casing is divided into an adsorbing section and a desorbing section, and the air outside the room is blown to the adsorbing section to adsorb the water to the solid adsorbent. When the room is humidified, the solid adsorbent adsorbing the water is desorbed. The air in the room is heated to the desorbing unit while being rotated, and the air is circulated, and the humid air containing the water desorbed from the solid adsorbent is blown into the room and humidified.

FIG. 10 schematically shows the function of a rotary dry humidifier described in JP-A-63-286634, in which a solid adsorbent made of honeycomb silica gel containing lithium chloride is contained. The suction rotor 1 is provided in an annular casing (not shown) made of resin or metal. The inside of the casing is also separated by a partition 2 into an adsorbing section 3 and a desorbing section 4, and the adsorbing rotor 1 is slowly rotated by a drive motor 5 having a rotating mechanism such as a belt to adsorb the solid adsorbent inside the adsorbing rotor 1. It moves from the part 3 to the desorption part 4 and from the desorption part 4 to the adsorption part 3.

When the suction blower 6 is driven to draw outdoor air into the suction section 3, moisture in the outdoor air is adsorbed by the solid adsorbent. When it is desired to humidify the indoor air, the suction rotor 1
To move the solid adsorbent of the adsorption section 3 to the desorption section 4,
When the desorption blower 7 is driven and sucked into the desorption section 4 while the indoor air is heated by the heater 8, the moisture of the outdoor air adsorbed by the solid adsorbent is desorbed and discharged into the room. If this operation is performed while slowly rotating the adsorption rotor 1 by the drive motor 5, the moisture in the outdoor air continues to humidify the indoor air via the solid adsorbent.

[0005]

However, when this dry humidifier is installed outdoors, it is necessary to draw indoor air into the humidifier or discharge and circulate the humidified air into the room. It is necessary to provide an air duct in
In order to reduce the pressure loss when circulating indoor air, the air duct needs to be relatively large, and the size of the blower is also large, and the size of the device is large. In addition, noise is generated when air is circulated in the air duct. Further, the heated and humidified humid air needs to be covered with a heat insulating material in order to cause dew condensation inside the air duct due to a temperature difference between the inside and outside of the air duct.

[0006] It is an object of the present invention to provide a dry humidifier that solves these problems.

[0007]

According to the dry humidifying apparatus of the present invention, an adsorption rotor containing a solid adsorbent is provided in an annular casing made of resin or metal, and the interior of the casing is separated from an adsorption section and a desorption section by partition walls. A drive motor having a rotating mechanism such as a belt for rotating the adsorption rotor, an adsorption blower for sucking outdoor air into the adsorption section, and an outdoor blower for adsorbing outdoor moisture adsorbed by the solid adsorbent. Desorption blower and heater for inhaling and heating outdoor air into the desorption part for desorption with air, and also for cooling and dew condensation of moist air containing desorbed water to obtain dew condensation water The apparatus is provided with a dew condenser, a water pipe for introducing dew water into the room, an evaporating dish for evaporating the dew water introduced as humidifying means in the room, and an evaporation heater.

[0008]

According to the present invention, when the suction blower is driven to suck outdoor air into the suction section, the moisture of the outdoor air is adsorbed by the solid adsorbent of the suction rotor. When the desorption blower is driven and the outdoor air is sucked into the desorption part while being heated by the heater for heating, the moisture of the solid adsorbent is desorbed. Furthermore, the moist air containing the desorbed water flows into the dew condenser and forms dew at the dew point where it is cooled by the cooling fan. . Since the evaporating dish is heated by the evaporating heater, the dew water flowing down evaporates there and humidifies the room. Since these operations are performed while the suction rotor is slowly rotated by the drive motor, the indoor air is continuously humidified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a dry humidifier according to the present invention will be described below with reference to FIGS. FIG. 1 shows a schematic configuration of functions of a dry humidifier of the present invention (not shown).
200m outside diameter inside resin or metal casing
m, 100 mm thick cylindrical honeycomb ceramic with silica gel as a solid adsorbent in a volume ratio of 5%.
0%, silica gel 50% supported and adsorbed rotor 1
And

A partition wall 2 for separating an adsorption section 3 and a desorption section 4
Is based on the relationship between the adsorption efficiency depending on the temperature of the outdoor air and the desorption efficiency depending on the rising temperature of the indoor air heated for desorption. Is set to 1. Since the suction rotor 1 is cylindrical, the partition wall 2 opens at an angle of 90 ° with respect to the rotation axis of the suction rotor 1 to partition the inside of the casing.

When outdoor air with a flow rate of 81 m ³ / h is sucked into the adsorption section 3 by the adsorption blower 6, the moisture of the outdoor air is mainly adsorbed by the solid adsorbent silica gel. When the adsorbed rotor 1 is rotated and moved to the desorption section 4, the adsorbed moisture removes air outside the room by a desorption blower 7 by a heater 8 for heating by about 1 mm.
When sucked into the desorption section 4 at a flow rate of 27 m ³ / h while heating to 00 ° C., the water content of the silica gel is desorbed and the outdoor air is reduced to about 5
It becomes 0 ° C moist air. Next, since the humid air flows into the condenser 9, the moisture in the humid air is condensed and removed, and the remaining air is discharged outside the room. The dew condensation water of the dew condenser 9 drops and flows into the water passage pipe 10 and is introduced into the room using the height difference, flows down to the evaporating dish 11 and is heated by the evaporating heater 12 to evaporate and humidify the room.

The humid air is supplied from the desorption section 4 by the desorption blower 7 shown in FIG.
Then, the moisture in the humid air is condensed in the dew point 93 to form dew water, and the humid air is dehumidified and discharged outside the room. The condensed water is dropped onto the water pipe 10 and flows down from the outside to the indoor evaporation dish 11 through the water pipe 10 due to the difference in height. Since the evaporating dish 11 is heated by the evaporating heater 12, the condensed water evaporates and humidifies the room.

The operation described above is performed by driving the suction rotor 1 by one hour per one hour by the drive motor 5 having a rotation drive mechanism such as a belt.
Since it is performed while rotating at a slow rotation speed of 2 to 14 rotations, the desorbed water obtained by desorbing and absorbing moisture from the outdoor air and heating the outdoor air is introduced into the room and evaporated. Humidification is performed continuously.

FIG. 3 is an explanatory view of the dew-condensing portion of the dew-condenser when the dew-condensing portion 93 is viewed from the conduit along the cross section in the direction of the pipe axis around the dew-condensing portion 93.

In addition, a dew-condensing portion 93 having a cooling fin built therein is provided in a moist air passage 92 in a pipe of a cooling air blowing passage 96. Cooled by air, the dew condensation water flows into the water pipe 10.

FIG. 6 is a cross-sectional view of the periphery of the dew portion 93 in this system, in which a spiral fin 97 and a dew condensation water receiving groove 98 for collecting and flowing dew water are provided inside the humid air passage 92. As a result, a rotating flow is generated in the humid air, the residence time is lengthened, and dew water can be obtained more efficiently.
