It can be applied to wet ventilation technology.

2. Description of the Related Art Conventionally, an adsorbent regenerating device for improving the regenerating efficiency of an adsorbent regenerating device of a dehumidifying device using an adsorbent to save energy in the regenerating process is disclosed in, for example, Japanese Patent Laid-Open No.
The one reported in Japanese Unexamined Patent Publication No. 222 is known. Hereinafter, this conventional adsorbent regeneration device will be described with reference to the drawings.

FIG. 9 is a cross-sectional view of an essential part of a conventional adsorbent regenerating apparatus according to Japanese Patent Laid-Open No. 5-222. Solid adsorbent 10
1a and 101b are formed into a honeycomb shape, and the adsorbent 101
Heating source 1 consisting of an electric heater between a and the adsorbent 101b
02 is provided. The blower 1 is provided upstream of the adsorbent 1a.
03, and all of these components are surrounded by the air duct 104.

The adsorbent regenerating apparatus having the above structure is
When entering the regeneration process, first, the electric heater 102 operates.
The electric heater 102 turns the air sent by the blower 103 into high-temperature air, and changes the temperature of the adsorbent 1 downstream of the electric heater 102.
01b is heated. On the other hand, the adsorbent 101 a upstream of the electric heater 102 is heated by receiving radiant heat from the electric heater 102.

Adsorbent 101 by the high temperature air and radiant heat
By heating a and 101b, adsorbents 101a and 101b
Moisture inside is desorbed. According to this conventional adsorbent regeneration device, the heating source 102 is arranged between the adsorbent 101a and the adsorbent 101b divided into two, and the adsorbents 101a and 101b divided into two by the heating source 102 are heated. Is configured.

Therefore, as compared with the case of heating the undivided adsorbent, the adsorbents 1a and 1b divided into two are heated more uniformly to remove the moisture in the adsorbents 1a and 1b more uniformly. Can be separated. Therefore, the heat dissipation loss can be reduced and the regeneration efficiency can be improved as compared with the case of heating the undivided adsorbent.

[0007]

As described above, in the conventional adsorbent regenerating apparatus, the adsorbents of the elements are separated into two spaces, that is, the adsorbents 101a and 101b.
The adsorbent 101a and the adsorbent 1 are divided into two parts.
By arranging the heating source 102 in the space between 01b to heat the adsorbents 101a and 101b more uniformly than in the case of heating the undivided adsorbent, the regeneration efficiency is improved. Is.

However, in such a conventional adsorbent regenerating apparatus, since the adsorbent 101a on the upstream side is heated by radiant heat, if the adsorbent 101a is heated to be sufficiently regenerated, the thickness of the adsorbent 101a is reduced. It could not be the same as the adsorbent 101b and could not be so large. Therefore, the thickness of the adsorbent 101a must be thinner than that of the adsorbent 101b in order to sufficiently regenerate it by radiant heat.

Further, since the adsorbent 101b on the downstream side is deprived of the heat of adsorption due to the regeneration, the temperature of the heat source 10 on the side of the air outlet opposite to the side on which the heat source 102 is arranged.
It is easier to fall than the 2 side. Therefore, the adsorbents 101a, 10
It was difficult to uniformly heat the entire 1b, and a more excellent heating method had to be performed in order to increase the regeneration efficiency.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and the adsorption dehumidification that can easily and uniformly heat the entire adsorbent and further improve the regeneration efficiency of the adsorbent. An object is to provide a device and a ventilation device.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. Embodiment 1. 1 and 2 are diagrams showing a configuration of an adsorption dehumidifying device according to a first embodiment of the present invention. FIG. 1 is a sectional top view showing a configuration of the adsorption dehumidifying device, and FIG. 2 shows a configuration of the adsorption dehumidifying device. It is a front view shown. FIG. 3 is a perspective view showing an adsorption dehumidifying element used in the adsorption dehumidifying device shown in FIGS. In FIGS. 1 to 3, 1a and 1b are adsorption dehumidifying elements each divided into two sections in the direction of air flow, and 1c is a passage provided in the adsorption dehumidifying elements 1a and 1b. .

Both regeneration air and adsorption air (dehumidification air) pass through the passage 1c of the adsorption / dehumidification elements 1a and 1b. The adsorption / dehumidification elements 1a and 1b are, for example, those in which silica gel or the like is bonded to an inorganic fiber such as ceramics by a polymerization reaction, and a large number of linear passages 1c through which treated air passes are corrugated throughout. It has a rectangular parallelepiped shape or a cubic shape in which it is distributed.

Reference numeral 16 denotes an adsorption dehumidifying element 1a, 1 which is divided into two.
It is a sheet heater closely wound around the outer periphery of b. The adsorptive dehumidifying element 1 a and the adsorptive dehumidifying element 1 b are divided via the planar heater 16. Sheet heater 1
Various types of 6 can be applied, but in consideration of adhesion, a strip-shaped type having a small thickness and flexibility is preferable. Further, in consideration of uniform heating, the planar heater 16 having a heat generating portion capable of uniformly heating the entire surface is preferable. Reference numeral 17 is a terminal for energizing the planar heater 16.

Regeneration of the adsorption / dehumidification elements 1a, 1b is performed by heating the sheet heater 16 by supplying electricity from the terminal 17. At this time, the planar heater 16 is not wound around the upstream side portions of the adsorption / dehumidification elements 1a and 1b, but the upstream side portion of the planar heater 16 which is not wound around is the planar heater wound around the downstream side. It is heated by heat conduction from the portions of the adsorption / dehumidification elements 1a, 1b heated by 16. Downstream of the adsorption dehumidifying elements 1a, 1b,
It is heated by the sheet heater 16 that is directly wound, and the temperature becomes higher toward the downstream side, resulting in a temperature distribution with good regeneration efficiency.

As described above, in the present embodiment, the planar heater 16 is provided on the outer periphery of the adsorption / dehumidifying elements 1a and 1b divided into two parts.
Since it is configured by closely winding the
The heat can be directly transmitted to the adsorption / dehumidification elements 1a and 1b without passing through the air. Therefore, it is possible to easily and uniformly heat the entire adsorption / dehumidification elements 1a and 1b, as compared with the conventional case where heating is performed via high-temperature air and air by radiant heat. Therefore, the regeneration efficiency of the adsorption / dehumidification elements 1a and 1b can be improved more than ever before.

Further, in the present embodiment, as shown in FIG. 2, when the sheet heater 16 is tightly wound around the outer peripheries of the adsorption / dehumidification elements 1a, 1b, it is not wound around a part on the upstream side, It is wound around the downstream side. This allows
The downstream side of the adsorption / dehumidifying elements 1a and 1b can be heated so that the temperature on the downstream side does not decrease. Therefore,
In the past, when regenerated high temperature air was made to flow from the upstream side of the adsorption / dehumidification element, the problem of desorption heat (such as heat of vaporization of water), which caused the temperature to decrease toward the downstream side and which made regeneration difficult, can be suppressed. it can.

Further, the following effect can be considered by arranging the sheet heater 16 on the downstream side instead of winding it on the upstream side part. Adsorption dehumidification element 1
When adsorbing to a and 1b, it adsorbs from the upstream side of the flow. At this time, the amount of adsorbed water increases on the upstream side of the adsorption / dehumidification elements 1a and 1b, and decreases on the downstream side. In order to desorb, that is, regenerate, the small amount of water on the downstream side, it is desirable that the downstream side of the adsorption / dehumidifying elements 1a and 1b be at a higher temperature than the upstream side. Therefore, according to the present embodiment, it is possible to efficiently desorb the small amount of water on the downstream side.

The heater 2 is also arranged so as to be separated from the adsorption dehumidifying element 1a on the upstream side by a predetermined distance.
The adsorption / dehumidification elements 1a and 1b and the heater 2 are supported by side plates 13 arranged so as to be sandwiched from the surroundings.

During regeneration, the regeneration air is heated to high temperature by energizing the heater 2. Initially, the upstream adsorption / dehumidification element 1a is regenerated, but some of the regenerated air remains at a high temperature, and the bypass hole 1c of the upstream adsorption / dehumidification element 1a is maintained.
