１８はフイルターである。 A typical example of a conventional wet dehumidifier with a regeneration function is a dehumidification tower 1 and a regeneration tower 2, as shown in Figure 1.
In the dehumidification tower 1, there is a liquid dispersion device 3 for spraying a moisture absorbing liquid (for example, a lithium chloride solution).
A contactor 4 is attached to the contactor 4, and the outside air (humid air) taken in from the outside air intake 6 by the dehumidification blower 5 comes into contact with this spray of moisture absorption liquid at the contactor 4, and the inside of the contactor 4 is The heat of condensation is removed by the circulating cooling water 7, while the moisture in the humid air is absorbed into the moisture absorbing liquid, while in the regeneration tower 2, a liquid dispersion device 8 for spraying the diluted moisture absorber and a high temperature A heater 9 through which a medium (for example, steam) circulates is attached, and the water in this dilute moisture absorbing liquid is transferred to the outside air 11 taken in by the drive of the regeneration blower 10.
The moisture absorption liquid is regenerated by being transferred by heating. Note that in this Figure 1, 1

り、必ずしも満足な熱回収とはなり得なかつた。 In a wet dehumidifier equipped with such a conventional regeneration function section (heater 9), an external heat source (for example, steam) is required to regenerate the dehumidifying liquid, and reducing the amount of regenerated heat is an issue. For this reason, an attempt has been made to effectively recover the heat retained in the steam drain after passing through the regeneration heater 9, and a drain heat exchanger using the steam drain as a heat medium is disposed in the regeneration air passage. It has been proposed to heat the regeneration air before passing it through. However, in this case, the amount of steam drain generated is a small proportion of the amount of air for regeneration (for example, the amount of steam drain is about 10 to 1.5 t/min for the amount of regeneration air of 900 Nm 3 /min).
hr), the number of passes on the drain side had to be increased, which made the flow path complicated and caused trouble, and it was not always possible to achieve satisfactory heat recovery.

A drain heat exchanger 20 that performs heat exchange between the steam drain and the regenerated liquid to be sprayed toward the regeneration heater 9, and the regenerated liquid passed through the regeneration motor 9 and regenerated and the regeneration heater. A liquid-liquid heat exchanger 21 that performs heat exchange with the regenerated liquid to be sprinkled toward It is characterized by being installed in parallel in the flow pipes of the liquid to be regenerated.

レンの熱回収が達成できる。 Since the drain heat exchanger 20 functions as a liquid-liquid heat exchanger between the liquid to be regenerated and the vapor drain, it is possible to increase the heat transfer rate compared to the case of gas heating of the re-discharged air. Sufficient steam drain heat recovery can be achieved by applying a compact plate heat exchanger with a small thermal area.

The temperature difference between the two liquids becomes large, and a compact plate-type heat exchanger with a small heat transfer area can be used, which means that a small-scale equipment can achieve maximum functionality.

軽減に大きく貢献できる。 Figure 2 shows the new installation of the drain heat exchanger 20 and liquid-liquid heat exchanger 21 on the regeneration side and their connection relationship, and although the dehumidification tower is omitted, the actual system is as shown in Figure 1. A dehumidification tower is connected. Further, members with respective symbols in FIG. 2 represent the same members as those with the same symbols in FIG. 1. In other words, the present invention can be easily modified into an energy-saving type humid dehumidifier with high thermal efficiency by simply adding small equipment to a conventional general-purpose humid dehumidifier, and can greatly contribute to reducing the energy burden.
