いる。 Liquid dehumidifiers with a dehumidifying liquid regeneration function are widely used in chemical plants and elsewhere. As a problem in constructing and operating such a liquid dehumidifier, there is a problem of material corrosion. That is, unless the device is constructed from high-grade corrosion-resistant materials, corrosion will occur at various locations during use, causing trouble. but,
If a large device were to be constructed entirely of high-grade corrosion-resistant materials, the equipment cost would be enormous, and the device would not be useful in practice. Therefore, there is a strong desire to eliminate the cause of corrosion in liquid dehumidifiers and to take countermeasures against it.

原因にたちかえつて解決したものである。 The present invention was made based on the knowledge that the main cause of corrosion in liquid dehumidifiers is an increase in dissolved oxygen in the dehumidifying liquid due to contact with air in the regeneration function section, and based on this knowledge. Based on this, the corrosion prevention problem is solved by going back to the cause of the problem by cutting off or reducing contact with air in the regeneration function section.

を提供するものである。 That is, the present invention provides an inert gas circulation circuit space that is substantially cut off from outside air in a liquid dehumidifier regeneration device for concentrating a diluted dehumidifying liquid by absorbing moisture in the air in a dehumidifying function section. In this inert gas circulation circuit space, there is a dehumidifying liquid regeneration zone in which the inert gas and the dehumidifying liquid are brought into gas-liquid contact under heating, and a moisture-containing inert gas that has passed through the dehumidifying liquid regenerating zone is cooled. The present invention provides a regeneration device for a liquid dehumidifier, characterized in that a moisture condensation zone is formed to condense moisture.

なつている。 The dehumidifying tower 1 is equipped with a liquid dispersion device 4 and a filling material 5 for spraying a dehumidifying liquid (lithium chloride solution), and the dehumidifying blower 6 drives outside air to be taken in from an intake port 7 through a filter 8. The outside air is brought into gas-liquid contact with the spray of the dehumidifying liquid through the filler 5, and the moisture in the air is absorbed by the dehumidifying liquid and dehumidified.
Dehumidified air is supplied to a desired process via a mist separator 9. At this time, the dehumidifying liquid supplied to the liquid dispersion device 4 is cooled by a cooler 10 and partially circulated by a pump 11.

A portion is sent to the dispersion device 14 of the regeneration tower 2 via the deaerator 12 and the liquid-liquid heat exchanger 13. The regeneration tower 2 of this embodiment constitutes a circuit space isolated from the outside air, and within this circuit space, a regeneration blower 15, the above-mentioned liquid dispersion device 14, a regeneration heater 16, a mist separator 17, and a condenser 18 are installed in order. It has been intervened. and inert gases (e.g., N 2 , Ar, CO 2
etc.) is introduced into this circuit space from the inert gas introduction section 3 provided upstream of the regeneration heater 16, and is used as a medium for removing and conveying moisture in the dehumidifying liquid. That is, the water in the diluted dehumidifying liquid sprinkled from the liquid dispersion device 14 toward the regeneration heater 16 is evaporated by heating in the regeneration heater 16, and this evaporated water is transferred to the regeneration blower 15. Along with the flow of the inert gas driven by the drive, the mist is conveyed through the mist separator 17 to the condenser 18, where it is removed as drain.
This condenser 18 contains cooling water cooled by a cooling tower,
It is possible to use a conventional Finch-Eube heat exchanger, through which cold water or brine, possibly produced in a refrigerator, is passed. The generated condensate is collected in a torrent trap 19 and then discharged from the outside of the system. In order to maintain the amount of inert gas in the regeneration tower 2 at a predetermined value, a pressure regulating valve 21 is attached to the inert gas introduction pipe 20.

ために大きな役割を果たしている。 In this way, in the illustrated embodiment, a dehumidifying liquid regeneration zone is formed in the inert gas circulation circuit space by the regeneration heater 16 and the liquid dispersion device 14 that sprinkles the dehumidifying liquid toward the regeneration heater 16, Further, by arranging the condenser 18 downstream of this dehumidifying liquid regeneration zone, a moisture condensation zone is formed to remove moisture from the moisture-containing inert gas. As a result, the dehumidifying liquid is regenerated in the regeneration tower 2 while the contact with the outside air is cut off. 13 and is returned to the dehumidifying liquid pipe of the dehumidifying tower 1. This liquid-liquid heat exchanger 13 is
The sensible heat of the regenerated liquid concentrated in the regeneration tower 2 is used to heat the dilute pre-regeneration liquid used for regeneration, and the temperature of the dehumidifying liquid in the dehumidifying liquid pipe of the dehumidifying tower 1 is suppressed from increasing. This is useful for reducing the load on the cooler 10, and plays a major role in eliminating waste of thermal energy in the entire device.

価な除湿機を提供するものである。 The device of the present invention avoids the contact of the dehumidifying liquid with the atmosphere in the regeneration function section having a high-temperature section by introducing an inert gas without impairing the regeneration efficiency. This is because the dissolved oxygen in the liquid is lowered by lowering the oxygen partial pressure in the regeneration tower, and even if the dissolved oxygen in the dehumidifying liquid increases in the dehumidification tower, it can be released and removed in the regeneration tower. Compared to conventional dehumidifiers that use atmospheric air in their regeneration function, the present invention provides an inexpensive dehumidifier that is free from corrosion problems by preventing corrosion problems and making it possible to configure the device with inexpensive materials. It is.
