本発明は、比較的低湿度の空気を必要とする工場、研究
所等に利用される吸着剤を利用した圧縮空気除湿装置に
関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a compressed air dehumidification device using an adsorbent, which is used in factories, research institutes, etc. that require air with relatively low humidity. .
（従 来 技 術）
従来の吸着剤を利用した圧縮空気除湿装置としては、第
４図乃至第７図示すようなタイプのものが知られている
。(Prior Art) As a conventional compressed air dehumidifying device using an adsorbent, the types shown in FIGS. 4 to 7 are known.

る。What is shown in FIG. 4 is an adsorption tower 4 filled with adsorbent.
, 5, the three-way valve 1 connected to the air inlet of the adsorption towers 4, 5, and the air outlet of the adsorption towers 4, 5 connected to the solenoid valve 8, respectively.
．． The adsorption towers 4 and 5 are connected to the outside through an orifice 6 and an orifice 6.
この装置の場合、低露点（−７０″Ｃ）の圧縮乾燥空気
を得ようとすると、パージ量（電磁弁２，３から放出す
る空気量）が多くなりパージ率が１５〜３０％とニアロ
スが非常に多いといった不都合があった。In the case of this device, when trying to obtain compressed dry air with a low dew point (-70"C), the purge amount (the amount of air released from the solenoid valves 2 and 3) increases and the purge rate is 15 to 30%, resulting in near loss. The problem was that there were too many.

合があった。However, this device has a low dew point (-70°C).
When trying to obtain compressed air (below), one of two adsorption towers filled with adsorbent such as zeolite is used to dry the compressed air, while a blower 14 is installed in the other adsorption tower to pass hot air through. The moisture in the adsorbent is evaporated and regenerated, and then relatively cool air from the outlet of the adsorption tower is sent to the regeneration tower via the solenoid valve 10 and orifice 6, and the solenoid valve 3 is opened to release hot air to the outside of the adsorption tower. , the adsorption tower is activated by cooling. However, in the case of this compressed air dehumidifier, the amount released to the outside of the adsorption tower has a purge rate of about 10 to
There was an inconvenience that the near loss due to purge was around 15%.

ものである（特開昭５６−１３６６１９）。Next, what is shown in FIG. 6 includes dryers 21 and 22 filled with filler, a water-cooled cooler 23 connected via a four-way valve, and a dryer 21 and 22 connected to the four-way valve and the three-way valve. This is a system in which the dryers 21 and 22 are alternately used for dehumidification or regeneration (Japanese Patent Application Laid-Open No. 136619/1983).

が出来ないといった不都合があった。However, since the cooler of this type is water-cooled and does not use a refrigerator, it has been impossible to continuously obtain dry air with a low dew point of -70°C. Regarding the cooling activation of the dryer during regeneration, air cooled by an aftercooler installed in the compressed air discharge pipe is sent into the dryer, but since the air coming out of the aftercooler is not of a low dew point, Since moisture adheres to the adsorbent during the cooling process, it is inconvenient that it cannot be regenerated sufficiently.
（発明が解決しようとする問題点）

のニアロスが極めて大きいといった不都合があった。(Problems to be Solved by the Invention) As mentioned above, the conventional adsorption type compressed air dehumidifier has the disadvantage that the consumed heating energy is wasted, and the purge is required when regenerating the adsorption tower. There was an inconvenience that the near loss caused by this method was extremely large.

の水分がパージされる。(Function) In the apparatus according to the present invention, when the adsorption tower A is used for moisture absorption and the adsorption tower B is used for regeneration, one solenoid valve is closed and the other t-magnetic valve is opened. Then, high-temperature hot air is sent into the adsorption tower B from the air compressor 44. At this time, the moisture adhering to the adsorbent in the adsorption tower B is evaporated by the heat. Then, this hot air exchanges heat with the adsorbent to be slightly cooled and sent to the cooling/dehumidifying means. There, the air is cooled again, further dehumidified, and sent to adsorption tower A via the three-way valve. This sent dry air is further dehumidified by an adsorbent to a dew point of -70°C. The dehumidified air is supplied to the outside via a solenoid valve. After the moisture evaporation in the adsorption tower B to be regenerated is completed, the solenoid valve is switched so that the hot air is sent directly to the cooling/dehumidifying means, and the adsorption tower B to be regenerated can be activated. Dry cooling air is sent from the air outlet of adsorption tower A through an orifice to purge moisture in adsorption tower B.

８を閉から開に切り替える。In the embodiment according to the present invention with the configuration described above, when adsorption tower A is used for adsorption and adsorption tower B is used for regeneration, first close the solenoid valves 45.48.55.56°58.62. , the solenoid valves 46, 47, and 57 are opened. Then, air at a high temperature of about 250 to 300° C. flows from the air compressor 44 into the adsorption tower B via the electromagnetic valve 46, and evaporates the water attached to the adsorbent in the adsorption tower B. At this time, the high temperature air exchanges heat with the filler and is slightly cooled. This cooled air flows to the precooler 43a via the electromagnetic valve 57 and the check valve 57a. The water is dehumidified in the preliminary cooler 43a and the condensed water is discharged to the outside of the reservoir in the drain separator 43c. The air whose dew point has been lowered through the precooler 43a further goes to the cooler 42, where it is dehumidified to a dew point of about -17°C, and then enters the adsorption tower A via the three-way valve 41, where moisture is absorbed until the dew point is below -70°C. Ru. The dry air that has sufficiently absorbed moisture is passed through the solenoid valve 47. It is sent outside the machine via the check valve 49.
On the other hand, the adsorbent in the regeneration tower B, which has been heated and released moisture, must be cooled to approximately 50 to 60°C in order to activate its adsorption ability, but in this case, the solenoid valve 46.57
At the same time as switching from open to closed, the solenoid valves 55, 62.6
Switch 8 from closed to open.

The water flows to the cooler 42 via the check valve 61 and the precooler 60. The air dried in the adsorption tower A is then passed through the orifice 51° check valve 53. It flows into the adsorption tower B through the electromagnetic valve 55, and the thermal energy inside the adsorption tower B is released to the outside. This emission amount is the same as the air compressor 44
This amount is very small, about 3-4% of the total amount pumped into the device. In reality, the heating and cooling steps take half the time, so the amount released is only 1.5 to 2%.
