Abstract

A dry air generator capable of dehumidifying and regenerating an adsorbent simply by flowing compressed air at room temperature into a drying tower. When a power supply is input, a timer circuit is activated to activate an electromagnetic valve. The humid air (compressed air) 1 that has passed through the electromagnetic valve flows into the drying tower 3 filled with the adsorbent, and the moisture is removed to become dry air. The dry air passes through the flow rate adjusting valve 4 and is divided into two systems. One system passes through the output valve 5 and is taken out as dry air 6. The other one passes through the flow rate adjusting valve 7 and flows into the drying tower 8 to dry the adsorbent, passes through the electromagnetic valve 2 and is exhausted 10 from the silencer 9. This flow is automatically switched according to the set time of the timer circuit 11 and reversely flows, and the same operation is performed to continuously generate dry air 6. Further, the flow rate is adjusted by the flow rate adjusting valve 4 (or 7) during the period in which the series of operations is performed, and the dew point temperature of the dry air 6 to be obtained is arbitrarily set.

Description

  The present invention relates to a device that uses a moisture adsorbent and generates dry air at room temperature by its dehumidifying action, and also relates to a device that has a self-regenerating function in drying and regeneration of the adsorbent.

  The conventional adsorption type dehumidifier uses two drying towers filled with a hygroscopic agent, dehumidifies by passing wet air through one tower, and the other tower performs regeneration of the adsorbent, continuously while switching the tower alternately. Dehumidification was performed. Temperature and humidity fluctuations occurred during this switching.

  In order to reduce the adsorption efficiency when the temperature of the humid air rises to increase the efficiency of the adsorbent, it is necessary to cool the humid air with a cooling device and increase the cooling efficiency. Was.

The regeneration method for the regenerating tower is to dry the adsorbent by creating hot air using a heating device and sending it to the adsorbent packed tower or by heating the regenerating tower. The exhaust gas after passing through the regenerated tower was hot and humid, and CO ₂ was discharged by using a heating device.

  Since the adsorbent in the regeneration tower is dried by heating, the temperature rises, and the temperature of the dehumidified air cannot be denied.

  Since it has a cooling device and a heating device, power consumption is large, and there has been a demand for improvement in terms of environment.

  In order to solve the problems described in the above technical background, the present invention can be easily dehumidified simply by injecting compressed air from the outside, allowing any dew point temperature to be set by adjusting the flow rate, and self-regeneration of the adsorbent. The purpose is to provide dry air at room temperature with an adsorption-type dehumidifier that has a function and takes environmental measures into consideration.

  The adsorbing dehumidifier of the present invention considers environmental problems, removes the cooling device and heating device, simplifies the structure, and easily dehumidifies only by injecting compressed air from the outside. By adjusting the dew point temperature with the flow control valve, it was possible to obtain dry air at room temperature. In addition, it was decided to regenerate the drying by reversing part of the drying air that was being generated as the drying agent for the regeneration tower.

Since the adsorption type dehumidifier of the present invention is configured as described above, the structure is greatly simplified and the dehumidifier is inexpensive. Moreover, temperature and humidity fluctuations could be suppressed by removing a heating device for regenerating the drying tower and a cooling device for increasing the adsorbent efficiency. At the same time, since there was no heating, the generation of CO ₂ could be reduced and environmental measures could be considered.

It is a structural diagram of the adsorption type dehumidifier of the present invention. It is a circuit block diagram which shows Example 1 of the adsorption type dehumidifier of this invention.

  Compressed air is allowed to flow from the lower part of the drying cylinder 3 (or 8) filled with the moisture absorbent material 13 that adsorbs moisture, the moisture of the incoming air is removed by the moisture absorbent and allowed to pass through, and the flow rate adjustment valve 4 (or The flow rate is adjusted in step 7) to determine an arbitrary dew point, and normal temperature dry air 6 is generated from the output valve 5. At that time, a part of the generated dry air flows into the regeneration drying tower 8 (or 3) to dry the adsorbent of the regeneration tower. The present invention is an apparatus for generating dry air at room temperature having the above-described configuration.

  By inputting the power supply 14, the timer circuit 11 is activated and the electromagnetic valve 2 is activated. The humid air (compressed air) 1 that has passed through the electromagnetic valve flows into the drying tower 3 filled with the adsorbent, and the moisture is removed to become dry air. The dry air passes through the flow rate adjusting valve 4 and is divided into two systems. One system passes through the output valve 5 and is taken out as dry air 6. The other one passes through the flow rate adjusting valve 7 and flows into the drying tower 8 to dry the adsorbent, passes through the electromagnetic valve 2 and is exhausted 10 from the silencer 9. This flow is automatically switched according to the set time of the timer circuit 11 and reversely flows, and the same operation is performed to continuously generate dry air 6. Further, the flow rate is adjusted by the flow rate adjusting valve 4 (or 7) during the period in which the series of operations is performed, and the dew point temperature of the dry air 6 to be obtained is arbitrarily set.
