  The present invention relates to a dewatering device arranged in a glove box and dehumidifying the inside of the glove box, and a glove box equipped with the dewatering device.

  Conventionally, a glove box is known as an apparatus used when handling substances, articles, organisms, microorganisms and the like (hereinafter referred to as “objects”) that hinder the operation in an open environment or in the atmosphere. This glove box has a glove box with a glove capable of inserting both hands and both arms from the outside. The glove box is sealed with the object contained inside and sealed. Both arms are inserted, and the object in the box is handled with both hands through this glove.

  In this case, it is often required to remove the moisture in the atmospheric gas in the glove box and keep the glove box in a dry state from the viewpoint of safety and the purpose of preventing deterioration of the object. In addition, a glove box equipped with a dehydration tower is also widely used (for example, Patent Document 1: Japanese Utility Model Publication No. 6-41826). In some cases, it may be necessary to remove gas components such as oxygen, hydrogen, carbon monoxide, and hydrocarbons, and a catalyst tower is provided to decompose and remove these unnecessary gas components using a palladium catalyst or a platinum catalyst. This is also common.

  However, the glove box equipped with the above-mentioned dewatering tower and catalyst tower is expensive to install these dewatering tower, catalyst tower and gas circulation mechanism, and is much more difficult than a glove box without these facilities. Expensive. Furthermore, the moisture adsorbent and catalysts packed in the dehydration column and the catalyst column usually need to be regenerated or activated at regular intervals, and during the regeneration or activation process, the glove box May not be available.

  On the other hand, there are many applications that do not require such dehydration treatment and unnecessary gas removal, and glove boxes that do not have the above dehydration tower or catalyst tower are widely used for users who are mainly used for such applications. in use. However, even such users may require a dehydration environment or may require oxygen removal. However, due to the high cost of the equipment and the frequency of use, the dehydration tower and the catalyst tower are provided. The reality is that we don't buy a glove box.
