Glove box

Abstract

The present invention aims to provide a glove box which enables the exposure point in the box to be controlled at any exposure point at a high precision and with less energy, and enables a device not to be complicated. The glove box is characterized in that a dehumidify rotating wheel is segmented into an absorption area (2), a purifying area (3) and a regeneration area (4) relative to the rotation direction of the dehumidify rotating wheel, so that a part of or all of an external gas passes the absorption area (2); the rest part of the external gas passes a circuitous channel which enables an upstream side branch point (28) and a downstream side confluence of the absorption area (2)to be communicated and possesses a flow control device, and is supplied to the box (5) as a supply destination. The temperature control of the exposure point in the box (5) is carried out by combining the regeneration temperature proportion control and the above circuitous flow control, and the temperature of the exposure point in the box (5) can be controlled at any exposure point temperature with less energy consumption and at a high precision.

Description

technical field [0001] A glove box refers to a box in which the humidity inside the box is kept at an extremely low level, and hands are inserted from the outside of the box through a sealed rubber glove (glove), thereby utilizing the dry environment in the box. experiment. The present invention relates to a glove box capable of controlling the dew point with high precision and reducing energy consumption. Background technique [0002] In the case of dehumidifying the air in a specific box, it is difficult to reduce the humidity of the air in the box to a negative dew point, although the energy consumption is small when using a refrigerator to dehumidify in the form of condensation. [0003] That is, in recent years, lithium-ion batteries, lithium-ion capacitors, and the like have been rapidly developed or improved. Lithium readily absorbs moisture from the air, deteriorating the performance of batteries or capacitors, so experiments accompanying these developments must be...

Problems solved by technology

[0015] Although the invention disclosed in the above-mentioned Patent Document 1 uses a desiccant to dehumidify the gas in the gas space and does not discharge the gas out of the system to reduce operating costs, the structure of the device is complicated and the device itself is huge, which causes the problem of increased initial cost.

[0016] In the invention disclosed in the above-mentioned Patent Document 2, the capacity of the glove box is smaller than that of a drying room (generally called DRYROOM (registered trademark)) that sends dry air to a closed room, so it may not be possible to control to an arbitrary dew point with high precision. question

[0017] On the other hand, in the invention disclosed in the above-mentioned Patent Document 3, when the closed chamber is adjusted to a low dew point, there will be a problem that it takes too much time to reach the predetermined dew point temperature, and the temperature of the heater for controlling the humidity will fluctuate greatly. The problem of not being able to control humidity with high precision

( image 3 etc.) When the capacity of the glove box is further increased, the amount of the adsorbent increases, and the container for putting the adsorbent also increases, resulting in a problem of increasing the size of the device
