Glove type operation box

Abstract

Provided is a glove type operation box which can reduce the concentration of carbon dioxide. A dehumidification rotary device is divided into an absorption area (2), a purification area (3), and a regeneration area (4) relative to the rotation direction of the dehumidification rotary device, a regeneration circulating path allowing air to circulate by passing through the regeneration area (4) is arranged to enable outside air to mix with a part of the regeneration circulating air for cooling. On this basis, the air passes through a carbon dioxide absorption tank (10) filled with a carbon dioxide absorbent composed of alkali metal hydroxide or alkali earth metal hydroxide, and then passes through the absorption area (2), and the air in the absorption area (2) is supplied to a drying chamber (16); moreover, the air enters into a cooling device (22) via the backflow air valve (18), so that the cooled and dried air can be returned back to the absorption area (2).

Description

technical field

[0001] The present invention relates to a glove box. The so-called glove box means that the inside of the glove box can be kept in a state of extremely low humidity, and the hand can be inserted from the outside of the box through a sealed glove. Equipment for experiments, etc. in a dry environment. It is widely used in factories, laboratories, analysis rooms, etc., and is an indispensable equipment for experiments that need to be carried out in a dry environment. The invention provides a glove-type operation box which can not only precisely control the air dew point (Dew point) in the box, but also greatly reduce the carbon dioxide concentration in the supply air. Background technique

[0002] When dehumidifying the air in a specific box, the method of using a refrigerator to cool the air, dew condensation and dehumidification has little energy consumption, but it is very difficult to reduce the humidity of the air to the dew point temperature below zero. ...
