Problems solved by technology

However, because the traditional 5A molecular sieve adsorbs carbon dioxide and absorbs water strongly at the same time, there is competitive adsorption, so the pre-drying treatment has to be used, which will make the device design more complicated, control difficult, weight, volume, and regeneration power consumption are large, and , the traditional zeolite molecular sieves are granular molecular sieves, and these molecular sieves are

Example Embodiment

[0038] Example

[0039] The carbon dioxide and moisture (humidity) control scheme in a 6-person cabin. The design goal is to remove carbon dioxide and moisture with an efficiency of not less than 70%, the adsorbent has the ability to regenerate, and the regeneration energy consumption is not more than 300W, of which:

[0040] Carbon dioxide control ability: meet the requirements of 6 people in a confined space (CO2 output of 6kg / d) to use, control the CO2 concentration in the confined space below 0.8%;

[0041] Humidity control ability: It can be used in a group of 6 people (humidity production 12kg / d) in a confined space, and the relative humidity in the confined space is controlled between 30% and 70%.

[0042] As attached figure 1 , The system equipment design is as follows:

[0043]

[0044] Use the above equipment and attached figure 1 Indicated technical process, the control of carbon dioxide and moisture (humidity) in the cabin meets the requirements of use and achieves the ex

Abstract

The invention belongs to the technical field of space flight and aviation life support and environmental control, particularly relates to an integrated combined treatment device and method for non-consumption type carbon dioxide and water. The device comprises an air supply unit, an adsorption and desorption unit, and necessary control valves, connection pipelines and control systems, wherein the adsorption and desorption unit is an integrated separator and is divided into a lower adsorber and an upper adsorber; a hydrophobic carbon dioxide hollow fiber molecular sieve in the lower adsorber is used as an adsorbent and is used for adsorbing the carbon dioxide in gas; a mesoporous zeolite hollow fiber molecular sieve in the upper adsorber is used as an adsorbent and is used for adsorbing the water in the gas; a desorption device is arranged between the lower adsorber and the upper adsorber and is used for performing heating and regeneration on the used adsorbent. A plurality of integrated separators can be provided, which are connected in parallel or series to operate. The device can effectively realize integrated treatment of the carbon dioxide and the water in a cabin, and can reduce the weight and the power consumption of a system and the consumable supply demand.
