Description

Humidifying device used during spacecraft packaging storage and transportation

Technical Field

The invention belongs to the field of humidifying devices, and particularly relates to a humidifying device used during packaging, storage and transportation of a spacecraft.

Background

Because some equipment of the spacecraft is sensitive to humidity, the relative humidity of the environment needs to be controlled within the range of 30-60% in various links of final assembly, test, storage and transportation of the spacecraft and the like.

The final assembly and test of the spacecraft are carried out in an AIT hall, and the hall environment control system controls the environment humidity. After the spacecraft is assembled and tested, the spacecraft is transported to a launching field through a packaging container, and the environmental humidity of the spacecraft during storage and transportation needs to be controlled by a humidifying device matched with the packaging container.

Spacecraft packaging containers typically employ a sealed structure. During the storage and transportation of the spacecraft, the high-purity nitrogen is filled in the packaging container to ensure that the air pressure in the container is higher than the air pressure in the external environment, and the container is always maintained in a micro-positive pressure working state. Under the state that the packaging container is closed and slightly pressurized, on one hand, water molecules in the external environment cannot enter the packaging container; on the other hand, the original water molecules in the packaging container are discharged out of the box along with the nitrogen in the pressure adjusting process, and the high-purity nitrogen almost containing no moisture is supplemented into the box; in addition, the packaging container takes away moisture in the box in the form of condensed water discharge in the process of temperature adjustment by using an air conditioner. Therefore, during the storage and transportation of the spacecraft inside the packaging container, the humidity of the environment inside the container gradually decreases along with the increase of the storage and transportation time, and special humidification equipment is required to be equipped for increasing the humidity inside the packaging container.

In the process of storage and transportation of the spacecraft, the humidifying device is positioned in the sealed packaging container, and the working conditions of shaking, inclining and bumping exist in the transportation process of using automobiles, trains, airplanes and ships as transportation carriers, so that no liquid overflows when the humidifying device is used under the transportation working condition, and the phenomenon of water vapor condensation can not be generated at any position of the spacecraft in the working process of the humidifying device.
