Description

A microgravity laundry device based on the principle of atomized ozone

Technical Field

The utility model relates to the technical field of on-orbit life support for astronauts, and in particular to a microgravity laundry device based on the principle of atomized ozone.

Background technique

As manned spaceflight projects enter the space station era, astronauts' on-orbit stay periods are becoming longer and longer, and their work tasks are becoming increasingly arduous. The problem of cleaning their clothes while in orbit is becoming increasingly prominent. At present, there is no mature on-orbit laundry device suitable for microgravity environments at home and abroad; the clothes worn by astronauts are mainly in the form of consumables and cannot be cleaned on orbit.

Ground-based laundry equipment such as household washing machines usually use liquid media such as water and perchloroethylene for washing clothes. The clothes are fully mixed with the liquid medium through stirring, rotating and other forms of movement, and the clothes are sterilized and disinfected through chemical detergents dissolved in the medium. However, this laundry principle based on liquid media and chemical detergents cannot be applied to the microgravity environment on orbit, and the discharge of washing wastewater is also difficult to be directly treated by the existing space station regenerative water treatment system. The main reasons are as follows:

First, in a microgravity environment, liquid media will accumulate into clumps under the action of surface tension, making it difficult to fully mix with clothes; second, existing detergents produce a large amount of foam during the laundry process, and the foam in the laundry wastewater in a microgravity environment will block the circulation pump of the water treatment system; finally, the chemical detergents in the laundry wastewater are usually difficult to decompose, which exceeds the purification capacity of the existing water treatment system.
