Abstract
The invention discloses a method for recovering and treating urine of an astronaut. On a spacecraft, urine obtained after the astronaut relieves nature is deodorized and sterilized by ozone and a chemical device and is then centrifugated and deposited at high speed, the supernatant fluid of the urine enters into a low-temperature freezing and vacuum humidity-taking device, vapor vaporized after the urine is condensed is taken out and collected to form purified recovered water, and finally the purified recovered water can be used as water for life after being sterilized at high pressure and high temperature, thereby achieving the aim of recovering and reusing water from the urine. A centrifugated deposit and a dried crystal of which the humidity is taken out at low temperature and in vacuum are used as garbage to be separately treated.
Description
Technical field
The present invention relates on the spacecraft water recycling, a kind of method that recycles to cosmonaut's urine.
Background technology
On spacecraft, the delivery expense of cosmonaut's domestic water is extremely expensive.In order to reduce the delivery expense of water on the spacecraft, slip-stick artist's thunder Buddhist nun at U.S. NASA space flight center. " the urine circulator " of Ka Te invention, reclaim problem to solve spaceborne water.Along with the development of China's Aerospace Technology, on spacecraft, how to solve cosmonaut's urine recycling, recycle, with the recovery that reaches water and can reach cosmonaut's domestic water requirement.The invention provides a kind of water recovery processing method that is used for cosmonaut's urine on the spacecraft.
Summary of the invention
The invention provides a kind of method for recovering and treating urine of astronaut, cosmonaut's urine is carried out the method for water recycling.
On spacecraft, cosmonaut's urine etc. is carried out the water recycling, at first adopt ozone gas, interpolation chemical reagent that urine is carried out deodorizing and sterilization, centrifugal removal throw out, its supernatant liquor enters in cryogenic freezing, the vacuum dehumidifier apparatus, extract, collect the steam that evaporates after its condensation and become pure recycle-water, disinfect and reach the requirement of domestic water through high pressure-temperature again.
The method applied in the present invention is: the urine after cosmonaut's urine enters in the ozone treatment apparatus and the ozone gas thorough mixing immediately, and adds chemical reagent automatically and carry out chemical treatment, reaches deodorizing and disinfectant purpose.Liquid is through the high speed centrifugation post precipitation, its supernatant liquor promptly enters in cryogenic freezing, the vacuum dehumidifier apparatus, urine is through the cryogenic freezing shape that build-ups ice, utilization low-temperature vacuum drying ratio juris starts the wet pumping unit system, extracts the steam that evaporates after its condensation, become pure recycle-water after the collection, carry out high pressure-temperature again and disinfect, can be used as domestic water and use, reach the recovery of urine, the purpose that recycles.Throw out after centrifugal and the dried xln of cryogenic vacuum dehumidifier are as rubbish thing otherwise processed.
Its beneficial effect of the present invention is on spacecraft cosmonaut's urine to be carried out the water recycling, solves the problem of cosmonaut's domestic water in the solar-system operation.
Specific implementation method
The embodiment of the invention to the water recovery processing method of cosmonaut's urine on the spacecraft is: its main support equipment is the automatic adding set of ozonizer, gas-water mixer and chemical reagent, supercentrifuge, cryogenic freezing device, vacuum wet pumping unit system and high pressure-temperature sterilizing unit.Urine after urine in the container of cosmonaut in special use enters the chemical reagent generation chemical reaction that reaches and add with the ozone gas thorough mixing in the ozone treatment apparatus immediately, reaches deodorizing and disinfectant purpose.Urine and ozone gas thorough mixing and with chemical reagent generation chemical reaction process in, combine with organism and inorganics in the urine, remove stink and form binding substances; After urine after treatment entered supercentrifuge centrifugation, its supernatant liquor entered in cryogenic freezing, the vacuum dehumidifier apparatus again.Utilization low-temperature vacuum drying ratio juris starts refrigeration system earlier, and urine is restarted vacuum dehumidifier system through the cryogenic freezing shape that build-ups ice, and extracts the steam that evaporates after its condensation, becomes pure recycle-water after the collection.Carry out a high pressure-temperature at last again and disinfect, can be used as domestic water and use, reach the water recovery of urine, the purpose that recycles.
Throw out after centrifugal and the dried xln of cryogenic vacuum dehumidifier are as rubbish thing otherwise processed.
Claims (2)
1, method for recovering and treating urine of astronaut, the urine that it is characterized in that the cosmonaut, after earlier carrying out deodorizing, disinfect by ozone and chemical devices, urine is through centrifugation, its supernatant liquor enters in the dehumidifier apparatus, through extracting the steam of its evaporation, becomes pure recycle-water after the collection, disinfect through high pressure-temperature more at last, can be used as domestic water.
2, method for recovering and treating urine of astronaut according to claim 1 is characterized in that urine precipitates through high speed centrifugation, and its supernatant liquor enters cryogenic freezing, vacuum dehumidifier apparatus, extracts the steam that evaporates after its condensation, and collecting becomes recycle-water.
