Description
Technical field
The present invention relates to a kind of gas-liquid separation device, more particularly to a kind of gas-liquid point being applied in the case of space flight microgravity
From device.
Background technology
In the presence of ground environment gravitational field, in order that gravitional force (energy) is minimum, density (quality) it is small it is upper,
Big will be in stable state under.In the gas liquid mixture of ground environment, the small gas of density can spontaneous rising, and density is big
Liquid can spontaneous decline, and form clear and definite interface, realize gas-liquid separation naturally.Therefore the gas-liquid separation technology of Ground Application is all
It make use of this natural phenomena, i.e. gas vent is upper, and liquid outlet is under, and gas-liquid separation device is simpler.
One of maximum difference of ground environment and space environment is the power of gravitational field, and gravity field strength is in ground environment
G, and the gravitational field very little in space environment, almost nil, referred to as microgravity environment.Under space microgravity environment, bubble loses
Remove buoyancy and be in suspended state, gas-liquid will be no longer automatically separated, and it will be a great problem that gas-liquid, which is completely separated,.Either from liquid
Gas is separated, or water outlet is separated from gas, it is all simple unlike under ground gravity environment.Therefore, space gas-liquid point
It is essential from technology.Gas-liquid separation technology is all employ in multiple subsystems of manned spacecraft, controls the gas in liquid
Humidity in concentration or air, aerial temperature and humidity control in sealed compartment is set in appropriate scope, to be lived with suitable people, be space flight
What employee made efficiently provides safeguard, and ensures the atmospheric environment of instrumentation normal operation in cabin, is reaching manned spacecraft just
The purpose often run.
In the manned task of the overwhelming majority, the separation of gas-liquid binary states is a primary demand between different material.Such as
In Active thermal control loop, the bubble in working medium reaches finite concentration, and the equipment such as circulating pump, heat exchanger can be caused to damage,
Meanwhile bubble can also influence the work of sensor, cause loop meter reading misalignment.
Space environment does not have supremacy clause as gravitational field, to realize that gas-liquid separation must utilize other by way of creation bar
Part.Since using passive type gas-liquid separation technology from early stage manned spaceship, gas-liquid separation technology is had been widely used in manned space flight
On device, and have developed into the integrated application of multiple technologies.The technology of space gas-liquid separation at present can be divided mainly into two major classes.1) it is static

Deng realizing gas-liquid separation.2) Dynamic Separation technology：Moving component in gas-liquid separation equipment be present, convection body is produced using motion
Force field, such as centrifugal force, and realize gas-liquid separation.Further static gas-liquid isolation technics can be divided into following 3 kinds again：
Gas-liquid separation technology based on capillarity, mainly utilize capillary caused by the characteristic and surface tension of hydrophilic/hydrophobic material
Effect；Cyclone gas-liquid isolation technics, it is main that caused centrifugation work is flowed in designed vortex pipeline using gas-liquid mixed stream
With；Inertial gas-liquid isolation technics, the main inertia using gas and liquid are widely different, liquid not the malleable direction of motion and by
Hydrophilic film is collected.Dynamic gas-liquid isolation technics is mainly centrifugal gas-liquid isolation technics, using caused by motor driven fluid rotary
Centrifugal force field realizes the separation of gas-liquid.
But all there are respective advantage and disadvantage in static, Dynamic Separation technology.Static separation method has power consumption less, without motion
Part, the advantages that easy care；But the fractional dose in its unit interval is few, separating rate is slow, and water wetted material etc. easily pollutes, work
Selectional restriction of the disruptive pressure by parameter when making.Dynamic Separation method fractional dose is big, and separating rate is fast, and stain resistance is strong, to it
Control can be realized by circuit etc.；But centrifugal force field generation mainly using the rotation of the rotor by motor driven come
Realize, need to coordinate driving part so moving component in separator be present, during work, need to consume excess power, this for
For the spacecraft of space, it should try one's best and avoid, and it also requires realizing the dynamic between rotor and Membrane Separator Cylinder for CFB Boiler

Gas-liquid separator, the separator utilizes centrifugal force, gas, liquid interface is occurred, when liquid is in the periphery of passage
By the aperture being pre-designed, gas-liquid separation is realized, the separator with only centrifugal force, and not utilize the used of gas-liquid
Sex differernce sets baffle plate, important technology -- the capillary force also separated without utilization space, and the separator inferior separating effect,
Energy-consuming parts be present, be not particularly suited for microgravity environment.Patent document CN104667584A proposes one kind and is based on porous material
Microgravity under screw type gas-liquid separator, the separator forms helical pipe using the deflection plate that is pre-designed, utilizes centrifugation
Power makes fluid-mixing produce separation, recycles lyophily phase, hates the characteristic of liquid phase porous material, realizes gas-liquid separation, the separator
Although make use of centrifugal force and capillary force, fractional dose is also little, and the easy quilt of porous material (hydrophilic/hydrophobic membrane material)
Pollutant blocks, and when the microorganism in liquid grows into finite concentration, also has ponding to the micropore on material, will all make pressure
Drop increase, separating property is influenceed, and repaired costly；Liquid and porous hydrophilic material in additional mixing fluid can not be well
Contact, contact area is also little, also can impact effect, and the device does not have safe pressure relief device, when separator interior block it is tight
During weight, device internal pressure insists on continuous increase, it will produces larger harm to spacecraft.
