Detailed description of the invention
As in figure 2 it is shown, novel evacuated chiller, including vacuum chamber 1 and vacuum pump 4, described vacuum chamber 1 and vacuum pump
Supersonic speed separator it is provided with between 4；
Described supersonic speed separator includes that with vacuum be 1 the first straight length a being connected, and is connected with the first straight length a
Lavalle pipeline section b, the second straight length c being connected with Lavalle pipeline section b, the diffuser d being connected with the second straight length c；Described
Diffuser d connects vacuum pump 4；
Described Lavalle pipeline section b includes the section of reducing e and divergent segment f；The left end of the described section of reducing e connects the first straight tube
Section a, right-hand member is connected with the left end of divergent segment f, and the right-hand member of divergent segment f connects the left end of the second straight length c；
Described Lavalle pipeline section b and the second straight tube junction are provided with cyclone 5；

Theory analysis: supersonic speed separator applies the principle of the first law of thermodynamics, by increasing inlet air flow flow velocity,
Stream pressure is converted into kinetic energy and obtains cooling；The ultimate principle that supersonic speed separates is to utilize Laval nozzle, makes fluid certainly
Accelerating to supersonic speed under body pressure effect, at this moment the temperature and pressure of fluid can drastically decline, and is that the water-cooled in fluid is congealed into little
Drop, then delivers droplets under the effect that strong air flow rotates and separates, and recompress dry gas.
Supersonic speed separation pipe is generally divided into four parts: stable section, Lavalle pipeline section, rectification straight length, diffusion pipeline section, should
The refrigeration of design convection cell and the separation of steam of device Each part all have a certain impact；Especially Lavalle pipeline section
The design of middle converging transition and increaser to refrigeration separating effect important.
1, stable section
Stable section, the i.e. first straight length, its effect is the even flow field making fluid, reduces the air-flow energy entering converging transition
Amount loss.Its diameter is relevant with Laval nozzle section throat diameter, and length is generally 10 times of Laval nozzle section throat diameter
Left and right.
2, Laval nozzle section
Laval nozzle is a kind of to have the contraction of precise geometry, expansion pipe, by the contraction of converging transition and gradually
Expand the expansion of section, the flow velocity of fluid can be brought up to supersonic speed level, and cause sharp temperature drop, converging transition and divergent segment
Junction is Laval nozzle section throat, and wherein, converging transition is intended to air-flow to accelerate to velocity of sound, makes fluid complete to expand compressed
Journey, keeps the stability that air-flow is good simultaneously, disturbance does not occur；Divergent segment makes the pressure of fluid raise, temperature reduces, and is one
Individual process of refrigerastion, fluid further speeds up in this section, makes phase change.
3, the second straight length
Fix a cyclone in rectification straight length front end, make through fluid produce a bigger centrifugal force, carry out
Separate.Diffusion pipeline section makes the gas expansion that residue is not liquefied,
4, diffuser
Diffusion pipeline section makes the gas expansion that residue is not liquefied, and gas pressure, temperature raise, and gas flow rate returns to Asia
Velocity of sound level.Discharge through vacuum pump.Liquefaction steam is discharged from row's mouth.
During use, humid air import is connected with vacuum chamber, outlet is connected with vacuum pump.Start vacuum pump, vacuum pump
The gas that the rapid extracting vacuum of meeting is indoor, along with the reduction of ambient pressure, the boiling point of water is also reducing, its evaporation unit quality
The heat that water is consumed but is increasing.And vacuum cooled is just dependent on realizing hypobaric vacuum state artificially, make vacuum
Moisture in the food material of cooling bath evaporates rapidly under hypobaric state, and it is owing to absorbing certainly that hydrone migrates in a large number
Fever of the body amount, just makes the interior of food material greatly to reduce, say, that while hydrone migrates rapidly, to take away the most rapidly
Heat within food material, it is achieved thereby that the purpose that food material cools down rapidly.Subsequently with the stream of a large amount of steam
Body flows through supersonic speed and separates pipe, when stable section, fluid is become uniform, stable.The most uniform and stable fluid enters Lavalle
The converging transition of section, fluid obtains and accelerates to supersonic speed, and complete to determine entropy turgor pressure compression process, subsequently enters divergent segment, fluid pressure
Power raises, and it is a process of refrigerastion that temperature reduces, and fluid further speeds up in this section, makes phase change.It is then passed through rotation
Stream device, make through fluid produce a bigger centrifugal force, separate.Eventually passing diffusion pipeline section makes residue not by liquid
The gas expansion changed, the rising of gas pressure, temperature, gas flow rate returns to subsonic speed level.Discharge through vacuum pump.Liquefaction water steams
Gas is discharged from row's mouth.Whole procedure structure is simple, and low cost is practical.
Above-described embodiment is merely to illustrate technical scheme that this utility model is embodied as rather than is limited, affiliated
The those of ordinary skill of technical field it should be understood that on the premise of this utility model objective, do not change its performance or
Any equivalent that embodiment of the present utility model is carried out by purposes substitutes or obvious modification, and all should contain please at this utility model
Ask in the range of protection.
