Specific embodiment
Explanation that the present invention will be further explained with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of energy-saving low deuterium-oxide distillation system, the distillation system include rectifying column 1, steam generator 2,
Tower bottom heating mantle 3, first heat exchanger 4, second heat exchanger 5, gas-liquid separator 6, Pistonless compressor 7, water pump 8 and vacuum pump
9,1 top of rectifying column is connected with 4 one end of first heat exchanger, the first heat exchanger 4, Pistonless compressor 7 and second
Heat exchanger 5 is sequentially connected to form a heat exchange circulation access, and described 5 one end of second heat exchanger is connected with steam generator 2
It connects, the steam generator 2 is connected with rectifying column 1, and 1 bottom of rectifying column is connected with tower bottom heating mantle 3, first heat
4 other end of exchanger is also connected with gas-liquid separator 6, and described 6 one end of gas-liquid separator is connected with water pump 8, described water pump one end
It is connected to 1 top of rectifying column, 6 side of gas-liquid separator is also connected with vacuum pump 9.
1 shell of rectifying column uses cross-linked polyolefin tubing or stainless steel pipe.The Pistonless compressor 7 is Roots's pressure
Contracting machine.
Specific implementation process are as follows: in distillation system operational process of the invention, vacuum pump 9 provides very for the distillation system
Altitude is filled with structured packing inside rectifying column 1, provides swapace for water is gentle, steam generator 2 provides 60~90 °C
Vapor, and rectifying column 1 is injected steam into, vapor is spread inside rectifying column 1 rises to tower top, from 1 tower top of rectifying column
Vapor out makes vapor become liquid after the condensation of first heat exchanger 4, wherein a part of liquid is from gas-liquid separation
Device 6 is discharged, and becomes desired low deuterium-oxide；
Another part liquid then in injection rectifying column 1, is led at the top of rectifying column after the separation of gas-liquid separator 6 by water pump 8
The power for crossing control water pump 8 and Pistonless compressor 7, can control the liquid fraction back to rectifying column 1, obtains required concentration
Low deuterium-oxide, this partially liq flows downward in rectifying column 1, swaps with the vapor of rising, at this time in gas phase and liquid
Xiang Zhong, hydrogen isotope protium and deuterium will be enriched in gas phase and liquid phase, protium is rich in the gas phase respectively due to the difference of distribution coefficient
Collection, deuterium is enriched in the liquid phase, when vapor is full of rectifying column 1, integrally runs up, during running up, the concentration of protium is got over
Come higher, when arriving 1 top of rectifying column, the protium concentration of vapor reaches highest, and leaves rectifying column 1 in a gaseous form, and liquid portion
Point flow downwardly into 1 bottom of rectifying column, under the thermodynamic activity of tower bottom heating mantle 3, a part of water boils again, become vapor to
Rectifying column 1 is then discharged in upper diffusion, another part.
First heat exchanger 4 is used to the cooling vapor come out at the top of rectifying column 1, and second heat exchanger 5 is used to heat
The water of steam generator 2 is flowed into, it is gentle that gas-liquid separator 6 is used to separate water after cooling, and water pump 8 is used for part liquid from essence
It evaporates top of tower to be injected into rectifying column 1, tower bottom heating mantle 3 is used to maintain the boiling of bottom liquid, while also discharging part
Liquid.
Pistonless compressor 7 and first heat exchanger 4 and second heat exchanger 5 form heat exchange circulation access, the heat exchange
Filled with flow media (such as: water) in circulation path, when Pistonless compressor 7 is run, in flow media will be constantly by liquid
It is changed into gaseous state, and is transformed into liquid from gaseous state, shows as 4 refrigeration of first heat exchanger that will be connect with tower top, and and steam
The vapor come out at the top of rectifying column 1 can be condensed into water, while again will by 5 pyrogenicity of second heat exchanger that generator 2 connects
The heat energy transfer released after vapor condensation is to steam generator 2, thus realize recycling for energy, such steam generator
2 just only need seldom additional thermal energy to maintain the boiling of water, to reduce the energy of whole system consumption, can reduce 80%
Energy consumption, to reach energy-efficient purpose, this just produces low deuterium-oxide for low cost and provides ideal solution.
