Description
Technical field
The utility model is related to the device for preparing dry ice, is specifically related to a kind of direct by liquid titanium dioxide using high-pressure pump
Carbon pressure contracting solidification prepares the device of dry ice.
Background technology
Carbon dioxide is in being colourless, tasteless gas under normal temperature, and molecular weight is 44, and density is at standard conditions
1.977g/L, proportion is about 1.5 times of air；Solubility in water is reduced with the rise of temperature, with the rise of pressure
And increase, temperature is 0 DEG C, when pressure is 0.1MPa, and solubility is 1.79Ncm3/ g, and it is identical in temperature, and pressure is 1.0MPa
When, its solubility is 15.92Ncm3Every volumes carbon dioxide of 100 volume water soluble 88 under/g, 20 DEG C of normal pressures, carbon dioxide is dissolved in
A water part is with water reaction generation carbonic acid；The critical point temperature of carbon dioxide is 31.06 DEG C, and critical pressure is 7.382MPa, is faced
Boundary's density is 468kg/m3；Fusing point（Triple point）For -56.57 DEG C, triple point pressure is 0.416MPa；Boiling point is -78.45
DEG C (distillation be dry ice)；Work as CO2In -56.57 DEG C when, it is that three phase point is that gaseous state, liquid, solid-state coexist；When temperature is in
At 31.06 DEG C~-56.57 DEG C, CO2Coexisted for gaseous state, liquid；When temperature is in -56.57 DEG C~-78.45 DEG C, CO2For gas
State, solid-state coexist.In atmospheric conditions, carbon dioxide can not exist in fluid form.At 20 DEG C, by carbon dioxide pressurization
It is to become colourless liquid to 5.73Mpa, is typically liquefied as colourless liquid, liquid two in 7.092MPa under normal temperature (70 atmospheric pressure)
Aoxidize carbon density 1.101g/cm3, often it is compressed in steel cylinder and stores, solid is changed into -56.6 DEG C, 0.527Mpa.Liquid two
The influence that the density of carbonoxide is stressed is little, and be influenced by temperature it is then larger, such as 31.0 DEG C when, density is 463.9kg/
m3, density is 1074.2kg/m at -30 DEG C.Volume is only about the 1/356 of atmospheric carbon dioxide after co 2 liquefaction, is solidified into
Volume is only gaseous about 1/764 after shape.Drikold can be congealed into when liquid CO 2 evaporates or when pressurizeing cooling,
" dry ice " is commonly called as, is a kind of cryogenic coolant, density is 1.56g/cm3.When liquid carbon dioxide decompression is evaporated rapidly, a part
Gasification heat absorption, another part quenching becomes to avenge shape solid, will avenge shape solid compressed, as ice-like solid " dry ice ", dry ice exists
0.1-0.13MPa, -78.5 DEG C when can directly distil and become gas.
With the raising of social environment protective awareness, the application of the popularization such as CCS technologies of industrial carbon emission reduction technology, trapping
Carbon dioxide conversion is liquid carbon dioxide, and the storage-stable of substantial amounts of liquid carbon dioxide or application are by as a new skill
Art problem, and it is then an effective outlet that liquid carbon dioxide is solidified into dry ice processed, dry ice is the carbon dioxide of curing molding,
Volume contraction is to the 1/356 of atmospheric carbon dioxide after co 2 liquefaction, and volume contraction is to gaseous 1/764 after curing molding.
Dry ice can directly distil as the gas of hundreds times of volume because of its heat absorption, and noresidue, it is nontoxic, tasteless, non-ignitable and can sterile character,
Using increasingly extensive, the industries such as food and drink, food, chemical industry, medicine, health, industry, video display, meteorology and its cleaning skill can be applied to
In art.
Currently, CO2Prepared by liquefaction and dry ice can be divided into high-pressure process（8MPa）And middle-pressure process（1.6MPa~2.5MPa）, low pressure
Method（0.7MPa~0.9MPa）.High-pressure process can realize gas CO2Liquefy at normal temperatures, compressor is generally three stage compression or level Four
Compression, energy consumption is very big, and liquefy CO2Cool again through throttling expansion, operative liquid CO2Enter dry-ice machine after being converted into snow shape solid-state
Shaping prepares dry ice；Mesolow method can realize gas CO2In cryogenic conditions（Such as cryogenics）Lower liquefaction, then enter through throttling expansion
One step cools, operative liquid CO2After being converted into snow shape solid-state dry ice, compressor power consumption relatively high pressure are prepared into dry-ice machine shaping
Method is much lower.
Existing dry-ice machine is usually to utilize high pressure or mesolow liquid CO2Throttling expansion cooling, make partially liq CO2It is solidifying
Form solid snow shape CO2, then, press into closely knit bulk or pelletized product through plunger in dry ice forming machine.Generally, can be with
By liquid CO2In middle pressure（1.6MPa~2.5MPa）Or low pressure（0.7MPa~0.9MPa）Dry ice is introduced by auto feed valve down
The a little higher than triple point pressure of pressure in the snow bucket of press, bucket（About 0.55MPa）；Feeding quantity is by Timer Controlling or according to snow bucket
Interior liquid level is adjusted.Throttling expansion decompression makes operative liquid CO2Vaporization, the cold steam of generation makes liquid by heat exchange
CO2Further cooling.When being cooled to triple point（-56.6℃）Hereinafter, when pressure drops to 0.518MPa, liquid CO2It is solidified into
Avenge shape dry ice.Finally with snow shape CO of the press generation2It is pressed into dry ice lumps or particle.The liquid that traditional dry-ice machine passes through elevated pressures
Dry ice is made after the solidification of body segment stream vaporizing section, i.e., by after liquid carbon dioxide throttling vaporization separation atmospheric carbon dioxide, compresses
The part snow shape carbon dioxide of heat release solidification can just obtain dry ice, wherein the amount of the carbon dioxide lost is about the dry of acquisition
Two times of ice amount, dry ice yield is only 0.3~0.4.Existing dry ice structural establishment processed is complicated, and volume is big, invests larger, is produced into
This is also higher.
On the other hand, with the development of hydraulic technique, 100MPa~500MPa low energy consumption high-pressure pump is very ripe extensive
The report of any research or practice, and CO are had no applied to fields such as hydraulic pumping, Water Cuttings, but in dry ice preparation field2's
Physical property and three-phase diagram feature show CO2Compressible Phase Transformation Characteristic.How CO is utilized2Physical property and three-phase diagram
The compressible Phase Transformation Characteristic of display, developing a kind of high more easy dry ice preparation facilities of smaller, dry ice yield of investing has in fact
The value on border.
