Description
Technical field
It the utility model is related to supercooling ability of swimming characteristics of dynamic ice slurry preparation technique, and in particular to a kind of mistake for reducing pre- heat loss
Cold water formula characteristics of dynamic ice slurry preparation system.
Background technology
Supercooling ability of swimming characteristics of dynamic ice slurry preparation technique is a kind of new and effective ice making technique, and its general principle is using efficient
Plate type heat exchanger is liquid clear water cooling down to -2 DEG C.The natural supercooling characteristic being had according to water, when it leaves heat exchanger
Although temperature remains to keep non-icing liquid condition under certain condition, this state already below freezing point temperature (0 DEG C)
Under water be subcooled water.Subcooled water enters the brilliant device of rush immediately after leaving heat exchanger, and it is the appearance for existing Ultrasonic Radiation to promote brilliant device
Device, subcooled water will be changed into ice slurry rapidly under the stimulation of ultrasonic wave wherein, be subsequently conveyed to store in Ice Storage Tank.Due to

Ice-making technology.It is fresh-keeping etc. that supercooling ability of swimming characteristics of dynamic ice slurry preparation technique is widely used in central air-conditioning cold-storage, technical cooling, fishery
Field, there are very wide market prospects.
A key issue for needing to solve in supercooling ability of swimming characteristics of dynamic ice slurry reparation technology is to prevent ice crystal from entering subcooled water
Heat exchanger.Most of water in supercooling water- to-water heat exchanger is in the supercooled state less than 0 DEG C, is that one kind is below the freezing point but temporarily gone back
The metastable state liquid not frozen, it has very strong phase transformation icing trend under the stimulation of various external interferences.Because ice crystal was
The excellent nucleator of cold water, therefore it is a problem the most prominent in these disturbing factors that ice crystal, which induces,.Water- to-water heat exchanger is subcooled
In once be mixed into ice crystal, then easily induce heat exchanger and ice blockage occur.In water- to-water heat exchanger is subcooled, liquid subcooled water does not allow
Freeze, because once freezing will cause heat exchanger flow circuit to block, lose exchange capability of heat, whole ice making operation is forced to interrupt.Serve as
After cold water leaves heat exchanger, enter and promote that subcooled water just is changed into ice slurry in brilliant device.Although aqueous water changes into subcooled water
Physical filtering is had been carried out before hot device, even if being also difficult to thoroughly eliminate micron order ice therein with as little as 5 μ filter core
Crystalline substance, and the ice crystal of these particle diameters is still enough to induce supercooled water icing.Therefore, it is subcooled in ability of swimming ice slurry preparation technique and eliminates liquid
The problem of micron order ice crystal in water is very crucial.
The method for eliminating micron order ice crystal in the aqueous water for entering supercooling water- to-water heat exchanger commonplace at present is preheating method.

The water of device is preheating to 0.5 DEG C from 0 DEG C, and the supercooling coolant-temperature gage for leaving supercooling water- to-water heat exchanger is -2 DEG C, that is, water- to-water heat exchanger is subcooled
The cooling refrigeration duty undertaken is the sensible heat amount of 0.5- (- 2)=2.5 DEG C, and wherein 0.5-0=0.5 DEG C of sensible heat load is lost to ring
In border, the sensible heat load of 0- (- 2)=2 DEG C is then converted to the latent heat load required for preparing ice slurry.Therefore deduce that above-mentioned
Under technological parameter, the loss of refrigeration capacity caused by preheating is 0.5/2.5=20%, i.e., refrigeration system exports total cold in ice-making process
There is 20% to be lost in environment in amount have lost, only 80% is converted to the latent heat of phase change cold required for ice making.As can be seen here,
Loss of refrigeration capacity caused by traditional preheating method is too big, and this causes other power savings advantages that ability of swimming characteristics of dynamic ice slurry preparation technique is subcooled

After flowing through preventing transmission device 14, into the brilliant device 15 of rush.If water is less than 0 DEG C of subcooled water, promoting ultrasonic wave (figure in brilliant device 15
Not shown in) radiation under quickly generate ice slurry, the ice slurry of generation flows back to through the ice slurry pipe 401 of first switch valve 701 and first
The top of one point of groove 101.Because ice and water have density contrast, ice floats over above naturally, and water sinks to following naturally.Repeat above-mentioned follow
Ring, then the ice in first point of groove 101 is more and more, and water is fewer and fewer, the ice amount until storing full sets target.Generally,
Ice content (mass ratio) in Ice Storage Tank reaches 40% and terminates the ice making for dividing groove.
It is that water is carried out at cooling first if the device is to be stored at one, let cool ice making is carried out after service life terminates
Reason.Because the water temperature that a cycle terminates in rear Ice Storage Tank has been raised to a higher temperature, such as 11 DEG C.Therefore, exist
At the initial stage of above-mentioned operating mode operation, it is that sensible heat cooling is carried out to the water in first point of groove 101 first, is still produced in system without ice slurry
It is raw.When water temperature therein is from after being down to 0 DEG C for 11 DEG C, the water at low temperature come out from supercooling water- to-water heat exchanger 13 enters the mistake less than 0 DEG C
Cold state, at the same time promote to start to generate ice slurry in brilliant device 15, also begin to ice slurry be present in first point of groove 101.Thus cause
Start the solid-state crystal ice granule sucked with current occur in first time intake pipe 201, the larger portion of volume in these crystal ice granules
Dividing will be filtered out by first filter 801, but micron-sized tiny ice crystal particle still has and can be admitted to subcooled water heat exchange
In device 13, if not preventing measure, the hot side subcooled water being subcooled in water- to-water heat exchanger 13 will be induced generation icing by tiny ice crystal
Block.
After starting to generate ice slurry in first point of groove 101 as described above, start regulating valve 602 and first in regulation second and lower
Valve 501 is saved, in the case where the original state of other valves keeps constant, to be taken from the top second of second point of groove 102
Water pipe 302 take out part high-temperature water, with taken out through first time intake pipe 201 from first point of bottom of groove 101 0 DEG C of water at low temperature (by
In having begun to generate ice slurry in first point of groove 101, therefore its water temperature has reached 0 DEG C) mixed, temperature is slightly after mixing
Raise and be sent into supercooling water- to-water heat exchanger 13 through water pump 11.Target temperature after above-mentioned mixing is 0.5 DEG C, and the purpose is to above-mentioned warp
The micron order ice crystal in water after the filtering of first filter 801 melts, to ensure that the hot side for entering supercooling water- to-water heat exchanger 13 enters
Mouth enters without ice crystal completely.Above-mentioned mix temperature is exported with the cold side input port tie point of preheater 16 to upper by being arranged on water pump 11
The temperature sensor 12 stated on the pipeline section between the supercooling hot side entrance of water- to-water heat exchanger 13 monitors.Monitored when temperature sensor 12
When water temperature is less than 0.5 DEG C, the aperture of regulating valve 602 increase on second, first time the aperture of regulating valve 501 reduces；Work as temperature sensor
When 12 water temperatures monitored are higher than 0.5 DEG C, the aperture of regulating valve 602 reduces on second, the first time aperture of regulating valve 501 increase.Always
It, by forward and reverse regulation to regulating valve 602 and first time aperture of regulating valve 501 on second, realizes supercooling water- to-water heat exchanger 13
The constant control that 0.5 DEG C of hot side inlet water temperature.
In above-mentioned running status, through the first ice slurry pipe 401 return to first point of groove 101 frozen water total amount (quality) just etc.
The water summation that intake pipe 302 takes out on through first time intake pipe 201 and second.Due to the bottom of dividing plate 9 between each point of groove
There is water level balance hole 10, therefore the liquid level water level of each point of groove is not in difference.So mean that through intake pipe on second
302 waters taken out from second point of top of groove 102 will equally between first point of groove 101 and second point of groove 102 water level
Balance pipe 10 flows back to the bottom of second point of groove 102, and simply top outflow is high-temperature water, and what bottom was flowed back to is 0 DEG C of water at low temperature.By
Different in high and low temperature water density, high-temperature water will occupy top all the time, and water at low temperature occupy bottom all the time.With entering for ice-making process
OK, the interface in second point of groove 102 between high-low-temperature will be moved progressively from the bottom up.Such high and low temperature moisture stratiform
Condition ensure that intake pipe 302 can get high-temperature water all the time on second.
During above-mentioned ice making operation, pre- heat regulating valve 17 is closed, and preheater 16 is not involved in running, therefore does not have cold
It is lost to by preheater 16 outside system.
The subcooled water target temperature that the hot side outlet of water- to-water heat exchanger 13 is subcooled is -2 DEG C, according to conservation of energy principle, when -2 DEG C
Subcooled water be completely transformed into 0 DEG C of ice slurry under adiabatic conditions after, the mass content of solid ice therein is 2.5%, i.e., first
The water that about 2.5% is had after the every overall circulation primary of water divided in groove becomes ice.Reach the final state for storing full ice, i.e., 40%
During the state of ice content (IPF=40%), then overall circulate about 16 times is needed.If with t DEG C in second point of groove 102 of high-temperature water
Water at low temperature with 0 DEG C in first point of groove 101 is blended into 0.5 DEG C, and the mixing ratio of high and low warm water can be obtained according to conservation of energy principle
(mass ratio) is 1/ (2t-1).With the water capacity (each point of groove is identical) in single point of groove for reference units 1, according to above-mentioned each point
Groove ice content IPF=40% is the target for making full ice, and first point of groove 101 is from starting to generate ice slurry to the full ice (IPF=40%) of storage
Overall process in need second point of groove 102 to provide the high-temperature water water for being used for melting micron order ice crystal be 8/t.When t=11 DEG C
When, above-mentioned required high temperature water is 0.73；When t=8 DEG C, required high-temperature water water is 1.Above-mentioned result of calculation shows, when upper
When Ice Storage Tank temperature is 11 DEG C at the end of one wheel is let cool, another required for making the ice of a full point of groove divides the high temperature water of groove
Only need therein 73%；And 1 point of groove is then needed just when Ice Storage Tank temperature is minimum as little as 8 DEG C at the end of last round of let cool
100% water.Above-mentioned analysis shows, if it is last round of let cool terminate after water temperature in Ice Storage Tank be not less than 8 DEG C, then this practicality
The new used high-temperature-hot-water by the use of a point of groove divides the thermal source of the thawing tiny ice crystal needed for groove ice making to be as another
Fully sufficient, therefore it is in actual applications and completely achievable.
After first point of groove 101 reaches state (IPF=40%) of the full ice of system, system is then started to the by valve transfer
Two points of grooves 102 carry out ice making.As described above, the water in second point of groove 102 is because participating in preheating operation during first point of 101 ice making of groove
Partly or entirely it is down to 0 DEG C afterwards, therefore the ice making to second point of groove 102 will be only of short duration or do not have sensible heat temperature-fall period,
It will start to generate ice slurry quickly or immediately.As the above-mentioned process to first point of ice making of groove 101, now with the 3rd point of groove
103 high-temperature water is as the thermal source to melting tiny ice crystal in second point of ice-making process of groove 102, its principle and the complete phase of process
Together, repeat no more.Valve controlling state now is：Second time regulating valve 502, which is in, opens and keeps the adjustable shape of aperture
State, second switch valve 702 are opened, and regulating valve 603 keeps the state of adjustable aperture on the 3rd, in addition remaining all valve
All closed including lower regulating valve 503 and 501, upper regulating valve 602 and 601, switch valve 703 and 701, and the grade of pre- heat regulating valve 17
Close.
When only remain last and divide 103 non-ice making of groove and remaining divide groove all to make full ice when, system is by valve transfer to right
Last divides groove 103 to carry out ice making.Valve controlling state now is：The three times regulating valves 503 are in opening, and the 3rd
Switch valve 703 is opened, and pre- heat regulating valve 17, which is in, to be opened and keep the adjustable state of aperture, in addition remaining all valve
Including Close Alls such as lower regulating valve 501 and 502, upper regulating valve 601,602 and 603, switch valves 701 and 702.Due to now
Through not having the non-ice making of high-temperature water to divide groove, therefore last is divided and can not be used and foregoing each point again during 103 ice making of groove
Identical pre-heating mean during groove ice making, and can only be by the way of being preheated with traditional external heat source.It is of the present utility model
Preheating method is that 0 DEG C of water that water- to-water heat exchanger 13 is subcooled to being sent into by the preheater 16 being connected in parallel on the import and export pipe of water pump 11 enters
Row heating.The hot side thermal source of preheater 16 comes from external heat source circulatory mediator 19, the most frequently used refrigeration host computer can be used to cool down
Water circulation etc..The cold side circulation of preheater 16 is then the part distributed using the import and export pressure difference of water pump 11 from supervisor
Low temperature water circulation, the preheated regulating valve 17 of water at low temperature being diverted enters the cold side input port of preheater 16, hot wherein
