Description
Technical field
The present invention relates to heat source tower equipment technical fields more particularly to a kind of for docking the anti-of open type or closed type heat source tower
Freeze liquid enrichment facility.
Background technique
Coal changes electricity, and the die is cast, and it is also a kind of inevitable trend that vapour, which changes electricity,.The trend can be examined in terms of two
Consider, considers that pure electric energy is no any pollution to air, and electric energy can also drive heat pump from environmental angle first
Push low-temperature heat source to transfer at high temperature, high energy efficiency ratio has " energy enlarge-effect ", this " energy enlarge-effect " is also symbol
Close law of conservation of energy.
Institute's consuming electric power is not to be used as heat conversion, but be used to that low-temperature air energy heat is pushed to turn at high temperature
It moves, and low temperature heat energy is made to obtain use value, this technology is quite mature, during heat pump techniques developing history,
Especially heat source tower technology causes various countries to pay much attention to, and has been initially entered into implementation phase, is also no lack of many comercial operation success cases
Example, what commercial operation needed to consider from economic interests angle, as long as bringing economic interests to client, then market motive force
It can further increase.
We can do the calculating of an objective reality thus, have a look using expense required for natural gas boiler heating,
Take another look at air energy thermal source tower expense.It is understood that every cube of natural gas can produce 8000~8500kcal/m3Heat, pass through combustion
Its calorific value of gas boiler heat exchange can be lossy, the available utilization of usually only 80% calorific value, because there are also 20% thermal energy
As 130 DEG C or so flue gases exhaust, and this partial heat energy utilizes extremely difficult, cost recovery valuableness, then can be used for adopting
Warm actual calorific value is 8500 × 0.8=6800kcal, and every cubic natural gas is 3 yuan;According to air energy thermal source tower technology institute
The 6800 kilocalorie calorific values generated need power consumption expense as follows, because of 1kw=860 kilocalorie, 6800 kilocalories=7.9kw calorific value;So
And air energy thermal source tower Energy Efficiency Ratio is usually 4 times or so, that is to say, that expending 1kw electric energy can produce 4kw calorific value, then corresponding
7.9kw calorific value needs to expend electricity as follows, that is to say, that power consumption=7.9 ÷ 4=1.98kw in the case of the identical heating calorific value of output,
So air energy thermal source tower expense=1.98 × 1=1.98 member (electric market price is by the 1 yuan of calculating of every degree), and 6800 kilocalorie heating calorific values
Natural gas expense is 3 yuan, and the energy consumption cost that comparing can save is 34%, this is that every degree electricity is calculated by 1 yuan, every cubic natural gas
By 3 yuan calculate as a result, and natural gas is non-renewable energy resources, its price can rise steadily, current natural gas
It is nervous it is stated that this reason, and with the development of science and technology electricity-generating method is more and more close towards clean energy resource, and generate electricity
Cost is also lower and lower, so electricity price rising will not be faster than natural gas, or even can also make a price reduction possibility.
So using heat source tower heating technology three big benefits can be brought for client:
1,34% energy cost can be saved each winter for user;
Equipment service efficiency can be given full play to, maximizes and realizes the shared of device resource;
2, equipment investment and equipment maintenance cost are reduced, without boiler plant investment is increased, is reduced occupied by boiler plant
Space and computer room investment.
3, when heat pump unit Energy Efficiency Ratio is 2.6 times, the expense of boiler operatiopn just maintains an equal level with heat pump unit, and environment temperature is high
Heat source tower heat pump unit eer is generally 3.5 times when zero degree, and efficient cascade type heat pump unit is at -30 DEG C of environment temperature
Its Energy Efficiency Ratio can reach 3 times, as heat pump techniques its Energy Efficiency Ratio that is gradually improved can further increase, have very strong energy conservation
Emission reduction meaning.
For existing air-cooled air energy heat pump, we do following comparative analysis:
It is air-cooled be refrigerant directly and air heat-exchange, water cooling is that refrigerant carries out heat with air indirectly by water and exchanges,
Instead indirect mode refrigeration unit but it is more taller than the refrigeration unit efficiency of direct heat exchange mode go out one times or more, this mainly have with
What lower three factors determined:
1, heat exchange difference is critically important, and smaller its heat exchange efficiency of explanation of heat exchange difference is high, says plate heat exchanger efficiency why
Higher than shell-and-tube heat exchanger, exactly because the end difference of plate heat exchanger can achieve 1 DEG C, and shell-and-tube heat exchanger at most can be with
The end difference of realization be 5 DEG C (generally may only be 7 DEG C of temperature end poor), can be had more by the exchange heat indirect type heat exchange of relay of several roads
It is poor to accumulate temperature end, directly has certain advantage with air heat-exchange, although air-cooled unit can directly be exchanged heat with air,
For condenser refrigerant inlet temperature generally at 70 DEG C~90 DEG C, leaving air temp has 36 DEG C or more (at 35 DEG C of environment temperature),
And refrigerant exit temperature is at 42 DEG C~50 DEG C, the characteristic of air-cooled condenser is determined by environment temperature, and environment temperature is higher,
So condensation temperature is also higher.The condensation temperature of general air-cooled condenser is 7 DEG C~12 DEG C higher than environment temperature, 7 DEG C~12 DEG C this
A value we be known as heat exchange difference.Condensation temperature is higher, and the refrigerating efficiency of refrigeration unit will be lower, so we will control
This heat exchange difference not Ying Tai great.But if it is desired that the end difference of heat exchange becomes smaller and is less susceptible to, the heat exchange area of air-cooled condenser
And the air quantity of circulation increase its many end difference become smaller will not it is obvious that and air-cooled condenser cost it is higher.One
As temperature extremes be not higher than 55 DEG C, be not less than 20 DEG C.Water chiller condenser temperature be generally greater than 2 DEG C of cooling water leaving water temperature~
4 DEG C, cooling water outlet temperature is usually 37 DEG C~40 DEG C when summer outdoor temperature is 35 DEG C, it is clear that this temperature for accumulating out
End difference also only has 1 DEG C~3 DEG C, this is obviously more much smaller than air-cooled unit, its certain efficiency also wants much higher, though hardly realize water cooling
So using indirect heat exchange mode, its accumulation temperature end difference is but poorer than air-cooled direct heat exchange mode temperature end unexpectedly also much smaller, this
It is that wherein reason is, because of the heat transfer coefficient of water manyfold bigger than air, this is unquestionable, therefore is advised in identical heat exchange
Required heat exchange area is with regard to much smaller in the case of mould, and air-cooled unit must technically take the mode of remedying, that is, cold
Condenser air side adds heat transmission fin to solve refrigerant and air heat-exchange ability imbalance problem, and water cooling is just without this
A problem exists, and water and air are exchanged heat with pure reflux type, and the droplet of spray is wanted with air contact area
It is much bigger in limited bulk to carry out contact area than tubular type fin air cooling heat exchanger and air, there are also the evaporation of water can make it is cold
But coolant-temperature gage is lower than environment dry-bulb temperature, therefore its temperature end difference is just more small than air-cooled unit, so air-cooled unit COP is general
Only 2.8 or so, and water chiller generally has 5.8 or so.Be also for winter operation of heat pump situation its principle it is much the same,
Only carrying out pipeline switching docks evaporator with outdoor heat source tower, and is that anti-icing fluid carries out between evaporator and heat source tower
Circulation, and freezing is that water recycles between condenser and heat source tower, heating is that the steam that anti-icing fluid obtains in air is latent
The sensible heat of heat and air simultaneously leads to that anti-icing fluid is diluted and freezing point of solution temperature is caused to move up, and carrying out concentration to dilute anti-icing fluid is this
The key of the technology of ranks.
2, air-cooled unit refrigerant distance travelled is more much longer than water chiller refrigerant distance travelled, conveys gaseous fluid
Must use compressor, conveying fluid liquid must use circulating pump, either compressor or circulating pump they all must overcome stream
Body pressure and the resistance of ducting are conveyed come what is done work and are conveyed fluid liquid under equal mass fluid situations using circulating pump than pressure
Energy spent by contracting machine conveying gaseous fluid wants much less, because it is equal quality liquid that equal mass fluid gaseous state, which takes up space,
In the case of tens times or more, the Fluid pressure that such compressor is faced is also than pumping the big manyfold of faced Fluid pressure
(in the identical situation of pressure), so watt level spent by the compressor to do work to overcome pressure is certain to consume than pump
The energy taken is much more.Another aspect fluid distance travelled long pipeline resistance is bigger, occupied space multi-pipeline surface area resistance
Also bigger, therefore steam exhaust would rather be become condensed water and latent heat is scattered in air and goes to slattern by thermal power generation, be also unwilling
It recycles steam exhaust latent heat increasing enthalpy in steam exhaust indentation boiler using compressor, but uses booster pump only condensation
Water squeezes into boiler to be recycled.Reason is the same, therefore multi-joint unit efficiency is low is just not difficult to explain, especially from multi-joint
The farther away air conditioning terminal effect of host is excessively poor also one should to be made that explanation, this is exactly the same reason.If using water as heat
Just there is no this problem if the carrier of amount and cooling capacity conveys cooling capacity and heat with pump, so water chiller compares Air cooler
Group advantage is that it can have therefrom realization scale refrigeration and heating, realize limited body with long-distance sand transport cooling capacity or heat
Long-pending interior and air heat-exchange scale.
3, third problem be exactly air-cooled unit be used as operation of heat pump when evaporator will appear frosting situation, start when just
Its Energy Efficiency Ratio can reach highest when there is frosting, this is because steam solidification can discharge a large amount of latent heat in air, and calorific potential
Metric density can it is more several ten times larger than air sensible energy density more than, although the 0.3% of Water Vapor Quality duty gas, its latent heat meeting
Account for 25% (humidity big in the case where can account for 35% or more) of entire air energy heat, this effect be it is very significant, with
Its heating capacity understands sharp-decay to a certain extent for frost thickness increase, this is because the frost layer capacity of heat transmission is very poor, there are also white handles
Air duct is blocked, and intake reduces natural heat-exchange amount and can also greatly reduce.Air-cooled unit uses inverted running just to change thus
Frost, this appears to be utilized the steam latent heat in air, and actually this is not so, because the heat of its defrost is from room, not only
The experience of user is influenced, and can be taken quite a lot of time for defrost, defrost energy consumption accounts for the similar of entire energy consumption sometimes
One third or so, this steam latent heat for also having confirmed in air energy 35% or so are not utilized, and are favorably to increase originally
Effect thing but becomes harmful situation.If the steam latent heat in air will be turned bane into boon by solving worldwide defrost problem
, the Energy Efficiency Ratio of heat pump unit at least can be improved 25% or more by this.As heat source tower technology occurs, water chiller is transformed into
The case where defrost problem is not present in its evaporator of heat source tower heat pump unit, but there are frozen pipe breaking-up evaporators, because using
When anti-icing fluid is as heat transport fluid, it, which can absorb the steam in air in the case where temperature is lower than ambient temperature situations, leads to anti-icing fluid
Freezing point temperature moves up, and will lead to the generation of tube expansion event when evaporator temperature drops to the solution concentration freezing point temperature, therefore have
People, which uses the evaporating concentrating method lost more than gain, but causes Energy Efficiency Ratio to be greatly reduced, the energy that this can be much more than obtaining steam
It measures devaporation and anti-icing fluid is concentrated again why bother.There are also using based on the cold evaporation of negative pressure, it equally will cause cost of investment and increase, one
Sample difficulty prevents frozen pipe event from occurring, and there are also heated dilute anti-icing fluid using heat pump mode or solar energy method and be evaporated certainly
Concentration is all difficult to gather effect, these condensing modes not only depend on weather condition, also need to be equipped with biggish anti-icing fluid storage facilities,
Increase and also take up more space outside cost, and steam can lose after having got it in the same old way;Then just someone expects the second class mode
To prevent frozen pipe event from occurring, it appears that steam can be also utilized, but add anti-icing fluid constantly to prevent frozen pipe event from sending out
Life is to pollute water and soil as cost, and also it is difficult to ensure that operator does not neglect, if is ensured in defined concentration levels
Go down to add anti-icing fluid without causing frozen pipe event to occur.There is more appropriate mode to solve these problems, it is really effectively anti-
The technical solution that only frozen pipe event occurs has certainly: is exactly by existing maturation solution concentrated product, and in conjunction with overflow
Mode and liquid level controlling method recycle feedback heat energy and carry out negative pressure evaporation concentration anti-icing fluid, comprehensive multiple mature technologies
Scheme keeps operating cost lower, and operation is more reliable, and really steam can be enable lost and found again, it can makes anti-icing fluid concentration effect
Rate is improved, and steam can be enable really to be utilized, and this method is four to obtain at one stroke, and one must can obtain reality for steam
It utilizes, two must be that dilute anti-icing fluid temperature raising reduces negative pressure evaporation power consumption cost, and three must be the injection water temperature in condensation injection
Degree, which reduces, is more advantageous to vacuum degree raising and the evaporation of dilute anti-icing fluid and the condensation to steam, and four must be its whole-course automation, without
Operator's intervention, can must seem even more important completely to avoid the frozen pipe event caused by human negligence, the 4th, it can be true
It is positive to realize heat source tower commercialized running.
The heat source tower technology for the last century the nineties that originate from brings many dreams and money chance, somebody to the ranks
Had left from this ranks, but there is that more people come in or even many major companies are involved in into, be really it is very lively, it is preceding
Go to the ranks thus that subsequently pour in add lustre, hardly realizes that international corporation also starts to manage this part of field, include the country
Haier, TCL, their Gree etc. be eager to have a try, and overlooks this block cake, and bolter goes because technology is not really up to the mark sad,
Incomer attempts to share this part of economic interests in the future, this similar pioneer as many emerging developments ranks early period
It much falls down, continues trailer and see that either with or without superior technique scheme, what is finally achieved is that those really have Continuous Innovation energy
The people of power.Practical case not next thousand done, related invention and patent of invention are learnt from relevant departments' statistical data
There are tens, many cases bring bad impression to user, denounce the more, also there are many successful stories attract respectively certainly
Ground client.
So it is thought that be further improved to heat source tower technology, that is, utilize existing cooling tower progress adaptability
Transformation accomplishes that rainwater-proof, solution preservation improve, and to the elegant Resolving probiems of solution, anti-icing fluid is between evaporator and heat source tower
Run this anxiety for appearing not to defrost, but it can there is a problem of one it is new: be exactly anti-icing fluid because absorbing water in air
Its solution concentration of vapour can be thinning, this is because anti-icing fluid temperature is lower than ambient air temperature always, moisture in air is caused to condense
In anti-icing fluid, therefore freezing point of solution temperature can be made to move up, freezing point temperature moves up the copper pipe that will appear icing and swollen bad evaporator,
Cause huge economic losses.
This is swollen, and the commonplace case of bad copper pipe just becomes the maximum pain spot of this ranks.As a result expect using with regard to someone
Anti-icing fluid mode is concentrated to prevent anti-icing fluid freezing point temperature from moving up the appearance of situation, starts to evaporate using electrically heated rod at first dense
Contracting anti-icing fluid, as a result, it has been found that the energy that concentration anti-icing fluid consumes is huge, hence it is evident that lose more than gain, then abandon this concentration side quickly
Method, using addition anti-icing fluid mode come prevent swollen bad copper pipe event occur also just come into being, but will cause operation at
Originally it steeply rises, and to water and soil there is also pollution, environment measuring office will can intervene sooner or later.Very worry this ranks to be died young
Folding, and forfeit in these unpractical technical solutions, it can be strangled sooner or later by environmental protection administration.
Nevertheless, who is not desired to abandon the big cake of this block.Because there is the overall situation that current coal changes electricity or even gas changes electricity,
This is Future Development trend, it is clear that if heat source tower can solve anti-icing fluid freezing point temperature and move up problem, rather than uses addition anti-
Freeze the mode of liquid non-environmental protection to prevent freezing point of solution temperature from moving up, is replaced if anti-icing fluid mode is concentrated using inexpensive negative pressure evaporation
For conventional boiler heating will refer to day can to thing.
Existing heat source tower ranks produce a series of related invention patents, and the such invention of many correlations and patent of invention are in reality
There are also to be improved, solution corrosion plant issues during applying, and the elegant problem of solution, tube expansion problem and solution losing issue are all by phase
After being resolved.There is the people of judicious judgment foresight to see that the dawn at heat source tower dawn, huge energy-saving potential attract many relevant technicals
Worker goes to study.The mode of constantly addition anti-icing fluid can not continue down, because the method is still eliminated not
The hidden danger of frozen pipe, and water and soil can be polluted, also embarrassed its adds the cumbersome of anti-icing fluid to user, and operator also accomplish not dredge by difficulty
Suddenly, careless slightly and frozen pipe occur.And those using the calcium chloride person that does anti-icing fluid either with or without considering that solution corrodes equipment
Problem, 4 to five years scenes of equipment reach an end;And be corroded almost using urea as anti-icing fluid person equipment 5 to six years,
And it also has solution crystallisation problems and heat pump unit is caused to be unable to operate normally.Using traditional evaporation and concentration mode huge energy consumption
User is difficult to receive, and what concentration process consumed can even can be more than the energy that heat pump main frame consumes.It is using heat pump mode come dense
Contract dilute anti-icing fluid, or dilute anti-icing fluid is concentrated using solar energy, or is based on the wet evaporation of negative pressure, these not only increase
The cost of investment of solution concentrator, its same concentration process pay energy consumption cost be also it is very high, steam can be also in air
Can not really be utilized, all this kind condensing mode, all be that steam can be lost after having got it, without greater advantages with it is air-cooled
Heat pump unit is compared, because these anti-icing fluid condensing modes are all that steam can be discharged in air again in a gaseous form
, and only really steam can be used by being discharged in a manner of condensed water to be only, this just cries lost and found again concentration side
Formula.Some region steam can also account for entire 35% or more air energy, if heat pump unit can improve 35% efficiency, how this is
Very difficult thing, with this just it is more advanced than air-cooled unit mostly, have a extensive future very.
The size of water capacity is different in each regional air, and the same time relative humidity from different places
Also it can change, southern region of China many bigger than northern area humidity, humidity was not only advantageous but also harmful to heat pump unit greatly, sees and adopts
It is handled with what technical method, can be obviously not used according to existing its steam of inverted running defrost technology, and
Become very harmful thing, using the heat source tower technology of no defrost, it appears that without defrost, can encounter on freezing point temperature in fact
Shifting problem, do not resolve freezing point temperature move up problem its harm can be bigger, directly result in evaporator copper pipe by swollen bad, cause huge
Economic loss.
We have to be understood that moisture content is how many in air thus, and steam absolute content is according to air in general air
The difference of evaporation capacity and temperature and change, absolute humidity from a ten thousandth to 1/40th change.Relative humidity is
The ratio of given temperature existing water vapor content and maximum water vapour content, relative humidity are given as percentages, variation range from
Heated dry air close to 0 to 100% fully saturated humid air, and there is water mist situation.We are it is understood that hot-air
More vapor can be carried than cold air.So even if absolute humidity (actual water vapour content) is identical, the phase of hot-air
Cold air will be lower than to humidity.Therefore, we can be by giving an air cooling-down to promote its relative humidity.If air quilt
It is cooled to sufficiently low temperature, relative humidity, which can achieve 100% and be saturated, condenses into cloud.This temperature is dew-point temperature.
When heat pump unit evaporator temperature drops to ambient dew point temperature, evaporator fin will condense, if under temperature continues
Drop will frosting, in fact condense when heat pump unit Energy Efficiency Ratio can be very high, this is highly advantageous to unit.When environment temperature is close
When zero degree, evaporator just will appear frosting, and heat pump unit efficiency can maximize when just having started frosting, can not only obtain gas
State becomes the latent heat of liquid, can also obtain liquid and become solid latent heat, not only lead evaporator when frost thickness gradually thickens this
Thermal efficiency decline, it is often more important that block air duct, intake, which is reduced, directly reduces heat exchange amount, so this is very harmful knot
Frost, solving worldwide defrost problem will make heat pump unit efficiency improve 25% or more.
We referring again to see 1,000,000 kilocalorie heat pump units on earth can how many condensed water be precipitated, unite according to authoritative institution's data
Count general air energy heat pump, some humidity biggish area average 25% or so in southern area that obtain in air steam latent heat
Up to 35% or more, opposite to reduce a lot in the north generally only has 15% or so.If it is exactly 250,000 that we are calculated by 25% accounting
Kilocalorie latent heat, and how many condensed water can be precipitated by discharging 250,000 kilocalorie heats, it is understood that water is in an atmospheric pressure (0.1MPa) 100
DEG C when the latent heat of vaporization be 2257.2kJ/kg, be 2484.1kJ/kg in 0.001Mpa, 6.9491 DEG C, 1 card=4.182 is burnt
Ear, then 1 kilocalorie=4.182kj, then 250,000 kilocalorie=250000 × 4.182kj=1045500kj, it is possible to condensation be precipitated
Water=1045500kJ/2484.1kJ/kg=420kg, for 1,000,000 kilocalorie heat pump units, we must configure concentration
Appliance arrangement can be concentrated per hour and be precipitated 420 kilograms of condensed water.It and is 5.5kw, model 2b-F111 water for power
Ring vacuum pump is 3800pa in vacuum degree, when solution temperature is 30 DEG C, 3.83 cubes of sucking rate per minute, and if the feelings for the vapour that draws water
47 cubes can be taken out under condition per minute, that is, sucking rate is 229.8 cubes of air per hour, when 45 DEG C of antifreeze liquor its
Gas phase vacuum degree is 95.8kpa, and gas phase is vapor, and the density of vapor is 0.06543kg/m at this time3, the vapour that draws water is per small
Shi Keda 6890m3/h.It is just corresponding higher to be primarily due to its higher gaseous phase partial pressure of solution temperature, water if being steam if what is aspirated
Vapour can condense in recirculated water, so its steam volume taken out can be 99 times of air or more, therefore can aspirate per hour
Steam is 451kg/h, is entirely the heat source tower that 1,000,000 kilocalories can be equipped with using 5.5kw water ring vacuum pump.According to water injection
Condenser pump model are as follows: PLB500, its vapour 500kg that can draw water per hour in absolute pressure 3066pa, institute are with circulation pump power
5.5kw, corresponding water-jet pump model are as follows: ZSWJ-100, under identical vacuum degree and jeting circulating water temperature conditions, if
It is directed to suction air, then aspiration per hour: 100/m3H, that is, 129kg/h, respective cycle pump power
It is 7.5kw, and 650kg/h steam can be aspirated if being used to aspirate secondary steam per hour, the quality for aspirating steam can be taken out
5 times of suck quality are shown if if calculating according to the water-vapo(u)r density under corresponding vacuum environment can be 99 times of volume of air
So suction steam has that institute is improper, and parameter will not be marked and be aspirated per hour for suction steam on general nameplate according to volume calculating
Steam how many cubic meter but per hour aspirate how many kilograms of steam because suction air and suction Water Vapor Quality and volume all can
Difference, reason, which is to be vortexed caused by shower edge, has volume to inhale water vapor effect, this many stronger than volume suck effect, by
Liquid water can be condensed into steam and recirculated water bonding tightness is significantly larger than the conjugation of air and water, be dissolved in than air
Shared volume is also much smaller in water, so vacuum degree when the vacuum degree at shower edge is than suction air when suction steam
It is big many, then speed when speed when suction steam will be than suction air is much larger, the part under corresponding vacuum environment
Hydrone and air can be escaped from recirculated water, and vacuum degree is higher, and escaped quantity is bigger, and the higher escaped quantity of circulating water temperature also can
It is bigger, when volume, which is inhaled, reaches dynamic equilibrium with evolution, the suction steam or ability of air that will be kept constant, if Entraining Effect
Being better than evolution effect so vacuum degree enhances, and suction capactity also increases, if jeting circulating water into injector temperature be more than 38
DEG C when, steam will constantly escape that injector at this time is just basic to lose suction capactity from recirculated water, and air escapes speed
It can be escaped than steam more quicker.Compare 250,000 kilocalorie heats consumed 5.5kw per hour, even if plus that may need to antifreeze
Liquid carries out the power that thermal compensation is warming up to 41 DEG C or more consumed 3000w, also just consumes 8.5kw, this efficiency per hour
Than almost reaching 34 times, that is to say, that anti-icing fluid is concentrated in the way of both and obtains steam latent heat in air
250000 kilocalorie=250000 × 1000/860=290.1kw can obtain 34 times of Energy Efficiency Ratio with the ratio between 8.5kw.It is assumed that anti-icing fluid from
It is 0 DEG C that evaporator, which comes out temperature, and circulating water temperature is 45 DEG C, and the dilute anti-icing fluid being concentrated is 200kg, and recirculated water is
250kg, water ring vacuum pump or spraying cycle pump work can make 45 DEG C of recirculated waters enter in feedback heat energy heat exchanger with it is another
Dilute anti-icing fluid of side carries out thermal energy exchange, and temperature just drops to 20 DEG C or so when recirculated water goes out feedback heat energy heat exchanger, and dilute antifreeze
Liquid is just constantly increased to 20 DEG C or more from 0 DEG C, since water ring vacuum pump or jet condenser pump operation are mass-and heat-transfers while carrying out
, although recirculated water partial heat is transferred to inside dilute anti-icing fluid, dilute anti-icing fluid water evaporation can take away part again
The heat of dilute anti-icing fluid, while again heat be transferred to recirculated water again and suffered, lead to condensation injector out or out Water-ring vacuum
The circulating water temperature of the exhaust pipe of pump increases 15 DEG C or more, then recirculated water goes out 20 DEG C of feedback heat energy heat exchanger, to arrive out water ring again true
35 DEG C will be increased to when sky pump or condensation injector, at this moment the temperature of cyclic water tank will be reduced slowly, be reduced to certain journey
Degree at most can only also make dilute anti-icing fluid temperature rise to 30 or so with regard to maintaining equilibrium state, it is therefore necessary to which circulating water temperature is mentioned
Height can just make dilute anti-icing fluid temperature rise to 41 DEG C or more to 45 DEG C or so, this is just conducive to the device efficient concentration anti-icing fluid,
So cyclic water tank inner heating device may work as recirculated water and provide heating heat, it is therefore necessary to heat up, and lead to recirculated water
Cross solution heat cycles pump constantly dilute anti-icing fluid squeeze into feedback heat energy heat exchanger with recirculated water carry out heat exchange, heat
Also it is recycled.Because dilute anti-icing fluid is in 20 DEG C or less its evaporation capacity meeting very littles, required vacuum degree is also relatively high,
Therefore it must further heat up to dilute anti-icing fluid.Another mode be exactly use electrically heated rod or from heat pump unit condenser and
The hot fluid come is that dilute anti-icing fluid directly heats, although which does not need solution heat cycles and pump, but its heating speed
It spends relatively slow.Best bet be to circulating water heating, then by spraying cycle pump or water ring vacuum pump following after heating
Ring water, which is constantly delivered in feedback heat energy heat exchanger, to be exchanged with the other side by dilute anti-icing fluid that solution heat cycles pump is called in
Heat.If from evaporator come out dilute anti-icing fluid temperature at -15 DEG C or less, it is necessary to be equipped with 45 DEG C of recirculated water 300kg be directed to -
15 DEG C of dilute anti-icing fluid of 200kg heat up, and heating device size and 0 DEG C of anti-icing fluid configuration almost can be with, only solution
The heat cycles pump circulation time is more relatively long.If out the anti-icing fluid temperature of evaporator be higher than 5 DEG C, may result in into
The circulating water temperature for entering condensation injector or water ring vacuum pump is higher than 30 DEG C, and when the recirculated water of injector is higher than 45 DEG C out, just
Must be taken into consideration reduces circulating water temperature, and the cooling device for reducing recirculated water must be arranged, because recirculated water goes out feedback heat energy heat exchange
Its evacuation becomes more and more difficult when device temperature is higher than 30 DEG C.
The related anti-icing fluid concentration patent applied thus has very much, is compared analysis with regard to citing here, they have:
A kind of " steam energy latent heat feedback solution concentration systems " (patent No.: 201810863778.3);" a kind of steam energy latent heat feedback is molten

Condensation injector is only almost pumped composed air extractor with spraying cycle with above-mentioned patent set meal principle and process to change
It is same not account for exhausting problem for water ring vacuum pump, do not account for carrying out for dilute anti-icing fluid yet thermal compensation and
It is pumped using setting solution heat cycles to improve dilute anti-icing fluid temperature and accelerate its evaporation rate, is not also accounted for for recirculated water
Cool down to improve vacuum degree or improve the efficiency of condensing water vapor.These early periods although applied patent of invention has one to be total to
Property be exactly steam can it is lost and found again, but cannot achieve efficient concentration anti-icing fluid, regardless of use condensation injector vacuumize mode
Come realize anti-icing fluid concentration might as well, or use water ring vacuum pump negative pressure evaporation, efficient concentration is all short of very much,
That is when in the lower situation of environment temperature, anti-icing fluid temperature also can be very low, using negative in the lower situation of anti-icing fluid temperature
Its vacuum level requirements of pressure evaporation and concentration are very high, the water ring vacuum pump under higher vacuum, or condensation liquid-jet vacuum pump
, many energy penalties will be all paid, equipment sealing performance will also enhance, so only with feedback heat energy mode to dilute
Anti-icing fluid heating is inadequate.The invention patent promotes anti-icing fluid using fluid heat in electrically heated rod or condenser thus

Recycle, and the anti-icing fluid of above-mentioned comparison concentration related invention patent is not just in this way, and they only just for opening
Formula heat source tower is not accounted for docking closed type heat source tower and carrys out defrosting, do not account for more being risen using dilute anti-icing fluid endless form
Temperature.
Existing closed type heat source tower is exchanged heat using the wide small temperature difference of fin, and the relevant technologies are the same also to encounter fin frosting problem, this
Fin heating conduction can be seriously affected, heat pump unit is resulted even in and is unable to operate normally, removes the fin that melts away according to anti-icing fluid
On frost, also result in anti-icing fluid freezing point temperature and move up problem, it still can encounter the dilute anti-icing fluid problem of concentration, and use addition
The method of dense anti-icing fluid be absolutely it is worthless, tradition be concentrated by evaporation anti-icing fluid it is obviously less cost-efficient, even with heat pump mode
The low-temperature antifreeze liquid gone inside heating closed type heat source tower heat exchanger may require that for a long time just can be low-temperature antifreeze liquid temperature liter
To more than zero degree, and need to stop heating work, anti-icing fluid temperature can be lower than -20 inside the north sometimes heat source tower heat exchanger

It is that anti-icing fluid content volume increases process, this increases capacity can be handled using overflow manner, and dilute anti-to what is overflowed
Freeze liquid to be individually concentrated;
And heating can carry out with enriching service simultaneously, it does not need to carry out all anti-icing fluid in concentration process
Heating, therefore it can be considerably less that institute's heat dissipation, which is concentrated, and the dilute anti-icing fluid overflowed is to enter directly into feedback heat energy heat exchange
In device, rather than antifreeze liquor is distributed using liquid inventory control valve or conversion system how much enter feedback heat energy and change
In hot device, this facilitates automatic control easy, can greatly reduce the source of trouble.
Its default control evaporating temperature also wants much more accurate, and anti-icing fluid fluctuation of concentration range is also much smaller, it is not
Feedback heat energy heat exchanger is seated in negative pressure evaporation room 4, is changed because feedback heat energy heat exchanger is put interior its in negative pressure evaporation room 4

It is constantly dilute anti-icing fluid heating heating recirculated water heat.
Fifth, existing correlation anti-icing fluid concentration technique does not account for, circulating water temperature is excessively high to will lead to Water-ring vacuum pump circulation
Water cannot achieve sealing, equally also result in water injection condenser pump since spraying cycle coolant-temperature gage is too high to vacuumize, shadow
It rings to the effect that dilute anti-icing fluid is concentrated.
