Description
Technical field
The utility model relates to evaporating type condensing, cooling technology, particularly relate to evaporating type condensing and cooling device with demister, can avoid evaporating type condensing and cooling device in the process of carrying out condensation or cooling, to discharge saturated vapor, eliminate in the device surrounding environment and cause the water smoke pollution problems.
Background technology
In the middle of condensation and cooling technology, often cooling device (as: cooling tower) and condensing unit (as: condenser) are used in combination, its principle is to utilize cooling medium and the temperature difference between the medium of being cooled, and carries out the purpose that the caloic exchange makes be cooled medium cooling or condensation by heat exchanger.For example in refrigeration, air-conditioning system, the high pressure superheater refrigerant gas in the condenser is the relatively low cooling water of heat transferred temperature, and cold-producing medium itself is condensed into high pressure refrigerant liquid; Behind the heat of cooling water absorption refrigeration agent in this process, temperature raises, then by cooling tower with the heat transferred atmosphere, enter the agent of condenser cooling refrigeration again after the reduction of the temperature of cooling water itself, thereby realize continuous cooling, the purpose of condensation.The effect of cooling tower is that recirculated cooling water is cooled, and cooling tower commonly used has dry cooling tower and wet cooling tower.As the common heat exchanger of another kind, the effect of condenser is that gaseous matter is condensed into liquid state, and condenser commonly used has water cooled condenser and various air cooled condensers such as closed shell and tube condenser, open shell and tube conde er.
Evaporating type condensing and cooling device can be thought the composite set of wet cooling tower and condenser, its principle is that cooling water is sprayed at heat exchanger surface equably, and at heat exchanger surface formation moisture film, take away the heat of heat exchanger interior media by the evaporation of heat exchanger surface moisture, thereby the gas medium that the heat exchanger internal temperature is higher is condensed into liquid (perhaps high-temp liquid cools), and the saturated vapor after the evaporation is discharged to the ambient air of device outside by air exhauster.Can in time be taken away by air exhauster in order to ensure the steam after the evaporation, guarantee its heat exchange efficiency, the wind speed by heat exchanger should be as far as possible near 4m/s, in this case, just have large quantity of moisture with the form of water droplet with saturated vapor discharged to ambient air.Therefore, circulation is internally gone up and is analyzed, the formation of evaporating type condensing and cooling device water smoke comes from two aspects, and the one, the water smoke that the water droplet of carrying secretly in the saturated vapor discharged to atmosphere forms, the 2nd, saturated vapor solidifies droplet and forms water smoke in colder surrounding air.But, because the sleet in the sleety weather environment also can enter evaporating type condensing and cooling device from the exhaust outlet of blower fan, thereby formed water smoke discharged to atmosphere.Although on energy-conservation angle, evaporating type condensing and cooling device have the effect of highly significant, but the existence of water smoke problem causes very serious pollution to environment, therefore, evaporating type condensing and cooling device in use are very restricted, and cause it to fail to replace other power consumption serious condensation and cooling device in a lot of fields.
In order to eliminate this water smoke phenomenon, the insider is making great efforts always for it, a lot of reductions have also been arranged or reduced the solution that water smoke generates in evaporating type condensing and the cooling device running, but these schemes all fundamentally do not solve the water smoke pollution problem of evaporating type condensing and cooling device.
In US Patent No. 2882996, the wind deflector that take on heat exchanger top, the blower fan bottom is provided with the oblique layout of multi-disc multilayer, the water droplet of carrying secretly in the saturated vapor under the high speed wind speed is separated, and will stop that by the guiding of oblique layout wind deflector the current that get off return the evaporating heat exchanger of bottom.Because the evaporating heat exchanger of this patent adopts high wind speed, and the actual internal area of the wind deflector wind speed of the oblique layout of multi-disc multilayer is much smaller than the sectional area of bottom heat exchanger, the wind speed at wind deflector place will be far above the wind speed of bottom heat exchanger, thereby only some water droplet of carrying secretly up with the high speed water steam can be excluded, can not make with the water droplet of carrying secretly in the high speed water steam and separate fully, after the wind deflector dehydration through the oblique layout of multi-disc multilayer, character and the state of saturated moist steam do not change.Therefore, the scheme that this patent discloses has just played and has reduced or reduced the water smoke discharging in the running, and the generation that can not thoroughly solve water smoke.
In the disclosed cooling tower of BP G845844, the finned heat exchanger of two groups of series connection is up and down arranged, last group is located at the top that is close to spray thrower, and group is located at the below that is close to spray thrower down, though wherein mentioned last group heat exchanger except cold-producing medium having been carried out also have the precooling function of demist, but, owing to guarantee that the heat exchange efficiency of group evaporating heat exchanger needs very high wind speed (US Patent No. 2882996 also confirms this point) down, inevitable some water is taken away by the high speed water steam, and because the air quantity of blower fan is certain, the sectional area that has group heat exchanger under the path of saturated vapor process of water droplet, the sectional area of last group of heat exchanger and the sectional area of organizing up and down between the heat exchanger equate, namely the speed that has a saturated vapor of water droplet through this three place equates, be in fast state, in this case, the water droplet of carrying secretly in the saturated vapor will enter the group heat exchanger with the high speed saturated vapor, and relative humidity can reduce to some extent after saturated vapor absorbed heat through last group of heat exchanger.But in fact, because wind speed is too high, heat exchanger time is very short, and the water droplet with the high speed water steam is carried secretly can not evaporate fully, water droplet is still arranged discharged to atmosphere, directly forms water smoke; And, behind last group of heat exchanger of saturated vapor process, though relative humidity will be very little, but be not eliminated fully with the water droplet that saturated vapor is carried secretly, in other words, leave the gas-liquid two-phase body that the upper fins coil pipe remains water, radical change does not take place in the state of saturated vapor and character, still the problem that steam is met cold generation water smoke can occur.At sleety weather, after sleet entered cooling tower, because self tension force of water, this part water will remain between the fin of organizing heat exchanger, and therefore, this part water also will be as water smoke by discharged to atmosphere.Therefore, go up the function that the group finned coil carries out demist though this patent has designed to utilize, its water smoke discharged to atmosphere alleviates to some extent or alleviates than the cooling tower of not going up the group heat exchanger really, does not eliminate discharging and the pollution problem of water smoke.
In No. 200920121308.6 described cooling tower of Chinese utility model patent, below blower fan, also be provided with a kind of and the consistent demister of tower case inner section shape, steam pipe coil by hollow is formed, can be provided with radiating fin on the coil pipe, but employed high-temperature steam is provided by independent high-temperature steam source in this demister, and the wind speed of its fixed position still wind speed with the cooling heat exchanger position of hypomere is identical, thus the demister of this cooling tower there are the following problems:
1, need corresponding auxiliary facility, increase additional energy consumption, from environmental angle, energy-conservation, reduction of discharging that this demist mode can not realize;
2, the wind speed that is used for the steam pipe coil of demist owing to wind speed and process through the space between bottom heat exchanger and the steam pipe coil equals to take away the needed high speed wind speed of bottom heat exchanger surface water evaporates, therefore, the cooling medium that enters the demist steam pipe coil with the wind remains the saturated vapor of carrying a large amount of water droplets secretly, although the temperature of steam pipe coil is higher, but, because speed is very fast, the saturated vapor that causes carrying secretly a large amount of water droplets is very short at the heat-exchange time of steam pipe coil, the water droplet of carrying secretly in the saturated vapor can not be evaporated fully and become unsaturated steam, also just can't eliminate the water smoke problem of this cooling tower;
Therefore, though this patent may be more better than disclosed device among the aforementioned BP G845844 except fog effect,, still do not solve the water smoke problem of cooling tower fully, and, power consumption disclosed device in the BP G845844.
In authorizing No. 200620119378.4 described antifreezing and fogging water-saving cooling tower of Chinese utility model patent of Tsing-Hua University in 2007, top and the bottom sidewall at the cooling tower body is respectively equipped with air inlet up and down, air inlet is provided with shutter, be furnished with first, second aerial cooler respectively in the inboard of air inlet shutter up and down, between first aerial cooler of both sides, be provided with a water collection device, spray equipment then is located at first aerial cooler below, the top of second aerial cooler, the below of spray equipment is provided with the PVC packing layer.This cooling tower utilizes first aerial cooler that recirculated water is carried out precooling, has reduced the cooling load of packing layer, also because having reduced the evaporated water using water wisely; Utilize second aerial cooler to increase the cooling load of recirculated cooling water in aerial cooler again, improved water saving efficiency, and play pre-heat effect to advancing the tower air, can effectively prevent freezed in winter, and the air-flow that goes out tower is the mixture that first aerial cooler and water collection device are worked off one's feeling vent one's spleen, its dew-point temperature is less, thereby eliminates or reduction tower saliva mist.But, this patent adopts the mode of mixing through the saturated vapor of carrying water droplet secretly that produces in the cooled air of first aerial cooler and the second aerial cooler cooling procedure of taking away with high speed winds to reach the purpose of falling mist, but in fact owing to the saturated vapor of carrying water droplet secretly is high wind speed, after air that first aerial cooler comes out mixes, wind speed can be higher, the two heat of mixing exchange can not be fully, and therefore the gas of discharging still has the water smoke problem; And it is very big with environmental change through its state of air of first aerial cooler, in the environment cloudy, that the greasy weather equitemperature is lower or relative humidity is bigger, temperature, humidity through the air of first aerial cooler are also very big, and in this case, the generation of water smoke is still inevitable.
The evaporative condenser of prior art is to utilize water pump the water in the water leg to be transported to the spray equipment at top, spray the condenser coil outer surface through nozzle and form very thin moisture film, be evaporated to steam after the heat absorption of part water in the moisture film, the heat of water high-temperature gas cold-producing medium in when evaporation absorption condensation coil pipe and make the cold-producing medium in the condenser coil be condensed into liquid state by gaseous state, all the other do not evaporate and the water do not taken away with the high speed saturated vapor falls into water leg for recycling.Traditional evaporative condenser mainly is made up of parts such as casing, condenser coil group, PVC filler, spray equipment, blower fan, water leg, water pump, water-flow circuit, mist elimination devices.The axial flow blower forced air is inhaled into the coil pipe of flowing through from top and lower sidewall, filler, saturated hot humid air then are discharged in the ambient atmosphere, the part water droplet of carrying secretly in the hot humid air is held back by water collection device, can control a part of water droplet and fly away loss, owing to steam and part water droplet scatter and disappear cause the part water yield of lose in the atmosphere in system by the additional cooling water of ball-cock assembly control.
In having described a kind of No. 200320107044.1 utility model patent of existing evaporative condenser technology, one side of casing has been arranged heat exchange layers, header tank and the water circulating pump that spray water system, condenser coil group, PVC filler plate constitute from top to bottom, in casing opposite side be provided with following dehydrator (water fender) corresponding to the PVC filler plate, corresponding to the last dehydrator (water fender) of condenser coil group and be arranged on finned cooling tube group below the blower fan.The air inlet of this fin cooling tube group links to each other with the compressor refrigerant outlet, and its gas outlet links to each other with condenser coil group air inlet.The hot humid air that this utility model utilization is risen runs into fin cooling tube group the cold-producing medium in the pipe is carried out precooling, make cold-producing medium (ammonia) temperature that enters the condenser coil group reduce 20-25 ℃, delayed the fouling time of condenser coil effectively owing to the reduction of refrigerant temperature, operating efficiency and the life-span of equipment have been improved, also effectively shower water is used through the hot humid air that distributes after condenser coil group and the PVC filler plate simultaneously, makes overall efficiency be improved 15%.Yet such evaporative condenser has following problem:
1, condenser coil air inlet and blower fan exhaust outlet are in the same side, and short circuit phenomenon appears in high temperature saturated vapor and the condenser coil air intake that will cause blower fan to be discharged like this, thereby has improved the condensation temperature of condenser coil;
2, in the flow direction of condenser coil air-out direction and cooling water always, be unfavorable for that cooling water evenly distributes and the foundation of moisture film, water consumption is relatively large;
3, because condenser coil is taken away in the condensation process and to be produced the saturated vapor that has moisture content and need high wind speed, so just cause saturated vapor wind speed after leaving water fender of entrapped moisture higher, static pressure is also bigger, in this case, from not flashing to saturated vapor and bigger by the air quantity of the saturated water of being taken away by water vapour after the bottom air intake is used for the cooling condensation coil pipe, its static pressure need be higher than the top static pressure, the saturated vapor of carrying water droplet secretly that the bottom cooling water is formed, after the saturated vapor of the formed water entrainment of top condenser coil passes through finned coil by blower fan discharged to ambient air, therefore, from the configuration of wind system, this evaporative condenser is not energy-conservation;
4, the dewatering efficiency of all water fenders can not be 100%, especially dewatering efficiency is lower under the state of high wind speed, therefore, although this evaporative condenser has been installed two water fenders up and down, but, still the water that contains significant proportion through the saturated vapor after the water fender, and two strands of saturated vapors that contain moisture are at the top water fender port of export, be that the speed of the bottom of finned coil is at least the twice through the wind speed of condenser coil, in this case, separating can not appear in the water droplet of saturated vapor, must enter finned coil with saturated vapor, because wind speed is too high, heat-exchange time is too short, and therefore, this finned coil has just absorbed the moisture of carrying secretly in a part of saturated vapor and the saturated vapor, final carry the saturated vapor of water droplet through blower fan secretly discharged to remaining of atmosphere, the water smoke problem that produces in the running still exists.
As described above, the technical problem that exists in the prior art and defective, present cooling tower and evaporative condenser can only be to reduce or reduce the water smoke problem that produces in the running, still can not fully solve and eliminate water smoke problem that the outlet of blower fan in the running produces and because of the generation pollution on the environment of water smoke problem, and the shortening that causes the service life of equipment, to cause pollution to environment and cause Legionella by this water smoke in company with the propagation of fog, health will be produced serious threat.In addition, because this water smoke that evaporating type condensing and cooling device produce also can cause corrosion to miscellaneous equipment, thereby has to be installed separately with miscellaneous equipment, cause the complexity of whole system to improve and the increase of initial outlay expense.And in cold area, particularly temperature is lower than under the subzero situation in the winter time, and these water smokes can form frost at the air outlet that goes out cooling tower, cause the damage to equipment.
Therefore, demand a kind of new technology that can thoroughly solve the problems of the technologies described above really urgently, thoroughly eliminate the various harm that the water smoke problem is brought, to break evaporating type condensing and the cooling device limitation on using.

Below we with reference to the embodiment of above-mentioned first kind of evaporating type condensing cooling device, specify above-mentioned evaporating type condensing and the applied system of cooling device of using, for example refrigeration, air handling system etc., carry out condensation and the operation principle when cooling off:
The medium that is cooled that needs condensation or cooling (superheated steam or high-temp liquid) that aforesaid system gives off enters from the high-temperature medium entrance 311 of second heat exchanger 31, carry out after the precooling through second evaporating heat exchanger 31, superheated steam is cooled into saturated gas or has the high-temp liquid cooling that is cooled to go forward side by side into the evaporating type condensing/cooling unit 20 of casing 10 hypomeres.The medium that is cooled is undertaken in the middle of the process of caloic exchange by evaporating type condensing/cooling unit 20, the surface that water is sprayed at the condensation of first heat exchanger 26 or cooling coil uniformly by spray equipment 27 forms moisture film and flows down along the surface of this first heat exchanger 26, and this first heat exchanger 26 of flowing through be cooled medium with produce the caloic exchange along the moisture film on these first heat exchanger, 26 surfaces by convection current and the way of contact, wherein a part of water evaporates in the caloic exchange process and becomes saturated vapor and take away evaporation latent heat and the medium that is cooled is carried out evaporative heat loss, saturated vapor is then upwards taken away from the air-flow than low velocity of air-inlet grille 25 suctions of casing 10 hypomere both sides air inlets by axial flow blower 40, its air velocity is about 3m/s or lower, when air-flow during through first heat exchanger 26, because aisle spare narrow but air velocity suddenly rises, and for example reaches about 4m/s.The saturated medium that is cooled of first heat exchanger, 26 inside of flowing through then is cooled and is become saturated liquid or dropped to lower temperature by higher temperature by condensation of gas, finally by cryogenic media outlet retrieval system.Cooled off the saturated vapor of unit 20 generations by above-mentioned evaporative condenser under the high velocity air guiding, dehydrator (water fender) 50 by evaporative condenser/cooling unit 20 tops, enter the plenum chamber 12 of casing 10 epimeres, the moisture that dehydrated device 50 stops and part are stayed the then landing downwards of moisture that is not evaporated on the serpentine coil of first heat exchanger 26 or is taken away by high speed water steam, mix with the air enter casing 10 from air-inlet grille 24 in, temperature reduces after the exchange of contact caloic, and is final unrestrained to continue to participate in the cooling water circulation in the header tank 21 of casing 10 bottoms.
Next, still utilize the embodiment of above-mentioned first kind of evaporating type condensing cooling device, illustrate the evaporating type condensing that the utlity model has demister and the demist principle of cooling device.The effect that the plenum chamber 12 of casing 10 epimeres plays is to make the high velocity air of rising drop to about 2.5m/s or lower fast from the speed of about 4m/s.Saturated vapor and the water droplet thereof brought up from the hypomere of casing 10 along with ascending air, after leaving first heat exchanger 26 of casing 10 hypomeres, under the situation that is provided with dehydrator (or water fender) 50, at first separate the water of a part by stopping of dehydrator (or water fender) 50, these water can continue landing downwards enters casing 10 for water droplet hypomere along the edge of dehydrator 50; And enter plenum chamber 12 by the saturated vapor rising of carrying the part water droplet after the dehydrator 50 secretly, because channel cross-sectional area and the volume sudden enlargement of plenum chamber 12, make the speed of ascending air be dropped rapidly to about 2.5m/s or lower, at this moment the part water droplet will be separated from saturated vapor substantially, drops on the following dehydrator 50 or directly trickles down on first heat exchanger 26 of casing 10 hypomeres.When having carried out second heat exchanger 31 by casing 10 epimeres of saturated vapor that water droplet separates through plenum chamber 12, basically speed distributes equably and enters between the fin heat exchange pipe of second heat exchanger 31, make and realize between saturated vapor and this second heat exchanger 31 contact the caloic exchange fully and evaporate wherein part moisture, thus make enter plenum chamber 12 afterwards the saturated vapors by this second heat exchanger 31 flash to temperature and relative humidity all close to the gas of ambient air.
Shown in the example among Fig. 1, this wind deflector 32 will be from the saturated vapor of carrying water droplet secretly of casing 10 hypomeres rising, by change the direction that is 40 ° of left and right sides angles with vertical direction into along the vertical lifting direction.After the saturated vapor of carrying water droplet secretly enters primary droplet Disengagement zone 121, because the sudden enlargement of channel cross-sectional area and volume, its speed obviously reduces, and at this moment a water droplet will be separated, trickle down on first heat exchanger 26 of casing 10 hypomeres, continue to participate in evaporative condenser, cool cycles; There is not separated water droplet then still along with saturated vapor rises by wind deflector 32.Because the air intake direction of wind deflector 32 and air-out direction are the angle about 40 °, the water droplet of carrying secretly in the saturated vapor will be agglomerated into bigger water droplet at wind deflector 32, these water droplets are under the effect of himself gravity, down the wind deflector 32 glides and trickles down on first heat exchanger 26 of casing 10 hypomeres, continues to participate in evaporative condenser, cool cycles.
Yet, because the ability of the coalescent water droplet of wind deflector 32 can not be fully, therefore, leave and still carry the trickle water droplet particle of a part in the saturated vapor of wind deflector 32 secretly, after entering secondary water droplet Disengagement zone 122, because the aisle spare of secondary water droplet Disengagement zone 122 and volumetric ratio primary droplet Disengagement zone 121 is bigger, and enter secondary water droplet Disengagement zone 122 and carry the direction of the saturated vapor of fine particle water droplet (wind deflector air-out direction) secretly and almost be 90 ° of angles with the direction (i.e. the air intake direction of second heat exchanger) of leaving secondary water droplet Disengagement zone 122, thereby air velocity further is reduced to 2m/s, trickle water droplet in the saturated vapor that enters secondary water droplet Disengagement zone 122 is effectively separated again, thereby guaranteed that the air-flow through second heat exchanger 31 in the casing 10 epimere plenum chambers 12 is saturated vapor, the water droplet process wind deflector 32 that separates is trickled down first heat exchanger, 26 surfaces at casing 10 hypomeres, continues to participate in cooling, condensation cycle.
Because secondary water droplet Disengagement zone 122 has reserved sufficient space for the heat exchange area that is arranged at second heat exchanger 31 in the plenum chamber 12, the speed of saturated vapor through second heat exchanger 31 in the plenum chamber 12 time is about 2m/s, and saturated vapor just can have time enough and second heat exchanger 31 fully to carry out heat exchange like this.Because once, secondary water droplet Disengagement zone 121,122 existence, reduced the dynamic pressure of saturated vapor effectively, increased the static pressure of saturated vapor, saturated vapor can speed be distributed equably to be entered between the fin of second heat exchanger 31, air velocity evenly and do not have a dead angle, thereby fully ensured contacting between saturated vapor and second heat exchanger 31, guaranteed the effect of caloic exchange, make the saturated vapor of separating by plenum chamber 12 through second heat exchanger 31 time, fully evaporation becomes the gas close to ambient air temperature and relative humidity, thereby has solved that water droplet forms that water smoke and saturated vapor are met the condensation knot by discharged to atmosphere the time by discharged to atmosphere the time and the problem that produces water smoke.

Though among all embodiment in the foregoing embodiments, casing top in evaporating type condensing of the present utility model and cooling device is provided with axial flow blower 40, but be understandable that, the setting of blower fan 40 with steering current from the air-inlet grille 25 of casing 10 hypomere both sides air inlets first heat exchanger 26 by evaporating type condensing and cooling unit 20, water fender 50, plenum chamber 12, demister 30, second heat exchanger 31 of 30 ＇, 31 ＇, and the discharge of the air outlet at casing 10 tops is purpose, and no matter be to use the exhausting formula still to descend blowing-type, no matter be to use an independent blower fan also to be to use many typhoons machine.Among a kind of embodiment as shown in Figure 4, plenum chamber 12 tops of casing 10 epimeres also are provided with an independent blower fan 40, the places different with the embodiment of front are, the air-out direction of this blower fan 40 is consistent with the oblique air-out direction that is arranged in second heat exchanger 31 in the plenum chamber 12.
In sum, has following significant advantage according to evaporating type condensing and the cooling device with demister of the present utility model.
1, reduced the rate of climb of the saturated vapor of carrying water droplet secretly of spontaneous evaporation condensation and the generation of cooling unit by the structural design of plenum chamber, effectively carried out the steam separation, water by evaporation section the saturated vapor of second heat exchanger after separating steam of demister, thereby discharge is consistent with environment temperature and relative humidity, and because the existence of plenum chamber, even at sleety weather, the high velocity air of also having avoided tension force owing to water droplet that water droplet in the access to plant can not be landed voluntarily instead being produced by blower fan forms the problem of water smoke discharged to atmosphere; Thereby thoroughly having eliminated the water smoke that causes the Legionella growth and propagate generates and emission problem.
This device design condensation and chilling temperature≤35 ℃ are lower than 37 ~ 41 ℃ the water that Legionella is liked, therefore, and no Legionella generation problem in the device running; Because the cooling medium of device discharging is the state parameter close to ambient air, therefore, the propagation problem of no Legionella in this device running.
2, energy-conservation embodiment:
From the overall embodiment of front as can be seen, what the evaporative cooling heat exchanger of this energy-conservation no mist type evaporating type condensing and cooling device epimere used is the saturated vapor that hypomere evaporative condenser and cooling heat exchanger produce at heat transfer process, and by epimere evaporative cooling heat exchanger superheated steam is cooled to saturated gas, perhaps the temperature of high-temp liquid is effectively reduced, this part heat accounts for 20 ~ 30% of the total heat exchange amount of device, that is, the thermic load of hypomere evaporative condenser and cooling heat exchanger reduces 20 ~ 30%, because the quantity of circulating water of evaporative condenser and cooling device, air circulation all is to calculate for foundation according to hypomere evaporative condenser and cooling heat transferring amount, make this device quantity of circulating water, the more conventional evaporative condenser conserve energy of air circulation consumes 20 ~ 30%, the evaporation capacity saving amount of recirculated water is more than 25%, therefore, this device has the energy-saving effect of highly significant.
3, embodiment efficiently:
Version+top evaporative cooling heat exchanger that unique two-stage water droplet separates plenum chamber is in the shape of the letter V and oblique type arrangement form, the wind speed of two heat exchanger processes is inconsistent about having realized, on the one hand, guaranteed that bottom evaporative condenser and cooling heat exchanger need in time take away the needed 4m/s high speed of the saturated vapor that produces in caloic exchange process wind speed, on the other hand, wind speed through the top heat exchanger is heat and the air flow rate proportioning that 2m/s belongs to economical operation, and the cooling medium of epimere evaporative cooling heat exchanger is the waste gas that produces in hypomere evaporative condenser and the cooling heat exchanger heat transfer process, in addition, mounting heat exchanger uses can reduce the temperature of the media outlet liquid that is cooled effectively and make it in summer and has certain degree of supercooling in the header tank, for refrigeration, the employed evaporative condenser of field of air conditioning, can reduce the generation of flash gas effectively, therefore, this device has very high heat exchange efficiency.
4, delay the loose embodiment of being convenient to clean of fouling time and dirt:
The time of fouling of heat exchangers and the loosening degree of dirt depend primarily on the temperature of the medium that is cooled in the heat exchanger, and the more low fouling time of temperature, approximately slowly the fouling degree was more light, and dirt is more loose.Generally, what evaporating type condensing and cooling device fouling were the most serious is that moisture is sprayed at the heat exchanger that the surface forms the water film evaporation heat exchange, because steam cleans than water, often structure situation is low weight by the transpiration-cooled heat exchanger of steam, for this device, the fouling of hypomere evaporative condenser and cooling heat exchanger should be the emphasis object of prevention, yet, hypomere evaporative condenser and cooling heat exchanger condensation temperature at this device are 35 ℃, in other words, cooling water only is 35 ℃ in the evaporating temperature of this heat exchanger, and therefore, this device has the characteristics being convenient to clean after fouling time and the fouling of delaying.
