Specific embodiment
About the present invention to reach above-mentioned application target and effect and the technological means for being used, now with Fig. 1
(remaining air cooler body shape is ability as a example by the three-level spray humidification air cooler of air cooling tube bank horizontal series connection
Field technique personnel's conventional shape, the difference is that the application uses multi-stage spray form, as illustrated in figs. 2-7), and
Coordinate shown in accompanying drawing, details are as follows：
Three kinds of flow of media are had in air cooler, respectively：Thermal medium, air, spray water, wherein hot Jie
Matter is restrained 2 and sequentially passes through two grades of air coolings tube banks 5, one-level air cooling again by thermal medium inlet 3 into three-level air cooling
Tube bank 7 eventually passes through cold medium import 8 and goes out air cooler, and air has air inlet 10 to enter air cooler inside process
7, two grades of air coolings tube bank 5, three-level air cooling tube banks 2 of one-level air cooling tube bank eventually pass through blower fan 1 and discharge, and spray
Water reaches absorption during sprayer units at different levels run in air by spraying pump group 13, atomizer passgae 12
Heat in air carries out constant enthalpy evaporation, and air themperature reduction, humidity increases, and the constant wet-bulb temperature of enthalpy is not
Become, but enthalpy increases during air and air cooling tube bank heat exchange, and wet-bulb temperature is raised, humidity reduction.
Be cooled to fresh air close to wet-bulb temperature after the atomization of one-level sprayer unit 9 by water, the air after cooling with
Again through two grades of humidifying coolings of sprayer unit 6 to close to wet-bulb temperature after the heat exchange of one-level air cooling tube bank 7, after cooling
Again through the humidifying cooling of three-level sprayer unit 4 to close to wet-bulb temperature after being exchanged heat with two grades of air cooling tube banks 5, lower the temperature
Exchanged heat with three-level air cooling tube bank 2 afterwards, the cooling to medium is realized by said process.
Wherein, the wet-bulb temperature of air does not increase too much after one-level spraying and one-level air cooling, two grades of humidifications
Air themperature still can be down to close to wet-bulb temperature (this requires that atomized water has enough stopping in atmosphere
Time or nozzle and tube bank is stayed to keep enough distances, specific distance is by spray flux density, particle size, head-on
Wind speed, local environmental conditions are relevant, and the direction of spraying is preferably the direction towards windward side, so makes atomization
Water come and go in atmosphere one section make its in atmosphere the residence time increase), similarly three-level humidification still can be by
Air themperature is reduced to close to wet-bulb temperature, the series of humidification do not fix, it is necessary to according to local ambient air temperature,
The temperature grade of wet-bulb temperature and medium determines that the resistance of blower fan and the height of air cooler can be with air cooling pipe
The increase of the beam number of plies and increase.
Form citing of the present inventor to invention data herein is further described to it, such as in Xinjiang
Regional air enters empty in 38 DEG C of summer temperature, 22 DEG C of wet-bulb temperature, relative humidity 23% by air inlet 10
Cooler, by temperature after the humidifying cooling of one-level sprayer unit 9 become 25 DEG C, 22 DEG C of wet bulb, relative humidity 77%,
Then the tube bank of one-level air cooling 7 is lowered the temperature, temperature become 34 DEG C, 24 DEG C of wet bulb, relative humidity 45%,
Subsequently by temperature after two grades of humidifying coolings of sprayer unit 9 become 27 DEG C, 24 DEG C of wet bulb, relative humidity
78%, then two grades of air coolings tube bank 5 is lowered the temperature, temperature become 36 DEG C, 26 DEG C of wet bulb, relative humidity
46%, followed by by temperature after the humidifying cooling of three-level sprayer unit 4 become 29 DEG C, it is 26 DEG C of wet bulb, relative
Humidity 79%, finally carries out cooling and is finally completed 45 DEG C of thermal mediums from thermal medium inlet to three-level air cooling tube bank 2
3 ends for restraining 2, two grades of air cooling tube bank 5, one-level air cooling tube banks 7 by three-level air cooling were cooled to 35 DEG C of cooling
Discharged eventually through cold medium outlet 8, air enthalpy one-level level increases, but the wet-bulb temperature of air does not have
Increase it is too many this just make spray humidification temperature reduce herein after air remain to close to wet-bulb temperature i.e. cooling capacity
It is still very high, so the occupation of land of air cooler can be farthest reduced using the mode of multistage humidification, and because
Air enters the air inlet resistance of air cooler and the dynamic pressure of blower fan air-out increased the quiet of blower fan without multistage repetition
Press and reduce total energy consumption.
It is described above to be merely exemplary for the purpose of the present invention, and nonrestrictive, ordinary skill people
Member understand, in the case where the spirit and scope that claim is limited are not departed from, can many modifications may be made,
Change is equivalent, but falls within protection scope of the present invention.
