While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
A first embodiment of the present invention provides a method of evaporative cooling, the method being applied to an evaporative cooling system. Therefore, to better understand the method, the evaporative cooling system will first be described.
As shown in fig. 1, the evaporative cooling system includes: a water supply regulating valve 101, a steam valve 104, a water pump 105, a heat exchanger 102, a deaerator 103 and a steam drum (the steam drum is not shown in the figure). As can be seen from fig. 1, the deaerator 103 is in communication with the heat exchanger 102, and specifically, the heat exchanger 102 includes: a first heat exchanger inlet 1021, a second heat exchanger inlet 1022, a first heat exchanger outlet 1023, and a second heat exchanger outlet 1024. The deaerator 103 includes: a first deaerator inlet 1031, a second deaerator inlet 1032, and a deaerator outlet 1033.
Wherein, the water supply governing valve 101 is connected with first heat exchanger import 1021, and first heat exchanger export 1023 is connected with first oxygen-eliminating device import 1031, and oxygen-eliminating device export 1033 is connected with second heat exchanger import 1022, and second heat exchanger export 1024 is connected with water pump 105, and steam valve 104 is connected with second oxygen-eliminating device import 1032, and the steam pocket is connected with steam valve 104.
The method of the present embodiment is illustrated in terms of a evaporative cooling system, as shown in FIG. 2, comprising:
s201, deoxidizing the to-be-deoxidized desalted water in the deaerator 103 to obtain deoxidized desalted water, wherein the to-be-deoxidized desalted water is transmitted to the deaerator 103 through the heat exchanger 102;
in the specific implementation process, the heat-exchanged heat-exchange desalted water is input into the deaerator 103 as new desalted water to be deaerated for deoxidation treatment through the first heat exchanger outlet 1023 and the first deaerator inlet 1031. The steam is then fed into the deaerator 103 through the steam valve 104 and the second deaerator inlet 1032. Finally, the desalted water to be deoxidized in the deaerator 103 is deoxidized through the action of the steam. Wherein the steam is stored in the steam drum, the steam in the steam drum is discharged into the deaerator 103 through the steam valve 104.
In step S201, the water to be deoxidized is heat-exchange water after being heated by the heat exchanger 102, and the water to be deoxidized is deoxidized by the deoxidation treatment, and the temperature of the water to be deoxidized is raised again in the deoxidation treatment. Therefore, in the deoxidation treatment of the desalted water to be deoxidized, the steam consumption is reduced, and the steam usage is saved.
Because in the deoxidation treatment, the filler layer is used for deoxidation, pressure deoxidation and boiling deoxidation, wherein the pressure deoxidation and the boiling deoxidation can consume steam, then the steam valve 104 and the inlet connected with the deaerator 103 through the steam valve 104 can be provided with the number according to the actual situation.
It should be noted that the nature of the deoxidized desalted water, heat exchange desalted water, etc. is desalted water, and since the desalted water is in different states, the naming mode is "state + desalted water".
S202, inputting the deoxidized desalted water and the heat exchange desalted water into the heat exchanger 102 for heat exchange to obtain cooled deoxidized desalted water and heat exchange desalted water after heat exchange, wherein the heat exchange desalted water is desalted water firstly input into the heat exchanger 102;
in a specific implementation, the heat exchange desalinated water is input into the heat exchanger 102 through the water supply regulating valve 101 and the first heat exchanger inlet 1021. The deoxygenated, desalinated water is then input into the heat exchanger 102 through the connection of the deoxygenator outlet 1033 and the second heat exchanger inlet 1022. And finally, carrying out heat exchange on the deoxidized desalted water and the heat exchange desalted water to obtain the deoxidized desalted water after cooling and the heat exchange desalted water after heat exchange. Wherein the heat exchange desalted water is desalted water at normal temperature.
In step S202, the heat-exchange desalted water at normal temperature is used as a heat-exchange medium to exchange heat with the deoxidized desalted water, so that the heat-exchange desalted water at normal temperature absorbs heat to raise the temperature, and the deoxidized desalted water releases heat to lower the temperature to form cooled deoxidized desalted water, thereby achieving the purpose of heat recycling between the deaerator 103 and the heat exchanger 102, reducing energy consumption, saving electric power, and also avoiding the need of adding other process flows or devices.
S203, taking the heat-exchanged desalted water as new desalted water to be deoxidized, and inputting the desalted water to the deaerator 103 for deoxidation treatment.
In the specific implementation process, the heat-exchanged desalted water after heat exchange is used as new desalted water to be deoxidized, and the new desalted water to be deoxidized is conveyed to the deoxidized desalted water through the outlet 1023 of the first heat exchanger and the inlet 1031 of the first deaerator.
After obtaining the cooled deoxygenated desalted water, the method further comprises:
the cooled deoxidized and desalted water is discharged by a water pump 105, wherein the water pump 105 is arranged on a pipeline of a second heat exchanger outlet 1024 of the heat exchanger 102.
The principle of the method of the embodiment is as follows: in the specific application, after deoxidation treatment is carried out on the deoxidized desalted water to be deoxidized in the deaerator 103 through steam, deoxidized desalted water is obtained, and the temperature of the deoxidized desalted water reaches 100 ℃. The deoxidized desalted water is transmitted to the deaerator 103 through the heat exchanger 102, namely the deoxidized desalted water is heat exchange desalted water after heat exchange. Because the temperature of deoxidized and desalted water is increased, deoxidized and desalted water is supplied to a steam pocket through a water pump 105 to be used by a cooling part, but the water pump 105 requires that the temperature of deoxidized and desalted water at an inlet of the deoxidized and desalted water is below 70 ℃, so that a procedure of reducing the temperature of deoxidized and desalted water is required to be added, and deoxidized and desalted water enters the water pump 105 after being cooled to below 70 ℃ through a heat exchanger 102.
Therefore, the deoxidized desalted water is input into the heat exchanger 102, meanwhile, the heat exchange desalted water is input into the heat exchanger 102, and then the deoxidized desalted water and the heat exchange desalted water are subjected to heat exchange to obtain the deoxidized desalted water after cooling and the heat exchange desalted water after heat exchange. Wherein the temperature of the heat exchange desalted water is normal temperature (10-25 ℃), the temperature of the deoxidized desalted water reaches 100 ℃, the temperature of the deoxidized desalted water after cooling reaches 70 ℃, and the temperature of the heat exchange desalted water after heat exchange reaches 50 ℃.
The heat-exchanged desalted water after heat exchange is used as new desalted water to be deoxidized and is input into the deaerator 103 for sampling treatment.
However, in the existing scheme, the heat exchange desalted water is directly input into the deaerator 103 (at this time, the temperature of the heat exchange desalted water is normal temperature), deoxidation treatment is performed, and the deoxidized heat exchange desalted water is obtained (at this time, the temperature of the deoxidized heat exchange desalted water reaches 100 ℃). Inputting deoxidized heat exchange desalted water into a heat exchanger 102, and simultaneously inputting clean circulating water into the heat exchanger 102 (at the moment, the temperature of the clean circulating water is normal temperature); and then, carrying out heat exchange on the deoxidized heat exchange desalted water and the purified circulating water to obtain cooled heat exchange desalted water and heat exchange purified circulating water, wherein the temperature of the cooled heat exchange desalted water reaches 70 ℃.
It should be noted that, since the heat exchange is performed by the clean circulating water, a part of the heat is taken away by the clean circulating water, and the temperature of the clean circulating water is increased. Therefore, a separate cooling tower is required to cool the clean circulating water, and the cooling tower further needs to use a water pump to recycle the clean circulating water.
Therefore, compared with the prior scheme, the method of the embodiment does not increase the clean circulating water for heat exchange, omits the process of the clean circulating water, reduces the using amount of the clean circulating water, and also eliminates the problem of pollution of the desalted water. Secondly, the temperature of the desalted water entering the deaerator 103 for deoxidation treatment is different, the method of the embodiment adopts the heat exchange desalted water after heat exchange as the desalted water to be deaerated, the temperature of the desalted water to be deaerated is higher than that of the desalted water at normal temperature, the steam consumption of the desalted water to be deaerated for deoxidation treatment is reduced, and the steam usage is saved. Finally, the method of the embodiment also adopts heat exchange desalted water and deoxidized desalted water for heat exchange, so that the problem of low-temperature heat recycling between the deaerator 103 and the heat exchanger 102 is directly solved, heat is left in the deaerator 103, power consumption is reduced, and the purpose of energy saving is achieved.
One or more technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:
in the embodiment, deoxidized water to be deoxidized in a deaerator is deoxidized to obtain deoxidized water, wherein the deoxidized water to be deoxidized is transmitted to the deaerator through a heat exchanger; inputting the deoxidized desalted water and the heat exchange desalted water into a heat exchanger for heat exchange to obtain cooled deoxidized desalted water and heat exchange desalted water after heat exchange, wherein the heat exchange desalted water is desalted water which is firstly input into the heat exchanger; and taking the heat-exchange desalted water subjected to heat exchange as new desalted water to be deoxidized, and inputting the desalted water into a deaerator for deoxidation treatment. Utilize heat transfer demineralized water under the normal atmospheric temperature as the heat transfer medium of deoxidation demineralized water, heat absorption intensification behind the heat transfer demineralized water heat exchange enters into the oxygen-eliminating device and carries out deoxidation treatment for the heat cyclic utilization between oxygen-eliminating device and cooler, thereby save steam consumption and power consumption. Therefore, the technical problem of how to reduce the energy consumption of the desalinized water deoxygenation process is solved.
