Abstract
Description
Technical Field
[0001] This application relates to the field of cooling fluid recovery technology, specifically providing a recovery device. Background Technology
[0002] In evaporative cooling power equipment, the cooling system is crucial for the stable operation of the equipment, with the performance of the coolant playing a key role. Over long-term operation, the coolant may undergo a series of physicochemical changes. For example, an increase in the water content of the coolant may lead to a decrease in its insulation performance; increased acidity may cause corrosion of equipment pipelines, and in severe cases, may even jeopardize system safety. Furthermore, the accumulation of impurities in the coolant may cause pipe blockage, thereby weakening the cooling effect. These changes directly affect the operating efficiency and safety of the entire cooling system.
[0003] Traditional methods for testing and purifying the cooling medium in related technologies typically involve the following steps: First, a cooling medium recovery device is installed at the exhaust end of the evaporative cooling system to collect the medium discharged from the system. After the system is shut down, samples of the cooling medium need to be manually extracted. These samples are then delivered to specialized testing personnel who conduct detailed analysis and testing in a laboratory using various equipment. Based on the test results, a corresponding purification plan is then developed. This testing and purification method is time-consuming, inefficient, and has high maintenance costs because it requires shutdown for each test and the samples need to be transported to the laboratory. It also affects the normal operation of the system.
[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0053] Evaporative cooling equipment uses a liquid cooling medium to absorb the heat generated by the equipment at the heat source. The medium then evaporates and turns into a gaseous state, achieving efficient cooling through heat exchange during the evaporation process.
[0054] refer to Figure 1 The recovery device provided in this application embodiment is connected to the exhaust end of the cooling equipment (not shown in the figure), and can recover the liquid or gas-liquid mixture of cooling working fluid discharged from the cooling equipment, thereby realizing the recycling of the working fluid.
[0055] Specifically, the recovery device includes a condenser 1. After the liquid or gas-liquid mixture of cooling fluid is discharged from the exhaust end, it is introduced into the condenser 1 for further cooling. The function of the condenser 1 is to completely condense the cooling fluid, transforming it completely from a gaseous or gas-liquid mixture into a liquid state, so as to facilitate subsequent purification and reuse.
[0056] Furthermore, the recovery device also includes a purification component and a collection container 5. The liquid cooling medium discharged from the condenser 1 is first purified by the purification component to ensure that its purity meets the requirements, and then it is transported to the collection container 5 for storage.
[0057] Specifically, the purification assembly includes a detection container 2 and a detection element disposed therein. One end of the detection container 2 is connected to the liquid inlet pipe 10 to receive liquid cooling medium from the condenser 1; the other end is connected to the liquid outlet pipe 30, through which qualified cooling medium is transported to the collection container 5.
[0058] Furthermore, the purification assembly also includes a processing module connected to the drain pipe 30. The detection element is used to detect the purity of the cooling medium discharged from the condenser 1, and the processing module purifies the cooling medium that does not meet the purity requirements according to the detection value of the detection element. After ensuring that its parameters meet the predetermined standards, it is then transported to the collection container 5 for storage for recycling.
[0059] The recycling device provided in this embodiment can not only recycle liquid cooling medium to avoid resource waste, but also perform real-time detection and purification of the discharged cooling medium through the coordinated work of detection elements and processing modules, ensuring that the cooling medium delivered to the collection container 5 fully meets the parameter requirements.
[0060] Specifically, compared with traditional methods, this device has significant technical advantages: First, its automation level is significantly improved, avoiding the cumbersome process of stopping the system first and then manually extracting samples and sending them to the laboratory for analysis, which improves operational efficiency and reduces errors caused by human intervention; Second, through its built-in real-time detection and processing program, this device can complete parameter monitoring and purification during the cooling medium discharge process. The real-time processing mechanism significantly shortens the processing cycle and improves processing efficiency and the compliance rate of cooling medium parameters.
[0061] Excessive impurities in the cooling medium can affect its heat exchange performance and, in severe cases, cause pipe blockage. Therefore, in one embodiment, the detection element includes a vision sensor 21. The vision sensor 21 determines the purity of the cooling medium by analyzing its color. For example, when the cooling medium remains clear and transparent or nearly clear and transparent, it indicates that the medium is relatively pure and has a low impurity content; conversely, if the cooling medium becomes turbid or darker in color, it indicates that there are more impurities in the medium, and purification treatment is required.
[0062] In one implementation, the vision sensor 21 is preferably a color sensor. The color sensor can accurately capture the color changes of the cooling medium and determine the purity of the medium by analyzing its spectral characteristics.
[0063] Furthermore, the response module corresponding to the vision sensor 21 in the processing module is a filtering module 41. The main function of the filtering module 41 is to remove impurities from the cooling working fluid to ensure its purity. Preferably, the filtering module 41 employs a two-stage filtration device, which includes a precision filter and an activated carbon filter.
[0064] The two-stage filtration system operates as follows: First, the cooling medium passes through a precision filter. This filter uses a precision filter element to intercept small particles and trace deposits in the medium. Its filtration accuracy is typically 1-10 microns, effectively removing solid impurities. Then, the cooling medium enters an activated carbon filter. The activated carbon removes oil contaminants, organic matter, and odors through adsorption, further purifying the cooling medium, especially removing trace amounts of oil from the liquid. This two-stage filtration mechanism significantly improves the purity of the cooling medium.
[0065] In one implementation, the filter module 41 is connected to the drain line 30 via a bypass branch. Specifically, the bypass branch includes a first branch line 301 and a second branch line 302. A first control valve 31 is connected in the drain line 30. The first branch line 301 and the second branch line 302 are respectively located on both sides of the first control valve 31. The two ends of the first branch line 301 are connected to the drain line 30 and the inlet of the filter module 41, respectively. The two ends of the second branch line 302 are connected to the drain line 30 and the outlet of the filter module 41, respectively.
[0066] Furthermore, a second control valve 32 is also connected to the first branch pipe 301. Both the second control valve 32 and the first control valve 31 are communicatively connected to the system controller. The controller determines whether the state of the cooling medium needs purification by monitoring and analyzing data from the vision sensor 21.
[0067] Specifically, when the vision sensor 21 detects a color change in the coolant exceeding a preset threshold, it indicates the presence of impurities or contaminants in the coolant. At this point, the controller will initiate a filtration program to purify the coolant according to a preset sequence.
[0068] When the filtration process is started, the controller closes the first control valve 31 and opens the second control valve 32, thereby guiding the cooling medium from the drain line 30 through the first branch line 301 into the filtration module 41. In the filtration module 41, the cooling medium undergoes thorough filtration and purification, and then returns to the drain line 30 through the second branch line 302.
[0069] Furthermore, a twelfth control valve 312 is also connected to the second branch pipe 302 to control the opening and closing of the second branch pipe 302. When the filtration process does not need to be started, the controller will control the first control valve 31 to open, while the second control valve 32 and the twelfth control valve 312 will close, thereby disconnecting the bypass branch where the filter module 41 is located and preventing the cooling working fluid from entering the filter module 41.
[0070] It should be noted that in this embodiment, opening the control valve means opening the valve to allow the cooling medium to pass through; closing the control valve means closing the valve to prevent the cooling medium from passing through.
[0071] In this embodiment, by incorporating a vision sensor 21 and a filter module 41 into the recycling device, the system can monitor the purity of the cooling fluid in real time and dynamically initiate the filtration process. This design effectively reduces the accumulation of impurities in the system, thereby avoiding problems such as pipe blockage and decreased cooling efficiency.
[0072] Since the moisture content in the cooling medium exceeds a certain threshold, it directly affects the insulation performance of the cooling medium. Therefore, in one embodiment, the detection element also includes a moisture sensor 22. The main function of the moisture sensor 22 is to monitor the moisture content in the cooling medium in real time.
[0073] Furthermore, the response module corresponding to the moisture sensor 22 in the processing module is a dehydration module 42. The dehydration module 42 can quickly and effectively remove excess moisture from the cooling medium through efficient centrifugal separation technology or other processing methods.
[0074] Similar to the filtration module 41, in one implementation, the dehydration module 42 is connected to the drain pipe 30 via a bypass branch to achieve purification and circulation of the cooling working fluid.
[0075] Specifically, the bypass branch also includes a third branch pipe 303 and a fourth branch pipe 304. A third control valve 33 is connected to the drain pipe 30, and the third branch pipe 303 and the fourth branch pipe 304 are located on both sides of the third control valve 33. One end of the third branch pipe 303 is connected to the drain pipe 30, and the other end is connected to the inlet of the dehydration module 42, while one end of the fourth branch pipe 304 is connected to the outlet of the dehydration module 42, and the other end is connected to the drain pipe 30.
[0076] Furthermore, a fourth control valve 34 is also connected to the third branch pipe 303. Both the fourth control valve 34 and the third control valve 33 are communicatively connected to the system controller. The controller determines whether the cooling medium needs purification by monitoring and analyzing data from the moisture sensor 22.
[0077] For example, when the moisture sensor 22 detects that the water content of the cooling medium exceeds a preset threshold, the controller will start a dehydration program to purify the cooling medium according to the preset program.
[0078] refer to Figure 1 The following explanation uses the dehydration process as an example. When only the dehydration process is started, the controller opens the first control valve 31, allowing the cooling medium to flow to the bypass branch where the dehydration module 42 is located. Simultaneously, it closes the second control valve 32 and the twelfth control valve 312 to prevent the cooling medium from entering the filter module 41. Further, it closes the third control valve 33 and opens the fourth control valve 34, guiding the cooling medium from the drain line 30 through the third branch line 303 into the dehydration module 42. In the dehydration module 42, the cooling medium undergoes thorough dehydration treatment and then returns to the drain line 30 through the fourth branch line 304.
[0079] Furthermore, a thirteenth control valve 313 is also connected to the fourth branch pipe 304 to control the opening and closing of the fourth branch pipe 304. When the dehydration program does not need to be started, the controller controls the third control valve 33 to open, and simultaneously controls the fourth control valve 34 and the thirteenth control valve 313 to close, so as to disconnect the bypass branch where the dehydration module 42 is located and prevent the cooling working fluid from entering the dehydration module 42.
[0080] By incorporating a moisture sensor 22 and a dehydration module 42 into the recovery unit, the system can monitor the water content of the cooling medium in real time and dynamically initiate the dehydration process. This design effectively reduces problems such as decreased electrical insulation performance and equipment corrosion caused by excessive moisture in the cooling medium.
[0081] If the pH value and hydrogen ion concentration in the cooling medium exceed a preset threshold, it will directly lead to corrosion of equipment pipelines and critical components, thereby affecting the normal operation of the system. In severe cases, this corrosion may cause equipment damage and endanger the safety of the entire system. Therefore, in one embodiment, the detection element also includes an acidity sensor 23. The main function of the acidity sensor 23 is to monitor the pH value in the cooling medium in real time.
[0082] Furthermore, the response module corresponding to the acidity sensor 23 in the processing module is the acid removal module 43. The acid removal module 43 can efficiently remove acidic components from the cooling working fluid through distillation separation technology.
[0083] In one implementation, the acid removal module 43 is connected to the drain line 30 via a bypass branch. Specifically, the bypass branch also includes a fifth branch line 305 and a sixth branch line 306. A fifth control valve 35 is connected to the drain line 30, and the fifth branch line 305 and the sixth branch line 306 are located on both sides of the fifth control valve 35. One end of the fifth branch line 305 is connected to the drain line 30, and the other end is connected to the inlet of the acid removal module 43, while one end of the sixth branch line 306 is connected to the outlet of the acid removal module 43, and the other end is connected to the drain line 30.
[0084] Furthermore, a sixth control valve 36 is also connected to the fifth branch pipe 305. Both the sixth control valve 36 and the fifth control valve 35 are communicatively connected to the system controller. The controller determines whether the cooling medium requires deacidification by monitoring and analyzing data from the acidity sensor 23.
[0085] For example, when the acidity sensor 23 detects that the water content of the cooling medium exceeds the preset threshold, the controller will start the acid removal program according to the preset program.
[0086] refer to Figure 1The following explanation uses the example of starting only the acid removal program. When only the acid removal program is started, the controller will open the first control valve 31 and the third control valve 33, while closing the bypass branch where the filter module 41 and the dehydration module 42 are located, so that the cooling working fluid flows to the bypass branch where the acid removal module 43 is located.
[0087] Furthermore, the controller closes the fifth control valve 35 and opens the sixth control valve 36, guiding the cooling medium from the drain pipe 30 through the fifth branch pipe 305 into the acid removal module 43. In the acid removal module 43, the cooling medium undergoes acid removal treatment and then returns to the drain pipe 30 through the sixth branch pipe 306.
[0088] Furthermore, a fourteenth control valve 314 is also connected to the sixth branch pipe 306 to control the opening and closing of the sixth branch pipe 306. When the acid removal program does not need to be started, the controller controls the fifth control valve 35 to open and simultaneously closes the sixth control valve 36 and the twelfth control valve 312, so as to disconnect the bypass branch where the acid removal module 43 is located and prevent the cooling working fluid from entering the acid removal module 43.
[0089] By incorporating an acidity sensor 23 and an acid removal module 43 into the recovery unit, the system can monitor the pH value of the cooling medium in real time and dynamically initiate the acid removal process. This design effectively prevents equipment corrosion and other problems caused by excessive acidic components.
[0090] Of course, the above embodiment is illustrated by activating a single processing module. In practical applications, multiple indicators such as the impurity content, water content, and acidity of the cooling medium may simultaneously exceed the threshold. In this case, the controller will determine which processing modules need to be activated for corresponding processing based on the feedback information from each sensor.
[0091] For example, if both impurities and moisture exceed the standard, the control system will sequentially activate the filtration module 41 and the dehydration module 42, allowing the cooling medium to enter the branch where the filtration module 41 and the dehydration module 42 are located for filtration and dehydration treatment.
[0092] This approach helps the recycling unit flexibly cope with various complex operating conditions. At the same time, by precisely controlling the start and stop of each processing module, energy can be effectively saved and the overall system operating efficiency improved.
[0093] In one embodiment, a liquid level sensor 24 is also provided in the detection container 2. The liquid level sensor 24 is used to monitor changes in the liquid level in the detection container 2 and feed them back to the controller. The controller will only start the corresponding processing program when the liquid level sensor 24 detects that the liquid level in the detection container 2 has reached a set value.
[0094] The advantage of this approach is that the controller can only begin processing when the coolant level reaches a sufficient capacity, avoiding energy waste and unnecessary equipment wear that could result from prematurely starting the process. Furthermore, the level sensor 24 effectively prevents excessive coolant in the detection container 2. If the level exceeds the maximum value set for the detection container 2, the controller will automatically close the seventeenth control valve 317 connected to the inlet pipe 10, stopping further inflow of coolant to prevent overflow due to excessive coolant in the detection container 2.
[0095] Furthermore, a ninth control valve 39 and a pump body 8 are connected in the drain line 30. Both of these components are connected to the controller and their working status is adjusted according to the detection value of the liquid level sensor 24.
[0096] Specifically, when the level sensor 24 detects that the liquid level in the detection container 2 has reached a preset value, the controller first closes the seventeenth control valve 317 in the inlet pipe 10 to prevent the liquid level from rising further. Then, by controlling the opening of the ninth control valve 39, the coolant in the detection container 2 is guided to the processing module. At the same time, depending on the specific needs of the processing module, the controller can also start the pump 8 to ensure that the coolant can smoothly and efficiently enter the processing module through the drain pipe 30.
[0097] In one embodiment, the processing module further includes a sampling module 44, which, like other processing modules, is connected to the drain line 30 via a bypass branch. The design of the sampling device enables the recovery device to periodically and automatically collect samples of the cooling medium and test its performance. This allows for the timely detection of potential problems in the cooling medium, such as excessive impurities or abnormal acidity.
[0098] Through this preventative detection method, the system can take corresponding measures before problems occur, such as activating the appropriate processing module to purify the cooling medium, thereby improving the overall stability and reliability of the cooling system.
[0099] Furthermore, a seventh control valve 37 is connected to the drain line 30. A seventh branch line 307 and an eighth branch line 308 are connected to both sides of the seventh control valve 37. The seven branch line 307 is connected at both ends to the drain line 30 and the inlet of the sampling module 44, respectively, while the eight branch line 308 is connected at both ends to the drain line 30 and the outlet of the sampling module 44, respectively. An eighth control valve 38 is also connected to the seventh branch line 307. Both the seventh control valve 37 and the eighth control valve 38 are communicatively connected to the controller.
[0100] When the system needs to start the sampling procedure, the controller will perform the following operations: First, the controller will close the seventh control valve 37 and open the eighth control valve 38, so that the cooling medium can flow from the drain pipe 30 through the seventh branch pipe 307 into the sampling module 44, thereby completing the sampling operation.
[0101] Furthermore, a fifteenth control valve 315 is also connected to the eighth branch pipe 308. When the sampling procedure is not required, the controller controls the seventh control valve 37 to open and controls the eighth control valve 38 and the fifteenth control valve 315 to close. In this way, it can be ensured that the cooling medium can flow along the normal path, thereby reducing unnecessary diversion and leakage.
[0102] Furthermore, a sixteenth control valve 316 is also connected to the section of the drain line located between the first return line 601 and the collection container 5. If the purified coolant meets the preset standard, the controller will open the sixteenth control valve 316 to guide the coolant into the collection container 5 for subsequent use. If the purified coolant fails to meet the preset standard, the system will continue the purification process to ensure that the coolant finally entering the collection container 5 fully meets the preset standard.
[0103] Furthermore, in the drain line, a flow meter 9 is also installed in the section of the pipeline between the first return line 601 and the collection container 5. The main function of the flow meter 9 is to monitor whether the liquid coolant in the pipeline is flowing normally. At the same time, through the data recorded by the flow meter 9, the system can obtain the specific flow rate of the coolant flowing through the drain line. In this way, the system can accurately calculate how much coolant has flowed through, thus providing data for subsequent operations and system optimization.
[0104] In one embodiment, a first return pipe 601 is also connected between the testing container 2 and the drain pipe 30. The main function of the first return pipe 601 is to enable the cooling working fluid to re-enter the testing container 2 for re-testing after purification by the processing module, so as to determine whether its performance parameters meet the requirements after purification.
[0105] Because the cooling medium is stored in the collection container 5 for a long time, its performance may change due to various factors, such as chemical reactions, temperature changes, or impurity accumulation. Therefore, in one embodiment, to ensure that the performance of the cooling medium in the collection container 5 is always in good condition, a second return line 602 is connected between the inlet of the collection container 5 and the detection container 2. The main function of the second return line 602 is to provide a path for the performance testing of the cooling medium in the collection container 5.
[0106] Furthermore, for ease of control, an eleventh control valve 311 is connected in the second return pipeline 602. When it is necessary to detect the cooling medium in the collection container 5, the controller controls the eleventh control valve 311 to open so that the cooling medium in the collection container 5 flows into the detection container 2. When it is not necessary to detect the cooling medium in the collection container 5, the controller controls the eleventh control valve 311 to close.
[0107] Furthermore, when the cooling equipment is shut down (e.g., during maintenance), if purification of the cooling medium in the unit is required, the controller will open the eleventh control valve 311, thereby introducing the cooling medium from the collection container 5 into the detection container 2. Subsequently, the system will purify these cooling media according to the control logic of each processing module in the previous embodiments. The specific purification process is similar to the process in the above embodiments, and therefore will not be described again here.
[0108] In one embodiment, in order to improve purification efficiency and purification effect, a first filter element 71 and a second filter element 72 are also provided in the drain pipe 30. These two filter elements are located at the inlet end and outlet end of the processing module, respectively.
[0109] Specifically, the first filter element 71 is located between the ninth control valve 39 and the pump body 8, and is used to perform preliminary filtration of the cooling medium discharged from the detection container 2. This step can effectively remove large particulate impurities and suspended solids from the cooling medium, ensuring that the medium entering the processing module is in a better initial state, thereby improving the working efficiency and service life of the processing module.
[0110] The second filter element 72 is located between the liquid outlet of the processing module and the first return pipe 601, and is used to further filter the cooling medium purified by the processing module. This filtration step can further remove tiny particles and residual impurities, ensuring that the cooling medium that finally enters the collection container 5 or re-enters the detection container 2 reaches a higher purity standard.
[0111] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
