DETAILED DESCRIPTION

[0042] An embodiment of the present invention provides an evaporative condenser unit for accurately detecting the loss state of an anode replacement device in the evaporative condenser unit to avoid loss of a condenser in the evaporative condenser unit.

[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0044] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0045] As is known to all, when the evaporative condenser unit is set in different environments (pressure and temperature), the pressure of the environment around the evaporative condenser unit is different. For example, as the altitude increases, the pressure in the environment gradually decreases, and as the temperature increases, the pressure at the same altitude also gradually increases. Therefore, in order to accurately detect the wear state of the anode replacement device in the evaporative condenser unit and replace or supplement the anode replacement device in time, the environmental reference quantity is also one of the influencing factors that cannot be ignored. The evaporative condenser unit in this application is described in detail below in combination with the environmental quantity, so as to achieve accurate detection of the wear state of the anode replacement device in the evaporative condenser unit. The following is a detailed description:

[0046] See also Figure 1 The evaporative condenser unit includes a condenser 1, a spray device 2, an anode replacement device 3, a first pressure detection component 4, a second pressure detection component 5 and a spray liquid collecting tank 6.

[0047] A heat exchange cavity is formed inside the condenser 1 for circulating high-temperature fluid. When the high-temperature fluid passes through the condenser cavity, it conducts heat with the cavity wall of the condenser 1, so that the heat can be transferred to the outside of the condenser 1 through the cavity wall of the condenser 1, and then the heat can be absorbed by objects outside the condenser 1, such as air, thereby achieving a heat dissipation effect.

[0048] The spray device 2 is used to spray spray liquid to the condenser 1. When the spray liquid contacts the outer wall of the condenser 1 or the air near the outer wall, it absorbs heat and evaporates, thereby rapidly cooling the outer wall of the condenser 1 and the air near the outer wall. The spray liquid is generally water, but it can also be other liquids that are easy to evaporate and absorb heat. In order to avoid wasting the spray liquid, a spray liquid collection tank 6 is generally provided below the spray device and the condenser to collect the spray liquid that has not undergone a phase change after contacting the outer wall of the condenser 1 or the air near the outer wall.

[0049] The reducing property of the material of the anode replacement device 3 is higher than that of the material of the part of the condenser 1 in contact with the liquid, so that the anode replacement device 3 can react with the cathode ions in the spray liquid more easily than the condenser 1. Because the anode replacement device 3 can contact the spray liquid sprayed by the spray device 2 and / or the spray liquid to be sprayed, so that the cathode ions in the spray liquid sprayed by the spray device 2 and / or the spray liquid to be sprayed can react with the anode replacement device 3 more directly, thereby reducing the reaction between the cathode ions in the spray liquid and the exposed materials of the condenser 1, so as to avoid the loss of the condenser.

[0050] It should be noted that the anode replacement device 3 can be a powder type anode replacement device, or a block type, rod type, mesh type, plate type, etc. anode replacement device 3. The specific anode replacement device 3 is a magnesium piece. Mg (magnesium) is more likely to react with cathode ions in the spray liquid than metals such as Al (aluminum), Cu (copper), and Fe (iron); the material of the anode replacement device can be specifically selected according to the material of the condenser, so as to meet the reduction property of the anode replacement device 3 material higher than the reduction property of the material of the condenser 1 in contact with the liquid.

[0051] In addition, it should be noted that the anode replacement device 3 only needs to be in contact with the spray liquid sprayed by the spray device, and the position of the anode replacement device 3 in the evaporative condenser unit is not specifically limited here.

[0052] Furthermore, in order to obtain the wear status of the anode replacement device 3 in the evaporative condenser unit, the present application also provides a first pressure detection component 4 and a second pressure detection component 5 in the evaporative condenser unit for detecting the wear status of the anode replacement device 3, wherein at least one of the first pressure detection component 4 and the second pressure detection component 5 is arranged in a closed pressure chamber 7 built into the anode replacement device 3, and an initial pressure difference is set between the first pressure detection component 4 and the second pressure detection component 5, and the initial pressure difference changes with the damage of the closed pressure chamber 7, so as to obtain the wear status of the anode replacement device 3 in time when the evaporative condenser unit is located in different environments (different pressure environments and different temperature environments), so as to prevent damage to the condenser when the anode replacement device 3 is completely worn out.

[0053] During use of the evaporative condenser unit, spray liquid is circulated through the spray device 2. Since the anode replacement device 3 can contact the spray liquid, and the reducing property of the material of the anode replacement device 3 is stronger than that of the exposed material of the condenser 1, the anode replacement device 3 can react with the cathode ions in the spray liquid preferentially compared with the condenser 1, thereby effectively extending the service life of the condenser 1.

[0054] In order to more accurately monitor the wear state of the anode replacement device 3 in different environments and to better protect the condenser 1, the present application arranges a first pressure detection component 4 and a second pressure detection component 5 in the anode replacement device 3, and an initial pressure difference is arranged between the first pressure detection component 4 and the second pressure detection component 5, wherein the initial pressure difference is used to characterize the current environmental quantity, and the initial pressure difference changes with the damage of the closed pressure chamber, so that the wear state of the anode replacement device 3 can be timely acquired through the initial pressure difference.

[0055] As a specific embodiment, the working principle of the first pressure detection component 4 and the second pressure detection component 5 provided in the anode replacement device 3 is described below. Figure 2 :

[0056] Specifically, the first pressure detecting component 4 may be arranged in the closed pressure chamber 7 built into the last worn position of the anode replacement device 3 to detect the pressure in the closed pressure chamber, and the second pressure detecting component 5 may be arranged on the outer surface of the last worn position of the anode replacement device 3 to detect the ambient pressure. In this way, as the ambient quantity changes, the external pressure value detected by the second pressure detecting component 5 is different, so that the initial pressure difference changes with the change of the ambient quantity. Specifically, the ambient quantity includes at least one of the temperature environment and the pressure environment in which the evaporative condenser unit is located.

[0057] For example, when the evaporative condenser unit is at an altitude of 100 meters, assuming that the ambient pressure detected by the second pressure detection component is P1, and the pressure detected by the first pressure detection component is P2, the initial pressure difference is P2-P1; and when the evaporative condenser unit is at an altitude of 5000 meters, assuming that the ambient pressure detected by the second pressure detection component is P3, and the pressure detected by the first pressure detection component is P2, the initial pressure difference is P2-P3. It is obvious that P1 is greater than P3, so (P2-P1) is less than (P2-P3), that is, the initial pressure difference in the present application changes with the change of environmental quantities, so that the evaporative condenser unit can accurately detect the wear status of the anode replacement device 3 under different environments.

[0058] As the anode replacement device 3 is worn out, if the closed pressure chamber 7 is damaged, the initial pressure difference between the first pressure detection component 4 and the second pressure detection component 5 changes from the pressure difference between the pressure in the original closed pressure chamber 7 and the external environment to the pressure difference between the external environment and the external environment, that is, the initial pressure difference eventually becomes zero.

[0059] In addition, when the detection sensitivity of the first pressure detection component 4 and the second pressure detection component 5 is low, a first substance can be filled in the closed pressure chamber 7. When the closed pressure chamber 7 is damaged, the first substance can react quickly with the spray liquid and / or preset gas to cause a sudden change in the surrounding pressure and / or temperature, thereby causing an instantaneous sudden change in the initial pressure difference, so as to facilitate the pressure detection component to detect the pressure.

[0060] It should be noted that the position where the anode replacement device 3 is finally worn out changes according to the different positions where the anode replacement device 3 is set in the evaporative condenser unit, which will be specifically described in the following embodiments and will not be repeated here.

[0061] As another specific embodiment, the working principle of the first pressure detection component 4 and the second pressure detection component 5 provided in the anode replacement device 3 is described below. Figure 3 :

[0062] Specifically, in order to prevent the pressures detected by the first pressure detecting component 4 and the second pressure detecting component 5 from changing with changes in the external environment, the first pressure detecting component 4 can be arranged in the first closed pressure chamber 8 built into the last worn position of the anode replacement device 3, and the second pressure detecting component 5 can be arranged in the second closed pressure chamber 9 built into the last worn position of the anode replacement device 3, and an initial pressure difference is set between the first closed pressure chamber 8 and the second closed pressure chamber 9. In this way, because the first pressure detecting component 4 and the second pressure detecting component 5 are respectively arranged in their respective closed pressure chambers, the pressures detected by the first pressure detecting component 4 and the second pressure detecting component 5 will not change with changes in environmental quantities, wherein the environmental quantities include at least one of the temperature environment and pressure environment in which the evaporative condenser unit is located.

[0063] As the anode replacement device 3 is worn out, if either the first closed pressure chamber 8 or the second closed pressure chamber 9 is worn out first, the initial pressure difference between the first pressure detection component 4 and the second pressure detection component 5 becomes the first pressure difference between the pressure inside the first closed pressure chamber 8 and the ambient pressure, or becomes the second pressure difference between the pressure inside the second closed pressure chamber 9 and the ambient pressure.

[0064] If the first sealed pressure chamber 8 and the second sealed pressure chamber 9 are consumed at the same time, the initial pressure difference between the first pressure detection component 4 and the second pressure detection component 5 will become the pressure difference between the ambient pressure and the ambient pressure, that is, zero, thereby realizing the monitoring of the consumption status of the anode replacement device 3 by changing the initial pressure difference.

[0065] Furthermore, in the case where the detection sensitivity of the first pressure detecting component 4 and the second pressure detecting component 5 is low, at least one of the first closed pressure chamber 8 and the second closed pressure chamber 9 can be filled with a first substance, which can react quickly with the spray liquid and / or preset gas to cause a sudden change in the surrounding pressure and / or temperature.

[0066] If either the first sealed pressure chamber 8 or the second sealed pressure chamber 9 is worn out first, the initial pressure difference between the first pressure sensing component 4 and the second pressure sensing component 5 will undergo a sudden change due to the rapid reaction of the first substance, thereby achieving timely monitoring of the wear status of the anode replacement device 3 when the anode replacement device 3 is worn out.

[0067] If the first closed pressure chamber 8 and the second closed pressure chamber 9 are worn out at the same time, the initial pressure difference between the first pressure detection component 4 and the second pressure detection component 5 may change suddenly due to the asynchronous reaction of the first substance in the first closed pressure chamber 8 and the second closed pressure chamber 9, thereby realizing timely monitoring of the wear status of the anode replacement device 3 when the anode replacement device 3 is worn out.

[0068] based on Figure 2 In the embodiment described above, the position where the anode replacement device 3 is finally worn out is described in detail below. Figures 4A-4D :

[0069] As a specific embodiment, the anode replacement device 3 may be arranged at any position in the spray channel between the spray device 2 and the spray liquid collecting tank 6, such as arranging part of the anode replacement device 3 in the high temperature area of ​​the condenser 1, and arranging part of the anode replacement device 3 in the low temperature area of ​​the condenser 1, thereby solving the problem that the high temperature area of ​​the condenser 1 is easily damaged. Figure 4A shown.

[0070] Alternatively, the anode replacement device 3 is arranged at a fixed preset position in the spray liquid of the spray liquid collecting tank 6, that is, the anode replacement device 3 is completely immersed in the spray liquid of the spray liquid collecting tank 6, wherein the liquid level in the spray liquid collecting tank 6 is constant. In this way, the contact surface between the anode replacement device 3 and the spray liquid can be increased, thereby giving priority to ensuring the reaction between the anode replacement device 3 and the cathode ions in the spray liquid, so as to better protect the condenser 1 in the evaporative condenser unit, such as Figure 4B shown.

[0071] Alternatively, the anode replacement device 3 may be half-immersed in the spray liquid of the spray liquid collecting tank 6. Compared with the method of completely immersing the anode replacement device 3 in the spray liquid of the spray liquid collecting tank 6, this shortens the vertical distance between the anode replacement device 3 and the spray liquid sprayed by the spray device, thereby accelerating the reaction between the anode replacement device 3 and the cathode ions in the spray liquid sprayed by the spray device, and better protecting the condenser 1 in the evaporative condenser unit, such as Figure 4C shown.

[0072] Specifically, if the anode replacement device 3 is completely immersed in the spray liquid in the spray liquid collection tank 6, that is, the anode replacement device 3 is in complete contact with the spray liquid, because the probability of each surface of the anode replacement device 3 contacting the cathode ions in the spray liquid is exactly the same, the last consumed position of the anode replacement device 3 is the relative geometric center of the anode replacement device.

[0073] It is easy to understand that when the shape of the anode replacement device 3 is a regular shape, the relative geometric center of the anode replacement device 3 is the center point of the anode replacement device 3. When the shape of the anode replacement device 3 is an irregular shape, the multi-point suspension method can be used to determine the relative geometric center of the anode replacement device 3.

[0074] If the anode replacement device 3 is half immersed in the spray liquid in the spray liquid collecting tank 6, that is, the anode replacement device 3 is not completely in contact with the spray liquid, the last worn position of the anode replacement device 3 is the end of the anode replacement device 3 away from the part in contact with the spray liquid.

[0075] If the anode replacement device 3 is set in different temperature ranges, the higher the temperature, the faster the reaction rate between the anode replacement device 3 and the cathode ions in the spray liquid. Therefore, the last location where the anode replacement device 3 is worn out is the low temperature area in the anode replacement device 3.

[0076] Furthermore, in order to make the anode replacement device 3 wear out in the direction expected by the user, part of the surface of the anode replacement device 3 can be further treated with oxidation resistance or insulation to obtain an oxide layer or insulation layer 10, so that the anode replacement device 3 can be worn out first at the position that is not oxidized or not insulated, and then at the position that has been treated with oxidation resistance or insulation, as expected by the user. Figure 4D shown.

[0077] It is easy to understand that if part of the surface of the anode replacement device 3 is treated with oxidation resistance or insulation, the last position in the anode replacement device 3 to be worn is the position that has been treated with oxidation resistance or insulation.

[0078] In the embodiment of the present application, a detailed description is given of the position where the anode replacement device 3 is last worn out when the anode replacement device 3 is arranged at different positions in the evaporative condenser unit, thereby improving the accuracy of monitoring the wear status of the anode replacement device 3 .

[0079] Based on the above embodiments, the spray liquid is generally recycled, so the general evaporative condenser unit also includes a conveying device for pumping the liquid in the spray liquid collection tank 6 to the spray device 2. In addition, the evaporative condenser unit mainly uses the phase change heat of the external liquid to transfer the heat in the system to the outside, and generally includes a shell, a water retainer, etc.; and the condenser 1 forms a loop for transferring the heat in the system to the outside, and the loop is not limited to only pipeline heat exchange, or tube-fin heat exchange, plate heat exchange; the spray device 2 includes a liquid drive device, a liquid inlet, a liquid flow channel, a liquid outlet, etc.

[0080] Based on the evaporative condenser unit described in the above embodiment, a processor 11 electrically connected to the first detection component 4 and the second detection component 5 respectively can be provided in the evaporative condenser unit. Figure 5 , the following describes the process of replenishing or replacing the anode replacement device from the perspective of the processor 11:

[0081] The processor is used to:

[0082] Acquire a current environmental quantity, wherein the current environmental quantity includes at least one of a temperature environment and a pressure environment in which the evaporative condenser unit is located;

[0083] Acquire an initial pressure difference matching the current environmental quantity;

[0084] Acquire a threshold pressure difference, where the threshold pressure difference represents the pressure difference between the first pressure detection component 4 and the second pressure detection component 5 when the sealed pressure chamber of the anode replacement device is damaged;

[0085] If the initial pressure difference approaches the threshold pressure difference, an alarm message is sent to prompt the replacement or replenishment of the anode replacement device.

[0086] Because at least one of the first pressure sensing component 4 and the second pressure sensing component 5 in the embodiment of the present application is arranged in the closed pressure chamber 7 built into the anode replacement device 3, an initial pressure difference is set between the first pressure sensing component 4 and the second pressure sensing component 5, and the initial pressure difference changes with the damage of the closed pressure chamber 7, so that when the evaporative condenser unit is located in different environments (different pressure environments and different temperature environments), the wear status of the anode replacement device 3 can be obtained in time, and when the anode replacement device 3 is completely worn out (that is, when the initial pressure difference approaches the threshold pressure difference), the processor sends an alarm message in time to prompt the replacement or replenishment of the anode replacement device, thereby improving the convenience of obtaining the wear status of the anode replacement device.

[0087] Further, if the first pressure detection component 4 is arranged in the closed pressure chamber 7 built into the anode replacement device 3 to detect the pressure of the closed pressure chamber, and the second pressure detection component 5 is arranged on the outer surface of the anode replacement device 3, the initial pressure difference also changes with the change of environmental quantity.

[0088] Because the embodiment of the present application arranges the first pressure detection component 4 in the closed pressure chamber 7, and the second pressure detection component 5 in the anode replacement device 3, when the evaporative condenser unit is in different pressure environments and different temperature environments, the initial pressure difference will change with the change of the environment, thereby improving the accuracy of monitoring the wear status of the anode replacement device 3 under different environments.

[0089] Further, if the first pressure detection component 4 and the second pressure detection component 5 are respectively arranged in the first closed pressure chamber 8 and the second closed pressure chamber 9 built into the anode replacement device, the initial pressure difference does not change with the change of the environmental quantity.

[0090] In the embodiment of the present application, in order to avoid the influence of environmental quantities on the initial pressure difference, the first pressure detection component 4 and the second pressure detection component 5 can also be arranged in the first closed pressure chamber 8 and the second closed pressure chamber 9 at the same time, thereby avoiding the influence of environmental quantities on the initial pressure difference.

[0091] Furthermore, the sealed pressure chamber 7 is filled with a first substance, which can react quickly with the spray liquid and / or the preset gas to cause a sudden change in the surrounding pressure and / or temperature.

[0092] Furthermore, at least one of the first sealed pressure chamber 8 and the second sealed pressure chamber 9 is filled with a first substance, and the first substance can react quickly with the spray liquid and / or the preset gas to cause a sudden change in the surrounding pressure and / or temperature.

[0093] In order to further improve the accuracy of monitoring the threshold pressure difference, the first substance may be filled in the pressure chamber so that when the pressure chamber is damaged, the threshold pressure difference changes to a larger mutation value, thereby further improving the accuracy of monitoring the wear status of the anode replacement device 3.

[0094] Further, if the first sealed pressure chamber 8 and the second sealed pressure chamber 9 are not damaged at the same time, the threshold pressure difference is the first pressure difference between the second sealed pressure chamber 9 and the pressure corresponding to the current environmental quantity, or the second pressure difference between the first sealed pressure chamber 8 and the pressure corresponding to the current environmental quantity.

[0095] Furthermore, if the first sealed pressure chamber 8 and the second sealed pressure chamber 9 are damaged at the same time, the threshold pressure difference is zero.

[0096] Specifically, the working principles of the first pressure detection component 4 and the second pressure detection component 5 are as follows: Figures 1 to 4A -4D is similar to that described in the embodiment and will not be repeated here.
