Description
Technical Field
[0001] This invention relates to the field of circulating water technology, and in particular to a method for improving the emergency response capability of circulating water systems. Background Technology
[0002] Circulating water is commonly used in factories for cooling, which is then used to cool steam, products, or equipment. For example... Figure 1 As shown, in industrial applications, circulating hot water is introduced into cooling tower 2 through inlet pipe 1 for cooling. The circulating hot water flows in a counter-current manner with the fan to cool the circulating hot water to the process standard. The cooled water then enters the corresponding water tank 3 of cooling tower 2 for storage, and is finally transported to the factory for use through the outlet pipe corresponding to water tank 3.
[0003] Because circulating water systems in factories typically operate 24 hours a day, and due to cost considerations, backup circulating water tanks are rarely installed, the circulating water systems lack emergency response capabilities. When a cooling tower fan malfunctions, the water in its corresponding tank can rapidly heat up, exceeding process standards. This phenomenon is particularly pronounced in summer, disrupting normal factory production.
[0004] Therefore, a technical solution is needed to address the problem that, in a circulating water system, the water temperature in the pool exceeds the process standard and affects normal factory production when the cooling tower corresponding to the pool malfunctions. Summary of the Invention
[0005] The purpose of this invention is to provide a method to improve the emergency response capability of a circulating water system, addressing the technical problem that when the cooling tower corresponding to the water tank in a circulating water system malfunctions, the water temperature in the water tank exceeds the process standard, affecting the normal production of the factory.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A method for improving the emergency response capability of circulating water systems includes the following steps: S1: Set up a circulation line to connect several water pools, so that water can circulate between the water pools. S2: Set up a return line, which connects all water tanks to the inlet pipes respectively, and introduces the water in the water tanks into the cooling tower for secondary cooling through the return line and the inlet pipes.
[0007] This invention provides a method to improve the emergency response capability of a circulating water system. When a cooling tower corresponding to a certain water tank fails, the water temperature in that water tank rises. By setting up a circulation line to connect all water tanks, the water is mixed and circulated in all water tanks. Then, a return line connects the water tanks to the inlet pipe, allowing the mixed water to re-enter the cooling tower for secondary cooling. The water after secondary cooling enters the corresponding water tanks. Simultaneously, through the circulation between the water tanks, the water temperature in the failed water tank is reduced again, ultimately bringing the water temperature in all water tanks up to the process standard, thereby ensuring a normal cooling water supply to all water tanks.
[0008] In a preferred embodiment of the present invention, all water tanks are connected in series on the circulation line. This achieves connectivity between all water tanks and simplifies the structure of the circulation line, thereby simplifying its production and installation processes.
[0009] In a preferred embodiment of the present invention, a first valve is provided between adjacent water tanks, and the first valve is located on the circulation line. When the cooling tower is operating normally, the first valve can be closed, making each water tank independent and facilitating individualized water quality treatment for each tank. Simultaneously, it allows for easy determination of whether a cooling tower malfunctions by observing the water tank temperature after a malfunction occurs.
[0010] As a preferred embodiment of the present invention, a first booster pump is provided on the circulation line. This boosts the power of water circulation between multiple water tanks when a cooling tower malfunctions, enabling the water to flow and mix rapidly between the tanks. This accelerates cooling and facilitates secondary cooling of the mixed water, preventing localized overheating.
[0011] In a preferred embodiment of the present invention, the return line is provided with several branch pipes, which are used to connect to the water tank. One end of the return line is connected to the inlet pipe, and the other end is connected to the water tank through the branch pipe, thereby realizing the connection between the water tank and the inlet pipe, which facilitates the drawing out of the water tank for secondary cooling.
[0012] As a preferred embodiment of the present invention, each of the branch pipes is equipped with a second valve. This facilitates the control of water backflow, and during normal operation of the cooling tower, the second valve can be used to isolate the water tank from the inlet pipe.
[0013] As a preferred embodiment of the present invention, a second booster pump is provided on the return line. This increases the water pressure, ensuring that the water flowing out of the pool has sufficient capacity to return to the cooling tower, thereby facilitating secondary cooling of the water.
[0014] As a preferred embodiment of the present invention, it further includes several temperature sensors, each corresponding to a water tank, for monitoring the water temperature exiting the tank. Real-time monitoring of the water temperature within the tank via these temperature sensors facilitates rapid determination of the tank's temperature, enabling staff to take timely emergency measures.
[0015] As a preferred embodiment of the present invention, it further includes a controller, wherein the temperature sensor, the first booster pump, the second booster pump, the first valve, and the second valve are electrically connected to the controller. When the temperature sensor detects that the water temperature in the pool exceeds a threshold, it first controls the opening of the first booster pump and the first valve to circulate the water in each pool, and then opens the second booster pump and the second valve to allow the water in the pool to enter the cooling tower through the return line for secondary cooling, thereby realizing automatic control of the water field emergency response.
[0016] As a preferred embodiment of the present invention, an alarm is also included, which is electrically connected to the controller. When the temperature in the water tank exceeds a threshold, the temperature sensor transmits a signal to the controller, which then controls the alarm to issue an audible or visual alarm, facilitating timely detection of the fault and implementation of maintenance measures by staff.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention adds a circulation line and a return line. The circulation line circulates the water in the faulty water tank and the normal water tank, and the return line introduces the water in the water tank into the cooling tower for secondary cooling. The water temperature is reduced again by the circulation between the water tanks after secondary cooling, so that the water temperature in all water tanks reaches the process standard. This ensures the normal cooling water supply to all water tanks and provides time for the repair of cooling tower failures. 2. Secondary cooling makes full use of the normally operating cooling tower to cool the water a second time, making it easier for the water temperature to reach the process standard.

Detailed Implementation
[0019] The present invention will now be described in detail with reference to the accompanying drawings.
[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0021] Example 1 like Figure 2 As shown in the figure, this embodiment of a method for improving the emergency response capability of a circulating water system includes the following steps: S1: Set up a circulation line 4 to connect several water pools 3, so that water can circulate between the various water pools 3; S2: Set up a return line 5, which connects all water tanks 3 to the water inlet pipe 1 respectively, and introduces the water in the water tanks 3 into the cooling tower 2 for secondary cooling through the return line 5 and the water inlet pipe 1.
[0022] During the operation of the circulating water system, when a cooling tower 2 corresponding to a certain water tank 3 malfunctions, the water temperature in that water tank 3 rises. By setting up a circulation line to connect all water tanks 3, the water is mixed and circulated in all water tanks 3. Then, the water tank 3 is connected to the inlet pipe 1 through the return line 5, so that the mixed water can re-enter the cooling tower 2 through the inlet pipe 1 for secondary cooling. The water after secondary cooling enters the corresponding water tank 3. At the same time, under the circulation between the water tanks 3, the water temperature of the malfunctioning water tank 3 is reduced again. Finally, the water temperature in all water tanks 3 reaches the process standard, thereby ensuring the normal cooling water supply to all water tanks 3.
[0023] Specifically, all water tanks 3 are connected in series on the circulation line 4, which enables all water tanks 3 to be connected and makes the structure of the circulation line 4 simpler, simplifying the production and installation process of the circulation line 4. A first valve 41 is provided between adjacent water tanks 3. The first valve 41 is located on the circulation line 4. When the cooling tower 2 is working normally, the first valve 41 can be closed, so that each water tank 3 is independent of each other. This makes it easy to determine whether the corresponding cooling tower 2 has failed by judging the temperature of the corresponding water tank 3 after the cooling tower 2 fails. Furthermore, a first booster pump 42 is provided on the circulation line 4 to increase the power of water circulation between multiple water tanks 3, so that the water can be quickly circulated and mixed between multiple water tanks 3. On the one hand, it can accelerate the cooling, and on the other hand, it can facilitate the secondary cooling of the mixed water to avoid local water temperature being too high.
[0024] Specifically, the return line 5 is equipped with several branch pipes 51, which are used to connect to the water tank 3. One end of the return line 5 is connected to the water inlet pipe 1, and the other end is connected to the water tank 3 through the branch pipe 51, thereby realizing the connection between the water tank 3 and the water inlet pipe 1, which facilitates the drawing out of the water tank 3 for secondary cooling. Each branch pipe 51 is equipped with a second valve 52 to facilitate the control of water return. When the cooling tower 2 is working normally, the water tank 3 and the water inlet pipe 1 can be isolated by the second valve 52. The return line 5 is equipped with a second booster pump 53 to increase the water pressure, so that the water flowing out of the water tank 3 has sufficient capacity to return to the cooling tower 2, thereby facilitating the secondary cooling of the water.
[0025] Example 2 like Figure 2 and Figure 3 As shown, the difference between this embodiment and embodiment 1 is that it also includes several temperature sensors 6. The temperature sensors 6 are digital display thermometers with waterproof probes, model: WST / DTM-491-CSF. The temperature sensors 6 are set one-to-one with the water tank 3. The temperature sensors 6 are set on the branch pipe 51 and are used to monitor the water temperature at the outlet of the water tank 3. The temperature sensors 6 monitor the water temperature in the water tank 3 in real time, which facilitates the rapid determination of the water temperature in the water tank 3 and allows the staff to take timely emergency measures.
[0026] Furthermore, it also includes a controller 7, which is a PLC controller, preferably an S7-200PLC. The temperature sensor 6, the first booster pump 42, the second booster pump 53, the first valve 41, and the second valve 52 are electrically connected to the controller 7. When the temperature sensor 6 detects that the water temperature in the water tank 3 exceeds the threshold, it first controls the first booster pump 42 and the first valve 41 to open, allowing the water to circulate in each water tank 3. Then, it opens the second booster pump 53 and the second valve 52, allowing the water in the water tank 3 to enter the cooling tower 2 through the return line 5 for secondary cooling, thus realizing automatic control of the emergency response of the circulating water field.
[0027] Furthermore, it also includes an alarm 8, preferably model TGSG-01. The alarm 8 is electrically connected to the controller 7. When the temperature in the water tank 3 exceeds the threshold, the temperature sensor 6 transmits a signal to the controller 7. The controller 7 controls the alarm 8 to emit an audible or visual alarm, so that staff can promptly detect the fault and take maintenance measures.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
