Description

Technical Field

[0001] The utility model relates to the technical field of cooling water systems, and particularly relates to a multifunctional cooling water recycling device. Background Technique

[0002] Due to different temperature requirements of equipment and processes, in actual pipeline production, it is often necessary to cool down in some processes and heat up in some other processes. In the cooling operation, tap water is a commonly used cooling water because of its low water temperature, large supply volume, stability, etc. To save water and cost, the cooling water is usually set to be recycled. That is, when the cooling water passes through the cooling equipment, the material absorbs the cold quantity and is cooled down, and the cooling water absorbs the heat and is heated to hot water. The hot water is cooled down to cold water by a cooling fan (cooling tower) and then used for cooling again, thus forming a circulating system.

[0003] The existing devices have the following defects when in use:

[0004] 1. The content of impurities such as sediment in tap water is high. During the recycling process, the sediment will gradually deposit and is very difficult to discharge, resulting in the water quality becoming dirtier and affecting the cooling effect.

[0005] 2. The conductivity of the cooling water is not easy to measure or needs to be measured manually, resulting in untimely monitoring and untimely drainage.

[0006] 3. On the cooling equipment, usually one pump is used to cool one or more cooling devices. When the pump fails, the equipment can only be shut down due to the lack of cooling water, resulting in losses.

[0007] Therefore, how to provide a multifunctional cooling water recycling device has become a technical problem to be solved by those skilled in the art. Content of the Utility Model

[0008] The technical problem to be solved by the utility model is how to provide a multifunctional cooling water recycling device.

[0009] To achieve the above object, the utility model provides a multifunctional cooling water recycling device, including: a cooling tower, a cooling water tank is connected below the cooling tower through a pipeline, a cooling water pump is connected below the cooling water tank through a cooling water use channel, the water outlet end of the cooling water pump is connected to a cooling device through a pipeline, one end of the cooling device is provided with a cooling water circulation channel, the other end of the cooling water circulation channel is connected to the cooling tower, a partition is arranged inside the cooling water tank, the partition divides the inside of the cooling water tank into a primary chamber and a secondary chamber in parallel, and a filter screen is installed at the upper end of the partition.

[0010] The cooling water in the cooling tower enters the cooling water tank through a preset pipeline. The cooling water in the cooling water tank is pumped into the cooling equipment by a cooling water pump under the action of the cooling water use channel to cool the cooling equipment. The cooled cooling water in the cooling equipment flows back to the cooling tower through the cooling water circulation channel to achieve the purpose of recycling. The design of the filter screen on the partition allows water to pass through the filter screen, but impurities such as sediment cannot pass through the filter screen, so that the water flowing down from the cooling tower can only enter the first chamber. The sediment, impurities, etc. in the cooling water have a density greater than that of water, so they continuously sink to the bottom of the first chamber, while the high-level water enters the second chamber through the top filter screen, thereby filtering impurities such as sediment in the tap water.

[0011] Preferably, two of the cooling towers are arranged in parallel.

[0012] The cooling tower adopts the existing structure on the market in the field, which is used to cool and lower the temperature of the circulating water. This method is common knowledge in the field, so it will not be elaborated here.

[0013] Preferably, drain valves are installed at the bottoms of the first chamber and the second chamber of the cooling water tank, and the inner bottom end of the first chamber of the cooling water tank is inclined.

[0014] The bottom of the first chamber is inclined, which is more conducive to the precipitation and discharge of impurities such as sediment. Impurities such as sediment are deposited at the lowest place due to their large density. When there is more sediment deposited in the first chamber, the drain valve at the bottom of the first chamber can be opened to discharge the sediment. The primary drain valve is set to automatically open once a day, and the opening time is 10 minutes. The sediment and other impurities in the first chamber are discharged by the way of regular discharge every day. The drain valve at the bottom of the second chamber is used to discharge the high-concentration ionic water inside it.

[0015] Preferably, a liquid level gauge, a conductivity meter, and a thermometer are installed on one side of the second chamber of the cooling water tank.

[0016] The liquid level gauge, the conductivity meter, and the thermometer adopt the existing structures on the market. Among them, the liquid level gauge is used to monitor the liquid level of the cooling water in the second chamber in real time online, the conductivity meter monitors the ion content in the cooling water in the second chamber in real time online, and the thermometer is a temperature sensor that detects the temperature of the cooling water in the second chamber in real time.

[0017] Preferably, the cooling water use channel is an inlet buffer pipe. The inlet end of the inlet buffer pipe is connected to the second chamber of the cooling water tank through a pipeline, and the outlet end of the inlet buffer pipe is connected to the cooling water pump through a pipeline. A drain valve is installed at the bottom of the inlet buffer pipe.

[0018] The water buffer pipe mainly plays the role of buffering and distributing the cooling water, which can make the water inlet of the cooling water pump more stable. When there is more sediment deposited in the inlet buffer pipe, the sediment and other impurities can be discharged through the drain valve at its bottom.

[0019] Preferably, one or more sets of the cooling water pumps and the cooling devices are correspondingly provided, and three control valves are preset on the water outlet pipes of each set of the cooling water pumps and the cooling devices.

[0020] The cooling water pumps extract the cooling water in the inlet buffer pipe to cool the cooling devices. A connecting pipe and a connecting valve are further arranged behind multiple cooling water pumps. When one of the cooling water pumps is under maintenance, other pumps can be used to supply the cooling water by switching the valves to meet the requirements, forming a multi-pump connecting function.

[0021] Preferably, the cooling water circulation channel is a return water buffer pipe. The water inlet pipe of the return water buffer pipe is connected to the cooling device through a pipeline. The water outlet end of the return water buffer pipe is provided with a diversion pipe. Two diversion pipes are arranged in parallel, and the two diversion pipes are correspondingly connected to two cooling towers. Thermometers are installed on both of the two diversion pipes. A sewage discharge valve is installed at the bottom of the return water buffer pipe.

[0022] After the cooling water passes through the cooling device, the temperature of the material or the device decreases, and the temperature of the cooling water increases and becomes hot water. All the hot water is centrally recovered into the return water buffer pipe and flows back into the interior of the cooling tower through the diversion pipe. The design of the sewage discharge valve is used to discharge impurities such as sediment inside the return water buffer pipe.

[0023] Preferably, the cooling components are correspondingly installed on two cooling towers. The cooling components include corrugated sheets and fans. The corrugated sheets are installed on the top wall of the cooling tower and are arranged in parallel at equal intervals. The fans are installed on the top of the cooling tower.

[0024] The hot water flowing back into the interior of the cooling tower is shunted and cooled by the corrugated sheets and forms a rain curtain-like shape and falls into the tower. At the same time, the hot air is sucked out from the top of the cooling tower by the fan, thereby reducing the water temperature.

[0025] Preferably, the chemical dosing component includes a chemical dosing pump and a chemical dosing barrel. The feed end of the chemical dosing pump is connected to the chemical dosing barrel through a pipeline, and the discharge end of the chemical dosing pump is connected to the first chamber of the cooling water tank through a pipeline.

[0026] As the cooling water gradually circulates, the concentration multiple of the cooling water gradually increases, the ion concentration in the water becomes higher and higher, the conductivity increases, and it is extremely easy to generate impurities such as water scale, moss and other algae. The design of the chemical dosing component is used to remove impurities such as water scale inside the cooling water tank. Disinfectants, scale inhibitors and other chemicals are preset in the chemical dosing barrel according to the specified ratio.

[0027] Preferably, the cleaning component is a tap water pipeline. The water outlet end of the tap water pipeline is a shunt pipe structure and correspondingly extends into the interiors of two cooling towers and is located below the corrugated sheets.

[0028] With the recycling of the cooling water, impurities such as sediment and moss will gradually adhere to the surface of the corrugated sheet, and the cleaning component is designed to clean the corrugated sheet.

[0029] The beneficial effects of the present utility model are as follows:

[0030] 1. When the present utility model is in use, the bottom of the first-stage chamber of the cooling water tank is inclined, which is more conducive to the precipitation and discharge of impurities such as sediment. The design of the filter screen on the partition plate allows water to pass through the filter screen, but impurities such as sediment cannot pass through the filter screen. Therefore, the water flowing down from the cooling tower can only enter the first-stage chamber. The sediment, impurities, etc. in the cooling water have a density greater than that of water, so they continuously sink to the bottom of the first-stage chamber, while the high-level water enters the second-stage chamber through the top filter screen, filtering impurities such as sediment in the tap water, thus ensuring the water quality and improving the cooling effect.

[0031] 2. When the present utility model is in use, by setting a liquid level gauge, a thermometer, and a conductivity meter, real-time online detection of the cooling water is achieved. Through the cooperation of valve and fan control, automatic water replenishment, drainage, temperature control, and conductivity control are realized, reflecting the automation degree of this device.

[0032] 3. When the present utility model is in use, by setting a connecting valve and a connecting pipe, idle or multiple cooling water pumps can be connected for emergency use, avoiding losses caused by the lack of cooling water when the pump fails, reflecting the practicality of this device.

[0033] 4. When the present utility model is in use, a chemical dosing component is set to perform operations such as sterilization, algae removal, flocculation, and scale inhibition on the recycled cooling water, improving the quality of the cooling water. A cleaning component is also set to clean the impurities on the corrugated sheet, avoiding the influence of impurities on the water quality, thus further ensuring the water quality and improving the cooling effect, which is conducive to popularization and use.

There are two cooling towers 1 arranged in parallel. Drain valves are installed at the bottoms of the first chamber and the second chamber of the cooling water tank 2, and the bottom end of the first chamber of the cooling water tank 2 is arranged in an inclined shape. A liquid level gauge 5, a conductivity meter 6 and a thermometer 7 are installed in parallel on one side of the second chamber of the cooling water tank 2. The cooling water use channel is an inlet buffer pipe 8, the inlet end of the inlet buffer pipe 8 is connected to the second chamber of the cooling water tank 2 through a pipeline, the outlet end of the inlet buffer pipe 8 is connected to the cooling water pump 9 through a pipeline, and a drain valve is installed at the bottom of the inlet buffer pipe 8. There is one set or more of the cooling water pump 9 and the cooling device 10, and three control valves are preset on the outlet pipelines of each set of the cooling water pump 9 and the cooling device 10. The cooling water circulation channel is a return buffer pipe 11, the inlet pipe of the return buffer pipe 11 is connected to the cooling device 10 through a pipeline, the outlet end of the return buffer pipe 11 is provided with a diversion pipe 1101, there are two diversion pipes 1101 arranged in parallel, and the two diversion pipes 1101 are correspondingly connected to the two cooling towers 1, and thermometers 7 are installed on both of the two diversion pipes 1101. A drain valve is installed at the bottom of the return buffer pipe 11. Cooling components are correspondingly installed on the two cooling towers 1. The cooling components include corrugated sheets 12 and fans 13. The corrugated sheets 12 are installed on the top wall of the cooling tower 1 and are arranged in parallel at equal intervals. The fans 13 are installed on the top of the cooling tower 1. The chemical dosing component includes a chemical dosing pump 14 and a chemical dosing tank 15. The feeding end of the chemical dosing pump 14 is connected to the chemical dosing tank 15 through a pipeline, and the discharging end of the chemical dosing pump 14 is connected to the first chamber of the cooling water tank 2 through a pipeline. The cleaning component is a tap water pipeline 16, the water outlet end of the tap water pipeline 16 is a shunt pipe structure and correspondingly extends into the two cooling towers 1 and is located below the corrugated sheets 12;

[0042] In this embodiment:

[0043] First of all, the cooling water in the cooling tower 1 enters the inside of the cooling water tank 2 through a preset pipeline;

[0044] Secondly, when the cooling water enters the interior of the cooling water tank 2, the design of the filter screen 4 on the partition plate 3 allows water to pass through the filter screen 4, but impurities such as sediment cannot pass through the filter screen 4. As a result, the water flowing down from the cooling tower 1 can only enter the primary chamber. Sediment, impurities, etc. in the cooling water have a density greater than that of water, so they continuously sink to the bottom of the primary chamber, while the high-level water enters the secondary chamber through the top filter screen 4 to filter impurities such as sediment in the tap water, thus ensuring the water quality and improving the cooling effect. When the cooling water tank 2 is replenished with water, the liquid level gauge 5 monitors the water level in the secondary chamber in real time online. When the liquid level gauge 5 detects that the liquid level in the secondary chamber is lower than the set value, it sends a signal to open the tap water replenishing valve at the top of the primary chamber to replenish tap water into the primary chamber. After the primary chamber is full of water, it enters the secondary chamber. When the water level in the secondary chamber reaches the high-level setting, the tap water replenishing valve closes and the water replenishment stops. Moreover, the thermometer 7 outside the secondary chamber detects the water tank temperature in real time. When the water tank temperature is higher than the set value, it sends a signal to increase the rotation frequency of the fan 13 at the top of the cooling tower 1, so that the temperature of the cooling water flowing out of the cooling tower 1 drops, so that the temperature of the cooling water drops to the required value. When the water tank temperature is lower than the set value, it sends a signal to decrease the rotation frequency of the fan 13 at the top of the cooling tower 1, so that the temperature of the cooling water flowing out of the cooling tower 1 rises, so that the temperature of the cooling water rises to the required value;

[0045] Next, after the cooling water flows out of the secondary chamber, it flows into the inlet buffer pipe 8. At the same time, the cooling water pump 9 is started to pump the cooling water into the interior of the cooling equipment 10 to cool down the cooling equipment 10. When pumping in the cooling water, a connecting pipe and a connecting valve are also provided behind multiple cooling water pumps 9. When one of the cooling water pumps 9 is under maintenance, other pumps can be used to supply the cooling water by switching the valve to meet the demand, which reflects the practicability of this device. During the process of supplying cooling water, the conductivity meter 6 monitors the ion content in the cooling water in real time online. When the conductivity meter 6 detects that the conductivity of the cooling water is higher than the set value, it sends a signal to open the drain valve at the bottom of the secondary chamber to discharge the high-concentration ion water. As the high-concentration ion water is continuously discharged, the water tank liquid level drops. At this time, if the liquid level is lower than the set value, the replenishing valve opens and tap water is replenished into the water tank. The conductivity of the cooling water continuously drops to the set required value, the drain valve closes, and the water replenishment stops after the water level reaches the high limit, thus ensuring the cooling and temperature reduction effect;

[0046] Then, after the cooling water passes through the cooling device 10, the temperature of the material or the equipment decreases, and the temperature of the cooling water increases and becomes hot water. All the hot water is centrally recovered into the return water buffer pipe 11 and is divided into two paths through the diversion pipe 1101 to enter the corresponding cooling towers 1 respectively. Thermometers 7 are installed on both paths to monitor the return water temperature in real time. After the warm water enters the cooling tower 1, it is shunted and cooled through the corrugated sheets 12 laid on the top of the tower, forming a rain curtain-like shape and falling into the tower. At the same time, the fan 13 is started, and the hot air is sucked out from the top by the fan 13, thereby reducing the water temperature. After the temperature of the warm water drops, it enters the inside of the cooling water tank 2 for recycling;

[0047] Finally, during use, the dosing pump 14 is started regularly to pump the medicine in the dosing barrel 15 into the inside of the cooling water tank 2 to perform treatments such as sterilization, algae removal, flocculation, and scale inhibition on the cooling water, and to reduce the generation of impurities such as scale, microorganisms, and algae. When not in use, tap water can be added into the tap water pipe 16, so that the tap water sprays out from the dispersed capillary pores to clean the corrugated sheets 12, and the drain valves at the bottoms of the first-stage chamber, the water inlet buffer pipe 8, and the return water buffer pipe 11 can be opened regularly to discharge the impurities inside to the outside.

[0048] The above-disclosed is only a preferred embodiment of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
