Description
Technical Field
[0001] The embodiments of the present disclosure relate to the technical field of cooling towers, and in particular, to a novel low-temperature, water-saving closed cooling tower. Background Art

The main unit consists of a shell, a heat exchanger, a fan and other components, and is equipped with a water tank, a circulating water pump, an electric control cabinet, etc. The cooling medium is fully closed and circulated. When it is working, the cooling medium circulates between the heat exchanger and the equipment, and the spray water forms a water film outside the heat exchanger. The cold air and the spray water flow countercurrently through the heat exchanger, and the temperature is reduced by heat conduction and water evaporation. There are two modes of automatic switching: air cooling and air cooling + spraying. It has the advantages of preventing medium contamination and loss, reducing scaling failures, high cooling efficiency, easy installation, high degree of automation, and a wide range of applications. It is widely used in industry (cooling of equipment in chemical, electric power and other industries), commerce (air conditioning systems in large buildings), data centers (server cooling), medical (cooling of medical equipment) and other fields.
[0003] Currently, during the actual operation of closed cooling towers, cooling water needs to be continuously supplied to the circulation pipes to maintain the normal operation of the cooling system. During the cooling operation, due to heat exchange, a large amount of cooling water will evaporate into steam and dissipate into the air.

[0022] like Figures 1 to 6As shown, it shows a new type of low-temperature water-saving closed cooling tower in one embodiment of the present disclosure, including a cooling tower body 1, and also including: a discharge pipe 2, a guide pipe 4, a collection box 5, a refrigeration mechanism, a filtering mechanism and a discharge mechanism. The discharge pipe 2 is connected to the top of the cooling tower body 1, and a discharge fan 3 is installed in the discharge pipe 2. One end of the guide pipe 4 is connected to the top of the discharge pipe 2. The collection box 5 is fixedly connected to one end of the cooling tower body 1, and the other end of the guide pipe 4 is connected to the top of the collection box 5. The refrigeration mechanism is arranged at the top of the cooling tower body 1, and can filter the filter mechanism. 4 is cooled to cool and liquefy the water vapor. The filtering mechanism is arranged in the collecting box 5 and can filter impurities in the water flowing into the collecting box 5. The discharge mechanism is arranged on the collecting box 5 and can discharge water and gas separately. Through the cooperation among the discharge pipe 2, the guide pipe 4, the collecting box 5, the refrigeration mechanism, the filtering mechanism and the discharge mechanism, the hot steam at the discharge point of the cooling tower body 1 is cooled and liquefied, and the liquefied water is filtered and reused. A large amount of steam can be liquefied and recycled, which reduces the waste of water resources, reduces operating costs, and is more environmentally friendly.
[0023] The refrigeration mechanism includes: a temperature conducting frame 6, a semiconductor refrigeration plate 7, a controller 8 and a lifting assembly. The temperature conducting frame 6 is located at the top of the cooling tower body 1. A plurality of temperature conducting grooves are provided on the temperature conducting frame 6. The guide pipe 4 is coiled in the plurality of temperature conducting grooves. The semiconductor refrigeration plate 7 is fixedly connected to the bottom end of the temperature conducting frame 6. The cooling surface of the semiconductor refrigeration plate 7 contacts the bottom surface of the temperature conducting frame 6. The controller 8 is installed on one side of the cooling tower body 1. The controller 8 is connected to the semiconductor refrigeration plate 7. The lifting assembly is arranged on one side of the cooling tower body 1 and can support the temperature conducting frame 6 to fit with the guide pipe 4. The lifting assembly includes: a support plate 9 and a first electric cylinder 10. The support plate 9 is fixed Connected to one side of the cooling tower body 1, the temperature conducting frame 6 is slidably set on the support plate 9 through a sliding assembly. The first electric cylinder 10 is installed on one side of the cooling tower body 1. The output end of the first electric cylinder 10 is fixedly connected to the sliding assembly. The sliding assembly includes: a slide rod 11 and a drive frame 12. A sliding hole is opened on the support plate 9. The slide rod 11 is slidably connected in the sliding hole. There are two slide rods 11. Both slide rods 11 are fixedly connected to the bottom end of the temperature conducting frame 6. Both slide rods 11 are slidably connected to the support plate 9. The drive frame 12 is fixedly connected to the bottom ends of the two slide rods 11. The output end of the first electric cylinder 10 is fixedly connected to the bottom end of the drive frame 12.
[0024] The driving frame 12 is driven to rise by the first electric cylinder 10. When the driving frame 12 rises, it drives the slide bar 11 to slide upward on the support plate 9, thereby driving the temperature conducting frame 6 to fit with the guide pipe 4, and controlling the semiconductor refrigeration plate 7 to refrigerate through the controller 8. The temperature is transferred to the temperature conducting frame 6 through the semiconductor refrigeration plate 7, and the guide pipe 4 and the steam in the guide pipe 4 are cooled by the cooled temperature conducting frame 6, so that the steam is liquefied and flows into the collection box 5.
[0025] The filtering mechanism includes: a stabilizing plate 13, a transmission shaft 14, a filter mesh belt 15 and a first motor 16. The stabilizing plate 13 is fixedly connected to one side of the collecting box 5. There are two transmission shafts 14. Both transmission shafts 14 are rotatably connected to one side of the stabilizing plate 13. The two transmission shafts 14 are respectively located on both sides of the collecting box 5. Both sides of the collecting box 5 are provided with through grooves. The filter mesh belt 15 passes through the two through grooves and the filter mesh belt 15 is wound around the two transmission shafts 14. The first motor 16 is installed on the stabilizing plate 13. The output end of the first motor 16 passes through the stabilizing plate 13 and is fixedly connected to one of the transmission shafts 14.
[0026] When the liquefied water flows into the collection box 5, impurities in the water are filtered through the filter belt 15, and the filtered water is stored at the bottom of the collection box 5. After the filter belt 15 has been used for a long time, the first motor 16 installed on the stabilizing plate 13 drives the drive shaft 14 to rotate. Since the filter belt 15 is wound around two drive shafts 14, when one of the drive shafts 14 rotates, it can drive the filter belt 15 to move, thereby replacing the filtering position and improving the filtering efficiency.
[0027] The discharge mechanism includes: a return pipe 17, a drain pipe 18 and an exhaust assembly. The two ends of the return pipe 17 are respectively connected to the cooling tower body 1 and the collection box 5. The drain pipe 18 is connected to the bottom end of the collection box 5. Valves 19 are installed on the return pipe 17 and the drain pipe 18. The exhaust assembly is arranged at the top of the collection box 5 and can discharge the gas. The exhaust assembly includes: an exhaust box 20 and an exhaust fan 21. The exhaust box 20 is connected to the top of the collection box 5. The top of the exhaust box 20 is connected to the exhaust pipe 22. The exhaust fan 21 is installed in the exhaust box 20, and the output end of the exhaust fan 21 faces the exhaust pipe 22.
[0028] When the collected water needs to be transported into the cooling tower body 1 for use, the valve 19 on the return pipe 17 is opened to allow the water in the collection box 5 to be transported into the cooling tower body 1 through the return pipe 17. When the collected water needs to be discharged to the outside, the valve 19 on the drain pipe 18 is opened to allow the water stored in the collection box 5 to flow out, and the air is blown to the exhaust pipe 22 through the air outlet fan 21 installed in the exhaust box 20, thereby discharging the exhaust pipe 22 in the collection box 5 to the outside.
[0029] Working principle: when it is necessary to recycle steam water, first, the driving frame 12 is driven to rise by the first electric cylinder 10. When the driving frame 12 rises, it drives the slide bar 11 to slide upward on the support plate 9, thereby driving the temperature conducting frame 6 to fit with the guide pipe 4, and the semiconductor refrigeration plate 7 is controlled by the controller 8 to refrigerate, and the temperature is transferred to the temperature conducting frame 6 through the semiconductor refrigeration plate 7. Then the steam produced by the cooling tower body 1 enters the discharge pipe 2, and the steam is blown into the guide pipe 4 through the discharge fan 3. At this time, the guide pipe 4 has been cooled, and the steam in the guide pipe 4 and the guide pipe 4 is cooled by the cooled temperature conducting frame 6, so that the steam is liquefied and flows into the collection box 5. When the water flows into the collection box 5, the impurities in the water are filtered through the filter belt 15. The filtered water is stored at the bottom of the collection box 5. When the filter belt 15 passes through the filter belt 15, the steam is liquefied and flows into the collection box 5. After being used for a long time, the drive shaft 14 is driven to rotate by the first motor 16 installed on the stabilizing plate 13. Since the filter belt 15 is wound around the two drive shafts 14, when one of the drive shafts 14 rotates, the filter belt 15 can be driven to move, thereby replacing the filter position, thereby improving the filtration efficiency. The filtered water cup is stored inside the collection box 5. When the collected water needs to be transported into the cooling tower body 1 for use, the valve 19 on the return pipe 17 is opened to allow the water in the collection box 5 to be transported into the cooling tower body 1 through the return pipe 17. When the collected water needs to be discharged to the outside, the valve 19 on the drain pipe 18 is opened to allow the water stored in the collection box 5 to flow out. The air is blown to the exhaust pipe 22 through the air blower 21 installed in the exhaust box 20, thereby discharging the exhaust pipe 22 in the collection box 5 to the outside.
[0030] It should also be noted that the semiconductor cooling plate 7 and controller 8 are common existing devices on the market. Their operating principle is that the semiconductor cooling plate 7 operates based on the Peltier effect. When a DC current passes through a thermocouple consisting of an N-type and P-type semiconductor element, one end absorbs heat (the cold side) and the other end releases heat (the hot side). By switching the current direction, cooling or heating can be achieved. The cooling efficiency is related to the current and heat dissipation conditions. The accompanying controller 8 provides a stable DC voltage through a power driver module, uses PWM technology to adjust the current to control the cooling power, and uses a temperature sensor to collect real-time temperature. The PID algorithm automatically adjusts the output after comparing it with the set value, achieving precise temperature control.
[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and are not limiting. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, and all of these should be included in the scope of the claims of the present disclosure.
