Description

Technical Field

[0001] The utility model relates to the technical field of cooling systems, in particular to a circulating water cooling system. Background Art

[0002] Currently, circulating water cooling systems are widely used in various industries, including electronics, pharmaceuticals, chemicals, machinery manufacturing, and power generation. A circulating water cooling system uses water as a cooling medium and circulates it. After the cold water flows through the production equipment that needs to be cooled, its temperature rises. This warmed water is then passed through the cooling equipment to cool it down. The cooled water is then returned to the production equipment for reuse, saving significant amounts of industrial water. However, in circulating water cooling systems, the circulating water cooler is inefficient, energy- and environmentally unfriendly, and increases production operating costs. Utility Model Content

[0024] Reference Figure 1 , Figure 1A schematic diagram of a circulating water cooling system according to an embodiment of the present invention is shown. The circulating water cooling system provided by an embodiment of the present invention includes a heat exchanger 1, a rectifier 2, an unpowered cooling device 4, a water reservoir 3, and a filtration system. The water outlets of the heat exchanger 1 and the rectifier 2 are both connected to the water inlet of the unpowered cooling device via pipes. The water outlet of the unpowered cooling device is connected to the water reservoir 3. The water outlet of the water reservoir 3 is both connected to the water inlet of the heat exchanger 1 and the rectifier via pipes. The water reservoir 3 is also connected to the filtration system. The unpowered cooling device 4 includes a first unpowered cooling machine 4-1 and a second unpowered cooling machine 4-2. Water flowing out of the water outlets of the heat exchanger 1 and the rectifier 2 flows through the first unpowered cooling machine 4-1 and / or the second unpowered cooling machine 4-2 to the water reservoir 3. The provision of two unpowered cooling machines can improve the cooling effect. The first unpowered cooler 4-1 and the second unpowered cooler 4-2 both include a spiral casing, an impeller and a cooling fan. The impeller is arranged inside the spiral casing, and the impeller and the cooling fan are connected. The inlet water entering the first unpowered cooler 4-1 and / or the second unpowered cooler 4-2 drives the impeller in the spiral casing to rotate, and the rotating impeller drives the cooling fan to operate, thereby cooling the water in the water reservoir. A water outlet is provided below the first unpowered cooler 4-1 and the second unpowered cooler 4-2. The circulating water passes through the first unpowered cooler 4-1 and / or the second unpowered cooler 4-2 and is discharged below it. A filter screen is laid below the first unpowered cooler 4-1 and the second unpowered cooler 4-2, which has the function of filtering and increasing the heat dissipation of the water contact surface. The circulating water overflows into the water reservoir through the filter screen.

[0025] In one embodiment, further, it includes a dosing device 5, which is connected to the water reservoir 3 through a pipeline. Adding medicine into the water reservoir 3 can remove microorganisms in the water reservoir 3 to improve the water quality of the circulating water.

[0026] In one embodiment, further, the rectifying device 2 includes three rectifiers.

[0027] In one embodiment, the filtration system further includes a filtration device and a sand filtration device. The filtration device includes a first filter tank 6 and a second filter tank 7, and the sand filtration device includes a first sand filter tank 8 and a second sand filter tank 9. The circulating water in the water reservoir 2 first passes through the filtration device and then through the sand filtration device. The sand filtration device has a water outlet at the bottom thereof connected to the water reservoir 3.

[0028] In one embodiment, the filtration system further includes a buffer tank 10, which is arranged on one side of the sand filtration device. The buffer tank 10 is connected to the first decontaminated water tank 11 through a pipeline. A buffer pump 17 is provided on the pipeline between the buffer tank 10 and the first decontaminated water tank 11. The buffer pump 17 extracts the filtered impurities in the buffer tank 10 and sends them to the first decontaminated water tank 11.

[0029] In one embodiment, further comprising a standby cooling machine 12, the standby cooling machine 12 is arranged on one side of the unpowered cooling device. When the weather is hot (such as summer), the standby cooling machine 12 can be started to improve the cooling effect.

[0030] In one embodiment, the water reservoir 3 is further connected to the industrial water tank 13 through a pipeline, so that the water reservoir 3 can be replenished with water in time. A switch valve is set on the pipeline between the water reservoir 3 and the industrial water tank 13, and multiple circulating water pumps 14 are set on the outlet pipe of the water reservoir 3. The circulating water pumps 14 pump water from the water reservoir 3 into the filtration system, heat exchanger and rectifier.

[0031] In one embodiment, further, there are three circulating water pumps 14 .

[0032] In one embodiment, a thermometer 15 and a pressure gauge 16 are further provided on the water outlet pipe of the water reservoir 3 . The thermometer 15 can display the outlet water temperature of the water reservoir 3 , and the pressure gauge 16 can display the water pressure pumped out by the circulating water pump 14 .

[0033] In one embodiment, a drainage branch is further provided on the pipe from the water outlet of the heat exchanger 1 and the rectifier 2 to the water inlet of the unpowered cooling device for use in cleaning the pipe or relieving pressure during maintenance. The water discharged from the drainage branch is sent to the second sewage treatment tank 18.

[0034] The working mode of the circulating water cooling system is that the water outlets of multiple workstation heat exchangers 1 and rectifiers 2 are connected to the inlets of the first unpowered cooler 4-1 and / or the second unpowered cooler 4-2 (when the water flow is large, the two unpowered coolers are used at the same time, and when the water flow is small, only one unpowered cooler is used). The high-temperature water of the heat exchanger and the rectifier first passes through the first unpowered cooler 4-1 and / or the second unpowered cooler 4-2, and then flows from the outlet of the first unpowered cooler 4-1 and / or the second unpowered cooler 4-2 to the water reservoir 3 after being filtered. The cooling fans of the first unpowered cooler 4-1 and / or the second unpowered cooler 4-2 cool the water in the water reservoir. The water in the water reservoir 3 is filtered, sand filtered and drug-removed, and then connected to the water inlets of the heat exchangers 1 and rectifiers 2 of multiple workstations through pipes, thereby forming a circulating water cooling system.

[0035] The above-described embodiments merely represent several implementations of the present invention.
