Abstract

A cooling water recovery system includes an overflow device. The overflow device comprises an outer barrel suitable for containing cooling water and a condensation pipe located in the outer barrel, wherein the two opposite ends of the condensation pipe communicate with the water cooling pipe fitting and the interior of the outer barrel correspondingly. The inner face and the outer face of the outer barrel are communicated to form overflow holes.

When the liquid level of liquid cooling water which is contained in the outer barrel and comes from the condensation pipe is higher than the hole wall of the overflow hole, the liquid cooling water contained in the outer barrel can be guided outwards through the overflow hole, and therefore cooling water vapor can be discharged after being cooled, environmental pollution is reduced, excessive cooling water is recycled, and the service life of the cooling water is prolonged. And the cost is reduced.

Description

Technical Field

[0001] The invention relates to a cooling water recovery system, in particular to a cooling water recovery system applied to a water cooling device. Background Art

[0002] When the existing baking equipment needs to be cooled after the operation is completed, it can be cooled by air cooling or water cooling. Among them, water cooling is to bury the coil in the baking equipment, and let cooling water flow into the coil to absorb the heat energy in the baking equipment to achieve the cooling effect. In addition, in order to avoid the formation of scale when the cooling water flows in the coil and blocks the coil, the cooling water usually uses relatively expensive pure water or cold drainage. In addition, when the cooling water absorbs the heat energy in the baking equipment and is vaporized into water vapor, the volume of the cooling water vapor will expand 1700 times, making the air pressure in the coil too high, so it is necessary to release the pressure to prevent the coil from bursting. However, when the cooling water vapor is discharged to the outside, it will cause environmental thermal pollution. In addition, after the cooling water in the coil is discharged to the outside, new cooling water must be continuously added, which makes the cooling water consumption large, and then causes the cost of water cooling to be high. Summary of the invention

[0003] The object of the present invention is to provide a cooling water recovery system which can solve the above-mentioned problems.

[0004] The cooling water recovery system of the present invention is suitable for water-cooling pipes that can allow cooling water to pass through for heat exchange. The cooling water recovery system includes an overflow.

[0005] The overflow device comprises an outer cylinder body suitable for containing cooling water, and a condenser tube located in the outer cylinder body and having two opposite ends respectively connected to the water cooling pipe and the inner part of the outer cylinder body. The inner and outer surfaces of the outer cylinder body are penetrated to form an overflow hole.

[0006] The condenser is suitable for heat exchange between the cooling water vapor from the water-cooling pipe and the cooling water contained in the outer cylinder, so that the cooling water vapor from the water-cooling pipe condenses into liquid cooling water and is guided into the outer cylinder through the condenser. When the liquid level of the liquid cooling water from the condenser contained in the outer cylinder is higher than the hole wall of the overflow hole, the liquid cooling water contained in the outer cylinder can be guided outward through the overflow hole.

[0007] In the cooling water recovery system of the present invention, the condenser pipe extends downward from the top of the outer cylinder to the bottom of the outer cylinder, and has a port away from the water cooling pipe, and the port is spaced from the inner wall of the outer cylinder.

[0008] In the cooling water recovery system of the present invention, the two opposite ends of the water-cooling pipe fittings respectively form a water-cooling pipe water inlet and a water-cooling pipe water outlet. The condenser pipe is connected to the water-cooling pipe water outlet of the water-cooling pipe fittings. The cooling water recovery system also includes a water inlet pipeline, which includes a first pipe portion, a second pipe portion connected to the water inlet of the water-cooling pipe, a third pipe portion connected to the bottom of the outer cylinder, and a water inlet valve connected to the first pipe portion, the second pipe portion and the third pipe portion respectively. The water inlet valve can be controlled to divert the cooling water from the first pipe portion to at least one of the second pipe portion and the third pipe portion. The cooling water from the outside and passing through the first pipe portion and the water inlet valve can be diverted into the outer cylinder via the third pipe portion to reduce the temperature inside the outer cylinder.

[0009] In the cooling water recovery system described in the present invention, the two opposite ends of the water-cooling pipe fittings respectively form a water-cooling pipe water inlet and a water-cooling pipe water outlet. Among them, the condenser pipe is connected to the water-cooling pipe water outlet of the water-cooling pipe fittings. The cooling water recovery system also includes a water inlet pipeline. The water inlet pipeline includes a first pipe portion suitable for introducing cooling water from the outside, a second pipe portion whose two ends respectively connect the water inlet of the water-cooling pipe and the bottom of the outer cylinder, and a third pipe portion connected to the first pipe portion. The end of the third pipe portion away from the first pipe portion is connected to the bottom of the outer cylinder and is separated from the second pipe portion. The cooling water from the first pipe portion can be diverted to the outer cylinder of the overflow via the third pipe portion to reduce the temperature inside the outer cylinder. The cooling water from the bottom of the outer cylinder can be diverted to the water-cooling pipe fittings via the second pipe portion.

[0010] The cooling water recovery system of the present invention further comprises a temperature sensor which is installed in the outer cylinder and used to sense the temperature of the cooling water contained in the outer cylinder.

[0011] The beneficial effect of the present invention is that the cooling water vapor from the water-cooling pipe is exchanged with the cooling water contained in the outer cylinder through the condenser, so that the cooling water vapor from the water-cooling pipe can be discharged after cooling down, thereby reducing environmental pollution. Furthermore, the excess cooling water collected in the outer cylinder is diverted outward through the overflow hole, so that the cooling water can be diverted outward for recycling and reuse, thereby achieving the effect of reducing costs.

[0019] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0020] See also Figure 1 and Figure 2 , is an embodiment of the cooling water recovery system of the present invention. The cooling water recovery system is located outside a baking device 7, and is suitable for connecting a water-cooling pipe 8 installed in the baking device 7. The baking device 7 is provided with a box body, a heating device and other components not shown in the figure, and is used for heating. The water-cooling pipe 8 is, for example, a winding coil but not limited thereto, and can allow cooling water 9 to pass through for heat exchange. Specifically, the two opposite ends of the water-cooling pipe 8 respectively form a water-cooling pipe inlet 81 for the cooling water 9 to flow in, and a water-cooling pipe outlet 82 for the cooling water 9 to flow out. When the water-cooling pipe 8 guides the cooling water 9 through its interior, the cooling water 9 will absorb the heat energy in the baking device 7 through the pipe wall of the water-cooling pipe 8, and be vaporized into cooling water vapor 9', and the temperature in the baking device 7 is reduced. In this embodiment, the cooling water recovery system is installed on the outer surface of the baking device 7.

[0021] See also Figures 1 to 4, the cooling water recovery system comprises a water inlet pipeline 1, an overflow 2, a recovery pipeline 3 and a temperature sensor 4. The two ends of the water inlet pipeline 1 are respectively connected to the external cooling water source and the water cooling pipe water inlet 81 of the water cooling pipe 8, and are used to guide the external cooling water 9 to flow into the water cooling pipe water inlet 81. In this embodiment, the water inlet pipeline 1 includes a first pipe part 11, a second pipe part 12 connected to the water cooling pipe water inlet 81, a third pipe part 13 connected to the bottom of the overflow 2, and a water inlet valve 14 respectively connected to the first pipe part 11, the second pipe part 12 and the third pipe part 13. The water inlet valve 14 can be controlled (for example, manually controlled or electrically connected to a control module not shown in the figure) to guide the cooling water 9 from the first pipe part 11 to at least one of the second pipe part 12 and the third pipe part 13.

[0022] The overflow device 2 is cylindrical and includes an outer cylinder 21 suitable for containing cooling water 9, and a condenser 22 located inside the outer cylinder 21. The inner and outer surfaces of the outer cylinder 21 are penetrated to form an overflow hole 211. The bottom of the outer cylinder 21 is connected to the third pipe part 13. The two opposite ends of the condenser 22 are respectively connected to the water-cooling pipe outlet 82 of the water-cooling pipe 8 and the inside of the outer cylinder 21. The condenser 22 is suitable for providing cooling and heat exchange between the cooling water vapor 9' from the water-cooling pipe 8 and the cooling water 9 contained in the outer cylinder 21, so that the cooling water vapor 9' from the water-cooling pipe 8 is condensed into liquid cooling water 9 and is guided to the inside of the outer cylinder 21 by the condenser 22. Specifically, the condenser 22 includes a front pipe part 221 and a rear pipe part 222 that are connected to each other. One of the two opposite ends of the front tube portion 221 is connected to the baking device 7 and communicated with the water cooling pipe outlet 82, and the other of the two opposite ends of the front tube portion 221 is connected to the outside of the outer cylinder 21; the rear tube portion 222 is connected to the inside of the outer cylinder 21 and communicated with the front tube portion 221, and has a port 223 away from the water cooling pipe 8. The port 223 is communicated with the inside of the outer cylinder 21 and is spaced from the inner wall of the outer cylinder 21. In this embodiment, the rear tube portion 222 extends downward from the inner top of the outer cylinder 21 to the bottom of the outer cylinder 21, and is partially immersed in the cooling water 9 contained in the outer cylinder 21, and can perform heat exchange with the cooling water 9 contained in the outer cylinder 21. In addition, the overflow hole 211 is formed at the top of the outer cylinder 21, but is not limited thereto.

[0023] The recovery pipeline 3 is connected to the overflow hole 211 and an external recovery container (not shown), and is used for the cooling water 9 from the overflow hole 211 to circulate. Preferably, the recovery pipeline 3 is also connected to the water inlet pipeline 1 to guide the cooling water 9 from the overflow hole 211 to flow into the water inlet pipeline 1. The temperature sensor 4 is electrically connected to the control module (not shown). A part of the temperature sensor 4 is installed in the baking device 7, and another part of the temperature sensor 4 is inserted in the outer cylinder 21 and is used to sense the temperature of the cooling water 9 contained in the outer cylinder 21.

[0024] The operation of the cooling water recovery system is described in detail below. Figure 2 As shown, when the baking device 7 stops operating and needs to be cooled, the control module drives the water inlet valve 14 to a state of blocking the third pipe portion 13 and allowing the first pipe portion 11 and the second pipe portion 12 to communicate with each other, and the control module drives the external cooling water source to release the cooling water 9, so that the cooling water 9 is guided by the first pipe portion 11 and the second pipe portion 12 to flow into the water-cooling pipe 8. At this time, the cooling water 9 in the water-cooling pipe 8 absorbs the heat energy in the baking device 7 and is vaporized into cooling water vapor 9'. Then, the cooling water vapor 9' in the water-cooling pipe 8 will be guided by the water outlet 82 of the water cooling pipe to flow into the condenser 22, and then the cooling water 9 previously remaining in the front pipe portion 221 is pushed into the outer cylinder 21 through the rear pipe portion 222. In addition, the condenser 22 is used for heat exchange between the cooling water vapor 9' from the water-cooling pipe 8 and the cooling water 9 contained in the outer cylinder 21, so that the cooling water vapor 9' from the water-cooling pipe 8 is condensed into liquid cooling water 9 and guided into the outer cylinder 21 through the condenser 22. In this way, the cooling water vapor 9' can be cooled to avoid the problem of environmental thermal pollution.

[0025] Then, if Figure 3 As shown, when the liquid level of the liquid cooling water 9 from the condenser 22 contained in the outer cylinder 21 is higher than the hole wall of the overflow hole 211, the liquid cooling water 9 contained in the outer cylinder 21 can be diverted outward through the overflow hole 211 and flow into the recovery pipeline 3. In this way, the cooling water 9 can be collected in the external recovery container or returned to the water inlet pipeline 1 again to repeat the previous action of cooling the baking device 7.

[0026] Finally, if Figure 4As shown, when the temperature sensor 4 senses that the temperature of the cooling water 9 contained in the outer cylinder 21 exceeds the set value, the temperature sensor 4 notifies the control module, so that the control module drives the water inlet valve 14 to be in a state in which the first tube portion 11 is interconnected with the second tube portion 12 and the third tube portion 13 (or in a state in which the first tube portion 11 is only interconnected with the third tube portion 13), and the control module drives the external cooling water source to release the cooling water 9. In this way, the cooling water 9 from the outside or the recovery pipeline 3 and passing through the first tube portion 11 and the water inlet valve 14 can be diverted into the outer cylinder 21 through the third tube portion 13 to reduce the temperature of the cooling water 9 contained in the outer cylinder 21, while maintaining a good heat exchange efficiency with the condenser 22.

[0027] See also Figures 5 to 7 , is another implementation of this embodiment. In the above description, Figures 1 to 4 The water inlet pipeline 1 shown in the figure is an example including the first pipe part 11, the second pipe part 12, the third pipe part 13 and the water inlet valve 14. Figures 5 to 7 In the embodiment shown, the water inlet pipeline 1 only includes the first pipe part 11, the second pipe part 12 and the third pipe part 13. The first pipe part 11 is suitable for introducing cooling water 9 from the outside. The two ends of the second pipe part 12 are respectively connected to the water-cooling pipe water inlet 81 and the bottom of the outer cylinder 21 of the overflow 2. One end of the third pipe part 13 is connected to the first pipe part 11, and the other end of the third pipe part 13 is away from the first pipe part 11 and connected to the bottom of the outer cylinder 21 and is separated from the second pipe part 12. The cooling water 9 from the first pipe part 11 can be diverted to the outer cylinder 21 of the overflow 2 through the third pipe part 13 to reduce the temperature inside the outer cylinder 21. The cooling water 9 from the bottom of the outer cylinder 21 can be diverted to the water-cooling pipe 8 through the second pipe part 12. In this way, when the baking equipment 7 stops operating and needs to be cooled, the cooling water 9 from the outside can be guided to flow into the outer cylinder 21 through the first tube portion 11 and the third tube portion 13, and then, the cooling water 9 from the outer cylinder 21 can be guided to flow into the water-cooling pipe 8 through the second tube portion 12, so that the cooling water 9 from the outside can first cool down the subsequent cooling water vapor 9' from the condenser 22 before absorbing the heat energy of the baking equipment 7, and then be guided to flow into the water-cooling pipe 8 to cool the baking equipment 7. In this way, the cooling water recovery system can better recover the cooling water 9 during the initial operation.

[0028] In summary, the cooling water vapor 9' from the water-cooling pipe 8 is exchanged with the cooling water 9 contained in the outer cylinder 21 through the condenser 22, so that the cooling water vapor 9' from the water-cooling pipe 8 can be discharged after cooling down, so as to reduce environmental pollution. Furthermore, the excess cooling water 9 collected in the outer cylinder 21 is diverted outward through the overflow hole 211, so that the cooling water 9 can be diverted outward for recycling and reuse, so as to achieve the effect of reducing costs, so the purpose of the present invention can be achieved.
