Description

Technical Field

[0001] The present application relates to the field of cooling technology, and in particular to a cooling tower circulating cooling system. Background Art

[0002] Currently, photovoltaic glass kiln production lines have very stringent requirements for process circulating cooling water, requiring higher water quality and pressure stability than other production lines. This circulating water requires a refrigeration system to maintain temperature control. However, since the cooling towers in these refrigeration systems typically use tap water, a water outage can cause the cooling towers to stop operating or malfunction due to low water levels. This is particularly true in the northwest region, where water resources are scarce and water outages are common. These conditions can cause cooling tower failures, impacting the refrigeration system and, in turn, the temperature stability of the process circulating water.

[0003] Therefore, how to provide a stable cooling water circulation system becomes an urgent problem to be solved. Utility Model Content

[0008] The first electric valve is arranged at the first water outlet of the high-level water tank and is electrically connected to the first liquid level gauge. When the liquid level height sensed by the first liquid level gauge is lower than the first preset liquid level height, the first electric valve opens, and the coolant in the high-level water tank is transmitted to the cooling tower through the first water outlet and the first pipeline.

[0009] In some embodiments, it further includes:

[0013] The first water pump is arranged at the second water outlet of the production water pool, and is used to pump the liquid in the production water pool into the cooling tower through the second pipeline.

[0014] In some embodiments, it further includes:

[0015] A pressure sensing device is provided between the water supply device and the second pipe for sensing the pressure of the liquid provided by the water supply device. The pressure sensing device is also electrically connected to the first water pump so that when the pressure sensed by the pressure sensing device is lower than a preset pressure, the first water pump is turned on to pump the liquid in the production water pool into the cooling tower through the second pipeline and the third pipeline.

[0016] In some embodiments, it further includes:

[0017] The second electric valve is arranged at the third water outlet of the water supply device. The second electric valve is electrically connected to the pressure sensing device so that when the pressure sensed by the pressure sensing device is lower than the preset pressure, the second electric valve is closed; and when the pressure sensed by the pressure sensing device is greater than the preset pressure, the second electric valve is opened.

[0018] In some embodiments, it further includes:

[0019] The second liquid level gauge is arranged in the high-level water tank to sense the liquid level height of the high-level water tank. The second liquid level gauge is also connected to the first water pump so that the first water pump is turned on when the liquid level height sensed by the second liquid level gauge is lower than the second preset liquid level height.

[0020] In some embodiments, the second water outlet of the production water pool is further connected to the high-level water tank through a fourth pipeline, so that the liquid in the production water pool is pumped into the high-level water tank through the first water pump.

[0021] In some embodiments, it further includes:

[0022] The third electric valve is arranged on the third pipeline and close to the production water pool. The third electric valve is connected to the pressure sensing device and the second electric valve respectively, so that when the pressure sensing device senses a pressure less than a preset pressure, the third electric valve opens; and when the pressure sensing device senses a pressure greater than the preset pressure, the third electric valve closes.

The cooling tower is used to convert liquid into coolant. The cooling tower is connected to the high-level water tank via a first pipeline. The first outlet of the high-level water tank is higher than a preset height relative to the cooling tower. When the first electric valve is opened, the liquid in the high-level water tank can be transferred from the first outlet to the cooling tower through the first pipeline under the action of a pressure difference. The cooling tower has a first liquid level gauge, which is used to sense the liquid level of the coolant in the cooling tower.

When the liquid level sensed by the first liquid level gauge is lower than a first preset liquid level, the first electric valve changes from a closed state to an open state, thereby connecting the first pipeline between the high-level water tank and the cooling tower. The high-level water tank can transfer liquid to the cooling tower under the action of the pressure difference to replenish the liquid in the cooling tower. The cooling tower cools the liquid to form coolant, so that the coolant in the cooling tower can continuously cool the photovoltaic glass furnace production line.

[0028] Therefore, the cooling tower circulation cooling system provided in this application can continuously provide liquid to the cooling tower through the setting of a high-level water tank, avoiding the cooling tower from stopping operation or malfunctioning due to a decrease in liquid level, thereby improving the stability of the cooling circulation system and ensuring the operation of the photovoltaic glass kiln production line.

[0042] like Figures 1 to 3 As shown, the present application provides a cooling tower circulating cooling system 1, comprising:

[0043] A cooling tower 11 is used to cool the liquid into coolant. The cooling tower 11 has a first liquid level gauge 111 for sensing the liquid level in the cooling tower 11.

[0044] A high-level water tank 12 contains liquid and has a first water outlet. The height of the first water outlet is higher than the preset height of the cooling tower 11. The first water outlet of the high-level water tank 12 is connected to the cooling tower 11 through a first pipe 13.

[0045] The first electric valve 14 is arranged at the first water outlet of the high-level water tank 12 and is electrically connected to the first liquid level meter 111. When the liquid level height sensed by the first liquid level meter 111 is lower than the first preset liquid level height, the first electric valve 14 opens, and the coolant in the high-level water tank 12 is transmitted to the cooling tower 11 through the first water outlet and the first pipeline 13.

[0046] In this embodiment, the cooling tower 11 also has a water outlet pipe for outputting the coolant after cooling by the cooling tower 11. The water outlet pipe is arranged around the photovoltaic glass kiln production line 2, or the water outlet pipe is connected to the photovoltaic glass kiln production line 2, thereby realizing cooling of the photovoltaic glass kiln production line 2, thereby ensuring the normal operation of the photovoltaic glass kiln production line 2.

[0047] The present application provides a cooling tower circulating cooling system 1, comprising a cooling tower 11, a high-level water tank 12, and a first electric valve 14. The cooling tower 11 is used to convert liquid into coolant. The cooling tower 11 is connected to the high-level water tank 12 via a first pipeline 13. The first water outlet of the high-level water tank 12 is higher than a preset height relative to the cooling tower 11. When the first electric valve 14 is opened, liquid in the high-temperature water tank can be transferred from the first water outlet to the cooling tower 11 through the first pipeline 13 due to the pressure difference. The cooling tower 11 has a first liquid level gauge 111, which is used to sense the liquid level of the coolant in the cooling tower 11. The first liquid level gauge 111 is also electrically connected to the first electric valve 14 of the first water outlet of the high-level water tank 12. When the liquid level sensed by the first liquid level gauge 111 is lower than the first preset liquid level, the first electric valve 14 changes from a closed state to an open state, so that the first pipeline 13 between the high-level water tank and the cooling tower 11 is in a conducting state. The high-level water tank 12 can transmit liquid to the cooling tower 11 under the action of the pressure difference to replenish the liquid in the cooling tower 11. The cooling tower 11 cools the liquid to form a coolant, so that the coolant in the cooling tower 11 can continuously cool the photovoltaic glass kiln production line 2.

[0048] Therefore, the cooling tower circulation cooling system 1 provided in the present application can continuously provide liquid to the cooling tower 11 through the setting of the high-level water tank 12, avoiding the cooling tower 11 from stopping operation or malfunctioning due to the decrease in liquid level, thereby improving the stability of the cooling circulation system and ensuring the operation of the photovoltaic glass kiln production line 2.

[0049] In this embodiment, the high-level water tank 12 can be set on the roof of the photovoltaic glass production room.

[0050] In the embodiment of the present application, it also includes:

[0051] The second pipeline 15 has one end connected to the water supply device and the other end connected to the water inlet of the cooling tower 11 .

[0052] In this embodiment, the cooling tower circulation cooling system 1 includes a cooling tower 11, a second pipeline 15 and a water supply device. The cooling tower 11 and the water supply device are connected through the second pipeline 15, so that the water supply device can transfer liquid to the cooling tower 11 to provide liquid to the cooling tower 11, and the cooling tower 11 then cools the liquid to cool down the photovoltaic glass kiln production line 2.

[0053] In this embodiment, the water supply device is a tap water delivery device, and the liquid delivered to the cooling tower 11 is tap water.

[0054] In this embodiment, the cooling tower circulation cooling system 1 includes a cooling tower 11, a second pipeline 15, a water supply device, a high-level water tank 12 and a first electric valve 14. The cooling tower 11 and the water supply device are connected by the second pipeline 15, so that the water supply device can transfer liquid to the cooling tower 11 to provide liquid for the cooling tower 11. When the water supply device does not supply enough water to the cooling tower 11, resulting in the liquid level of the cooling tower 11 measured by the first liquid level meter 111 in the cooling tower 11 being lower than the first preset liquid level, the first electric valve 14 at the first water outlet of the high-level water tank 12 is opened, and the liquid in the high-level water tank 12 is transferred to the cooling tower 11 through the first pipeline 13 under the action of the pressure difference, thereby replenishing the liquid for the cooling tower 11, so that the cooling tower 11 can continuously provide cooling liquid to cool the photovoltaic glass kiln production line 2.

[0055] In the embodiment of the present application, it also includes:

[0056] A production water pool 16 , wherein liquid is stored in the production water pool 16 , and the production water pool 16 is connected to the second pipeline 15 via a third pipeline 17 ;

[0057] The first water pump 18 is disposed at the second water outlet of the production water pool 16 to pump the liquid in the production water pool 16 into the cooling tower 11 through the second pipeline 15 .

[0058] In this embodiment, the cooling tower circulation cooling system 1 includes a cooling tower 11, a water supply device, a second pipeline 15, a production water pool 16, a third pipeline 17 and a first water pump 18. The water supply device is connected to the cooling tower 11 through the second pipeline 15, and the second pipeline 15 is also connected to the production water pool 16 through the third pipeline 17, so that the liquid in the production water pool 16 can be pumped into the cooling tower 11 through the third pipeline 17 and the second pipeline 15 under the action of the first water pump 18, so that the water supply device and the production water pool 16 can provide liquid for the cooling tower 11, thereby further ensuring the stability of the liquid supply of the cooling tower 11, and then ensuring the stability of the cooling liquid provided by the cooling tower 11 to the photovoltaic glass kiln production line 2.

[0059] In the embodiment of the present application, it also includes:

[0060] The pressure sensing device 19 is arranged between the water supply device and the second pipe to sense the pressure of the liquid provided by the water supply device. The pressure sensing device is also electrically connected to the first water pump 18, so that when the pressure sensed by the pressure sensing device is lower than the preset pressure, the first water pump 18 is turned on to pump the liquid in the production water pool 16 into the cooling tower 11 through the second pipeline 15 and the third pipeline 17.

[0061] In this embodiment, the cooling tower circulating cooling system 1 includes a cooling tower 11, a water supply device, a second pipeline 15, a production water pool 16, a third pipeline 17, a first water pump 18, and a pressure sensor 19. The water supply device supplies liquid to the cooling tower 11 through the second pipeline 15. The pressure sensor 19 is used to detect the water supply pressure of the water supply device. When the pressure sensor 19 senses that the pressure of the liquid supplied by the water supply device to the cooling tower 11 is lower than a preset pressure, it indicates that the water supply device is supplying insufficient liquid to the cooling tower 11, and a water outage may occur. At this time, the pressure sensor 19 transmits a signal indicating that the pressure is lower than the preset pressure to the first water pump 18, which turns on the first water pump 18. Under the action of the first water pump 18, the liquid in the production water pool 16 can be pumped into the cooling tower 11 through the third pipeline 17 and the second pipeline 15, thereby compensating for the problem of reduced liquid supplied to the cooling tower 11 by the water supply device, thereby ensuring the stability of the liquid amount in the cooling tower 11.

[0062] In this embodiment, the pressure sensing device may be a pressure sensor.

[0063] In the embodiment of the present application, it also includes:

[0064] The second electric valve 20 is arranged at the third water outlet of the water supply device. The second electric valve 20 is electrically connected to the pressure sensing device so that when the pressure sensed by the pressure sensing device is lower than the preset pressure, the second electric valve 20 is closed; and when the pressure sensed by the pressure sensing device is greater than the preset pressure, the second electric valve 20 is opened.

[0065] In this embodiment, the cooling tower circulation cooling system 1 includes a cooling tower 11, a water supply device, a second pipeline 15, a production water pool 16, a third pipeline 17, a first water pump 18, a pressure sensing device 19, and a second electric valve 20. The water supply device supplies liquid to the cooling tower 11 through the second pipeline 15. The pressure sensing device 19 is used to sense the water supply pressure of the water supply device. When the pressure sensing device 19 senses that the pressure of the liquid supplied by the water supply device to the cooling tower 11 is lower than the preset pressure, it indicates that the amount of liquid supplied by the water supply device to the cooling tower 11 is insufficient, and a water outage may occur. The pressure sensing device 19 transmits the sensed pressure signal to the second electric valve 20. The second electric valve 20 is set at the third water outlet of the water supply device. After receiving the pressure signal, the second electric valve 20 closes, so that the water supply device with a stopped liquid or insufficient liquid supply no longer transmits liquid to the cooling tower 11. This avoids the sudden impact of a large amount of liquid on the cooling tower 11 after water is supplied by the water supply device, thereby improving safety. When the pressure sensing device senses that the water supply pressure of the water supply device is greater than the preset pressure, it indicates that the water supply of the water supply device is normal. At this time, the second electric valve 20 opens and continues to supply water to the cooling tower 11 through the production water pool 16, thereby continuously ensuring the water supply to the cooling tower 11.

[0066] In the embodiment of the present application, it also includes:

[0067] The second liquid level gauge 21 is arranged in the high-level water tank 12 to sense the liquid level height of the high-level water tank 12. The second liquid level gauge 21 is also connected to the first water pump 18 so that when the liquid level height sensed by the second liquid level gauge 21 is lower than the second preset liquid level height, the first water pump 18 is turned on.

[0068] In this embodiment, the cooling tower circulating cooling system 1 includes a cooling tower 11, a first liquid level gauge 111, a water supply device, a second pipeline 15, a production water pool 16, a third pipeline 17, a first water pump 18, a high-level water tank 12, a second liquid level gauge 21 and a first electric valve 14. The water supply device supplies liquid to the cooling tower 11 through the second pipeline 15. When the liquid level in the cooling tower 11 sensed by the first liquid level gauge 111 is lower than a first preset height, the liquid supply of the water supply device is insufficient or stops. The first liquid level gauge 111 transmits the sensed liquid level signal to the first electric valve 14, and the first electric valve 14 opens according to the liquid level signal, so that the high-level water tank 12 will transmit liquid to the cooling tower 11 through the first pipeline 13 under the action of the pressure difference, thereby replenishing the liquid in the cooling tower 11 and avoiding insufficient liquid in the cooling tower 11. The liquid in the high-level water tank 12 is previously stored. After a part of it is transferred to the cooling tower 11, the liquid in the high-level water tank 12 will also be insufficient. The second liquid level gauge 21 is used to sense the height of the liquid level in the high-level water tank 12. When the liquid level in the high-level water tank 12 is lower than the second preset liquid level, the liquid level signal is transmitted to the first pump body, and the first pump body is turned on. Under the action of the first pump body, the liquid in the production water pool 16 is pumped into the cooling tower 11 through the second pipeline 15 and the second pipeline 15 to further ensure sufficient liquid supply to the cooling tower 11 and avoid insufficient liquid in the cooling tower 11.

[0069] In the embodiment of the present application, the second water outlet of the production water pool 16 is further connected to the high-level water tank 12 through a fourth pipeline 22 , so that the liquid in the production water pool 16 is pumped into the high-level water tank 12 through the first water pump 18 .

[0070] In this embodiment, the production water pool 16 is also connected to the high-level water tank 12 through the fourth pipeline 22, so that when the second liquid level meter 21 senses that the liquid level in the high-level water tank 12 is low, the first pump body electrically connected to the second liquid level meter 21 is opened, and under the action of the first pump body, the production water pool 16 supplies liquid to the high-level water tank 12, thereby ensuring that there is sufficient liquid in the high-level water tank 12.

[0071] In this embodiment, the production water pool 16 can supply liquid to the high-level water tank 12 and the cooling tower 11 at the same time, or it can supply liquid to the high-level water tank 12 when the water supply device restarts water supply and the cooling tower 11 has sufficient liquid supply.

[0072] In the embodiment of the present application, it also includes:

[0073] The third electric valve 23 is arranged on the third pipeline 17 and is arranged close to the production water pool 16. The third electric valve 23 is connected to the pressure sensing device 19 and the second electric valve 20 respectively, so that when the pressure sensing device 19 senses a pressure less than a preset pressure, the third electric valve 23 opens; and when the pressure sensing device senses a pressure greater than a preset pressure, the third electric valve 23 closes.

[0074] In this embodiment, the production water tank 16 is connected to the cooling tower 11 via a third pipeline 17 and a second pipeline 15. A first water pump 18 is provided at the second water outlet of the production water tank 16, and a third electric valve 23 is provided on the third pipeline 17 near the production water tank 16. Both the first water pump 18 and the third electric valve 23 are connected to a pressure sensor 19. When the pressure sensor 19 senses that the water supply pressure of the water supply device is less than a preset pressure, the water output of the water supply device is insufficient and the cooling tower 11 cannot be fully supplied by the water supply device. In this case, water needs to be supplied to the cooling tower 11 through the production water tank 16. When the pressure sensor 19 senses that the pressure in the second pipeline 15 is less than a preset pressure, the first water pump 18 and the third electric valve 23 connected to the pressure sensor are opened upon receiving the pressure signal, allowing the production water tank 16 to supply liquid to the cooling tower 11 through the third pipeline 17 and the second pipeline 15. When the pressure sensed by the pressure sensing device is greater than the preset pressure, the water supply device can normally supply water to the cooling tower 11. At this time, the third electric valve will be closed after receiving the pressure signal from the pressure sensing device, so that the production water pool 16 will no longer supply water to the cooling tower 11, avoiding overflow and other problems caused by excessive liquid in the cooling tower 11.

[0075] In the embodiment of the present application, it also includes:

[0076] The fourth electric valve 24 is arranged on the fourth pipeline 22 and is arranged close to the production water pool 16. The fourth electric valve 24 is electrically connected to the pressure sensing device 19 and the second liquid level gauge 21 respectively, so that when the pressure sensing device 19 senses a pressure greater than the preset pressure and the liquid level height sensed by the second liquid level gauge 21 is lower than the second preset liquid level height, the fourth electric valve 24 opens.

[0077] In this embodiment, the production water pool 16 and the high-level water tank 12 are connected via a fourth pipeline 22. A fourth electric valve 24 is provided at one end of the fourth pipeline 22 near the production water pool 16. When the water supply pressure of the water supply device sensed by the pressure sensing device is greater than a preset pressure, the water supply device can normally supply water to the cooling tower 11. At this time, the third electric valve 23 on the third pipeline 17 is closed, and the production water pool 16 does not supply water to the cooling tower 11. Furthermore, when the second liquid level gauge 21 senses that the liquid level in the high-level water tank 12 is lower than a second preset liquid level, indicating a water shortage in the high-level water tank 12, the fourth electric valve 24 opens, and the production water pool 16 can supply water to the high-level water tank 12 via the fourth pipeline 22, thereby replenishing the liquid in the high-level water tank 12 and preventing a shortage of liquid in the high-level water tank 12 during the next water use.

[0078] In this embodiment, it also includes:

[0079] The fifth electric valve 25 is provided near the water inlet of the cooling tower 11 to control the opening or closing of the liquid inlet of the cooling tower 11 .

[0080] In an embodiment of the present application, when the cooling tower 11 is not needed to cool the photovoltaic glass kiln production line 2, the fifth electric valve 25 is closed to prevent the cooling tower 11 from receiving liquid and to prevent the cooling tower 11 from cooling the liquid, thereby avoiding waste of resources and saving costs.
