Description

Technical Field

[0001] This utility model relates to the field of cooling tower equipment technology, specifically a constant pressure circulating water cooling tower system. Background Technology

[0003] The invention patent with announcement number CN113834346A discloses a constant pressure circulating water cooling tower system. This patent adds a hot water storage tank and a water pressure balancer to the original cooling tower system. When the water flow into the hot water port of the water pressure balancer is too large, some of it will flow out from the water channel to the hot water storage tank, thus ensuring that the water pressure drawn by the hot water pump from the hot water pump port is not too high. When the water flow into the hot water port of the water pressure balancer is too small, some of it will be drawn from the hot water storage tank to the hot water pump through the water channel, thus ensuring that the water pressure drawn by the hot water pump from the hot water pump port is not too low.

[0004] However, in the implementation of this patent, excess hot water is stored inside a hot water storage tank. The hot water storage tank cannot pre-cool the hot water, and it cannot work with the cooling tower to cool the hot water, which greatly reduces the cooling efficiency of the cooling tower system. Therefore, this utility model provides a constant pressure circulating water cooling tower system to solve the above problems. Utility Model Content

A microcontroller is installed on the top of the distribution water storage tank, and a distribution compartment is installed at the end of the distribution water storage tank away from the cooling tower body. Three sets of third solenoid valves are evenly installed on the top of the distribution compartment, and a second solenoid valve is installed at the end of the distribution compartment away from the distribution water storage tank. The system includes a second water pump installed at the bottom of the diversion storage tank near the diversion compartment, a liquid pressure sensor installed at the bottom of the constant pressure storage tank near the cooling tower body, a first water pump installed at the top of the constant pressure storage tank, and a first solenoid valve installed at the bottom of the constant pressure storage tank away from the cooling tower body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The constant pressure circulating water cooling tower system is equipped with a distribution water storage tank, a constant pressure water storage tank, a guide pipe, and a second water pump. During use, if the water pressure inside the constant pressure water storage tank is high, some hot water can be diverted to the distribution water storage tank through the guide pipe to reduce the water pressure inside the constant pressure water storage tank. When the water pressure inside the constant pressure water storage tank is low, the second water pump can pump the hot water stored in the distribution water storage tank back into the constant pressure water storage tank to increase the water pressure inside the constant pressure water storage tank. This helps to keep the water pressure inside the constant pressure water storage tank constant, so that when the first water pump pumps hot water into the cooling tower body, the water pressure at the inlet of the first water pumping pipe remains constant.

[0015] 2. The constant pressure circulating water cooling tower system is equipped with a microcontroller and a liquid pressure sensor.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides an embodiment of a constant pressure circulating water cooling tower system, comprising a cooling tower body 1, a distribution water storage tank 2, a constant pressure water storage tank 5, and a distribution chamber 14. The constant pressure water storage tank 5 is installed on the top of one end of the cooling tower body 1, and the distribution water storage tank 2 is installed on the bottom of the cooling tower body 1 near the constant pressure water storage tank 5. A microcontroller 3 (e.g., HT66F018) is installed on the top of the distribution water storage tank 2. The distribution chamber 14 is installed on the end of the distribution water storage tank 2 away from the cooling tower body 1. The top of the distribution chamber 14 is... Three sets of third solenoid valves 19 are evenly installed. The model of the third solenoid valve 19 here can be HYZF2-15. A second solenoid valve 13 is installed at the end of the distribution chamber 14 away from the distribution water storage tank 2. The model of the second solenoid valve 13 here can also be HYZF2-15. A second water pump 15 is installed at the bottom of the distribution water storage tank 2 near the end of the distribution chamber 14. The model of the second water pump 15 here can be ISGD. A liquid pressure sensor 4 is installed at the bottom of the constant pressure water storage tank 5 near the end of the cooling tower body 1. The model of the liquid pressure sensor 4 here can also be... The HG-SOP8150 constant pressure water storage tank 5 has a first water pump 8 installed on its top. The first water pump 8 can be an ISGD model. The input end of the first water pump 8 is connected to a first water pipe 6 extending into the constant pressure water storage tank 5, and the output end of the first water pump 8 is connected to a first water outlet pipe 7 extending into the cooling tower body 1. The first water pump 8 draws hot water from inside the constant pressure water storage tank 5 through the first water pipe 6 and pumps the hot water into the cooling tower body 1 through the first water outlet pipe 7 for cooling. The constant pressure water storage tank 5 is located away from the cooling tower. A first solenoid valve 11 is installed at the bottom of one end of the main body 1. The model of the first solenoid valve 11 can be HYZF2-15. The output end of the liquid pressure sensor 4 is electrically connected to the input end of the microcontroller 3 through a wire. The output end of the microcontroller 3 is electrically connected to the input ends of the first water pump 8, the first solenoid valve 11, the second solenoid valve 13, the second water pump 15 and the third solenoid valve 19 through wires respectively. A water inlet pipe 9 is installed at the top of the constant pressure water storage tank 5 away from the cooling tower main body 1. Hot water can enter the interior of the constant pressure water storage tank 5 through the water inlet pipe 9.

[0023] like Figure 1-2As shown, a guide pipe 12 is installed at the output end of the first solenoid valve 11, and the end of the guide pipe 12 away from the first solenoid valve 11 is connected to the diversion water storage tank 2. The microcontroller 3 controls the first solenoid valve 11 to open, so that the water inside the constant pressure water storage tank 5 is diverted to the diversion water storage tank 2 through the guide pipe 12, thereby reducing the water pressure inside the constant pressure water storage tank 5.

[0024] like Figure 1-2 As shown, the input end of the second water pump 15 is equipped with a second water pumping pipe 16 extending into the diversion storage tank 2, and the output end of the second water pump 15 is equipped with a second water outlet pipe 17 extending into the diversion chamber 14. The output ends of the third solenoid valve 19 are all equipped with cooling water pipes 18, and the ends of the cooling water pipes 18 away from the third solenoid valve 19 are all connected to the diversion storage tank 2. The second water pump 15 can pump the hot water in the diversion storage tank 2 into the diversion chamber 14 and divert the hot water to multiple sets of cooling water pipes 18. The hot water can exchange heat with the outside air through the cooling water pipes 18, so that the heat inside the hot water can be quickly dissipated. The hot water can be pre-cooled. When used in conjunction with the cooling tower body 1, it is beneficial to improve the cooling efficiency of the device.

[0025] like Figure 1-2 As shown, a water supply pipe 10 is installed at the output end of the second solenoid valve 13, and the end of the water supply pipe 10 away from the second solenoid valve 13 is connected to the constant pressure water storage tank 5. Hot water flows back to the inside of the constant pressure water storage tank 5 through the water supply pipe 10, which can replenish the water inside the constant pressure water storage tank 5, thereby keeping the water pressure inside the constant pressure water storage tank 5 constant.

[0026] Working principle:

[0027] When in use, the device is connected to the power supply, and hot water enters the constant pressure water storage tank 5 through the inlet pipe 9. The first water pump 8 draws out the hot water from the constant pressure water storage tank 5 through the first water pumping pipe 6, and draws the hot water into the cooling tower body 1 through the first outlet pipe 7 for cooling.

[0028] During use, the liquid pressure sensor 4 monitors the water pressure inside the constant pressure water tank 5 in real time and transmits the monitored information to the microcontroller 3, which then controls the device.

[0029] When the water pressure inside the constant pressure water tank 5 is higher than the preset threshold of the microcontroller 3, the microcontroller 3 controls the first solenoid valve 11 to open, so that the water inside the constant pressure water tank 5 is diverted to the diversion water tank 2 through the diversion pipe 12, thereby reducing the water pressure inside the constant pressure water tank 5.

[0030] At the same time, the microcontroller 3 controls the second water pump 15 and the third solenoid valve 19 to start, and controls the second solenoid valve 13 to close. At this time, the second water pumping pipe 16 draws the hot water inside the diversion storage tank 2 into the diversion chamber 14, so that the hot water is diverted to multiple sets of cooling water pipes 18, and then flows back to the diversion storage tank 2 through the cooling water pipes 18, so that the hot water inside the diversion storage tank 2 circulates.

[0031] Hot water can exchange heat with the outside air through cooling water pipe 18, which allows the heat inside the hot water to dissipate quickly. This can pre-cool the hot water and, when used in conjunction with the cooling tower body 1, improve the cooling efficiency of the device.

[0032] When the water pressure inside the constant pressure water storage tank 5 is lower than the preset threshold of the microcontroller 3, the microcontroller 3 controls the first solenoid valve 11 to close, preventing the water inside the constant pressure water storage tank 5 from continuing to flow into the diversion water storage tank 2.

[0033] At the same time, the microcontroller 3 controls the second water pump 15 and the second solenoid valve 13 to start, and controls the third solenoid valve 19 to close. At this time, the second water pumping pipe 16 draws the hot water inside the diversion storage tank 2 into the diversion chamber 14, so that the hot water flows back to the constant pressure storage tank 5 through the water replenishment pipe 10, thereby replenishing the constant pressure storage tank 5 and keeping the water pressure inside the constant pressure storage tank 5 constant.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
