Description

Technical Field

[0001] This utility model relates to cooling tower technology, and more particularly to an energy-saving cooling tower that prevents the water collection tray from freezing in winter. Background Technology

[0002] Currently, to prevent the water in the cooling tower's collection basin from freezing in winter and affecting its operation, a common measure is to install electric heating. In winter, buildings with cooling needs, such as high-end hotels, commercial establishments, and hospitals, typically have electric heating devices installed in the cooling tower's collection basin or pool to ensure the cooling tower can still operate normally in low-temperature environments. Electric heating of the cooling tower's collection basin usually uses groups of electric heating rods. These heating rods are installed in the collection basin and convert electrical energy into heat energy to prevent the water from freezing.

[0003] Existing technologies reveal that existing energy-saving cooling towers that prevent water pan freezing in winter employ electric heaters to protect the water pan from freezing. However, the use of electric heaters presents the following problems:

[0004] The power of electric heaters typically accounts for about 15% of the total power of a cooling tower. Using electric heating consumes a lot of energy. A cooling tower is a heat dissipation device, and relying solely on external supplementary energy to maintain the temperature is an extra and very inefficient way to conserve energy.

[0005] Additional fire safety considerations are necessary. Since the heating element is exposed while heating water, it must be installed away from flammable materials to ensure heating occurs only in water and prevent fires. Continuous heating without water can cause the heating element to overheat and burn out, leading to a fire. Always pay attention to the liquid level protection when using electric heating; a damaged level gauge can cause dry burning, damaging the heater and increasing maintenance costs.

[0006] The design of the electrical control circuit also requires special attention to avoid frequent start-up and shutdown of the heater due to improper control, which could damage the electrical control equipment. The electric heater must be equipped with a leakage current switch and an automatic switch, and must be connected to high voltage with a tight seal to meet the requirements for underwater operation, as there is a potential risk of electric leakage.

[0032] like Figure 1-4As shown, an energy-saving cooling tower for preventing the water collection tray from freezing in winter includes a cooling tower housing assembly 10, a first circulation line 200, and a second heating line 300. The top of the cooling tower housing assembly 10 has two water distribution trays 60 distributed at both ends of the top. Each water distribution tray 60 has multiple water passage holes 61 evenly distributed. The two water distribution trays 60 are respectively equipped with a first cooling water pipe 30 and a second cooling water pipe 40. The cooling tower housing assembly 10 has multiple side packings 20 inclined along both sides. A bottom water collection tray 11 is provided at the bottom of the cooling tower housing assembly 10. The first circulation line 200 includes a lower edge circulation pipe 201, a first solenoid valve 2010, a bottom circulation line 203, and an upper edge circulation pipe 2031. The lower edge circulation pipe 201 connects to the first cooling water pipe 300. The cooling water pipe 30 is connected, and the first solenoid valve 2010 is set on the lower edge circulation pipe 201. The lower edge circulation pipe 201, the bottom circulation line 203, and the upper edge circulation pipe 2031 are connected in sequence. The bottom circulation line 203 is arranged around the inner wall of the bottom water collection plate 11, and the end of the upper edge circulation pipe 2031 is connected to the water distribution plate 60. The second heating line 300 includes a lower edge pipe 301, a second solenoid valve 3010, and a water outlet pipe 302. The lower edge pipe 301 is connected to the second cooling water pipe 40, the second solenoid valve 3010 is set on the lower edge pipe 301, the lower edge pipe 301 is connected to the water outlet pipe 302, and the end of the water outlet pipe 302 is connected to the bottom water collection plate 11. By using a solenoid valve to control the switching of the pipeline, on the one hand, the circulating water from the high-temperature cooling tower can indirectly heat the bottom water collection tray 11 by flowing through the first circulation line 200 and then flow back to the water distribution tray 60; on the other hand, the circulating water from the high-temperature cooling tower can flow through the second heating line 300 and then flow into the bottom water collection tray 11 for direct heating, thus solving the problems of high energy consumption and high risk.

[0033] Specifically, the bottom water collection tray 11 is equipped with a water outlet.

[0034] In a preferred embodiment of the first aspect of this utility model, the first circulation line 200 further includes a bottom support frame 204, which has multiple notches for placing pipes. Specifically, in this embodiment, each bottom support frame 204 has three notches for placing pipes.

[0035] In a preferred embodiment of the first aspect of this utility model, the water distribution plate 60 is rectangular. The water passage hole 61 is circular. The bottom circulation line 203 is rectangular in shape. The bottom circulation line 203 is provided with 3-6 layers of pipes. Specifically, in this embodiment, the bottom circulation line 203 is provided with 3 layers of pipes.

[0036] In a first aspect of this utility model, as a preferred embodiment, the surface of the bottom water collection tray 11 is parallel to the water distribution tray 60. The cooling tower housing assembly 10 is cuboid.

[0037] It should be noted that the control logic of this application is as follows:

[0038] In winter, when the temperature sensor in the water collection pan determines that the water temperature is ≤5℃, the water collection pan needs to be heated. The system then controls the branch pipe valve to open, and closes the valve to stop working when the water temperature reaches the set temperature.

[0039] If the minimum temperature cannot be maintained after the solenoid valve is opened, the system automatically opens the solenoid valve simultaneously, and the water from the bypass branch pipe flows directly into the water collection pan for direct heating. Heating and freezing the water collection pan directly through the high-temperature cooling water inlet main pipe is simple in structure, low in cost, and avoids the high energy consumption of electric heaters.

[0040] In summary, this application has the following beneficial effects:

[0041] 1. Reduces energy consumption, saves operating costs, and promotes energy conservation and emission reduction;

[0042] 2. It avoids the risk of electric leakage from electric heaters;

[0043] 3. Lower failure rate and longer service life; simple piping avoids the damage costs caused by dry burning of electric heaters at low water levels.

[0044] 4. Easy to maintain and clean. For 304 stainless steel, you only need to clean the outer surface of the coil when routinely cleaning the water collection pan.

[0045] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
