Description

Technical Field

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

[0002] A cooling tower is a tower-shaped heat dissipation device that cools water. It cools the working fluid by allowing the cooling water to come into full, direct or indirect contact with the atmosphere inside the tower, utilizing principles such as water evaporation and heat dissipation. Cooling towers are mainly divided into two types: closed-circuit cooling towers and open-circuit cooling towers. In a closed-circuit cooling tower, high-temperature water generated by the equipment is passed through pipes, and the pipes are cooled by contact with the air inside the tower. In an open-circuit cooling tower, high-temperature water is sprayed into the tower's interior, and then sprayed through spray pipes into the packing layer, where the water is cooled through contact with the air.

[0003] In existing technologies, both closed-loop and open-loop cooling towers require the high-temperature water to be under pressure before it can be delivered. Therefore, a water tank is added between the high-temperature water outlet of the workshop equipment and the cooling tower. The high-temperature water flows out of the equipment's pipes and is first stored in the tank before being pumped into the cooling tower for cooling. However, in practice, to save floor space, the cooling tower is usually placed above the water tank. While this saves floor space, it results in high pump head and high energy consumption. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a cooling tower circulation system, which solves the technical problem of high energy consumption of water pumps due to large head when the cooling tower is arranged above the water tank in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a cooling tower circulation system, comprising: Water tank with a top support; A cooling tower is installed on the top of the support. The cooling tower has an inlet and an outlet. The outlet is connected to the water tank so that water cooled by the cooling tower can enter the water tank. An intermediate tank is disposed on the top of the support and located on one side of the cooling tower. The intermediate tank has an inlet that communicates with the outside and an outlet that communicates with the water inlet. A water pump is provided between the outlet and the water inlet to pump water from the intermediate tank into the water inlet. The intermediate tank also has an overflow port that communicates with the water tank so that water overflowing from the intermediate tank can enter the water tank.

[0006] For example, in a cooling tower circulation system provided by at least one embodiment of the present invention, the intermediate box is a box structure with an open top, and the open top is the inlet.

[0007] For example, in a cooling tower circulation system provided by at least one embodiment of the present invention, a guide ramp is provided between the overflow port and the water tank so that the water flowing out of the overflow port can fall into the water tank along the guide ramp.

[0008] For example, in a cooling tower circulation system provided by at least one embodiment of the present invention, the volume ratio of the intermediate tank to the water tank is not greater than 1:10.

[0009] For example, in a cooling tower circulation system provided by at least one embodiment of the present invention, the inclination angle of the guide plate is 45~30°.

[0010] For example, in a cooling tower circulation system provided by at least one embodiment of the present invention, baffles are provided on both sides of the guide ramp, and the baffles are used to restrict the water flow path on the guide ramp.

[0011] For example, in a cooling tower circulation system provided by at least one embodiment of the present invention, filter plates are provided at both the outlet and overflow port of the intermediate box.

[0012] For example, in a cooling tower circulation system provided by at least one embodiment of the present invention, the cooling tower is an open cooling tower.

[0013] For example, in a cooling tower circulation system provided by at least one embodiment of the present invention, the cooling tower is a closed cooling tower.

[0014] The beneficial effects of this utility model are as follows: In this invention, an intermediate tank is installed on the top plate supporting the water tank. High-temperature water from the workshop equipment first enters the intermediate tank, and then a water pump directly pumps the water from the intermediate tank into the inlet of the cooling tower. After being cooled inside the cooling tower, the high-temperature water flows into the water tank for storage from the outlet. Compared to pumping water directly into the cooling tower from the bottom of the water tank, this method reduces the pump head, saves energy, and does not increase the floor space. Furthermore, the water tank is directly connected to the outlet of the cooling tower, making it a storage container for the cooling water. It can also connect the outlet of the water tank to the workshop's cooling water supply pipeline via a separate pump assembly, acting as an intermediate transition and ensuring a stable water pressure for the workshop's cooling water supply. This also reduces the need for a separate cooling water storage tank within the cooling tower itself. At the same height, the movement path of the high-temperature water inside the cooling tower is increased, thereby extending the contact area between the water and air inside the cooling tower and further improving cooling efficiency.

[0015] An overflow outlet connected to the water tank is installed in the intermediate tank. Once the water in the water tank reaches a certain volume, it can overflow from the overflow outlet and fall back into the water tank. At this point, a lower-powered water pump can be selected between the intermediate tank and the inlet to ensure that the output speed of the high-temperature water in the workshop is always greater than the pump's delivery speed. This simplifies the commissioning process of the water pump between the intermediate tank and the inlet. On the one hand, it avoids the situation where the pump's delivery speed of high-temperature water exceeds the workshop's output speed, causing the water in the intermediate tank to be completely drained. On the other hand, it avoids the situation where the pump's delivery speed of high-temperature water is less than the workshop's output speed, causing the high-temperature water in the intermediate tank to accumulate and eventually overflow and be wasted.

Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-2 As shown, this invention illustrates a cooling tower circulation system according to one embodiment, specifically including a water tank, a cooling tower, and an intermediate tank. The water tank has a supporting top and is typically rectangular or cylindrical in shape, and can be made of stainless steel to ensure good corrosion resistance and structural strength. The capacity of the water tank is determined based on the amount of high-temperature water generated by the workshop equipment in the actual usage scenario.

[0024] The cooling tower is mounted on top of a support and can be either a closed-loop or open-loop cooling tower. Taking a closed-loop cooling tower as an example, it has an inlet and an outlet. The outlet is connected to a water tank via a pipe, and valves can be installed on the pipe to control the flow and volume of water. The cooling tower contains cooling structures such as coils, and cooling is achieved through heat exchange between air and the high-temperature water inside the coils. The size and cooling capacity of the cooling tower are selected based on actual requirements.

[0025] The intermediate tank is located on top of the support, on one side of the cooling tower. It is also made of corrosion-resistant materials, such as fiberglass. It has an inlet connecting to the outside environment, which is connected to the high-temperature water outlet of the workshop equipment via a pipe. Valves can also be installed on this pipe to regulate water flow. The intermediate tank also has an outlet connecting to the cooling tower's inlet. A water pump, which can be a centrifugal pump, is installed between the outlet and the inlet, with its power determined based on the required water volume and head. The intermediate tank also has an overflow outlet connecting to the water tank. This overflow outlet can be connected via a pipe or an opening at the top of the water tank. When the water level in the intermediate tank exceeds a certain height, water can flow into the water tank through the overflow outlet.

[0026] By placing an intermediate tank on the top plate supporting the water tank, the high-temperature water from the workshop equipment first enters the intermediate tank, and then the water pump directly pumps the water from the intermediate tank into the inlet of the cooling tower. After being cooled inside the cooling tower, the high-temperature water flows into the water tank for storage from the outlet. Compared to pumping water directly into the cooling tower from the bottom of the water tank, this method reduces the pump head, saves energy, and does not increase the floor space. Furthermore, the water tank is directly connected to the outlet of the cooling tower, making it a storage container for the cooling water. It can also connect the outlet of the water tank to the workshop's cooling water supply pipeline via a separate pump assembly, acting as an intermediate transition and ensuring a stable water pressure for the workshop's cooling water supply. This also reduces the need for the cooling tower's own cooling water storage tank. At the same height of the cooling tower, the movement path of the high-temperature water inside the tower is increased, thereby extending the contact area between the water and air inside the cooling tower and further improving cooling efficiency.

[0027] An overflow outlet connected to the water tank is installed in the intermediate tank. Once the water in the water tank reaches a certain volume, it can overflow from the overflow outlet and fall back into the water tank. At this point, a lower-powered water pump can be selected between the intermediate tank and the inlet to ensure that the output speed of the high-temperature water in the workshop is always greater than the pump's delivery speed. This simplifies the commissioning process of the water pump between the intermediate tank and the inlet. On the one hand, it avoids the situation where the pump's delivery speed of high-temperature water exceeds the workshop's output speed, causing the water in the intermediate tank to be completely drained. On the other hand, it avoids the situation where the pump's delivery speed of high-temperature water is less than the workshop's output speed, causing the high-temperature water in the intermediate tank to accumulate and eventually overflow and be wasted.

[0028] Furthermore, the intermediate box has a top-opening structure, with the opening at the top serving as its inlet. High-temperature water outlet pipes extending from the workshop equipment can fall directly into the intermediate box under gravity from above. This method allows the high-temperature water to come into contact with air as it falls into the intermediate box, achieving a preliminary cooling effect.

[0029] Furthermore, a guide ramp is installed between the overflow outlet and the water tank. The guide ramp has a plate-like structure, and its length is determined by the distance between the overflow outlet and the water tank, as well as the size of the water tank, to ensure that the water flowing out of the overflow outlet can smoothly fall into the water tank. The width is designed according to the width of the overflow outlet, and is generally slightly wider than the overflow outlet to prevent water from overflowing from both sides of the guide ramp. The guide ramp is installed between the overflow outlet and the water tank, with one end tightly connected to the bottom of the overflow outlet in the middle tank, and the other end extending into the water tank near the top. The guide ramp is inclined at a certain angle to the horizontal direction, generally between 30° and 45°. The specific angle needs to be adjusted according to the actual situation to prolong the contact time between the water flow and the air, thereby reducing the temperature of the high-temperature water entering the water tank.

[0030] Furthermore, in the actual design of the cooling tower circulation system, the volumes of the intermediate tank and the main tank need to be precisely determined based on the flow rate of high-temperature water generated by the workshop equipment, the cooling tower's processing capacity, and the water storage requirements of the main tank. Preferably, the volume of the intermediate tank should not exceed 1 / 10 of the main tank volume. On the one hand, a smaller intermediate tank can reduce the space occupied on the top of the support while meeting the system's operational requirements, making more rational use of the limited installation space. At the same time, it avoids material waste caused by an excessively large intermediate tank, reducing equipment costs. On the other hand, the volume of the intermediate tank should not be less than 1 / 15 of the main tank volume; a sufficiently large main tank volume can prevent the water flow left at the overflow outlet from having a significant impact on the cooling water inside the main tank.

[0031] Furthermore, the guide ramp has baffles on both sides. These baffles are plate-like structures, fixed to the sides of the guide ramp by welding or bolting to effectively block water flow. The length of the baffles is the same as the length of the guide ramp, comprehensively restricting the water flow path. The baffles are used to limit the water flow path on the guide ramp. They effectively confine the water flow on the guide ramp within a specific path, preventing water from spreading to the sides or overflowing, ensuring that the water accurately falls into the predetermined position in the water tank. This helps to further improve water recycling rates and reduce water waste.

[0032] Optionally, the cooling tower is an open cooling tower.

[0033] The specific working principle is as follows: High-temperature water generated by the workshop equipment enters the intermediate tank through the inlet. Part of the high-temperature water in the intermediate tank is pumped into the inlet of the cooling tower, where it is sprayed onto the packing layer. Through heat exchange with the packing layer and air, the high-temperature water is cooled and flows into the water tank for storage. The water tank is connected to the workshop equipment, allowing it to supply cooling water to the equipment, thus forming a circulation.

[0034] Optionally, the cooling tower is a closed-loop cooling tower.

[0035] The specific working principle is as follows: High-temperature water generated by the workshop equipment enters the intermediate tank through the inlet. Part of the high-temperature water in the intermediate tank is pumped into the inlet of the cooling tower. The high-temperature water flows within the cooling tower's pipes, exchanging heat with the air and the cooling medium sprayed from the cooling tower to lower its temperature. Finally, it flows out through the outlet to the water tank. The water tank is connected to the workshop equipment, allowing it to supply cooling water to the equipment, thus forming a circulation.

[0036] Optionally, to prevent pump blockage, filter plates can be added to the outlet and overflow ports of the intermediate tank to trap impurities in the high-temperature water flowing from the workshop equipment. The intermediate tank also facilitates the removal of impurities; compared to cleaning large water tanks, regular cleaning of the intermediate tank is easier and more convenient for routine equipment maintenance.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
