Description

Technical Field

[0001] This utility model relates to the technical field of cooling tower spray systems, specifically to a cooling tower spray water supply pressure stabilization structure and a cooling tower. Background Technology

[0002] In existing technology, the bottom layer of a cooling tower is an air intake layer, with multiple air dampers around its perimeter. A packing layer is installed above the air intake layer. A spray unit is installed above the packing layer, with nozzles spraying hot water to be treated onto the packing layer. Specifically, such as... Figure 1 As shown, the spray unit includes a horizontally arranged water supply pipe, and multiple nozzles are installed on the lower side of the water supply pipe, supplying hot water to the nozzles through the water supply pipe.

[0003] However, sometimes the water pressure and flow rate of the hot water supplied to the cooling tower vary, resulting in uneven water distribution among the nozzles distributed along the water supply pipe. In particular, the nozzles far from the water inlet will have less water, which reduces the heat exchange efficiency of the packing layer. Utility Model Content

[0004] This utility model addresses the aforementioned technical problems in the prior art by providing a cooling tower spray water supply pipe pressure stabilization structure and a cooling tower, which can stabilize the water pressure in the water supply pipe and make the water volume sprayed from each nozzle distributed along the water supply pipe tend to be uniform.

[0005] To achieve the above-mentioned technical objectives, one aspect of this utility model provides a pressure stabilizing structure for a cooling tower spray water supply pipe, comprising:

[0006] A water supply pipe extends horizontally inside the cooling tower, the water supply pipe having a first end and a second end disposed opposite to each other.

[0007] Multiple nozzles connected to and arranged along the water supply pipe, and

[0008] The pressure stabilizing section has an inner cavity that is connected to the water supply pipe, forming a pressure stabilizing chamber inside the pressure stabilizing section.

[0009] Furthermore, the height of the top of the pressure stabilizing chamber is higher than the height of the water supply pipe.

[0010] Furthermore, the first end is the inflow end; the second end is the closed end.

[0011] Furthermore, the pressure stabilizing unit is located at the second end near the water supply pipe.

[0012] Furthermore, the pressure stabilizing section is formed by bending the second end of the water supply pipe upwards.

[0013] Furthermore, the pressure stabilizing section is located near the middle of the water supply pipe.

[0014] Furthermore, the pressure stabilizing unit is located at the first end near the water supply pipe.

[0015] Furthermore, both the first and second ends of the water supply pipe are water inlets, and the pressure stabilizing part is located in the middle of the length direction of the water supply pipe.

[0016] Furthermore, there are multiple pressure stabilizing units arranged along the water supply pipe.

[0017] Another aspect of this utility model provides a cooling tower, including the cooling tower spray water supply pipe pressure stabilization structure described in any of the above embodiments.

[0018] One or more technical solutions provided in this embodiment of the present invention have at least the following technical effects or advantages: When water is supplied to the nozzle through the water supply pipe, a condensing cavity for accumulating compressed air is formed on the upper side of the pressure stabilizing chamber. When the water supply pressure in the water supply pipe increases, the air in the condensing cavity is compressed, thereby playing a buffering role; when the water supply pressure in the water supply pipe decreases, the compressed air in the condensing cavity expands, replenishing water to the water supply pipe, thereby playing a buffering role against water pressure fluctuations in the water supply pipe.

[0028] Other objects and advantages of this utility model will become clear by explaining the preferred embodiments of the present application below.

[0029]

Example 1

[0030] Figure 2 This is a schematic diagram of the pressure stabilizing structure of the cooling tower spray water supply pipe according to the first embodiment of this utility model.

[0031] like Figure 2 As shown, a cooling tower spray water supply pipe pressure stabilization structure includes a water supply pipe 1 extending horizontally inside the cooling tower. The water supply pipe 1 has a first end 10 and a second end 11 disposed opposite to each other. A plurality of nozzles 2 are arranged evenly along the water supply pipe 1 on its lower side. The nozzles 2 are used to spray hot water onto the packing layer below them. This embodiment also includes a pressure stabilizing part 3a, the inner cavity of which is connected to the water supply pipe 1. A pressure stabilizing chamber 30 is formed inside the pressure stabilizing part 3a, and the top of the pressure stabilizing chamber 30 is higher than the height of the water supply pipe 1.

[0032] When water is supplied to the nozzle 2 through the water supply pipe 1, a condensing cavity for compressed air is formed on the upper side of the pressure stabilizing chamber 30. When the water supply pressure in the water supply pipe 1 increases, it compresses the air in the condensing cavity, thus providing a buffering effect; when the water supply pressure in the water supply pipe 1 decreases, the compressed air in the condensing cavity expands, replenishing water into the water supply pipe 1, thereby buffering the water pressure fluctuations in the water supply pipe 1.

[0033] The first end 10 is the inflow end; the second end 11 is the closed end. The pressure stabilizing part 3a is located near the second end 11 of the water supply pipe 1. The pressure stabilizing part near the second end 11 can supplement the water volume of the nozzles 2 attached to the second end 11, thereby balancing the spraying speed of the nozzles 2 distributed along the length of the water supply pipe 1.

By bending and forming, the manufacturing cost of the pressure stabilizing structure is reduced.
