Description

Technical Field

[0001] The utility model belongs to the technical field of cooling towers, and particularly relates to a hydraulic pressure stabilizing and flow equalizing device for a variable flow cooling tower. Background Art

[0002] In the existing market, the main pipe of the water inlet pipe of a cooling tower is generally arranged below the side of the cooling tower, and is piped along one side or both sides of the cooling tower, and then the branch pipes are respectively arranged according to the positions of the water inlet ports of each cooling tower module, so as to achieve the purpose of supplying water to the water inlet ports. Such a design has complex water inlet pipe layouts and too many branch pipes, resulting in unbalanced water power. Often, the water inflow of the branch pipes close to the main pipe is large, while the water inflow of the branch pipes far from the main pipe is small or even there is no water. Eventually, the water inflow is unbalanced, greatly reducing the water spraying uniformity of the packing under the water distribution tank and seriously affecting the energy efficiency of the cooling tower. Summary of the Utility Model

[0003] In order to solve the problems of unbalanced and uneven water power in the water distribution tank pipeline and improve the energy efficiency of the cooling tower, the inventor has developed a hydraulic pressure stabilizing and flow equalizing device for a variable flow cooling tower based on the rich experience accumulated in the technical field of cooling towers.

[0004] To achieve the above object, the utility model provides the following technical solution: A hydraulic pressure stabilizing and flow equalizing device for a variable flow cooling tower, comprising: a water inlet device, the water inlet device is provided with a housing, the top of the housing is connected with a water inlet, the right side of the housing is connected with a first communication port, and the left side of the housing is connected with a second communication port; an overflow device, the overflow device is sleeved inside the water inlet device, the overflow device is provided with an overflow pipe, the top of the overflow pipe is provided with an overflow port, a end cap is installed on the top of the overflow port, a gap for the flow of the water supply body is formed between the outer wall of the overflow pipe and the inner wall of the housing, the bottom of the overflow pipe is connected with a water outlet, and the bottom of the housing is welded to the outer wall of the overflow pipe.

[0005] Further, the first communication port and the second communication port are on the same horizontal plane.

[0006] Further, the height of the overflow port is H1, the height of the first communication port and the second communication port is H2, H1 > H2, and H1 is at least 5 cm higher than H2. In the hydraulic pressure stabilizing and flow equalizing device designed in the utility model, it must be ensured that water cannot flow out from the water outlet before the water levels in each hydraulic pressure stabilizing and flow equalizing device reach equilibrium. Therefore, it is necessary to ensure that the highest point of the overflow port is higher than the highest point of the communication port. In this way, when the water levels in all hydraulic pressure stabilizing and flow equalizing devices are the same, the water flow will flow out from the overflow port, thus ensuring that the water output of each hydraulic pressure stabilizing and flow equalizing device is basically the same.

[0007] Further, a ventilation pipe is connected to the right side of the housing, and the tail of the ventilation pipe faces upward. The inside of the hydraulic pressure stabilizing flow equalizer cannot be closed, but is communicated with the atmosphere through the ventilation pipe. The water outlet of the hydraulic pressure stabilizing flow equalizer is not due to the pressure of the water pump, but due to the overflow of water formed by natural gravity.

[0008] Further, the end cap is welded to the top of the overflow port. The diameter of the end cap is larger than that of the overflow pipe, and the end cap is arc-shaped. The function of the end cap is to block the water from directly entering the overflow pipe when water enters, but to flow into the connecting pipe through the space between the housing and the overflow pipe, and then flow to other hydraulic pressure stabilizing flow equalizers through the connecting pipe.

[0009] Compared with the prior art, the present utility model has the following beneficial effects:

[0010] By installing a hydraulic pressure stabilizing flow equalizer on each water distribution tank, the hydraulic pressure stabilizing flow equalizer includes a water inlet device and an overflow device, which can well improve the phenomena of unbalanced pipeline hydraulic pressure and uneven hydraulic pressure, ensure the water distribution uniformity, and improve the energy efficiency of the cooling tower.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Such as Figures 1 to 4As shown in the figure, the utility model provides a hydraulic pressure stabilizing and flow equalizing device for a variable flow cooling tower, including: an inlet device, the inlet device is provided with a housing 1, the top of the housing 1 is connected with an inlet 2, the right side of the housing 1 is connected with a first communication port 4, and the left side of the housing 1 is connected with a second communication port 5; an overflow device, the overflow device is sleeved inside the inlet device, the overflow device is provided with an overflow pipe 6, the top of the overflow pipe 6 is provided with an overflow port 7, the top of the overflow port 7 is installed with an end cap 8, a gap 10 for the water body to flow is formed between the outer wall of the overflow pipe 6 and the inner wall of the housing 1, the bottom of the overflow pipe 6 is connected with an outlet 9, and the bottom of the housing 1 is welded to the outer wall of the overflow pipe 6.

[0018] In this embodiment, the first communication port 4 and the second communication port 5 are on the same horizontal plane.

[0019] In this embodiment, the height of the overflow port 7 is H1, the height of the first communication port 4 and the second communication port 5 is H2, H1 > H2, and H1 is at least 5 cm higher than H2. In the hydraulic pressure stabilizing and flow equalizing device designed in the utility model, it must be ensured that water cannot flow out from the outlet 9 before the water levels in each hydraulic pressure stabilizing and flow equalizing device reach equilibrium. Therefore, it is necessary to ensure that the highest point of the overflow port 7 is higher than the highest point of the communication port. In this way, when the water levels in all hydraulic pressure stabilizing and flow equalizing devices are the same, the water will flow out from the overflow port 7, thus ensuring that the water output of each hydraulic pressure stabilizing and flow equalizing device is basically the same.

[0020] In this embodiment, the right side of the housing 1 is connected with a vent pipe 3, and the tail of the vent pipe 3 faces upward. The inside of the hydraulic pressure stabilizing and flow equalizing device cannot be closed, but is communicated with the atmosphere through the vent pipe 3. The water output of the hydraulic pressure stabilizing and flow equalizing device is not achieved by the pressure of a water pump, but by the effect of water overflowing due to natural gravity.

[0021] In this embodiment, the end cap 8 is welded to the top of the overflow port 7, the diameter of the end cap 8 is larger than the diameter of the overflow pipe 6, and the end cap 8 is arc-shaped. The function of the end cap 8 is to block the water from directly entering the overflow pipe 6 when water enters, but to flow into the first communication pipe 4 and the second communication port 5 through the gap between the housing 1 and the overflow pipe 6, and then flow to other hydraulic pressure stabilizing and flow equalizing devices through the first communication pipe 4 and the second communication port 5.

[0022] When the utility model is in specific use, first start the water pump. Due to the limited space of the attached drawings, the water pump is not drawn in the attached drawings, but this does not affect the understanding of the application documents by those skilled in the art. The water flow enters the water inlet 2 under the action of the water pump. Because of the setting of the end cap 8, the water flow will not enter the overflow pipe 6, but flows into the first connecting pipe 4 and the second connecting pipe 5 through the gap 10 between the outer shell 1 and the overflow pipe 6, and then flows to other hydraulic pressure stabilizing flow equalizers through the first connecting pipe 4 and the second connecting pipe 5. As the water pump continuously conveys water, the water levels in multiple hydraulic pressure stabilizing flow equalizers rise synchronously. When the water levels in multiple hydraulic pressure stabilizing flow equalizers are higher than the overflow port 7, the water flow overflows from the overflow port 7 and is discharged through the water outlet 9, so as to ensure that the water output of each hydraulic pressure stabilizing flow equalizer is basically the same, achieving the purpose of improving the energy efficiency of the cooling tower.
