Description

Technical Field

[0001] This application relates to the technical field of cooling tower hydraulic balance systems, and in particular to a hydraulic pressure stabilizing device that can be installed in multiple modes in a cooling tower. Background Technique

[0002] A cooling tower mainly uses water distribution nozzles to evenly distribute cooling water on the packing layer. Through forced convection of the fan, air is passed through the packing layer, and mass transfer and heat transfer between water and air and convective heat transfer of air occur during the contact process, so that the heat in the water is transferred from the water to the air through mass transfer and heat transfer, which is an evaporation cooling device.

[0003] However, when the inlet water flow rate of the cooling tower changes, it is not easy to balance the inlet water flow rates between each group of cooling towers. Some towers have more inlet water, some towers have less inlet water, and there may even be a phenomenon of no water. Although electric balance valves and manual regulating valves are generally installed in the existing cooling water inlet pipeline system for adjustment, due to the complex operation control, high mechanical failure rate, and poor reliability of the electric balance valves of multiple groups of cooling towers, it is very difficult to achieve uniform adjustment between the cooling tower groups, thus affecting the uniform water distribution between the cooling tower groups and further affecting the heat dissipation effect of the cooling towers. In order to balance the water inlet volume between each group of towers and fully improve the hydraulic distribution balance of each tower to improve the heat exchange rate of the cooling tower, a cooling tower hydraulic balance device came into being.

[0004] However, for the existing technology, the applicant found that in the renovation of existing engineering projects, the existing hydraulic pressure stabilizing device usually has bottom inlet and side outlet, and the inlet and outlet methods are single. Therefore, it is necessary to bend the pipe three or more welds on the cooling water main (branch) pipe, and two or three more welds need to be added between the side outlet pipe and the cooling tower water distribution tray to adapt to different working conditions. Since adding straight pipes and elbows will limit the on-site pipe laying conditions, there will be insufficient installation distance for the standby electric valve and manual regulating valve on the water inlet side of the hydraulic pressure stabilizing device, resulting in an increase in the overall installation and renovation workload, and even the phenomenon of replacing the entire water inlet pipe in multiple places, greatly increasing the material use and increasing the construction and installation cost. Utility Model Content

[0005] In order to adapt to different process pipe laying methods, facilitate installation, and reduce the construction and installation cost, this application provides a hydraulic pressure stabilizing device that can be installed in multiple modes in a cooling tower.

[0007] A hydraulic pressure stabilizing device that can be installed in multiple modes in a cooling tower, which is installed on the water distribution tray of the cooling tower at the top of the cooling tower. It includes an outer sleeve and an inner sleeve. The inner sleeve is sleeved inside the outer sleeve.

[0009] Optionally, the total area of the water permeable holes is greater than the inner diameter cross-sectional areas of the inner sleeve, the first side water passing section and the second side water passing section.

[0010] Optionally, an air vent connecting rod is provided on the inner sleeve. One end of the air vent connecting rod is fixedly communicated with the top end wall of the inner sleeve, and the other end penetrates through the top end wall of the outer sleeve for balancing air pressure.

[0011] Optionally, a breathing valve is provided on the air vent connecting rod. The breathing valve is installed on the end face of the air vent connecting rod extending out of the outer sleeve.

[0012] Optionally, a visual liquid level mechanism is further provided on the outer sleeve for observing the change of the internal water flow rate.

[0013] Optionally, the visual liquid level mechanism includes a visual liquid level tube, a liquid level water passing section and a liquid level pressure permeable section.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1.

Detailed Description of the Embodiments

[0023] The following further elaborates on the present application in conjunction with the attached Figures 1-3 for a more detailed description.

[0024] The embodiments of the present application disclose a hydropneumatic pressure stabilizing device that can be installed in multiple modes in a cooling tower.

[0025] Embodiment 1

[0026] Referring to Figure 1 , a hydropneumatic pressure stabilizing device that can be installed in multiple modes in a cooling tower is installed on the cooling tower water distribution tray at the top of the cooling tower, including an outer sleeve 1 and an inner sleeve 2. The inner sleeve 2 is sleeved inside the outer sleeve 1. The bottom end face of the inner sleeve 2 is horizontal with the bottom end face of the outer sleeve 1, and there is a certain distance between the top outer wall of the inner sleeve 2 and the top inner wall of the outer sleeve 1. A connecting ring 3 is provided at the bottom of the inner sleeve 2 and the bottom of the outer sleeve 1. The connecting ring 3 is sleeved between the bottom outer wall of the inner sleeve 2 and the inner part of the bottom of the outer sleeve 1 and is fixedly connected to the inner sleeve 2 and the outer sleeve 1 respectively.

[0027] The outer sleeve 1 is provided with a first side water passing section 4 and a second side water passing section 5. One end of the first side water passing section 4 penetrates through the lower barrel wall of the outer sleeve 1 and is fixedly communicated with the lower barrel wall of the inner sleeve 2, and the second side water passing section 5 is fixedly communicated with the lower barrel wall of the outer sleeve 1. Flange plates are sleeved and installed at the ends of the first side water passing section 4 and the second side water passing section 5 far away from the outer sleeve 1. In this embodiment, the length directions of the first side water passing section 4 and the second side water passing section 5 are the same, and the heights in the horizontal direction are the same.

[0028] Several water permeable holes 21 are opened on the barrel wall of the inner sleeve 2. In this embodiment, the water permeable holes 21 are arranged in an array along the vertical direction. The horizontal heights of the uppermost barrel walls of the first side water passing section 4 and the second side water passing section 5 are both lower than the lowest water permeable hole 21. At the same time, the total area sum of the water permeable holes 21 is greater than the inner diameter cross-sectional areas of the inner sleeve 2, the first side water passing section 4 and the second side water passing section 5, so that when the water flow surges, the incoming water preferentially passes through the water permeable holes 21, reducing the occurrence of water flushing to the top.

[0029] An air vent connecting rod 7 is arranged on the inner sleeve 2. The air vent connecting rod 7 is located between the outer wall of the top of the inner sleeve 2 and the inner wall of the top of the outer sleeve 1, and is arranged along the same length direction as the inner sleeve 2. One end of the air vent connecting rod 7 is fixedly communicated with the top end wall of the inner sleeve 2, and the other end penetrates through and extends out of the top end wall of the outer sleeve 1.

[0030] A breathing valve 8 is arranged on the air vent connecting rod 7. The breathing valve 8 is installed on the end face of the air vent connecting rod 7 extending out of the outer sleeve 1, and is respectively communicated with the inside of the air vent connecting rod 7 and the outside. The breathing valve 8 only exhales and does not let water out, while balancing the internal air pressures of the outer sleeve 1 and the inner sleeve 2, and avoiding water overflow at the top of the outer sleeve 1, causing waste of water resources.

[0031] A visible liquid level mechanism 9 is also arranged on the outer sleeve 1. The visible liquid level mechanism 9 includes a visible liquid level tube 91, a liquid level water passing section 92 and a liquid level pressure transmitting section 93. The liquid level water passing section 92 is installed on the lower barrel wall of the outer sleeve 1 and is communicated with the outer sleeve 1. The liquid level pressure transmitting section 93 is installed on the upper barrel wall of the outer sleeve 1 and is communicated with the outer sleeve 1. The visible liquid level tube 91 is installed between the liquid level water passing section 92 and the liquid level pressure transmitting section 93, and is fixedly communicated with the liquid level water passing section 92 and the liquid level pressure transmitting section 93 respectively.

[0032] Among them, a pressure relief hole 71 is opened on the air vent connecting rod 7. The pressure relief hole 71 is located on the barrel wall of the air vent connecting rod 7 inside the outer sleeve 1, reducing the pressure disturbance caused by the air in the barrel changing with the water level during water inlet and outlet to the liquid in the visible liquid level tube 91, ensuring the positive and negative pressure balance of the water level in the visible liquid level tube 91 and enabling it to fluctuate freely. The height of the pressure relief hole 71 is always higher than the height of the liquid level pressure transmitting section 93, so that when the water flow surges, the pressure relief hole 71 will not be flooded by water earlier than the liquid level pressure transmitting section 93.

[0033] Among them, during the operation of the hydraulic pressure stabilizing device that can be installed in multiple modes in the cooling tower, when the water level in the outer sleeve 1 rises and falls, water enters the visible liquid level tube 91 through the liquid level water passing section 92, and under the cooperation of the liquid level pressure passing section 93, the water level in the visible liquid level tube 91 is the same as the water level in the outer sleeve 1 and changes synchronously. The operator can judge the water flow situation inside the outer sleeve 1 according to the water level change of the visible liquid level tube 91.

[0034] Reference Figure 1 , a detachable blind plate 6 is also provided on the outer sleeve 1. In this embodiment, to achieve the effect of side water inlet and side water outlet according to the on-site working conditions. The detachable blind plate 6 is flange-connected to the connecting ring 3 to seal the bottom of the inner sleeve 2 and the outer sleeve 1. The first side water passing section 4 is flange-connected to the water inlet pipe of the cooling tower water distribution tray at the top of the cooling tower through the flange at the end far from the outer sleeve 1 and is communicated. The second side water passing section 5 is flange-connected to the water distribution tray connecting pipe of the cooling tower water distribution tray at the top of the cooling tower through the flange at the end far from the outer sleeve 1 and is communicated.

[0035] Among them, after the cooling water flows from the side to the first side water passing section 4, it enters the inner sleeve 2, and then gradually flows upward from the bottom of the inner sleeve 2 through each water permeable hole 21 on the inner cylinder wall and flows out evenly into the annular cavity between the inner and outer cylinders, and flows out through the second side water passing section 5 and enters the water outlet pipe of the water distribution tray at the upper end of the cooling tower.

[0036] Embodiment 2

[0037] Reference Figure 2 , different from Embodiment 1, in this embodiment, to achieve the effect of bottom water inlet and side water outlet according to the on-site working conditions. The detachable blind plate 6 is flange-connected to the flange of the end of the first side water passing section 4 far from the outer sleeve 1 to seal the first side water passing section 4. The water inlet pipe of the cooling tower water distribution tray at the top of the cooling tower is flange-connected to the connecting ring 3 and is communicated with the inner sleeve 2. The second side water passing section 5 is flange-connected to the water outlet pipe flange of the cooling tower water distribution tray at the top of the cooling tower through the flange at the end far from the outer sleeve 1 and is communicated.

[0038] Among them, after the cooling water flows from the lower part to the inner sleeve 2, it gradually flows upward from the bottom of the inner sleeve 2 through each water permeable hole 21 on the inner cylinder wall and flows out evenly into the annular cavity between the inner and outer cylinders, and flows out through the second side water passing section 5 and enters the water outlet pipe of the water distribution tray at the upper end of the cooling tower.

[0039] Embodiment 3

[0040] Reference Figure 3, different from the first and second embodiments, in this embodiment, according to the on-site working conditions, the effect of side water inlet and bottom water outlet is achieved. The detachable blind plate 6 is flange-connected to the flange of the end of the first side water passage section 4 away from the outer sleeve 1 to close the first side water passage section 4. The second side water passage section 5 is flange-connected to and communicated with the water inlet pipe of the cooling tower water distribution tray at the top of the cooling tower through the flange at the end away from the outer sleeve 1. The water outlet pipe of the cooling tower water distribution tray at the top of the cooling tower is flange-connected to the connecting ring 3 and communicated with the inner sleeve 2.

[0041] Among them, after the cooling water flows from the side to the second side water passage section 5 and then into the inner sleeve 2, it enters the annular cavity between the outer sleeve 1 and the inner sleeve 2. As the water level in the annular cavity rises, the cooling water gradually passes upward through each water permeable hole 21 on the inner cylinder wall and uniformly flows into the inner sleeve 2, flows out through the inner sleeve 2, and enters the water outlet pipe of the water distribution tray at the upper end of the cooling tower.
