Description

Technical Field

[0001] The utility model relates to the technical field of countercurrent cooling tower accessory devices, in particular to an exhaust device for a cooling tower water distribution system. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere to reduce the water temperature. Its working principle is mainly to generate steam through the heat exchange between water and air flow, and the steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer, thereby dissipating the waste heat generated in industry or refrigeration and air conditioning.

[0003] Existing cooling towers, such as the prior art with application number CN202221497437.7, include a motor, a motor foot, an upper shell, a water distribution system, a water inlet, a water distribution branch, an inspection door, an automatic water replenishment device, an air inlet window, an inspection escalator, a tower foot, a fan, a water collector and a nozzle, etc., and a small-hole FRP molded grid filler is arranged on the filler bracket in the vertical position of the water distribution main pipe of the square open countercurrent cooling tower as a maintenance walkway, which not only maintains the ventilation of the fan, reduces the ventilation resistance to ensure the ventilation volume, but also avoids the wall flow phenomenon of the cooling tower.

[0004] However, the water distribution systems in the prior art are not equipped with exhaust pipes, and the spraying performance of the cooling tower water distribution system is low, and the water pressure of the water distribution system is unstable, which reduces the practicality. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an exhaust device for a cooling tower water distribution system, which is convenient for improving the spraying performance of the water distribution system in the cooling tower body and stabilizing the water pressure of the water distribution system.

[0006] The utility model discloses an exhaust device for a cooling tower water distribution system, comprising a main body structure and an end ventilation device, which is installed on the main body structure and discharges gas or liquid in the main body structure. When the pressure in the main body structure is too large, the gas or liquid in the main body structure is discharged through the end ventilation device, thereby completing the pressure relief in the main body structure.

[0007] Preferably, the main structure includes a cooling tower body, a water distribution system and an exhaust pipe. The water distribution system is installed in the cooling tower body, and the exhaust pipe is welded to the water distribution system. Water distribution is completed through the water distribution system, and pressure relief is completed through the exhaust pipe, thereby improving the spraying performance of the water distribution system in the cooling tower body and stabilizing the water pressure of the water distribution system.

[0008] Preferably, the exhaust pipe can be installed on the water distribution system by socket and flange connection. The above arrangement improves the diversity of installation methods, has a simple structure, is economical and practical, and is relatively easy to install.

[0009] Preferably, the installation position of the exhaust pipe on the water distribution system can be adjusted to be installed at positions A, B and C according to the actual situation on site; the installation position A is 180° to the water direction of the water supply riser, B is installed at a position close to the tower inlet main pipe and the wall, and C is the end position of the pipe in the water distribution system in the cooling tower. The above three positions can all play a role in pressure discharge and stabilization, and the specific selection can be based on the actual situation on site.

[0010] Preferably, the end ventilation device includes a cover plate, a fixed short section, a fixed rod and a baffle, the cover plate and the fixed rod are fixed together by welding, the fixed rod and the baffle are fixed by welding, the fixed short section is welded to the outer wall of the exhaust pipe, and the fixed rod is slidably installed in the fixed short section; when the water pressure in the water distribution system is too high, water will be discharged to the outside through the exhaust pipe, and the end cover plate will be lifted up by the water, so that the fixed rod slides in the fixed short section, and the baffle plate contacts the fixed short section to limit the position. After the water pressure is normal, the cover plate automatically drops to its original position. During the process of the cover plate being lifted up, the cover plate can limit its lifting distance within the range of the fixed short section through the connection of the fixed rod and the baffle at the end.

[0011] Preferably, the cover plate is located at the top of the exhaust pipe; the cover plate blocks external impurities from entering the exhaust pipe and prevents external gas from flowing back into the exhaust pipe, thereby maintaining consistent air pressure inside and outside the pipe.

[0012] Compared with the prior art, the utility model has the following beneficial effects: when the pressure in the main body mechanism is too high, the gas or liquid in the main body mechanism is discharged through the end ventilation device, thereby completing the pressure relief of the main body mechanism.
