Description

Technical Field

[0001] This utility model relates to the field of counter-flow cooling towers, specifically to a counter-flow cooling tower with uniform water distribution. Background Technology

[0002] A counter-flow cooling tower is a type of cooling tower where water flows from top to bottom within the packing material, while air flows from bottom to top, creating a reverse flow. The cooling tower operates in three stages: 1. The water distributor delivers water to the top of the packing material, where the higher water temperature allows for continued heat transfer to the air; 2. The water at the top of the packing material exchanges heat with the hot air at the bottom, a process known as the counter-flow section; 3. When the packing material reaches the bottom collection tank, the hot water is cooled and becomes cold water. Counter-flow cooling towers are more efficient than cross-flow towers. Advantages of counter-flow cooling towers include: 1. Simple design, smooth water distribution system, minimal requirements for the water distribution process, and resistance to clogging. The use of water-spraying packing material prevents aging and moisture backflow. Anti-freezing measures are easily implemented in low-temperature environments. Multiple cooling towers can be designed for simultaneous operation; 2. Simple operation. Production costs are controllable, and it is typically used in large-scale cooling water circulation systems.

[0003] The existing technology has the following problems:

[0004] In existing technologies, counterflow cooling towers are generally large in size, and the water distribution pipes and packing inside the tower need to be maintained and replaced regularly. Therefore, it is necessary to design a counterflow cooling tower that is easy to maintain and has uniform water distribution. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a counter-flow cooling tower with uniform water distribution to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A counter-flow cooling tower with uniform water distribution includes a base, a main frame assembly fixedly connected to the top of the base, a lower shell assembly and an upper shell assembly disposed inside the main frame assembly, an exhaust assembly disposed at the top of the main frame assembly, a water distribution pipe and packing disposed on the inner wall of the main frame assembly, and several nozzles disposed at equal intervals at the bottom of the water distribution pipe.

[0008] The water distribution pipe runs through the main frame assembly and is arranged in a vortex shape inside. By arranging the water distribution pipe in a vortex shape inside and using it in conjunction with several nozzles that are equidistantly arranged, the effect of even water distribution can be achieved.

[0009] The main frame assembly includes a base frame, the outer wall of which has two lower operating slots, a central connecting ring plate fixedly connected to the top of the base frame, and several upper branch brackets arranged in a ring around the top of the central connecting ring plate, with an upper cover plate fixedly connected to the top of each upper branch bracket.

[0010] The lower shell assembly includes a blocking plate movably mounted on the outer wall of the base frame and an outer support plate fixedly mounted on the outer wall of the base frame. Several drive motors are mounted on the top of the outer support plate, and the output shafts of the drive motors are fixedly connected to a drive disc via a coupling. By setting up the lower shell assembly and using it in conjunction with the main frame assembly, in use, by starting and controlling the drive motors, the drive discs are rotated, thereby driving the blocking plate to rotate along both sides of the base frame, so as to open and close the lower operating slot for the purpose of maintaining and replacing the water distribution pipes, nozzles and packing inside the tower.

[0011] The upper housing assembly includes an upper support fixedly mounted on top of the upper distribution support and an upper housing movably mounted on the outer wall of the upper distribution support. The upper housing has pivot pins on both sides of its upper end, and its upper end is movably connected to the upper distribution support via these pivot pins. A pull ring is fixedly connected to the outer wall of the upper housing. Several motor mounts are fixedly connected to the top of the upper support. A winding motor is fixedly connected to the inner wall of each motor mount. The output shaft of the winding motor is fixedly connected to a winding shaft via a coupling. A pull rope is fixedly connected to the outer wall of the winding shaft, and one end of the pull rope is fixedly connected to the outer wall of the pull ring. By configuring and using the upper housing assembly, the winding motor is started and controlled, causing the winding shaft to rotate and wind up the pull rope, thereby pulling the upper housing upwards. This causes the upper housing to rotate along the pivot pins, opening the upper housing and allowing maintenance and replacement of the water distribution pipes, nozzles, and packing inside the tower from above the main frame assembly.

[0012] Preferably, there are multiple transmission discs, and the outer walls of the multiple transmission discs are provided with rubber layers, and the outer walls of the transmission discs are fitted and connected to the outer walls of the blocking plate.

[0013] Preferably, the blocking plate includes an outer blocking plate and an inner blocking plate. The inner wall of the outer blocking plate is fitted and connected to the outer wall of the base frame, and the outer wall of the inner blocking plate is fitted and connected to the inner wall of the base frame. A connecting support plate is fixedly connected between the outer blocking plate and the inner blocking plate.

[0014] Preferably, the exhaust assembly includes a fan fixedly mounted on the upper cover plate, the upper cover plate has two exhaust holes on its top, and the fan is positioned above the exhaust holes.

[0015] Preferably, the exhaust assembly further includes an upper support fixed to the upper cover plate, and an exhaust elbow is fixedly connected to the top of the upper support.

[0016] Preferably, there are two exhaust bends, and the air inlet of the exhaust bends is located above the fan.

[0017] Preferably, the exhaust bend is a rigid exhaust bend, and a drain hole is provided at the bottom of the lower bend of the exhaust bend. With the exhaust assembly, when the fan is started to draw air upward from inside the tower, the air that has exchanged with the hot water in the water distribution pipe contains a lot of water vapor. The drawn air can be discharged outward along the exhaust bend, and the air will liquefy upon cooling in the exhaust bend and fall through the drain hole, preventing the air from falling into the fan and affecting the service life of the fan.

[0018] Preferably, the bottom of the base has several air inlet slots, and the bottom of the base is fixedly connected to a foot pad.

[0019] The beneficial effects of this utility model are as follows: 1. This counter-flow cooling tower with uniform water distribution, through the setting of the lower shell assembly and its use in conjunction with the main frame assembly, allows the transmission motor to be started and controlled during use. The transmission disc rotates, thereby driving the blocking plate to rotate along both sides of the base frame, thus opening and closing the lower operating slot for maintenance and replacement of the water distribution pipes, nozzles, and packing inside the tower. Through the setting of the upper shell assembly and its use in conjunction, the winding motor is started and controlled, and the winding shaft rotates to wind up the rope, thereby pulling the upper shell upward. This causes the upper shell to rotate along the pivot pin, thus opening the upper shell for maintenance and replacement of the water distribution pipes, nozzles, and packing inside the tower from above the main frame assembly.

[0020] 2. This counter-flow cooling tower with uniform water distribution, through the setting of the exhaust component, allows for the upward extraction of air from inside the tower by the fan during operation. The air that has exchanged with the hot water in the water distribution pipe contains a large amount of water vapor. The extracted air can be discharged outward along the exhaust bend, and liquefies upon encountering the cold air in the exhaust bend, falling through the drain hole and preventing the air from falling into the fan and affecting the service life of the fan.

[0043] Example 2;

[0044] Based on Embodiment 1, a preferred embodiment of the counter-flow cooling tower with uniform water distribution provided by this utility model is, for example... Figures 1-6 As shown: the exhaust assembly 4 includes a fan 402 fixedly mounted on the upper cover plate 104. The top of the upper cover plate 104 has two exhaust holes, and the fan 402 is positioned above the exhaust holes.

The water that has undergone heat exchange falls and is cooled, and can be reused. During use, the drive motor 203 is started and controlled to rotate the drive disc 204, thereby driving the blocking plate 201 to rotate along both sides of the base frame 101, so as to achieve...

[0051] In summary, with the aid of the above-mentioned technical solution of this utility model, the counter-flow cooling tower with uniform water distribution, through the setting of the lower shell assembly 2 and its cooperation with the main frame assembly 1, in use, by starting and controlling the drive motor 203, the drive disc 204 rotates, thereby driving the blocking plate 201 to rotate along both sides of the base frame 101, so as to open and close the lower operating slot 105, so as to maintain and replace the water distribution pipe 5, nozzles and packing inside the tower; through the setting of the upper shell assembly 3 and its cooperation, by starting and controlling the winding motor 305, the winding shaft rotates to wind up the rope, thereby realizing Pull the upper housing 301 upwards to rotate it along the pivot, thereby opening the upper housing 301.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
