Description

Technical Field

[0001] This utility model belongs to the technical field of counter-flow mechanical ventilation cooling tower trough pipe water distribution structure, specifically relating to a counter-flow mechanical ventilation cooling tower trough pipe water distribution structure. Background Technology

[0002] The counter-flow mechanical ventilation cooling tower with a channel tube water distribution structure is a water distribution system used in cooling towers. It mainly distributes cooling water evenly to the packing layer through channels tubes. This structure utilizes gravity and the natural distribution of water flow to ensure that water forms a thin film on the surface of the packing, thereby increasing the contact area between water and air and enhancing the cooling effect. The design of the channels tubes usually takes into account flow rate, pressure loss, and water flow uniformity to achieve efficient heat exchange and energy saving. This type of water distribution structure is widely used in industrial cooling and air conditioning systems.

[0003] Cooling towers are now an indispensable piece of equipment for many large shopping malls, factories, and power plants. As the mainstream equipment for circulating water cooling, the water distribution system of a cooling tower plays a very important role in the water cooling process. However, an unreasonable selection of the water distribution system will affect the cooling effect of the entire tower. Utility Model Content

[0004] The purpose of this utility model is to provide a counter-flow mechanical ventilation cooling tower with a trough-type water distribution structure to solve the problem mentioned in the background art. Cooling towers are now an indispensable piece of equipment for many large shopping malls, factories and power plants. As the mainstream equipment for circulating water cooling, the water distribution system of the cooling tower plays a very important role in the water cooling process. However, an unreasonable selection of the water distribution system will affect the cooling effect of the entire tower.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a counter-flow mechanical ventilation cooling tower trough-pipe water distribution structure, including a cooling tower body, a cooling tower water trough installed at the right end of the cooling tower body, the cooling tower water trough discharging gas through exhaust pipes at both ends of the upper end, a maintenance manhole provided at the upper end of the cooling tower water trough, a pre-embedded sleeve provided at the left end of the cooling tower water trough, a water distribution branch pipe installed at the left end of the pre-embedded sleeve, a drain valve provided at the lower end of the cooling tower water trough, a pipe A installed at the lower end of the drain valve, a pipe B provided at the right end of the pipe A, and an arc-shaped filter screen fixed inside the pipe A.

[0006] Preferably, a motor is installed at the upper end of the cooling tower body on the right side, and the motor drives a reducer installed at the left end to work. A blade is installed at the upper end of the reducer.

[0007] Preferably, an air outlet is provided at the upper end of the cooling tower body, and the blades and reducer are installed inside the air outlet.

[0008] Preferably, a support base is fixed at the lower end of the cooling tower water tank.

[0009] Preferably, the cooling tower water tank is located on the outer side of the cooling tower body, and the cooling tower water tank reduces the resistance and static pressure inside the cooling tower body.

[0010] Preferably, the cooling tower water tank is connected to the water distribution branch pipe through a pre-embedded sleeve, which reduces the number of connecting parts, and the exhaust pipe makes the pressure inside the cooling tower water tank the same as the outside pressure.

[0011] Preferably, the drain valve can discharge sludge and impurities inside the cooling tower water tank, and the maintenance manhole is provided for maintenance personnel to maintain and repair the cooling tower water tank.

[0012] Preferably, the sludge discharged by the drain valve flows to the external location via pipe A, and the arc-shaped filter screen isolates impurities in the sludge. At the same time, the arc-shaped filter screen guides the impurities to flow towards pipe B under the action of sludge pressure through its arc-shaped structure.

[0013] Compared with the prior art, this utility model provides a counter-flow mechanical ventilation cooling tower with a trough-tube water distribution structure, which has the following advantages:

[0014] 1. This device involves a trough-pipe water distribution system. While primarily suitable for applications with good water quality, our improvements make it applicable to the vast majority of situations. Its main advantages include more uniform water distribution, reduced static pressure within the tower, fewer installation components, and lower risk of damage and maintenance costs. Compared to ordinary pipe-type water distribution, this method replaces the main pipe inside the tower with an external water trough, reducing resistance and static pressure within the tower. Water flows more stably in the trough than in a pipe, as pipes often require diameter changes within the tower, altering both the pipe's cross-sectional area and water velocity, leading to unstable flow rates that can affect the overall stability of the distribution system. In contrast, the trough-pipe system uses an external water trough for the main pipe, with branch pipes directly connected to it, reducing the number of connecting fittings, lowering the risk of component damage, and reducing maintenance costs.

[0015] 2. Pipe A is installed at the lower end of the drain valve. The sewage discharged from the drain valve flows to the outer position through pipe A. An arc-shaped filter screen is fixed on the inner side of pipe A. The arc-shaped filter screen isolates impurities in the sewage. Under the impact of water pressure and the arc-shaped structure of the filter screen, the impurities are guided to the inner position of pipe B. Finally, the impurities in the sewage are discharged to the outer position through pipe B, while pipe A transports the sewage to the subsequent purification equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The utility model provides, for example Figure 1-5 The diagram shows a counter-flow mechanical ventilation cooling tower with a trough-pipe water distribution structure, including a cooling tower body 7, a cooling tower water trough 1 installed at the right end of the cooling tower body 7, the cooling tower water trough 1 discharging gas through exhaust pipes 2 at both ends of the upper end, a maintenance manhole 4 provided at the upper end of the cooling tower water trough 1, a pre-embedded sleeve 5 provided at the left end of the cooling tower water trough 1, a water distribution branch pipe 6 installed at the left end of the pre-embedded sleeve 5, a drain valve 3 provided at the lower end of the cooling tower water trough 1, a pipe A13 installed at the lower end of the drain valve 3, a pipe B14 provided at the right end of the pipe A13, and an arc-shaped filter screen 15 fixed inside the pipe A13.

[0026] The circulating water requiring cooling flows through the water tank, where its flow rate is reduced. At a stable flow rate, it is evenly sprayed into the cooling tower through the pre-embedded sleeve 5 and water distribution branch pipe 6, achieving a good spraying effect. The exhaust pipe 2 at the top of the water tank can maintain the same air pressure inside the water tank as outside, playing a role in stabilizing the water pressure inside the water tank. The maintenance manhole 4 allows for timely maintenance in case of problems during the operation of the cooling tower. The drain valve 3 can promptly discharge sludge and impurities from the water tank, ensuring the cleanliness of the water quality and the stability of the water volume.

[0027] like Figure 1 and Figure 2As shown, a motor 9 is installed at the upper right side of the cooling tower body 7. The motor 9 drives a reducer 11 installed at the left side. A blade 8 is installed at the upper end of the reducer 11. An air outlet 10 is provided at the upper end of the cooling tower body 7. The blade 8 and the reducer 11 are installed inside the air outlet 10. A support base 12 is fixed at the lower end of the cooling tower water tank 1. The cooling tower water tank 1 is located on the outer side of the cooling tower body 7. The cooling tower water tank 1 reduces the resistance and static pressure inside the cooling tower body 7.

[0028] Moving the main pipe inside the tower to the outside and replacing it with an external water tank reduces resistance and static pressure inside the tower, resulting in more uniform airflow and better heat exchange performance. Compared to pipes, the water tank has a larger cross-sectional area and a more stable water flow rate, which in turn makes the entire water distribution system more stable and achieves better spraying effect. The water tank is directly connected to the branch pipes inside the tower, making it more stable and reliable. The number of connecting parts is reduced, lowering the risk of damage and reducing subsequent maintenance costs.

[0029] like Figure 4 and Figure 5 As shown, the cooling tower water tank 1 is connected to the water distribution branch pipe 6 through the pre-embedded sleeve 5, which reduces the number of connecting parts. The exhaust pipe 2 makes the pressure inside the cooling tower water tank 1 the same as the outside. The drain valve 3 can discharge the sludge and impurities inside the cooling tower water tank 1. The maintenance manhole 4 is used by maintenance personnel to maintain and repair the cooling tower water tank 1. The sludge discharged by the drain valve 3 flows to the external location through the pipe A13. The arc-shaped filter screen 15 isolates the impurities in the sludge. At the same time, the arc-shaped filter screen 15 guides the impurities to flow to the pipe B14 under the action of the sludge pressure through the arc structure.

[0030] The sewage discharged from the drain valve 3 flows to the outer position through the pipe A13. An arc-shaped filter screen 15 is fixed on the inner position of the pipe A13. The arc-shaped filter screen 15 isolates impurities in the sewage and guides the impurities to the inner position of the pipe B14 through the arc structure of the arc-shaped filter screen 15 and the impact of water pressure.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
