Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a water distribution device for a cooling tower group and a cooling tower group. Background Art

[0002] In the existing cooling tower group, the water to be treated is distributed to each cooling tower in the cooling tower group through a unilateral branch pipeline or a bilateral branch pipeline. The existing cooling tower group has the following problems: due to the difference in the water inlet pressure between the proximal branch and the distal branch of the branch pipeline, the amount of water to be treated flowing into each cooling tower is different. The cooling tower with more water to be treated has an overloaded treatment capacity, while the cooling tower with less water to be treated is severely short of water, wasting the cooling capacity of the cooling tower, thus resulting in a poor overall cooling effect of the cooling tower group. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a water distribution device for a cooling tower group. By using this water distribution device, the water to be treated can be evenly distributed to each cooling tower in the cooling tower group.

[0004] To solve the above technical problem, a water distribution device for a cooling tower group provided by the utility model includes an annular pipeline. The annular pipeline includes a pair of water distribution main pipes spaced apart in the horizontal direction. The water distribution main pipes are horizontally arranged. The two ends of one water distribution main pipe are connected to the two ends of the other water distribution main pipe through a connecting pipe. A plurality of horizontally arranged water distribution branch pipes are arranged at intervals on the water distribution main pipes. An inlet branch pipe is arranged in the middle of one connecting pipe.

[0005] Further preferably, a flow sensor is connected in series on the water distribution branch pipe. An automatic valve is connected in series on the pipeline between the flow sensor and the water distribution main pipe. The actuator of the automatic valve and the flow sensor are respectively connected to a controller. The controller obtains the water flow rate of each branch pipeline through the flow sensor, and automatically controls the opening degree of the automatic valve to control the water flow rate of the branch pipeline, so that the water flow rate of each branch pipeline is the same.

[0006] Further preferably, the automatic valve is an electric ball valve.

[0007] A cooling tower group includes the above-mentioned water distribution device, and also includes cooling towers with the same number and corresponding positions as the water distribution branch pipes on the water distribution main pipes. Two water inlets are arranged on the cooling towers, and the two water inlets are respectively connected to a pair of relatively distributed water distribution branch pipes.

[0008] Advantages of the present utility model: Since the water pressure flowing through each water distribution branch pipe is the same, the water flow rate flowing through each water distribution branch pipe is also the same. By using the said water distribution device, the water to be treated can be evenly distributed to each cooling tower in the cooling tower group, improving the overall cooling effect of the cooling tower group and reducing the energy consumption of the cooling towers; by using the water distribution device of the present novel type, the water to be treated can be evenly distributed to each cooling tower in the cooling tower group.
