Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The water distribution device suitable for the countercurrent cooling tower as shown in fig. 1 to 3 comprises a shunt pipe 1, wherein the bottom of the shunt pipe 1 is communicated with a water inlet pipe (not shown in the figure), two sides of the shunt pipe are connected with water distribution pipes 2, the water distribution pipes 2 comprise a uniform flow pipe 21, and a sprinkler pipe 22 is arranged outside the uniform flow pipe 21; one end of the flow equalizing pipe 21 is communicated with the flow dividing pipe 1, the other end is closed, and a plurality of flow equalizing holes 211 are formed in the top; the sprinkler pipe 22 is sleeved outside the uniform flow pipe 21, two ends of the sprinkler pipe are closed, the sprinkler holes 221 are fully distributed within the range of 150 degrees along the length direction and the bottom symmetry of the sprinkler pipe 22, and the distance d between every two sprinkler holes 221 is 10-30mm.
Working principle and working process:
The water distribution pipes 2 are horizontally arranged on the split pipes 1 of the cooling towers, each cooling tower is provided with a plurality of water distribution pipes 2, each water distribution pipe 2 is arranged in parallel and equidistantly, and the distance between the two water distribution pipes 2 is determined after calculation according to the water quantity and the geometric dimension of the cooling tower. The principle of calculation is to ensure that the water flow can cover substantially all of the area of the packing 3 in the range of 10% -100% of the water volume, allowing the water flow to cross but not allowing the blank area to appear. Referring to fig. 4 and 4, when the cooling tower is in operation, water flows into the diversion pipe 1 through the water inlet pipe of the cooling tower, then flows into the uniform flow pipe 21 through the diversion pipe 1, is uniformly distributed through the uniform flow holes 221, then flows into the sprinkling pipe 22, and uniformly sprinkles on the filler 3 through the sprinkling holes 221. When the water quantity is large, the water flows between two adjacent water distribution pipes 2 are overlapped in a crossing way, when the water flows are gradually reduced, the jet speed of the water flows is reduced, the jet distance is gradually shortened under the influence of a free falling law, and finally, the water flows are separated. The minimum water jet speed involved should be able to ensure that the water flow coverage areas between two adjacent water distribution pipes 2 are just connected, and a larger blank area should not appear in the middle.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
