The specific embodiment
Fig. 1 is existing following spray cooling tower trickle cell structure, as shown in the figure, directly rush in the cooling tower trickle chamber 7 behind the backwater 4 process trickle valves 5 in the return pipe, because current lack buffering, flow velocity is too fast, and a part of water is directly rushed in filler 9, remainder water is acutely bounce-back on drip water plate 8, strike after the bounce-back cover plate 6 be distributed to rapidly again cooling tower trickle chamber 7 around, cause the zone line water yield few, and the many situations of the peripheral regions water yield.Backwater 4 is gone into pond 10 with the cold air heat exchange is laggard in filler 9, because water distribution is inhomogeneous, and the many zones of the water yield are because flow area institute existence water blockoff phenomenon, the result causes the peripheral regions water yield many and flow velocity is slow, and the zone line water yield is few and flow velocity is fast, backwater heat exchange weak effect, the position of water bounce-back bump causes partial cover plate 6 to wash out.Filler over against trickle valve 5 is impacted by the backwater that directly sweeps away through the trickle hole, because water speed is too fast, often causes filler 9 to be washed out, and broken filler fragment can cause badly damaged to water pump and other watering equipments.
Referring to Fig. 2, Fig. 3, the utility model comprises bucket shape body 1 and base plate 2, and bucket shape body 1 forms hydroecium with base plate 2; Described bucket shape body 1 top has through hole 11.
Referring to Fig. 4, offer several trickle holes 21 on the described base plate 2, several flow distribution plates 3 are set on the base plate; Differing in size of flow distribution plate 3, distance does not wait between the flow distribution plate 3.Wherein flow distribution plate 31 is different with flow distribution plate 32 sizes, because spacing is bigger, and resistance to water-flow is less, shunts the main channel thereby form between flow distribution plate 31 and the flow distribution plate 32; Between flow distribution plate 31 and the flow distribution plate 31, between flow distribution plate 32 and the flow distribution plate 32 because spacing is less, and resistance to water-flow is bigger, thereby form the shunting subchannel.Under the effect of flow distribution plate 31,32, backwater 4 at first flows along the shunting main channel, and be diverted to subchannel again and flow, thus the shunting action of playing.
