Water collection system of high-level water collection tower

Abstract

The invention relates to a water collection system of a high-level water collection tower. The system comprises a water collection device centering on a central axis of the high-level water collection tower and including three circular distribution areas sequentially outwards: an inner area, a middle area and an outer area; the water collection device comprises a plurality of water collection sloping boards, all the boards are distributed in the inner area, middle area and outer area, maximum length of those boards distributed in the inner area is L1, maximum length of those boards distributed in the middle area is L2, and maximum length of those boards distributed in the outer area is L3, wherein L1<L2 or L1<L3. The system makes full use of cooling capacities of various areas, lowering effluent temperature of a cooling tower; the system can also save the running cost of the high-level water collection tower, lowering energy consumption.

Description

technical field [0001] The invention relates to the technical field of high-level water collection towers, in particular to a water collection system for high-level water collection towers. Background technique [0002] The high-level water collection tower is one of the important thermal equipment in large-scale power plants, and its operating performance has a great influence on the safety and economy of the power plant. The water collection sloping plate of the water collection system of the traditional high-level water collection tower is uniformly arranged, and the water distribution distribution and the aerodynamic field are not properly matched during operation. The larger the regional air flow rate, the smaller the air flow rate near the outer area, which causes the problem of insufficient air in the periphery, which affects the cooling effect of the peripheral circulating water, and eventually leads to uneven cooling and low cooling efficiency of the high-level wate...

AI Technical Summary

Problems solved by technology

The water collection sloping plate of the water collection system of the traditional high-level water collection tower is uniformly arranged, and the water distribution distribution and the aerodynamic field are not properly matched during operation. The larger the regional air flow rate, the smaller the air flow rate closer to the outer area, which causes the problem of insufficient air in the periphery, which affects the cooling effect of the peripheral circulating water, and finally leads to uneven cooling and low cooling efficiency of the high-level water collection tower.
