| 摘 要： | 滴头堵塞是滴灌系统运行中的一大难题,对于高含沙水来说更为突出.针对多泥沙河道取水时引水必将引沙的现状,在分析了我国主要河道水沙分布特点的基础上,结合天然河道"水小沙少、水大沙多"的特点,提出了明暗结合式取水模式,采用枯水期明引与洪水期暗引相结合的方式,为解决多泥沙河道取水提供了新思路.利用研发的小型移动式过滤设备、简易过滤装置、可拆式灌水器等高含沙水滴灌专用设备进行组装配套,形成了适合于高含沙水的滴灌系统,使系统配套性能和运行效率均得以提高.与现有滴灌系统相比,系统造价大幅降低,堵塞率控制在5%以内,为解决高含沙水滴灌系统的易堵塞、投资高的难题提供了新途径.

| Abstract: | Emitter-clogging is a puzzle in drip irrigation systems,especially with high sediment water resources.Based on analyzing the rule of water and sand distribution in nature river,a mode of open and hidden water intake from river was put forward,which can intake water and control sediment in flood and dry seasons.It provides a new way of water intake from a high sediment-laden river.Key equipments and products of drip irrigation systems were developed,such as movable filters,simple filters and renewable emitte... |
