Roof rainwater collecting and purifying system
The invention discloses a roof rainwater collecting and purifying system. In an initial stage, rainwater is retained in an emptying pipe at the lower part of a collecting pipe and is discharged after rain stops, the rainwater is filtered by a stainless steel screen after the initial rainfall stage, and impurities in the rainwater are deposited to the bottom of the hydraulic cyclone separation device under the action of spiral flow. And after the impurities at the bottom are accumulated to a certain degree, the piezoelectric actuator opens the bottom valve, and the impurities are discharged. And an upper electromagnetic valve and a lower electromagnetic valve are arranged on a pipeline for connecting the sterilizing device and the high-level water storage tank. The upper electromagnetic valve is used for automatically feeding water and automatically closing a pipeline after the water level of the water tank meets requirements; when the lower electromagnetic valve detects that the water level in the disinfection device is low, the pipeline is closed so as to deal with damage to the pipeline and the device caused by continuous working of the upper electromagnetic valve when the rainwater supply is insufficient, and finally the outlet water is used as urban miscellaneous water. The roof rainwater is collected, treated and utilized, the purpose of rainwater resource utilization is achieved, and the roof rainwater recycling system has a feasible practical value and a wide application prospect.
本发明公开了一种屋面雨水收集净化系统，初期雨水滞留在收集管下部的排空管待雨停后排放，降雨初期过后雨水经过不锈钢筛网过滤，在螺旋流的作用下，雨水中的杂质沉积到水力旋流分离装置的底部。待底部杂质积累到一定程度后，压电驱动器将底部阀门打开，排出杂质。在连接消毒装置和高位储水箱的管路上安装上、下电磁阀。上电磁阀用于自动上水和水箱水位满足要求后自动关闭管路；下电磁阀检测到消毒装置内水位较低时关闭管路，以应对雨水供应不足时上电磁阀继续工作对管路、装置造成的危害，最终出水用于城市杂用水。本发明对屋面雨水进行收集、处理和利用，实现雨水资源化利用的目的，具有切实可行的实用价值和广泛的应用前景。
