Energy-saving environmentally-friendly roof rainwater recycling device

Abstract

The invention discloses an energy-saving environmentally-friendly roof rainwater recycling device. The device mainly comprises an abandon flow device, a water storage box and a water collection tank,a filter cover is arranged on the water collection tank, and the water collection tank is communicated with the abandon flow device through a water inlet pipe; the abandon flow device is divided intoa diversion chamber and an abandon flow chamber which are vertically communicated through an inverted-cone-shaped funnel, the diversion chamber is provided with a basket type grating, a second water inlet and a water outlet, the water outlet is communicated with the water storage box, an abandon flow pipe is connected to the lower portion of the abandon flow chamber through an abandon flow openingand communicated with a municipal sewage pipe, a water stop mechanism is arranged between the diversion chamber and the abandon flow chamber, and the water stop mechanism controls discharge of initial rainwater; the water storage box is arranged to be a filter tank and a clean water tank through a partition plate, a through hole is formed in the partition plate, the filter tank is internally provided with a filter plate and a disinfection device, multiple water diversion pipes are connected to the clean water tank, and a water device is connected to the water diversion pipes. Accordingly, thestructure is simple, energy conservation and environmental protection are achieved, rainwater sterilization and disinfection are facilitated, and the recovered water quality is high.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to an energy-saving and environment-friendly roof rainwater recycling device. Background technique [0002] my country is a country with severe drought and one of the countries with the poorest per capita water resources in the world. However, my country's water consumption is the largest country in the world. Broadening sources of income and reducing expenditure is an effective way to alleviate the pressure on urban water use. Rainwater is a natural resource. Rainwater recycling can not only reduce the pressure on the municipal rainwater pipe network and alleviate urban flood disasters, but also effectively reduce the pressure on urban water use. In the early stage of rainfall, the rainwater dissolves a large amount of polluting gases such as acid gas, vehicle exhaust, and factory exhaust gas in the air, making the early rainwater highly pollute...

Problems solved by technology

Among the existing roof rainwater recovery and utilization devices, some have the function of discarding water, but most of them are controlled by solenoid valves, which require electricity, high manufacturing cost, complicated structure, and difficult to maintain

The disinfection device in the water tank needs to replace the disinfection potion regularly, which increases manual labor; or after using the ultraviolet disinfection lamp for a long time, the surface of the disinfection lamp is covered with impurities, and the disinfection effect is low
