Rain energy collecting and utilizing system for rainwater at roof of high-rise building

Abstract

The invention discloses a rain energy collecting and utilizing system for rainwater at a roof of a high-rise building. The rain energy collecting and utilizing system is characterized by structurally comprising a water collecting slope of a building roof, wherein the bottom of the water collecting slope (1) is connected with a simple physical and chemical purification device (3) through a rainwater pipe (2), the simple physical and chemical purification device (3) is communicated with a water storage tank (5) through a connecting hole (4), the bottom of the water storage tank (5) is connected with a water consumption pipe (6), a toilet flushing water consumption pipe (10) of each user unit is respectively connected to the water consumption pipe (6), and the upper part of the water consumption pipe (6) is also connected with a traditional water supply pipe (9). The rain energy collecting and utilizing system has the advantages that the rainwater is accumulated, meanwhile, the rain energy of the rainwater at the top of the high-rise building is accumulated, the energy source is fully utilized, in addition, the classification utilization of water quality is realized, the rainwater is used for flushing toilets, a purification system is simplified, in addition, matched pipe networks and facilities for rainwater collection are reduced in a mode of both production and use by self, meanwhile, the contribution to rain blockage and accumulation for urban flood control from the source is made, and high popularization values are realized.

Description

technical field [0001] The invention relates to high-efficiency utilization of water resources, especially rainwater resource utilization technology, and specifically refers to a high-rise building rainwater and rain energy collection and utilization and distributed flood control and storage system. Background technique [0002] China is a country seriously short of water resources. The per capita water resources are only 1 / 4 of the world's per capita, and the water resources are unevenly distributed in time and space. Water-scarce areas cannot just wait for cross-basin water transfers, and should fully expand and recycle local water resources. Among them, urban rainwater is a water resource that has not been fully utilized at present. Incomplete utilization of rainwater resources is not only a waste of water resources, but also a waste of water. Energy resources are wasted, and the problem of urban flood control caused by heavy rain cannot be ignored. At present, my countr...
