Full-automatic rainwater separation and multi-stage utilization system for high-rise building

Abstract

The invention discloses a full-automatic rainwater separation and multi-stage utilization system for a high-rise building. The system comprises a roof, a drainage pipe, an impeller discarding device,a sewage pipe, a full-flow energy storage device, a hydraulic generator, an electric power storage device and a water storage pool. The filter screen is flush with the roof and located over the drainage pipe. The drainage pipe is connected with the impeller discarding device, the impeller discarding device is provided with a discarding pipe, the discarding pipe is connected with a sewage pipe, thefull-flow energy storage device is installed on the drainage pipe, it is guaranteed that water flow with the full pipe diameter impacts the hydro-generator and is stored in the power storage device after power generation, and rainwater flowing through the hydro-generator is finally collected into the water storage pool. Multiple functions of roof rainwater separation, rainwater energy accumulation and utilization, rainwater storage and the like are achieved, and the purposes of obtaining clean rainwater, improving the power generation efficiency and prolonging the service life of the power generation device are achieved. The whole system is small in device size, high in safety coefficient, simple in structure, low in manufacturing cost, high in economic effect and suitable for large-scalepopularization.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection and utilization, and in particular relates to a fully automatic rainwater separation and multi-stage utilization system for high-rise buildings. Background technique [0002] my country is a country with very scarce water resources. According to incomplete statistics, more than 300 of the more than 600 cities in my country are short of water, and 108 of them are seriously short of water. It will only become more and more serious. At present, water shortage has become an important factor restricting the development of cities in our country and the improvement of people's living standards. But the paradox is that there are many high-rise buildings in our country's cities, with vast roofs, which can store a lot of rainwater, but most cities directly discharge the rainwater from the roofs of high-rise buildings to the ground. If this part of rainwater can be used, it will not only greatly...

Problems solved by technology

At the same time, if the rainwater containing the initial rainwater is used for power generation, the particles in the initial rainwater will be adsorbed on the blades, and the acidic substances will corrode the power generation equipment, affecting the power generation efficiency and reducing the service life of the equipment

[0004] Chinese Patent Publication No. 205676967U, the patent name is a high-rise building rainwater recovery device, which discloses a device with a floating ball valve to realize rainwater diversion, but the device is easily damaged and fails, and the potential energy of rainwater is not utilized.

[0005] The Chinese patent publication number is 1206268008U, and the patent name is a kind of roof rainwater and rain energy comprehensive utilization system document, discloses a kind of system that realizes comprehensive utilization of rainwater through mechanisms such as rain collection device, power generation device, purification device, control device, etc. But the system contains too many electronic devices, such as the first liquid level detector, the second liquid level detector, etc., the operation of these devices needs to consume electricity, and the price of these devices is not low, but also because these electronic devices have been used for a long time Water contact, easy to damage, high later maintenance cost, low safety, at the same time, when the rain is small, the potential energy of the water flow is not concentrated, and the efficiency of the generator is low
