Utilization method of fluid energy in water supply pipe network and power generation system of water supply pipe network

Abstract

The invention relates to a utilization method of the fluid energy in a water supply pipe network. A power generator is additionally arranged at a water intake of a water plant, particularly, the water intake of the water plant comprises a first branch provided with a first valve / sluice 3 and a second branch which is connected in parallel with the first branch and is sequentially provided with a second valve / sluice 52 and the power generator 6 along the flow direction, wherein the first branch is directly led to a pool of the water plant, and the second branch is also directly led to a pool or is connected to a water outlet pipeline of the first branch after passing through the second valve / sluice 52. The invention has the advantages that a power generation system is suitable for a transmission pipe network of water, gas and oil, a power generator can utilize the fluid energy to generate the power by connecting the power generation system with a pipe network mainstream pipeline in parallel, and the normal production and the use of a fluid can not be influenced although the power generator has a fault, therefore, the invention truly realizes zero discharge and zero pollution.

Description

technical field [0001] The invention relates to the transformation of the water pipe network, more specifically, to the transformation of the source water pipe network of the water plant. Background technique [0002] Under the existing technology, people use the pipe network to transport water over long distances to the water intake of the water plant. The water that reaches the water intake of the water plant carries energy, and the energy is not used and wasted directly. Take the waterworks in Shahekou District, Dalian as an example. In order to solve the problem of urban water sources, waterworks generally need to draw water from rivers or reservoirs at least 100 kilometers away. There is a drop between the highest point of the water plant and the water intake of the water plant. We know that water with a drop has energy. Taking Dalian Shahekou Water Plant as an example, it needs 400,000 tons of water per day, so the flow rate per second is 4.6 cubic meters. If the net ...

AI Technical Summary

Problems solved by technology

It can be seen that the water energy that can be reused by only one water plant in Dalian is quite considerable, and the cumulative energy that can be used in the whole country is immeasurable.
