High-rise building auxiliary water supply system capable of utilizing building drainage energy

Abstract

A high-rise building auxiliary water supply system capable of utilizing building drainage energy comprises a low-region water tank, a middle-region water tank and a high-region water tank. The special points are that the high-rise building auxiliary water supply system also comprises a high-region drainage vertical pipe, a middle-low-region drainage vertical pipe and a pressure water supply tank, wherein the pressure water supply tank is divided into an inner cavity and an outer cavity by a diaphragm; a sanitary wastewater buffering box is arranged between the high-region drainage vertical pipe and the middle-low-region drainage vertical pipe; the sanitary wastewater buffering box is higher than the middle-region water tank; a drainage pipe is arranged at the bottom of the sanitary wastewater buffering box; the drainage pipe is communicated with the inner cavity of the pressure water supply tank through an electromagnetic three-way valve; the low-region water tank is communicated with an inlet of the outer cavity of the pressure water supply tank; an outlet of the outer cavity of the pressure water supply tank is communicated with the middle-region water tank; and the pressure water supply tank is lower than the low-region water tank. The high-rise building auxiliary water supply system utilizes an elevating head of drainage of sanitary sewage of users in the high region of the high-rise building as power of water supply for users in the middle region and effectively reduces energy consumption of water supply on the premise of not influencing normal operation of the original water supply and drainage system.

Description

technical field [0001] The invention relates to high-rise building water supply and drainage technology, in particular to an auxiliary water supply system based on high-rise building drainage that can save high-rise building water supply energy consumption, and belongs to the technical field of building water supply and drainage. Background technique [0002] With the increasing energy crisis, energy conservation and emission reduction has now become a hot topic of common concern all over the world. Taking China as an example, building energy consumption accounts for about one-third of the total energy consumption of the society. Building energy consumption has become the three "big energy consumers" of energy consumption in parallel with industrial energy consumption and transportation energy consumption. are getting more and more attention. [0003] The series water supply and parallel water supply with water pumps and water tanks are the water supply methods often used i...

Problems solved by technology

[0005] With regard to the reuse of drainage energy in high-rise buildings, it has been proposed that this part of the energy be used for power generation. However, due to the high potential energy of high-rise drainage, it is necessary to take measures to reduce the flow rate of drainage, such as increasing the roughness of the inner wall of the pipe, and the upper separation of the riser. There are certain difficulties in implementing methods such as setting "B bends" at a certain distance
