Abstract

Disclosed are a secondary-pressurizing energy-saving water-supply system for a high-rise building and an energy-saving water supply method. The secondary-pressurizing energy-saving water-supply system for the high-rise building comprises a valve, a main water inlet pipe, a mainstream flow sensor, a mainstream pressure sensor, a tee joint, an ejector, an auxiliary pressure sensor, a water pump, a first one-way valve, a control box with a controller, a virtual high-level water tank, a second one-way valve, a first electric adjusting valve, a second electric adjusting valve, an auxiliary flow sensor, a surge tank and a user pipeline which are connected mutually. The structure of the ejector is optimized, the technique of the virtual high-level water-tank is adopted, and the energy-saving water supply method is free in energy input, so that the rate of energy recovery of water in a municipal water pipe network is greatly increased, power consumption of the main pump is reduced by 10-35%, the energy is saved, the stability and security is improved and energy conservation and environmental friendliness are achieved significantly.

Description

technical field

[0001] The invention belongs to the field of high-rise water supply, in particular to an energy-saving high-rise water supply system for secondary pressurization and an energy-saving water supply method thereof. Background technique

[0002] At present, there are more and more high-rise buildings all over the world, and the demand for secondary water supply is also more and more extensive. At this stage, the secondary pressurized water supply method with advanced technology is the box-type non-negative pressure water supply system. The characteristic of this water supply system is that the municipal water is discharged into the water tank first, and then through a three-way flow controller or flow matching. The device supplies water to the secondary pressurized main pump. To achieve pressure matching, a small pump or auxiliary pump is usually required between the tank and the tee to bring the water in the tank to municipal water pressure. The disadvantage o...
