Problems solved by technology

However, at the current stage, the above-mentioned excess water head has not been effectively utilized, and the lower floors of many partitions in the design even use pressure reducing valves for decompression
[0006] There is also a system that utilizes water pressure energy to generate electricity. For example, on October 22, 2014, the Chinese patent with the publication number CN203892106U discloses a power generation system that utilizes water pressure energy recovery. speed, generator and valve; its connection relationship is: the inlet of the water turbine is connected with the outlet of the high-pressure water supply pipeline through a valve, and the outlet of the water turbine is connected with the inlet of the low-pressure water pipeline through a valve; The shaft is connected to the generator through a reducer. Although it can reduce the energy consumption of the building in its entire life cycle and improve the economy and energy saving of the building, it also has the following disadvantages: (1) The above invention does not specifically combine the system layering of high-rise buildings Layout; (2) Only the power generation system is described, and the whereabouts after energy recovery is not included; (3) The water turbine, governor, and generator in the power generation system are separated from each other, which takes up a lot of space and costs high (4) Does not Combining with high-rise buildings, effectively explain the selection of generator parameters on each floor

Abstract

The invention relates to an energy recovery system for secondary boosting in high-rise building water supply. Currently, recycling and regenerating of surplus mechanical energy of water bodies during secondary boosting in high-rise building water supply do not exist. The energy recovery system is characterized in that the energy recovery system comprises Q water supply secondary boosting energy collection system zones, wherein the Q is larger than or equal to 1; any water supply secondary boosting energy collection system zone comprises a water supply boosting pump, a vertical water supply pipe and water supply systems of Mth-Nth floors, wherein the water supply systems of the Mth-Nth floors are sequentially connected to the vertical water supply pipe from bottom to top; the water supply secondary boosting energy collection system zones are in one-to-one correspondence with building water supply secondary boosting system zones; the water supply system of the Mth floor comprises a first transverse water supply pipe, a first valve, a pipeline-type waterflow power generator, a first water distribution faucet, an output wire and a storage battery. The energy recovery system has the advantages of energy conservation, consumption reduction, environment protection, simplicity in construction and low cost.

Description

technical field [0001] The invention belongs to the field of energy recovery and regeneration, and relates to a water resource energy recovery system, in particular to a high-rise building water supply secondary pressurization energy recovery system. Background technique [0002] In recent years, the rapid development of my country's real estate industry and the soaring land prices in urban centers have led to explosive growth of new high-rise buildings with large floor area ratios; on the other hand, the concept of sustainable development has become increasingly popular, making green buildings a new trend in architectural design trend. [0003] In the field of water supply and drainage, many resource regeneration methods have been formed, such as the reuse of reclaimed water, rainwater collection and reuse, and the application of heat pump systems, with obvious energy-saving effects. However, in the secondary pressurization process of water supply for high-rise buildings, t...
