An integrated air-medium energy return system for high-rise water supply and drainage based on air energy storage

Abstract

The invention relates to a high-rise water supply and drainage integrated gas medium energy return-flow system based on air energy storage. The high-rise water supply and drainage integrated gas medium energy return-flow system comprises an energy collecting module, a torque increasing transmission module and an energy return-flow module. The energy collecting module is composed of a gas guide-out pipe, a sewer line and a pelton turbine; the torque increasing transmission module comprises a reducer and a crankshaft and connecting rod mechanism, a power input gear of the reducer and the pelton turbine are coaxial, and a power output gear of the reducer is installed on a crankshaft of the crankshaft and connecting rod mechanism; and the energy return-flow module comprises a piston, an inflator, a gas temporary storage tank and a secondary water supply pressure tank, the piston is connected to the end of the crankshaft, and a gas outlet of the inflator is communicated to the gas temporary storage tank in a one-way manner to be then communicated to the secondary water supply pressure tank in a one-way manner to be finally communicated to the gas guide-out pipe in a one-way manner. According to the high-rise water supply and drainage integrated gas medium energy return-flow system, potential energy of high-rise waste water is collected and is stored in a gas storage device in the manner of high-pressure gas potential energy and is used for existing residential area secondary water supply systems, and therefore part of water supply energy flows back to assist in water supply, and energy consumption of high-rise water supply is reduced.

Description

technical field [0001] The invention relates to a fluid-driven energy recovery device, in particular to an integrated air-medium energy return system for water supply and drainage of high-rise buildings based on air energy storage. Background technique [0002] Since entering the 21st century, energy and the environment have had an increasing impact on human life and social development. Residential buildings are increasingly high-rise, which puts forward higher requirements for the necessities in people's daily life: running water. On the one hand, the excessively high floors have caused most residential areas to build secondary water supply systems to meet the water pressure requirements of water supply; on the other hand, the energy used to supply tap water to high-rise buildings has also greatly increased. Correspondingly, the energy loss accompanying the wastewater discharge of residents is more serious. [0003] For this part of energy, current related research focuse...
