Embodiment Construction

[0007] After the sewage is filtered by the multi-stage filter pool, it becomes clean high-quality water and then sent to the vacuum circulating water tank. The heat turns into steam in the bin, is recovered by the steam recovery bin, and becomes supercritical liquid after passing through the medium-pressure steam bin, high-pressure steam bin, and supercritical pressure cylinder to drive the steam turbine to generate electricity. The low-temperature and low-pressure water vapor discharged after power generation is sent to the vacuum circulation water tank by the air extractor. The water vapor that is not turned into water is recovered by the steam recovery chamber for power generation.

[0008] The condensed water generated during the layer-by-layer compression and heating process is transferred from the high-pressure steam chamber→medium-pressure steam chamber→steam recovery chamber→the heat exchanger at the bottom of the vacuum circulation water chamber; the heat becomes stea...

Abstract

The invention discloses a process flow which has lower power generation cost than thermal power generation and utilizes the thermal energy of sewage to generate electricity and supply water. The process flow, according to a law of conservation and conversion of energy and a theory of utilizing physical and thermodynamic properties of a working substance to use a low-temperature heat source as a high-temperature source through heat pump equipment, wherein the theory is obtained through a plurality of years of research by the inventor; and the process flow utilizes physical and thermodynamic properties of water and a series of technologies and equipment of solar power plants which have lower power generation cost than the thermal power generation to convert the heat of the sewage into high-temperature high-pressure water vapor to push steam turbines to generate electricity, and realizes the high purification treatment to the sewage to produce water which meets the direct drinking standard and tap water with high water quality.

Description

Technical field: [0001] The invention relates to the technical field of generating high-temperature and high-pressure steam by using a low-temperature heat source to drive a steam turbine to generate electricity and sewage treatment. Background technique: [0002] Energy is a necessity for human survival, and the method of burning fuel to obtain energy has begun to develop to the point where it endangers the survival of human beings; and the massive discharge of sewage is another extremely serious problem that threatens the living environment of human beings. [0003] At present, there is no river that is completely free from pollution in my country, and the massive discharge of urban sewage is a major public hazard. Not only seriously pollute the environment, but also seriously threaten the health of the people. Therefore, cheap non-polluting energy and cheap sewage treatment and regeneration technology have become a world-recognized problem in the world. [0004] The pur...
