Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] Such as figure 1 , a solar photothermal vapor-liquid two-phase flow thermal expansion power generation system, which is composed of a solar trough line focusing collector array, a booster pump, a vapor-liquid two-phase flow thermal expansion power machine, a generator and corresponding pipelines, characterized in that :

[0036]There is a heat collecting well which is provided with supplementary water by the water treatment device (providing the working medium water of the water collecting well for the water treatment device at the start of operation), and the circulating hot water in the heat collecting well is pumped to the main water supply pipe by the booster pump to supply the jellyfish. The water pressure of the pipe is steplessly adjustable from 1.0-1.7Mpa. The main water supply pipe distributes the circulating hot water to the solar collector array. Li...

Abstract

The invention discloses a solar photo-thermal vapor-liquid two-phase flow thermal expansion power generating system. The system consists of a solar thermal collector array, a booster pump, a vapor-liquid two-phase flow thermal expansion power machine, a generator and corresponding pipelines, and is characterized by being provided with a hot water-collecting well which is supplied with water by a water treatment device, wherein circulated hot water in the hot water-collecting well is pumped to a water supply main pipe through the booster pump; the water supply main pipe is used for distributing the circulated hot water to the solar thermal collector array; the circulated hot water is heated to a saturation temperature through all heat receivers of the solar thermal collector array and then is collected to a vapor-liquid two-phase flow saturation water main pipe; vapor-liquid two-phase flow saturation water in the vapor-liquid two-phase flow saturation water main pipe is matched with vapor-liquid two-phase working medium parameters through an expanded vapor-liquid matcher and then is conveyed to the vapor-liquid two-phase flow thermal expansion power machine to do work and drive the generator to operate; and vapor-liquid two-phase working media after work application flow back to the hot water-collecting well for recycling through a backflow pipeline.

Description

(1) Technical field: [0001] The invention belongs to the conversion and utilization technology of solar thermal energy, and specifically relates to a technical method and a system for generating high-efficiency and low-cost power generation with thermal energy collected by solar heat collectors. (two) background technology: [0002] Solar thermal power generation is the use of heat collectors to convert solar radiation energy into heat energy, and generate electricity through a thermodynamic cycle process, which is an important way to utilize solar energy. Since the 1980s, the United States, Europe, Australia and other countries have successively established different types of demonstration devices, which have promoted the development of solar thermal power generation technology. The world's existing solar trough line focused thermal power generation system methods, construction costs, system efficiency, and power generation costs are as follows: [0003] (1) Power generati...
