Solar fixed focus multi-dish collector thermal power generation system

Abstract

The invention relates to a solar fixed-focus multi-dish heat collector thermal power generation system, which is composed of a heat collector, a heat storage device, a steam generator, a superheater, a turbogenerator set, an air cooler and a condensate tank. The hot oil pipe and the cold oil pipe are respectively connected to the heat accumulator through the hot oil main pipe and the cold oil main pipe, and a circulating oil pump is installed on the cold oil main pipe, and the heat accumulator and the steam generator are respectively connected by an oil return pipe and an oil delivery pipe , a hot oil pump is installed on the oil return pipe, the steam generator and the superheater are connected by a steam pipe, the superheater is connected to the turbogenerator through the superheater pipe, the turbogenerator is connected to the air cooler by the steam pipe, and the air cooler is connected through the condensing The water pipe is connected to the condensate tank, and the condensate tank is connected to the steam generator through the condensate pipe, and the condensate pump and iron remover are installed on the condensate pipe. The invention adopts a fixed focusing multi-dish heat collector to construct a light field, and has the advantages of strong wind resistance, high conversion rate of light to heat and electricity, and heat loss of heat pipes.

Description

technical field [0001] The invention belongs to the technical field of solar thermal power generation engineering, and relates to a thermal power generation system of a solar fixed focusing disc heat collector. Background technique [0002] The existing solar thermal power generation engineering system with the trough collector as the mainstream to build the light field still has the following deficiencies in practical application: (1) The trough collector is in the form of single-axis tracking, and the concentration ratio is low. The conversion rate is low, only 60% to 65%; (2), the wind resistance is poor; (3), the heat loss of the heat pipe is large. In view of the constraints of the above reasons, the heat loss of the thermal pipeline of the existing trough collector thermal power generation system is relatively large, the light-to-heat conversion efficiency is relatively small, and the operating cost is relatively high. How to improve the light-to-heat conversion effic...
