Steam generator using solar thermal power generation

Abstract

This invention discloses a steam generator using solar thermal power generation. The steam generator comprises a tank body and an external solar thermal tube. A liquid inlet is formed in the side wall of the tank body. Two symmetrical air outlets are formed in the side wall of the top end of the tank body. A guide plate is fixedly arranged at the top end of the tank body. The middle portion of the guide plate protrudes downwards to form an inverted cone shape. The outer conical face of the inverted cone is bent inwards along the center line of the outer conical face. The axis of the air outlet right faces the bent conical face. Internal solar thermal tubes are fixed into the external solar thermal tube through flange plates. According to the steam generator using solar thermal power generation, after steam is discharged into the tank body, the guide plate with the middle portion protruding downwards into the inverted cone shape is arranged on the top of the tank body, the outer conical face of the inverted cone shape is bent inwards along the center line of the outer conical face, namely, the longitudinal section of the inverted cone shape is an inverted ridge shape, the guide plate provides a curved route guide for movement of steam, steam drainage is accelerated, and meanwhile the situation that the steam is accumulated on the top of the tank body and consequently part of steam is mutually fused and falls off freely is prevented.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a steam generating device utilizing solar thermal power generation. Background technique [0002] There are two types of solar power generation, one is solar power generation (also known as solar light power generation), and the other is solar thermal power generation (also known as solar thermal power generation). Solar photovoltaic power generation is a power generation method that directly converts solar energy into electrical energy. It includes four forms of photovoltaic power generation, photochemical power generation, photoinduction power generation and photobiological power generation. In photochemical power generation, there are electrochemical photovoltaic cells, photoelectrolytic cells and photocatalytic cells. Solar thermal power generation is to convert solar energy into thermal energy first, and then convert thermal energy into electrical energy. It has two co...

Problems solved by technology

[0003] After the solar thermal energy exchanges heat with the medium, the generator is driven by the heat engine to generate electricity. However, in the process of heat energy conversion, the partial medium steam gathers into water droplets and accumulates in the conduit before entering the heat engine, making the transfer of heat energy relatively difficult in the conduit. Large losses, thereby reducing the power generation efficiency of the heat engine
