Steam generation device with solar thermal power generation function

Abstract

The invention discloses a steam generation device with a solar thermal power generation function. The steam generation device comprises a tank body and a solar power outer heat pipe. A liquid inlet is formed in the side wall of the tank body. Two symmetric 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 of the guide plate protrudes downwards to form an inverted cone. The outer conical surface of the inverted cone is bent inwards along the central line of the inverted cone. The axis of each air outlet right faces the outer conical surface of the bend. A solar power inner heat pipe is fixed in the solar power outer heat pipe through a flange plate. After steam is discharged into the tank body, the top of the tank body is provided with the guide plate with the middle protruding downwards to form the inverted cone. Moreover, the outer conical surface of the inverted cone is bent inwards along the center line of the inverted cone, namely the longitudinal section of the inverted cone is in an inverted ridge shape, the guide plate provides a cambered path guidance for movement of steam, and while steam exhaust is accelerated, the phenomenon that due to the fact that the steam is accumulated on the top of the tank body, part of water and steam which are fused fall freely is avoided.

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
