Steam generator

Abstract

The invention discloses a steam generator which comprises a tank body and a solar outer heating pipe. A liquid inlet pipe is arranged on the side wall of the tank body, two symmetrical air outlet pipes are arranged on the side wall of the top end of the tank body, spraying nozzles are rotationally arranged on the inner walls of the two air outlet pipes, and a plurality of spiral protrusions are installed on the inner walls of the spraying nozzles; longitudinal movement grooves communicated with the air outlet pipes are formed in the inner wall of the tank body, and guide plates arranged in a sliding manner through balls are arranged in the longitudinal movement grooves; and the axes of the air outlet pipes right face the bent outer conical surface, and a solar inner heating pipe is fixed into the solar outer heating pipe through a flange. After steam is discharged into the tank body, the guide plates with the middle portions downwards protruding to form inversed cones are arranged at the top of the tank body, and the outer conical faces of the inversed cones are inwards bent along the center lines of the inversed cones; and in other words, longitudinal sections of the inversed cones are in inversed ridge shapes, the guide plates provide a curve route guidance for motion of the steam, and free dropping caused by partial moisture fusion caused by accumulation of moisture at the top of the tank body is prevented.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a steam generator. 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 conversion methods. One is to directly convert sol...

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
