Steam generation tank used for power station

Abstract

The invention discloses a steam generation tank used for a power station. The steam generation tank comprises a tank body and a solar outer heat pipe. A liquid inlet pipe is arranged on the side wall of the tank body. Two symmetrical gas outlet pipes are arranged on the side wall of the top end of the tank body. Spray nozzles are arranged on the inner walls of the two gas outlet pipes in a rotating manner. A plurality of spiral protrusions are arranged on the inner walls of the spray nozzles. A diversion plate is fixed to the top end of the tank body. The axes of the gas outlet pipes are right opposite to the bent outer conical face. A solar inner heat pipe is fixed in the solar outer heat pipe through a flange. After water steam is discharged into the tank body, the diversion plate with the middle protruding downwards to form a reverse conical shape is arranged on the top of the tank body, the outer conical face of the reverse conical shape is bent inwards along the center line of the outer conical face, and in other words, the longitudinal section of the reverse conical shape is in a reverse ridge shape, and the diversion plate provides cambered surface path guidance for movement of the water steam; and while discharge of the water steam is accelerated, it is prevented that the water steam is accumulated on the top of the tank body and part of water and steam are fused and then freely fall.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a steam generating tank used in a power station. 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. ...

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
