Embodiment Construction

[0029] 1. Replace the heat collector tube used in the trough solar thermal power generation device with the line-focused enhanced heat-collector tube (2) of the annular wave node or the helical wave-node metal inner tube with enhanced heat transfer function, and give full play to the line-focused enhanced heat collector tube ( 2) For the disturbance effect of the heat transfer working medium, the laminar flow heating is changed to the eddy current heating.

[0030] 2. Use atomized gas instead of heat transfer oil or water as heat transfer medium. In order to inherit the advantages of DSG technology and overcome the shortcomings of directly heating the water working medium, atomization devices such as vaporization tank (3) or jet pump (4) are selectively added to the working fluid inlet of the parabolic trough heat collecting device and the light collecting array, These devices are used to generate atomized water vapor, and the "steam" gas is used to complete heat transfer.

Abstract

The invention relates to a device which realizes groove type concentrating solar power (CSP) by using heat transfer of atomization water vapor working medium and atomization flash evaporation. In the device, heat exchange is reinforced and atomization water vapor is input under control by the principle that a linear focusing reinforced heat collecting pipe disturbs gas in the pipe, saturated steam or overheated steam is produced in a light gathering array, and a steam turbine is driven to drive a generator, so that the groove type CSP device is realized. The technology belongs to the field of utilization of solar energy heat.

Description

technical field [0001] The invention relates to a device for realizing trough solar concentrating power generation (CSP) by using atomized water vapor heat transfer medium and atomized flash evaporation. Controlled input atomized water vapor while heating, generating saturated steam and superheated steam in the concentrating array, and finally driving the steam turbine and driving the generator to complete the trough solar thermal power generation device. The technology belongs to the field of solar thermal utilization. Background technique [0002] With the vigorous development of the use of renewable energy such as solar energy all over the world, concentrated solar power (CSP) has been gradually recognized by people. Compared with photovoltaic solar power (PV), concentrating solar power (CSP) has outstanding features such as large scale, high concentration, and high efficiency, but the common problems faced are how to reduce investment costs and how to improve power gene...
