Trough type heat collector control method and device

Abstract

The invention discloses a groove type heat collector control method and device, and belongs to the field of light energy heat utilization device control, and the method comprises the steps that temperature information of a heat-conducting medium in a heat collecting pipe and day-by-day position information of a reflective mirror are obtained; and determining offset focus position information of the reflector according to the temperature information and the day-by-day position information. And based on the temperature information of the heat-conducting medium and the day-by-day position information, the offset focus position information of the reflective mirror is confirmed to adjust the position of the reflective mirror and change the heat collection rate of the reflective mirror, so that the temperature of the heat-conducting medium in the heat collection pipe is adjusted, the temperature fluctuation of the heat-conducting medium is reduced, and the heat-conducting temperature is kept within a reasonable range. Therefore, the service life of the heat-conducting medium and the service life of the heat collector can be prolonged.

Description

technical field [0001] The application belongs to the field of control of light-energy-heat utilization devices, and in particular relates to a control method and device for a trough-type heat collector. Background technique [0002] Green energy is the long-term planning policy of energy conservation and emission reduction in my country. The trough collector is a method of light-to-heat conversion, which realizes the conversion of light energy to heat energy through the processes of focusing, reflection and absorption, so that the heat exchange medium reaches a certain level. temperature to meet the needs of different load collectors. The trough collector belongs to the category of medium and high temperature collectors, which can make the heat exchange working medium obtain a relatively high temperature, and can be used in thermal power generation, seawater desalination, heating engineering, absorption refrigeration and other life and production fields. Light energy is the...

Problems solved by technology

However, the temperature of the heat transfer medium in the heat collection tube of the trough heat collector fluctuates greatly, and the temperature of the heat transfer medium will seriously exceed the set temperature, which will shorten the service life of the heat transfer medium and the heat collector.
