Abstract

The invention discloses an anti-condensation system for preventing condensation of heat conduction oil used for groove type solar photo-thermal power generation, and relates to an anti-condensation system.The anti-condensation system aims to solve the problem that the heat conduction oil inside a heating collecting device is naturally cooled and condensed if not being used for a long time or in cold weather after heat of a heat accumulation device in a conventional groove type solar photo-thermal power generation plant is used up. The anti-condensation system comprises at least three boilers and at least two sets of pump valve systems, wherein each set of the pump valve system comprises a conveying pump and an adjusting valve; heat conduction oil input ends of the conveying pumps in the pump valve systems are all used for being communicated with heat conduction oil inlet ends of corresponding adjusting valves; heat conduction oil outlet ends of the adjusting valves in each set of the pump valve system are respectively communicated with the heat conduction oil inlet end of each boiler; and heat conduction oil outlet ends of the boilers are used for being respectively communicated with a mirror field of a groove type solar photo-thermal power generation station. The anti-condensation system is used for preventing the heat conduction oil for the solar photo-thermal power generation from being condensed.

Description

technical field [0001] The invention relates to an anti-condensation system, in particular to an anti-condensation system for preventing condensation of heat transfer oil for trough solar thermal power generation. Background technique [0002] Solar thermal power generation technology has just started in China, and many technologies are in the exploratory stage. Solar power plants have to be started and stopped every day. When the heat of the heat storage system is used up at night, stop the power island (the part of the system connected to the heat exchange system for heat exchange) , if no measures are taken at this time, the heat transfer oil will naturally dissipate heat and cause solidification, especially in cold weather in winter, so that the solar power plant cannot work. Therefore, measures must be taken to avoid this phenomenon. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the heat conduction oil in the heat...
