Problems solved by technology

Mineral heat transfer oil is obtained by extracting a certain fraction during petroleum processing, refining it, and then adding various additives. The production cost of mineral heat transfer oil is low and the price is not high. However, it is easy to solidify at low temperature and easy to solidify at high temperature. It is easy to oxidize and has a short service life; synthetic heat transfer oil is a pure or relatively pure chemical, which has the characteristics of good thermal stability, high service temperature, long life and renewable, but its production cost is very high and expensive

Abstract

The invention discloses a thermal conduction liquid used by a groove-type solar photo-thermal power generation system, and belongs to the field of energy chemistry. The formula of the thermal conduction liquid is characterized by consisting of extract oil of cracked heavy oil, poly(1-decene), poly-dodecylene, phenyl silicone fluid and method silicone fluid. The thermal conduction liquid provided by the invention has the advantages of low freezing point, high usage temperature, good heat stability, long service life and the like, and is better in techniques and performances compared with conventional mineral-type thermal conduction liquids; because of the relatively low price, the thermal conduction liquid provided by the invention is better in economical benefit compared with synthetic-type thermal conduction liquids; and the thermal conduction liquid provided by the invention is developed specially for the groove-type solar photo-thermal power generation system, and belongs to high-cost-performance thermal conduction liquids.

Description

technical field [0001] The invention relates to a heat transfer fluid used in a trough solar photothermal power generation system, and belongs to the field of energy chemistry. Background technique [0002] At present, the heat transfer medium used in mature and commercial trough solar thermal power generation systems is heat transfer fluid, which is divided into mineral type and synthetic type. Mineral type heat transfer fluid is called mineral heat transfer oil, and synthetic type heat transfer fluid It is called synthetic heat transfer oil. Mineral heat transfer oil is obtained by extracting a certain fraction during petroleum processing, refining it, and then adding various additives. The production cost of mineral heat transfer oil is low and the price is not high. It is easy to oxidize and has a short service life; synthetic heat transfer oil is a pure or relatively pure chemical, which has the characteristics of good thermal stability, high operating temperature, lon...
