Abstract

The invention relates to a preheating and solidification-preventing conveying pipeline structure which comprises an inner pipeline and an outer pipeline. The end portion of the inner pipeline and the end portion of the outer pipeline are in sealed connection. A closed cavity structure is defined by the inner pipeline and the outer pipeline. A vacuum layer is formed in the cavity structure. The inner pipeline is a steel pipeline. The preheating and solidification-preventing conveying pipeline structure further comprises an electric heating circuit used for heating the inner pipeline after being electrified. The electric heating circuit is electrically connected with the inner pipeline. The steel inner pipeline is used as a resistor, electric energy is provided for the inner pipeline through the electric heating circuit, electric energy heating is conducted on the inner pipeline, and the preheating and solidification-preventing conveying pipeline structure can reach the needed temperature within a short time. The preheating and solidification-preventing conveying pipeline structure is convenient to operate, short in heating time, even in heating effect, capable of effectively reducing solidification of the pipelines and capable of prolonging the service life of the pipelines.

Description

technical field [0001] The invention relates to the field of photothermal power generation, in particular to a preheating and anti-solidification transport pipeline structure. Background technique [0002] In recent years, with the development of the global economy, traditional energy sources such as coal, oil, and natural gas have limited reserves, and energy supply and demand have begun to appear contradictory. People began to study various renewable energy sources, wind energy, geothermal energy, hydrogen energy, solar energy, etc. have been paid more and more attention by people, among which the most potential is the utilization of solar energy. Solar thermal utilization is one of the methods with the most mature technology, high conversion efficiency and relatively low price at present. Solar thermal power generation has become a new energy development due to its characteristics of energy storage, peak adjustment, continuous power generation, power quality is exactly t...
