Energy-saving safe support system applied to solar heat power generation

Abstract

The invention discloses an energy-saving safe support system applied to solar heat power generation. The support system is used for supporting a fused salt pipeline and comprises a main frame and heatinsulation blocks, wherein the heat insulation blocks are distributed on the main frame; a protection layer is also arranged on the main frame and is prepared from the following components in parts by mass: 15-20 parts of organosilicone-modified epoxy resin, 10-15 parts of alcohol-soluble acrylate resin, 15-18 parts of ATO powder, 1-3 parts of potassium hexatitanate whisker, 2-4 parts of compoundferrotitanium powder, 10-12 parts of alcohol, 6-8 parts of sepiolite, 3-5 parts of glass powder, 5-10 parts of a dispersant, 5-8 parts of a leveling agent, 6-8 parts of a defoaming agent, 5-7 parts of a thickening agent, 1-2 parts of an ultraviolet absorbent, 1-3 parts of a cross-linking agent and 0.02-0.04 part of rare-earth element. The support system is simple and compact in structure, low incost and long in service life, and has excellent heat insulation performance and corrosion resistance.

Description

technical field [0001] The invention relates to a support system, in particular to an energy-saving safety support system for solar thermal power generation. Background technique [0002] Solar thermal power generation is one of the important directions for the development of the new energy industry. After decades of development, it has entered a comprehensive commercialization stage in foreign countries, while my country's solar thermal power generation business is just in its infancy, and is currently mainly in the research and development of key technologies. , system integration and project demonstration phase; [0003] High-temperature molten salt is a heat storage medium with low cost, long life, and good heat transfer and energy storage performance. It can be used not only as a latent heat storage material, but also as a sensible heat material in a solar thermal power station in a high-temperature molten state. , for molten salt pipelines, due to the high freezing poi...

AI Technical Summary

Problems solved by technology

[0007] At present, the safety support system is generally used for long-distance steam transmission pipelines and related pipelines in the petrochemical industry. The pipe diameter is generally large and the number of pipe diameter specifications is relatively small. For the problem of processing accuracy, the thickness of the heat insulation block is generally not more than 50mm. If it is too thick, the stress concentration will easily cause the heat insulation block to break. Compared with the general support system, the heat dissipation loss can be reduced by about 65%. At the same time, the structure of the general support system is relatively simple. , which is basically a pipe clamp seat type, which cannot meet the requirements of the solar thermal power generation pipeline system. In addition, the heat insulation material has a high density, and the safety support system is much heavier than the general support system, which greatly increases the pipeline load;

[0008] Through the investigation of support and hanger manufacturers at home and abroad, there is currently no standard for safety support systems at home and abroad, and there is no standard safety support system for solar thermal power generation molten salt pipelines. In addition, the current safety support system is only through Increase heat insulation block to reduce heat dissipation loss, without considering reducing heat dissipation loss of support and hanger from its own structure or material
