Abstract

Disclosed is a novel heat distribution pipeline thermal insulation pipe pier system in the technical field of petrochemical engineering. The novel heat distribution pipeline thermal insulation pipe pier system comprises a heat distribution pipeline, a steel plate, wedges, MQK nanometer aerogel layers, galvanized sheet iron, hydrophobic silicate cotton and a U-shaped steel band, wherein the steel plate is fixedly connected with a pipe pier; the first MQK nanometer aerogel layer is arranged on the upper surface of the steel plate; the second MQK nanometer aerogel layer is arranged in grooves of the upper surfaces of the wedges; the third MQK nanometer aerogel layer, the hydrophobic silicate cotton and the galvanized sheet iron sequentially wrap the outer surface of the heat distribution pipeline. A heat bridge between a high-temperature pipeline and the pipe pier can be completely cut off, the surface temperature and the heat flux of the pipe pier are substantially reduced, heat loss is remarkably reduced, and a large amount of heat energy is saved. The novel heat distribution pipeline thermal insulation pipe pier system is reasonable in design, simple in structure and applicable to the optimized design of the heat distribution pipeline thermal insulation system.

Description

technical field [0001] The invention relates to a pipeline thermal insulation system in the technical field of petrochemical industry, in particular to a novel thermal pipeline thermal insulation pier system with a nano-airgel layer. Background technique [0002] Heavy oil, called heavy crude oil abroad, refers to crude oil with a viscosity greater than 50mPa·s under oil reservoir conditions or a degassed crude oil with a viscosity greater than 100mPa·s and a density greater than 0.934g / cm3 at the reservoir temperature. In recent years, oil experts from various countries believe that the development of light crude oil is limited by reserves, and there will not be too many reserves of light crude oil for us to exploit. According to relevant data estimates, the world's light crude oil resources are 360 ​​billion tons. The recoverable reserves are 135 billion tons, while the resources of heavy crude oil are 900 billion tons, and the recoverable reserves are 180 billion tons. ...
