Background technique

Outdoor high-temperature pipelines are an important part of transporting high-temperature fluid media. In order to ensure the temperature of the fluid medium and prevent condensation, high-temperature pipelines need to be installed with electric heating systems and insulation layers. In some cases, electric energy sensors are also required to detect the fluid medium in the pipeline. Temperature, pressure, flow rate, chemical properties, etc., especially in photothermal power stations, the high-temperature pipes are very long, the high-temperature pipe insulation system not only needs to have a good heat preservation effect, but the DCS system of the power station also needs to monitor the temperature, pressure, and Flow velocity, chemical properties, etc., by collecting these data to adjust the defocusing and focusing of the collector, and then control the flow of the heat transfer medium.

In the existing outdoor high-temperature pipeline insulation technology, the pipeline is equipped with an electric heat tracing system and a heat preservation system. The insulation layer uses materials with good heat insulation performance and good thermal expansion performance. The shell of the insulation layer generally uses aluminum shells with good flexibility, etc. Similar materials, during the day, the sun shines on the shell and reflects into the air, which has not been used in any way. At the same time, these shell materials are easily oxidized and damaged, which affects the thermal insulation effect.

In terms of fluid data monitoring in pipelines, the existing technology generally uses electric energy sensors for monitoring. Although these electric energy sensors are small in power, they also need power supply and signal monitoring and transmission. The traditional way of power supply and communication is to use wired methods. If it is relatively large, a large number of long-distance cables must be used. Long-distance cables have high resistance and high power consumption. Long-distance wired signal transmission will also cause signal delay and distortion. Using a large number of cables will also increase construction costs and maintenance costs. Failure rate high.
