Description

Marine high-efficiency electric tracing band

Technical Field

The invention belongs to the technical field of electric tracing bands, and particularly relates to a high-efficiency electric tracing band for a ship.

Background

The heat tracing band has been widely used as an effective pipeline (storage tank) heat preservation and anti-freezing scheme. The working principle is that a certain amount of heat is radiated through the heat tracing medium, and the loss of the heat tracing pipeline is supplemented through direct or indirect heat exchange, so that the normal working requirements of temperature rise, heat preservation or freeze prevention are met. In the 70's of the 20 th century, the concept of replacing steam tracing with electric tracing solutions was proposed. In the late 70 s and early 80 s, electric tracing technology has been widely popularized in many industrial departments including energy industry, and steam tracing is comprehensively replaced by electric tracing. The development of electric tracing technology has been developed to date, from traditional constant power tracing to self-temperature control electric tracing with conductive plastic as core.

In real life, some ships need to travel in similar polar regions or regions with harsh natural environments and cold climates under certain conditions. And the stern of the vessel is provided with a large cargo deck for placing various items or equipment and the like. In the driving and stopping process, the icing phenomenon can often appear on the side of the deck, and crews move or work on the deck and easily fall down.

The electric tracing band in the prior art includes a core wire inside, a PTC material layer disposed outside the core wire, and an insulating layer disposed outside the PTC material layer. When the temperature-variable resistor is used, after the core wire is electrified, the PTC material layer can change the resistance based on the temperature value, so that the heating value is changed, and the heat tracing effect is realized. However, the electric tracing band in the prior art radiates heat to the periphery in the heating process, and the electric tracing band cannot directly act on the surface of the deck, so that the heat tracing efficiency is relatively low.
