Dismantling-free thermal-insulation replaceable electric heat tracing apparatus and use method therefor

Abstract

The invention discloses a dismantling-free thermal-insulation replaceable electric heat tracing apparatus and a use method therefor, and relates to an electric heating apparatus and a use method therefor. The dismantling-free thermal-insulation replaceable electric heat tracing apparatus comprises heat tracing bands, wherein multiple heat tracing band guiding rails are formed in the outer wall of thermal insulation equipment; the heat tracing band guiding rails are hollow strip-shaped slots made from a metal alloy material; the heat tracing bands are inserted in the heat tracing band guiding rails in a one-to-one correspondence manner, and then are connected to an electric control box in a parallel connection manner; and the heat tracing band guiding rails are made from an aluminum alloy material. By adoption of the dismantling-free thermal-insulation replaceable electric heat tracing apparatus and the use method therefor, the heat tracing bands which can reused are adopted to replace the existing heat tracing bands, so that convenient installation is achieved; the external thermal-insulation electric tracing elements can be replaced in dismantling-free manner, so that trouble in replacing the heat tracing bands is completely removed; in addition, a large amount of manpower and materials can be reduced; and meanwhile, the electric heat tracing apparatus adopts aluminum alloy packaging, so that the service life is long, the heat dissipation area is enlarged, fire can be prevented, explosion prevention is achieved, and an additional reliable grounding function is achieved.

Description

technical field [0001] The invention relates to an electric heating device and its use method, in particular to a replaceable electric heat tracing device without dismantling and heat preservation and its use method. Background technique [0002] In the oil field, many outdoor tanks adopt electric heat tracing for heat preservation, but due to problems such as the short service life of the heating cable, it often occurs that the heating cable cannot work normally, which will cause a series of accidents. And because the tank body has external insulation materials, the heating cable is installed between the insulation material and the tank body. If you want to replace the heating cable, you must remove the original external insulation material, and then replace the heating cable. After replacing the heating cable, To restore the external insulation again, every time the insulation is replaced, it will not only use a lot of labor, but also consume a lot of insulation materials,...

AI Technical Summary

Problems solved by technology

[0002] In the oil field, there are many outdoor tanks that use electric heat tracing for heat preservation. However, due to problems such as the short service life of the heating cable, it often occurs that the heating cable cannot work normally, which will lead to a series of accidents.

And because the tank body has external insulation materials, the electric heating cable is installed between the insulation material and the tank body. If you want to replace the heating cable, you must remove the original external insulation material, and then replace the heating cable. After replacing the heating cable, Then restore the external insulation. Every time the insulation is replaced, it will not only use a lot of labor, but also consume a lot of insulation materials, and may even cause other unnecessary troubles.
