Detachable heat preservation block integrating electric heating function

Abstract

The invention belongs to the technical field of reactor sodium-related heat preservation, and particularly relates to a detachable heat preservation block integrating an electric heating function. Thedetachable heat preservation block integrating the electric heating function is used for heat preservation and heat tracing of a sodium-related pipeline (10) of a sodium-cooled fast reactor. The detachable heat preservation block integrating the electric heating function includes a high temperature-resistant, soft and detachable heat preservation sleeve (4), a soft internal heat preservation layer arranged in the heat preservation sleeve (4), an electric heating wire (7) arranged on the heat preservation sleeve lower upper surface (6) facing the sodium-related pipeline (10) and a fast connector (1) arranged on the heat preservation sleeve upper surface (5) for being connected with power supply, and the two ends of the electric heating wire (7) penetrate into the heat preservation sleeve (4) and connected to the fast connector (1) to obtain the power supply; and the heat preservation block can be bent, and a plurality of heat preservation blocks can be connected to cover the external surface of the sodium-related pipeline (10) with the radian of the external surface of the sodium-related pipeline (10). The detachable heat preservation block integrating the electric heating functionhas the characteristics of simple structure, convenient use and installation, good heat preservation effect, easy maintenance, low cost, and the like.

Description

technical field [0001] The invention belongs to the technical field of sodium-related thermal insulation of reactors, and in particular relates to a detachable thermal insulation block with integrated electric heating function. Background technique [0002] At present, in the application of metal-cooled fast reactors, there is a detachable thermal insulation structure scheme using a stainless steel shell, but the use of a stainless steel shell increases the total weight of the thermal insulation device on the one hand, puts higher requirements on the mechanical design of the system piping, and also poses problems for installation and maintenance. Certain adverse effects; on the other hand, stainless steel is used as the main support structure, the thermal bridge phenomenon is obvious, and the heat leakage is serious, so it is not suitable for scenes with higher temperature or higher heat preservation requirements. [0003] In the fourth-generation metal-cooled fast reactor, ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the integration problem of electric heating wire parts and soft detachable thermal insulation structure modules in fast reactor sodium-related pipelines and equipment systems

The design of the soft detachable insulation cover solves the problem that the hard insulation shell has poor insulation effect and is not suitable for high-temperature equipment insulation. Secondly, through the combination of the electric heating wire and the soft detachable insulation solution, the hard protection structure is improved to limit the electric current. The problem of the heating effect of the heating wire, at the same time, the modular design can simplify the installation and construction and subsequent maintenance operations, reduce the overall cost, and improve the comprehensive economic benefits
