Problems solved by technology

[0003] Disadvantages of the above structure include: during operation of the device for adjusting the belt fastening force, it will be difficult to access (accessibility) frame member (frame member); , the installation of the TIM is very complex; where the through-hole is lined with a metal tube and used for threaded fixings
[0005] However, the field of application of this prototype is limited due to the fact that the TIM is fixed to an element soldered to the device to be insulated
In other words, this prototype cannot be applied to thermal insulation of power generation equipment, especially NPP equipment
Another disadvantage of this prototype consists of the fact that due to the direct positioning of the TIM on the surface of the equipment to be insulated, the inhomogeneous distribution of the thermal resistance due to the different fit of the TIM on the surface of the equipment to be insulated leads to inhomogeneous Ensure that the surface isothermal
Therefore, thermal stress will be generated on the housing of the equipment to be insulated, resulting in a reduction in the reliability of the equipment to be insulated

Embodiment Construction

[0050] best practice

[0051] The modular removable thermal insulation structure according to the invention comprises circular segments 2 distributed longitudinally in series on the outer surface of the equipment to be insulated, for example the outer surface of the pipe 1; and the circular segments 2 close to each other. Each circular segment consists of N identical thermal insulation modules (TIM) 3 . The thermal insulation modules 3 abut against each other; and the side walls of the TIM 3 of adjacent sections are arranged opposite to each other. Thus, each of the four corner posts between the side walls of each TIM 3 butts along a joint line 4; wherein this joint line 4 extends in a direction normal to the surface of the device to be insulated. On the one hand, between the side walls of the TIM 3 there is a corner fitting corresponding to each corner post, the corner fittings being located in the same segment and in the vicinity of the TIM 3 . On the other hand, there ar...

Abstract

The present invention relates generally to the thermal insulation technology, and more particularly to a thermal insulation for equipment at nuclear power plants (NPPs). The advantages of the present invention includes the widening of the field of application; the simplification of both installation and dismantling of the thermal insulation modules; an increase in the isothermality of an equipment to be thermally insulated; a uniform distribution of a temperature field within the thermal insulation volume along the length thereof; and the possibility of monitoring the state of the equipment body without need to remove the thermal insulation modules.

Description

technical field [0001] The present invention relates to thermal insulation technology, and more particularly, to a thermal insulation structure (thermal insulation) for nuclear power equipment (NNP). Background technique [0002] A modular removable insulation structure is known in the prior art, comprising a tie band type housing and an enclosure. Wherein, the strap-type housing has a threaded seat body and is positioned so that the fixed wire is located on the outer surface of the device to be insulated. The casing surrounds the above-mentioned equipment to be insulated, and includes an N-face outer surface and an N-face inner surface. The housing is composed of circular sections; wherein said circular sections are successively distributed longitudinally on the device to be insulated and abut against each other. Each circular segment consists of N identical thermal insulation modules (TIMs). The thermal insulation modules are butted against each other, and the respectiv...
