High temperature pipeline heat insulation wall-penetrating structure and folding sleeve thereof

Abstract

The invention discloses a high temperature pipeline heat insulation wall-penetrating structure and a folding sleeve thereof. The high temperature pipeline heat insulation wall-penetrating structure comprises the folding sleeve, a high temperature pipeline and a wall body; the folding sleeve is provided with a channel corresponding to the high temperature pipeline, and the extension direction of the channel is parallel to the axis direction of the folding sleeve; the side wall of the folding sleeve is formed by back-folding along the axis direction of the folding sleeve through a folding plate;the tail end, away from one side of the channel, of the folding plate extends outside in the radical direction of the folding sleeve and forms a connecting part used for connecting with the wall body; an installing hole is formed in the wall body corresponding to the folding sleeve, and the folding sleeve is arranged in the installing hole in a penetrating mode; and the high temperature pipelineis arranged in the channel in a penetrating mode, and thus the side wall of the folding sleeve is clamped between the high temperature pipeline and the wall body. According to the high temperature pipeline heat insulation wall-penetrating structure and the folding sleeve thereof, temperature of the wall body in connection with the pipeline is efficiently lowered, damage and thermal stress deformation caused by high temperature of the wall body is avoided, and high temperature damage on the other parts of the wall body is avoided. The folding sleeve has the displacement compensation ability dueto the back-folding structure, and vibration and sliding moving of the high temperature pipeline are efficiently prevented.

Description

technical field [0001] The invention relates to the technical field of high-temperature pipeline heat insulation, in particular to a high-temperature pipeline heat-insulation wall penetration structure and a folding sleeve thereof. Background technique [0002] During the heat-insulated transportation of pipelines that circulate high-temperature flue gas, exhaust gas or steam, etc., they often pass through walls such as box walls and walls. Some walls cannot withstand high-temperature environments, and some pipelines will There are different degrees of displacement and vibration in the three-dimensional direction, which requires that the pipe must be firmly fixed on the wall when it passes through the wall. [0003] However, high-temperature pipes are often rigidly fixed directly between the metal structure and the wall. The metal structure has a large thermal conductivity, which makes it very easy for the high-temperature pipe to transfer heat to the wall. On the one hand, ...

[0003] However, high-temperature pipes are often rigidly fixed directly between the metal structure and the wall. The metal structure has a large thermal conductivity, which makes it very easy for the high-temperature pipe to transfer heat to the wall. On the one hand, it causes heat loss in the high-temperature pipe. The wall and other appendages on the wall were damaged by high temperature

If the existing insulation material is used to cover the pipeline through the wall and fixed rigidly, the pipeline cannot be stably fixed on the wall due to the soft properties of the insulation material. When the pipeline vibrates violently, the vacuum interlayer is easily pulled, deformed or even damaged, resulting in a short service life
