Embodiment 1

[0032] The energy-saving support for heat transmission pipelines of this embodiment has a structure such as figure 1 , figure 2 and image 3 As shown, it includes a stent body 1 and an inner liner 2 disposed inside the stent body 1 , and both ends of the inner liner 2 are slightly longer than the stent body 1 . The cross-section of the stent body 1 is corrugated radially undulating and uniformly distributed in the circumferential direction. The crests of the corrugations have an arched convex surface a, and the troughs have an arched concave surface b. Two adjacent convex curved surfaces a and concave curved surfaces b form the basic unit of the corrugation. The bracket body 1 of this embodiment is composed of 10 basic units connected smoothly from the end to the end. The convex curved surface a and the concave curved surface in the basic unit The opening of b is opposite, the opening of the convex surface a faces the center of the base circle d, the opening of the concave ...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that: Figure 10 and Figure 11 As shown, the inner liner 2 is set on the insulation layer 4 of the working pipe 3, the bracket body 1 is placed between the inner liner 2 and the outer sleeve 5, and the space between the bracket body 1 and the inner liner 2 is filled with glass wool for heat preservation. Material 7, and between the bracket body 1 and the outer sleeve 5 is also filled with a certain thickness of glass wool insulation material 7, while leaving a certain thickness of air layer 6 between the bracket body 1 and the outer sleeve 5, that is, the bracket body 1 and the inner liner 2 are placed in the insulation material layer. This structure is suitable for the insulation pipe structure with thicker insulation layer 4 and multi-layer insulation layer 4 . Since the bracket body 1 has a plurality of corrugations, the surface area itself is relatively large. In this assembly structure, all the inner and ...

Embodiment 3

[0039] The difference between this embodiment and Embodiments 1 and 2 is that the stent body is composed of 13 corrugated basic units connected smoothly from head to tail, and the cross-sections of the inner convex curved surface and outer concave curved surface of the basic unit are sinusoidal waveforms, and the axial cross-section for the arc. In addition, the outer diameter of the stent body 1 is the diameter of the circle f formed by the vertices of all the convex curved surfaces on the stent body 1 , and the inner diameter is the diameter of the circle e formed by the vertices of all the concave curved surfaces b on the stent body 1 . (See Figure 5 ).

Abstract

The invention relates to an energy-saving support used for a heat transmission pipeline. The energy-saving support comprises a support body and a liner cylinder arranged on the inner side of the support body, the section of the support body is in a ripple shape, wherein ripples fluctuate in the radial direction and are evenly distributed in the circumferential direction, the crest and the trough of each ripple are an arched curved surface convex outwards and an arched curved surface concave inwards respectively, the vertexes of the curved surfaces, concave inwards, of the troughs make contact with the liner cylinder, and after the support body and the liner cylinder are assembled, the vertexes of the curved surfaces, convex outwards, of the crests make contact with an outer sleeve of the heat transmission pipeline. The energy-saving support has the advantages of being good in technological property, convenient to transport and install and small in contact area, the heat transmission path is lengthened, the heat dissipation loss of the support is greatly reduced, the temperature of the tail end of the support is lowered substantially, and energy is saved.

Description

technical field [0001] The invention relates to a support for pipelines, in particular to an energy-saving support for heat transmission pipelines. Background technique [0002] Thermal pipelines are pipelines for transporting thermal energy media such as steam. They are widely used in various fields of production and life at present. They are characterized by high temperature, high pressure and fast flow rate of the transported medium, which will bring great pressure to the pipeline during operation. expansion force and impact force, so it is necessary to install a bracket in the pipeline. As an important component of the thermal pipeline, the heat dissipation of the bracket has a restrictive effect on the heat transfer efficiency of the thermal pipeline. In the long-distance heat transmission pipelines of several kilometers, tens of kilometers or even tens of kilometers, a bracket is installed every ten meters to support the heat transmission pipeline. The heat dissipati...
