Abstract
The utility model relates to a pipeline for conveying heavy viscous thermal sensitive materials, in particular to a heating and heat insulation pipeline for conveying heavy viscous thermal sensitive materials, which comprises a conveying working pipeline and is characterized in that an outer protecting pipeline is arranged on the periphery of the conveying working pipeline, a heating layer is arranged between the inner wall of the outer protecting pipeline and the outer wall of the conveying working pipeline, and the conveying working pipeline and the outer protecting pipeline form an interlayer combination pipeline. The heating layer at one end of the interlayer combination pipeline is communicated with a steam inlet pipe, and the other end of the interlayer combination pipeline is communicated with the steam return pipe. As to a longer interlayer combination pipeline, the pipeline is divided into a plurality of sections, a steam inlet and return pipe and a steam return pipe are respectively arranged on each section, and multi-section heating and heat insulation are conducted on the whole pipeline. The pipeline utilizes steam as a heating body, the steam is guided in the heating layer, and heat is transferred through steam to heat materials flowing through the conveying working pipeline. The pipeline has the advantages of being small in volume, high in heat efficiency, convenient to install and maintain and long in service life and the like.
Description
Technical field
The utility model relates to a kind of pipeline of carrying heavy stickiness heat sensitive material, specifically a kind of heat tracing pipeline that is used to carry heavy stickiness heat sensitive material.
Background technique
Using Molten sulphur to carry out in the production process of granulation,, in the course of conveying of molten sulfur, generally be employed in the conveyance conduit side and follow a steam tube because molten sulfur belongs to heavy stickiness heat sensitive material; Carry the thermal insulation pipe that also has employing to constitute by steel pipe, glass fibre reinforced plastics inner sheath, glass fibre reinforced plastics casing for short distance.Above traditional heat preserving mode only is incubated does not have heating, when running into the low or temperature of charge of ambient temperature when low, often has material fluidity to reduce, and hangs over the phenomenon of tube wall and the material knot occurs, even causes " knot is dead " pipeline because material is condensed in the pipeline; And owing to can not heat, the pipeline of " knot is dead " can only be removed, and it is frequent to cause pipeline to change, and cost of production is increased.
The model utility content
In order to overcome the deficiency that above-mentioned prior art exists, the purpose of the utility model just provides a kind of material knot of eliminating and hangs over tube wall, carries effective being used to carry the heat tracing pipeline of heavy stickiness heat sensitive material.
The purpose of the utility model realizes through following technological scheme.
A kind of heat tracing pipeline of carrying heavy stickiness heat sensitive material to use; Comprise the transportation work pipeline; It is characterized in that: the outer periphery of transportation work pipeline is equipped with outer pillar road, is provided with zone of heating between the inwall in outer pillar road and the outer wall of transportation work pipeline, and the transportation work pipeline constitutes the interlayer combination pipe with outer pillar road; The zone of heating of interlayer combination pipe one end is connected with the steam steam inlet pipe, and the other end is connected with the steam return tube.
Interlayer combination pipe for long can be provided with duct segments respectively steam at every section and advance return tube and steam return tube, and the whole piece pipeline is carried out the multistage heat tracing.
The connection of pipeline adopts the wafer type flange to connect.
The utility model is heater with steam, to the logical steam of zone of heating, by steam the transportation work pipeline outer wall is directly heated, through the heat conduction, to the material heating of flowing through in the transportation work pipeline.The utlity model has advantages such as volume is little, the thermal efficiency is high, installation and maintenance are convenient, long service life, be particularly suitable under the big situation of environmental change, need pipe tracing to carry the usefulness of heavy stickiness heat sensitive material.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1-outer pillar road, 2-transportation work pipeline, 3-steam steam inlet pipe, 4-steam return tube, 5-wafer type flange, 6-zone of heating.
Embodiment
As shown in the figure: a kind of heat tracing pipeline of carrying heavy stickiness heat sensitive material to use; Comprise transportation work pipeline 2; The outer periphery of transportation work pipeline 2 is equipped with outer pillar road 1, is provided with zone of heating 6 between the inwall in outer pillar road 1 and the outer wall of transportation work pipeline 2, and transportation work pipeline 2 constitutes the interlayer combination pipe with outer pillar road 1; The zone of heating 6 of interlayer combination pipe one end is connected with steam steam inlet pipe 3, and the other end is connected with steam return tube 4.Two sections interlayer combination pipes adopt wafer type flange 5 to connect.
Interlayer combination pipe for long can be provided with steam respectively at every section and advance return tube and steam return tube with interlayer combination pipe people for being divided into multistage, and the whole piece pipeline is carried out the multistage heat tracing.People described herein is segmentation; It doesn't matter with the natural segment length of interlayer combination pipe itself; Form a heat tracing pipeline of carrying heavy stickiness heat sensitive material to use like ten sections interlayer combination pipes by 5 butt joints of nine place's wafer type flanges; Can be artificial this pipeline is divided into five sections, the zone of heating of every section front end is connected with the steam steam inlet pipe, the rear end is connected with the steam return tube.
