Description
Technical field
The utility model relates to a kind of thermal insulation apparatus, especially relates to a kind of thermal insulation apparatus of pipeline.
Background technique
Insulation is also known as thermal insulation, and thermal insulation is that minimizing system thermal is outwards transmitted or outside heat imports a kind of technological measure taked in system into.Thermal insulation comprises insulation and cold insulation.And the meaning of pipe insulation:
1) reduce scattering and disappearing of hot and cold amount, energy saving, improve the Economy of system cloud gray model;
2) temperature that can reduce outer surface is incubated to pipeline, special high-temperature pipe, improves the working condition of surrounding, prevent operation personnel to be burned or frostbite.
Pipe insulation is widely used in the transmission pipeline network of liquid, gas, and on insulation conveyance conduit, pipe insulation, particularly high-temperature pipe insulation are very important links, and can the success or not in this link be directly connected to this pipeline and normally come into operation.
At present, pipe insulation material generally adopts rock wool, centrifugally glass-wool, silicate, polyurethane foam
,polyethylene etc., their each have their own deficiencies: rock wool density is large, moisture absorption is large, is harmful to the person; Centrifugally glass-wool is perishable; Not resistance to more than the 80 DEG C high temperature of polyurethane foam and polyethylene.On industrial pipeline thermal insulating material is selected, mostly select rock wool or silicate.Pipe insulation method of construction is generally: pipeline rust cleaning, brush anti-corrosive primer, installation thermal insulating material, wrapping glass fiber cloth, outsourcing tin plate or aluminium skin.This heat preserving method is functional, and fireproof performance is good, but water-proof performance is poor, and construction is complicated, the cycle is long, and working life is short.Especially rock wool heat-preservation, once meet water can generate a kind of salt, serious to corrosive pipeline.
If pipeline adopts rock wool heat-preservation outsourcing iron sheet to be difficult to accomplish sealing, after being often newly incubated, only has the time of 2 ~ 3 years, because of rain leakage, just there is heavy corrosion in pipeline external surface, and cannot see from outsourcing iron sheet surface, because this increasing the workload of pipe detection, reduce the working life of pipeline.
In the prior art, also the case using thermal-insulating pipe case insulation is had, but general thermal-insulating pipe case is made up of two and half shells of certain length, the shell internal surface and the conveyance conduit that formed are that face contacts, and heat diffusion area is large, and heat insulation effect is bad, and certain heat insulation effect will be reached, just must increase the thickness of shell, this not only makes troubles to construction, too increases construction cost.
Model utility content
Main purpose of the present utility model is, overcome the deficiency that in prior art, pipe insulation exists, there is provided a kind of for pipe insulation, not only high insulating effect, long service life, cost is low, and construction install convenience, be specially adapted to the thermal insulation apparatus carrying out being incubated protection to the transmission pipeline network of liquid, gas.
The technological scheme that the technical problems to be solved in the utility model is taked is: described thermal insulating apparatus for pipe comprises in pairs and interval fixed cover is located at the support ring on pipeline, described support ring is bearing shell shape, support ring is fixedly installed frame, described frame is provided with thermal insulation coatings layer, described support ring, between pipeline and frame gap-forming have heat storing and heat preserving chamber.
Described support ring two ends are provided with attachment hole, and described paired two support ring jump rings are also located on pipeline by attachment hole fixed cover; Support ring two ends butt-joint clearance is 2-3 millimeter.
Described frame resistant to elevated temperatures organic or inorganic plate or sheet metal are coated on support ring, and described thermal insulation coatings layer adopts spraying or painting method to be arranged on frame, and thermal insulation coatings layer thickness is 1-2 millimeter; Described support ring exotic material is made, and described exotic material is stupalith.
The utility model is owing to frame outer surface being provided with thermal insulation coatings layer and with high temperature resistant (generally all more than the 500 DEG C) support ring that material (as stupalith) is made, making Shell Plate, between pipeline and support ring, interval can be formed with the heat storing and heat preserving chamber in ring body shape.Innovation of the present invention is to utilize still air in the heat storing and heat preserving chamber of the net distribution formed on 300-400 DEG C of high-temperature pipe (as being provided with the petroleum transportation pipeline of heater in pipeline) outer wall at pipeline, particularly temperature and ultrathin thermal insulation coatings as pipe insulation thermal-protective coating, realizes best heat insulation effect; It has that energy-conserving and environment-protective, structure are simple, good airproof performance, heat insulation effect obviously, thermal insulation layer light weight, do not need to fill any heat-insulating heat-preserving material, the advantage of easy construction, not only can meet the requirement of pipeline, special high-temperature pipe insulation; And the overall tightness of thermal insulation apparatus is good, significantly heat bridge effect be can reduce, seepage and corrosion effectively prevented; Dismounting is simultaneously convenient, easy access and maintenance.
