Abstract
The utility model provides an extension-type heat-insulating device which comprises a protective layer, an insulating layer and a sleeve layer, wherein the sleeve layer is coated on the outer surface of an insulated pipeline or tank body and is concentric with the pipeline or the tank body; the insulating layer is wrapped outside the sleeve layer; the protective layer is adhered on the surface of the insulating layer; and the sleeve layer is hollow. According to the utility model, a sleeve is additionally arranged, and an air layer is added between the sleeve and the insulated pipeline or tank body; and as the air is classified as a bad conductor, the heat transfer resistance is increased under condition of not increasing the thickness of the insulating layer, as a result, the excessive insulating investment for the pipeline and tank is solved, the heat dissipation loss is greatly reduced, and the energy source consumption is also reduced.
Description
Technical field
The utility model relates to a kind of bushing type thermal insulation apparatus, belongs to the heat-preserving equipment technical field.
Background technique
Steam needs long distance to carry or storage as industrial major impetus.Because the existence of the temperature difference has caused the heat exchange between conveyance conduit or storage tank and the ambient air.In order to reduce thermal loss, present common way is at pipeline or the outside thermal insulation layer that increases of tank body, thereby reduces thermal loss by increasing thermal resistance.Since be subject to the impact of Economy, the impossible infinite thickness of insulation layer thickness, and therefore, under the relatively high insulation layer thickness condition of Economy, thermal loss is still larger.Develop new thermal insulation apparatus, for reducing radiation loss, energy saving is significant.
Along with the development of material technology, heat insulating material more and more obtains people's attention.And for utilizing heat transfer principle, the domestic almost nobody of research Novel sleeve type thermal insulation apparatus studies.
The model utility content
The purpose of this utility model provides a kind of bushing type thermal insulation apparatus, with the increase heat transfer resistance, thereby reduces radiation loss.
The utility model is realized by following technical proposal: a kind of bushing type thermal insulation apparatus; comprise protective layer, thermal insulation layer and casing layer; described casing layer is wrapped in pipeline or the tank body outer surface and concentric of insulation; the casing layer outside is wrapped up by thermal insulation layer; insulation layer surface is adhered to protective layer, and wherein casing layer is hollow.
Described casing layer thickness is 0.5～2mm.
Described thermal insulation layer adopts conventional thermal insulating material to make.
Described protective layer adopts conventional waterproof and dampproof material to make.
Because air belongs to poor conductor, so the casing layer of hollow has increased heat transfer resistance, and then has reduced radiation loss, has improved heat insulation effect.This bushing type thermal insulation apparatus can extensive use and pipeline and the tank body of conveying and storage hot fluid.
The advantage that the utlity model has and effect:
(1) by increasing sleeve pipe, pipeline or tank body in sleeve pipe and insulation have increased one deck air layer, because air belongs to poor conductor, in the situation that do not increase insulation layer thickness, increased heat transfer resistance, other conditions are constant, when casing layer Air thickness is 1mm, the device the coefficient of heat transfer be the tradition (not having casing layer) thermal insulation layer heat-transfer coefficient 0.3%, heat-transfer effect obviously descends;
(2) solve the excessive problem of pipeline or tank body insulation investment, can significantly reduce radiation loss, reduced energy consumption.
