Abstract
The utility model relates to a heat preservation layer which shields the radiant heat and the convection heat and belongs to a heat preservation structure. The heat preservation layer is characterized in that: the heat preservation layer, a high-temperature shielding layer, the heat preservation layer, a low-temperature shielding layer, the heat preservation layer and a galvanization thin steel plate are arranged outside an insulated body in sequence. Ventilation holes are arranged on the high-temperature shielding layer and the low-temperature shielding layer. The high-temperature shielding layer adopts a stainless steel thin steel plate and the low-temperature shielding layer adopts aluminum foil. The two materials of the stainless steel thin steel plate and the aluminum foil all have strong light reflection capabilities and are capable of shielding the heat radiation, and the two materials are all compact materials and are capable of shielding the heat convection. The heat preservation layer of the utility model for shielding the radiant heat and the convection heat has the advantages of reasonable design, simple structure, effective prevention of the radiant heat and the convection heat and good heat preservation effect.
Description
Technical field
The utility model belongs to insulating structure, particularly relates to the thermal insulation layer of a kind of radiation-screening heat and convection heat.
Background technique
Present petrochemical enterprise, a large amount of equipment and pipeline insulating structures that use are the outer surface coating thermal insulating materials at equipment and pipeline, the outer surface of thermal insulating material is protected with galvanized sheet metal, sees Fig. 1.Among Fig. 1: 1 equipment and pipeline housing; 2 thermal insulation layers; 3 galvanized sheet metals.This structure is utilized the lower characteristics of thermal insulating material heat-conducting system, realizes the purpose that is incubated by retardance transmission of heat, and the insulation that this structure is used for not high equipment of temperature and pipeline is effective.But the occasion heat insulation effect that is used for high-temperature service and pipeline is bad, though the thermal insulation layer of design is very thick, the temperature of thermal insulation layer outer surface is still higher, and thermal loss is big, and energy waste is big.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of radiation-screening heat of high insulating effect and the thermal insulation layer of convection heat are provided.
The thermal insulation layer of radiation-screening heat of the present utility model and convection heat is to have coated thermal insulation layer, galvanized sheet metal successively at the warmed body outer wall, is provided with screen layer in thermal insulation layer.
Further improve as the utility model, in thermal insulation layer, be provided with to spacing high temperature screen layer and low temperature barrier.
Further improve as the utility model, on high temperature screen layer and low temperature barrier, have vent.
The design uses the basic principle of heat transfer theory, in traditional thermal insulation layer the inside, has added the screen layer of radiation heat and convection heat.The high temperature screen layer adopts stainless steel book steel plate, and low temperature barrier adopts aluminium foil.Two kinds of materials all have very strong luminous reflectanc, can shield thermal radiation.Two kinds of materials all are the compactness materials, can shield thermoconvection.The consumption of two kinds of materials is few, and price is low, and energy-saving effect is remarkable.
When high-temperature service and pipeline heated up, the air expanded by heating in the thermal insulating material needed to overflow.When high-temperature service and pipeline cooling, the air cooling in the thermal insulating material is shunk and need be covered.For making things convenient for air in the thermal insulating material owing to flowing that the expansion of volume and shrinkage take place, have breeder tube on the material of the two-layer high temperature screen layer that present technique adopts, avoid damaging screen layer.The ratio of the area of breeder tube is very little, and is very little by the convection heat losses of aperture.
The thermal insulation layer of radiation-screening of the present utility model heat and convection heat is reasonable in design, simple in structure, stoped radiation heat and convection heat, high insulating effect effectively.
