Description

The cooling heat insulating construction at high temperature pipe network horizontal pipe top

Technical field

The utility model is related to pipe insulation field, specifically a kind of cooling at high temperature pipe network horizontal pipe top Heat insulating construction.

Background technology

Heat supply pipeline is a kind of to be exclusively used in conveying the pipeline of the gas with uniform temperature or liquid.High temperature pipe network be by Multiple heat supply pipelines assemble and form, and need, to the gas in course of conveying or liquid insulating, to reduce and even avoid heat loss, To adapt to production operation needs or to ensure that conveying is normal, it is common in industrial production (as petroleum pipeline, chemical pipeline etc.) and life In (hot duct etc.).In prior art, during the defeated heat of pipeline, how insulation is thermally shielded using asbestos, rubber-plastic sponge etc..But defeated heat During, because hot-air readily flows to the top of horizontally disposed pipeline so that the upside temperature of pipeline is compared to pipeline two The temperature of side and bottom is high more, the temperature difference (the hereinafter referred to as temperature difference) therefore between heat supply pipeline top and other positions Larger, and then lead to the thermal losses at pipeline top to increase.Excessive thermal losses not only affects the defeated thermal process of heat supply pipeline, also can Increase the fuel cost of enterprise.And the heat insulation layer thickness in existing heat supply pipeline is uniformly arranged it is difficult to stop heat from scattering and disappearing.

Content of the invention

For overcoming the deficiencies in the prior art, the utility model provides a kind of middle height that can equalize pipeline each position temperature difference The cooling heat insulating construction at warm pipe network horizontal pipe top, can effectively reduce the temperature difference at each position of pipeline, reduce thermal losses.

For achieving the above object, the technical solution adopted in the utility model is: the fall at high temperature pipe network horizontal pipe top Warm heat insulating construction, including the internal insulation being close to pipeline outer wall setting and outer heat insulation layer, the internal insulation at pipeline top is exhausted with outer It is equipped with least one of which cap layer between thermosphere.The cross section of described cap layer be arch-shaped, its arc long side side outwardly, arc Fit inwardly and with internal insulation outer wall in shape minor face side, non-equidistant placement between the described long side of arc and outer heat insulation layer.

In said structure, horizontal pipe means the pipeline being horizontally disposed with and using.In on the upside of horizontally disposed pipeline Cap layer is set up, cap layer is made using heat-insulating material, by uneven eccentric adiabatic knot between heat insulation layer and outer heat insulation layer Structure, strengthens the insulation effect at horizontal pipe top, effectively reduces the heat being transferred on the upside of pipeline, thus reducing horizontal tube The temperature difference between the temperature at road top and other positions, reduces pipeline thermal losses.

Further, described cap layer is made using heat-insulating materials such as the ultralight alumina silicate of long filament or glass wool material.

Further, the thickness of described cap layer is 10mm ~ 80mm.The thickness of cap layer can be according to the diameter of actual pipeline Size and the quantitative design of cap layer.

Further, described cap layer can be also fan-like pattern or arch.

Further, the outer wall of described cap layer is bonded with one layer of reflecting material.Described reflecting material can be in cap layer Form one layer of reflecting layer, for reflecting heat radiation, reduce the heat to the transmission of pipeline top.

Further, described cap layer covers the circular arc of the top half 1/2nd of internal insulation cross section.

The utility model has the beneficial effect that: the utility model is additionally arranged with guarantor between outer heat insulation layer and internal insulation The cap layer of gentle reflection function, effectively reduces the heat of the transmission on the upside of pipeline, reduces pipeline top heat, has equalized pipe Temperature between each position in road, thus substantially reducing the temperature difference between each position of pipeline, reduces thermal losses.

And, the utility model structure is simple, it is easy to processing, produces and later period maintenance, improving pipe insulation performance Also production cost is maintained relatively low level simultaneously, there is certain economic worth and practical value.

Specific embodiment

Embodiment one: as shown in figure 1, the present embodiment is close to horizontal pipe outer wall is sequentially provided with internal insulation 2 and outer thermal insulation Layer 4, internal insulation 2 is close to the setting of pipeline body 1 outer wall, and outer thermal insulation layer is close to inner insulating layer setting.In pipeline top absolutely It is provided with cap layer 1 between thermosphere 2 and outer heat insulation layer 4.The cross section of cap layer 1 is arch-shaped, and cap layer is set outside In heat insulation layer 4.

In conjunction with shown in Fig. 2, its arc long side side outwardly and with outer heat insulation layer 4 non-equidistant placement, arc minor face side court Interior and with fit internal insulation 2 outer wall setting, formed cap layer 1 cover internal insulation 2, set exhausted in outer heat insulation layer 4 Heat structure.Cap layer 1 that non-equidistant placement and heat-insulating material are formed is effective completely cut off the internal insulation 2 at horizontal pipe top with Heat transfer between outer heat insulation layer 4, it is to avoid transmit to the both sides of pipeline and bottom on the upside of the heat transfer in pipeline to pipeline, Reducing the temperature at pipeline top, thus equalizing the temperature between each position of pipeline, the temperature difference reducing between each position of pipeline, reducing Thermal losses, and the service life of heat supply pipeline is extended to 10 years.
