Description
Technical field
The utility model relates to petroleum pipeline heating device technology area, provides a kind of internally heated type heating equipment.
Background technique
Oil is in oil recovery process, because oil is too high containing cured amount, carry oil concentration large, often cause oil transport pipeline oil transportation difficulty, especially in cold season, heating on petroleum pipeline is needed to solve the problem of oil transportation difficulty, existing electric heater for petroleum pipeline is generally be arranged on petroleum pipeline outer wall, and petroleum pipeline is in order to be incubated, often petroleum pipeline many employings inner core, thermal insulation layer and urceolus, although the setting of thermal insulation layer can reduce scattering and disappearing of the interior oil heat of pipe, increase the difficulty come the petroleum in pipe simultaneously.
Summary of the invention
In order to address the aforementioned drawbacks, the purpose of this utility model is to provide a kind of internally heated type heating equipment.
The utility model is by the following technical solutions to achieve these goals:
A kind of internally heated type heating equipment, comprises inner core, thermal insulation layer and urceolus, urceolus is provided with screw, inner core is provided with heating chamber, be provided with electric heating wire in heating chamber, heating chamber extends along inner diameter of steel flue direction, inner core and thermal insulation layer is provided with the through hole of the electrode for drawing electric heating wire.Use and by bolt, heating equipment is fixed between two between flanged ends.Connected by the electrode of electric heating wire, electric heating wire work, heating, the heat that electric heating wire gives out by the heating chamber extended along inner diameter of steel flue direction transmits the oil in a petroleum pipeline.
In technique scheme, described inner core adopts aluminium, and the heat transfer performance of aluminium is superior, effectively the heat that electric heating wire produces can be passed to the oil in pipe, improve heat transference efficiency, add the utilization to heat energy.
In technique scheme, described heating chamber is at least 2, its annular on inner core is uniform, adopt the design of heating cavity can increase effective heating area of oil, it should be noted that if heating chamber quantity is too much, that face can result in blockage to oil, reduce the flow of oil, the heating chamber therefore arranging suitable quantity is very important, and preferred heating chamber number is 4-6.
In technique scheme, thermal insulation layer adopts glass wool, and the design adopting thermal insulation layer is to better utilize heat energy, and the heat that the heating wire that thermal insulation layer is avoided produces passes to urceolus by heat trnasfer, thus causes heat loss, increases the utilization ratio of heat.
In sum, the utility model hinge structure, has following beneficial effect:
1, adopt the mode of interior heating, avoid transmission to the heating of transport pipe outer wall, then by heat trnasfer, the oil process middle tube body heat trnasfer thermal loss transferred heat in pipe is high, the defect that heating effect is bad.
2, adopt heat insulation layer structure, avoid scattering and disappearing of the heat of electric heating wire generation, provide the utilization ratio of the energy.
