Abstract
The utility model provides a flat arc heat exchange tube for accompanying defeated oil pipe of heat, relates to defeated oil pipe. Be equipped with flat arc tube, flat arc tube's both ends are equipped with respectively to be traded the hot working medium import and trades the hot working medium export, flat arc tube's cross section is 12 or 14 arcs, convex camber equate with the camber of defeated oil pipe surface to flat arc tube laminates in defeated oil pipe's surface, forms the complete coated pipe body. Because formation is equal the contact of camber face between flat arc tube and the defeated oil pipe body, flat arc heat transfer area under control separates the drain passageway that the passageway is used for making hot working medium. Consequently, the heating device to the defeated oil pipe of prior art companion heat improves to the flat arc heat exchange tube of body bent plane contact replaces the steam pipe of single formation and the ribbon heater that consumes clean energy, realizes the technical requirement of heat pump heat source to system hot working medium 's the defeated oil pipe of the flat heat exchange tube heat tracing pipe of nice and warm arc companion heat through the interface assembly, and the thermal efficiency is high, the energy saving.
Description
Technical field
This utility model relates to petroleum pipeline, especially relates to a kind of flat arc heat exchanger tube for heat tracing petroleum pipeline.
Background technology
Heat tracing petroleum pipeline heat tracing form disclosed in prior art has two kinds: one to be steam pipe heat tracing, and its structure generally comprises body and is attached to the steam-heating pipe below body, and steam pipe utilizes and flows through steam realization to the oily heat tracing in pipe.But, the pipe that the steam pipe of this structure is single form is arranged.Being that cambered surface contacts with the line style of cambered surface between steam pipe with body, its contact area is only small, and the oily heat tracing of body weight can only be leaned on narrow and small the contacting of cambered surface and cambered surface to conduct heat by heat-exchange working medium, therefore the thermal efficiency is very low.Two is ribbon heater heat tracing, and ribbon heater utilizes electric current to flow through and self produces heat realization to the oily heat tracing in body.But, ribbon heater has the characteristic that power attenuation is congenital, is unfavorable for long-time stability and the reliability of petroleum pipeline heat tracing.And ribbon heater is to make use of valuable clean energy resource electric energy to realize its low-temperature heat, from the waste in prior art condition of the energy-saving significance resource.
The open a kind of heat exchanger of oil transport pipeline of Chinese patent CN2473442Y, including housing, it is positioned at the petroleum pipeline of housing, it is characterized in that: in housing, the outer wall of petroleum pipeline is coated with heater, its structure is: be coated with the ring packing interlayer made with Heat Conduction Material in petroleum pipeline outside wall surface, it is filled with heat-conducting medium in ring packing interlayer, ring packing interlayer outer wall is coated with inner insulating layer and external insulation layer, in, Electric radiant Heating Film is accompanied between external insulation layer, Electric radiant Heating Film is connected with power supply by going between, this device has thermal efficiency height, quick heating, energy-conservation, long service life, load and unload advantage easy to maintenance.
Summary of the invention
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that the thermal efficiency is high, saves a kind of flat arc heat exchanger tube for heat tracing petroleum pipeline of the energy.
This utility model is provided with flat arc pipe, flat arc pipe be respectively arranged at two ends with heat-exchange working medium import and heat-exchange working medium outlet, the cross section of described flat arc pipe is 1/2 or 1/4 circular arc, the curvature of described circular arc is equal to the curvature of petroleum pipeline outer surface, so that flat arc pipe fits in the outer surface of petroleum pipeline, form complete cladding body.
Can being provided with rib in described flat arc pipe, described rib can adopt rib plate, rib pipe or rib bar etc., for increasing the body temperature of petroleum pipeline；It addition, separate heat-exchange working medium for generation to flow through passage.
Contacting owing to forming equivalent curvature surface between flat arc pipe and petroleum pipeline body, flat arc heat exchanger tube separates passage for heating the liquid-conveying ducts of working medium.Therefore the heater of prior art heat tracing petroleum pipeline is improved by this utility model, replace the steam pipe being unitarily formed and the ribbon heater consuming clean energy resource with the flat arc heat exchanger tube of body song plane contact, realized the technology requirement of source heat pump heat heat and the arc flat heat exchanger tube heat tracing pipe heat tracing petroleum pipeline to heating working medium by interface assembly.And the thermal efficiency is high, save the energy.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, this utility model embodiment is provided with flat arc pipe 2, flat arc pipe 2 be respectively arranged at two ends with heat-exchange working medium import and heat-exchange working medium outlet, the cross section of described flat arc pipe 2 is 1/2 or 1/4 circular arc, the curvature of described circular arc is equal to the curvature of petroleum pipeline 1 outer surface, so that flat arc pipe 2 fits in the outer surface of petroleum pipeline 1, form complete cladding body.
Can being provided with rib 3 in described flat arc pipe 2, described rib 3 can adopt rib plate, rib pipe or rib bar etc., for increasing the body temperature of petroleum pipeline 1；It addition, separate heat-exchange working medium for generation to flow through passage.
