Abstract
An electromagnetic heating pipe used in crude oil gathering line for heating crude oil or water locally during delivery comprises a flange disc (1), a temperature measuring hole (2), a cast aluminum sleeve (3), a coil winding (4), and a steel pipe (5). The utility model is characterized in that the flange disc (1) is connected with the cast aluminum sleeve (3), the coil winding (4) is wound on the steel pipe (5), and the temperature measuring hole (2) is formed on the steel pipe (5). The heating body is the pipeline and can heat oil/gas delivered therein directly to overcome problem of low heating efficiency by indirectly heating with water-sleeved heating furnace or electric heating bag. The coil and the heating media are isolated completely to ensure safety of the device during application. Temperature rises rapidly because of the high heating speed, thereby achieving simultaneous heating from the inner side to the outer side.
Description
Technical field
The utility model is the device that in the petroleum pipeline course of conveying crude oil or water is carried out local heating, specifically, is a kind of crude oil transmission pipeline electromagnetism heating pipe.
Background technique
The crude oil in oil well well site is in course of conveying, because the reduction of temperature makes crude oil solidify coking, can't carry out proper set and fail.Existing crude oil local heating equipment can not satisfy the requirement of use:
(1) for barreler, usually use water batch heater to heat, this apparatus structure complexity, mainly by water jacket, fire tube, nozzles, boiling tube and walk oil coil five parts and form, adopt oil coil and be immersed in indirect heating method in the water jacket, waste energy befouling environment, working strength of workers is big during operation, not manageability.
(2) for stripper well, generally use the electric heating bag heating, the thermal efficiency of this device has only 20%.
(3) two kinds of Unit Installation are all very complicated.
By retrieval, at present in China oil field, this heating equipment belongs to initiative.
Summary of the invention
The purpose of this utility model is: it is pipeline itself that a kind of heater is provided, and the oil gas of wherein carrying is directly heated, thereby effectively overcome water batch heater, the electric heating bag indirect heating, the drawback that the thermal efficiency is low; Coil is isolated fully with the heating medium, the Security during the equipment that guaranteed uses; Temperature raises rapidly, and promptly rate of heating is fast, from inside to outside the crude oil transmission pipeline electromagnetism heating pipe that heats up synchronously.
The utility model is achieved in that
Comprise flange plate 1, temperature measuring hole 2, cast aluminium overcoat 3, coil winding 4, steel pipe 5, flange plate 1 is connected on the cast aluminium overcoat 3, is wound with coil winding 4 on the steel pipe 5, and steel pipe 5 is provided with temperature measuring hole 2.
The utility model also adopts following technological scheme:
Coil winding 4 is continuous double wrap, and its shape cooperates with steel pipe 5 diameters.
Flange plate 1 directly links to each other with transport pipe.
Lead enters from coil winding 4 one ends, draws from the homonymy the other end.
The spacing of coil winding 4 and steel pipe 5 is less than 10mm.
The spacing of coil winding 4 and cast aluminium overcoat 3 is less than 20mm.
The utility model has the advantages of and be:
Temperature raises rapidly, and promptly rate of heating is fast, heats up synchronously from inside to outside.Show according to relevant data, make same medium rise to uniform temp, the electromagnetism heating is economized on electricity more than 40% than resistance heating.Safe and reliable, coil is isolated fully with the heating medium, the Security during the equipment that guaranteed uses.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, comprise flange plate 1, temperature measuring hole 2, cast aluminium overcoat 3, coil winding 4, steel pipe 5, flange plate 1 is connected on the cast aluminium overcoat 3, is wound with coil winding 4 on the steel pipe 5, and steel pipe 5 is provided with temperature measuring hole 2.Coil winding 4 is continuous double wrap, and its shape cooperates with steel pipe 5 diameters.Flange plate 1 directly links to each other with transport pipe.Lead enters from coil winding 4 one ends, draws from the homonymy the other end, and the spacing of coil winding 4 and steel pipe 5 is less than 10mm, and the spacing of coil winding 4 and cast aluminium overcoat 3 is less than 20mm, and temperature measuring hole 2 reaches steel pipe 5 inside.Steel pipe 5 is a magnet case, is heater, and transported material obtains temperature increase from wherein passing through, and outer cast aluminium plays the effect of insulation, heat conduction, sheath, and winding coil is the copper paint envelope curve.
(1) temperature raises rapidly, and promptly rate of heating is fast, heats up synchronously from inside to outside.Show according to relevant data, make same medium rise to uniform temp, the electromagnetism heating is economized on electricity more than 40% than resistance heating.
Its formula is as follows:
A＝K·C·Q·ΔT
Wherein, K is the electromagnetic conversion coefficient, generally gets 0.64; C is a thermal conductivity, and water is 1, and oil is 0.475; Q is a rate-of flow, and unit is m
3/ h; Δ T is the temperature difference.
(2) safe and reliable
Coil is isolated fully with the heating medium, the Security during the equipment that guaranteed uses.
