Description
The utility model belongs to the improvement of oil pipeline structure, relates to the oil pipeline technical field of heating.
In the oil transportation process that oil field shaft mouth recovers the oil, because well head oil temperature is lower, viscosity of crude is thicker, often makes the petroleum pipeline wall wax deposition, causes pipeline obstruction, has had a strong impact on normal oil producing operation.To this existing solution is to adopt to be added with sleeve pipe outside petroleum pipeline, accompanies heat to come diluent crude oil by hot water or steam to petroleum pipeline, and crude oil is flowed out swimmingly.Though this way has solved the tubing wax problem to a certain extent, this companion's heat needs to use hot water or steam boiler system, its complex structure, and equipment investment is quite big, also needs personnel's monitoring on duty during use, thereby causes whole service cost height.In the burn crude boiler technology,, also need petroleum pipeline to be accompanied hot diluent crude oil in addition, boiler can normal combustion be used with hot water or steam because the viscosity height of crude oil causes oil spout not smooth.The weak point of this companion's heat also has, and it requires high temperature resistant, withstand voltage, the corrosion-resistant and sealing of heat tracing pipe palpus, therefore the cost of manufacture of heat tracing pipe itself is increased, and thermal source carries the loss in the way to make thermal efficiency reduction; In addition, in order to ensure the uninterrupted of oil transportation, this tracing system also must be equipped with stand-by boiler and standby steam heating boiler except that working boiler and steam heating boiler are installed, and uses when safeguarding to substitute boiler, and this has just increased equipment investment.At present, use the technology of Electric radiant Heating Film heating quite ripe, because its thermal efficiency height, cost of manufacture is low, safe and reliable, has obtained extensive use in many technical fields.
The purpose of this utility model is to provide a kind of oil transportation heat tracing pipe with the Electric radiant Heating Film heating, and it can realize not having pressure operation and control automatically, has advantage simple in structure, that the thermal efficiency is high, safe and reliable.
The technical solution of the utility model is achieved in that designed oil transportation heat tracing pipe is made up of petroleum pipeline and outer tube, there is adpting flange at the two ends of petroleum pipeline, its design feature is: be coated with insulating layer in the petroleum pipeline outer wall surface, be coated with the Electric radiant Heating Film zone of heating on the insulating layer, the switch board outside being connected to electrode on the Electric radiant Heating Film and managing is connected; Be filled with insulating heat insulating material in the cavity between petroleum pipeline and outer tube, be provided with seal plug at the cavity two ends.Feature of the present utility model also is, also can be fixed with temperature pick up by petroleum pipeline one side in the cavity between petroleum pipeline and outer tube, and its holding wire is connected in the outer switch board of pipe.
From said structure as can be seen: because the designed oil transportation heat tracing pipe of the utility model is manufactured with the Electric radiant Heating Film heating arrangement at the petroleum pipeline outer wall; make heat tracing pipe constitute the electric heating device of direct conduction-type; and fill insulating heat insulating material in the space between petroleum pipeline and outer tube; not only play insulation; improve the effect of the thermal efficiency; but also formed double-deck protective effect with outer tube; make the designed heat tracing pipe of the utility model when being used for the oil field oil recovery; can significantly reduce the equipment investment of tracing system; and energy conservation; realize unattended automatic control, reduce well head oil transportation running cost significantly.And be used for the burn crude boiler technology reform, and use the designed oil transportation heat tracing pipe of the utility model also can realize not having the electric tracing of pressure operation, compared with prior art, it has the advantage of thermal efficiency height, safe and reliable, small investment; The utility model also has advantage simple in structure, easy to maintenance, that cost of manufacture is low in addition.
Accompanying drawing is the structural representation of the designed oil transportation heat tracing pipe of the utility model, and in the drawings, 1 is outer tube, and 2 is petroleum pipeline, and 3 is insulating layer, and 4 is the Electric radiant Heating Film zone of heating, and 5 is the thermal insulating layer, and 6 is temperature pick up, and 7 is seal plug, and 8 is adpting flange.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Referring to accompanying drawing, the designed oil transportation heat tracing pipe of the utility model is to be with sleeve pipe outside petroleum pipeline, the two ends of petroleum pipeline are provided with adpting flange, be coated with temperature-resistant insulation layer in the petroleum pipeline outer wall surface, the temperature-resistant insulation layer such as organic or organic class of fluorine such as silicon, on insulating layer, be coated with the Electric radiant Heating Film zone of heating, described Electric radiant Heating Film can be that graphite powder, carbon powder or other conduction powder are the mixed product of conductive phase and adhesive, it also can be the tin ash conducting film that mixes, these all belong to prior art, do not repeat them here; For reducing thermal loss, improve the thermal efficiency, the cavity between petroleum pipeline and the outer tube is filled with insulating heat insulating material, all can as fireproof heat insulating cotton, insulating powder etc.; Two-port at the outer tube cavity is provided with seal plug, and plug and petroleum pipeline adopt spot welding get final product with the seam that is connected between sleeve pipe, and as if heat tracing pipe requirement of explosion proof are arranged, and then seal request is tight, and its connection can adopt means such as seal welding to be sealed; Heating-up temperature for monitoring and collection petroleum pipeline, guarantee the unimpeded and safe operation of oil transportation, in cavity, be set with temperature pick up near petroleum pipeline one side, temperature pick up can be used electroheat pair, realization such as RTD, optical fiber, its signal link is connected in the outer switch board of pipe with the electrode wires of Electric radiant Heating Film, for adapting to different needs, power supply junction outside heat tracing pipe is provided with switch board, can monitor and regulate heating-up temperature.It is the control power switch that switch board mainly acts on, wherein temperature control can be adopted the circuit structure of similar existing electric water heater, also can adopt the similar structures of robot control system(RCS) among CNZL95200637.5 and the CNZL96236149.6 (controlling electric heating equipment automatically), this is that ordinary skill can be finished.
The oil transportation heat tracing pipe that the utility model is designed is that the adpting flange with two ends is connected in the oil pipeline, and it can use by single tube, also can the multitube series connection use.When being used for oil field operation, can be according to the specific requirement of oil field oil pipeline, spacing is liftoff to be provided with installation, and the field preferably is embedded in underground, to prevent stolen or artificial damage.Electric radiant Heating Film is connected with the switch board power supply, during use, connects power supply and monitoring system, this moment, Electric radiant Heating Film converted electrical energy into heat energy, and petroleum pipeline is accompanied heat, when crude oil when the oil pipe inner chamber flows through by heated at constant temperature, thereby reach the purpose of diluent crude oil, guarantee that oil producing operation carries out smoothly.Be used for the burn crude boiler technology reform, heat is accompanied at the petroleum pipeline place that heat tracing pipe directly is installed on boiler.
