Technical field
The utility model belongs to electric heating equipment technical field, particularly a kind of petroleum electrcal heating appts of well head.
Background technique
In oil extraction in oil field field, along with fast development and the technological progress of petroleum industry, more and more higher to the technical requirements of the oil electric heating equipment of its well head.Due to the impact of the gentle viscosity of crude of being bullied, while much recovering the oil petroleum pipeline conveying crude oil, need heating.And at present petroleum pipeline Electric heating appliance used, because reasons in structure exists the low and high problem of electric energy loss of the thermal efficiency, causes cost for oil production rising ，Gei enterprise to increase serious burden.
When oil extraction operation ambient temperature is too low, well head generation liquid is easily analysed cured, causes the excessive problem of return pressure.It has not only affected the output of recovering the oil, and when problem is serious, can cause the generation of freezing well, has affected normal oil producing operation.And existing hole top heater is because reasons in structure exists thermal conversion rate extremely low, heat exchange area needs larger, and, easily there is the problem of the too high phenomenon of local temperature, affect oil recovery efficiency.
Model utility content
The purpose of this utility model is to solve the low and high problem of electric energy loss of the existing oil transmission pipeline electric heating device thermal efficiency.
The electromagnetic heater that the utility model provides, simple and practical, quick heating, the thermal efficiency is high, be heated evenly, can heat the crude oil of various different qualities, reduce stickiness, reduce oil flow resistance, make pipeline smooth and easy, adapt to especially the electric heating of the oil and gas of well head.Electric heating production run comprehensive cost is low, and the life-span is long, and it is high that this high-efficiency electromagnetic heating equipment has the thermal efficiency, and electric energy loss is low, simple in structure and safe and reliable feature.
This well head electromagnetic heater of the present utility model, by heating casing 1 and control cabinet 6, formed, wherein heat that casing 1 comprises thermal insulation layer 2, oil pipe 9, enters to manage night 10, drain pipe 11 and electromagnetic coil inductor 5, in casing 1, also comprise entrance temperature inductor 3, outlet temperature inductor 4 and pressure transducer 12, control cabinet 6 comprises display screen 7 and adjusting button 8, and above-mentioned electromagnetic coil inductor 5, inlet temperature inductor 3, outlet temperature inductor 4 and pressure transducer 12 are all connected with circuit in control cabinet by wire.
In control cabinet 6 in the utility model, have adjusting button, these regulate button to comprise switch button, temperature adjustment buttons and power adjustments button.
The utlity model has following beneficial effect:
Simple and reasonable and compact, easy to use and safe and reliable, utilize circuit in control box to control heating inductance coil, the conversion magnetic field that heating inductance coil produces directly produces heat, the directly working surface heating to oil pipe, heat transfer rate can reach more than 92%, and heating time is short, and the thermal efficiency is high, electric energy loss is low, temperature control is accurate, and safety coefficient is high, and later maintenance amount is little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model:
Wherein: 1 heating casing; 2 thermal insulation layers; 3 inlet temperature inductors; 4 outlet temperature inductors; 5 electromagnetic coil inductors; 6 control cabinets; 7 display screens; 8 regulate button; 9 oil pipes; 10 enter pipe at night; 11 drain pipes; 12 pressure transducers.
Embodiment
Below by specific embodiment, and by reference to the accompanying drawings the utility model is described in further detail.
As shown in Figure 1, well head electromagnetic heater of the present utility model is by heating casing 1 and control cabinet 6 forms, and wherein heats that casing 1 comprises thermal insulation layer 2, oil pipe 9, enters to manage night 10, drain pipe 11 and electromagnetic coil inductor 5.Oil pipe 9 is 2 circle spiral coil settings in heating casing 1.
In heating casing 1, oil pipe 9 is wound around by the electromagnetic coil of segmented.Oil pipe 9 in heating casing 1 is at oil pipe inlet inlet porting temperature inductor 3, in the outlet port of oil pipe 9, be provided with outlet temperature inductor 4, outlet port at oil pipe 9 is also provided with pressure transducer 12, the object of this setting is exactly when the excess Temperature of oil pipe pipeline, can produce excessive pressure, sensor 12 is by discovery and start safety valve release pressure.
The inwall of heating casing 6 has thermal insulation layer 2, and this thermal insulation layer can adopt refractory material, also can adopt heat-preservation cotton, and the utility model adopts refractory material.
Can be by display screen 7 showing temperature states in control cabinet 6, by comprising that adjusting button that switch button, temperature adjustment buttons and power adjustments button form controls whole Electromagnetic Heating and work.The utility model in use, is first connected general power, opens the switch on control cabinet 6, sets heating equipment outlet temperature boundary, regulates temperature button, selects required corresponding power, can provide at any time the temperature of heating equipment outlet liquid on temperature display 7.Can, according to going out liquid temp, carry out corresponding power adjustment.
Electromagnetic Heating mode can reduce the combination force of former oil molecule greatly, makes viscous crude carry at a lower temperature and can not condense.In the specific Environmental Conditions in oil field, use this system greatly to save electric energy, reduce production costs, improve science and technology in enterprise content, by calculating, contrast, use this system to compare with traditional mode of heating to estimate and can economize on electricity more than 50%, it is huge bringing thus energy-saving effect.
In sum; although the utility model discloses preferred embodiment as above; but can not be in order to conduct to restriction of the present utility model; those skilled in the art is not within departing from spirit and scope of the present utility model; any change and the modification made, all should be considered as not exceeding the scope that the utility model claims are protected.
