Description
Technical field
The utility model relates to a kind of oil well mouth used heater, especially electromagnetic heating constant temperature control device.
Background technology
When north oilfield recovered the oil winter, because environment temperature is low excessively, well head produced liquid and easily analyses curedly, causes the excessive problem of return pressure.It has not only influenced the output of recovering the oil, and can cause the generation of freezing well when problem is serious, has influenced normal oil producing operation.And existing well head heater is because reasons in structure exists thermal conversion rate extremely low, and it is bigger that heat exchange area needs, and, the problem of the too high phenomenon of local temperature easily takes place, influence oil recovery efficiency.
Summary of the invention
Extremely low in order to solve existing well head heater thermal conversion rate, heat exchange area needs bigger problem.The utility model provides a kind of electromagnetic heating constant temperature control device.It is high that this electromagnetic heating constant temperature control device has thermal conversion rate, and heat exchange area needs features of smaller.
The technical solution of the utility model is: this electromagnetic heating constant temperature control device comprises housing, control cabinet, feed tube, drain pipe and heating inductance coil.Housing has door, control cabinet places above the housing, feed tube and drain pipe place in the housing respectively, feed tube is connected with well head, drain pipe is connected with liquid-transport pipe-line, in parallelly between feed tube and the drain pipe be communicated with 3 standpipes, connect between feed tube and the drain pipe and be communicated with reduced pipe, be equipped with heating inductance coil and temperature pick up on the standpipe, be communicated with flow transmitter and safety valve respectively on feed tube in the housing and the drain pipe, heating inductance coil, temperature pick up link to each other with circuit in the control cabinet respectively by lead with flow transmitter.
The utlity model has following beneficial effect: this electromagnetic heating constant temperature control device is owing to adopt housing that door is arranged, control cabinet places above the housing, feed tube and drain pipe place in the housing respectively, feed tube is connected with well head, drain pipe is connected with liquid-transport pipe-line, in parallelly between feed tube and the drain pipe be communicated with 3 standpipes, connect between feed tube and the drain pipe and be communicated with reduced pipe, be equipped with heating inductance coil and temperature pick up on the standpipe, be communicated with flow transmitter and safety valve respectively on feed tube in the housing and the drain pipe, the heating inductance coil, the structure that temperature pick up and flow transmitter link to each other with circuit in the control cabinet respectively by lead.Utilize circuit control heating inductance coil in the control cabinet, the conversion magnetic field that the heating inductance coil produces makes standpipe produce vortex phenomenon, thereby make standpipe directly produce heat, and heat is directly transferred in the extraction liquid, heat transfer rate is improved greatly, can reach more than 95%, dwindle heat exchange area.It is high that this electromagnetic heating constant temperature control device has thermal conversion rate thus, and heat exchange area needs features of smaller.

Accompanying drawing 1 is the utility model structural representation.
1-housing among the figure, the 2-control cabinet, the 3-feed tube, the 4-drain pipe, 5-heats inductance coil, 6-standpipe, 7-reduced pipe, 8-temperature pick up, 9-flow transmitter, 10-safety valve.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, this electromagnetic heating constant temperature control device comprises housing 1, control cabinet 2, feed tube 3, drain pipe 4 and heating inductance coil 5.Housing 1 has door, inner casing, insulation layer and shell, and the back casing 1 of closing the door forms an airtight incubator, mainly is to prevent scattering and disappearing of temperature, plays the insulation effect in winter.Control cabinet 2 places above the housing 1; at aboveground formation all-in-one; circuit in the control cabinet 2 mainly is that function has to the control of heating: 5 drivings of heating inductance coil, multi-point temp sampling, traffic sampling, temperature control, voltage protection, current protection and limiting temperature protection.Feed tube 3 and drain pipe 4 place respectively in the housing 1, feed tube 3 is connected with well head, drain pipe 4 is connected with liquid-transport pipe-line, in parallelly between feed tube 3 and the drain pipe 4 be communicated with 3 standpipes 6, connect between feed tube 3 and the drain pipe 4 and be communicated with reduced pipe 7, form the oil transportation loop by feed tube 3, drain pipe 4, standpipe 6 and reduced pipe 7.Reduced pipe 7 is exactly that caliber is less than standpipe 6 calibers.Be equipped with heating inductance coil 5 and temperature pick up 8 on the standpipe 6, heating inductance coil 5 has three, is installed on the standpipe 6 of the three seamless steel pipe tubing in oil transportation loop, and each pipeline is installed coil, mainly is that control cabinet drives it extraction liquid is heated.By well liquid in the heating inductance coil 5 heating standpipes 6, temperature pick up 8 has 5, be installed in three inductance coils in, be responsible for the temperature sampling to each heating position, and transfer of data circuit in the control cabinet 2, and heating-up temperature controlled, two other temperature pick up 8 is installed on the place, extraction liquid access of feed tube 3 and drain pipe 4, detected temperatures state.Be communicated with flow transmitter 9 and safety valve 10 respectively on feed tube 3 in the housing 1 and the drain pipe 4, whether flow transmitter 9 major functions are to detect to have liquid to flow through, if having liquid to flow through then carry out heating operation, otherwise, stop heating operation.When avoiding no liquid to pass through, heater is still worked.Cause heating-up temperature too high, when producing excessive pressure, safety valve 10 is opened release pressures automatically in that pipe temperature is too high.Heating inductance coil 5, temperature pick up 8 and flow transmitter 9 link to each other with circuit in the control cabinet 2 respectively by lead.
This electromagnetic heating constant temperature control device is brought up to the temperature of extraction liquid and is analysed more than the cured point.The product principle is that the power frequency supply with 50HZ is reverse into high frequency electric source more than the 20KHZ and acts on and produce eddy current on the oil transportation loop and make the pipeline self-heating, its thermal efficiency is near 100%, simultaneously because the effect of electromagnetic field of high frequency, slackened the adhesion of metal ion in the liquid greatly, can make metal ions such as calcium in the liquid, sodium, magnesium arrange in order unsuitable in conjunction with, incrustation scale can be do not formed, therefore interchange of heat can be do not influenced.And circuit does not contact the not danger that can leak electricity or catch fire fully with media such as water.Simultaneously the electromagnetism mode of heating can reduce the adhesion of former oil molecule greatly, makes viscous crude carry at a lower temperature and can not condense.Heating inductance coil 5 adopts no thermal source induction heating technique, no high temperature, and leakproof is safest explosion-proof electrical heating product.Simultaneously because adopting the frequency of State Environmental Protection Administration's regulation, so harmless.Inductor can directly be attached on the oil pipeline insulation layer during use, can accomplish Fast Installation and need not stop production.
This electromagnetic heating constant temperature control device heat transfer rate is brought up to more than 95% by 30～40%, and heat transfer rate improves greatly.
