Description

Infrared, induction oil electric heater

The utility model relates to a kind of oil electric heater unit, specifically is a kind of infrared, induction oil electric heater.

In the production of recovering the oil, for those high wax oils, viscous crude, production ratio is difficulty at present, because these oil viscosities are big, mobile poor, be difficult to from oil well, extract, influence output, a large amount of consumes energy are in order to solve this difficult problem, the employing steam heating that has, electromagnetism heating, these methods all in various degree obtained certain effect, but the cost height, efficient is low, and is therefore economical inadequately.

The purpose of this utility model provides a kind of economic, practical, infrared, induction oil electric heater that efficient is high.

The utility model is achieved like this.Has sleeve pipe in interior pipe outside, two end faces have identical end socket respectively up and down between sleeve pipe and interior pipe, the left side at the upper surface end socket has sealing plug, seat, on the outer wall of interior pipe, has skeleton, winding screw shape heating wire on skeleton, one end of heating wire is connected with seal socket head lower end, the other end is connected with the outer wall of interior pipe, at casing inner diameter, the middle part of the external diameter of interior pipe has dividing plate, have temperature pick up on the external wall of upper portion of interior pipe, an end of cable is connected with controller, and the other end is connected with sealing plug, ground wire one end is connected with controller, and the other end is connected with interior pipe external wall of upper portion.

The utility model compared with prior art has following advantage:

1, heater is goed deep among the oil reservoir, directly heating in crude oil has reduced intermediate link, saves the energy, has reduced cost; Improve crude output.

2, adopt infrared, induction dual-heated mode; Make full use of electric energy; Avoid magnetic saturation, improve the thermal efficiency; Be substituted with non-ferrous metal with Summoning, save cost.

3, reasonable in design, compact conformation, safe and reliable, be easy to promote the use of.

4, single-phase two-wire power supply utilizes petroleum pipeline (interior pipe 6) as ground wire, saves the electric wire expense, and temperature signal is by feeder line 2 feedbacks.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Accompanying drawing is the utility model overall structure schematic diagram.

To be described in further detail as follows to concrete structure of the present utility model and embodiment below in conjunction with accompanying drawing.

Shown in accompanying drawing, have sleeve pipe 9 in the outside of interior pipe 6, interior pipe 6 promptly is a petroleum pipeline, and oil is heated when flowing through in managing, and sleeve pipe 9 is in order to protect coil, to prevent collision, constituting magnetic loop.Internal diameter at sleeve pipe 9, the external diameter of interior pipe 6 middle part of two end faces up and down has identical end socket 7 respectively, end socket 7 connects support interior pipe and sleeve pipe and constitutes a closed system, prevent that profit from entering, and make coil short, the left side at upper surface end socket 7 has sealing plug, seat 5, on the outer wall of interior pipe 6, has skeleton 10, twine heating wire 8 on the skeleton 10, play heating and produce the magnetic field effect, one end of heating wire 8 is electrically connected with sealing plug seat 5 lower ends, the other end is connected with the outer wall of interior pipe 6, in pipe 6 as a conductor, at sleeve pipe 9 internal diameters, the external diameter middle part of interior pipe 6 has dividing plate 11, square between pipe 6 and sleeve pipe 9 kept necessarily in dividing plate 11 supported, it also is the part of magnetic circuit, on the external wall of upper portion of interior pipe 6, has temperature pick up 4, it is to convert temperature signal to the signal of telecommunication by cable 2, the size of control heating current, one end of cable 2 is connected with controller 1, the other end is connected with sealing plug seat 5 upper ends, ground wire 3 one ends are connected with controller 1, and the other end is connected with interior pipe 6 tops (well head) outer wall.The three-phase 380V alternating current that controller 1 provides outside line is transformed into single-phase alternating current and is transferred to heating wire 8 by two-wire, single line is that pipe 6 and ground wire 3 are connected to the lower end of heating wire 8 in using in this two-wire, another line is single-core cable 2 and sealing plug, seat 5 is connected to heating wire 8 upper ends, heating wire 8 himself generates heat on the other hand in interior pipe 6 sleeve pipes 9 end sockets 7 dividing plates 11 after flowing through AC current on the one hand, produce alternating electromagnetic field, this alternating electromagnetic field is again at interior pipe 6, induce eddy current on sleeve pipe 9 tube walls and make this two tube wall heatings, these two kinds of heat all pass to oil, and oil is heated.The temperature signal of temperature pick up 4 outputs on interior pipe 6 tops also feeds back to controller 1 by single-core cable 2, and this feedback adopts the high frequency modulated mode to realize.
