Description
Affiliated technical field
The utility model relates to a kind of electromagnetic induction heater, especially a kind of energy savings, the electromagnetic induction heating coil apparatus that is used for the pipeline heating reasonable in design, this device can be applicable in the heating to crude oil pipeline, also can be used for simultaneously fields such as plastic products, the pipeline heating technique of rubber.
Background technology
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the patent No. is that 200610031824.0 file discloses a kind of composite laminate electromagnetic induction heating coil 2, this composite laminate electromagnetic induction heating coil 2 is installed in the outside of metallic conduit 1 and is connected with electromagnetic controller 5 by lead 13, and electromagnetic controller 5 is connected with external power supply by power line 4 again.Composite laminate electromagnetic induction heating coil 2 no magnetic cores, between the outer surface of its inner surface and metallic conduit 1, be provided with insulation material layer 3, it is characterized in that: outside the metallic conduit 1 of need heating load, be equipped with by the superposeed composite laminate electromagnetic induction heating coil 2 of the compound semicircle shape plane coiling that forms of double-deck solenoid, wherein, composite laminate electromagnetic induction heating coil 2 is the superimposed formations of double-layer coil, and the magnetic line of force superposition after the double-deck electromagnetism heating collar stack is on the metallic conduit 1 of need heating load.And this composite laminate electromagnetic induction heating coil 2 is that process is with plane coiling spiral coil, and then multilayer build-up gets up, and be rolled into the semicircle shape coil according to the profile of metallic conduit 1, described composite laminate electromagnetic induction heating coil 2 places between the overcoat 6 and interior cover 7 that insulating materials makes, and be provided with connector 8, the two semicircle composite laminate electromagnetic induction heating coils 2 that are used to be connected two semicircle composite laminate electromagnetic induction heating coils 2 in the joint portion of overcoat 6 and interior cover 7 and form a full circle that matches with carried metal pipeline 1 by connector 8.Electromagnetic wire between the double-deck electromagnetism heating collar connects by polyphone, adopt a lead coiling to form, the entrance and exit of every layer line circle just in time joins, the mode of connection that coil adopts end of the same name to link to each other, and promptly the line tail of first coil 9 is the end of a thread of second coil 10.After electric current was input to electromagnetic controller 5 by power line 4,5 of electromagnetic controllers produced the superaudio electric current and receive on the composite laminate electromagnetic induction heating coil 2, form strong alternating magnetic field.The metallic conduit of this magnetic field and composite laminate electromagnetic induction heating coil 2 inside forms magnetic loop, this electric current is converted into heat energy by the self-resistance effect of metallic conduit again, thereby metallic conduit 1 is heated intensification, and acts on the medium (as plastics, crude oil, water) that needs in the metallic conduit 1 to heat.
The inventor finds, in above-mentioned technology, same electromagnetic heating coil is to be uniformly distributed in pipeline outer wall along water back substantially in the mode of two-layer or multilayer, rounding type, circular arc type, and this distribution mode has the following disadvantages.
First, heat utilization efficiency is low: add at the pipeline of oil well and pine for, owing to what extract out from producing well is by crude oil, water, three kinds of materials of gas are formed, bottom in this just feasible oil pipeline of laterally installing, the middle part is water and crude oil often, and top often is gas, because water, crude oil, the specific heat difference of gas, required heat also is different, simultaneously in conjunction with the hot principle that rises, the bottom of general conveyance conduit, middle part institute calorific requirement is many, need heating power also big, and the required heating power in top is less, and traditional same electromagnetic heating coil is evenly distributed on the pipe circumference, the power of heating also is equally distributed, thus often cause the conduit upper heating power that surplus is arranged, and water and oil ratio example is at most and to need most the heating power of pipeline bottom of heating not enough, make heat energy dissipation that conduit upper is not utilized in the middle of air, this comprehensive utilization for heat energy is influential.Also be unfavorable for simultaneously the raising of the thermal efficiency.
The second, heating is inhomogeneous: in the production of plastic cement industry, need the barrel of horizontal installation be heated, because traditional same solenoid is evenly distributed on the barrel, make that the first half heating power of charging basket is identical with the Lower Half heating power, because the principle that heat rises makes barrel the first half temperature of laterally installing be higher than the latter half, this barrel for the even heating of two parts needs up and down be disadvantageous, to the quality of production also is influential, and the raising to the utilization rate of heat energy is disadvantageous equally simultaneously.
