1-3 in conjunction with the accompanying drawings, the utility model will be further described:
The utility model mainly is made up of master controller and the coil that is wrapped on the gathering line, and coil is fixed to above the pipeline by clamp, and coil adopts high temperature resistant approved cable; Described master controller mainly is made up of main control box 2, digital integrated electronic circuit frequency modulation frequency variator 3, electromagnetism heating controller 4, display screen 5, described digital integrated electronic circuit frequency modulation frequency variator 3, electromagnetism heating controller 4 are fixed on main control box 2 inner chambers, the outside is provided with display screen 5, and control all is connected the position that is shown to liquid crystal display panel 5 to its working state with switch, presses the mode shown in the figure; Described electromagnetic signal reset coil 6 is wrapped on the pipeline by identical direction respectively with electromagnetic induction heating coil 7, the two ends of described electromagnetic signal reset coil 6 are connected with the input/output port of digital integrated electronic circuit frequency modulation frequency variator 3 respectively, and the two ends of electromagnetic induction heating coil 7 are connected with the input/output terminal of electromagnetism heating controller 4 respectively.Main control box 2 is fixed on the support 8 by screw, then frame bottom is imbedded underground fixing.The power interface of main control box 2 is connected with power supply 1 (220V/380V) by cable 9, and the main control box 2 outer explosion-resistant enclosures that are provided with are provided with explosion-proof pillar outside the cable 9.
Working principle of the present utility model is:
When device work, the electromagnetic induction heating coil that is wrapped on pipeline produces the alternation magnetic line of force, the irony pipeline surface promptly cuts the alternation magnetic line of force and produce the electric current (being eddy current) of alternation in metal pipe line, eddy current makes the random motion of iron molecule high speed, and molecule runs foul of each other, rubs and produces heat energy.Thereby the mode with pipeline self heat production plays the purpose that adds the oil product of pining for.Because be irony pipeline self-heating, so heat conversion is high especially, can reach 95%, this is a significant advantage of electromagnetism heating.After oil product was heated, the solid-state or semisolid composition in the oil product reduced even disappears, the oil product reduced viscosity, and mobile increasing, thus reduce wax deposition, improve transfer rate.
When device work, be wrapped in the electromagnetic signal reset coil on pipeline, owing to be the DC frequency-changing signal, can handle the oil product in the oil pipe being carried out variable-frequency electromagnetic, after oil product is handled through magnetization resonance, make the diamagnetic substance that does not have magnetic moment originally--paraffin, under the action of a magnetic field, its molecule forms electronics circulation (change has taken place the orbiting state that is electronics), has produced induction field in circulation, it is induced magnetic moment, disturb and destroyed the orientation of the utmost point of moment in the paraffin molecule, the wax molecule is aligned under the action of a magnetic field, do to flow in order, overcome the active force between the paraffin molecule, made it not form paraffin crystal by the requirement of crystallization.By behind the magnetic field, the adhesive force when having weakened the paraffin molecule crystallization suppresses the generation of paraffin nucleus, stoped the growth and the gathering of paraffin crystal, and the wax particle of separating out is tiny and loose for the particulate that forms the wax crystalline substance.Simultaneously, the frequency conversion strong magnetic field action has changed the forming process of the nucleus of wax composition, makes crystal be condensed into big and loose granule, is easy to be taken away by liquid stream the deposition of minimizing wax.
Because the attribute of wax composition is different with the condition that forms crystallization under the different condition, its inner free frequency is just different, so its resonant frequency also is not the same.Therefore, adopt the frequency conversion resonance technique, just can guarantee to make the wax composition molecule under any oily condition to produce resonance, thereby reach the purpose of wax control.Frequency conversion is means, and resonance is purpose, and the process of frequency conversion is sought the process of the free frequency in the wax composition exactly, and the frequency of variation has covered the free frequency of all wax compositions, has just effectively guaranteed can both play any wax composition the effect of wax control.
Through this double processing, can play the effect of effective wax-proof viscosity reducing drag reduction to the oil product of carrying in the middle of the gathering line.When if pipeline is longer, install one every one kilometer and overlap this device, just can solve the smooth problem of all pipeline blocking barriers that causes because of wax deposition fully.Thereby keep pipeline efficiency of transmission efficiently, and then reach the purpose that improves production capacity.
