Detailed description of the invention
Embodiment 1
As shown in Figure 1, the ultrasonic wax control device of a kind of permanent magnetism, at least comprises: supersonic generator 1, cable 2, ultrasonic transducer 3, permanent magnet 4, magnet cover 5, protection box 6, interior pipe and flange; Described interior pipe two ends are equipped with a flange, and inner tube wall is provided with ultrasonic transducer, and ultrasonic transducer is electrically connected by the supersonic generator of cable with outer wall of inner tube upper end; Outer wall of inner tube is provided with permanent magnet, and permanent magnet is positioned at the lower end of supersonic generator, and permanent magnet outer setting has magnet cover; Interior pipe outer cover between two flange has protection box, and ultrasonic transducer, permanent magnet and magnet cover is all in protection box; N pole and the S pole of described permanent magnet 4 are alternately arranged by combination, make it form screw alternating high-intensity magnetic field.
The utility model operationally, interior pipe 7 two ends are respectively through flange 8 connected pipes, when energized, supersonic generator 1 converts electric energy to the high-frequency ac signal of telecommunication matched, ultrasonic transducer 3 is passed to by cable 2, convert dither to through ultrasonic transducer 3, process ducted crude oil.Ultrasonic wave produces cavitation effect, mechanical effect, fuel factor, Emulsification effect weaken the mutually coalescent cohesive force of molecule, the molecular separating force of wax crystallization and surface tension; Under strong magnetic field action, the charged particle in oil is subject to the effect of Lorentz force, produces magnetization, the gathering of paraffin molecule and the precipitation of wax crystalline substance in effective crude oil for inhibiting.Meanwhile, to the rational deployment of permanent magnet and the optimal design of structure, make it form screw alternating high-intensity magnetic field, the field intensity in magnetic field is high, magnetic journey is long, there is again parallel place inner existing vertical place, strengthens the wax control result in magnetic field.After magnetic field and ultrasonic coupling superpose, under magnetic fields, paraffin molecule aligns and does olderly flowage, and under ul-trasonic irradiation, long-chain wax molecular structure is interrupted, its internal friction diminishes, the mobility of waxy crude oil improves, and magnetic field and ultrasonic wave synergistic reaction, wax control result is better.
Embodiment 2
On the basis of embodiment 1, described ultrasonic transducer 3 is tubular, is enclosed within interior pipe 7.Described permanent magnet 4 is the arc bodies arranged alternatively up and down by combination by multiple N pole and S pole.Permanent magnet 4 is two, makes that its magnetic field forming screw alternating high-intensity magnetic field is stronger, magnetic journey is long.The region of magnetic field and ultrasonic coupling superposition is larger, and, there is again parallel place inner existing vertical place, strengthens the wax control result in magnetic field.
