管道式电磁感应加热器利用直线电机的概念,按照一定的规律布设三相行波磁场感应线圈,使其产生行波磁场,进而在管道上感应涡流,加热管道;电源采用三相对称方波中频,能够实现涡流、磁滞和谐波加热,效率高。管道感应加热属于无热源加热技术,无明火,适合于高危防爆场所的设备加热,同时行波磁场加热方式可大大降低原油分子的结合力,使稠油在较低温度下输送而不会凝结,免除传统加热炉的缺点,安全可靠。
Pipeline electromagnetic induction heater using the concept of linear motor, according to a certain regular pattern of three-phase magnetic field induction coil, so that it generates traveling magnetic field, and then induced eddy currents in the pipe, heating pipes; power supply using three-phase symmetrical square wave intermediate frequency , Can achieve eddy current, hysteresis and harmonic heating, high efficiency. Pipeline induction heating is a non-heat source heating technology, no open flame, suitable for high-risk explosion-proof equipment, heating, while traveling wave magnetic field heating can greatly reduce the cohesion of crude oil molecules, so that heavy oil at lower temperatures without condensation, Relieve the shortcomings of traditional heating furnace, safe and reliable.
