Pressure-type high-power double-sided electromagnetic heater

Abstract

The invention provides a pressure-type large-power bilateral electromagnetic heater and belongs to the technical field of electric heating. The pressure-type large-power bilateral electromagnetic heater comprises heating water tanks, an electromagnetic coil, a drawer-type assembly, a magnetizing coil, a frequency variable ultrasonic energy converter and the like. Each heating water tank is a flatcylinder, and liquid can be heated or steam is produced under pressure. The electromagnetic coil is arranged between the two adjacent heating water tanks, bilateral heat generation is achieved while water electric separation is conducted, the electromagnetic heat generation area and the electromagnetic coil utilization rate are effectively increased, and electromagnetic radiation is reduced. Through the combined structure of the heating water tanks and the drawer-type assembly, production and mounting are quite facilitated, and hotline overhaul and maintenance can be achieved. Through scale prevention of the magnetizing coil and the scale removing effect of the frequency variable ultrasonic energy converter, the service life of the system is effectively prolonged, the efficiency of the system is effectively improved, additionally the drawer-type bilateral electromagnetic heat-generating system further has the advantages that the production cost is low, the technique is simple, capacityincreasing is convenient, the size is small, the operation cost is low, the energy saving effect is remarkable, and safety and reliability are achieved, and can be widely applied to various electricheating occasions, and the energy saving and environment protection effects are effectively improved.

Description

technical field [0001] The invention relates to an electromagnetic heating system, in particular to a high-power electromagnetic heating system capable of withstanding pressure and heating on both sides. It belongs to the technical field of electric heating. Background technique [0002] The principle of electromagnetic intermediate frequency heating is very mature at present, and two main methods are generally used in application. One is to wind the electromagnetic coil on the heated body, and the other is to place the heated body on the side of the disc electromagnetic coil. Their common feature is that compared with the heating coil, they all generate heat on one side, and the heating area is less than 50%. The other side needs to be equipped with a magnetic conductive material and a heat insulating layer, which has a certain amount of heat loss and will cause more electromagnetic radiation. radiation. Each power model is independently designed and manufactured, the pro...
