Compound electromagnetic induction heater of oil storage tank

Abstract

The invention relates to a compound electromagnetic induction heater of an oil storage tank, in particular to a heater for overcoming the defects of a traditional electrical heated tube. The compound electromagnetic induction heater is especially suitable for rapidly heating crude oil in the oil storage tank of an oil field, is beneficial to oil and water separation, and consists of a power supply, an overtemperature protection temperature controller, an oil temperature display temperature controller, a high-frequency controller, an anti-explosion metal hoses, an oil storage tank, a hoisting hook, a sealing device, an oil temperature sensor, an overtemperature protection sensor, a nichrome heating ring, a high-frequency electromagnetic induction heating ring, a heater box, a heater box machine angle, a high-frequency heating core tube, a nichrome heating core tube and a controller box, wherein wires in the heater box are connected with the temperature controller and the high-frequency controller in the control box through the anti-explosion metal hoses. The compound electromagnetic induction heater has the beneficial effects that enough heat exchange area is ensured, and the heat efficiency is improved; when the core tubes are heated, the crude oil ascends rapidly to perform convective circulation movement, which is beneficial to the oil and water separation, so that the temperature at each part of the oil storage tank is more uniform; and an independent overtemperature protection function is realized, so that safe accidents do not occur.

Description

technical field [0001] The invention relates to a composite electromagnetic induction heater for an oil storage tank, in particular to a heater which solves the shortcomings of traditional electric heating tubes. It is especially suitable for rapid heating of crude oil in oil storage tanks in oil fields, which is beneficial to the separation of oil and water. Background technique [0002] At present, there are many kinds of electric heaters for crude oil storage tanks, basically all of which use traditional resistance heating tubes as heat sources. The traditional resistance heating tube has the following disadvantages: the small heat transfer area leads to low thermal efficiency; the small heat transfer area leads to local high-temperature fouling, and even burns crude oil, which is poor in safety; its structure is not conducive to liquid circulation, has no stirring effect, and is not It is beneficial to the separation of oil and water; when heating, some places in the sa...
