Abstract
Provided is a novel electromagnetic heating apparatus for oil gas pipeline heat tracing. The electromagnetic heating apparatus is mainly used in oil gas pipeline heat tracing and comprises an insulating thermal insulation layer, an inductive coil, a temperature control device, a sb variable-frequency power supply, a housing, and an oil gas pipeline. The insulating thermal insulation layer is wrapped around the oil gas pipeline. The inductive coil is wound around the insulating thermal insulation layer and then is connected with the sb variable-frequency power supply. The temperature control device is installed on the oil gas pipeline and then is connected with the sb variable-frequency power supply. Electricity with power frequency is converted into electricity with high frequency from 20 to 40 kHz by the sb variable-frequency power supply to be outputted to the inductive coil and then the electricity with high frequency from 20 to 40 forms eddy current on the inner wall of the oil gas pipeline so as to achieve heating. The electromagnetic heating apparatus has characteristics of reasonable structure, controllable temperature and no external environmental influence, high heating efficiency, an obvious energy-saving effect, and secure and reliable operation.
Description
Technical field
The utility model relates to a kind of New Heating of oil and gas pipes companion heat.
Background technology
At the main companion's hot mode that adopts resistance, steam, conduction oil of existing oil and gas pipes companion heat, there is following problem in this companion's hot mode: 1, be subject to ambient temperature effect and cause accompanying hot temperature low, do not reach temperature requirement.2, waste energy.3, useful life short, maintenance cost strengthens.4, security and stability is poor.
Summary of the invention
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art part, provides a kind of a kind of companion's hot charging that allows oil and gas pipes directly generate heat to put.The utility model is mainly by insulation heat preservation layer (1), induction coil (2), and temperature control equipment (3), sb variable frequency power supply (4), shell (5), oil and gas pipes (6) forms.The utility model can be realized by following frame mode: a kind ofly for oil and gas pipes, accompany hot Novel electromagnetic heater, comprise insulation heat preservation layer (1) is wrapped in after oil and gas pipes (6) is wrapped on insulation heat preservation layer by induction coil (2) after upper and connects sb variable frequency power supply (4), temperature control equipment (3) is arranged on oil and gas pipes (6) and is connected with sb variable frequency power supply (4) after upper.Shell (5) is used for protecting induction coil not to be subject to extraneous destruction.Principle of the present utility model is thereby that the electric high-frequency electrical by sb variable frequency power supply output 20-40kHz of power frequency is realized heating at inner-walls of duct formation eddy current after induction coil.Insulation heat preservation layer plays heat insulation a, insulating effect, thereby the temperature control control device reaches the temperature control purpose according to the output of temperature required control sb frequency converter in pipeline.
The utility model changes original resistance, steam, conduction oil companion heat by the hot mode of transmitting, and a kind of directly a kind of New Heating of heating of pipeline that makes is provided.Take 100 degrees centigrade to 200 degrees centigrade be optimal way, and temperature rise speed is fast, outside does not produce heat, compared with prior art, the utility model produces because of following characteristics the beneficial effect made new advances.The one firing rate is fast, is not subject to external environment influence.Its two, the heat efficiency is high, more energy-conservation more than 50% than original companion's hot mode, its three, long service life.Induction coil itself does not produce heat, and the later stage is substantially without maintenance cost.Its four: security performance is high, and temperature control is accurate.
