Abstract

The invention provides a high-frequency electromagnetic induction heating device. The high-frequency electromagnetic induction heating device comprises a heating cabinet. A programmable logic controller (PLC), a high-frequency induction heating power source, a high-frequency electromagnetic induction heating body, a display unit and a sensor set are arranged inside the heating cabinet, the PLC, the high-frequency induction heating power source and the high-frequency electromagnetic induction heating body are sequentially electrically connected, and the display unit and the sensor set are electrically connected with the PLC. The high-frequency electromagnetic induction heating body is connected with a crude oil storage tank to be heated through a pipeline; the PLC controls the high-frequency electromagnetic induction heating body to be powered on or off through the high-frequency induction heating power source. The novel high-frequency electromagnetic induction heating device suitable for the special industry of the oil field is developed in an integrated mode and meets the heat requirements of the places such as oil field crude oil production and integrated conveying and personnel living places. The heating power and the best size of the structure of the induction heating body are configured according to the specific heat requirement, the highest efficiency of electro-heat conversion utilization is realized, no noise or open fire is generated during operation, fossil fuel is not used, pollution is avoided, no requirement for the water quality exists, and scaling is avoided. Descaling at regular times is not needed, emission is avoided, automatic control is convenient, and digital management is adopted.

Description

technical field [0001] The invention belongs to the technical field of oilfield crude oil production, and in particular relates to a high-frequency electromagnetic induction heating device. Background technique [0002] The underground crude oil extracted from most of the oilfields in western my country contains a large amount of paraffin, especially the Changqing Oilfield and the main The Yanchang Oilfield, which is distributed in northern Shaanxi, is located in the Ordos Basin, with deserts, grasslands and hills in the north, and the Loess Plateau in the south. The terrain is complex and difficult to manage. [0003] At present, most of the methods of oil production and oil collection in oil fields are transported from oil wells to oil gathering stations or centralized processing stations by pipelines for subsequent processing. Due to the large temperature difference between the ground and the underground, after the crude oil is pumped out of the ground, a large amount of ...
