Abstract

The invention relates to electric heating equipment for heating crude oil and a temperature control method of the electric heating equipment. An oil conveying coil pipe and electric heating pipes arearranged in an inner cavity of a furnace body, heat conduction media fill the inner cavity, a medium temperature sensor of a control system and the electric heating pipes are connected with a PLC, wherein the medium temperature sensor is used for collecting the temperature of the heat conduction media, the PLC is used for receiving the data from the medium temperature sensor and controlling the plurality of electric heating pipes through return difference delay according to the data and the preset heat conduction medium temperature, and the return difference delay is the duration generated when the heat conduction medium temperature difference value meets the preset return difference temperature. In the using process of the electric heating equipment, no open fire is generated, and thus potential safety hazards such as fire disasters and explosion are eliminated; the electric heating equipment is driven by electric energy, tail gas is not generated during use, so that pollution to theenvironment is avoided; meanwhile, heat loss caused by tail gas emission is avoided, and thus the heat conversion efficiency is improved; and the electric energy replaces fuel gas, so that the electric heating equipment has a wider application range.

Description

technical field [0001] The invention relates to the technical field of electric heating equipment, in particular to an electric heating equipment for heating crude oil and a temperature control method thereof. Background technique [0002] In the process of crude oil transportation in the oil field, due to the low temperature in some oil wells, the temperature of the produced crude oil is low and the viscosity is high, which is not easy to flow in the oil pipeline. In order to improve the fluidity of crude oil in the oil pipeline, it is necessary After production, the temperature of crude oil is increased, thereby reducing the viscosity of crude oil and increasing its fluidity. At present, oil fields use gas-fired water jacket furnaces as crude oil heating equipment to improve the temperature and fluidity of crude oil. [0003] The gas-fired water jacket furnace is a crude oil heating equipment often used in oil fields. It burns and generates heat through the natural gas in...
