Description

Technical Field

[0001] The utility model belongs to the technical field of liquid heating equipment, and in particular relates to an oil heating unit. Background Art

[0002] Since the temperature of oil out of the ground is low, the oil itself becomes more viscous and has poor fluidity. Existing oil transportation systems generally have heating devices in the oil transportation systems to improve the fluidity of the oil, thereby avoiding the oil flow rate in the oil pipeline being too slow.

[0003] At present, there are two common oil heating devices: oil tank heating and oil pipeline heating. Among them, the oil tank heating method is: firstly, an auxiliary heating pipe is wrapped around the outer periphery of the oil tank, and then the oil in the oil tank is directly heated by the heating medium flowing in the heating structure. However, due to the large volume and capacity of existing oil tanks, this oil heating method has the problems of high investment cost and slow heating speed.

[0004] The heating method of the oil pipeline is: first inject a heat transfer medium into the heating chamber in the heating furnace, and connect the oil pipeline with the auxiliary heating pipeline immersed in the heat transfer medium, then burn fuel gas, coal gas and other combustion materials to heat the heat transfer medium in the heating chamber, and indirectly heat the oil in the auxiliary heating pipeline through the heat transfer medium heated to a certain temperature, so as to achieve the ultimate heating purpose. However, since the existing oil pipeline heating device generally sets the combustion structure for heating the heat transfer medium and the auxiliary heating pipeline for transporting oil in the same device, it not only has a complex overall structure, but also has a high risk factor, and even in serious cases, it will directly explode, causing safety accidents.

[0011] Furthermore, the heating box is provided with an exhaust port, and exhaust operation can be performed through the exhaust port.

[0012] Furthermore, the heating box is provided with a temperature sensor, and the temperature of the heat transfer medium in the heating box is monitored in real time through the temperature sensor.

[0013] Furthermore, temperature sensors are provided at both the input and output ends of the auxiliary heating tube, and the temperature sensors therein monitor in real time the temperature of the heat transfer medium in the auxiliary heating tube when it enters the heating box and the temperature when it is output outside the heating box.
