Vacuum type liquid heating conveying pipeline

Abstract

The invention discloses a vacuum type liquid heating conveying pipeline. The vacuum type liquid heating conveying pipeline comprises a flange plate and an oil conveying pipeline. The oil conveying pipeline is in fixed sealing connection with the flange plate. The oil conveying pipeline is provided with an outer pipeline layer and an inner pipeline layer. A vacuum cavity is formed between the outerpipeline layer and the inner pipeline layer. The outer pipeline layer and the inner pipeline layer are provided with a channel for installing a heating pipe. The channel is in sealed connection withthe outer pipeline layer and the inner pipeline layer. The heating pipe is arranged in a pipeline body of the inner pipeline layer. A gear pump is arranged between a water inlet and a water outlet ofthe heating pipe. The outer pipeline layer is provided with a water tank. The water tank is internally provided with an electric heating pipe. The water inlet and the water outlet of the heating pipeare connected with the water tank. The vacuum type liquid heating conveying pipeline is provided with the heating pipe, the heating pipe can heat petroleum when the petroleum is conveyed for a long distance, the viscosity of the heated petroleum is reduced, the heating pipe in a heating cavity heats the petroleum through hot water, and compared with electric heating for directly heating the petroleum, water heating is safer.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery, in particular to a vacuum type liquid heating transportation pipeline. Background technique [0002] Petroleum is a fluid mineral deeply buried in the ground. During the process of oil extraction, oil and gas flow from the reservoir to the bottom of the well, and then rise from the bottom of the well to the wellhead. The role of petroleum in the national economy Petroleum is an important energy source. Compared with coal, it has the advantages of high energy density, convenient transportation and storage, and less pollution to the atmosphere after combustion. In the composition of the world's energy consumption, oil has surpassed coal and ranked first. [0003] In the process of oil extraction, pipeline transportation is required. Oil is transported through pipelines. When the temperature is low, the viscosity of oil is high, which brings difficulties to transportation. It is necessa...

AI Technical Summary

Problems solved by technology

After the pipeline is scaled, the pipeline will shrink and the flow area will become smaller, resulting in pressure loss, reduced displacement and pipeline blockage. At the same time, in a low temperature environment, the viscosity of oil will increase, and the fluidity will deteriorate, which will easily cause blockage

Most of the existing oil extraction equipment can achieve the antifreeze effect, but the antifreeze measures adopted are complicated and the antifreeze effect is poor

In order to solve these problems, an oil production pipeline that can prevent freezing and blockage is designed to solve the problems of excessive oil viscosity and poor flow
