Magnetizing device capable of reducing petroleum viscosity in oil pipeline

Abstract

The invention relates to a magnetizing device capable of reducing the petroleum viscosity in an oil pipeline, comprising a stainless steel pipe, a pipe-shaped magnetic yoke, non-magnetic tile-shaped blocks, an upper tile-shaped permanent magnet set and a lower tile-shaped permanent magnet set. The stainless steel pipe is arranged in the pipe-shaped magnetic yoke along the axis of the pipe-shaped magnetic yoke; both ends of the stainless steel pipe extend out of the pipe-shaped magnetic yoke; the upper tile-shaped permanent magnet set and the lower tile-shaped permanent magnet are spaced from each other by two non-magnetic tile-shaped blocks and are symmetrically arranged between the stainless steel pipe and the pipe-shaped magnetic yoke by taking the axis of the pipe-shaped magnetic yoke as a center; the tile-shaped permanent magnet set consists of at least two pairs of permanent magnets which have different thicknesses and are connected with each other by tile-shaped middle magnetizer heteroples; and the magnetization directions of the permanent magnets are consistent with the axial direction of the stainless steel pipe. The invention has the advantages that the device has simple structure, requires no outside resources and is convenient to use and install; the gradient magnetic field distribution reduces the magnetic field strength at the tail end of a magnetic ring device, relieves damage of petroleum flowing orderly as a result of strong magnetic field strength and reduces the viscosity of crude oil.

Description

technical field [0001] The invention belongs to the field of magnetization technology, and in particular relates to a magnetization device capable of magnetizing oil in an oil pipeline, thereby reducing oil viscosity, increasing oil flow rate, and improving oil transport efficiency. Background technique [0002] Petroleum from different oil fields contains a certain proportion of paraffin wax, and the temperature at which paraffin wax precipitates from petroleum (hereinafter referred to as the crystallization point) is 32-38°C. In particular, paraffinic crude oil is characterized by high wax content, high viscosity, and high freezing point. After the oil is extracted from the ground and enters the oil pipeline, the temperature gradually decreases, and when it reaches the crystallization point, paraffin wax begins to precipitate. The precipitated wax crystals condense together with the decrease of temperature to form wax crystal clusters, which increases the viscosity of oil...

AI Technical Summary

Problems solved by technology

The advantage of the electromagnetic magnetization device is that the magnetic field will not decrease with the passage of time, and the strength of the magnetic field can be controlled. The disadvantage is that the excitation coil needs an external power supply, and the cost is relatively high compared with the permanent magnet magnetization device. It is greatly affected by the site environment and volume factors

The advantages of the permanent magnet magnetization device are simple structure, cheap price, no need for external energy supply, and basically no maintenance after installation. The disadvantage is that the magnetic field strength is fixed and cannot be adjusted, and the magnetic field strength will gradually weaken over time and affect the processing effect.
