Non-contact type pipe wall wax deposition removing device and pipe wall wax deposition removing system

Abstract

The invention relates to the technical field of crude oil pipeline removing, in particular to a non-contact type pipe wall wax deposition removing device and a pipe wall wax deposition removing system. The non-contact type pipe wall wax deposition removing device comprises a magnetic impeller, a center rotating shaft and at least two sets of clamping pulley assemblies. Each clamping pulley assembly comprises a pulley rack and a plurality of clamping pulleys which are fixed on the edge of the pulley rack. The clamping pulleys and a pipe wall are attached, when the removing device operates, the inner wall of an oil pipe can not be damaged, crude oil in the pipe penetrates through the pulley racks and then impacts the magnetic impeller, the magnetic impeller rotates along with the center rotating shaft under the effect of fluid pressure, accordingly, an alternating magnetic field is formed in the pipe, and induced eddy currents are formed on the pipe wall. The pipe wall achieves self heating, deposited wax is made to be peeled and cracked, and the wax removing effect is good. The non-contact type pipe wall wax deposition removing device and the pipe wall wax deposition removing system are simple in structure, do not need an external power source in the magnetoelectricity conversion process, and have the advantage of being low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of crude oil pipeline cleaning, in particular to a non-contact pipe wall wax removal device and a pipe wall wax removal system. Background technique [0002] At present, most of the crude oil produced in my country is "three-high crude oil" with high wax content, high freezing point, and high viscosity. Waxy crude oil is often heated for pipeline transportation. Since the ambient temperature of the pipeline is lower than the wax precipitation point of the oil, the wax in the crude oil precipitates and deposits on the pipe wall. [0003] After the crude oil pipeline is used for a period of time, the thickness of the wax layer on the pipe wall will reach a certain thickness, thereby reducing the inner diameter of the pipeline, resulting in a reduction in pipeline delivery capacity or an increase in energy consumption of centrifugal pumps. In addition, the transportation volume of hot waxy crude oil pipeline i...
