A kind of paraffin wax cleaning operation pipeline robot

Abstract

The invention discloses a paraffin cleaning operation pipeline robot, which is composed of an energy supply device, a walking device, a cleaning device, a paraffin collecting device, a wax preventing device and a connecting device. Among them, the energy supply device is composed of batteries, which are used for robot walking, cleaning, collecting, and wax-preventing device rotation; The actual working conditions of pipe diameter and different ovality; the paraffin cleaning and collecting device is composed of a spiral cleaning cutter head and a spiral transport rod, which is used for paraffin cleaning and transporting it to the collecting device while using chemical reagents to dissolve and reduce the load; The anti-wax device consists of a nozzle and a microbial culture tank, which is used to spray the mixed bacteria on the inner wall of the pipeline to prolong the wax removal cycle; the ball-and-socket connection device is composed of a ball-head hydraulic rod and a socket-shaped groove. The ball head hydraulic rod is used to extend or compress when cornering, so that the robot can smoothly pass through the curve and rotate flexibly. The robot in the present invention can be widely applied to the problem of wax removal in oil pipelines, improves operation means, increases efficiency, saves operation costs, and finally better guarantees the safety of pipeline transportation.

Description

technical field [0001] The invention belongs to the technical field of pipeline robots, in particular to a pipeline robot for paraffin wax cleaning operation. Background technique [0002] According to statistics, the wax content of 90% of my country's crude oil is between 20% and 40%. With the change of external conditions during transportation, paraffin gradually precipitates in crude oil, crystallizes, and precipitates on the inner wall of the pipeline. Viscosity increases, reducing flow area, increasing flow resistance, further increasing consumption, reducing output, and in severe cases, dangerous accidents will occur if the pipeline is blocked. Traditionally, mechanical, thermal, and chemical reagents are used to remove wax, and coatings, strong magnetism, and cold flow are used to prevent wax. However, the internal environment and operating conditions of the pipeline are complex, the work efficiency is low, and the operating cost is high. Therefore, a Pipeline robots ...

Problems solved by technology

[0002] According to statistics, the wax content of 90% of my country's crude oil is between 20% and 40%. With the change of external conditions during transportation, paraffin gradually precipitates in crude oil, crystallizes, and precipitates on the inner wall of the pipeline. Viscosity increases, reducing flow area, increasing flow resistance, further increasing consumption, reducing output, and in severe cases, dangerous accidents will occur if the pipeline is blocked

Traditionally, mechanical, thermal, and chemical reagents are used to remove wax, and coatings, strong magnetism, and cold flow are used to prevent wax. However, the internal environment and operating conditions of the pipeline are complex, the work efficiency is low, and the operating cost is high. Therefore, a Pipeline robots have important scientific significance and obvious socioeconomic benefits

[0003] The traditional pipe wax removal robot has low adaptive pipe diameter change ability, insufficient driving force, easy to cause jamming, and poor curve passability; the paraffin is cleaned by mechanical scraping during the walking process, and the paraffin accumulated after the operation is not collected. ; The wax removal cycle of the pipeline is short, usually between 1 and 3 months, and the cost of each wax removal is relatively high

And there are unsafe factors in the smooth and reliable operation of pipeline robots

[0004] In view of the immature application of domestic pipeline robots, under the actual industrial demand, different from the traditional design and development, aiming at the easy jamming phenomenon in the process of cleaning paraffin at the thick layer of wax deposits, an efficient and environmentally friendly, low cleaning cost is invented. , a pipeline robot with variable diameter, flexible bending, and can collect the paraffin accumulated after operation to avoid jamming, and prolong the wax removal cycle through the anti-wax technology
