Abstract

The invention belongs to the field of surface cleaning, and particularly relates to a particle jet impingement pipeline cleaning device, including a high-pressure cylinder, a primary mixing chamber, a secondary mixing chamber, an outer washing track, a rotating moving device, a circulating slurry pump, a magnetic separator, and a high-pressure pump etc., can realize the surface cleaning of scales with different hardness on the inner and outer walls of the pipeline. After the steel particle jet impacts the scales on the pipeline wall at high speed, a huge instantaneous impact stress will be generated on the impact surface, which can quickly break the scales and realize It ensures the efficient removal of pipeline scale, and the spherical steel particles have little erosion and wear on the pipeline wall, which can better protect the wall of the pipeline body. At the same time, the steel particles have high strength and high hardness, and can be recovered by magnetic separation. , realize the recycling of particles, and the jet fluid can also be recycled. This device can effectively improve the efficiency and quality of pipeline cleaning, reduce cleaning costs, and increase the safety and stability of pipeline operation.

Description

technical field [0001] The invention relates to a particle jet impingement pipe cleaning device, which belongs to the field of surface cleaning. Background technique [0002] Pipelines play an important role in oil extraction, transportation and processing. The transport medium of oil and gas pipelines is oil and gas, which contains various components such as paraffin, oxides, sulfides, and sand particles. With the long-term use of the pipeline, such components will cause scaling on the inner and outer walls of the pipeline and cause corrosion to the pipeline. In severe cases, the pipeline may be blocked, broken, etc., thereby causing production accidents. In order to avoid such accidents, it is necessary to periodically clean and inspect the pipeline to ensure the stability and safety of the pipeline operation. [0003] At present, the commonly used pipeline cleaning methods include chemical cleaning, mechanical scraper cleaning, high-pressure water jet cleaning, abrasive...

AI Technical Summary

Problems solved by technology

Among them (1) Chemical cleaning requires chemical agents, which will cause corrosion damage to the pipeline itself, and the use of chemical agents will cause environmental pollution. After the leakage of dangerous chemicals, serious safety production accidents may occur, endangering the safety of life and property

(2) Mechanical scraper cleaning uses a mechanical method to scrape and clean the inner and outer surfaces of the pipeline. The cleaning effect is not ideal for scales with high hardness and viscosity. , will also have an impact on the surface of the pipe body

(3) High-pressure water jet cleaning is an efficient and clean cleaning method, but it is not effective for cleaning scales with high hardness, oil stains, rust stains, etc. Pure high-pressure water jet has limited impact ability, and it is difficult to achieve hard scaling. Efficient cleaning

(4) Abrasive jet cleaning technology uses abrasives such as quartz sand. By adding abrasives to the jet, the abrasive jet impacts the scale at high speed, which can realize the cleaning of hard scale. However, the recovery of abrasives such as quartz sand is difficult and costly. Abrasive jets can easily damage pipe walls if not well controlled

(5) The cost of ultrasonic cleaning equipment is expensive, and the requirements for the cavitation effect generated are relatively high, and the cleaning distance is limited
