Anti-corrosion device for pipeline on-line film forming of oil refining and chemical engineering device

Abstract

The invention belongs to the technical field of pipeline corrosion prevention, and particularly relates to a corrosion prevention device for pipeline online film forming of an oil refining and chemical engineering device, the corrosion prevention device comprises a base, a plurality of pipeline grooves are formed in the base, a plurality of clamping heating mechanisms are arranged on the inner walls of the two sides of each pipeline groove, and two sliding rails are fixedly arranged on the base; the two sliding rails are jointly connected with a supporting frame in a sliding mode, and a movable adjusting mechanism matched with the supporting frame is arranged on the base. According to the pipeline anti-corrosion device, anti-corrosion treatment can be conducted on multiple pipelines at the same time, the anti-corrosion operation efficiency is effectively improved, film forming liquid can be well diffused on the inner walls of the peripheries of the pipelines, the film forming effect is guaranteed, meanwhile, excessive film forming liquid generated in the operation process can be recycled, waste is avoided, and in addition, the anti-corrosion effect is improved. According to the device, the pipeline placement stability can be guaranteed, and the pipeline can be rapidly heated.

Description

technical field [0001] The invention belongs to the technical field of pipeline anticorrosion, and in particular relates to an anticorrosion device for online film formation of pipelines of oil refining and chemical equipment. Background technique [0002] The anti-corrosion technology of pipelines in oil refining and chemical plants is one of the urgent problems in the petroleum industry. At present, the main anti-corrosion method is to coat the inner walls of equipment and oil pipelines with anti-corrosion materials to form anti-corrosion coatings. [0003] Nowadays, when carrying out anti-corrosion treatment on oil pipelines, the film-forming liquid is usually injected into the pipeline through an online film-forming anti-corrosion device, and then the pipeline is heated, so that the film-forming liquid can be heated to form a coke film attached to the inner wall of the pipeline. Then the anti-corrosion layer of the pipeline is formed. However, in the process of using the...

Problems solved by technology

[0003] Nowadays, when carrying out anti-corrosion treatment on petroleum pipelines, the film-forming liquid is usually injected into the pipeline through an online film-forming anti-corrosion device, and then the pipeline is heated, so that the film-forming liquid can be heated to form a coke film attached to the inner wall of the pipeline. Then the pipeline anti-corrosion layer is formed. However, in the process of using the traditional online film-forming anti-corrosion device, the film-forming liquid is generally simply injected into the pipeline, so that the film-forming liquid cannot be well diffused on the surrounding inner walls of the pipeline, and then Affect the anti-corrosion effect of the pipeline, and the traditional online film-forming anti-corrosion device can only perform anti-corrosion treatment on one pipeline at a time, which greatly reduces the efficiency of anti-corrosion treatment
