Technical Field

[0002] In the petroleum industry, dewaxing is crucial for ensuring smooth pipeline operation, improving transportation efficiency, and reducing operating costs. During transportation, factors such as temperature and pressure changes and crude oil composition can cause a wax layer to form on the inner wall of the pipeline. This reduces the flow area, decreases transportation capacity, increases transportation resistance and energy consumption, and in severe cases, can cause pipeline blockage, affecting production. However, existing oil pipeline dewaxing equipment still has certain shortcomings, such as: Application CN202411257680.5, entitled "A Wax Removal Device for Oil Pipelines," comprises: a cylinder, with a rotating drum coaxially rotatably connected to one end of the cylinder; radially extending telescopic rods are provided on both sides of the rotating drum; one end of the telescopic rod passes through the side wall of the rotating drum and is slidably connected to the side wall of the rotating drum; a wax removal ball is provided on the other end of the telescopic rod; multiple spray holes are provided on the outer wall of the wax removal ball; a driving device is provided inside the cylinder; a wax removal agent transmission device is provided inside the rotating drum; and the driving device and the wax removal agent transmission device are connected. This device cannot effectively recover waste wax when cleaning oil pipelines, thus wasting resources and failing to meet usage requirements.

[0019] 1. When in use, the staff places the equipment bucket inside the oil pipeline. At this time, the roller assembly installed in the No. 2 clamp is against the inner wall of the oil pipeline. Through the elastic action of the spring reset device installed in the No. 2 clamp, the roller assembly is tightly attached to the inner wall of the oil pipeline, ensuring the stability of the equipment bucket inside the oil pipeline. 2. Then start the motor and air pump. The motor drives the rotating rod to rotate, and the rotating rod drives the scraper and cutting blade assembly to rotate simultaneously. Through the spring reset device in the No. 1 cassette, the scraper is made to fit tightly against the inner wall of the oil pipeline to scrape and cut the wax layer attached to the inner wall of the pipeline. The design of the scraper allows it to penetrate deep into the wax layer and effectively peel off the wax layer. 3. At the same time, the cutting blade assembly further breaks down the large pieces of wax scraped off, making it easier for subsequent processing and recycling; under the action of the suction pump, the dust hood generates negative pressure, sucking the fine wax layer that has passed through the cutting blade assembly into the equipment barrel, realizing the recovery of the wax layer; finally, the wax layer accumulated in the equipment barrel is taken out through the material gate. 4. The wax layer inside the oil pipeline is preheated by a low-power heater. The preheating process gradually softens the wax layer, which further improves the scraping and cutting efficiency of the scraper and cutting blade assembly. At the same time, preheating also helps to reduce the adhesion of the wax layer to the oil pipeline during the wax removal process, making the cleaning process smoother. 5. The solvent is evenly sprayed onto the wax layer on the inner wall of the oil pipeline using a solvent sprayer. The solvent can effectively penetrate into the wax layer, accelerating the softening and decomposition of the wax layer, thereby improving the wax removal efficiency of the scraper and cutting blade assembly.
