Description

Rotary propelling pipe cleaner for gas pipeline

Technical Field

The utility model relates to a pipeline pigging device in the process of natural gas and oil transportation, which is a rotary propulsion tube cleaner for a gas pipeline.

Background

The pig is an important tool indispensable to the pipeline industry. In the cleaning work of the oil and gas pipeline, sundries in the pipeline, including natural gas hydrate, household garbage, accumulated sediments, industrial wastes after construction, dead animal bodies and the like, can be cleaned by a pipe cleaner, scrap iron or burrs in the pipeline can be cleaned, and sometimes an owner also requires the pipe cleaner to check the ovality and the pipe wall corrosion condition of the pipe. When the pipeline is connected in a full-line mode, hydraulic tests are conducted on the pipeline. During the test, the individual steps of filling, draining and drying were also not pig-fed, but during commissioning and driving of the liquid transport pipeline, the liquid was also filled with pig-fed liquid. With the common commercial pig, the pipeline pig typically fails or becomes clogged while operating within the pipeline for a variety of reasons, such as: the pipe cleaner is clamped at the elbow, and the removed sediment is accumulated in front of the pipe cleaner to push the fluid to flow around the pipe cleaner, bend and deform the pipe cleaner and the like. The blocking of the pipe cleaner causes the flow of the pipeline to be reduced, even the whole pipeline is blocked, and serious consequences are caused. Although new points for improving the defects of the pipe pig exist so far, most of the pipe pigs have various defects, for example, a jet flow pipe pig suitable for a large-caliber gas pipeline, namely a product of patent No. CN2010207004797, improves a pipe pig brush head into a spherical structure, reduces the friction resistance, and greatly weakens the washing capacity of the pipe pig for refractory dirt. There is also a rotary brush pipe cleaner, the product of patent No. CN105665383A, which improves the operation mode of pipe cleaner to rotate pipe cleaner and improve the washing ability, but the structure of the rotary machine is too complex, and the manufacturing cost and maintenance cost are very high. The same type of pipe cleaner with a propeller and a lubricatable pipe wall, namely the product with the patent number of CN208033224, also applies the rotation mechanism of the pipe cleaner, and is provided with the propeller and the jet device, but the manufacture is also complex, and the service life of the propeller device is difficult to ensure in the complex pipeline cleaning process, so the maintenance cost of the product is worried. In summary, it is critical that the pipe cleaner not only needs to thoroughly solve the blocking problem of the pipe cleaner, but also needs to ensure high washing and brushing capability of the pipe cleaner, and simultaneously, the manufacturing cost and the maintenance cost are low. Therefore, based on the background above, the utility model discloses the product will show one kind and can clean debris in the pipeline comparatively thoroughly, can be in the same direction as smooth pipe wall simultaneously, reduce the resistance, and can reduce the cost of manufacture of dredging pipe ware and cost of maintenance's dredging pipe ware again.
