Embodiment Construction

[0014] The patent of the present invention is specifically described below in conjunction with the accompanying drawings and examples.

[0015] A kind of crude oil pipeline congealing pipe deblocking and dredging device of the present invention comprises: external motor (1); Rotary bottom closing frame (2); Rotary joint (3); Head drill (4); Drill bit (5); Crude oil pipeline ( 6); the crude oil coagulation part (7); the stirrer (8); the stirring head (9); the heater (10); The swivel joint (3) and the drill bit (5) in the crude oil pipeline (6) rotate, and at the same time, the external motor (1) connects the heating tube (11) in the swivel joint (3) through a circuit, so that the heater (10) works, and the condensation tube Crude oil softens when heated.

[0016] According to the method and device for unclogging and unclogging of coagulation pipes in crude oil pipelines, the swivel (3) is composed of 12 sets of identical agitators (8) and 12 sets of identical heaters (10) even...

Abstract

In the heat conveying process of a crude oil pipeline, the pipeline needs to be maintained and overhauled periodically, or conveying needs to stop temporarily when accidents happen to the pipeline, so that serious consequences, that is coagulation and blocking of the pipeline, may occur in the restart process of conveying or after leakage accidents happen to the pipeline, the serious consequences are undoubtedly disastrous to the crude oil pipeline, and if plugging relief or dredging cannot be performed on a crude oil coagulation section, the coagulation section may be longer and finally a whole pipeline system is paralyzed and scrapped. The invention relates to a plugging relief and dredging method device for the crude oil pipeline. The device mainly comprises an external motor (1), a drill bottom folding frame (2), a rotary joint (3), a head drill (4), a drill bit (5), the crude oil pipeline (6), a crude oil coagulation part (7), a stirrer (8), a stirring head (9), a heater (10) and a heating pipe (11). The device is mainly applied to plugging relief and dredging after crude oil pipeline coagulation.

Description

technical field [0001] The invention relates to a method and device for unclogging and dredging a condensation pipe of a crude oil pipeline. An external motor is used to drive the internal rotor of the pipeline to rotate through a shaft, and at the same time, the external motor transmits the electric energy of the rotor so that the rotor heating tube emits heat to heat the condensed product. Crude oil belongs to the technical field of crude oil pipeline transportation. Background technique [0002] Crude oil pipelines have minimum outbound oil temperature and minimum delivery volume restrictions during heating and transportation. A very serious consequence that will occur in the process of shutting down and restarting is that the pipeline will be blocked by condensation pipes, which is undoubtedly disastrous for crude oil pipelines. If the blockage of the crude oil condensation section cannot be unblocked in time, it is very likely that the condensation will be blocked Long...
