Pipeline release control system

Abstract

The disclosure relates to a discharge control system of an oil pipeline, and belongs to the supporting technical field of detection implementation in the oil pipeline. The discharge control system includes a horizontal pipe, a vertical pipe, an anti-spray spherical cover, a three-way pipe, multiple return pipes and multiple oil collection tanks, wherein: the discharge control system is used for reactivation when the transportation is shut down and sealed. When the oil pipeline is inspected internally, it is installed on the outlet of the oil pipeline; the horizontal pipe is installed on the outlet of the oil pipeline, and the nozzle of the horizontal pipe far away from the outlet of the oil pipeline is connected to the vertical pipe through a 90° thermal bend; Installed at the nozzle of the vertical pipe away from the horizontal pipe; the anti-spray spherical cover is fixed on the tee pipe through the support frame and covered on the tee pipe; one end of each return pipe is fixed on the anti-spray spherical cover On the edge of the piece; each oil sump is respectively arranged below at least one return pipe. By adopting the present disclosure, the pollution to the surrounding environment caused by the sprayed residual oil can be effectively reduced.

Description

technical field [0001] The present disclosure relates to the technical field of detection implementation in oil pipelines, and in particular to a pipeline discharge control system. Background technique [0002] When the oil pipeline is restarted after the shutdown, it is necessary to clean up the residual oil inside the oil pipeline and detect whether there is metal loss on the inner and outer walls of the oil pipeline. [0003] Usually, the method of injecting nitrogen to push the pipeline pig and the internal detector is used to clean and detect the oil pipeline. Specifically, the technician puts a pipe for detecting the inner and outer walls of the oil pipeline at a nozzle of the oil pipeline, which can be called the inlet. The metal loss detector is equipped with sealing devices at the front and rear ends of the detector, and then injects nitrogen gas into the oil pipeline from the inlet of the oil pipeline, so that the nitrogen pushes the detector to move toward the out...

AI Technical Summary

Problems solved by technology

[0005] Nitrogen at the outlet of the oil pipeline will push the residual oil out, and due to the relatively high air pressure, the range of the residual oil sprayed outward is also relatively large, causing greater pollution to the surrounding environment of the oil pipeline outlet
