Deformation Compensation System for Closed Petroleum and Petrochemical Flare Horizontal Pipeline Based on Rotary Compensator

Abstract

A closed-type petroleum and petrochemical flare horizontal pipeline deformation compensation system based on a rotary compensator is characterized in that it includes at least one closed rotary compensator installed on the flare horizontal pipeline, and the closed rotary compensator consists of four rotary compensators The compensator (3) is composed of two vertically installed tee pipes (2), the upper connecting pipe (4) and the lower connecting pipe (5). The corresponding ports of the horizontal torch pipe (1) of the same straight line are connected, and the two vertical nozzles of each three-way pipe (2) are respectively connected with a rotary compensator (3), and the upper ends of the two three-way pipes (2) The rotary compensator (3) is connected through the upper connecting pipe (4) to form a pipeline for the circulation of the gaseous medium, and the rotary compensator (3) located at the lower end of the two tee pipes (2) is connected through the lower connecting pipe (5) to form a pipeline for the circulation of the gaseous medium. Pipelines for the flow of liquid media. The invention has the advantages of long compensation distance, small investment, safety and reliability.

Description

technical field [0001] The invention relates to a petrochemical technology, especially a flare gas transmission pipeline technology used in the petrochemical industry, specifically a rotary compensator capable of both axial length compensation and gas-liquid separation The closed type oil and petrochemical flare horizontal pipeline deformation compensation system. Background technique [0002] At present, in the petroleum and petrochemical industry, the toxic and harmful gases that cannot be recycled are generally used for harmless treatment by burning. Therefore, the torch is an essential environmental protection treatment equipment for petroleum and petrochemical enterprises. Due to the large amount of gas to be processed, the gas contains a large amount of corrosive liquid, and the distance between the flare head and the gas production workshop is relatively large, therefore, the diameter of the existing flare gas pipeline is large, and all corrosion-resistant Made of st...
