Abstract

The invention discloses a petroleum and petrochemical torch horizontal pipeline deformation compensation method and a petroleum and petrochemical torch horizontal pipeline deformation compensation device based on a rotary compensator. The method is characterized by comprising the following steps of: firstly, connecting two pipe ends at a corner of a torch horizontal pipeline or pipe ends of two parallel pipelines with a three-way pipe respectively; secondly, connecting two vertical straight ends of each three-way pipe with rotary compensators; and finally, communicating the rotary compensators at upper ends of two three-way pipes through an upper communicating pipe so as to circulate a gaseous medium, and communicating the rotary compensators at lower ends of the two three-way pipes through a lower communicating pipe so as to circulate a liquid medium; therefore, the whole petroleum and petrochemical torch horizontal pipeline is subjected to deformation compensation in a length direction, and the circulation of gaseous and liquid phase media is not influenced. The compensation system consists of an enclosed compensation system and a branch compensation system, which consist of three-way pipes and rotary compensators. The system has the advantages of long compensation distance, low 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 petroleum and petrochemical flare horizontal pipeline deformation compensation method and 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...
