High-temperature fan outlet regeneration gas pipeline device applied to alkane dehydrogenation project

The invention discloses a high-temperature fan outlet regeneration gas pipeline device applied to an alkane dehydrogenation project. The device comprises a first vertical pipe section which is connected with a high-temperature regeneration gas outlet and extends horizontally, a second horizontal pipe section which is horizontally arranged, a third vertical pipe section which is vertically arranged, a fourth horizontal pipe section which is horizontally arranged, a fifth horizontal pipe section which is horizontally arranged and a sixth vertical pipe section which is vertically arranged, wherein the tail end of the sixth vertical pipe section is connected with the inlet of a high-temperature regeneration gas electric heater; a universal angle type ripple compensator, a variable spring lifting frame, a constant-force spring bracket, a rigid pipeline bracket, a rigid pipeline guide frame, a four-way guide frame, a north-south two-way guide frame and a rigid pipeline bracket are arranged on the whole pipeline. According to the high-temperature fan outlet regeneration gas pipeline device applied to the alkane dehydrogenation project, the pipeline is short and straight, few in corners, low in pipeline pressure drop loss, high in flexibility, stable in operation and uniform in stress.
