Abstract

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.

Description

technical field [0001] The invention relates to an equipment technology for an alkane dehydrogenation project, in particular to a regeneration gas pipeline device at the outlet of a high-temperature fan for an alkane dehydrogenation project. Background technique [0002] In the field of alkane dehydrogenation products, many process pipelines are mostly high-temperature medium pipelines. For example, in the process conditions of the present invention, the design temperature of the high-temperature regeneration gas pipeline is 650°C. Generally, ordinary materials cannot meet the requirements of long-term operation at all. The pipelines used The material is extremely special, and the requirements for the pipe material in the process are all imported N06600 material, which is expensive. Among them, with the increase of the production time of the device, the regenerative gas pipeline at the outlet of the high-temperature fan will continue to work under high-temperature conditions...
