Abstract

The invention discloses a lifting device for a reduction gas electric heater, which is mainly composed of a reduction section of a reforming reactor, a reduction gas electric heater, an outlet pipe of the electric heater, a lifting mechanism, a displacement sensor and a frame platform. The lifting mechanism is fixedly installed on the frame platform, the reducing gas electric heater is supported on the lifting mechanism, the outlet pipe of the electric heater is connected with the reducing section of the reforming reactor, one end of the displacement sensor is fixed on the frame platform, and the other end is fixed on the electric heater At the test point of the outlet pipeline, the displacement sensor is connected with the lifting mechanism through the control cable. The lifting device of the present invention arranges the reducing gas electric heater near the reducing section of the reforming reactor, makes the outlet pipeline of the electric heater as short as possible, and at the same time makes up for the deficiency of the conventional elastic compensation method in an intelligent follow-up manner, and solves the current problem. There are technical problems that have great potential safety hazards and difficult design.

Description

technical field

[0001] The invention relates to a lifting device used in a petrochemical reforming device, in particular to a lifting device for a reduction gas electric heater. Background technique

[0002] For a long time, the supporting type and layout scheme of the reducing gas electric heater connected to the reduction section of the reforming reactor in the continuous reforming unit using UOP technology and domestic technology has been a difficult point in engineering design. In order to control the temperature drop and pressure drop from the reduction gas electric heater to the hydrogen pipeline at the inlet of the reduction section, the patentee of the process package requires this part of the pipeline to be as short as possible, generally not exceeding 6 meters. The reduction gas electric heater adopts the principle of nearby arrangement. Since the reduction section and the reactor are coaxial and integrated structures, the overall height of the equipment is relativ...
