Cracking furnace pipe in-situ coating treatment heat treatment furnace

Abstract

The invention is mainly applied to the technical field of furnace pipe heating, and in particular, relates to a cracking furnace pipe in-situ coating treatment heat treatment furnace. The cracking furnace pipe in-situ coating treatment heat treatment furnace comprises a bottom frame, wall plates and a top cover plate to form a furnace cavity; portal frames are distributed in the furnace cavity; the portal frames are mounted on the bottom frame; two layers of cross beams are arranged on the portal frames; bottom electric heating chips are arranged between the adjacent portal frames, and are fixed on the bottom frame; the periphery of the bottom frame is the wall plates; the top cover plate is arranged at the tops of the wall plates; the wall plates on the front and back two sides and the top cover plate are provided with fire observing holes; staff access ports and process pipe outlets are respectively formed in the wall plates at the left and right two ends; and thermocouples, electric wire sleeves and side electric heating chips are respectively arranged on the inner sides of the wall plates on the front and back two sides. The cracking furnace pipe in-situ coating treatment heat treatment furnace can be used for heat treatment of pressure containers, can perform the heat treatment for equipment with different lengths and specifications through such forms as adding of separation plates and heightening, and can achieve multiple purposes.

Description

technical field [0001] The invention relates to a cracking furnace tube in-situ coating processing heat treatment furnace, which is mainly used in the technical field of furnace tube heating. Background technique [0002] The in-situ coating processing technology of cracking furnace tube is a patented technology developed by Beijing Research Institute of Chemical Industry. The coating component comes from the furnace tube substrate itself. The coating is firmly bonded to the substrate and has excellent anti-coking and anti-carburization properties. The in-situ coating can inhibit the coking of the cracking furnace tube of the ethylene device and prolong the effective production time of the device. Reduce energy consumption, increase the service life of furnace tubes, and improve the economic benefits of ethylene plants. After the BA1102 cracking furnace of Sinopec Yanshan Branch applied the in-situ coating suppression coking technology of the Beijing Research Institute of C...

AI Technical Summary

Problems solved by technology

[0006] 1. The heat treatment furnace is a one-time temporary installation. It will be dismantled after the heat treatment is completed, and repeated construction is required for the second treatment.

[0007] 2. Due to the temporary setting, the insulation effect is poor

It is difficult to strictly control the heating and cooling speed

[0008] 3. Temporary connection between pipes is required, and it needs to be cut off and re-polished after heat treatment, which is time-consuming and labor-intensive

low efficacy
