Problems solved by technology

[0004] During the normal use of the ethylene cracking furnace, the fan is required to continuously blow gas into the ethylene cracking furnace to ensure the normal progress of the reaction in the ethylene cracking furnace. The existing ethylene cracking furnace usually has one fan for each furnace. Once the fan fails, it usually It is necessary to completely shut down the ethylene cracking furnace, which will affect the normal operation of the ethylene cracking furnace and affect the production efficiency of the ethylene cracking furnace

Abstract

The invention discloses an online hot standby method for a fan device of an ethylene cracking furnace, and belongs to the field of hot standby of fans of cracking furnaces. According to the online hotstandby method, a carrier of a fan system adopts a left-wheel type left-wheel rotary disc, the rotating mode is similar to the structure of a left-wheel type pistol bullet loading disc, the structureneeded by rotation is simple and reliable, faults caused by the structure are not prone to happening even in the long-time use process, faults of the fan system of the ethylene cracking furnace are not prone to happening, daily maintenance and hidden danger troubleshooting of technicians are facilitated, the fan body in the working position is easily and rapidly replaced, when the fan body of theethylene cracking furnace breaks down, the fan body can be replaced, maintained and repaired without shutting down the whole ethylene cracking furnace, normal work of the ethylene cracking furnace isnot prone to being affected, and the production efficiency of the ethylene cracking furnace is not prone to being affected.

Description

Technical field [0001] The present invention relates to the field of thermal cracking furnace blower equipment, and more particularly, relates to a method for hot standby ethylene cracking furnace blower means online. Background technique [0002] Ethylene cracking furnace for the processing of the cracked gas, the radiation chamber type double, single millisecond furnace and radiation chamber. Ethylene cracking furnace for ethylene production is the core of the device, the main role is natural gas, refinery gas, crude oil and naphtha, and other raw materials into cracked gas, ethylene and provided to other devices, the final processing into ethylene, propylene and various kinds of products. The level of technology and production capacity of ethylene cracking furnace, directly determines the size of the entire production, yield and product quality ethylene plant, so the ethylene cracking furnace in ethylene production and the entire petrochemical production have played a leading ...
