Embodiment 1
[0037] An online hot standby method for an ethylene cracking furnace fan unit, the main steps of which include:
[0038]S1. Fan monitoring. The fan for ventilation of the ethylene cracking furnace is set as a working position fan, and the sensor loaded in the fan is used to monitor the working position fan speed and working temperature in real time. The sensor settings and monitoring methods are based on this The well-known technology of those skilled in the art, so it is not described in detail in this application, those skilled in the art can easily complete the setting and use of the sensor according to the existing technology in the field;
[0039] S2. Fan replacement. When the working time of the fan reaches the preset standard or the speed of the fan fails to reach the preset standard for a long time, the fan at the working position is replaced while the ethylene cracking furnace is not shutting down as a whole, and technicians are arranged to repair the fan from the fan....

The invention discloses an on-line hot backup method for a fan device of an ethylene cracking furnace, belonging to the field of hot backup of cracking furnace fans, and an online hot backup method for a fan device of an ethylene cracking furnace. The rotation method of the turntable is similar to the structure of the revolver pistol loading disk. The structure required for rotation is relatively simple and reliable. Even in the long-term use process, it is not easy to cause failure due to the structure itself, and it is not easy to cause ethylene cracking furnace. When the fan system of the ethylene cracking furnace fails, it is convenient for technicians to carry out daily maintenance and hidden danger investigation, and it is easy to realize the rapid replacement of the fan body in the working position. The replacement, maintenance and repair of the main body of the fan can be realized, and the normal operation of the ethylene cracking furnace is not easily affected, and the production efficiency of the ethylene cracking furnace is not easily affected.
Description
technical field [0001] The invention relates to the field of thermal backup of cracking furnace fans, and more specifically relates to an online thermal backup method for an ethylene cracking furnace fan device. Background technique [0002] Ethylene cracking furnaces are used to process cracked gas, and there are double radiation chambers, single radiation chambers and millisecond furnaces. The ethylene cracking furnace is the core equipment of the ethylene production unit. Its main function is to process various raw materials such as natural gas, refinery gas, crude oil and naphtha into cracked gas, and provide it to other ethylene units, and finally process it into ethylene, propylene and various kind of by-product. The production capacity and technology of the ethylene cracking furnace directly determine the production scale, output and product quality of the entire ethylene plant. Therefore, the ethylene cracking furnace plays a leading role in the ethylene production ...
