[0002] Coke oven baking is the important and complex technological process of the transition from construction to production, and the quality of the baking has a vital influence on the service life of the coke oven. The key of the baking is to require each part of the coke oven to be heated uniformly according to the plan and the proportion, and then to expand uniformly. Therefore, a large number of temperature sensors need to be installed during the baking of the coke oven.
[0003] Taking a 70-hole 7.65m coke oven as an example, about 300 thermocouples need to be installed for temperature monitoring in the top area of the coke oven, and these thermocouples need to be installed before the baking and removed before the coke oven is converted to normal heating. Under normal circumstances, the heating period from ignition to normal heating of a coke oven is about 50-80 days, that is, about 300 thermocouples need to be installed and removed for 50-80 days of temperature measurement during the baking.
[0004] At present, various types of temperature transmitters still generally use compensation lead connection method to connect with thermocouple sensors. When using the compensation lead connection method for installation and removal, the process of bridge erection, wiring, wiring, debugging, etc. needs to be experienced. Due to the construction of the top of the coke oven during the baking process, the baking process of the coke oven is not tight, and the compensation lead used is usually burned, cut, damaged and cannot be reused when removed in an emergency.
[0005] At the same time, due to the excessive compensation lead layout and the lack of effective anti-interference means, the compensation lead is often damaged or interfered by various electromagnetic signals during the construction process during the baking process. Moreover, when the compensation lead is used for connection during the baking process, it is usually difficult to achieve full coverage of the compensation lead, resulting in a large error in the temperature collected by the baking temperature measurement system.
