Method for indirectly measuring center temperature of coke cake of coke oven

Abstract

The invention relates to a method for indirectly measuring the center temperature of a coke cake of a coke oven. The method comprises the following steps: in the coke pushing process, controlling a coke pushing rod to pause for multiple times by matching the temperature measuring personnel with a coke pushing vehicle driver to enable the front part, the middle part and the rear part of the coke cake to respectively stay at a coke guide grid, and forming a red hot coke cake section; controlling an infrared thermal imager to aim at the section of the red hot coke cake to carry out photographingby the temperature measuring personnel, and recording the temperature information of the coke cake in the form of a thermal imaging electronic image; and processing the temperature information by using computer software, and converting the temperature information into coke cake center temperature data. Compared with a traditional method, the provided method has the following advantages: the workload and labor intensity for measuring the center temperature of the coke cake are greatly reduced, and the method has the advantages of being accurate in measured data, easy and rapid to operate and high in safety.

Description

technical field [0001] The invention relates to the technical field of coke oven production, in particular to a method for indirectly measuring the center temperature of a coke oven coke cake. Background technique [0002] Coke is produced by high-temperature dry distillation in the coke oven carbonization chamber with coal materials. Coke cake is an integral substance formed after the coal material loaded into the coke oven carbonization chamber is subjected to coking high temperature conditions for a certain period of time, and its central temperature is an important coking thermal index for judging whether the coke is mature or not. [0003] The traditional method of measuring the center temperature of the coke cake belongs to the direct measurement method, that is, after the coal material has just been loaded in the carbonization chamber, the temperature measuring personnel insert the coal filling hole vertically into the coal material along the center of the carbonizati...

AI Technical Summary

Problems solved by technology

[0008] 2) There is a risk of electric shock in the operation of inserting the coke cake tube on the top of the furnace;

[0009] Because there is a coke oven vehicle grinding wire rack on the top of the coke oven, the coke cake tube needs to be erected when inserting the coke cake tube on the top of the furnace, and the risk of electric shock is high

[0010] 3) There is a risk of burns in the operation of pulling out the coke cake tube;

[0011] The temperature of the coke tube pulled out after the measurement of the coke cake temperature is about 1000°C, which is likely to cause burns to the temperature measurement personnel and pose a safety hazard

[0012] 4) High labor intensity and large number of workers;

[0014] In summary, using the traditional method of measuring the center temperature of coke cake is time-consuming and laborious, and the safety is poor
