Coke dry quenching oven coke discharge test method

Abstract

The invention discloses a coke dry quenching oven coke discharge test method. The first coke discharge value of a test point and testing discharge are inputted in a human-computer interface, a system control device reads current time, reads an in-oven charge level height value currently sent by a charge level detector mounted on the upper part of a coke dry quenching oven, and calculates current storage quantity, a corresponding first analog quantity is obtained according to the first coke discharge value through an analog quantity-corresponding coke discharge curve, the system control device outputs the first analog quantity to a vibrating discharger controller, a vibrating discharger starts to vibrate for discharge until the in-oven charge level declines to a certain value, the value is (in-oven storage quantity at the beginning of the test minus testing discharge) divided by coke weight per unit height, the system control device reads current time, and calculates test duration and coke discharge quantity, the coke discharge quantity substitutes for the first coke discharge to correspond to the first analog quantity, and the analog quantity-corresponding coke discharge curve is refreshed. The coke dry quenching oven coke discharge test method can simplify the check process of the coke discharge quantity, and still can be carried out in the normal production process of the coke dry quenching oven.

Description

technical field [0001] The invention relates to a method for checking the coke discharge amount of CDQ ovens in metallurgical coking, especially in the occasion where multiple CDQ ovens jointly discharge coke to a conveyor belt conveyor. Background technique [0002] In metallurgical CDQ coking, it is necessary to put the high-temperature red coke at 1000°C after carbonization in the coke oven into a CDQ oven (or CDQ furnace) for extinguishing, and put the high-temperature red coke into a closed CDQ furnace to be extinguished with air. Insulate and cool the high-temperature red coke by circulating nitrogen. The coke tank transports the high-temperature red coke from the coke oven into the furnace from the upper part of the CDQ furnace, and the coke cooled by nitrogen is continuously discharged out of the furnace from the lower part of the CDQ furnace. The coke discharge control of the CDQ furnace is an important index in the CDQ production process, which affects the pressur...

AI Technical Summary

Problems solved by technology

[0006] The prior art CDQ coke discharge coke discharge calibration method has the following major defects: Since the CDQ coke discharge vibration coke discharge device needs to be checked once every 1-3 months under normal conditions

In addition, after the device is overhauled or when it is found that there is a large difference between the set value and the actual coke discharge amount, it is also necessary to check the coke discharge amount.

1. In the prior art, the calibration of the amount of coke discharge in CDQ ovens needs to interrupt the normal production process for calibration, which affects the normal production

2. The calibration process of the amount of coke discharge is complex, involving many people, and time-consuming

3. It is necessary to use tools such as coke containers, scales, and transport vehicles, which are expensive
