Coke oven alpha value on-line detecting system and coke oven heating system regulating method

Abstract

The invention relates to a detecting device which is especially applicable to the detection on the excess air coefficient alpha value during the heating process of the coke oven, and the guide method on the adjustment of the heating cycle of the coke oven; the invention discloses a coke oven alpha value on-line detection system which comprises a gas analyzer and an alpha value on-line analysis module; the gas analyzer is arranged between a fume pipeline and a chimney; the fume with each gas content being analyzed is discharged after going through the chimney from the pipeline; the alpha value on-line analysis module is connected with the gas analyzer through a signal line; and the content data information of each gas analyzed by the gas analyzer is transferred to the alpha value on-line analysis module through the signal line to calculate the alpha value. The invention provides an on-line system to detect the alpha value of the coke oven, and a coke oven heating cycle adjustment method thereof, and can realize the alpha value on-line detection of the coke oven, promptly guide and improve the coke oven heating, and further accelerate the sufficient, comprehensive and reasonable burning of the heating gas. In a word, the invention has the advantages of simple structure, convenient preparation, easy installation, low cost, simple operation and good effectiveness.

Description

technical field [0001] The invention relates to a detection device, which is specifically applied to the detection of the α value of the excess air coefficient during the heating process of the coke oven and the guidance method for adjusting the heating system of the coke oven. Background technique [0002] Whether the combustion of coke oven heating gas is sufficient has a great impact on the energy saving and emission reduction of the coking plant. At present, no device or method for online detection of coke oven α value has been found at home and abroad. Most of them use manual detection of coke oven heating α value or only measure oxygen content. A small number of foreign and domestic manufacturers have adopted complex coke oven expert systems such as CCCS, ACCS (Japan, Baosteel), CPMS (Finland, Wuhan Iron and Steel) or CCMS (Wuhan Iron and Steel). Practice has proved that manual, hand-held detection and these expert systems only measure oxygen content and have the foll...

AI Technical Summary

Problems solved by technology

[0003] 1. Disadvantages of manual detection of α value: Manual detection of α value has the problems of heavy workload, low frequency, large error, and data lag. Timely guide coke oven heating

[0004] 2. Problems in the hand-held measurement of α value: First, due to the high temperature of the exhaust gas and the large amount of dust, the instrument is easy to break, and after a period of time, the measurement will be inaccurate

[0005] 3. The coke oven expert system only measures the problems of oxygen content: first, it cannot fully and accurately reflect the gas combustion situation; second, it cannot quantitatively guide the coke oven heating adjustment

In addition, various types of coke oven expert systems still have the problems of complex system, high investment, instability, large amount of maintenance, and high maintenance costs, and there is no specific guidance for coke oven heating adjustment
