Method for detecting transverse oxygen content of burnt gas of coke oven and realizing device thereof

Abstract

The present invention relates to a method for detecting transverse oxygen content of burnt gas of a coke oven and a realizing device thereof. According to the method, the burnt gas which takes the shape of descending air current in each refrigerating chamber in an inverting period of coke oven is respectively sampled and executed with oxygen content analysis. The method can detect the oxygen content of exhaust gas in each burning chamber of coke oven. The transverse detection of oxygen content of exhaust gas of refrigerating chamber of whole coke oven is realized. Furthermore the longitudinal detection can be realized through calculating the average value of detection value of oxygen content of each refrigerating chamber. The low operating cost and maintenance volume can be ensured.

Description

technical field [0001] The invention relates to an automatic detection technology in the production process of the coking industry, in particular to a detection method for detecting the horizontal oxygen content of combustion waste gas in a coke oven and a device for realizing the detection method. Background technique [0002] The production process of the coking industry can be divided into three stages: coal preparation, coke oven and chemical production. Among them, the production process of the coke oven has the characteristics of nonlinearity, strong interference, and large lag, which makes some new automatic control methods unable to be used. It can be said that the backward detection technology hinders the improvement of the automation level of the coking industry. In the production process control of the coke oven, the temperature of the combustion chamber must be guaranteed first, and the energy consumption should be reduced secondly. To ensure the temperature of ...

Problems solved by technology

Although the laboratory technician post is set up to manually measure the oxygen content of the exhaust gas of each combustion chamber, however, this manual detection method can only detect the oxygen content of the exhaust gas of one combustion chamber within a day. For a 42-hole coke oven, It will take one and a half months to inspect all the combustion chambers

This manual detection method not only has low detection accuracy, but also has a long detection cycle, which has little effect on the production control of the coke oven
