Automatic measuring method and automatic measuring system for temperature of vertical flue of coke oven

Abstract

The invention relates to an automatic measuring method and an automatic measuring system for temperature of a vertical flue of a coke oven. Through a temperature measuring device walking track compiling process, a combustion chamber positioning process, a noise bridge brick identification process and a continuous temperature measuring process, the temperature of each vertical flue is determined according to a temperature curve which is measured in the continuous temperature measuring process, the number of the combustion chamber, a time stamp and nose bridge brick identification information. According to the automatic detecting method and the automatic detecting system, existing equipment in a coke oven production system is sufficiently utilized, such as a carbonizing chamber code disc and a coal charger track; three movable temperature measuring devices are utilized for simultaneously measuring the temperatures of the vertical flues in different areas; a ground PLC workstation compiles the temperature measuring device walking track and makes a walking plan according to a coke pushing plan; continuous temperature measurement is performed on the vertical flues periodically on the condition that normal operation of a coke oven coal charger is not affected; and furthermore opening or closing of a fire observing hole cover is not required in the temperature measuring process, thereby greatly improving temperature measuring efficiency and furthermore improving timeliness in performing tempering on the coke oven.

Description

technical field [0001] The invention relates to the technical field of coking production, in particular to an automatic detection method and system for the temperature of a coke oven vertical flue, which can automatically locate a combustion chamber, measure a standard flue temperature, and upload data to a ground PLC workstation. Background technique [0002] Coke oven temperature management is a key link in coking production, and the furnace temperature is directly related to the quality of coke. Therefore, the measurement of coke oven flue temperature has always been an important daily work content in coke oven production. [0003] Initially, coking plants generally adopted the practice of manually collecting the temperature of the vertical flue with an infrared instrument, which was labor-intensive and the collected data was inaccurate. Due to many problems such as the randomness of manual detection and the high uncertainty of detection points, the manually collected fl...

Problems solved by technology

Due to the large number of fire holes, the auxiliary time of the temperature measurement process is too long, not only the measurement efficiency is low, but also the normal production rhythm of the coke oven may be affected
