Design of CDQ circulating gas detection system based on STM32
Coke could have burning(solvation)reaction with CO2 and H2O(g)of circulating gas in the cooling tank of the CDQ system,which could affect the quality of coke and lead to a decrease in coke production.In order to investigate the impact of variations in the volume fractions of different components in the circulating gas of the CDQ system on the quality of coke,the detection system of CDQ circulating gas volume fraction was designed based on the STM32 single-chip microcomputer.The detection system mainly consisted of two parts:hardware and software.For the hardware,STM32F103RCT6 of STM32 series was selected as the main control chip of the system,H2,O2,CO2,CO and NO sensors were utilized to detect the gas volume fraction.For the software,the upper computer software was designed to generate the dynamic curves in real time from the gas volume fraction data detected by the sensors.Meanwhile,the data could be displayed on LCD and saved to SD card.Experimental verification confirmed that the detection system had good performance in practice,and in addition to connecting to the upper computer software,it could also be used as a portable device.
