Abstract
Control system of desulfurization of sintering gas falls into the desulfurization technology of sintering machine in the steel industry, applicable to desulfurization system of wet sintering gas. Under the system, the on-site data is sent to the central processing unit of the control cabinet for analysis via the sensor so as to effectively control the operating parameters of the equipment to match gas conditions with the working conditions of induced draft fan, oxidation compressor, lime milk pump, slurry circulating pump, gas heat exchanger and so on. Steel slag has strong alkalinity, which may be used as the raw material of desulfurizer to neutralize SO2 in the exhaust gas. Its operating cost is far lower than that of limestone as desulfurizer. Meanwhile, it has solved the problem of the comprehensive utilization of steel slag in conformity with the national industrial policy and with economic and social efficiency. It features accuracy, timely control and stability.
