A device for treating dioxin tail gas in fluorine chemical industry

Abstract

The application discloses a device for treating dioxin tail gas in fluorine chemical denitration, and relates to the technical field of dioxin tail gas treatment in fluorine chemical denitration, in particular to a device for treating dioxin tail gas in fluorine chemical denitration, which comprises a control cabin, an ultrafast quenching cabin, a dynamic injection mechanism, a catalytic reaction cabin and a dust removal cabin, and the cabins are sequentially communicated, and a high-temperature flue gas inlet is arranged in the side wall of the control cabin; the application realizes dynamic and accurate injection control, monitors the concentration of HF or SO2 in real time based on a concentration detection probe, adjusts the rotating speed of a coil pipe, drives a mixing arm to lift, links a material control plate to slide, controls the opening degree of a nozzle, dynamically matches the injection amount of lime or polyaluminum chloride with the concentration of pollutants, avoids the catalyst blockage problem caused by excessive injection, influences the reaction efficiency of the honeycomb catalyst unit and flue gas, and simultaneously solves the problem of nozzle blockage and no material output during the rotation of the mixing arm, thereby ensuring the long-term stable operation of the system.
