Abstract

The invention discloses a catalytic flue gas treatment device and a yellow phosphorus tail gas purification system, aiming at solving the technical problem of reducing the potential safety hazard of oxygen supplementation to flue gas to be treated when the catalytic flue gas treatment device runs. Comprising a reaction system, a regenerated liquid circulating system and a flue gas conveying system, the system further comprises an oxygen supplementation system, the oxygen supplementation system comprises a second air blower, an airflow adjusting device and an oxygen supplementation gas distribution pipe network, and the second air blower and the airflow adjusting device are connected with the reactors through the oxygen supplementation gas distribution pipe network. The flow of the airflow generated by the second air blower is adjusted through the airflow adjusting device, then oxygen supplementing gas is formed and enters the to-be-treated flue gas of the corresponding reactor, and the oxygen concentration in the oxygen supplementing gas is larger than the oxygen concentration in the to-be-treated flue gas before the oxygen supplementing gas is mixed with the to-be-treated flue gas. Potential safety hazards possibly caused by mixed oxygen supplementation outside the reactor are avoided.
