A circulation is established between the oxidation tank body 1 and the desulfurization tower to ensure that the desulfurization absorption liquid circulates continuously in the system. At the same time, the desulfurization tower concentration section is replenished to ensure The system operates stably. At the same time, the oxidation fan 54, the air inlet pipe 51 cooperate with the flow meter 52 and the second solenoid valve 53 to pass the oxidation air into the oxidation zone 13 of the oxidation tank body 1. The oxidation air first flows into the square groove 61, then enters the multiple annular grooves 62, and finally flows into the desulfurization absorption liquid in the oxidation zone 13 through the multiple air holes 63. The gas-liquid two phases are fully contacted under the high-speed turbulent state to carry out oxidation regeneration reaction, increase the gas-liquid contact area and extend the air residence time.

The oxidized air is discharged from the oxidation zone 13 through the exhaust pipe 55 and the third solenoid valve 56 to maintain the air pressure in the oxidation zone 13. When the liquid level of the desulfurized liquid in the oxidation zone 13 drops, the air pressure in the oxidation zone 13 decreases, and the air pressure difference between the oxidation zone 13 and the absorption zone 12 increases, driving the desulfurized liquid in the absorption zone 12 to flow into the oxidation zone 13.

The second liquid outlet 45 and the second liquid outlet pipe 46 cooperate with the auxiliary absorption pump 47 and the auxiliary solenoid valve 48 to drain the desulfurization absorption liquid in the oxidation zone 13 to the desulfurization tower at the set flow rate to ensure the liquid level difference between the absorption zone 12 and the oxidation zone 13. The desulfurization liquid in the absorption zone 12 and the oxidation zone 13 is exchanged through the exchange pipe 14, and the desulfurization liquid levels in the absorption zone 12 and the oxidation zone 13 are in a balanced state.
