Among them, the oxidation tank used in the desulfurization tower is mainly used for the regeneration treatment of the desulfurization liquid.

[0045] Working principle and usage process of the present invention: The liquid inlet pipe 31, in cooperation with the first pump body 32 and the first solenoid valve 33, pumps the desulfurization absorption liquid in the desulfurization tower into the absorption area 12 of the oxidation tank main body 1. The desulfurization absorption liquid in the absorption area 12 flows into the oxidation area 13 through the exchange pipe 14. The liquid level of the desulfurization absorption liquid in the oxidation area 13 is higher than the bottom end of the exchange pipe 14, and the liquid level of the desulfurization absorption liquid in the absorption area 12 is higher than the top end of the exchange pipe 14. The first liquid outlet 41 and the first liquid outlet pipe 42, in cooperation with the main absorption pump 43 and the main solenoid valve 44, pump the desulfurization absorption liquid in the absorption area 12 into the desulfurization tower. The second liquid outlet 45 and the second liquid outlet pipe 46, in cooperation with the auxiliary absorption pump 47 and the auxiliary solenoid valve 48, pump the desulfurization absorption liquid in the oxidation area 13 into the desulfurization tower. A cycle is established between the oxidation tank main body 1 and the desulfurization tower to ensure that the desulfurization absorption liquid continuously circulates in the system, while replenishing the concentrated section of the desulfurization tower to ensure the stable operation of the system. At the same time, the oxidation blower 54 and the air inlet pipe 51, in cooperation with the flow meter 52 and the second solenoid valve 53, introduce oxidation air into the oxidation area 13 of the oxidation tank main body 1. The oxidation air first flows into the square tank 61, then enters a plurality of annular tanks 62, and finally flows into the desulfurization absorption liquid in the oxidation area 13 through a plurality of air holes 63. The gas-liquid two phases are in full contact under the state of high-speed turbulence to carry out the oxidation regeneration reaction, increasing the gas-liquid contact area and prolonging the air residence time. Ammonia water is the absorbent for ammonia-based desulfurization. The ammonia water enters the absorption area 12 from the ammonia inlet pipe 15 to absorb sulfur dioxide in the desulfurization absorption liquid. The desulfurization absorption liquid in the absorption area 12 and the desulfurization absorption liquid in the oxidation area 13 are exchanged through the exchange pipe 14. The excess oxidation air is discharged from the oxidation area 13 through the exhaust pipe 55 and the third solenoid valve 56. By combining physical partitioning and chemical partitioning, the component stratification is ensured.
[0046] Refer to Figure 3, the intake pipe 51 and the oxidation blower 54 cooperate with the second solenoid valve 53 to deliver gas to the oxidation zone 13. The oxidation 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 desulfurization liquid in the oxidation zone 13 drops, the air pressure in the oxidation zone 13 decreases, and the pressure difference between the oxidation zone 13 and the absorption zone 12 increases, driving the desulfurization liquid in the absorption zone 12 to flow into the oxidation zone 13. The liquid inlet pipe 31 and the first pump body 32 cooperate with the first solenoid valve 33 to drain the desulfurization liquid into the absorption zone 12 at a set flow rate. The first liquid outlet 41, the first liquid outlet pipe 42 cooperate with the main absorption pump 43 and the main solenoid valve 44 to drain the desulfurization absorption liquid in the absorption zone 12 to the desulfurization tower at a set flow rate to maintain the liquid level of the desulfurization liquid in the absorption zone 12. The excess oxidation air is discharged from the oxidation zone 13 through the exhaust pipe 55 and the third solenoid valve 56. The intake pipe 51 and the oxidation blower 54 cooperate with the second solenoid valve 53 to deliver gas to the oxidation zone 13 to maintain the air pressure in the oxidation zone 13. The second liquid outlet 45, 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 a 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 liquid levels of the desulfurization liquid in the absorption zone 12 and the oxidation zone 13 are in a balanced state.
[0047] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention.
