Selective desulfurization method implemented based on high gravity reactor

A selective desulfurization method implemented based on a high gravity reactor, wherein the high gravity reactor comprises:

• a reactor having an inner chamber, and provided with an air inlet, an air outlet, a liquid inlet and a liquid outlet;
• a packed bed comprising a plurality of packing areas, wherein an annular groove is arranged between each two adjacent packing areas, an inner edge area of each of the plurality of packing areas forms an end effect area, the packed bed is arranged in the inner chamber of the reactor, the air inlet communicates with the packed bed, and the liquid inlet communicates with the packed bed;
• a guide module comprising a plurality of deflectors each being provided with a deflecting surface, the deflecting surface being configured for changing a flow direction of a desulfurizer liquid, wherein each annular groove is provided with several of the plurality of deflectors annularly and uniformly arranged therein;
• and
• a driving device configured for driving the packed bed to rotate;
• wherein the selective desulfurization method comprises the following steps:
• driving the packed bed to rotate through the driving device;
• introducing feed gas containing hydrogen sulfide into the reactor through the air inlet, and enabling the feed gas to enter the packed bed and move along a direction from an outer packing area of the plurality of packing areas to an inner packing area of the plurality of packing areas;
• and
• introducing a desulfurizer into the packed bed through the liquid inlet, and enabling the desulfurizer to move along a direction from the inner packing area to the outer packing area under an action of centrifugal force, and
• wherein the high gravity reactor further comprises a control module, a hydrogen sulfide detection device and a deflector driving module, the hydrogen sulfide detection device is configured for detecting a content of the hydrogen sulfide in the feed gas introduced into the reactor, the deflector driving module is configured for driving each of the plurality of deflectors to rotate, and the driving device, the hydrogen sulfide detection device and the deflector driving module are in communication with the control module.
