[0052] Check that the feed pipe 27, the discharge pipe 30, the catalyst pipe 28, the oxygen pipe 29 and other pipes are firmly connected and there is no leakage.

[0053] Check that the valve plates (first baffle plate 23 and second baffle plate) are in a closed state to ensure that the bottom opening of the filter sleeve 22 is well sealed.

[0054] Check the connection and fixation of the drive member (rotating motor 7) to ensure that it can work normally.

[0058] Check that the legs are firmly installed and can stably support the entire device.

[0059] 2. Injecting desulfurization liquid and adding catalyst and oxygen

[0060] The desulfurized liquid to be treated is slowly injected into the reaction barrel 2 through the feed pipe 27 .

[0061] When the desulfurized liquid passes through the filter sleeve 22 , the impurities therein are intercepted by the filter sleeve 22 , thereby ensuring that the desulfurized liquid entering the lower part of the reaction barrel 2 is relatively pure.

[0062] An appropriate amount of catalyst is injected into the reaction barrel 2 through the catalyst tube 28 .

[0063] The injection amount of the catalyst can be adjusted according to the amount of desulfurization liquid and the processing requirements.

[0064] Oxygen is injected into the reaction barrel 2 through the oxygen pipe 29 .

[0065] The amount of oxygen injected should be controlled according to the needs of the catalytic oxidation reaction.

[0066] 3. Catalytic oxidation reaction stage

[0067] The rotating electric machine 7 is started.

[0068] The rotating motor 7 drives the rotating shaft 8 to rotate, and the driving gear 9 on the rotating shaft 8 meshes with the gear ring 4 on the outer wall of the reaction barrel 2, thereby driving the reaction barrel 2 to start rotating.

[0069] At the same time, the first bevel gear 10 on the top of the rotating shaft 8 drives the second bevel gear 12 to rotate, thereby rotating the rotating shaft 11. The third bevel gear 13 on the rotating shaft 11 drives the fourth bevel gear 15 on the top of the stirring shaft 14 to rotate, thereby driving the stirring shaft 14 to rotate in the opposite direction to the reaction barrel 2.

[0070] The rotation of the reaction barrel 2 and the stirring shaft 14 allows the desulfurization liquid, the catalyst and the oxygen to be fully mixed.

[0071] The reverse stirring of the stirring blade 16 accelerates the dissolution of the catalyst, increases the reaction speed of the desulfurization liquid, and promotes the catalytic oxidation reaction.

[0072] 4. Discharging the treated desulfurization liquid and cleaning the reaction barrel 2 stages

[0073] When the desulfurization liquid is treated, the discharge pipe 30 is opened to discharge the treated desulfurization liquid out of the reaction barrel 2 .

[0074] The stirring shaft 14 continues to rotate, driving the connecting rod 17, the limiting plate 18, the scraper 20 and other components to rotate.

[0075] The scraper 20 is always close to the inner wall of the reaction barrel 2 under the action of the support spring 21, and automatically cleans the inner wall of the reaction barrel 2 to remove the attachments on the inner wall.

[0076] 5. Cleaning and filtering impurities

[0077] Turn off the rotating motor 7, and after the equipment stops running, pull the first guide rod 24 and the second guide rod respectively through the first handle 26 and the second handle.

[0078] The first guide rod 24 drives the first partition plate 23 to move, and the second guide rod drives the second partition plate to move, thereby releasing the valve plate from blocking the bottom opening of the filter sleeve 22 .

[0079] Under the action of gravity, the impurities intercepted in the filter sleeve 22 fall down.

[0080] The impurities are discharged from the reaction barrel 2 through the discharge pipe 30, completing the cleaning of the filtered impurities.

[0081] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
