Description

Technical Field

[0001] This utility model relates to the field of Fenton fluidized bed technology, and in particular to an integrated circulating Fenton fluidized bed. Background Technology

[0002] The Fenton fluidized bed reactor, also known as the Fenton oxidation tower, Fenton reactor, Fenton fluidized bed, or Fenton equipment, is an inorganic chemical reaction. The process involves a mixed solution of hydrogen peroxide (H₂O₂) and ferrous ions (Fe²⁺) oxidizing many known organic compounds, such as carboxylic acids, alcohols, and esters, into inorganic forms. This reaction has a high capacity for removing recalcitrant organic pollutants and is widely used in the treatment of wastewater from dyeing and printing, oily wastewater, phenolic wastewater, coking wastewater, nitrobenzene-containing wastewater, and diphenylamine wastewater.

[0003] The Fenton reaction produces reaction residue that remains inside the reaction vessel. In traditional integrated circulating Fenton fluidized beds, the vessel is usually sealed during the reaction, so the reaction residue remains inside the vessel. The residue is usually treated after the reaction is completed or periodically, which often affects the progress of the work.

[0004] Therefore, in order to solve the aforementioned technical problems, an integrated circulating Fenton fluidized bed is needed. Utility Model Content

[0024] Preferably, a lifting ring (not shown in the figure) is provided on the top of the substrate 1, which facilitates the relevant personnel to lift the present invention by means of lifting equipment and the lifting ring.

[0025] In another possible embodiment of the present invention, support rods (not shown in the figure) are provided at the four corners of the bottom of the substrate 1 to effectively raise the height of the present invention, thereby facilitating the operation of the present invention by the staff.

[0026] It should be noted that a frustum 21 is provided at the bottom of the reaction vessel 2, and one end of the discharge pipe 4 is located at the top of the frustum 21, which facilitates the sliding of residue along the upper surface of the frustum 21.

[0027] The impurity removal device 3 includes: a second drive motor 31, a guide rod 32, a mounting ring 33, a second scraper 34, and a limiting plate 35.

[0028] The second drive motor 31 is mounted below the reaction vessel 2 via a mounting bracket. The guide rod 32 is axially mounted at the bottom of the reaction vessel 2, with one end of the guide rod 32 passing through the frustum 21 and extending outwards, and the other end passing through the reaction vessel 2 and connected to the drive end of the second drive motor 31. Multiple mounting rings 33 are respectively mounted on one end of the guide rod 32 via connectors. Multiple second scrapers 34 are respectively mounted on the opposite sides of the multiple mounting rings 33 and are respectively attached to the upper surface of the frustum 21. Two limiting plates 35 are respectively mounted on the guide rod 32 and are respectively attached to the top and bottom of the multiple mounting rings 33.

[0029] The separation device 5 includes: a separation box 51, a filter plate 52, and a cleaning structure 53.

[0030] The separation box 51 has openings 511 on opposite sides, the filter plate 52 is placed on the two openings 511, the cleaning structure 53 is set on the separation box 51, and the cleaning end of the cleaning structure 53 is located on the upper surface of the filter plate 52.

[0031] It should be noted that the top and one side of the separation tank 51 are respectively provided with an inlet and an outlet, and the filter plate 52 is located between the inlet and the outlet. The two ends of the discharge pipe 4 are connected to the reaction tank 2 and the inlet, respectively. The inlet of the return water pump 6 is connected to the outlet through a connecting pipe, which facilitates the filtration of residues in the sewage.

[0032] It should be noted that sliding holes 512 are also provided on both sides of the top of the separation box 51 to facilitate the limiting of the sliding rod 535.

[0033] The cleaning structure 53 includes: a mounting plate 531, a first drive motor 532, a bidirectional lead screw 533, a slider 534, a slide bar 535, a baffle 536, a telescopic rod 537, a first scraper 538, and a spring 539.

[0034] Two mounting plates 531 are respectively set on the top of the separation box 51 and located on opposite sides of the two sliding holes 512. Two first drive motors 532 are respectively set on one side of one of the mounting plates 531 through mounting brackets. Two bidirectional lead screws 533 are respectively axially connected to opposite sides of the two mounting plates 531, and one end of each bidirectional lead screw 533 passes through the mounting plate 531 and is respectively connected to the drive end of the two first drive motors 532. Two sliders 534, two slide rods 535, two baffles 536, two telescopic rods 537 and a first scraper 538 are connected sequentially from top to bottom. The two sliders 534 are respectively set on the two bidirectional lead screws 533. The two slide rods 535 are respectively located in the two sliding holes 512.

[0035] Preferably, the sliding hole 512 is a square hole, and the corresponding sliding rod 535 is a square rod, which facilitates the limiting of the sliding rod 535 through the sliding hole 512, thereby increasing the stability of the slider 534.

[0036] It should be noted that the diameter of the baffle 536 is larger than the width of the sliding hole 512, and it fits into the inner top of the separation box 51, effectively increasing the stability of the slider 534.

[0037] Specifically, when this utility model is used, firstly, by turning on the second drive motor 31, multiple second scrapers 34 are rotated, thereby guiding the reaction residue on the frustum 21 into the discharge pipe 4, and then falling onto the filter plate 52. At the same time, the sewage passes through the filter plate 52, and the residue in the sewage remains on the filter plate 52. Secondly, by turning on the two first drive motors 532, the first scrapers 538 are moved on the upper surface of the filter plate 52, thereby pushing the residue on the filter plate 52 and causing it to fall from the two openings 511. Finally, by turning on the return water pump 6, the sewage inside the separation tank 51 is pumped into the reaction tank 2, thereby achieving the effect of a cyclic reaction.

[0038] It should be noted that before using this utility model, two storage baskets should be prepared on both sides of the opening 511 to catch any residue that falls from the opening 511.

[0039] In summary, the integrated circulating Fenton fluidized bed according to the present invention can filter the residue in the sewage by setting the filter plate 52, and the residue on the filter plate 52 can be easily removed by the cleaning structure 53. This eliminates the need for workers to constantly remove the filter plate 52, thereby effectively improving work efficiency. It is also simple to operate and highly practical.
