[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Example

[0037] like Figure 1-Figure 9 As shown, a device for treating pollutants in organic sulfuric acid waste liquid proposed in Example 1 of the present application includes:

[0038] A waste liquid tank 1, wherein a treatment box 2 is installed on the top of the waste liquid tank 1, and a plurality of stepped drainage plates 3 are installed in a horizontal array in the treatment box 2, and the tops of the plurality of stepped drainage plates 3 cooperate with the treatment box 2 to form a plurality of stepped drainage chambers 4, and the plurality of stepped drainage plates 3, except for the stepped drainage plate 3 located at the bottom, are provided with placement grooves 37 on their upper surfaces, and a plurality of placement openings 5 ​​connected to the placement grooves 37 are provided on one side of the treatment box 2, and also include a plurality of lime bars 6, and the lime bars 6 are inserted into the placement grooves 37 through the placement openings 5, and specifically, one end of the lime bar 6 is located outside, and when the lime bar 6 is used up, it is convenient to add the lime bar 6 from the outside of the treatment box 2 to the placement groove 37, and when the lime bar 6 is inserted into the placement groove 37, the top of the lime bar 6 is flush with the upper surface of the stepped drainage plate 3;

[0039] The diversion mechanism comprises a liquid inlet frame 7 installed on the top of the treatment box 2, a plurality of guide frame plates 8 are installed in a horizontal array inside the treatment box 2, the bottoms of the plurality of guide frame plates 8 are respectively connected to the plurality of stepped drainage chambers 4, and the guide frame plates 8 are located above the stepped drainage plates 3, a connecting pipe 9 is connected between the bottom of the liquid inlet frame 7 and the guide frame plates 8, and an exhaust groove 10 is provided on one side of the treatment box 2, that is, when in use, organic sulfuric acid waste liquid is poured into the liquid inlet frame 7, because the organic acid waste liquid will generate a large amount of heat when it is neutralized with the lime strips 6, so the organic sulfuric acid waste liquid can also be transported to the liquid inlet frame 7 through the pump body and the pipeline, and then the organic sulfuric acid waste liquid will pass through the plurality of connecting pipes 9 into the plurality of guide frame plates 8 to achieve diversion, because the bottom of the guide frame plate 8 is in a connected state with the top of the stepped drainage chamber 4, so the organic sulfuric acid waste liquid is discharged under the action of gravity It will flow out from the bottom of the corresponding stepped drainage chamber 4 along the stepped surface of the stepped drainage plate 3. During this process, the organic sulfuric acid waste liquid will pass through the multiple placement grooves 37 of the stepped drainage plate 3. Because there are lime strips 6 in the placement grooves 37, the organic sulfuric acid waste liquid will react when passing through the lime strips 6, thereby generating calcium sulfate, and the organic sulfuric acid waste liquid will be diverted and contact with the multiple lime strips 6 during the flow process, thereby performing multiple neutralization reactions, thereby achieving neutralization treatment of the organic sulfuric acid waste liquid. The treated organic sulfuric acid waste liquid will finally flow from the stepped drainage chamber 4 into the waste liquid tank 1, and the organic sulfuric acid waste liquid will be further treated subsequently. This neutralization treatment method not only does not require the control of the amount of quicklime, but also can achieve multiple neutralization of the organic sulfuric acid waste liquid by trickling, thereby improving the treatment efficiency of the organic sulfuric acid waste liquid, and making the neutralization treatment more convenient;

[0040] The stirring rod 11 is vertically rotatably installed in the waste liquid tank 1. When the organic sulfuric acid waste liquid after neutralization treatment is located in the waste liquid tank 1, other neutralizing agents can be added from the waste liquid tank 1 to further treat the organic matter and heavy metals in the organic sulfuric acid waste liquid. A motor is installed in the waste liquid tank 1 to drive the stirring rod 11 to rotate, and the organic sulfuric acid waste liquid is located below the motor when in use. Preferably, the bottom of the processing box 2 is located in the waste liquid tank 1 and a baffle is obliquely installed to prevent the organic sulfuric acid waste liquid from falling onto the motor when passing through the stepped drainage cavity 4. Example

[0041] like Figure 1 and Figure 6As shown, this embodiment further improves the present application on the basis of the second embodiment, and multiple stepped drain plates 3 are obliquely distributed along their width, and the highest point of the placement groove 37 is connected to the corresponding placement port 5 and is consistent with the inclination direction of the stepped drain plate 3, so that when the organic sulfuric acid waste liquid flows into the stepped drain plate 3, it will move along the inclination direction of the stepped drain plate 3, which indirectly improves the effect of the neutralization reaction. Moreover, the inclined design of the stepped drain plate 3 makes the lime strip 6 exposed to the outside fill the placement groove 37 due to the direction of gravity when it shortens or breaks after the neutralization reaction, thereby reducing the number of times the staff replenishes the lime strip 6, and the inclined design can effectively prevent the organic sulfuric acid waste liquid inside the treatment box 2 from flowing toward the placement port 5, thereby preventing leakage. Example

[0042] like Figure 2 and Figure 8 As shown, this embodiment further improves the present application on the basis of the second embodiment, and the plurality of the stepped drainage plates 3, except for the stepped drainage plate 3 located at the bottom, are provided with a receiving groove 12 on their upper surfaces, and the stepped drainage plates 3 are provided with a plurality of filter grooves 13 connected with the receiving groove 12 on their vertical surfaces, and the treatment box 2 is provided with a plurality of discharge ports 14 obliquely, and the plurality of discharge ports 14 are respectively connected with the lowest points of the plurality of receiving grooves 12 in the length direction, and an adjustment plate 15 is horizontally slidably installed on the outer side of the treatment box 2, and a plurality of shielding blocks 16 for blocking the discharge ports 14 are constructed on one side of the adjustment plate 15, that is, when the organic sulfuric acid waste liquid flows on the stepped drainage plate 3, the calcium sulfate formed by the neutralization reaction with the lime strip 6 will be located On the surface of the lime bar 6, because the lime bar 6 is inclined at this time and because the organic sulfuric acid waste liquid is in a flowing state, the flowing organic sulfuric acid waste liquid will drive the calcium sulfate and enter the receiving tank 12, and the calcium sulfate located in the receiving tank 12 will continue to flow through the filter tank 13, and because the receiving tank 12 is also in an inclined state, the calcium sulfate will be concentrated at the lowest end of the receiving tank 12. After all the organic sulfuric acid waste liquid in the stepped drainage chamber 4 flows out, the blocking block 16 no longer blocks the discharge port 14 by moving the adjusting plate 15, and the calcium sulfate will roll out from the discharge port 14. Preferably, a box body can be placed on the top of the waste liquid tank 1 to receive the calcium sulfate. In this embodiment, an electric push rod can be used to drive the adjusting plate 15 to move. Example

[0043] like Figure 1 and Figure 2As shown, this embodiment further improves the present application on the basis of the third embodiment, the treatment box 2 is vertically slidably inserted on the top of the waste liquid tank 1, a return spring 17 is installed between the treatment box 2 and the waste liquid tank 1, and a linkage assembly 18 acting on the stirring rod 11 and the treatment box 2 is installed on the waste liquid tank 1. When the stirring rod 11 rotates, the treatment box 2 is driven to reciprocate through the linkage assembly 18. In other words, when the organic sulfuric acid waste liquid after the acid-base neutralization treatment needs to be further neutralized, the rotation of the stirring rod 11 through the linkage assembly 18 will drive the treatment to reciprocate vertically, and the inclined design of the containing tank 12 makes it easier for the calcium sulfate located in the containing tank 12 to be discharged from the discharge port 14.

[0044] like Figure 1 and Figure 5 As shown, in the fourth embodiment, the linkage assembly 18 includes a movable frame 1801 vertically slidably inserted on the top of the waste liquid tank 1, and a movable block 1802 is horizontally slidably installed in the waste liquid tank 1, and a first hinged rod 1803 is hinged between the movable block 1802 and the movable frame 1801, and a second hinged rod 1804 is hinged on the movable block 1802, and a convex plate 1805 is constructed on the stirring rod 11, and the free end of the second hinged rod 1804 is eccentrically hinged on the convex plate 1805, and the movable frame 1801 is detachably connected to the adjusting plate 15, that is, when the stirring rod 11 rotates, the convex plate 1805 will be driven to rotate, because the upper eccentric hinged second hinged rod 1804, and the second hinged rod 1804 and the movable frame 1801 are detachably connected. Block 1802 is hinged, so the rotation of the convex plate 1805 will indirectly drive the moving block 1802 to move back and forth horizontally through the second hinge rod 1804. Because the moving block 1802 is connected to the moving frame 1801 through the first hinge rod 1803, the moving block 1802 will drive the moving frame 1801 to move back and forth vertically through the first hinge rod 1803 when moving back and forth horizontally. Because the moving frame 1801 is connected to the adjustment plate 15, the vertical reciprocating movement of the adjustment plate 15 is realized. The vertical reciprocating movement of the adjustment plate 15 will also drive the processing box 2 to move back and forth vertically, so that the reciprocating movement of the processing box 2 can be realized without additional driving force. When organic sulfuric acid waste liquid is poured into the processing box 2, the moving frame 1801 is not connected to the adjustment plate 15 at this time.

[0045] like Figure 1 , Figure 2 and Fig. 9As shown, in the fourth embodiment, the processing box 2 is horizontally rotatably mounted with an adjusting screw 33, the adjusting plate 15 is threadedly sleeved on the adjusting screw 33, the adjusting plate 15 is horizontally slidably mounted with a moving plate 38, one side of the moving plate 38 is mounted with a snap-on rack 34, the moving frame 1801 is vertically mounted with a docking rack 19 for docking with the snap-on rack 34, a connecting spring 20 is installed between the moving plate 38 and the adjusting plate 15, and when the calcium sulfate in the receiving groove 12 needs to be taken out, the adjusting screw 33 can be rotated at this time. To drive the adjustment plate 15 to move away from the processing box 2. During this process, the moving plate 38 will also move so that the engaging rack 34 is engaged with the docking rack 19. If the engaging rack 34 and the docking rack 19 are misaligned and not engaged, the connecting spring 20 will be in a compressed state. Then, when the moving frame 1801 moves vertically back and forth, the connecting spring 20 will be reset due to its own elastic deformation, so that when the engaging rack 34 and the docking rack 19 are in an engaged state, the engaging rack 34 is engaged with the docking rack 19 through the connecting spring 20. Example

[0046] like Figure 2 and Figure 5 As shown, this embodiment further improves the present application on the basis of the first to fourth embodiments, a mounting box 21 is installed on one side of the waste liquid tank 1, a storage box 22 is installed on the top of the mounting box 21, the bottom surface of the storage box 22 is an inclined surface, and a connecting frame 23 is connected between the lowest end and the top of the mounting box 21, a hollow rod 24 is installed horizontally and rotatably inside the mounting box 21, a stirring impeller 25 is installed on the outer peripheral side of the hollow rod 24, and a device for conveying hot air to the inside of the hollow rod 24 is installed on the waste liquid tank 1. That is to say, when the processing box 2 is shaken, the calcium sulfide will be shaken into the storage box 22. At this time, the calcium sulfide will have a certain amount of moisture. The calcium sulfide in the storage box 22 will be pushed into the installation box 21, and then the hollow rod 24 is heated by the transmission component 26. The installation box 21 is equipped with a motor for driving the hollow rod 24 to rotate. The increase in the temperature of the hollow rod 24 indirectly increases the temperature of the stirring impeller 25, thereby heating the calcium sulfate in the installation box 21 and accelerating the evaporation of moisture on the surface of the calcium sulfate.

[0047] like Figure 1As shown, in Example 5, the transmission component 26 includes an air pump 2601 installed on the waste liquid tank 1, a first pipe 2602 is connected between one end of the air pump 2601 and one end of the hollow rod 24 via a rotating joint, a second pipe 2603 is connected between one end of the air pump 2601 and the other end of the hollow rod 24 via a rotating joint, and a heating component 2604 for heating the first pipe 2602 is installed on the waste liquid tank 1. Specifically, the heating component 2604 can be an existing electric heating wire heater or a steam heater. Different heating methods can be selected according to different usage environments to heat the air in the second pipe 2603. Specifically, the first pipe 2602 and the second pipe 2603 are both flexible pipes, and sufficient space is left for the processing box 2 to shake back and forth vertically. Example

[0048] like Figure 1 and Figure 3 As shown, this embodiment further improves the present application on the basis of embodiments one to five, a connecting frame 31 is installed on the processing box 2, a plurality of mounting tubes 32 are installed on one side of the connecting frame 31, a push rod 27 is slidably inserted at one end of the mounting tube 32, the free ends of the plurality of push rods 27 are all in contact with one end of the plurality of lime bars 6, and the plurality of mounting tubes 32 are connected in sequence through pipelines, and the second pipeline 2603 includes a connecting pipe 28 installed on the air pump 2601, the connecting pipe 28 is connected to the first mounting tube 32, the mounting tube 32 at the tail is connected to the mounting pipe 35, a three-way control valve 29 is installed on the mounting pipe 35, an exhaust pipe 36 is installed on one mounting end of the three-way control valve 29, a butt joint 30 is installed on the other mounting end of the three-way control valve 29, one end of the butt joint 30 is connected to one end of the hollow rod 24 through a rotating joint, and when the hollow rod 24 is heated, the mounting pipe 35 and the butt joint 30 are kept in contact through the three-way control valve 29. The exhaust pipe 36 remains connected and the exhaust pipe 36 remains blocked. Because the second pipe 2603 and the first pipe 2602 are in a flowing state at this time, when the gas flows into the installation cylinder 32, the flowing gas will push the push rod 27, so that one end of the push rod 27 is always in contact with one end of the lime bar 6, so that there is no need to manually push the lime bar 6 into the placement groove 37, and it is ensured that there is always a lime bar 6 in the placement groove 37. When the lime bar 6 is used up and it is necessary to replace the lime bar 6, the three-way control valve 29 can be controlled at this time to keep the exhaust pipe 36 connected to the docking pipe 30, and the connection between the installation pipe 35 and the three-way valve control valve remains blocked. In this way, when the air pump 2601 is started, the air inside the installation cylinder 32 can be extracted and finally discharged from the exhaust pipe 36. At this time, because a negative pressure is formed inside the installation cylinder 32, the push rod 27 is driven to move into the corresponding installation cylinder 32, thereby realizing the simultaneous retraction of multiple push rods 27, which is convenient for the subsequent addition of lime bars 6 to the placement groove 37.

[0049] The present application also proposes a process for treating pollutants in organic sulfuric acid waste liquid, which is applied to the above-mentioned equipment for treating pollutants in organic sulfuric acid waste liquid, and comprises the following steps:

[0050] S1: pouring the organic sulfuric acid waste liquid into the liquid inlet frame 7, so that the organic sulfuric acid waste liquid flows into the stepped drainage cavity 4, so that the organic sulfuric acid waste liquid contacts with a plurality of guide frame plates 8;

[0052] S3: using the linkage assembly 18 to realize the reciprocating movement of the processing box 2, and moving the adjustment plate 15 so that the discharge port 14 is no longer blocked by the blocking block 16, thereby shaking the calcium sulfate into the installation box 21;
