Description

Technical Field

[0001] The invention relates to the technical field of wastewater electrolysis treatment, in particular to a accelerator wastewater electrolysis treatment device with continuous separation and purification functions. Background Art

[0002] The chemical name of the vulcanization accelerator CBS is N-cyclohexyl-2-benzothiazole sulfonamide, which is a commonly used after-effect rubber vulcanization accelerator and one of the environmentally friendly accelerators currently used at home and abroad. Among its synthesis methods, the sodium hypochlorite oxidation method is an important method for industrial synthesis. It mainly uses the oxidant sodium hypochlorite to oxidize the raw materials MBT and cyclohexylamine to synthesize CBS and generate sodium chloride. After the synthesis, a large amount of high-salt wastewater will be generated. In addition to about 12% of sodium chloride, the wastewater also contains organic cyclohexylamine, accelerator M, and accelerator CBS. Therefore, the wastewater must be treated before it can be discharged.

[0003] Patent CN112573624B discloses a composite catalytic oxidation treatment system for high-salt wastewater, which discharges high-salt wastewater into an electrolytic cell and uses OH free radicals generated by electrolysis in combination with ultraviolet light to catalytically oxidize organic matter to achieve the purpose of reducing the COD of the wastewater. However, when treating the promoter CBS wastewater, the treatment system will re-oxidize the cyclohexylamine and promoter M in it to synthesize the product CBS. Since the system does not have a CBS recovery function, a large amount of product is wasted.

[0004] Patent CN112551773A discloses a process and device for resource treatment of wastewater produced by rubber accelerator NS. The process pre-treats the wastewater by passing it through a macroporous resin adsorption unit before the electrolytic catalytic unit, adsorbs most of the tert-butylamine, accelerator M and accelerator NS in the wastewater into the resin, and then passes the resin effluent into an electrolytic catalytic oxidation unit for deep treatment, thereby achieving the purpose of recovering the accelerator product in advance. However, the accelerator of this process cannot be directly recovered, and the adsorbed macroporous resin must be desorbed before it can be recovered, which increases the cost of recycling and treatment.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, a accelerator wastewater electrolysis treatment device with continuous separation and purification function includes a first electrolytic box 1, a second electrolytic box 2, a connecting pipe 3, an ultrasonic vibrator 6, an anode 4, and a cathode 8. The first electrolytic box 1 and the second electrolytic box 2 are vertical rectangular parallelepiped structures. The anode 4 and the ultrasonic vibrator 6 are both located in the first electrolytic box 1, and the cathode 8 is located in the second electrolytic box 2. A chlorine gas discharge pipe 7 is installed on the upper part of the first electrolytic box 1, and a waste liquid inlet 5 is installed on the lower part of the first electrolytic box 1. A hydrogen discharge pipe 10 is installed at the upper part of the electrolytic box 2, a waste liquid outlet 9 is installed at the lower part of the second electrolytic box 2, a connecting pipe 3 is used to connect the electrolyte, the liquid inlet end of the connecting pipe 3 is connected to the upper part of the first electrolytic box 1, and the liquid outlet end of the connecting pipe 3 is connected to the lower part of the second electrolytic box 2. The waste liquid to be treated enters the first electrolytic box 1 through the waste liquid inlet 5 in turn, and the chloride ions in the waste liquid are electrolytically oxidized in the first electrolytic box 1 to generate chlorine gas. During the floating process of the chlorine gas, it reacts with OH in the waste liquid under the action of the ultrasonic vibrator 6. - The ions react to generate hypochlorite ions, which oxidize cyclohexylamine and MBT to form water-insoluble organic matter CBS. The unreacted chlorine is discharged through the chlorine discharge pipe 7. CBS is suspended under the action of the ultrasonic vibrator 6 and is difficult to precipitate in the first electrolytic box 1. In addition, when the waste liquid to be treated continues to pass through the waste liquid inlet 5, CBS will enter the second electrolytic box 2 together with the waste liquid that has been electrolyzed through the connecting pipe 3. The H in the second electrolytic box 2 + Hydrogen is generated under the action of the cathode 8, and the waste liquid is finally discharged through the waste liquid outlet 9. The waste liquid to be treated flows continuously in a serpentine shape inside the first electrolytic box 1, the connecting pipe 3, and the second electrolytic box 2.

[0026] CBS is difficult to precipitate and collect, and an extraction mechanism needs to be installed for filtration and separation. The extraction mechanism is installed on the connecting pipe 3, such as Figure 1 and Figure 2As shown, the extraction mechanism includes a guide pipe 11, a conical filter 12, a first spiral plate 13, a bell-shaped connecting pipe 14, a connecting rod 15, an impeller 16, a second spiral plate 18, and a sealing ring 19. The guide pipe 11 is a tubular structure with one end larger than the other end. Both ends of the guide pipe 11 are fixedly connected to the connecting pipe 3 through flanges. The guide pipe 11 divides the connecting pipe 3 into two sections, and the guide pipe 11 is fixedly connected between the two sections of the connecting pipe 3. The conical filter 12 is intercepted in the guide pipe 11 in a transverse section. The edge of the filter 12 is fixed to the flange by screws. The first spiral plate 13 is arranged around the conical filter 12 and is rotatably connected to the filter 12. The first spiral plate 13 The outer spiral edge is connected to the inner surface of the connecting pipe 14, and the connecting pipe 14 is half-covered on the large end of the filter screen 12. The second spiral plate 18 is coiled and fixed on the outer surface of the small end of the connecting pipe 14. The spiral direction of the second spiral plate 18 is opposite to that of the first spiral plate 13. The sealing ring 19 is sleeved and fixedly connected to the large end of the connecting pipe 14. The sealing ring 19 is fixedly sleeved on the outer periphery of the connecting pipe 14 and the sealing ring 19 is in circumferential sealing contact with the port of the guide pipe 11. The sealing ring 19 seals the gap between the connecting pipe 14 and the guide pipe 11. The sealing ring 19 is rotatably connected to the guide pipe 11. The filter screen 12, the first spiral plate 13, the connecting pipe 14, and the second spiral plate 18 are nested in sequence and are connected together. The impeller 16 is located inside one end of the guide tube 11, and the outer edge of the small end of the connecting tube 14 is provided with a plurality of connecting rods 15. The impeller 16 is located inside the other end of the guide tube 11, and the impeller 16 is fixedly connected to the outer edge of the connecting tube 14 through the connecting rod 15. The guide tube 11, the first spiral plate 13, the filter screen 12, the connecting tube 14, and the sealing ring 19 together form a push cavity. The discharge pipe 17 is installed on the guide tube 11, and the discharge pipe 17 is vertically upward and communicated with the push cavity. The impeller 16 rotates under the impetus of the liquid, and drives the first spiral plate 13 and the second spiral plate 18 to rotate. Here, the impeller 16 is driven to rotate by water flow. This structure is similar to the structure of rotating the blades of a fan by blowing wind. The invention is based on the prior art, and the first spiral plate 13 and the second spiral plate 18 are driven to spirally rotate by the connecting rod 15. The first spiral plate 13 collects and transports the solids accumulated on the filter screen 12 to the pushing cavity by means of spiral rotation forced discharge. The second spiral plate 18 discharges the solids gathered between the guide pipe 11 and the connecting pipe 14 and acts as a friction barrier. The water flow rotates under the reverse action of the impeller 16. The rotating wastewater impacts the center of the filter screen 12, and the solids adhered to the filter screen 12 are peeled off, so that the solids are accelerated to roll on the surface of the conical filter screen 12, thereby avoiding the problem of large amount of material accumulation, accelerating the filtration speed, and improving the feeding capacity of the first spiral plate 13.

[0027] Under the rotation and push of the first spiral plate 13, the solid is transmitted upward from the pushing cavity through the discharge pipe 17. The filtrate passes through the conical filter screen 12 under the action of gravity and then flows back to the guide pipe 11, so as to realize the pressure filtration separation of the solid and the waste liquid. However, the upward pushing capacity of the first spiral plate 13 is limited and cannot be transported over a long distance. An external material transfer mechanism is required to discharge the solid in time. The material transfer mechanism includes a lifting pipe 20 and a first power mechanism. The lifting pipe 20 is installed on one side of the guide pipe 11. The lifting pipe 20 is vertically arranged. A discharge port 30 is provided at the upper part of the circumferential surface of the lifting pipe 20, and a feed port 25 is provided at the lower part of the circumferential surface of the lifting pipe 20. The discharge pipe 17 is connected to the feed port 25 after being bent horizontally. A lifting block 26 is installed in the lifting pipe 20. The lifting block 2 The upper surface of 6 forms an inclined surface that is easy to discharge, and the inclined surface is set toward the discharge port 30. A plurality of filter holes can be opened on the lifting block 26 to further separate the waste liquid. The first power mechanism can be a cylinder, which is vertically installed on the top of the lifting pipe 20 downward. The output end of the cylinder is fixedly connected to the lifting block 26. The cylinder drives the lifting block 26 to slide from the bottom of the feed port 25 to the discharge port 30. The solid passes through the pushing cavity and enters the discharge pipe 17, and then enters the upper inclined surface of the lifting block 26 through the feed port 25. The lifting block 26 moves to the discharge port 30 driven by the cylinder, and the solid accumulated on the inclined surface of the lifting block 26 slides to the discharge port 30 under the action of gravity. The lifting block 26 reciprocates up and down to continuously discharge the solid.

[0028] During the up and down movement of the cylinder, a small amount of solids may fall below the lifting block 26. The lower part of the lifting pipe 20 extends downward to form a temporary storage bin, which can store the solids in time to avoid hindering the normal operation of the lifting block 26. Personnel can regularly clean the solids in the temporary storage bin to ensure long-term operation of the equipment.

[0029] In some embodiments, the first power mechanism may be driven by a cylinder in addition to other driving forms. The first power mechanism includes a thin tube 21, a thick tube 22, a first sliding plug 28, a second sliding plug 29, and a pull rope 27. One end of the thin tube 21 is horizontally welded to the end of the thick tube 22, and the other end of the thin tube 21 is horizontally welded to the upper part of the lifting tube 20. The first sliding plug 28 and the second sliding plug 29 are both made of resin. The first sliding plug 28 slides left and right in the thin tube 21. The first sliding plug 28 is a cylinder, and the second sliding plug 29 slides left and right in the thick tube 22. The second sliding plug 29 is also a cylinder, and the cross section of the left end thereof is a trapezoid, so that the second sliding plug 29 and the thick tube 22 form an air inlet chamber. The thick tube 22 is provided with an air inlet 23 and an air outlet 24. The air inlet 23 and the air outlet 24 are respectively located at the ends of the thick tube 22. The air inlet 23 is located at the left end of the thick tube 22, and the air outlet 24 is located at the right end of the thick tube 24. One end of the pull rope 27 is fixedly connected to the lifting The lifting block 26 and the other end of the pull rope 27 are connected to the first sliding plug 28 and the second sliding plug 29 in sequence. The air inlet 23 is connected to the first electrolytic box 1 through the chlorine gas discharge pipe 7. The weight of the lifting block 26 is greater than the total weight of the first sliding plug 28, the second sliding plug 29 and the pull rope 27, so that the lifting block 26 slides down to the bottom of the feed port 25 in a natural state. Chlorine enters the air inlet chamber through the chlorine gas discharge pipe 7. Under the continuous electrolysis of the first electrolytic box 7, the internal pressure increases and pushes the second sliding plug 29 to move rightward. The second sliding plug 29 drives the first sliding plug 28 to move rightward and drives the lifting block 26 to move upward until the second sliding plug 29 passes over the air outlet 24 for discharge. The lifting block 26 moves to the discharge port 30 to complete the discharge. After the pressure relief is completed, the lifting block 26 droops again to the bottom of the feed port 25 to realize a reciprocating cycle. When the pressure in the first electrolytic box 1 slowly increases, the solubility of chlorine in the waste liquid will also increase, and finally the oxidation synthesis efficiency of organic matter in the waste liquid will be improved.

[0030] The pull rope 27 can take many forms. Here, a flat long belt structure is selected to prevent the inclined surface of the upper part of the lifting block 26 from shifting due to rotation during the movement of the lifting block 26. Similarly, the pull rope 27 can take a thin rope structure. At this time, a limiting structure can be added between the lifting block 26 and the lifting tube 20 to ensure that the position of the lifting block 26 is not shifted.

[0031] Example 2

[0032] like Figure 4 , Figure 5As shown, on the basis of Example 1, a backwashing mechanism is added, and also includes a liquid transfer box 33, a liquid transfer pipe 34, and a second power mechanism. The liquid transfer pipe 34 is U-shaped and is located in the liquid transfer box 33. The extraction mechanism, the material transfer mechanism, and the first power mechanism are replaced by being installed on the connecting pipe 3 instead of being installed on the liquid transfer pipe 34. The connecting pipe 3 connects the liquid transfer box 33 and the second electrolytic box 2. The first liquid outlet pipe 31 and the second liquid outlet pipe 32 are installed on the first electrolytic box 1. The first liquid outlet pipe 31 and the second liquid outlet pipe 32 are arranged up and down. The first liquid outlet pipe 31 and the second liquid outlet pipe 32 extend horizontally into the liquid transfer box 33. The liquid transfer pipe 34 is arranged horizontally and transversely. The first interface 35 and the second interface 36 are installed at one end of the liquid transfer pipe 34, and the other end of the liquid transfer pipe 34 is provided with a first interface 35 and a second interface 36. A third interface 37 and a fourth interface 38 are installed at one end, and the first interface 35, the second interface 36, the third interface 37, and the fourth interface 38 are arranged flush with each other from top to bottom. The first interface 35, the second interface 36, the third interface 37, and the fourth interface 38 are arranged in sequence from top to bottom. The first interface 35 and the fourth interface 38 are aligned with the first liquid outlet pipe 31 and the second liquid outlet pipe 32 respectively. A conversion plate 39 is installed in the gap between the first interface 35, the second interface 36, the third interface 37, and the fourth interface 38 and the first liquid outlet pipe 31 and the second liquid outlet pipe 32. The conversion plate 39 is a flat plate structure, and the conversion plate 39 is provided with a first liquid hole 40, a second liquid hole 41, and a third liquid hole 42 at intervals. The first liquid hole 40 and the second liquid hole 41 are arranged at intervals. The diameter of the third liquid hole 42 is equal to the diameter of the first interface 35, the second interface 36, the third interface 37, and the fourth interface 38. The thickness of the conversion plate 39 is equal to the gap between the first interface 35 and the first liquid outlet pipe 31, and the gap between the fourth interface 38 and the second liquid outlet pipe 32, so that the conversion plate 39 is just stuck between the first liquid outlet pipe 31, the second liquid outlet pipe 32 and the first interface 35, the second interface 36, the third interface 37, and the fourth interface 38. The second power mechanism can be driven by a cylinder, and the output end of the cylinder is fixedly connected to the upper end of the conversion plate 39. The cylinder drives the conversion plate 39 to move up and down to realize the gap between the first interface 35 and the first liquid outlet pipe 31, the gap between the fourth interface 38 and the second liquid outlet pipe 32, the second interface 36, and the third interface 37. The first interface 35 is blocked or connected with the first liquid outlet pipe 31, the second interface 36 is blocked, the third interface 37 is opened for liquid, the fourth interface 38 is blocked with the second liquid outlet pipe 32, the waste liquid enters from the first interface 35 and exits from the third interface 37, the conversion plate 39 moves, when the fourth interface 38 is opened and connected with the second liquid outlet pipe 32, the first interface 35 is blocked with the first liquid outlet pipe 31, the second interface 36 is opened, the third interface 37 is blocked, the waste liquid enters from the fourth interface 38 and exits from the second interface 36, and the position of the conversion plate 39 is changed, so as to change the flow direction of the waste liquid in the transfer pipe 34 and realize the flushing and cleaning of the extraction mechanism. Compared with the valve-controlled flow direction flushing, it is not only more convenient to operate, but also can avoid the problem of valve clogging by solids.

[0033] In addition to using a cylinder to drive the conversion plate 39 to move, the second power mechanism can also use other methods, such as an adjusting screw 43 and an adjusting nut 44. The adjusting nut 44 is fixedly connected to the liquid transfer box 33. The adjusting screw 43 passes through the adjusting nut 44 and the top surface of the liquid transfer box 33 in sequence. The adjusting screw 43 and the adjusting nut 44 are threadedly connected. The adjusting screw 43 and the liquid transfer box 33 are rotationally connected. The bottom of the adjusting screw 43 is fixedly connected to the top of the conversion plate 39. The person can adjust the position of the conversion plate 39 by manually rotating the adjusting screw 43 by adjusting the hand wheel.
