Description

Technical Field

[0001] The invention relates to the technical field of chemical reaction treatment, in particular to a reaction kettle for preparing polyaluminium ferric sulfate by recovering tail liquid from waste catalyst. Background Art

[0002] Polyaluminium ferric sulfate is a flocculant, mainly used as a treatment agent for drinking water and industrial water, as well as a treatment agent for industrial wastewater, urban sewage and sludge. It has the functions of decolorization, deodorization, demulsification and sludge dehydration. At present, polyaluminium ferric sulfate is mainly produced in two ways, one is direct oxidation method and the other is catalytic oxidation method. The raw material cost of direct oxidation method is higher than that of catalytic oxidation method, so catalytic oxidation method is mostly used for production. By stirring in the reactor, low molecular weight compounds (polymerize into high molecular weight compounds through chemical reaction. Specifically, ferrous sulfate (FeSO4) and aluminum sulfate tail liquid (H2SO4) react in the reactor to generate polyaluminium ferric sulfate.

[0003] Related technology 1 (publication number: CN105214592A) discloses a reaction device for producing polyferric sulfate, and the disclosed technical solution is as follows: a porous sieve plate unit and an aeration unit are added to a traditional reactor, the porous sieve plate unit increases the suspension time of the liquid through the filling body, and oxygen is released from the aeration unit and diffused throughout the reactor, thereby increasing the contact area and contact time of gas and liquid, and improving the reaction rate and production efficiency; Related technology 2 (publication number: CN112973602A) discloses a catalytic oxidation reactor for the production of polyferric sulfate, and the disclosed technical solution is as follows: by setting an auxiliary catalytic device, an air pump can be used to input pure oxygen from a rotary joint, and the oxygen enters the aeration mechanism through the oxygen delivery chamber to add oxygen to the solution in the kettle. The addition of oxygen can greatly promote the oxidation reaction and save the amount of catalyst. By rotating the rotating shaft, while stirring the solution in the kettle, the position of oxygen injection is constantly changed, so that the oxygen and solution in the kettle are mixed evenly and fully, thereby improving the production efficiency of polyaluminium ferric sulfate; by setting a heating mechanism, when the rotating shaft rotates, the heating mechanism also keeps changing its position, so that the temperature of the solution in the kettle rises more evenly, promoting the oxidation reaction; by setting a secondary shaft and blades, when the blades rotate with the secondary shaft, a downward thrust is generated on the solution, so that the solution in the kettle is constantly turned over, and when the aeration device injects oxygen into the solution, the oxygen bubbles will extend the residence time in the solution under the action of the blades, and at the same time, the oxygen and solution are fully mixed, thereby promoting the oxidation reaction; Related technology 3 (publication number: CN215028908U) discloses a reaction kettle of ferric sulfate, and the disclosed technical solution is: a first motor, a first rotating rod, a first gear, a second gear, a second rotating rod, a dispersion disk and a stirring rod are arranged, and the first motor drives the dispersion disk and the stirring rod to rotate at the same time in coordination with the mutual meshing of the first gear and the second gear, so as to achieve the effect of breaking up and stirring the materials, thereby improving the reaction efficiency; Related technology 4 (publication number: CN114588864A) discloses an anti-blocking reactor for producing polyferric sulfate, and the disclosed technical solution is: in order to ensure the reaction rate and post-treatment during the production of polyferric sulfate, the concentration of the reaction liquid is high, and crystallization or impurity blockage is prone to occur during the production process. Once crystallization occurs, it is difficult to dissolve and dredge with the reaction liquid, and friction dredging is more suitable. Friction dredging requires stopping the reaction, which will affect the processing progress. The present invention adopts the combination of a float, an umbrella-shaped part, and a poking needle. When the reaction circulation system is blocked, the flow rate is changed to make the liquid outlet hole conductive, which does not affect the reaction and does not need to be disassembled for maintenance; In the above disclosed technical solution, the following problems are found in the related technology: in the process of preparing polyferric sulfate, a mixing reaction is carried out by setting a stirrer to obtain polyferric sulfate, but in this process, the blades of the stirrer may cause corrosion of the stirring shaft and the blades due to the quality of the material, and the halogen elements in the system exceed the material selection requirements, resulting in severe wear; Furthermore, in situations where the stirring is vigorous, the viscosity of the liquid kettle reactor is low, or the average residence time is long, there may be problems with the flow pattern of the materials in the kettle, affecting the mixing effect; Therefore, we proposed a new reactor for recovering tail liquid from waste catalyst to prepare polyaluminium ferric sulfate.

One end of the reflux pipe 11 is sealed and connected to the liquid output end of the circulating pump 10, and the other end of the reflux pipe 11 is embedded and installed at the top of the outer wall of the reactor 1, so that the reflux pipe 11 is connected to the inner cavity of the reactor 1. The liquid input end of the circulating pump 10 is sealed and connected to the bottom of the reactor 1 through the liquid inlet pipe.

[0026] By adopting the above structure, the raw materials put into the reactor 1 are circulated through the circulation pump 10. After repeated circulation, the raw materials are mixed and stirred many times, avoiding the built-in stirring components from affecting the reaction quality of the raw materials, thereby improving the quality of polyaluminum ferric sulfate.

[0027] The inner cavity of the reactor 1 is embedded with a conical vortex bin 9. The conical vortex bin 9 is fixedly embedded in the inner cavity of the reactor 1, and the conical vortex bin 9 is located near the bottom of the reactor 1. Eccentric surge holes 14 are symmetrically provided on both sides of the outer wall of the conical vortex bin 9. Eccentric surge holes 14 penetrating the side walls are provided on both sides of the outer wall of the conical vortex bin 9 at positions deviated from the center, and the inner cavity of the conical vortex bin 9 is connected to the inner cavity of the reactor 1 through the eccentric surge holes 14. A reflux funnel 15 arranged in the inner cavity of the reactor 1 is fixedly connected to the bottom of the conical vortex bin 9, and the reflux funnel 15 is connected to the inner cavity of the conical vortex bin 9, and the bottom of the reflux funnel 15 is connected to the liquid inlet of the circulation pump 10.

[0028] The upper outer wall of the reflux bucket 15 is fitted on the inner wall of the reactor 1, so that the reflux bucket 15 is fixed in the inner cavity of the reactor 1. The bottom of the conical vortex bin 9 is an open structure, and the reflux bucket 15 is fixedly installed on the bottom of the conical vortex bin 9. The top of the conical vortex bin 9 is a closed structure, and the bottom periphery of the conical vortex bin 9 is fitted on the inner wall of the reactor 1, so that the liquid in the inner cavity of the reactor 1 enters the inner cavity of the conical vortex bin 9 through the eccentric surge hole 14, enters the circulation pump 10 through the reflux bucket 15 below the conical vortex bin 9, is brought into the inner cavity of the reflux pipe 11 through the circulation pump 10, and returns to the inner cavity of the reactor 1 again through the reflux pipe 11.

[0029] By adopting the above structure, in the process of mixing liquids, when the liquid passes through the eccentric flow holes 14 on both sides, since the eccentric flow holes 14 on both sides are symmetrically located at eccentric positions, the liquid entering the conical vortex chamber 9 on both sides forms a vortex, and the vortex liquid improves the efficiency of liquid circulation, thereby ensuring the effect of stirring the liquid raw materials.

[0030] A heater 16 is provided on the outer wall of the reactor 1. The liquid circulation of the entire system of the heater 16 of the reactor 1 is closed. The system is equipped with an expansion vessel. The expansion vessel and the liquid circulation are insulated and do not participate in the liquid circulation. They are only mechanically connected. Regardless of whether the temperature of the liquid circulation is high or low, the medium in the expansion vessel is lower than 60 degrees. The entire liquid circulation is a closed system. There is no absorption of water vapor at low temperatures, and no oil mist is generated at high temperatures. The heat transfer oil can have a wide working temperature; the same machine and the same heat transfer medium can achieve temperature control from -95 degrees to 200 degrees. The cooling capacity ranges from 1KW to 80KW. No mechanical or electronic valves are used in the entire circulation system. The heater 16 is fixedly embedded and installed on the outer wall of the reactor 1. The heating component of the heater 16 is located in the inner cavity of the reactor 1. The heater 16 provides heat to the reaction process of the polyaluminum ferric sulfate to ensure the production quality of the polyaluminum ferric sulfate.

[0031] With the above structure, the inner cavity of the reactor 1 is provided with a circulation track 3 for extending the flow time of the liquid. The circulation track 3 increases the time of the liquid in the reactor 1, so that the liquid raw material is more fully heated to ensure the mixing effect of the polyaluminum ferric sulfate raw material, thereby improving the quality of the polyaluminum ferric sulfate. The liquid outlet of the circulation track 3 is connected to the eccentric flow hole 14, so that the liquid enters the interior of the eccentric flow hole 14 after passing through the circulation track 3, and then circulates and stirs and mixes through the formed vortex. The circulation track 3 is located above the conical vortex bin 9.

[0032] Among them, a partition chamber 2 is fixedly connected to the top of the reactor 1, and a sealing plate 21 is provided at the joint between the partition chamber 2 and the reactor 1. The partition chamber 2 is fixedly fixed on the top of the reactor 1, so that the reactor 1 is connected to the inner cavity of the partition chamber 2. The sealing plate 21 is fixedly embedded and installed at the joint between the partition chamber 2 and the reactor 1, and the space of the partition chamber 2 and the reactor 1 is divided into two parts by the sealing plate 21. An eight-shaped slide 22 is embedded in the top of the sealing plate 21, and a slide rod 23 is evenly slidably provided in the inner cavity of the eight-shaped slide 22. The eight-shaped slide 22 in the shape of the Arabic numeral "8" is fixedly embedded and installed at the bottom of the sealing plate 21, and passes through the inner cavity, so that the reactor 1 and the partition chamber 2 are connected through the eight-shaped slide 22.

[0033] The bottom end of the slide bar 23 is provided with a disintegrating member 24 extending to the inner cavity of the reactor 1. The slide bar 23 extends to the inner cavity of the reactor 1 after passing through the splayed slideway 22. The disintegrating member 24 is fixedly installed at the end of the slide bar 23 located in the inner cavity of the reactor 1. The inner cavity of the partition chamber 2 is provided with a circulation driving component 4 that drives the slide bar 23 to slide along the splayed slideway 22 in a circulation manner.

[0034] By adopting the above structure, the three slide bars 23 are caused to slide circularly along the figure-eight slideway 22 through the circulating drive component 4, so that the three slide bars 23 drive the dispersing pieces 24 at the bottom to slide circularly along the trajectory of the number "8", so that the liquid raw materials entering the reactor 1 fall on the three circulating sliding dispersing pieces 24, and the liquid raw materials are dispersed by the dispersing pieces 24, and the dispersed liquid raw materials are mixed more evenly with each other, thereby improving the effect of mixing and stirring the raw materials, and further improving the efficiency of the polyaluminum ferric sulfate processing process.

[0035] It is worth noting that the circulating drive assembly 4 includes a turntable 41 that is rotated in the opposite direction and arranged at the top of the inner wall of the partition chamber 2. The circumferential outer wall of the turntable 41 is evenly provided with a card slot 42. The inner cavity of the card slot 42 is carded with a card block 43 fixed to the top of the slide bar 23, and the card block 43 fits the top of the eight-shaped slideway 22. Three card slots 42 are evenly provided on the circumferential outer wall of each turntable 41, and the card block 43 is driven to move by the card slot 42. The card slots 42 at each position on the two turntables 41 are in relative positions. When the two turntables 41 rotate in the opposite direction to the adjacent position, one of the card slots 42 on the two turntables 41 converges. The outer wall of the slide bar 23 is sleeved with a limit card 44 that fits the bottom of the eight-shaped slideway 22. The card block 43 is fixedly installed on the top of the slide bar 23, and the limit card 44 is fixedly sleeved on the outside of the slide bar 23 through the mounting hole opened in the center.

[0036] By adopting the above structure, when the slide rod 23 slides against the inner wall of the shaped-eight slide 22, the slide rod 23 simultaneously drives the limit clamp 44 and the block 43 to slide against the upper and lower surfaces of the shaped-eight slide 22 respectively. The slide rod 23 is limited by the limit clamp 44 and the block 43 during its sliding process to prevent the slide rod 23 from being separated from the shaped-eight slide 22, thereby ensuring the stability of the dispersion treatment of the raw materials after entering the reactor 1.

[0037] The top of the sealing plate 21 is rotatably provided with a lever member 46 for adjusting the direction of the slide bar 23. Since the trajectory of the figure-eight slideway 22 needs to be moved to the corresponding direction at the junction to ensure the "eight" circular sliding. The inner cavity of the partition chamber 2 is provided with a direction-changing component 5 for driving the lever member 46 to swing back and forth, and the inner cavity of the partition chamber 2 is provided with a rotating driving component 6 for driving the two rotating disks 41 to rotate toward each other.

[0038] With the above structure, the lever member 46 is swung back and forth through the direction-changing component 5. When one of the slide bars 23 slides to the adjacent position of the two turntables 41, that is, the slide bar 23 is simultaneously in the slots 42 of the two turntables 41, the direction in which the lever member 46 is moved by the direction-changing component 5 causes the slide bar 23 to slide along the direction corresponding to the figure-eight slideway 22 through the limit of the lever member 46, thereby ensuring that the three slide bars 23 continue to break up the raw materials along the figure-eight slideway 22, thereby ensuring the efficiency of the raw material breaking up and improving the raw material mixing effect.

[0039] In addition, the direction-changing assembly 5 includes a driving shaft 51 rotatably arranged on the sealing plate 21. A mounting bearing is embedded in the top of the sealing plate 21, and one end of the driving shaft 51 is embedded in the mounting bearing, so that the driving shaft 51 rotates on the sealing plate 21.

The driving half gear 52 is sleeved on the outer wall of the driving shaft 51, and the outer wall of the movable shaft 45 where the lever member 46 is located is sleeved on the driven half gear 53. A mounting bearing is embedded in the top of the sealing plate 21, and one end of the movable shaft 45 is embedded and installed inside the bearing. One end of the lever member 46 is fixedly sleeved on the outside of the movable shaft 45 through an opening of a mounting hole. The driven half gear 53 is fixedly sleeved on the outside of the movable shaft 45 through an opening of a mounting hole.

[0040] A transmission rack 54 is provided between the driven half gear 53 and the driving half gear 52 and is slidably provided on the sealing plate 21. The two sides of the transmission rack 54 are respectively meshed with the driven half gear 53 and the driving half gear 52. The transmission rack 54 slides on the sealing plate 21. Teeth are evenly provided on both sides of the transmission rack 54, and the teeth on both sides are respectively meshed with the driven half gear 53 and the driving half gear 52. A guide rail 55 is sleeved on the outer wall of the driving shaft 51, and a slider 56 is slidably provided on the outer wall of the guide rail 55. A driving member 57 is rotatably provided on the inner wall of the partition chamber 2, and the free end of the driving member 57 is rotatably connected to the slider 56.

[0041] The motor is fixed on the inner wall of the compartment 2 through a machine cover, and one end of the active member 57 is fixedly sleeved on the outside of the motor output shaft through the opening of the mounting hole. The other end of the active member 57 is movably sleeved on the outside of the transmission rod 58 through the opening of the mounting hole, and the other end of the transmission rod 58 is vertically fixed on the surface of the slider 56. Guide grooves are provided on both sides of the guide rail 55, and guide blocks are fixedly installed on both sides of the slider 56. The slider 56 is sleeved on the outside of the guide rail 55, and the slider 56 drives the guide block to slide against the inner wall of the guide groove.

[0042] With the above structure, in the process of adjusting the direction of the slide bar 23, the motor is connected to the power supply through the wire, so that the output shaft of the motor drives one end of the active member 57 to rotate continuously, so that the active member 57 drives the slider 56 to slide on the guide rail 55 through the transmission rod 58, so that the guide rail 55 drives the active shaft 51 to swing back and forth after being subjected to force, so that the active half gear 52 swings back and forth with the active shaft 51, and drives the driven half gear 53 to swing back and forth through the transmission rack 54, so that the driven half gear 53 drives the lever member 46 to swing back and forth through the movable shaft 45, and the direction of the slide bar 23 is adjusted by the lever member 46, which ensures that the three slide bars 23 slide in a cycle along the eight-shaped slideway 22, so that the scattering member 24 continuously disperses the raw materials, thereby improving the mixing effect of the raw material reaction process.

[0043] In addition, a support seat 17 is fixedly installed on the top of the sealing plate 21, a guide rod 19 is fixedly installed on the top of the support seat 17, and a movable seat 18 connected to the transmission rack 54 is sleeved on the outside of the guide rod 19.

[0044] With the above structure, the sliding cooperation between the movable seat 18 and the guide rod 19 can avoid the direction deviation of the transmission rack 54, thereby ensuring the stability of the cyclic sliding process of the three slide bars 23.

[0045] The inner cavity of the splayed slideway 22 is symmetrically rotated with a closing plate 25. The two through holes of the splayed slideway 22 are shielded by the closing plate 25. The closing plate 25 rotates in the through hole of the splayed slideway 22 along with the drive shaft 61.

[0047] Furthermore, the circulation track 3 includes a sealing support 31 disposed in the inner cavity of the reactor 1, the outer wall of the sealing support 31 is sleeved with a spiral slide 32 fixed to the inner wall of the reactor 1, the top of the sealing support 31 is conical, and the raw materials fall on the conical top of the sealing support 31 after being scattered and processed, and fall on the spiral slide 32 along the inclined surface of the conical top. The spiral slide 32 is spirally fixed on the inner wall of the reactor 1, and the sealing support 31 is fixedly installed on the inner wall of the spiral slide 32, and the spiral slide 32 drives the sealing support 31 to be fixed above the conical vortex chamber 9.

[0048] With the above structure, the spiral slide 32 increases the time for the liquid to flow in the reactor 1, thereby increasing the time for the heating process and further ensuring the product quality of the polyaluminium ferric sulfate. The spiral slide 32 increases the fluidity of the liquid.

[0049] The outer wall of the dispersing piece 24 is evenly provided with liquid dispersion slots 26. The liquid dispersion slots 26 arranged circumferentially on the outer wall slope of the dispersing piece 24 make the raw materials falling on the dispersing piece 24 evenly dispersed, thereby improving the effect of liquid dispersion treatment, and further improving the effect of raw material mixing.

[0050] The top of the outer wall of the reactor 1 is evenly embedded with feed ports 13. An exhaust gas discharge port is provided on the outer wall of the reactor 1, a discharge port is provided at the bottom of the outer wall of the reactor 1, and a pipe connected to the finished product tank is installed on the outer wall of the reflux pipe 11. A plug is provided on each feed port, discharge port and exhaust gas discharge port to ensure the sealing of the processing process.

[0051] The working principle of the reactor for preparing polyaluminium ferric sulfate from waste catalyst tail liquid in this embodiment is as follows: first, the driving motor of the active member 57 and the gear 62 and the circulating pump 10 are connected to the power supply through the wire at the same time, so that the two meshing gears 62 drive the two rotating disks 41 to rotate relative to each other through the driving shaft 61, so that the rotating disk 41 drives the slide bar 23 to slide on the inner wall of the eight-shaped slideway 22 through the card slot 42. At the same time, the active member 57 drives the slide bar 56 to slide on the guide rail 55 through the transmission rod 58, so that the guide rail 55 drives the active shaft 51 to swing back and forth after being stressed, so that the active half gear 52 swings back and forth with the active shaft 51, and drives the driven half gear 53 to swing back and forth through the transmission rack 54, so that the driven half gear 53 drives the lever member 46 to swing back and forth through the movable shaft 45, and the direction of the slide bar 23 is adjusted by the lever member 46.

[0052] Then the raw materials are put into the reactor 1 through the feed port at the top of the outer wall of the reactor, so that the raw materials to be mixed are broken up by the breaking piece 24, and the broken up raw materials fall on the sealing support 31, so that the raw materials fall on the outside of the conical vortex bin 9 along the spiral slide 32. Through the power of the circulating pump 10, the liquid in the inner cavity of the reactor 1 enters the inner cavity of the conical vortex bin 9 through the eccentric surge hole 14, enters the circulating pump 10 through the reflux bucket 15 below the conical vortex bin 9, and is brought into the inner cavity of the reflux pipe 11 through the circulating pump 10.

[0053] After repeated circulation of the raw material mixture, it is discharged to the outside through a pipe on the reflux pipe 11 connected to the finished product tank, and finally undergoes crystallization processing.
