Description

Technical Field

[0002] Reactor waste recycling primarily refers to the reuse or resource-based treatment of waste residues generated during chemical production. This waste includes substandard products, unsaleable byproducts, reactor bottoms, filter cake residue, spent catalysts, and more. Recycling waste residue not only reduces waste emissions but also generates significant economic benefits.

[0003] In the prior art, the waste residue in the waste liquid has a complex composition. When recovering germanium from the reaction waste liquid, it needs to be alkali washed and then acidified. However, when the waste residue after alkali washing is transported to the acidification reaction liquid for reaction, part of the alkali washing reaction liquid will drip into the acidification reaction liquid, thereby affecting the acidification effect, resulting in the inert and harmful impurities in the waste residue cannot be effectively removed, affecting the reaction activity of the waste residue as a new germanium reagent.

[0004] The waste residue after the above treatment can be used as a new germanium reagent. Its structural composition is relatively stable and has high reactivity. Taking advantage of the characteristics of germanium oxide as an amphoteric compound, the inert and harmful impurities in the waste residue can be better removed through alkaline washing and acidification, so that the waste residue has better reactivity as a new germanium reagent.

[0021] The beneficial effects of the present invention are:

[0022] (1) The present invention collects the alkaline washing liquid remaining in the waste residue after alkaline washing, so that the alkaline washing liquid is circulated into the alkaline washing chamber and discharged at the same time, and then acidification is performed to prevent part of the alkaline washing reaction liquid from dripping into the acidified reaction liquid, thereby affecting the acidification effect, resulting in the inert and harmful impurities in the waste residue cannot be effectively removed, affecting the reaction activity of the waste residue as a new germanium reagent;

[0035] First, the reaction waste liquid is placed in the centrifuge for preliminary filtration. After filtration, the waste residue is collected, and then the collected waste residue is placed in the cleaning chamber of the reaction tank 1 through the feed port. Water is transported to the cleaning chamber through the liquid inlet, and the servo motor 5 is started to drive the rotating shaft 6 and the stirring blade 7 to stir. After the stirring is completed, the waste liquid is discharged through the waste liquid port. By starting the first solenoid valve, the cleaned waste residue enters the alkaline washing chamber through the first discharge pipe 13. When the rotating shaft 6 rotates, it drives the rotating rod 8 and the stirring rod 10 to rotate, so that the waste residue is The inside of the alkali washing chamber is fully reacted. After the alkali washing is completed, the alkali washing liquid is discharged from the waste liquid port, and then the second electric push rod 33 is started to drive the baffle 32 to move into the groove, exposing the moving block 15 inside the top of the moving port. The cleaned waste residue falls into the inside of the moving block 15 and falls onto the moving filter plate 16.

The first electric push rod 23 drives the moving block 15, the filter plate 16 and the third electric push rod 21 to move up and down in the moving port, so that the waste residue inside the moving block 15 is removed. The alkali washing liquid adhering to and remaining on the waste residue is shaken up and down to leak into the collecting block 17 through the filter plate 16 for collection. After the collection is completed, the first motor 30 drives the movable rod 29 and the gear 28 to rotate, so that the first rack 26 and the second rack 27 drive the fixed block 25 and the connecting rod 24 to move closer to each other, so that the collecting block 17 moves from the moving port to the inside of the groove, and then the third electric push rod 21 is started to drive the filter plate 16 to move into the groove, so that the first magnetic block 19 and the second magnetic block 20 are separated to separate the moving port. The waste residue after alkali washing is exposed, so that the waste residue after alkali washing falls into the second discharge pipe 14, and the waste residue after alkali washing is transported to the acidification chamber through the second solenoid valve.

[0039] When the waste residue inside the cleaning chamber is cleaned, the cleaned waste residue is transported from the first discharge pipe 13 to the inside of the alkali washing chamber for reaction through the first solenoid valve. When the alkali washing is completed, the alkali washing liquid is discharged from the waste liquid port, and the baffle 32 is driven by the second electric push rod 33 to move to the inside of the groove, so that the moving port and the moving block 15 are exposed, so that the waste residue after alkali washing falls onto the inner wall of the moving block 15 and the filter net, so that the waste residue is filtered again.

The first motor 30 drives the movable rod 29 and the gear 28 to rotate, so that the first rack 26 and the second rack 27 move closer to each other, so that the fixed block 25 moves along the inner wall of the bottom of the groove, and drives the connecting rod 24 and the collecting block 17 to move toward the inside of the groove, so as to facilitate the movement of the alkaline washing liquid inside the collecting block 17 to the bottom of the circulation structure 31, and facilitate the transportation of the alkaline washing liquid to the inside of the alkaline washing chamber through the circulation structure 31, and discharge it together with the alkaline washing liquid inside the alkaline washing chamber, so as to improve the efficiency of the alkaline washing liquid discharge.

The alkaline washing liquid inside the collecting block 17 is transported by the circulation pipe 311 through the circulation pump 312 and the elastic telescopic tube 313. By starting the second electromagnetic block valve, the recovered alkaline washing liquid is transported to the inside of the alkaline washing chamber, thereby facilitating the simultaneous treatment of the collected alkaline washing liquid and the alkaline washing liquid inside the alkaline washing chamber, so that the collecting block 17 can collect again when the waste slag metal is alkaline treated.

The installation box 36 is conveniently divided into a first storage chamber and a second storage chamber through the installation block 38. Since the two liquid outlets are respectively arranged corresponding to the first storage chamber and the second storage chamber, it is convenient to transport the alkaline washing liquid and acidifying liquid inside the first storage chamber and the second storage chamber from the liquid outlet on one side of the installation box 36 to the alkaline washing chamber and the acidifying chamber inside the reaction tank 1, so as to facilitate the rapid replenishment of the alkaline washing liquid and the acidifying chamber at the same time, thereby facilitating the improvement of the effect of the waste residue re-acidification and alkaline washing.

One side of the threaded rod 40 is rotatably connected to the inner wall of the mounting block 38, and the threaded rod 40 is threadedly connected to an end of the second motor 39. The top of the movable block 41 is slidably connected to the inner wall of the top of the mounting block 38, and the bottom end of the movable block 41 is hinged with a push plate 42. One end of the push plate 42 is hinged with a sealing block 43. A moving opening is provided at the bottom of the mounting block 38 near the sealing block 43. The push plate 42 extends through the moving opening to the inside of the second storage cavity. The sealing block 43 is located at the liquid outlet, and is located on the upper and lower sides of the fixed plate 37. A support rod 44 is fixedly connected to one side of the sealing block 43. An arc-shaped opening is provided in the middle of the fixed plate 37. The arc-shaped opening passes through the bottom of the mounting box 36, and the support rod 44 is located inside the arc-shaped opening.

[0047] The threaded rod 40 is driven to rotate by the second motor 39, so that the movable block 41 moves along the inner wall of the mounting block 38, so that the push plate 42 is deflected, and the push plate 42 pushes the sealing block 43 on the side of the second storage chamber to move downward, so that one end of the sealing block 43 moves to the bottom of the mounting box 36 through the arc-shaped opening at the bottom of the mounting box 36, exposing the liquid outlet of the first storage chamber, and the sealing block 43 on the side of the first storage chamber is driven to move toward the inside of the arc-shaped opening inside the mounting block 38 through the action of the support rod 44, so that the liquid outlet on the side of the first storage chamber is exposed, thereby facilitating the alkaline washing liquid and acidifying liquid inside the mounting box 36 to be simultaneously transported to the inside of the alkaline washing chamber and the acidifying chamber through the liquid outlet and the feed port, facilitating rapid replenishment and improving working effect.

[0048] The present invention also provides a method for using the recovery device of the reactor, comprising the following steps:

[0049] Step 1: First, the reaction waste liquid is placed in the centrifuge for preliminary filtration. After filtration, the waste residue is collected, and then the collected waste residue is placed in the cleaning chamber of the reaction tank 1 through the feed port, and water is transported into the cleaning chamber through the liquid inlet. The servo motor 5 is started to drive the rotating shaft 6 and the stirring blade 7 to stir. After the stirring is completed, the waste liquid is discharged through the waste liquid port. By starting the first solenoid valve, the cleaned waste residue enters the alkaline washing chamber through the first discharge pipe 13. When the rotating shaft 6 rotates, it drives the rotating rod 8 and the stirring rod 10 to rotate, so that the waste residue is fully reacted in the alkaline washing chamber;

[0050] Step 2: After the alkaline washing is completed, the alkaline washing liquid is discharged from the waste liquid port, and then the second electric push rod 33 is started to drive the baffle 32 to move into the groove, exposing the moving block 15 inside the top of the moving port, and the cleaned waste residue falls into the inside of the moving block 15, and then is magnetically connected to the second magnetic block 20 through the first magnetic block 19. The first electric push rod 23 drives the moving block 15, the filter plate 16 and the third electric push rod 21 to move up and down in the moving port, so that the waste residue inside the moving block 15 shakes up and down, and the alkaline washing liquid adhering to the waste residue and the residual alkaline washing liquid leaks into the collecting block 17 through the filter plate 16 and enters the collecting block 17. After the collection is completed, the first motor 30 drives the movable rod 29 and the gear 28 to rotate, so that the first rack 26 and the second rack 27 drive the fixed block 25 and the connecting rod 24 to move closer to each other, so that the collection block 17 moves from the moving opening to the inside of the groove. When the collection block 17 moves to the bottom of the elastic telescopic tube 313, the first electric telescopic rod 315 is started again to drive the elastic telescopic tube 313 to extend into the inside of the collection block 17. The alkaline washing liquid in the collection block 17 is transported from the circulation pipe 311 to the inside of the alkaline washing chamber through the circulation pump 312 and the elastic telescopic tube 313.

[0051] Step 3: Start the third electric push rod 21 to drive the filter plate 16 to move into the groove, so that the first magnetic block 19 and the second magnetic block 20 are separated to expose the moving port, so that the waste residue after alkali washing falls into the second discharge pipe 14, and the waste residue after alkali washing is transported to the acidification chamber through the second solenoid valve. At the same time, the rotation of the stirring shaft 9 and the stirring rod 10 allows the waste residue to fully react with the acidifying liquid for acidification. After the acidification is completed, the acidifying liquid is discharged from the delivery pipe 4, and the acidified waste residue is discharged from the slag outlet 3;

[0052] Step 4: When alkali washing and acidification are needed again, the protective plate 35 is driven to move toward the inside of the fixed groove by the second electric telescopic rod 34 to expose the feed port, and then the second motor 39 is started to drive the threaded rod 40 to rotate, so that the movable block 41 moves along the inner wall of the mounting block 38, driving the push plate 42 to deflect, so that the sealing block 43 moves downward, and the sealing block 43 on one side of the second storage chamber moves downward to the outside of the mounting box 36 through the arc-shaped opening, exposing the liquid outlet on one side of the second storage chamber, and at the same time, the sealing block 43 on one side of the first storage chamber is driven to move toward the arc-shaped opening by the support rod 44, exposing the liquid outlet on one side of the first storage chamber, and the alkali washing liquid inside the first storage chamber and the acidifying liquid inside the second storage chamber enter the interior of the alkali washing chamber and the acidifying chamber respectively through the liquid outlet and the feed port, so as to facilitate alkali washing and acidification of the waste residue again;

[0053] Step 5: Recrystallize the waste residue after alkali washing and acidification, then dry, grind and roast the waste residue, and finally put the treated waste residue into the reaction as a new germanium reagent.

[0054] Working principle: first put the reaction waste liquid into the centrifuge for preliminary filtration, collect the waste residue after filtration, and then put the collected waste residue into the cleaning chamber of the reaction tank 1 through the feed port, and deliver water to the cleaning chamber through the liquid inlet, start the servo motor 5 to drive the rotating shaft 6 and the stirring blade 7 to stir, and after the stirring is completed, the waste liquid is discharged through the waste liquid port, and the cleaned waste residue is allowed to enter the alkaline washing chamber through the first discharge pipe 13 by starting the first solenoid valve. When the rotating shaft 6 rotates, it drives the rotating rod 8 and the stirring rod 10 to rotate, so that the waste residue is fully reacted in the alkaline washing chamber. After the alkaline washing is completed, The alkaline washing liquid is discharged from the waste liquid port, and then the second electric push rod 33 is started to drive the baffle 32 to move into the groove, exposing the moving block 15 inside the top of the moving port. The cleaned waste residue falls into the inside of the moving block 15, and then is magnetically connected to the second magnetic block 20 through the first magnetic block 19. The first electric push rod 23 drives the moving block 15, the filter plate 16 and the third electric push rod 21 to move up and down in the moving port, so that the waste residue inside the moving block 15 shakes up and down, and the alkaline washing liquid adhered to the waste residue and the residual alkaline washing liquid leaks through the filter plate 16 into the collection block 17 for collection. After the collection is completed, the first electric push rod 23 is used to remove the waste residue. The machine 30 drives the movable rod 29 gear 28 to rotate, so that the first rack 26 and the second rack 27 drive the fixed block 25 and the connecting rod 24 to move closer to each other, so that the collecting block 17 moves from the moving port to the inside of the groove. When the collecting block 17 moves to the bottom of the elastic telescopic tube 313, the first electric telescopic rod 315 is started to drive the elastic telescopic tube 313 to extend into the inside of the collecting block 17, and the alkaline washing liquid inside the collecting block 17 is transported from the circulating pipe 311 to the inside of the alkaline washing chamber through the circulating pump 312 and the elastic telescopic tube 313. The third electric push rod 21 is started to drive the filter plate 16 to the groove. The internal movement separates the first magnetic block 19 from the second magnetic block 20 to expose the moving port, so that the waste residue after alkali washing falls into the second discharge pipe 14, and the waste residue after alkali washing is transported to the acidification chamber through the second solenoid valve. At the same time, the rotation of the stirring shaft 9 and the stirring rod 10 allows the waste residue to fully react with the acidifying liquid for acidification. After the acidification is completed, the acidifying liquid is discharged from the conveying pipe 4, and the acidified waste residue is discharged from the slag outlet 3. The waste residue after alkali washing and acidification is recrystallized, and then the waste residue is dried, ground, and roasted. Finally, the treated waste residue is used as a new germanium reagent and put into the reaction.

[0055] When alkali washing and acidification are needed again, the protective plate 35 is driven by the second electric telescopic rod 34 to move into the fixed groove to expose the feed port, and then the second motor 39 is started to drive the threaded rod 40 to rotate, so that the movable block 41 moves along the inner wall of the mounting block 38, driving the push plate 42 to deflect, so that the sealing block 43 moves downward, and the sealing block 43 on one side of the second storage chamber moves downward to the outside of the mounting box 36 through the arc-shaped opening, exposing the liquid outlet on one side of the second storage chamber, and at the same time, the sealing block 43 on one side of the first storage chamber is driven by the support rod 44 to move into the arc-shaped opening to expose the liquid outlet on one side of the first storage chamber, and the alkali washing liquid inside the first storage chamber and the acidifying liquid inside the second storage chamber enter the interior of the alkali washing chamber and the acidifying chamber respectively through the liquid outlet and the feed port, so as to facilitate alkali washing and acidification of the waste residue again.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
