Description

Technical Field

[0001] The invention relates to the technical field of heteropolyacid removal, and in particular to a reaction system and method for removing trace heteropolyacids based on an ion exchange sedimentation method. Background Art

[0002] Heteropolyacids are a class of oxygen-containing polyacids composed of heteroelements (such as P, Si, Fe, Co, etc.) and polyelements (such as Mo, W, V, Nb, Ta, etc.) coordinated and bridged by oxygen elements in a certain structure. They have high catalytic activity and redox properties. They are a new type of multifunctional catalyst used for aromatic alkylation and dealkylation reactions, esterification reactions, dehydration / combination reactions, redox reactions, as well as ring opening, condensation, addition and etherification reactions. Heteropolyacids have been widely valued by researchers in the field of catalytic research due to their unique acidity, "quasi-liquid phase" behavior, and multifunctionality (acid, oxidation, photoelectrocatalysis).

[0003] The metallic compound is at least composed of at least one metal atom and / or at least one part or at least one metal ion and / or at least one counterion and / or at least one part. For the reaction of a wide range, after the reaction is completed, it is usually difficult to remove the heteropolyacid catalyst or its residue from the reaction mixture, and often requires difficult extraction procedures, recrystallization, membrane filtration or distillation steps to remove the catalyst or its residue.

[0004] The invention patent with publication number CN102146516A discloses the removal of metal compounds, including contacting the mixture with a heteropoly acid or heteropoly acid anion, thereby generating a precipitate including the heteropoly acid or heteropoly acid anion and the metal compound and / or its components.

[0005] Existing heteropolyacids are generally removed by combining with metal anions. This method generally forms precipitation that falls into the sedimentation tank. Existing devices generally use a large horizontal auger for cleaning. On the one hand, this cleaning method has low cleaning efficiency, and its cleaning method cannot be combined with the reaction of the heteropolyacid, so that the reaction and cleaning require different driving mechanisms, resulting in bloated equipment and slow response. Moreover, this cleaning mechanism is generally set in the sedimentation tank. After long-term use, it is easily corroded by the reaction solution. However, it is set inside the sedimentation tank, which is not convenient for quick disassembly and replacement, affecting work efficiency. Summary of the invention

Then, the micro motor 23 is controlled by the controller 32 to start, and the micro motor 23 drives the sealing plate 22 at the bottom of the sedimentation tank 21 to rotate, and the bottom opening of the sedimentation tank 21 is opened, so that the precipitation and residual solution in the sedimentation tank 21 are discharged into the collecting tank 11;

[0063] Step 4: After the discharge is completed, the movable plate 38 is driven to move by the stepper motor 33, and then the drive assembly 4 is driven to move until the position sensor 48 at the bottom of the transmission rod 44 corresponds to the sensor receiver in the polygonal connecting groove. At this time, the two synchronous telescopic cylinders 63 on the L-shaped plate 61 are started, and the telescopic cylinders 63 drive the connecting block 74 to move upward through the connecting ring 75 until the polygonal plug 47 at the bottom of the transmission rod 44 is inserted into the polygonal connecting groove. At this time, the other drive motor 41 on the drive assembly 4 is started by the controller 32, and the other drive motor 41 is driven by the first gear. The wheel 42 drives the transmission rod 44 to rotate, and then drives the transmission column 71 to rotate through the connecting block 74, and the transmission column 71 drives the auger blade 81 to rotate to clean the opening of the sedimentation tank 21. At the same time, the transmission column 71 drives the cleaning brush 93 on the arc plate 91 to rotate to clean the inner wall of the sedimentation tank 21. At the same time, the movable plate 38 is driven to move by the stepping motor 33, and the movable plate 38 drives the driving assembly 4 to move, and then drives the transmission assembly 7 to move, so that the first cleaning member 8 and the second cleaning member 9 can cooperate to clean the sediment attached to the inner wall of the sedimentation tank 21 into the collecting tank 11;

[0064] Step 5: After the reaction of the current stage is completed, the fixing plate 31 is moved upward until the first dovetail block 35 on the fixing plate 31 is separated from the first dovetail groove 13 on the bracket 1. At this time, the horizontal adjustment component 3 is separated from the reaction box 2, and then the card block 56 is pressed and pressed into the groove 55 to separate the card block 56 from the card groove 59. Then the baffle 57 is moved until the second dovetail block 58 on the baffle 57 is separated from the second dovetail groove 54 on the placement plate 51. At this time, the baffle 57 can be separated from the ion exchange resin plate 53, and the limit of the ion exchange resin plate 53 can be released, so that the ion exchange resin plate 53 is easy to disassemble and replace. The first cleaning piece 8 and the second cleaning piece 9 need to be replaced after long-term use. After the horizontal adjustment component 3 is disassembled, the connecting component 6 can be moved upward so that the first cleaning part 8 and the second cleaning part 9 on the transmission component 7 are separated from the reaction box 2. At this time, the auger blade 81 is twisted in reverse to separate the screw groove 713 from the screw rod 82, and the auger blade 81 can be disassembled and replaced. Then the limiting card plate 78 is moved upward to compress the return spring 79, and then the arc plate 91 is moved until the arc plate 91 is separated from the annular limiting plate 712, and then the limiting card plate 78 is continued to be moved until the limiting card plate 78 is separated from the arc plate 91. At this time, the positioning strip 92 on the arc plate 91 can be separated from the positioning groove 711 on the transmission column 71, so that the cleaning brush 93 on the arc plate 91 can be disassembled and replaced.

[0065] The polygonal plug rod 47 on the above-mentioned transmission rod 44 corresponds to the polygonal connecting groove on the connecting block 74 in the initial state. During the movement of the transmission assembly 7, one of the drive motors 41 drives the transmission sleeve 45 to rotate, and the other drive motor 41 keeps the transmission rod 44 stationary through the first gear 42, so that when the transmission rod 44 is finally connected to the connecting block 74, there is basically no misalignment between the polygonal connecting groove and the polygonal plug rod 47.

[0066] The length of the above-mentioned positioning groove 711 is greater than the length of the positioning strip 92. When the arc plate 91 is inserted into the groove on the annular limit plate 712, one end of the positioning strip 92 contacts one end of the positioning groove 711. When the arc plate 91 needs to be disassembled, the arc plate 91 can be moved in the reverse direction to move the positioning strip 92 in the positioning groove 711, so that the arc plate 91 can be separated from the annular limit plate 712.
