Description

Technical Field

[0001] This invention relates to the field of carbon dioxide conversion technology, and in particular to an apparatus and system for preparing a catalyst for directional carbon dioxide conversion. Background Technology

[0002] Carbon dioxide is a carbon oxide compound with the chemical formula CO2. At room temperature and pressure, it is a colorless and odorless gas, or a colorless and odorless gas, but its aqueous solution has a slightly acidic taste. It is also a common greenhouse gas. With the increasing pressure of carbon emissions, converting carbon dioxide into chemicals or fuels can solve the environmental problems caused by the increase in atmospheric CO2 concentration on the one hand, and reduce dependence on fossil fuels on the other.

[0003] Catalysts are required in the process of producing aromatics by hydrogenation of carbon dioxide. For example, patent application CN201910321493.1 discloses a catalyst for the directional conversion of CO2 to produce aromatics. This catalyst has a core-shell structure with a metal oxide core and a molecular sieve shell, and the metal ion center of the organometallic compound is Zn. 2+ Zr 2+ Fe 3+ Co 2+ Ni 2+ Cu 2+ Cr 3+ Mn 2+ One or more of the following: the molecular sieve is one or more of ZSM-5, MCM-41, SAPO, MCM-22, USY, and SBA-15. The preparation process of the metal-organic framework compound A is as follows: one or more of the metal salts are mixed with organic ligands, dissolved and dispersed in a solvent, and hydrothermally treated at 80-200℃ for 1-48 hours. The resulting mixture is obtained by filtration or evaporation of the solvent. When performing solid-liquid separation on the mixture during catalyst preparation, filtration or evaporation of the solvent is used. However, when using filtration alone, a small amount of liquid easily remains on the solid surface, requiring a long filtration time. When using evaporation alone, a large amount of liquid in the solvent needs to be evaporated first, affecting the evaporation efficiency. If filtration is performed until a small amount of liquid remains in the solvent before evaporation, the two solid-liquid separation steps are separated, making continuous solid-liquid separation of a large amount of solvent impossible, resulting in slow solid-liquid separation efficiency. Therefore, the difficulty in improving the efficiency of solid-liquid separation in the mixture lies in how to separate and dry the solid in the filtration section without affecting the filtration efficiency during the filtration process. Summary of the Invention

Detailed Implementation

[0029] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings.

[0030] Reference Figures 1 to 11A catalyst preparation apparatus for directional carbon dioxide conversion includes: a separation tank 1 and a drive shaft 201 rotatably connected within the separation tank 1; multiple sets of separation components, each including a baffle 202 and an inclined filter screen 203, the filter screen 203 being fixedly connected to the baffle 202, both the baffle 202 and the filter screen 203 being fixedly connected to the drive shaft 201; wherein, the baffle 202 on two connected separation components is fixedly connected to the filter screen 203; an inlet tank frame 102 and an outlet tank frame 103, matching a single separation component, are respectively disposed at the lower end and upper end of the separation tank 1; wherein, the baffle 202 is provided with a one-way drain port 2021, i.e., drain port 202. The separator 1 is equipped with a one-way valve and a control port 3. When the control port 3 is opened, the liquid in the separator connected to the control port 3 is discharged from the drain port 2021. The collection port 104 is located at the lower end of the separator 1. The collection port 104 is slidably connected to the collection box 1041. The collection port 104, the liquid outlet rack 103, and the control port 3 are arranged in sequence along the rotation direction of the drive shaft 201. The collection port 104 is equipped with a drying hot air inlet, which is connected to the separator. The separator 1 is fixedly connected to the drive motor 2, and the drive shaft 201 is fixedly connected to the output end of the drive motor 2. The separator 1 is fixedly connected to the cover 101.

[0031] Reference Figures 2 to 5 When using this device, connect the inlet tank 102 to the metal salt solvent storage tank and the outlet tank 103 to the filtration pump. Start the filtration pump to discharge the metal salt solvent in the storage tank through the inlet tank 102, the separator, and the outlet tank 103 in sequence. The metal salt solvent is filtered through the separator.

[0032] When the metal salt solvent passes through the separator, the solid part of the metal salt solvent is filtered by the filter screen 203, and the liquid part moves upward through the filter screen 203 and is sucked away.

[0033] When the drive shaft 201 rotates, it will drive multiple sets of separators to rotate, so that the separators will pass between the liquid inlet rack 102 and the liquid outlet rack 103 in sequence to continuously separate and filter the metal salt solution.

[0034] When the separator enters between the inlet tank 102 and the outlet tank 103, both sides of the separator are sealed to prevent the metal salt solution from entering other separators.

[0035] At this time, heated protective gas is introduced into the collection port 104, causing the protective gas to move in the opposite direction of the rotation of the drive shaft 201. That is, the rotation direction of the separator is opposite to the flow direction of the protective gas. The heated protective gas has a high frequency of contact with the solids on the filter screen 203, and the filter screen 203 is set at an angle. This results in more filtered solids and more contact surface with the gas, leading to a better drying effect on the solids. In other words, the solids can be dried simultaneously while the metal salt solution is being filtered, which improves the drying efficiency of the metal salt solution.

[0036] Reference Figures 10 to 11 The drain port 2021 is not only equipped with a one-way valve, but also has a slidably connected drain slide plate 2022. A baffle spring 2023 is fixedly connected to the drain slide plate 2022. A second magnetic plate 106 is fixed at the bottom of the separation tank 1. The second magnetic plate 106 is located at the end of the control port 3 away from the liquid inlet rack 102. The second magnetic plate 106 and the drain slide plate 2022 are magnetically attracted to each other.

[0037] When the baffle 202 rotates onto the second magnetic plate 106, the drain slide plate 2022 on the baffle 202 moves downward under the influence of the magnetic force of the second magnetic plate 106, blocking the drain port 2021 and preventing the heated gas from entering the filtration pump.

[0038] Reference Figure 6 , Figure 7 A control block 301 is slidably connected to the separation tank 1. The control block 301 matches the control port 3. A control spring 302 and a connecting strip 303 are fixedly connected to both sides of the control block 301. The ends of the control spring 302 and the connecting strip 303 away from the control block 301 are fixedly connected to the separation tank 1. A sliding seat 304 is slidably connected to the separation tank 1. A pressing strip 305 is fixedly connected to the sliding seat 304. The upper end of the pressing strip 305 is in contact with the connecting strip 303. The sliding seat 304 matches the baffle 202. A pressing spring 306 is fixedly connected to the sliding seat 304. The other end of the pressing spring 306 is fixedly connected to the separation tank 1. It should be noted that the filter screen 203 is mesh-shaped and cannot drive the sliding seat 304 to slide.

[0039] When the baffle 202 of the separator rotates away from the liquid inlet tray 102 and the liquid outlet tray 103, the baffle 202 separates the separator. It should be noted that there is still liquid inside the separator at this time.

[0040] To facilitate the discharge of liquid from the separator section, the baffle 202 will be in contact with the sliding seat 304, causing the baffle 202 to push the sliding seat 304 upward. The sliding seat 304 drives the extrusion strip 305 to slide and extrude the connecting belt 303, thereby pulling the control block 301 to slide. The control port 3 opens, and the separator is connected to the outside gas. At this time, under the action of air pressure, the liquid in the separator will enter the space between the inlet tank frame 102 and the outlet tank frame 103 through the drain port 2021 and be sucked by the filtration pump.

[0041] When the baffle 202 leaves the sliding seat 304, the control block 301 resets and blocks the control port 3 under the action of the control spring 302. At this time, the liquid in the separator is discharged, and the metal salt solution in the next separator is filtered.

[0042] Reference Figure 4 , Figure 5 The separator 1 is connected to an end exhaust pipe 4, which is located above the second magnetic plate 106, so that the heated protective gas introduced can be discharged after flowing around the separator 1 for a distance.

[0043] It should be noted that the width of the second magnetic plate 106 is the same as the width of the two separating parts, and the end exhaust pipe 4 is located on the side of the second magnetic plate 106 away from the liquid inlet tray 102.

[0044] During the rotation of the separator, the frequency of the number of drain slide plates 2022 being magnetically attracted changes between two and three sets. When three sets of drain slide plates 2022 are magnetically attracted, the positions of the three sets of drain slide plates 2022 are located at both ends and the middle of the second magnetic plate 106. That is, the two separators on the side of the second magnetic plate 106 near the liquid inlet rack 102 are isolated and sealed, so that the gas introduced into the separator tank 1 is squeezed.

[0045] As the drive shaft 201 rotates, two sets of drain slide plates 2022 are magnetically attracted. At this time, the drain slide plate 2022 on the second magnetic plate 106 that is away from the liquid inlet rack 102 is not magnetically attracted, while the other two drain slide plates 2022 are magnetically attracted. The gas in the separator 1 passes through the drain port 2021 on the second magnetic plate 106 that is away from the liquid inlet rack 102, and is discharged from the end exhaust pipe 4 in a pressure-relief manner.

[0046] At this time, as the drive shaft 201 rotates, the drain slide plate 2022 located in the middle of the three sets of magnetic attraction will pass over the end exhaust pipe 4, block the end exhaust pipe 4, and repeat the state of two to three sets.

[0047] In this rotating state, the gas introduced into the separator 1 can be discharged intermittently, allowing the gas to accumulate first and then be sprayed out in large quantities. The instantaneous gas flow has a better drying effect on the liquid on the solid surface.

[0048] Reference Figure 4 , Figure 5 The separator 1 is fixedly connected to a first magnetic plate 105, which is located between the liquid inlet rack 102 and the liquid outlet rack 103. The width of the first magnetic plate 105 is the same as the width of a single separator, that is, the wall between the liquid inlet rack 102 and the liquid outlet rack 103 can be closed by the first magnetic plate 105, the second magnetic plate 106, and the baffle 202.

[0049] The upper end of the separator 1 is fixedly connected to an opening exhaust pipe 401. The opening exhaust pipe 401 is equipped with a one-way valve. The opening exhaust pipe 401 is located at the end of the first magnetic plate 105 near the liquid inlet tray 102. When the separator rotates, it will carry some of the introduced protective gas. Under the action of the one-way valve in the exhaust pipe 401, this part of the gas may be discharged from the opening exhaust pipe 401 or the filtration pump.

[0050] Reference Figure 8 , Figure 9 A guide cylinder 2071 is fixedly connected to the separator 1. The guide cylinder 2071 is located at the upper end of the collection port 104. An upper sliding magnetic block 207 is slidably connected inside the guide cylinder 2071. A connecting cylinder 204 is fixedly connected to the baffle 202. A lower sliding magnetic block 205 is slidably connected inside the connecting cylinder 204. The lower sliding magnetic block 205 and the upper sliding magnetic block 207 are magnetically attracted. An elastic rope 206 is fixedly connected to the lower end of the lower sliding magnetic block 205. The other end of the elastic rope 206 is fixedly connected to the filter screen 203.

[0051] As the separator rotates, when the lower sliding magnetic block 205 approaches the upper sliding magnetic block 207, it is affected by the magnetic force and moves upward, pulling the elastic rope 206 to extend. When the lower sliding magnetic block 205 continues to slide, and the tension of the elastic rope 206 is greater than the magnetic force between the magnetic blocks, the lower sliding magnetic block 205 separates from the upper sliding magnetic block 207. The lower sliding magnetic block 205 will move downward under the action of the elastic rope 206 and its own gravity. The elastic rope 206 causes the filter screen 203 to shake, so that the solids attached to the filter screen 203 fall into the collection box 1041.

[0052] The beginning exhaust pipe 401 is connected to the end exhaust pipe 4. A guide pipe 402 is fixedly connected to the end exhaust pipe 4. A sliding piston 209 is fixedly connected to the separator 1. A piston block 2091 is slidably connected inside the sliding piston 209. An exhaust slot 2092 is fixedly connected to the sliding piston 209. The sliding piston 209 is connected to the guide pipe 402. The upper sliding magnetic block 207 is connected to the piston block 2091 through a connecting pull rope 208.

[0053] The gas intermittently discharged from the beginning exhaust pipe 401 and the end exhaust pipe 4 will enter the sliding piston 209 through the air guide pipe 402. Under the influence of the gas impact force, the gas pushes the piston block 2091 to slide, so that the piston block 2091 pulls the upper sliding magnetic block 207 through the connecting pull rope 208, promoting the separation of the upper sliding magnetic block 207 and the lower sliding magnetic block 205, so that when the elastic rope 206 vibrates the filter screen 203, it is still located at the upper end of the collection box 1041.

[0054] Reference Figures 1 to 11 A catalyst preparation system for carbon dioxide directional conversion includes a catalyst preparation device for carbon dioxide directional conversion. In use, the inlet tank 102 is connected to a metal salt solvent storage tank, and the outlet tank 103 is connected to a filtration pump. When the filtration pump is started, the metal salt solvent in the storage tank is discharged sequentially through the inlet tank 102, the separator, and the outlet tank 103. The metal salt solvent is filtered through the separator.

[0055] When the metal salt solvent passes through the separator, the solid part of the metal salt solvent is filtered by the filter screen 203, and the liquid part moves upward through the filter screen 203 and is sucked away.

[0056] When the drive shaft 201 rotates, it will drive multiple sets of separators to rotate, so that the separators will pass between the liquid inlet rack 102 and the liquid outlet rack 103 in sequence to continuously separate and filter the metal salt solution.

[0057] When the separator enters between the inlet tank 102 and the outlet tank 103, both sides of the separator are sealed to prevent the metal salt solution from entering other separators.

[0058] At this time, heated protective gas is introduced into the collection port 104, causing the protective gas to move in the opposite direction of the rotation of the drive shaft 201. That is, the rotation direction of the separator is opposite to the flow direction of the protective gas. The heated protective gas has a high frequency of contact with the solids on the filter screen 203, and the filter screen 203 is set at an angle. This results in more filtered solids and more contact surface with the gas, leading to a better drying effect on the solids. In other words, the solids can be dried simultaneously while the metal salt solution is being filtered, which improves the drying efficiency of the metal salt solution.

[0059] This invention, through a rotating separator capable of intermittent sealing, can simultaneously filter out solids from a metal salt solution and dry the moisture on the surface of the solids, thereby improving the drying effect of the metal salt mixture and increasing the collection efficiency of solids in the mixture.
