Description

[0002] In the past decade, electromagnetically stabilized reactors with liquid-solid two-phase flow have been successfully applied in the industrial production of caprolactam. However, the reaction system of the liquid-solid two-phase system is far less common than the gas-liquid-solid three-phase system. However, in the gas-liquid-solid three-phase system, due to the effect of gas, the solid particles cannot maintain a chain state under the action of the electromagnetic field but are fluidized or even over-fluidized. A large number of catalyst particles break free from the constraints of the magnetic field and are carried out with the fluid. If the catalyst is not recycled or supplemented, the catalyst in the bed will inevitably be unsustainable, and the concentration will not be maintained, thus losing the advantage of the electromagnetically stabilized reactor.

[0003] Therefore, for chemical reactions in the gas-liquid-solid three-phase environment, when the solid catalyst exists in the form of solid particles, a slurry bed reactor or a fluidized bed reactor is usually used. Both types of reaction systems require a large and complex catalyst recovery and circulation system.

[0028] See also Figure 3-5 The filter assembly 4 in this embodiment includes a connection frame 41 installed on the right side of the liquid-solid separation cylinder 32 for connection and cooperation, a sealing sleeve 42 correspondingly installed in the hollow part of the connection frame 41 for connection and sealing cooperation, a filter screen 43 correspondingly embedded in the connection frame 41 and connected to the inner side of the sealing sleeve 42, so as to cooperate with the filter screen 43 to achieve auxiliary filtration and improve the solid-liquid separation effect, and a locking structure 44 installed on the upper end of the connection frame 41 and the filter screen 43 for quick disassembly and assembly.

[0031] Further explanation, such as Figure 6 As shown in the figure, in the case of liquid-solid two-phase, the chain arrangement or chain swing of particles under the action of a uniform external magnetic field that does not change with time is conducive to the stable operation of the bed, and the bed under this condition is called a magnetically stabilized bed. Under different magnetic fields, the magnetically stabilized bed of the liquid-solid system has three operating forms, namely, the scattered particle form, the chain form and the magnetic aggregation form. Under different flow rates, the magnetically stabilized bed of the liquid-solid system has four operating states, namely, the non-fluidized state, the stable state, the swinging state and the free motion state. Figure 6 In the process, the ideal liquid-solid contact effect can be achieved by using a magnetically stabilized bed, while the pressure drop is low and the air velocity is high.

[0032] Here’s how it works:

[0033] First, the gas and liquid enter from the gas-liquid inlet 12 provided on the left side of the lower end of the chemical reaction zone b, and after being distributed by the distribution plate 13 provided at the upper end, the gas and liquid will enter the upper part of the chemical reaction zone b, wherein the distribution plate 4 is used to evenly distribute the fluid and block the catalyst particles from entering the lower part of the distribution plate 4;

[0034] When the gas and liquid enter the upper part of the chemical reaction zone b, the operation of several groups of electromagnetic inductors 2 evenly distributed outside the reactor body 11 can be realized through an external control system, wherein each group of electromagnetic coils in the electromagnetic inductor 2 can adjust the magnetic field strength individually, and under the action of the electromagnetic field, gas, liquid and solid will form a three-phase flow state inside the chemical reaction zone b, and perform gas-liquid separation in the gas-liquid separation zone a, wherein the gas will be discharged from the gas outlet 15 provided at the top of the reactor body 11, and the liquid and solid will overflow into the solid-liquid separation system 3 through the short-joint pipe 31 connected to the right side of the upper end of the reactor body 11, that is, into the liquid-solid separation cylinder 32, wherein the short-joint pipe 31 is a downward inclined pipe, the purpose of which is to prevent the gas from entering the liquid-solid separation zone to interfere with the liquid-solid separation operation;

[0035] When the liquid and the solid enter the liquid-solid separation cylinder 32, the control system can be used to operate the special-shaped electromagnetic inductor 36 connected to the conical head at the bottom of the liquid-solid separation cylinder 32 to exert a magnetic field strengthening effect, so that the solid particles inside the liquid-solid separation cylinder 32 are gathered on the conical head at the bottom of the liquid-solid separation cylinder 32 under the action of gravity, and the solid particles can be returned to the catalyst bed of the chemical reaction zone b through the circulation conduit 33, thereby forming a catalyst circulation and replenishing the catalyst concentration in the chemical reaction zone b. Among them, the circulation power of the circulation conduit 33 comes from the density difference between the circulation pipe fluid and the chemical reaction zone b fluid. In order to adjust the size of the circulation volume, a regulating valve 34 is installed in the chemical reaction zone b to achieve flexible flow adjustment, and the end face of the circulation conduit 33 extending into the chemical reaction zone b is an oblique section, the purpose of which is to prevent gas from entering the circulation conduit 33 to interfere with the liquid-solid separation operation. Finally, the separated liquid will be discharged from the overflow port 35 provided on the right side of the upper end of the liquid-solid separation cylinder 32;

[0036] The coil in the special-shaped electromagnetic inductor 36 also serves as a load-bearing support for the liquid-solid separation cylinder 32, and the magnetic field strength can be adjusted individually to magnetically collect and process the catalyst particles in the best way;

[0037] When the catalyst needs to be replaced later, the old catalyst can be discharged through the catalyst discharge port outside the circulation conduit 33, and new catalyst can be injected through the supplementary inlet 14 set on the right side of the lower end of the chemical reaction zone b, so as to achieve the effect of flexible replacement of the waste catalyst;

[0038] In order to further improve the solid-liquid separation effect, a filter assembly 4 is provided inside the upper right side of the liquid-solid separation cylinder 32, that is, when the liquid is discharged, the filter screen 43 connected to the outside of the connection frame 41 will be passed in advance, so that the filter screen 43 assists in liquid filtration and purification, reduces internal solid particles, and improves the liquid separation quality. In addition, the sealing sleeve 42 provided in the hollow part of the connection frame 41 can improve the sealing degree of the side connection of the filter screen 43 and reduce the occurrence of leakage, thereby achieving the advantages of solid-liquid auxiliary filtration and separation and improving the liquid discharge quality.

[0039] At the same time, when the filter 43 is to be disassembled and cleaned later, the pressing frame 446 provided inside the locking structure 44 can be squeezed to make the pressing frame 446 press down the roller 445 connected at the bottom. In this way, the roller 445 can be moved downward as a whole to make the middle part of the roller 445 move out of the vertical extension section of the card slot 442 provided in the middle part of the positioning block 441 to realize the unlocking activity. At the same time, when the roller 445 moves downward, it will be inserted into the interior of the fixed shells 444 on both sides to squeeze the compression springs 447 installed correspondingly inside the fixed shells 444 on both sides. In this way, when the roller 445 moves out of the vertical extension section of the card slot 442, the staff can pull out the filter 43 as a whole to move the filter 43 out of the connecting frame 41 for convenient disassembly. When it is reinstalled later, it only needs to cooperate with the positioning block 441 set at the upper end of the filter 43 and the positioning slot opened at the upper end of the connecting frame 41 443 docking effect, to achieve pre-positioning docking activities, so that the filter 43 and the connecting frame 41 are accurately combined and docked, and when the positioning block 441 moves into the positioning groove 443, it will cooperate with the smooth chamfer on the rear side of the card slot 442 to contact the middle part of the roller 445, and squeeze the roller 445 as a whole, so that the roller 445 can again realize the squeezing of the compression spring 447 provided inside the fixed shell 444. In this way, when the positioning block 441 docks with the outer side of the positioning groove 443, the compressed compression spring 447 will rebound to realize the overall upward push of the roller 445, so that the middle part of the roller 445 is correspondingly inserted into the vertical extension section on the front side of the card slot 442, to achieve mutual abutment and locking, to ensure the firmness of the connection and combination state of the filter 43 and the connecting frame 41, thereby achieving the advantages of convenient disassembly and assembly of the connecting frame 41 and the filter 43 and improving the convenience of use.

[0040] The utility model provides a gas-liquid solidification magnetic induction stabilization device, which realizes the separation of gas and liquid-solid in the gas-liquid separation zone a by constructing a gas-liquid-solid three-phase fluid movement system, thereby creating conditions for subsequent liquid-solid separation; liquid-solid separation is realized under the action of the solid-liquid separation system 3, and the solid particle fluid is guided to flow back to the chemical reaction zone b through the circulation conduit 33, thereby realizing the closed circulation of the catalyst, avoiding the need to configure complex and large catalyst recovery and circulation systems for systems such as slurry beds and fluidized beds, and providing a strong guarantee for the continuous production of chemical companies, and a filtering component 4 is provided, through the filter screen 43 provided inside, solid-liquid auxiliary filtering and separation is achieved, the liquid separation quality is improved, and the card slot 442 provided inside the locking structure 44 and the roller 445 have a flexible card connection effect, the filter screen 43 and the connecting frame 41 can be conveniently disassembled and assembled, and the overall convenience of use is improved.
