Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chemical machinery and equipment, and particularly relates to a fixed continuous bed multi-fluid material continuous circulation distribution valve. BACKGROUND

[0002] In modern industrial production, continuous beds are widely used in many fields such as chemical industry, pharmaceutical industry, environmental protection and food industry. Due to the diversity of application scenarios, continuous beds face many complex situations in different fields and production processes, such as different numbers of reaction towers, different types and flow rates of materials to be transported, and different process flows. The existing distribution devices and methods have obvious limitations when facing these complex situations.

[0003] The existing continuous beds can be roughly divided into two categories according to their device characteristics: one is an analog continuous bed using a valve array control, and the other is a mobile continuous bed driving large reaction tower groups to rotate intermittently.

[0004] The characteristics of the analog continuous bed technology are as follows: each reaction tower group in each reaction device is fixedly installed according to a certain layout, each tower is connected with multiple materials by pipelines, and is controlled by valves, and the towers are connected by pipelines and controlled by valves according to the series-parallel process requirements. In operation, the on / off state of the valves on each pipeline is frequently switched to realize the cyclic operation of the production process. The advantage is that large reaction towers can be fixedly installed, and process adjustment can be realized by changing the pipeline connection, but the disadvantage is that there are many pipelines, the connection is complex, and more valves and controllers are used for each pipeline to form a "valve array", which is complex to control, and the equipment investment, failure rate and maintenance rate are greatly increased.

[0005] The material distribution device of the mobile continuous bed is connected by a fixed part and a rotatable part, and the material distribution required by the process is realized in the internal structure of the distribution device. The reaction tower group in the overall reaction device is arranged in a ring type and installed on a ring track, and connected with the rotating part of the distribution device through a pipeline. During operation, the entire reaction tower group is synchronously switched and rotated with the rotating part of the distribution device and the connecting pipeline, and finally the entire production process is completed and the circulation operation is realized. The mobile continuous bed has the advantages of greatly reducing the number of connecting pipelines and valves, and the overall reaction device has a more simple and reasonable layout and a more stable operation compared with the simulated continuous bed. However, the reaction tower group, the distribution device rotating part and the connecting pipeline must be gap-rotated on the track during switching, and the weight to be driven is large. Especially for large chemical production devices such as adsorption, the overall weight of the reaction tower, the filling material and the auxiliary devices, and the fluid material in the reaction tower and the pipeline, can be as high as nearly one thousand tons. During switching and rotation, frequent starting and stopping are required, which not only requires a large amount of foundation engineering and high quality, but also requires large and complex equipment with large power. The overall operation has high energy consumption and long switching time. Since the reaction tower group must be rotated and operated on the track, it is difficult or impossible to pressurize through a pump in the middle of the series-connected towers when multiple towers are connected in series, which greatly limits the application of multi-stage series process. Therefore, it is of great practical significance and urgency to develop a high-efficiency distribution valve system for continuous reaction tower groups in multiple fields and an operation method thereof, which can overcome the above-mentioned defects. SUMMARY

[0006] The purpose of the present application is to provide a lightweight, high-efficiency fluid material distribution valve suitable for continuous reaction tower groups in multiple fields, to solve the problems of complex structure, large volume, heavy weight, large amount of foundation engineering, high investment, high energy consumption and inconvenient process adjustment of the existing distribution device, and to improve the key technical equipment in the continuous bed system.

[0007] The technical solution of the distribution valve system structure: the distribution valve system of the present application is composed of an upper valve body (86), a lower valve body (87) and other accessories. The installation support (2) is fixedly installed on the concrete ground, and is divided into three platforms, each platform having a circular mounting hole and surrounding bolt holes. The upper platform is fixedly installed with a stepping reducer (3) through bolts, the middle platform is fixedly installed with an upper fixing disc (4) of the upper valve body (86), and the lower platform is fixedly installed with a lower fixing disc (8) of the lower valve body (87). The reducer drive shaft (18) of the stepping reducer (3) is connected with the upper end of the upper valve body drive shaft (15) of the upper valve body (86) through a shaft coupling, the lower end of the upper valve body drive shaft (15) of the upper valve body (86) is connected with the upper end of the lower valve body drive shaft (16) of the lower valve body (87) through a shaft coupling, and finally the rotating distribution mechanism is driven to rotate step by step by the stepping reducer (3).

[0008] The upper valve body (86) and the lower valve body (87) have the same parts and assembly structure, which is convenient for unified manufacturing and mutual replacement. The lower valve body (87) mainly includes a lower fixed disc (8) (including assembly accessories), a lower rotating disc (7) (including assembly accessories), and other assembly accessories. The lower fixed disc (8) has a central shaft hole (36) on the front surface, and the shaft hole (36) has a pair of front bearing holes (35) and back bearing holes (33) of the installed and aligned thrust ball bearings (34), (24) on the upper and lower sides. Radially outward from the shaft hole (36), there are eight annular grooves in sequence, including a support spring sliding groove (37), a fixed disc water ring sliding groove (38), a fixed disc annular water collecting groove (39), a fixed disc sealing ring B sliding groove (41), a B material annular flow groove (42), a sealing ring A sliding groove (43), an A material annular flow groove (44), and a fixed disc annular sealing ring sliding groove (45). Each annular groove has a specific function, such as the support spring sliding groove (37) having a support spring adjusting bolt group (88) in the support spring tension adjusting screw hole group at the bottom, which is used to adjust the tension of the support spring (56); the fixed disc annular water collecting groove (39) having an annular water collecting groove drainage screw hole group (40) at the bottom, which is used to drain possible water. The B material annular flow groove (42) and the A material annular flow groove (44) have discharge main pipe installation holes at the bottom, which are used to install the B material discharge main pipe (12) and the A material discharge main pipe (10), respectively. The lower fixed disc (8) has a support platform installation through hole at the outermost side, which is used to be fixed on the support platform.

[0009] The most middle of the front of the lower rotary disc (7) is a rotary disc shaft hole (57) (through hole), and there are six annular grooves distributed outward in turn, including a thrust ball bearing and support spring mounting groove (58), a rotary disc water isolation ring clamping groove (59), a lower rotary disc annular water collecting groove (60), a rotary disc sealing ring B mounting groove (62), a rotary disc sealing ring A mounting groove (63), and a rotary disc annular sealing gasket mounting groove (64). The annular face A (95) is between the rotary disc sealing ring A mounting groove (63) and the rotary disc annular sealing gasket mounting groove (64), and the annular face B (96) is between the rotary disc sealing ring B mounting groove (62) and the rotary disc sealing ring A mounting groove (63). The inner surface of the shaft hole (36) has a cylindrical pin clamping groove set (68) matched with the cylindrical pin on the drive shaft, so that the lower rotary disc (7) can move axially along the drive shaft but cannot rotate relatively. Each annular groove also has a corresponding function, such as the thrust ball bearing and support spring mounting groove (58) mounting the thrust ball bearing (54), the support spring frame (55), and the support spring (56); the lower rotary disc annular water collecting groove (60) has a rotary disc annular water collecting groove drain screw hole set (61) at the bottom; the rotary disc sealing ring mounting groove places the sealing ring; the rotary disc annular sealing gasket mounting groove (64) has a distribution hole set (65) corresponding to the inlet and outlet flange pipe mounting hole on the lower fixed disc (8). The annular face B (96) has a B material conversion hole set (67) corresponding to the B material annular flow groove (42) on the lower fixed disc (8), and the annular face A (95) has an A material conversion hole set (66) corresponding to the A material annular flow groove (44) on the lower fixed disc (8).

[0010] After assembly, the A material annular flow groove (44) of the lower fixed disc (8), the annular face A (95) of the lower rotary disc (7), and the annular sealing gasket (50) and the sealing ring A (51) on both sides jointly constitute an A material annular flow chamber. In the A material annular flow chamber, one side of the chamber is connected with the A material inlet and outlet manifold on the opposite side of the lower fixed disc (8) through the A material outlet manifold mounting hole (30) at the bottom of the A material annular flow groove (44) of the lower fixed disc (8), the A material outlet manifold mounting hole A (31), and further connected with the corresponding flange pipe.

[0011] Similarly, the B material annular flow groove (42) of the lower fixed disc (8), the annular surface B (96) of the lower rotating disc (7), and the sealing ring A (51) and the sealing ring B (52) on both sides jointly constitute a B material annular flow chamber. In the B material annular flow chamber, one side of the chamber is communicated with the B material inlet and outlet pipe installed on the opposite side of the lower fixed disc (8) through the B material outlet main pipe installation hole (32) at the bottom of the B material annular flow groove (42), and is connected with the corresponding lower distribution hole through the B material lower distribution pipe (84) on the opposite side of the lower rotating disc (7) and is further communicated with the corresponding flange pipe.

[0012] The rotating distribution mechanism jointly constituted by the upper rotating disc (5), the lower rotating disc (7), the process pipeline, and the accessory (6), wherein the upper rotating disc (5) and the lower rotating disc (7) are in concentric positions; the upper distribution hole A (121), the upper distribution hole B (122), the upper distribution hole C (123), the upper distribution hole D (124), the upper distribution hole E (125), and the upper distribution hole F (126) of the upper rotating disc (5) are respectively corresponding to the lower distribution hole A (181), the lower distribution hole B (182), the lower distribution hole C (183), the lower distribution hole D (184), the lower distribution hole E (185), and the lower distribution hole F (186) of the lower rotating disc (7) with the same center, and the relative positions remain unchanged in the rotating switching process. According to the process requirements, the A and B material series pipes can be connected with the lower distribution holes on the different lower rotating discs (7) and the upper distribution holes on the upper rotating disc (5) respectively, that is, the series relationship of the A and B material flow is completed according to the process requirements.

[0013] When the step reducer (3) drives the switching, the upper and lower rotating discs rotate simultaneously. The distribution holes on the upper and lower rotating discs are communicated with the inlet and outlet flange pipes on the upper and lower fixed discs one by one, and after the switching is completed, the distribution holes on the upper and lower rotating discs are re-communicated with the inlet and outlet flange pipes on the fixed discs one by one in the new positions, so as to realize the circulation operation of the same process in the reaction tower group.

[0014] After the upper valve body (86) and the lower valve body (87) are assembled, the upper valve body (86) serves as the A material inlet distribution valve body, and the corresponding lower valve body (87) serves as the A material outlet valve body, and vice versa; the upper valve body (86) serves as the B material inlet distribution valve body, and the corresponding lower valve body (87) serves as the B material outlet valve body, and vice versa.

[0015] The operation mode is: the operation method of the distribution valve system of the application can realize the circulation distribution of multiple materials in different numbers of reaction towers based on the above structure. Taking a typical adsorption and desorption process as an example, the inlets and outlets of the upper and lower valve bodies are numbered. According to the process requirements, the synchronous rotation of the rotating distribution mechanism composed of the upper and lower rotating discs and the connecting pipe fittings is driven by the step reducer (3), so as to realize the switching of the material distribution path. In the starting stage, the distribution hole groups on the upper and lower rotating discs are respectively aligned with the feed flange pipes and the discharge flange pipes on the upper and lower fixed discs, and the materials flow according to the set process path. For example, A material flows from the A material feed buffer tank (89) through the A material feed main pipe (9) into the upper fixed disc A material annular flow groove (91) of the upper fixed disc (4) in the upper valve body (86), and then flows through the A material conversion hole, the distribution pipe, the distribution hole, the feed flange pipe into the corresponding reaction tower, and finally flows out of the device through the discharge port, the pump, and the discharge flange pipe, the distribution hole, the distribution pipe, the A material annular flow groove (44) and the A material discharge main pipe (10) of the lower valve body (87); B material flows in the same way. When the reaction reaches the specified time, the upper and lower rotating discs are synchronously rotated counterclockwise by 60 degrees, and the next process state is switched, and the material distribution path is correspondingly changed. After six switching, the whole device returns to the starting process state, and realizes the circulation operation.

[0016] The distribution valve system of the application is not only suitable for the case of two materials and six reaction towers, but also can be expanded according to actual needs. When multiple materials need to be processed, the same number of annular flow grooves and sealing ring sliding grooves as the number of material types are added to the fixed disc, and the corresponding annular surface, conversion hole group and sealing ring mounting groove are added to the rotating disc, so that the simultaneous processing of multiple materials can be realized. When the number of reaction tower groups required is different, the same number of discharge flange pipe mounting holes and discharge flange pipes as the number of actual reaction towers in the reaction tower group are matched on the annular sealing gasket sliding groove and the annular sealing gasket of the upper and lower fixed discs, and the corresponding number of conversion holes and distribution holes are matched in each conversion hole group on the upper and lower rotating discs, so that the material distribution of the corresponding number of reaction towers can be realized. At the same time, the distribution valve device of the application is not limited to the process in this example, and can be easily adjusted to multiple series and parallel reaction processes by adjusting the position of the upper and lower distribution holes connected by the series pipes, increasing the number of series pipes (synchronously reducing the number of distribution pipes connected with the distribution holes), or replacing the multi-way distribution pipe and the multi-way series pipe, without the need to modify or re-manufacture other parts of the distribution valve. Advantages

[0017] Simplify system structure: The existing analog continuous bed has numerous pipelines and complex connections, and the valve and controller form a "valve array". Although the mobile continuous bed reduces the number of connecting pipelines and valves, the reaction tower group needs to be gap-rotated on the track. The new high-efficiency distribution valve system can break through these limitations, greatly simplify the system structure of the entire continuous reaction tower group, no longer rely on complex "valve array", and no need for gap-rotated high-energy consumption on the track, reducing unnecessary equipment devices, and making the overall layout more compact and reasonable.

[0018] Reduce equipment investment and maintenance cost: The analog continuous bed has increased equipment investment, failure rate and maintenance rate due to the complex pipeline and valve system; the mobile continuous bed also has high equipment cost and operation and maintenance cost due to the large rotating parts and high energy consumption demand. The new system simplifies the structure, reduces the number of valves, controllers, large rotating drive equipment and foundation engineering, directly reducing the equipment investment cost. At the same time, the reduction of equipment number and the improvement of operation stability significantly reduce the failure rate and maintenance rate of the system, further saving the maintenance cost.

[0019] Improve operation stability and reliability: The analog continuous bed frequently switches valves, which is easy to cause failure; the mobile continuous bed needs to frequently start and stop due to the gap-rotated heavy reaction tower, affecting the operation stability. The new high-efficiency distribution valve system and its operation method avoid these unstable factors, ensure the stable conveying and distribution of materials in the production process through the innovative material distribution mode, reduce the mechanical wear and failure probability of the equipment, and greatly improve the operation stability and reliability of the continuous reaction tower group.

[0020] Reduce energy consumption: The mobile continuous bed rotates the reaction tower group and the rotating part at the same time when switching, and the large continuous bed even needs to drive nearly one thousand tons of weight, which has high energy consumption. The new system only needs to drive the upper and lower rotating discs to achieve the same distribution function, adopts more energy-saving material distribution and operation mechanism, greatly reduces the energy consumption while ensuring the smooth progress of the production process, meets the green production concept of sustainable development, and saves a large amount of energy cost for the enterprise.

[0021] Efficient operation: The upper and lower rotating discs are driven by the step reducer to rotate synchronously, and the rotating part realizes simple structure and light weight, the switching between different process states is rapid and stable, the downtime in the production process is reduced, and the production efficiency is improved. At the same time, the assembly structure of the distribution valve system is reasonably designed, easy to install and maintain, reduces the maintenance cost and downtime, and further improves the efficiency of production.

[0022] Accurate distribution: The unique valve body structure design, especially the precise setting of annular grooves, conversion hole groups and distribution hole groups on the fixed disc and rotating disc, can ensure accurate distribution of materials between the reaction towers, meeting the strict requirements of different processes for material flow and distribution sequence. Compared with traditional distribution valves, the accuracy of material distribution is greatly improved, reducing production problems caused by distribution errors, improving product quality and production efficiency.

[0023] High adaptability: It can flexibly adapt to the needs of continuous reaction tower groups in different fields and different production processes, including different numbers of reaction towers, various materials and complex process flows. By simply increasing the number of annular flow grooves and sealing ring sliding grooves on the fixed disc, the annular surface and conversion hole group and the sealing ring installation groove on the rotating disc, the treatment of various materials can be realized. By increasing the distribution hole, conversion hole and inlet and outlet flange pipe, the material distribution of the corresponding number of reaction towers can be realized.

[0024] Expand the application range of the process: The new high-efficiency distribution valve system breaks this limitation and can flexibly adapt to the different process needs of continuous reaction tower groups in various fields, especially providing the possibility for the widespread application of multi-stage series processes, so that enterprises can choose more diversified and optimized process flows according to actual needs in the production process, improving production efficiency and product quality.

The size, position, and number of the discharge flange pipe mounting hole group (46) of the annular sealing gasket sliding groove (45) on the lower fixed disc (8) are consistent with and uniformly distributed in the upper rotary disc (5).

[0233] As shown in Figure 10, the reverse side of the lower rotary disc (7) of the distribution valve device, according to process requirements, is assembled with an A material lower distribution pipe (82) to communicate an A material lower conversion hole C (193) in the A material conversion hole group with a lower distribution hole C (183), and an A material lower distribution pipe A (83) to communicate an A material lower conversion hole D (194) in the A material conversion hole group with a lower distribution hole D (184); the remaining A material lower conversion holes A (191), A material lower conversion hole B (192), A material lower conversion hole E (195), and A material lower conversion hole F (196) in the A material conversion hole group are closed with plugs (85) as standby holes for process adjustment. According to process requirements, a B material lower distribution pipe (84) is assembled to communicate a B material lower conversion hole F (206) in the B material conversion hole group with a lower distribution hole F (186), and the remaining B material conversion holes A (201), B material conversion hole B (202), B material conversion hole C (203), B material conversion hole D (204), and B material conversion hole E (205) are closed with plugs (85) as standby holes for process adjustment.

[0234] As shown in FIG. 2, FIG. 15, FIG. 16, FIG. 19, the rotating distribution mechanism is composed of the upper rotating disc (5) and the lower rotating disc (7) and the process pipeline and the attached fittings (6), the upper rotating disc (5) and the lower rotating disc (7) are in concentric position; the upper distribution hole A (121), the upper distribution hole B (122), the upper distribution hole C (123), the upper distribution hole D (124), the upper distribution hole E (125), the upper distribution hole F (126) of the upper rotating disc (5) and the lower distribution hole A (181), the lower distribution hole B (182), the lower distribution hole C (183), the lower distribution hole D (184), the lower distribution hole E (185), the lower distribution hole F (186) of the lower rotating disc (7) are respectively corresponding to the same center and the relative position remains unchanged in the rotating switching process.

[0235] As shown in FIG. 6, FIG. 7, FIG. 8, FIG. 9, FIG. 11, FIG. 14 and FIG. 19, after the lower valve body is assembled, the support spring installation slot (58) of the lower rotary disc (7) corresponds to the fixed disc support spring sliding groove (37), and the thrust ball bearing (54), support spring bracket (55) and support spring (56) are installed in the middle. The rotary disc water ring clamping groove (59) corresponds to the fixed disc water ring sliding groove (38), and the water ring (53) is installed in the middle. The lower rotary disc annular water collecting groove (60) corresponds to the fixed disc annular water collecting groove (39). The rotary disc sealing ring B installation slot (62) and rotary disc sealing ring A installation slot (63) correspond to the fixed disc sealing ring B sliding groove (41) and sealing ring A sliding groove (43) respectively, and the sealing ring B (52) and sealing ring A (51) are placed in the middle respectively. The rotary disc annular sealing gasket installation slot (64) corresponds to the fixed disc annular sealing gasket sliding groove (45), and the annular sealing gasket (50) is placed in the middle. The annular sealing gasket (50) is distributed with a through hole group consistent with the position, size and number of the rotary disc upper distribution hole group (65). The annular sealing gasket (50) is relatively fixedly installed in the rotary disc annular sealing gasket installation slot (64), so that the through hole group of the annular sealing gasket (50) and the rotary disc upper distribution hole group (65) always maintain one-to-one correspondence and communication. When rotating, the annular sealing gasket (50) rotates with the rotary disc, and slides in the fixed disc annular sealing gasket sliding groove (45). When staying in the working state, the distribution hole group (65) and the through hole group on the annular sealing gasket (50) are re-aligned at a new angle with the fixed disc discharge flange pipe installation hole group (46), that is, they maintain one-to-one correspondence and communication with the discharge flange pipe group (29).

[0236] Among them, the A material annular flow groove (44) of the lower fixed disc (8), the annular surface A (95) of the lower rotary disc (7), and the annular sealing gasket (50) and the sealing ring A (51) on both sides jointly constitute an A material annular flow chamber. In the A material annular flow chamber, the lower part of the chamber is communicated with the A material discharge main pipe (10) installed on the opposite side of the lower fixed disc (8) through the A material discharge main pipe installation hole (30) at the bottom of the A material annular flow groove (44) of the lower fixed disc (8), and the A material discharge main pipe installation hole A (31). The upper part of the chamber is connected with the corresponding lower distribution hole through the A material lower distribution pipe (82) and the A material lower distribution pipe A (83) on the opposite side of the lower rotary disc (7), and is further communicated with the corresponding lower flange pipe.

[0237] Similarly, the B material annular flow groove (42) of the lower fixed disc (8), the annular surface B (96) of the lower rotating disc (7), and the sealing ring A (51) and the sealing ring B (52) on both sides jointly constitute a B material annular flow chamber. In the B material annular flow chamber, the chamber lower surface is connected to the B material discharge header (12) installed on the opposite side of the lower fixed disc (8) through the B material discharge header installation hole (32) at the bottom of the B material annular flow groove (42), and is connected to the corresponding lower distribution hole through the B material lower distribution pipe (84) on the opposite side of the lower rotating disc (7) and further connected to the corresponding lower flange pipe.

[0238] As shown in FIG. 12, FIG. 13, the lower valve body drive shaft (16) is installed in the rotating disc shaft hole (57) of the lower rotating disc (7), and the cylindrical pin group (74) installed in the semicircular cross-section cylindrical pin slot group (75) on the drive shaft is respectively engaged into the cylindrical pin clamping slot group (68) on the inner surface of the rotating disc shaft hole (57), so that the lower rotating disc (7) can move axially along the lower valve body drive shaft (16) but cannot rotate relatively. The upper valve body drive shaft (15) is assembled in the upper rotating disc (5) in a similar manner.

[0239] As shown in FIG. 5, FIG. 6, FIG. 7, FIG. 8, and FIG. 14, the lower end of the lower valve body drive shaft (16) is axially fixedly installed in the shaft hole (36) of the lower fixed disc (8) through the front self-aligning thrust ball bearing (34) and the rear self-aligning thrust ball bearing (24), and the lower valve body drive shaft (16) can rotate relatively with the lower fixed disc (8) but cannot move axially. The upper valve body drive shaft (15) is assembled in the upper fixed disc (4) in a similar manner.

[0240] As shown in FIG. 1, FIG. 2, FIG. 15, and FIG. 20, after assembly is completed, the upper valve body drive shaft (15) and the lower valve body drive shaft (16) are connected through the coupling, and the upper rotating disc (5) and the lower rotating disc (7) rotate synchronously. The upper fixed disc (4) and the lower fixed disc (8) remain fixed.

[0241] As shown in FIG. 11, FIG. 14, FIG. 19, in the lower valve body (87) of the distribution valve device, after the lower rotary disc (7) and the lower fixed disc (8) are assembled, the compression degree of the compression spring (19) can be adjusted by the compression spring adjusting nut (21), and the tension degree of the support spring (56) can be adjusted by adjusting the support spring adjusting bolt set (88). By comprehensively adjusting the compression spring adjusting nut (21) and the support spring adjusting bolt set (88), the sealing degree and the rotary friction resistance of the sealing ring B (52), the sealing ring A (51), and the annular sealing washer (50) corresponding to the upper and lower matching surfaces between the lower rotary disc (7) and the lower fixed disc (8) can be adjusted. In the upper valve body, the support spring and the assembly are not installed, and the gravity action is applied to adjust the sealing degree with the compression spring adjusting nut.

[0242] As shown in FIG. 20, since the distribution valve device realizes the rotation of the valve body rotating mechanism and the fixation of the feeding part and the reaction tower group, it is convenient to realize the increase of the booster pump A (211), the booster pump B (212), the booster pump C (213), the booster pump D (214), the booster pump E (215), and the booster pump F (216) at the discharge end of each tower of the reaction tower group. Further, the booster pump can also be increased at the front end of each reaction tower, and the material of each tower is pressurized before feeding and after discharging, which is more conducive to the operation of the device.

[0243] Operation method implementation steps

[0244] The case is simplified for illustration, and only six reaction towers (such as the six reaction towers A (151), the reaction tower B (152), the reaction tower C (153), the reaction tower D (154), the reaction tower E (155), and the reaction tower F (156) in the present embodiment), two kinds of materials (such as A material and B material), and the corresponding series process are used as examples for illustration. The principles of more reaction towers and more material cases are the same, and are not described in detail.

[0245] As shown in FIG. 15, FIG. 16, when the distribution valve is assembled and running, starting from the initial state, the upper distribution holes A (121), B (122), C (123), D (124), E (125), F (126) are respectively aligned and communicated with the upper feed flange pipes A (131), B (132), C (133), D (134), E (135), F (136) one by one, and further communicated with the corresponding reaction tower feed ports A (141), B (142), C (143), D (144), E (145), F (146), while the lower distribution holes A (181), B (182), C (183), D (184), E (185), F (186) are respectively aligned and communicated with the lower discharge flange pipes A (171), B (172), C (173), D (174), E (175), F (176) one by one, and further communicated with the corresponding reaction tower lower discharge ports A (161), B (162), C (163), D (164), E (165), F (166); when the rotation is switched by 60 degrees, the upper distribution holes A (121), B (122), C (123), D (124), E (125), F (126) are respectively aligned and communicated with the upper feed flange pipes B (132), C (133), D (134), E (135), F (136), A (131) one by one, and further communicated with the corresponding reaction tower feed ports B (142), C (143), D (144), E (145), F (146), A (141),At the same time, the lower distribution holes A (181), B (182), C (183), D (184), E (185), and F (186) are in one-to-one alignment with the lower discharge flange pipes B (172), C (173), D (174), E (175), F (176), and A (171), and further communicate with the corresponding lower discharge ports B (162), C (163), D (164), E (165), F (166), and A (161) of the reaction towers. By analogy, after six rotation switching, i.e. rotation of 360 degrees, the corresponding situation is again in the starting state, and the cycle distribution of A and B materials is achieved. According to the above assembly and communication relationship, A and B materials from the A and B material feeding buffer tanks enter the A and B material feeding main pipes on the opposite side of the upper fixed disc (4), then pass through the A material annular flow channel (91) of the upper fixed disc, the B material annular flow channel (92) of the upper fixed disc, the A material upper distribution pipe (76), the A material upper distribution pipe A (77), the B material upper distribution pipe (78), and the corresponding distribution holes to reach the corresponding A and B material feeding flange pipes, and finally through the corresponding discharge flange pipes on the upper fixed disc (8), the corresponding distribution holes on the lower rotating disc (7), and the A material lower distribution pipe (82), the A material lower distribution pipe A (83), and the B material lower distribution pipe (84) to converge into the lower A and B material annular flow channels, and finally discharged from the overall device through the A material discharge main pipe (10) and the B material discharge main pipe (12).

[0250] Process operation in the starting stage: adjust the upper and lower rotating discs to the starting position, so that the distribution hole groups on the upper and lower rotating discs are respectively aligned with the feeding flange pipes and discharging flange pipes on the upper and lower fixed discs.

[0251] As shown in the process flow chart of Figure 21, the material feed pump is started, and the A material is fed from the A material feed buffer tank (89) through the pipeline into the A material feed main pipe (9) to the upper fixed disc A material annular flow channel (91) of the upper fixed disc. The A material is divided into two streams, one of which passes through the A material upper conversion hole A (111), the A material upper distribution pipe (76), the upper distribution hole A (121), the feed flange pipe A (131) to the reaction tower feed port A (141) of the 1# tower (151), and the other passes through the A material upper conversion hole B (112), the A material upper distribution pipe A (77), the upper distribution hole B (122), the feed flange pipe B (132) to the reaction tower feed port B (142) of the 2# tower (152). After the reaction is completed in the reaction tower, the material of the 1# tower (151) passes through the reaction tower lower discharge port A (161), the booster pump A (211), the discharge flange pipe A (171), the lower distribution hole A (181), the A material series pipe (79), the upper distribution hole D (124), the feed flange pipe D (134) to the reaction tower feed port D (144) of the 4# tower (154); the material of the 2# tower (152) passes through the reaction tower lower discharge port B (162), the booster pump B (212), the discharge flange pipe B (172), the lower distribution hole B (182), the A material series pipe A (80), the upper distribution hole C (123), the feed flange pipe C (133) to the reaction tower feed port C (143) of the 3# tower (153).

[0252] The flow path of the material is as follows: the B material is fed from the B material feeding buffer tank (90) through the pipeline into the B material feeding main pipe (11), and then into the upper fixed disc B material annular flow channel (92). The B material passes through the B material upper conversion hole E (105), the B material upper distribution pipe (78), the upper distribution hole E (125), the feeding flange pipe E (135), and then enters the reaction tower feeding port E (145) of the 5# tower (155).

[0253] Process operation after the first switching: after the initial stage reaction reaches the specified time, the first switching is performed, that is, the upper and lower rotating discs are synchronously rotated counterclockwise by 60 degrees, and after the switching, the second reaction stage is entered. The 6 upper distribution holes A (121), the upper distribution hole B (122), the upper distribution hole C (123), the upper distribution hole D (124), the upper distribution hole E (125), and the upper distribution hole F (126) on the upper rotating disc (5) are respectively aligned with the 6 feeding flange pipes B (132), the feeding flange pipe C (133), the feeding flange pipe D (134), the feeding flange pipe E (135), the feeding flange pipe F (136), and the feeding flange pipe A (131) on the upper fixed disc (4) one by one, that is, the 6 lower distribution holes A (181), the lower distribution hole B (182), the lower distribution hole C (183), the lower distribution hole D (184), the lower distribution hole E (185), and the lower distribution hole F (186) on the lower rotating disc (7) are respectively aligned with the 6 discharge flange pipes B (172), the discharge flange pipe C (173), the discharge flange pipe D (174), the discharge flange pipe E (175), the discharge flange pipe F (176), and the discharge flange pipe A (171) on the lower fixed disc (8) one by one, and the process state shown in FIG. 22 is entered. The operation is similar to the description of FIG. 21 and is not described in detail. The A material and the B material flow path diagram is as shown in FIG. 27 and FIG. 28.

[0254] Second switching process operation: after the initial stage reaction reaches the specified time, the second switching is performed, i.e. the upper and lower rotating discs are again synchronously rotated counterclockwise by 60 degrees, and after switching, the third reaction stage is entered, the six upper distribution holes A (121), the upper distribution hole B (122), the upper distribution hole C (123), the upper distribution hole D (124), the upper distribution hole E (125) and the upper distribution hole F (126) on the upper rotating disc (5) are respectively aligned with the six feeding flange pipes C (133), the feeding flange pipe D (134), the feeding flange pipe E (135), the feeding flange pipe F (136), the feeding flange pipe A (131) and the feeding flange pipe B (132) on the upper fixed disc (4) one by one, i.e. the six lower distribution holes A (181), the lower distribution hole B (182), the lower distribution hole C (183), the lower distribution hole D (184), the lower distribution hole E (185) and the lower distribution hole F (186) on the lower rotating disc (7) are respectively aligned with the six discharging flange pipes C (173), the discharging flange pipe D (174), the discharging flange pipe E (175), the discharging flange pipe F (176), the discharging flange pipe A (171) and the discharging flange pipe B (172) on the lower fixed disc (8) one by one, and the process state shown in FIG. 23 is entered. The description is similar to that of FIG. 21 and is not repeated. The A material, B material flow path diagram is shown in FIG. 29 and FIG. 30.

[0255] When the switching process is performed in sequence, after the sixth switching, the whole device returns to the initial stage process running state shown in Figure 21, that is, the six upper distribution holes A (121), the upper distribution hole B (122), the upper distribution hole C (123), the upper distribution hole D (124), the upper distribution hole E (125) and the upper distribution hole F (126) on the upper rotating disc (5) are respectively aligned with the six feeding flange pipes A (131), the feeding flange pipe B (132), the feeding flange pipe C (133), the feeding flange pipe D (134), the feeding flange pipe E (135) and the feeding flange pipe F (136) on the upper fixed disc (4) one by one, and the six lower distribution holes A (181), the lower distribution hole B (182), the lower distribution hole C (183), the lower distribution hole D (184), the lower distribution hole E (185) and the lower distribution hole F (186) on the lower rotating disc (7) are respectively aligned with the six discharging flange pipes A (171), the discharging flange pipe B (172), the discharging flange pipe C (173), the discharging flange pipe D (174), the discharging flange pipe E (175) and the discharging flange pipe F (176) on the lower fixed disc (8) one by one. After the reaction is completed, the switching is continued, and the whole device enters the cycle running similar to the description in Figure 21.

[0256] The above embodiment only describes the processing of A and B materials, mainly to make the description simple and clear. The distribution valve device is not only suitable for the processing of two materials in this example, but also can be expanded to multiple materials according to actual needs. When multiple materials need to be processed, the number of annular flow grooves and the corresponding conversion holes on the front surface of the upper and lower fixed discs is increased by the same number as the number of materials, and the middle is separated by a sealing ring sliding groove, and the corresponding annular surface, sealing ring installation groove and conversion hole group are added to the front surface of the upper and lower rotating discs, so that the simultaneous processing of multiple materials can be realized.

[0257] The material discharging direction in the multi-fluid material continuous circulation distribution valve device is not limited to the upper inlet and lower outlet mode, and the feeding and discharging directions can be adjusted according to the process requirements. The A material feeding main pipe (9) and the B material feeding main pipe (11) are used as discharging main pipes, and the A material discharging main pipe (10) and the B material discharging main pipe (12) are used as feeding main pipes, so that the A and B materials or one of the materials can be conveniently changed in the feeding and discharging directions without modifying other devices and parts.

[0258] In the multi-fluid material continuous circulation distribution valve device, Figure 31The shown is one of the examples of the continuous bed system composed of the six reaction towers for processing two kinds of materials. According to the principle of the continuous rotary distribution valve, the same process requirements in the reaction tower group can also be achieved. Therefore, in addition to the processes listed in this specification, by adjusting the position of the upper and lower distribution holes connected by the series pipes, increasing the number of series pipes (synchronously reducing the number of connections between the distribution pipes and the distribution holes), or replacing the multi-way distribution pipes and multi-way series pipes, a variety of series and parallel reaction processes can be easily adjusted without modifying or remanufacturing other parts of the distribution valve. Other processes are not listed one by one.

[0259] The continuous bed system composed of the continuous circulation distribution valve device of the multi-fluid material is not limited to the case of six reaction towers listed in this specification. It only needs to match the same number of conversion holes on each annular surface of the upper and lower rotary discs, match the same number of distribution holes at the bottom of the annular sealing washer sliding groove, match the same number of corresponding through holes on the annular sealing washer, and match the same number of inlet and outlet flange pipe mounting holes and inlet and outlet flange pipes on the fixed disc, and uniformly distribute, so as to achieve the purpose of material distribution for the corresponding number of reaction towers.

[0260] The continuous bed system composed of the continuous circulation distribution valve device of the multi-fluid material is not limited to the case of distributing two kinds of materials listed in this specification. According to the actual number of material types that need to be distributed, match the same number of annular flow channels and corresponding sealing ring sliding grooves on the front surface of the fixed disc, set the same number of material inlet and outlet main pipes to communicate with them, and at the same time match the same number of annular surfaces and corresponding sealing ring mounting grooves on the rotary disc. After cooperation, the same number of annular flow chambers are formed, which can process and distribute the actual number of material types required.

[0261] Therefore, the number of material types that can be distributed is related to the number of annular flow channels and material inlet and outlet main pipes on the fixed disc, the number of annular surfaces on the rotary disc, etc., and is not related to the number of reaction towers. The number of reaction towers is related to the number of conversion holes and distribution holes at the bottom of each annular flow channel on the fixed disc, and the number of inlet and outlet flange pipes assembled on the fixed disc, and is the same, and is not related to the number of annular flow channels, that is, the number of material types that need to be distributed.
