Description
Technical Field
[0001] The invention relates to the technical field of particle material production devices, and in particular to a structure for uniformly extracting gas from a filling-type particle material processing device. Background Art
[0002] In some filled particulate material processing equipment, such as slice drying, slice solid phase thickening and other equipment, there is often a problem of needing to export the gas medium entering from the lower section of the equipment from the middle section of the equipment. The method commonly used at present is to set an inner cone at the position where the gas medium needs to be exported from the reactor, and form a cavity without granular materials between the inner cone and the equipment cylinder. A hole is opened on the equipment cylinder wall at the cavity to set a nozzle to export the gas medium. Although this structure can realize the export of gas from the middle section of the equipment, since there is no gas export device at the center of the equipment, it often leads to uneven flow of gas medium between solid particle beds near the gas export position. When the diameter of the equipment is relatively large, this unevenness will be more serious. For gas flow path, please refer to Figure 1 As shown, a structure is needed to ensure uniform airflow conduction. Summary of the invention

[0019] In order to make the technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention:
[0020] like Figure 2 A structure for uniformly exporting gas from a filled particulate material processing device is shown, and the structure is used for filled particulate material processing equipment, such as slice drying, slice solid phase viscosity enhancement and other equipment. Filled particulate material processing equipment often uses gas medium as a carrier to process materials, for example, the slice drying system uses gas as a drying medium, the slice solid phase viscosity enhancement system uses gas medium to remove low molecular weight substances generated by the reaction, and so on. In these processes, as the output increases, the monomer equipment becomes larger and larger. If the traditional gas operation method is still used, the total pressure drop of the gas medium passing through the processing equipment will continue to increase, resulting in increased operating energy consumption. In order to solve the problem of increased pressure drop and increased energy consumption, it can be solved by exporting part of the gas medium from the middle section of the equipment. The present invention discloses a special structure, which can evenly export gas from the middle section of the equipment. The specific scheme is as follows: it includes an equipment cylinder 1, an inner cone 2 connected to the inner wall of the equipment cylinder 1, an inverted cone 3 at the center of the equipment cylinder 1, a connecting pipe 5 connecting the inverted cone 3 and the inner cone 2, and a gas outlet nozzle 4. The connection method is: the inner wall of the equipment cylinder 1 is connected to the inner cone 2, the inverted cone 3 is arranged at the center of the equipment cylinder 1, the inverted cone 3 is connected to the inner cone 2 through the connecting pipe 5, and the gas outlet nozzle 4 is connected to the outer wall of the equipment cylinder 1.
[0021] Further, as shown in Figures 3 and Figure 4As shown, the cone angle 32 between the inner cone 2 and the inverted cone 3 can be adjusted between 20 and 90° as needed. The angle is determined by the flow properties of the granular material. The cone angle 32 can be larger, closer to 90°, when the flow is good, and smaller, closer to 20°, when the flow is poor. The connecting pipe 5 connecting the inverted cone 3 and the inner cone 2 can be a round tube, a square tube or other polygonal tubes. Two guide baffles 51 are arranged on the top of the connecting pipe 5. The angle 52 between the two guide baffles 51 can be adjusted between 20 and 90° as needed. The purpose of the guide baffle 51 is to prevent the granular material from stagnating locally due to the presence of a platform above the connecting pipe 5. The angle selection principle between the two guide baffles 51 is the same as the cone angle. When the connecting pipe 5 adopts a polygonal tube, the guide baffles 51 can be used as the two edges of the top of the polygonal tube, which can simplify the equipment structure and save materials.
[0022] Furthermore, a set of inner cone 2 and inverted cone 3 structures is usually provided. When a set of inner cone 2 and inverted cone 3 structures is provided, the bottom diameter of inner cone 2 and inverted cone 3 is 0.5 to 0.75 times the inner wall diameter of equipment barrel 1, and the distance between the bottom edge of inner cone 2 and the bottom edge of inverted cone 3 should be determined according to the flow rate of particulate material. When the equipment diameter is large, two or even more sets of inner cone 2 and inverted cone 3 structures can be provided. Using multiple sets of inner cone 2 and inverted cone 3 structures can reduce the structural height of the gas outlet structure and further increase the uniformity of gas flow.
[0023] Furthermore, one or more connecting pipes 5 connecting the inverted cone 3 and the inner cone 2 can be provided as required, and the cross-sectional area of the connecting pipe 5 is determined according to the amount of gas discharged. When multiple connecting pipes 5 are used, the connecting pipes are evenly distributed along the circumferential direction. When multiple sets of inner cones 2 and inverted cones 3 are used, the connecting pipes 5 should connect all cones.
[0024] Furthermore, when multiple groups of inner cones 2 and inverted cones 3 are used, the inner cones 2 and inverted cones 3 are arranged in a manner of equally dividing the areas.
[0025] Furthermore, one or more gas medium outlet nozzles 4 may be provided.
[0026] Furthermore, a gas cavity 23 without granular material filling is formed between the inner cone 2 and the cylinder wall and below the inverted cone 3. The gas medium accumulates in the cavity and is then discharged through the connecting pipe 5 and the gas medium outlet nozzle 4. The cavity volume and the cone bottom area are set according to process requirements to ensure uniform discharge of the gas medium.
[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
