Description

Technical Field

[0001] The utility model belongs to the technical field of fluidized reactors, and particularly relates to a fluidized reactor for aluminum fluoride. Background Technique

[0002] Aluminum fluoride is an inorganic compound. It is a white crystal, insoluble in water, acids and alkalis. Aluminum fluoride can decompose at high temperatures, releasing hydrogen fluoride gas. It is mainly used for preparing other aluminum fluorides, as well as components such as catalysts, fluxes and glazes. The fluidization of aluminum fluoride usually involves dispersing it into fine particles in an inert gas or liquid and keeping it suspended by a flowing gas or liquid.

[0003] The commonly used fluidized reactor for aluminum fluoride, when in use, installs an aeration device at the bottom end of one side of the reactor. During operation, the gas ejected by the aeration device drives the aluminum fluoride suspension upward from the bottom end of one side of the reactor, and then the aluminum fluoride suspension flows downward from the other side of the reactor, thus forming a cycle. Since aeration is only carried out on one side, the flow rate of the aluminum fluoride suspension is relatively slow, especially the aluminum fluoride suspension in the middle of the reactor, which is in the central part of the cycle and its flow rate is restricted. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fluidized reactor for aluminum fluoride, which circulates the aluminum fluoride solution around the bottom of the upwelling channel during operation, improves the flow rate, and further improves the reaction efficiency, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A fluidized reactor for aluminum fluoride, including a housing and a partitioning component. The partitioning component is fixedly connected to the middle part inside the housing. The partitioning component includes a cylinder, and the bottom of the cylinder is provided with uniformly distributed through holes. The partitioning component divides the interior of the housing into an upwelling channel and a downflow channel. The upwelling channel and the downflow channel are communicated through the through holes. The bottom end of the upwelling channel is provided with an annular fluidization component, and the bottom of the housing is provided with an air inlet component for supplying gas to the fluidization component.

[0006] Further, the bottom end of the housing is fixedly connected with equally spaced support legs.

[0007] Further, the top of the inner wall of the cylinder is provided with internal threads, and a lifting cylinder is arranged inside the cylinder. The outer wall of the lifting cylinder is provided with external threads that cooperate with the internal threads. The top end of the lifting cylinder is symmetrically provided with convex plates.

[0008] Further, a limiting ring is fixedly connected to the inner wall of the cylinder, and the longitudinal section of the limiting ring is triangular.

[0009] Further, the fluidization component includes an annular pipe fixedly connected to the bottom end of the upwelling channel, and the top end of the annular pipe is fixedly communicated with air outlet heads that are equidistantly distributed around the axis of the annular pipe.

[0010] Further, the air intake component includes a disc, and the top end of the disc is fixedly communicated with connecting pipes that are equidistantly distributed around the axis of the disc. The top ends of the connecting pipes are fixedly communicated with the bottom of the annular pipe.

[0011] Further, the bottom end of the disc is fixedly communicated with an air inlet pipe, and one end of the air inlet pipe is communicated with an external air source.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The air intake component supplies air evenly to the inside of the fluidization component, and the air is discharged from the periphery of the bottom of the upwelling channel through the fluidization component, thereby driving the aluminum fluoride suspension around the bottom of the upwelling channel to flow upward. The aluminum fluoride suspension in the upper part flows downward through the opening at the top of the separation component, and the aluminum fluoride suspension flowing to the bottom flows out through the through hole, thus forming a cycle. The aluminum fluoride solution circulates from the periphery of the bottom of the upwelling channel, increasing the flow rate and thereby improving the reaction efficiency.

Detailed Embodiments

[0018] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0019] Such as Figure 1 and 3As shown in the figure, a fluidized bed reactor for aluminum fluoride includes a housing 1 and a partition component 2. The bottom end of the housing 1 is fixedly connected with evenly distributed support legs 11. The partition component 2 is fixedly connected to the middle part inside the housing 1. The partition component 2 includes a cylinder 21. The bottom of the cylinder 21 is provided with evenly distributed through holes 22. The partition component 2 divides the interior of the housing 1 into an upwelling channel 12 and a downflow channel 13. The upwelling channel 12 and the downflow channel 13 are communicated through the through holes 22. The bottom end of the upwelling channel 12 is provided with an annular fluidization component 4. The bottom of the housing 1 is provided with an air inlet component 3 for supplying gas to the fluidization component 4.

[0020] According to the above structure, when in use, gas is evenly supplied to the inside of the fluidization component 4 through the air inlet component 3. The air is discharged from the periphery of the bottom of the upwelling channel 12 through the fluidization component 4, thereby driving the aluminum fluoride suspension around the bottom of the upwelling channel 12 to flow upward. The upper aluminum fluoride suspension flows downward through the opening at the top of the partition component 2. The aluminum fluoride suspension flowing to the bottom flows out through the through holes 22, thus forming a cycle. The aluminum fluoride solution circulates from the periphery of the bottom of the upwelling channel 12, increasing the flow rate and thereby improving the reaction efficiency.

[0021] As Figure 3 shown, the top of the inner wall of the cylinder 21 is provided with an internal thread 23. An elevating cylinder 24 is arranged inside the cylinder 21. The outer wall of the elevating cylinder 24 is provided with an external thread 25 that matches the internal thread 23. The top of the elevating cylinder 24 is symmetrically provided with convex plates 26.

[0022] According to the above structure, during actual use, the height of the partition component 2 can be adjusted according to the amount of the aluminum fluoride suspension, improving the practicality. During adjustment, the elevating cylinder 24 is rotated through the two convex plates 26 to adjust the height of the elevating cylinder 24, and thus the height of the entire partition component 2 is adjusted.

[0023] As Figure 3 shown, a limiting ring 27 is fixedly connected to the inner wall of the cylinder 21. The longitudinal section of the limiting ring 27 is triangular.

[0024] According to the above structure, the limiting ring 27 plays the role of preventing the excessive downward movement of the elevating cylinder 24, avoiding blocking the through holes 22. The cross section of the limiting ring 27 is triangular, thus preventing the accumulation of aluminum fluoride at the top of the limiting ring 27.

[0025] As Figure 2 and 3As shown in the figure, the fluidization component 4 includes an annular pipe 41 fixedly connected to the bottom end of the upwelling channel 12. The top end of the annular pipe 41 is fixedly communicated with air outlet heads 42 that are equidistantly distributed around the axis of the annular pipe 41. The air inlet component 3 includes a disc 31. The top end of the disc 31 is fixedly communicated with connecting pipes 33 that are equidistantly distributed around the axis of the disc 31. The top ends of the connecting pipes 33 are fixedly communicated with the bottom of the annular pipe 41. The bottom end of the disc 31 is fixedly communicated with an air inlet pipe 32, and one end of the air inlet pipe 32 is communicated with an external air source.

[0026] According to the above structure, when supplying air, air is supplied into the interior of the disc 31 through the air inlet pipe 32. The air inside the air inlet pipe 32 can uniformly enter the interiors of several connecting pipes 33. The several connecting pipes 33 uniformly send the air into the interior of the annular pipe 41. The air inside the annular pipe 41 is discharged through several air outlet heads 42, thereby uniformly driving the aluminum fluoride suspension at the bottom of the upwelling channel 12 to flow upward.

[0027] The working principle of the present utility model is as follows: When supplying air, air is supplied into the interior of the disc 31 through the air inlet pipe 32. The air inside the air inlet pipe 32 can uniformly enter the interiors of several connecting pipes 33. The several connecting pipes 33 uniformly send the air into the interior of the annular pipe 41. The air inside the annular pipe 41 is discharged through several air outlet heads 42, thereby uniformly driving the aluminum fluoride suspension at the bottom of the upwelling channel 12 to flow upward. The upper aluminum fluoride suspension flows downward through the opening at the top of the partition component 2. The aluminum fluoride suspension flowing to the bottom flows out through the through hole 22, thus forming a circulation. The aluminum fluoride solution circulates from the periphery of the bottom of the upwelling channel 12, increasing the flow rate, and thus improving the reaction efficiency. During actual use, the height of the partition component 2 can be adjusted according to the amount of the aluminum fluoride suspension, improving the practicability. During adjustment, the height of the lifting cylinder 24 is adjusted by rotating the lifting cylinder 24 through two convex plates 26, and thus the height of the entire partition component 2 is adjusted. The limiting ring 27 serves to prevent the lifting cylinder 24 from moving downward excessively, avoiding blocking the through hole 22. The cross-section of the limiting ring 27 is triangular, thereby preventing the accumulation of aluminum fluoride at the top of the limiting ring 27.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
