[0030] As Figure 1 shown, the present utility model provides a spherical molecular sieve dynamic exchange device, including an exchange tank 1. A perforated inclined plate 11 is arranged in the exchange tank 1. The inclined plate 11 divides the interior of the exchange tank 1 into two parts. The upper space of the inclined plate 11 is an exchange area 12, and the lower space of the inclined plate 11 is an accommodation area 13. The spherical molecular sieve is arranged in the exchange area 12. The size of the holes on the inclined plate 11 is smaller than the size of the spherical molecular sieve. The spherical molecular sieve covers the upper surface of the inclined plate 11. The inclined plate 11 is used to isolate the spherical molecular sieve from the bottom of the exchange tank 1 to prevent the spherical molecular sieve from blocking at the bottom of the exchange tank 1. After the exchange liquid is exchanged, it flows out from the holes of the inclined plate 11 and enters the accommodation area 13. The exchange area 12 communicates with the liquid inlet end of the exchange tank 1, and the accommodation area 13 communicates with the liquid outlet end of the exchange tank. Both the exchange area 12 and the accommodation area 13 have a certain space to play a buffering role. When the flow rate of the exchange liquid is large, the exchange area 12 can prevent the exchange liquid from overflowing and flowing back, and the accommodation area 13 can prevent the exchange waste liquid from overflowing and flowing back.

The discharge port 14 is located near the lowest end of the inclined plate 11. The discharge port 14 is the feed port for the spherical molecular sieve. The spherical molecular sieve enters the exchange tank 1 through the discharge port 14 and is laid flat and stacked on the inclined plate 11. The inclination angle of the inclined plate 11 is controlled to ensure that the spherical molecular sieve can be laid flat on the inclined plate 11.
[0032] As shown Figure 1 in Figure, the liquid outlet end of the exchange tank 1 is communicated with the liquid inlet end of valve B15. The liquid outlet end of valve B15 is communicated with the liquid inlet end of circulation pump 16. The liquid outlet end of circulation pump 16 is communicated with the liquid inlet end of valve C17. The liquid outlet end of valve C17 is communicated with the liquid inlet end of the exchange tank 1. Valve B15, circulation pump 16, valve C17 and the connected pipelines form an exchange liquid circulation channel, and the exchange liquid of the same batch can be subjected to multiple exchange treatments.
[0033] As shown Figure 1 in Figure, the present utility model further includes a pre-exchange storage tank 2. The pre-exchange storage tank 2 is communicated with the exchange tank 1 inside the exchange tank 1. The pre-exchange storage tank 2 can store the intermediate products of the exchange liquid exchange. These intermediate products can be used for the exchange treatment of other batches. In a preferred embodiment, the liquid outlet end of the circulation pump 16 is further communicated with the liquid inlet end of valve D21. The liquid outlet end of valve D21 is communicated with the liquid inlet end of the pre-exchange storage tank 2. The liquid outlet end of the pre-exchange storage tank 2 is communicated with the liquid inlet end of valve F22. The liquid outlet end of valve F22 is communicated with the liquid inlet end of the exchange tank 1, forming a circulation path between the exchange tank 1 and the pre-exchange storage tank 2.
[0034] As shown Figure 1 in Figure, the present utility model further includes an exchange liquid preparation tank 3. The exchange liquid preparation tank 3 is used for preparing the exchange liquid. Specifically, the raw powder and deionized water are simultaneously put into the exchange liquid preparation tank 3 according to a ratio to obtain the exchange liquid. In a preferred embodiment, the liquid outlet end of the exchange liquid preparation tank 3 is communicated with the liquid inlet end of valve A31. The liquid outlet end of valve A31 is communicated with the liquid inlet end of the exchange tank 1.
[0035] As shown Figure 1 in Figure, the present utility model further includes a waste liquid storage tank 4. The liquid outlet end of the circulation pump 16 is communicated with the liquid inlet end of valve E41. The liquid outlet end of valve E41 is communicated with the liquid inlet end of the waste liquid storage tank 4. A drain valve is further provided at the bottom of the waste liquid storage tank 4. Opening the drain valve can release the solution in the waste liquid storage tank 4.
[0036] As shown Figure 1As shown, a first stirring device 23 is provided in the pre-exchange storage tank 2, a second stirring device 32 is provided in the exchange liquid preparation tank 3, and a third stirring device 42 is provided in the waste liquid storage tank 4.
[0037] As Figure 2 shown, the holes on the inclined plate 11 are round holes.
[0038] The working process of the present utility model is as follows:
[0039] I. Preparation of exchange liquid
[0040] Close the valve A31, add the original powder and deionized water to the exchange liquid preparation tank 3 in proportion, and at the same time start the second stirring device 32. After all the original powder is dissolved and stirred evenly, turn off the second stirring device 32.
[0041] II. Exchange process
[0042] 1. Single exchange: Open the valve A31, the valve B15 and the valve E41, start the circulation pump 16. The exchange liquid enters the exchange tank 1 from the exchange liquid preparation tank 3. After passing through the spherical molecular sieve, the exchange liquid falls into the accommodation area 13, and successively passes through the valve B15, the circulation pump 16 and the valve E41, and finally enters the waste liquid storage tank 4 for storage;
[0043] 2. Circulating exchange: First, open the valve A31, the valve B15 and the valve C17, start the circulation pump 16. The exchange liquid enters the exchange tank 1 from the exchange liquid preparation tank 3. After passing through the spherical molecular sieve, the exchange liquid falls into the accommodation area 13, and successively passes through the valve B15, the circulation pump 16 and the valve C17 and then enters the exchange tank 1 again for exchange. Until the number of circulation times reaches the preset value, then close the valve C17 and open the valve E41 to let the exchanged waste liquid enter the waste liquid storage tank 4 for storage;
[0044] 3. Pre-exchange: Open the valve A31, the valve B15 and the valve D21, start the circulation pump 16. The exchange liquid enters the exchange tank 1 from the exchange liquid preparation tank 3. After passing through the spherical molecular sieve, the exchange liquid falls into the accommodation area 13, and successively passes through the valve B15, the circulation pump 16 and the valve D21 and then enters the pre-exchange storage tank 2. When the intermediate product in the pre-exchange storage 2 needs to be exchanged again, open the valve F22, and the intermediate product will enter the exchange tank 1 again. The operation of temporarily storing after exchange can be combined with the above single exchange or circulating exchange process. The solution in the pre-exchange storage tank 2 can also be the prepared exchange liquid.
[0045] III. Cleaning after exchange
[0046] After the exchange is completed, deionized water is added to the part that needs to be cleaned. For example, if it is necessary to clean the inside of the exchange tank 1 and the spherical molecular sieve, deionized water is added to the inside of the exchange tank 1 from the liquid inlet end of the exchange tank 1, and the deionized water is circulated in the exchange tank 1 according to the above cyclic exchange process. For other parts, the stirring device is directly started to drive the deionized water to move to accelerate the cleaning.
[0047] IV. Post-treatment after exchange
[0048] Open the discharge port 14 to discharge the exchanged spherical molecular sieve, and the obtained spherical molecular sieve is dried and calcined. The waste water after cleaning and the exchange waste liquid are regularly treated and then discharged.
[0049] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
