Title:
CONTINUOUS CRYSTAL TRANSFORMATION AND ION EXCHANGE DEVICE AND PROCESS
Document Type and Number:
WIPO Patent Application WO/2022/121223
Kind Code:
A1
Abstract:
A continuous crystal transformation and ion exchange device and process, relating to the technical field of molecular sieve manufacturing. The continuous crystal transformation and ion exchange device comprises M + N reaction tanks which are in serial connection, wherein a feed opening of a following reaction tank is in communication with a discharge opening of a preceding reaction tank by means of a reaction solution circulation pipeline, and a discharge opening of the M + N th reaction tank is in communication with a feed opening of the first reaction tank by means of the reaction solution circulation pipeline. No more than M reaction tanks are used for the crystal transformation process, and no more than N reaction tanks are used for the ion exchange process. The method is used for preparing a finished zeolite molecular sieve product, and has the advantages of high exchange capacity, simple process, low cost and the like.
