Description

Technical Field

[0001] The invention relates to the technical field of crystallization production devices, and in particular to a production device and method for trimethylamine oxide. Background Art

[0002] As a natural and safe feed additive, trimethylamine oxide has broad development prospects in animal husbandry. The aqueous solution of trimethylamine is oxidized by hydrogen peroxide to obtain an aqueous solution of trimethylamine oxide, which is then concentrated and crystallized to obtain dihydrated trimethylamine oxide. The dihydrated trimethylamine oxide is heated in a medium-high temperature solvent for dehydration and crystallization, or vacuum drying and dehydration, spray drying and dehydration, to obtain anhydrous trimethylamine oxide. The existing dehydration and oxidation process is mainly achieved by an evaporation crystallizer, but the existing evaporation crystallizer still has some problems during use, as follows:

[0003] The current evaporation crystallizer mainly reduces the pressure of the high-temperature liquid generated in the heating chamber and evaporates and crystallizes it, so that water is discharged from the top, and the solute therein is crystallized and precipitated. However, the internal structure of the existing evaporation crystallizer is too simple, and it simply uses a sealed container to evacuate and reduce the pressure, so that the solute in the solution precipitates when the water evaporates after the pressure is reduced. It is very inconvenient to remove and separate the solute precipitated at the bottom of the container, and the particle size of the precipitated solute cannot be effectively controlled, which easily causes the precipitated solute to aggregate at the bottom of the container for a long time to form large crystal blocks, resulting in inconvenience in subsequent use. For this reason, we propose a production device and method for trimethylamine oxide. Summary of the invention
