introduction

        The DTB type crystallizer is a typical crystal slurry internal circulation crystallizer. Because the internal guide tube is set in the crystallizer, the circulation channel is formed, so that the crystal slurry has good mixing conditions. Only a very low pressure head is needed to make the crystal slurry. Realize a good internal circulation inside.

        In evaporative crystallization, the supersaturation at the boiling interface can be quickly eliminated, and the supersaturation of the solution can be at a relatively low level. It is especially suitable for products with a steep solubility curve. It has been proved by practice that the DTB crystallizer has good performance and production High strength, can produce larger grains, and it is not easy to scar in the crystallizer. It has become one of the main forms of continuous crystallizer. It can be applied to the crystallization operation of vacuum cooling method, evaporation method, direct contact freezing method and reaction method.

Applicable products: potassium chloride, iminodiacetonitrile. Reflects ammonium sulfate, ammonium chloride, etc.
