Embodiment

[0043] Such as figure 1 As shown, a high-purity octahydrate barium hydroxide purification production system includes a raw material warehouse, a mother liquor tank, a dissolution tank, a precision filter, a transfer tank, a DTB crystallization system, a thickener, a centrifugal separator, and a drying machines, jet crushers and automatic packaging machines. Among them, the raw material warehouse and the dissolution tank are connected by a metering belt, and the mother liquor tank, dissolution tank, precision filter, transfer tank, DTB crystallization system, thickener, centrifugal separator, dryer, air flow crusher and automatic packaging machine pass through the pipeline. Connected in turn, the pipelines are equipped with pump bodies and valves for controlling the normal transportation of materials. In this embodiment, the outer sides of the pipelines are equipped with insulation layers to keep the transported slurry warm and prevent crystals from being precipitated in the pi...

Abstract

The invention discloses a high-purity barium hydroxide octahydrate purification production system and method, and belongs to the technical field of barium hydroxide octahydrate purification. The system comprises a raw material bin, a mother liquor tank, a dissolving tank, a precision filter, a transfer tank, a DTB crystallization system, a thickener, a centrifugal separator, a dryer, an airflow crusher and an automatic packaging machine which are communicated in sequence. The whole processing process is continuous, and the production process is completed in a closed system, so that the whole operation process is safer while the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of barium hydroxide octahydrate purification, in particular to a high-purity barium hydroxide octahydrate purification production system and method. Background technique [0002] Barium Hydroxide Octahydrate Ba(OH) 2 .8H 2 O is an important raw material for chemical production, mostly used in chemical industry, light industry, medicine and other industries, such as multi-functional additives in the petroleum industry, barium-based grease and oil refining, stabilizers for the production of plastics, etc. Among them, high-quality barium hydroxide octahydrate is mainly used in the production of high-purity barium titanate by hydrothermal method and experimental purposes. [0003] The conventional production process of high-quality pure barium hydroxide octahydrate is usually only physical filtration, lacking the means of removing soluble ions, and the product purity is not high. Single-tank intermittent oper...
