| titleOfInvention | A kind of purification equipment of 1,4-butanediol |
| abstract | The utility model provides a purification equipment for 1,4-butanediol, which comprises a BDO raw material storage tank, a first feed pump, a single-bed ion exchange column, a mixed-bed ion exchange column, a buffer tank and a vacuum dehydration kettle, which are connected in sequence. , feed pump, filter device and storage tank. The utility model uses the common ion impurity removal effect of the single-bed ion exchange column and the mixed-bed ion exchange column, and cooperates with the multi-stage high-precision filtration effect of the upper filter device, on the premise of ensuring that the purity of BDO does not decrease, and reduces the various impurities in BDO. Metal cation impurities, at the same time remove common anion impurities, control and reduce impurity particles above 0.2um, and further improve the product quality of BDO. |
