| titleOfInvention | 1, 3-cyclohexanedione membrane filtration refining equipment |
| abstract | The utility model provides 1, 3-cyclohexanedione membrane filtering and refining equipment, which belongs to the technical field of filtering equipment and comprises a raw material tank, a primary circulating unit, a ceramic membrane filter, a secondary circulating unit, a nanofiltration membrane filter and a storage tank; the raw material tank is communicated with the ceramic membrane filter through the primary circulating unit, the ceramic membrane filter is communicated with the nanofiltration membrane filter through the secondary circulating unit, and the nanofiltration membrane filter is communicated with the storage tank. According to the utility model, the combination of the ceramic filtering membrane and the nano filtering membrane is used, so that macromolecular pigments and other insoluble particles in the 1, 3-cyclohexanedione intermediate solution can be removed, and a pure white product with crystal luster can be obtained after acidification and crystallization, is not easy to discolor in the storage and transportation links, can reach the quality standard of a medical intermediate, and has high purity. |
