一种古龙酸高倍浓缩生产方法及设备
摘要：
本发明公开了一种古龙酸高倍浓缩生产方法，将树脂离子交换液或者传统纳滤设备浓缩液通过输料泵输送至精密过滤器内；经过精密过滤器后的料液进入增压泵，增压泵将料液压力提升至50-70bar；料液再进入在线增压泵，在线增压泵混合高倍浓缩膜出口的部分浓缩液和经过增压泵加压的料液，将压力进一步提升至55-75bar；料液然后进入高倍浓缩膜内部进行分离，在高压的驱动下，料液中的水透过膜组件进入透析液管路，浓缩液部分外排，部分回流至在线增压泵入口。本发明还公开了相应的生产设备。本发明可以将古龙酸浓度提高至更高的浓度，降低蒸发器的投资成本、降低能耗和提高产品品质，节能90%。
摘要（英）：

The invention discloses a production method and apparatus for high-power concentration of gulonic acid, which comprises delivering a resin ion-exchanged solution or concentrate from a conventional nanofilter to a precise filter through a delivery pump; delivering the material solution to a booster pump, and boosting a pressure to 50-70 bar; delivering the material solution to an online booster pump, mixing a part of concentrate from the outlet of a high-power concentration membrane and the material solution, and boosting the pressure to 55-75 bar; and separating the mixture through the high-power concentration membrane, driving water in the mixture under the high pressure to penetrate a membrane component to enter a dialysate pipe, discharging a part of the concentrated solution, and returning the rest of the concentrated solution to the inlet of the online booster pump. The invention also discloses a production apparatus for high-power concentration of gulonic acid. The invention can increase the concentration of gulonic acid to a higher level, reduce the investment cost of an evaporator, lower energy consumption by 90%, and improve the product quality.
