一种半纤维素连续水解制备木糖液的系统
摘要：
本实用新型涉及一种半纤维素连续水解制备木糖液的系统，包括中和单元、调酸单元、进料单元、液化喷射单元、进出料换热单元、出料控制单元。中和单元包括原料罐、中和浓硫酸泵、中和管道混合器，调酸单元包括调酸浓硫酸泵、调酸管道混合器和调酸罐，进料单元包括进料罐，液化喷射单元包括液化喷射器和液化维持器，进出料换热单元包括进出料板式换热器和第一出料温度传感器，出料控制单元包括出料阀和回流阀。制备的木糖液在进出料板式换热器中与半纤维素液进行换热，使得木糖液的温度降低，而半纤维素液的温度升高。本实用新型同时进料和出料换热，能够大大降低能耗，且连续进出料，提高生产效率，简化了工人操作。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model relates to a system for preparing xylose liquid by continuously hydrolyzing hemicellulose. The system comprises a neutralizing unit, an acid adjusting unit, a feeding unit, a liquefaction spraying unit, a feeding and discharging heat exchange unit and a discharging control unit. The neutralizing unit comprises a raw material tank, a neutralizing concentrated sulfuric acid pump and a neutralizing pipeline mixer; wherein the acid adjusting unit comprises an acid adjusting concentrated sulfuric acid pump, an acid adjusting pipeline mixer and an acid adjusting tank, the feeding unit comprises a feeding tank, the liquefaction spraying unit comprises a liquefaction sprayer and a liquefaction maintainer, the feeding and discharging heat exchange unit comprises a feeding and discharging plate heat exchanger and a first discharging temperature sensor, and the discharging control unit comprises a discharging valve and a return valve. The prepared xylose liquid exchanges heat with the hemicellulose liquid in the feeding and discharging plate heat exchanger, so that the temperature of the xylose liquid is reduced, and the temperature of the hemicellulose liquid is increased.According to the utility model, feeding and discharging heat exchange is carried out simultaneously, the energy consumption can be greatly reduced, continuous feeding and discharging are realized, theproduction efficiency is improved, and the worker operation is simplified.
