Abstract

See full text

Related to is a system for preparing xylose liquid by continuously hydrolyzing hemicellulose, including a neutralizing unit, an acid-adjusting unit, a feeding unit, a liquefaction ejecting unit, a feed and discharge heat-exchanging unit and a discharge controlling unit. The neutralizing unit includes a raw material tank, a neutralizing concentrated sulfuric acid pump and a neutralizing pipeline mixer, the acid-adjusting unit includes an acid-adjusting concentrated sulfuric acid pump, an acid-adjusting pipeline mixer and an acid-adjusting tank, the feeding unit includes a feed tank, the liquefaction ejecting unit includes a liquefaction ejector and a liquefaction maintainer, the feed and discharge heat-exchanging unit includes a plate-type teed and discharge heat exchanger and a first discharge temperature sensor, and the discharge controlling unit includes a discharge valve and a reflux valve. The obtained xylose liquid exchanges heat with the hemicellulose liquid in the plate-type feed and discharge heat exchanger to decrease a temperature of the xylose liquid, whereas a temperature of the hemicellulose liquid is increased. Further disclosed is a method using the system. The simultaneous feed and discharge heat exchanges greatly reduce energy consumption, and feed and exchange are continuously run, thereby improving the production efficiency and simplifying manual operations.
