The invention relates to a
straw raw material clean co-production technology and an efficient hot-pressing device. The device is mainly composed of whole-
system straw preparation
raw material equipment, compression type
raw material input equipment, a raw material cooking phase-change
hydrolysis container,
hydrolysate heat preservation, pressure maintaining, discharging and conveying equipment, ahydrolysate high-temperature high-pressure
solid-liquid separation unit,
liquid phase conveying equipment, liquid-phase
hemicellulose and base material production equipment,
solid-phase stirring and conveying equipment, a high-temperature and high-pressure
defibrator unit, defibrated material heat preservation, pressure maintaining, discharging, steam exhausting, stirring and conveying equipment,a defibrated material high-temperature and high-pressure
solid-liquid separation unit, defibration water-
liquid circulation equipment, defibration steam purification,
heat supply and heat source equipment, defibration vapour removal and
recovery equipment and the like. The device has the beneficial effects that the textbook confinement of
plant cooking,
hydrolysate spraying and normal-state solid-liquid separation is broken through, and a clean co-production technology and efficient hot-pressing equipment taking
plant cooking, defibration and heat and pressure preservation solid-liquid separation as cores are innovated, so that the last kilometer of efficient conversion between
straw solid
waste treatment and raw material utilization is broken through.
