The invention discloses a method for preparing hydrogen by utilizing waste biomass, and the method comprises the following steps of: firstly, processing the waste biomass into semi-finished product fluid slurry; then, carrying out water vapor gasification treatment on the semi-finished product fluid slurry, thus obtaining crude oil; carrying out supercritical water gasification treatment on the crude oil, thus obtaining crude bio-gas; and finally, carrying out low-temperature transformation treatment on the crude bio-gas, thus obtaining transformed gas. The hydrogen is prepared by two-step gasification and low-temperature transformation, so that the biomass gasification efficiency is high, tar carbon deposit blockage can be avoided, continuous feeding is realized, and the prepared hydrogen is high in purity; furthermore, in the low-temperature transformation treatment, precious metals and rare-earth elements are added on the basis of a copper-zinc-aluminum catalyst, so that the reaction temperature is remarkably reduced, the activity and stability of the catalyst are improved, and the conversion rate of CO is high during the low-temperature transformation treatment.

The invention discloses a long-stroke high-precision piezoelectric displacement platform and a driving method thereof. The technical problems that a current piezoelectric stick-slip displacement platform is limited in stroke, unstable in motion and weak in bearing capacity are solved. The micro-displacement platform comprises a fixing base, a driving stator, a bearing sliding block, a top cover, aguide rail, a thread pair, stator mounting screws, top cover mounting screws and guide rail mounting screws. The driving stator extends slowly to drive a flexible hinge to deform through a stacked type piezoelectric ceramic, and continuous feeding of the bearing sliding block is realized by introducing sawtooth wave electric signals to the stacked type piezoelectric ceramic. The platform has thecharacteristics of being simple in structure, high in stability, large in stroke and high in load capacity, and has a good application prospect in the micro-nano driving and positioning fields such asoptical precision instruments and semiconductor processing.

The invention relates to the field of preparation of iron, silicon and aluminum powder, in particular to a continuous feeding air separation device. The continuous feeding air separation device is characterized in that an air separation wheel is additionally arranged in a ball mill, so that the air separation wheel is used to pump powder which is ground in the ball mill and meets the fineness requirement into a powder separation system at any time, and the powder which meets the requirement is effectively prevented from being ground into fine waste powder because of being in the ball mill fora long time. By the adoption of the device, the capacity and efficiency requirements of the ball mill can be effectively met, so that the aim of ensuring the maximum output of products is realized.
