Preparation method and device for industrial mass production of porous graphene powder

The invention discloses a preparation method for industrial mass production of porous graphene powder. The preparation method comprises the following steps: (1) carrying out ultrasonic oscillation on liquid polyimide in an ultrasonic sprayer so as to atomize the liquid polyimide into vaporific particles; (2) enabling the mist particles of the polyimide to enter a preparation cylinder, and performing carbon dioxide laser irradiation in the preparation cylinder; and (3) irradiating the vaporific particles of the polyimide by carbon dioxide laser to form high-purity porous graphene powder, and falling the high-purity porous graphene powder at the bottom of the preparation cylinder. The novel mass production method of the high-purity porous graphene powder can be provided, and excellent production economic benefits can be achieved. 本发明公开了一种工业化量产多孔石墨烯粉末的制备方法；其制备方法包括以下步骤：(1)取液态的聚酰亚胺于一超音波喷雾器内进行超音波振荡而使的雾化为雾状粒子；(2)使该聚酰亚胺的雾状粒子进入一制备筒，并于该制备筒内进行二氧化碳雷射照射；(3)该聚酰亚胺的雾状粒子经二氧化碳雷射照射后，形成高纯度多孔石墨烯粉末，并落于该制备筒的底部；藉此，能提供一种新的高纯度多孔石墨烯粉末量
