垂直正压关风器由正压关风器和料气混合加速器组成，关风器采用上进料垂直出料设计，物料经过加速器高效流化，输送管道不堵塞，其内部空气流的设计大大提高了输送效率和使用寿命，避免了物料对关风器内部的冲击和磨蚀，适用于物料比较重、磨蚀性较强的颗粒物料输送。

The vertical positive pressure airlock is composed of positive pressure airlock and a material-gas mixing
accelerator. The airlock adopts the design of upper feeding and vertical discharging. The material is efficiently
fluidized by the accelerator, and the conveying pipeline is not blocked. The design of the internal air flow greatly
improves the conveying efficiency and service life, and avoids the impact and abrasion of the material on the
inside of the airlock. It is suitable for conveying granular materials with heavy materials and strong abrasiveness.
