    介绍  Introduction

    扩散机型号250被设计为一个通用气溶胶烘干机。烘干机的一个进水陷阱在去除粗水滴。 The Diffusion Dryer Model 250 is designed as a general-purpose aerosol dryer. A water trap at the inlet of the dryer removes coarse water droplets. 气雾剂,然后通过一个可移动的磁带含有硅凝胶。 The aerosol is then passed through a removable cartridge containing the silica gel. 墨盒是由两个同心圆筒,一个内细丝网屏幕和一个外网的屏幕。 The cartridge is formed by two concentric cylinders, an inner fine wire mesh screen and an outer wire mesh screen.
     
     由于气溶胶墨盒穿过的内管,水蒸汽扩散通过筛网进入硅胶。 As the aerosol goes through the inner cylinder of the cartridge, the water vapor diffuses into the silica gel through the mesh screen. 硅胶是一个不规则的珠子无定形二氧化硅,这是很难综合或制作的不规则的形式硬颗粒。 Silica gel is an amorphous form of silicon dioxide, which is synthetically produced in the form of hard irregular granules or hard irregular beads. 阿联锁微腔多孔结构提供了一个非常高的表面积(每克800平方米)。 A micro porous structure of interlocking cavities gives a very high surface area (800 square meters per gram). 正是这种结构使得高容量的硅胶干燥剂。 It is this structure that makes silica gel a high capacity desiccant. 坚持以水分子凝胶表面,因为它表现出了周围的空气低蒸气压比。 Water molecules adhere to the gels surface because it exhibits a lower vapor pressure than the surrounding air. 当压力达到平衡,不再发生吸附。 When pressure equilibrium is reached, no more adsorption occurs. 硅凝胶的美丽,是其内部的物理吸附的水蒸汽进入毛孔。没有化学反应,没有按产品或副作用。即便饱和水蒸汽,硅胶仍具有形状外观干燥的产品,其不变。 The beauty of silica gel is the physical adsorption of water vapor into its internal pores. There is no chemical reaction, no by products or side effects. Even when saturated with water vapor, silica gel still has the appearance of a dry product, its shape unchanged. 硅胶是一种很容易再生的烤箱在250 ° F的3个小时。 The silica gel is easily regenerated in an oven at 250°F for three hours.
     
    粒子损失最小化,因为气溶胶粒子不来接触到硅凝胶。 Particle loss is minimized because the aerosol particles do not come into contact with the silica gel.
