其主要结构特点是在干燥湿底部的周围装有几根热空气进口管，在每根热空气管上装有脉冲阀，它们按一定的频率和次序开启，开启时间与床层厚度和物料性能有关，当气体突然引进时，在短时间内形成一个脉冲，使粒子剧烈流化，促使物料之间进行强烈的传热与传质，当阀门关闭时，床层的流化状态逐渐消失，则物料处于静止状态，此时仍通入部分气体通过床层，以便下一个脉冲能有效地在床中传递。其优点在于：传热系数高，干燥时间短，空气耗量减少，电能耗量低。

可做为净水器的前置预处理器一般的净水器目前常用的预处理器均采用PP棉，其过滤精度号称是1-5微米之间。主要是延长后面滤芯的使用寿命，因存在更换频率过高以及滤芯不能实现反冲洗，其功能有被前置过滤器所取代的趋势（但因其成本低廉，目前仍被大量使用，PP棉存在的问题：更换周期比较短，价格透明没有任何的利润空间；杂质积累以后，不能及时排出造成二次污染，容易滋生细菌；大多数PP棉均采用透明材质，容易长青苔）。

为改进RS-232通信距离短、速率低的缺点，RS-422定义了一种平衡通信接口，将传输速率提高到1Mb/s，传输距离延长到4英尺，并允许在一条平衡总线上连接多1个接收器。RS-422是一种单机发送、多机接收的单向、平衡传输规范，被命名为TIA/EIA-422-A标准。为扩展应用范围，EIA又于1983年在RS-422基础上制定了RS-485标准，增加了发送器的驱动能力和冲突保护特性，扩展了总线共模范围，后命名为TIA/EIA-485-A标准。

为项目寻找佳和经济的解决方案，是洁净室外换气项目的基本的目标理念。如表1所示，换气次数和再循环数量变化对于确定房间的级别是十分重要的。，通过3次的换气次数能够达到M2级洁净室的要求，但也可能54次的换气次数仍不能满足要求。房间内污染物的比率和实际微粒产生情况，是影响洁净室空气换气次数的主要因素。在生产过程中，不对其他因素产生任何影响的情况下，清除微粒的速度是非常重要的。其他可能影响再循环空气数量的因素是：房间的结构、设备的位置、设备表面温度、空气对流、气流类型(单向通过敏感区或者通过全空间)、操作空间和规章、使用的材料和化学药品等。
