正压稀相气力输送系统简介
正压稀相气力输送系统主要是以罗茨风机产生的气流作为载体将颗粒、粉状、小块状物料输送至指定卸料点的气力输送系统，输送管道布置灵活、密闭性好、粉尘飞扬溢出少、节能环保效率高、操作简单易维护、可实现散装物料输送、自动化程度高、有效降低人员输送费用、包装和装卸费用，此外，正压气力输送系统输送过程中，还可同时对物料进行多种物料或化学工艺处理，如物料的混合、粉碎、分级、干燥、冷却等工艺处理。
系统参数:本系统主要以罗茨鼓风机为动力源，空气速度:15m/s-30m/s，物料速度:8m/s-15m/s,输送能力:1-100t/h，输送距离150米内(采用多级动力源距离可达1000m)。
系统构成
正压稀相气力输送系统的配置一般使用罗茨鼓风机作为气源,罗茨鼓风机在系统的*前端，靠风机的出口风力将物料吹送至远处的受料仓中。
正压稀相气力输送系统主要由罗茨风机、输送系统(旋转供料器、连续式输送泵、管道、切换阀门、阀门仪表等)、储灰系统(灰库、库顶除尘器、干灰散装机、加湿搅拌机、阀门仪表等)等设备构成，主要以罗茨风机为动力，将灰斗储灰用管道送入灰库储存，然后经罐车或汽车外运，因其气源压力较低，管道内灰尘浓度较低，具有输送量大，能耗低，设备磨损硝，维护费用低的优势。
正压稀相气力输送系统特点
①正压稀相气力输送系统设备自动化程度高，出气投资少，操作简单易维护，节能环保效率高;
②利用气体动压，物料以较高速度在管道中前进(8m/s-25m/s)，输送压力沿输送管道逐渐降低;
③连续输送，输送流态、输送速度与输送压力、料气比基本保持稳定，运行可靠性高，容易维护;
④应用于闭环系统时，不必增加气力缓冲设备，容易控制;⑤输送距离短，尤其适合于短距离或中等距离的气力输送;
⑥系统输送为连续式输送，亦可间断，管道内无物料积存，输送对环境污染小。
局限性和不足
1.与一些机械输送形式相比，气力输送系统能耗高，例如要求远距离的大容量输送时。
⒉.输送距离有限。可以长距离超过1000米，但实际输送距离一般为5-500米。
3.输送量有限。虽然气力输送的*大量可达400吨/小时,但大多数系统输送量为1-60吨/小时。4.研磨类产品会让管道和设备受到磨损。
5.高速输送时会使易碎产品破损。
负压稀相气力输送系统工作原理和系统优势
负压气力输送系统主要由:气力输送风机(罗茨泵、罗茨真空泵、负压罗茨风机)、取料装置、管道、缓冲仓、除尘器、卸料装置、等构成。
负压稀相气力输送系统主要采用负压罗茨真空泵作为动力源,管道输送压力为低真空状态，管道风速约10-35米/秒,物料在管道内呈雾状。负压输送起点压力等于或接近大气压，终点压力在-10到-50Kpa之间，管道真空度沿气力输送管道逐渐增高。
负压稀相气力输送系统工作原理
1、系统主要采用罗茨风机或真空泵作为气源设备，气源设备在系统的末端;2、气力输送系统取料装置部件通常采用特殊结构的吸嘴;
3、风机运转后，抽风整个系统形成负压，由管道内外存在的压力差将物料吸入输料管，物料和一部分空气同时被吸嘴吸入，并被送到缓冲仓内;
4、在缓冲仓内，物料和空气分离，被分离出的物料从缓冲仓的底部通过锁气阀卸出;5、未被分离出来的微细粉粒输送气流进入除尘器中净化，净化后的空气净除尘器，风机排入大气中。
负压稀相气力输送系统的系统优势
1、本负压系统具有气力输送量大、输送距离长、输送速度快等特点;
2、系统易于取料，适用于从低压、深处、较为狭窄的取料点取料，可用于要求取料不发尘的场合，可实现多处上料向一处集中供料。负压稀相气力输送系统适用性广，用于广泛，粉体、颗粒物均可顺利输送;
3、系统气源位于末端，润滑油或水分等不会混入输送的物料中，输送物料更清洁;
4、系统由于输料管道内为负压，因此系统管道产生磨损或存在间隙时，被输送物料也不会发生泄漏，此外，由于负压稀相气力输送系统内压力低于大气压，水分更易蒸发，所以对水分多的物料较其他方法更容易输送;
5、系统输送气体一般直接取自大气，气体的温度即为环境温度，因此负压气力输送系统适用于对温度敏感的热敏性物料
负压稀相气力输送系统散料输送效率高，由于物料在完全密闭的管道内输送，可避免输送物料受潮、污损和混入其他杂物等现象，物料输送质量高，可由多点的物料送往一处或由一处送往多处,并实现较远距离输送,此外,系统在物料输送过程中还可同时实现物料混合、粉碎、分级、干燥、冷却、除尘等多种工艺操作。
