稀相气力输送系统有三种类型，分别是正压稀相气力输送系统、负压稀相气力输送系统和正压-负压组合稀相气力输送系统。它们分别有什么特点呢？让我们一起来了解：

There are three types of dilute phase pneumatic conveying systems, namely positive pressure dilute phase pneumatic conveying system, negative pressure dilute phase pneumatic conveying system, and positive pressure negative pressure combination dilute phase pneumatic conveying system. What are their respective characteristics? Let's learn about:

正压稀相气力输送系统用于将散装材料从一个或多个来源输送到一个或多个目的地。在中长距离和更大的容量比使用的较多。简易的正压稀相气力输送系统包括：旋转阀、管道系统、增强弯管、过滤器接收器和正排量(罗茨型)鼓风机。

A positive pressure dilute phase pneumatic conveying system is used to transport bulk materials from one or more sources to one or more destinations. More used in medium to long distances and larger capacities. A simple positive pressure dilute phase pneumatic conveying system includes: rotary valve, pipeline system, reinforced elbow, filter receiver, and positive displacement (Roots type) blower.

物料通过一种特殊的加料装置(通常是旋转阀气闸或文丘里管)进入压力较高的输送线。物料经常悬浮在气流中，根据颗粒的大小和密度以相对较高的速度移动。悬浮物料-空气流在终点站通过过滤器接收器/旋风分离器分离，或直接进入工艺容器，然后排放到下游的粉尘收集设备。在这种类型的系统中，材料不通过风机/鼓风机。这样做有两个好处。，叶轮不损坏材料。第二，风机不会受到任何材料的磨损。稀相气力输送系统通常在连续的基础上运行-物料在起点不断供应，并到达目的地不中断。这使得稀相气力输送系统适合供料和连续称重的应用。

The material enters the high-pressure conveyor line through a special feeding device (usually a rotary valve air lock or Venturi tube). Materials are often suspended in the airflow and move at relatively high speeds based on the size and density of the particles. The suspended material air flow is separated at the terminal station through a filter receiver/cyclone separator, or directly enters the process container and is then discharged to the downstream dust collection equipment. In this type of system, the material does not pass through the fan/blower. This has two benefits. Firstly, the impeller does not damage the material. Secondly, the fan will not be subjected to any material wear and tear. The dilute phase pneumatic conveying system usually operates on a continuous basis - the material is continuously supplied at the starting point and reaches the destination without interruption. This makes the dilute phase pneumatic conveying system suitable for feeding and continuous weighing applications.

正压稀相气力输送系统特别适用于从单一或多个来源到单一或多个目的地输送低的物料的物料输送。这些系统是通用的，适用于不同的材料和压力，管道、配件等成本较低。

The positive pressure dilute phase pneumatic conveying system is particularly suitable for conveying low materials from a single or multiple source to a single or multiple destination. These systems are universal and suitable for different materials and pressures, with lower costs for pipes, fittings, etc.

负压稀相气力输送系统是指在大气压以下的空气压力下工作的系统。定量压力(真空)通常用于输送来自多种来源的物料，如存储容器、工艺设备、卡车和轨道车辆。到个人或多个目的地。通过使用简单的分流阀，负压稀相气力输送系统对于多种物料输送是很好的选择。但是，如果有多个输送目的地，成本也会高，因为每个目的地都必须有相应的卸料设备。

Negative pressure dilute phase pneumatic conveying system refers to a system that operates under air pressure below atmospheric pressure. Quantitative pressure (vacuum) is typically used to transport materials from multiple sources, such as storage containers, process equipment, trucks, and rail vehicles. To individual or multiple destinations. By using a simple diverter valve, the negative pressure dilute phase pneumatic conveying system is a good choice for conveying various materials. However, if there are multiple transportation destinations, the cost will also be high, as each destination must have corresponding unloading equipment.

负压稀相气力输送系统通常使用抽风机提供气流动力，通过管道将物料输送到目的地。空气和物料在旋风分离器的接收容器中被分离。物料直接进入输送线，如果需要计量，需要连接计量装置。在负压稀相气力输送中，物料不会受到污染，也没有粉尘排放到大气中。防泄漏性能，通常是基于清洁的角度来设定的，特别是在处理有危害的物料料时。这种系统的缺点是，如果负载高或输送距离长，必须要进行高真空设计。

Negative pressure dilute phase pneumatic conveying systems typically use suction fans to provide airflow power and transport materials to the destination through pipelines. Air and materials are separated in the receiving container of the cyclone separator. The material directly enters the conveyor line, and if measurement is required, a measuring device needs to be connected. In negative pressure dilute phase pneumatic conveying, materials are not contaminated and no dust is emitted into the atmosphere. Leakage prevention performance is usually set from a cleaning perspective, especially when dealing with hazardous materials. The disadvantage of this system is that if the load is high or the conveying distance is long, a high vacuum design must be carried out.
