1.稀相输送

1. Dilute phase transportation

连续输送,或批次输送量较大，有两种输送模式。如果物料在管道中以悬浮态输送为稀相输送。如果材料在全部或部分管道中以低速、非悬浮态的方式进行输送，为浓相输送。几乎任何材料，无论颗粒大小，形状或密度，可以以稀相，悬浮流的形式进行输送。

There are two conveying modes for continuous conveying or batch conveying with large quantities. If the material is transported in a suspended state in the pipeline, it is referred to as dilute phase transportation. If the material is transported in a low-speed, non suspended manner in all or part of the pipeline, it is referred to as dense phase transportation. Almost any material, regardless of particle size, shape, or density, can be transported in the form of dilute phase, suspended flow.

2.密相输送

2. Dense phase transportation

密相输送有两种模式。一种是移动床流，物料在管道底部形成沙丘状移动，或作为一个脉动移动床移动。另外一种是栓柱流，物料在管道中形成充满整个管道截面的料栓与气栓相间的形态。只有在被输送物料有良好的存气性，才可以以移动床形态流动。只有在被输送物料有良好的透气性，才可以以栓柱流形态流动。

There are two modes of dense phase transportation. One type is moving bed flow, where materials form sand dune like movements at the bottom of the pipeline, or move as a pulsating moving bed. Another type is plug column flow, where the material forms a pattern of alternating material plugs and gas plugs that fill the entire cross-section of the pipeline. Only when the conveyed material has good gas storage capacity can it flow in a moving bed form. Only when the conveyed material has good breathability can it flow in the form of a plug column flow.

3.负压输送

3. Negative pressure conveying

稀相输送必须有较高的输送空气流速。输送非常细的粉末的气速为2400英尺/分（注：12米/秒）左右，细颗粒状物料为3200英尺/分钟（16米/秒），输送大颗粒和高密度的物料需要更高气速。浓相输送，气速可降至600英尺/分（3米/秒），某些情况下更低。由于细颗粒大小需提供必要的空气保留，在移动床型浓相输送中，粒子密度对小输送空气流速没有很大影响。　　1.稀相输送

Dilute phase transportation requires a high air flow rate for transportation. The gas velocity for conveying very fine powders is around 2400 feet per minute (note: 12 meters per second), for fine granular materials it is 3200 feet per minute (16 meters per second), and higher gas velocities are required for conveying large particles and high-density materials. Concentrated phase transportation, the gas velocity can be reduced to 600 feet per minute (3 meters per second), and in some cases even lower. Due to the need to provide necessary air retention for fine particle size, particle density does not have a significant impact on the flow rate of small conveying air in a moving bed type dense phase transport. 1.
