1.稀相輸送

1. Dilute phase transportation

連續輸送,或批次輸送量較大，有兩種輸送模式。如果物料在管道中以懸浮態(tài)輸送為稀相輸送。如果材料在全部或部分管道中以低速、非懸浮態(tài)的方式進(jìn)行輸送，為濃相輸送。幾乎任何材料，無(wú)論顆粒大小，形狀或密度，可以以稀相，懸浮流的形式進(jìn)行輸送。

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.密相輸送

2. Dense phase transportation

密相輸送有兩種模式。一種是移動(dòng)床流，物料在管道底部形成沙丘狀移動(dòng)，或作為一個(gè)脈動(dòng)移動(dòng)床移動(dòng)。另外一種是栓柱流，物料在管道中形成充滿(mǎn)整個(gè)管道截面的料栓與氣栓相間的形態(tài)。只有在被輸送物料有良好的存氣性，才可以以移動(dòng)床形態(tài)流動(dòng)。只有在被輸送物料有良好的透氣性，才可以以栓柱流形態(tài)流動(dòng)。

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.負壓輸送

3. Negative pressure conveying

稀相輸送必須有較高的輸送空氣流速。輸送非常細的粉末的氣速為2400英尺/分（注：12米/秒）左右，細顆粒狀物料為3200英尺/分鐘（16米/秒），輸送大顆粒和高密度的物料需要更高氣速。濃相輸送，氣速可降至600英尺/分（3米/秒），某些情況下更低。由于細顆粒大小需提供必要的空氣保留，在移動(dòng)床型濃相輸送中，粒子密度對小輸送空氣流速沒(méi)有很大影響?！　?.稀相輸送

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.
