壓力噴霧

一、工作原理與應用范圍介紹 Introduction of Working Principle and Scope of Application

溶液或懸浮液、漿料等經過高壓泵將料液壓至2-20MPa送入霧化器將料液噴成霧狀，然后與順（逆）流的熱空氣充分進行熱交換從而達到快速干燥之目的，廣泛適用于大批量（小時產量可達幾十噸）的物料快速瞬間脫水干燥。

Solution or suspension, sizing agent, etc. are pressurized by the high pressure pump at 2-20MPa and sent into the atomizer, which spays the feed liquid into vapor. Then, the vapor will fully conduct heat exchange with the downstream (upstream) hot air, achieving the purpose of rapid drying. It is widely applied in rapid and constant dehydration and drying of large batches of materials (scores of tons in a hour).

二、特點Characteristics

1.壓力噴干出來的產品相對離心噴干出來的產品粒徑粗、產品的堆密度大。

2.小時產量大，采用多噴頭可實現小時產量十幾噸甚至幾十噸。

3.干燥速度快，料液經霧化后表面積大大增加，在熱風氣流中瞬間就可蒸發95%-98%的水份，完成干燥的時間僅需十幾秒到數十秒，特別適用于熱敏性物料的干燥。

4.所得產品為球狀顆粒，粒度均勻，流動性好，溶解性好，產品純度高，質量好。

5.使用范圍廣，根據物料的特性，可以用熱風干燥，也可以用冷風造粒，對物料的適應性強。

6.操作簡單穩定，控制方便，容易實現自動化作業。

1.    The particle size and bulk density of products spray-dried under pressure are larger than those spray-dried in a centrifugal way.

2.     The application of multiple nozzles can realize the hourly output of over ten and even scores of tons.

3.     The drying speed is fast. After atomization, the superficial area of feed liquid will be increased largely. 95%-98% of moisture can be evaporated instantly in the hot air flow. The time for completing drying takes only over ten to scores of seconds. It is particularly applicable to the drying of heat sensitive materials.

4.     The products are epigranular spherical particles with good mobility, solubleness and quality and high purity.

5.     It has a large scope of application. Depending on the characteristics of materials, it can be used for hot air drying and cold air pelleting and is strongly adaptable to materials.

6.    The operation is simple, stable and easy to control, and automated operation can be achieved easily.
