一、工作原理及應用范圍介紹 Introduction of Working Principle and Scope of Application
脈沖氣流干燥又稱為瞬間干燥，它是利用高速熱空氣氣流帶動物料作瞬間加速運動后又瞬間降速運動，形成脈沖式運動。其目的是強化傳熱傳質，從而達到高效、快速、瞬間脫除水分之目的。對于熱敏性或低熔點物料不會造成過熱或分解，是一種連續、高效、快速的固體流態化瞬間脫除水分的干燥方式，適用于粒徑范圍在5μm~5mm之間的粉粒狀物料表面水的快速干燥。且所干燥的物料，不會產生變質現象。適用于制藥、化工、食品、建材、塑料等行業的粉狀、顆粒狀物料的干燥脫水。如：
l 醫藥食品：、苯茶吡唑酮、茶粕、草酸催化劑、沉淀炭粉、對乙酰氮基苯磺酰氨、、哆耳瑪托、、焦硅酸鈉、糠氯酸咖啡渣四環素、玉米蛋白。
l 化工行業：ABC中間體、ABS樹脂、ASC、白炭黑、促進劑mdm、觸媒、對苯二酸、二乙苯銨、、活性碳、氟硅酸鈉、氟石礦、硅膠粉末、合成樹脂、磷酸鈣、聚丙烯樹脂、三氧化鐵、碳酸鈣、氧化鐵、石膏緩凝劑、木粉、木屑、米糠。
Pulse pneumatic drying is also called instant drying, which forms pulse-type movement by using high-speed hot air flow to drive the material to make instant deceleration movement after instant acceleration movement. Its purpose is to intensify the heat and mass transfer so as to achieve efficient, fast and instant dehydration. It may not cause overheat or decomposition to the materials with heat sensitivity or low melting point. It is a continuous, efficient and fast drying method of fluidizing instant dehydration for solids and applicable to fast removing surface water from 5μm~5mm powdery and granular materials. This method may not deteriorate the materials dried and is applicable to drying and dehydrating powdery and granular materials in such industries as pharmaceuticals, chemical engineering, food, building materials and plastics, as follows:
l Pharmaceuticals and food: methaqualone, benzene tea pyrazolone, tea seed cake, Oxalic acid catalyst, precipitated carbon powder, p- acetnitrilobenzene sulfonyl ammonia, p-aminosalicylic acid, Duoermatuo, aureomycin, coke sodium silicate, chaff chlorate coffee grounds tetracycline and corn protein.
l Chemical engineering industry: ABC intermediate, ABS resin, ASC, white carbon black, accelerant mdm, contact agent, terephthalic acid, diethylaniline, titanium dioxide, active carbon, sodium fluosilicate, fluorspar, silica gel powder, synthetic resin, calcium phosphate, polypropylene, ferric oxide, calcium carbonate, iron oxide, calcium sulphate retarder, wood powder, sawdust and rice bran.
二、特點Characteristics
1. 顆粒在氣流中高速度分散呈懸浮狀態，氣固兩項間傳熱傳質的有效性增大。同時由于采用脈沖管道，使得氣固兩項間的相對速度相差比較大，體積傳熱系數也較高，整體熱效率在流化干燥機中是較高的。
2. 脈沖氣流干燥設備結構簡單、緊湊、體積小，整套機組造價相對較低。
3. 干燥時間極短(只有0.5—2秒)，適用于熱敏性物料。
4. 氣流干燥物料全過程都在管道中完成，產品不與外界接觸，污染小、質量好，操作方便自動化程度高、產品品相好。
1.Particles disperse at high speed in the air flow and is in the suspending state, with the efficiency of heat and mass transfer between gas and solid phases increasing. At the same time, the pulse tube adopted increases the difference between the relative velocities of gas and solid phases and increases the volumetric heat transfer coefficient. So the overall heat efficiency is the highest among the fluidized driers.
2.The pulse pneumatic drier is a simple and compact structure with small volume. The whole set of unit costs little relatively.
3.The drying time is very short (only 0.5-2 seconds). So the equipment is applicable to heat sensitive materials.
4.Pneumatic drying of materials is fully completed in the tube. The products don’t contact with the outside, so there is little pollution and the products are of good quality and good appearance. The equipment is convenient to operate and has high degree of automation.
