粉粒物料氣力輸送原理,就是將粉粒物料利用空氣將其混合,,形成一種特定濃度的氣固混合物,,在壓差作用下進入輸送管道,將氣固混合物沿管道向前推進直達受料倉內(nèi),,固體物料在重力下落入受料倉內(nèi),,空氣經(jīng)倉頂除塵器過濾后排入大氣,實現(xiàn)氣固分離,,達到粉粒物料遠距離輸送目的,。
The pneumatic conveying principle of powder materials is that the powder materials are mixed with air to form a specific concentration of gas-solid mixture, which enters the conveying pipeline under the action of differential pressure, and the gas-solid mixture is pushed forward along the pipeline to the receiving bin. The solid materials fall into the receiving bin under gravity, and the air is filtered by the dust collector on the top of the bin and discharged into the atmosphere to realize gas-solid separation and achieve the purpose of long-distance conveying of powder materials.
粉粒物料氣力輸送系統(tǒng),工藝要求各有不同,,是按實際工況通過量身定制而設計的智能化粉體輸送裝備,。主要分為;高正壓,、低正壓,、真空負壓。

粉粒物料輸送設計原則,根據(jù)物料特性(比如:物料堆比重,、細度,、莫氏硬度、含水率,、安息角,、溫度)等系列參數(shù),物料輸送量,、輸送距離,、氣固比、管內(nèi)流速,、管道轉向方式,、彎頭數(shù)量、輸送高度,、受料倉形式,,上下游工藝,智能化控制等相關要求而設計的,。
The design principle of powder material conveying is designed according to a series of parameters such as material characteristics (such as material pile specific gravity, fineness, Mohs hardness, moisture content, rest angle and temperature), material conveying capacity, conveying distance, gas-solid ratio, flow rate in the pipe, pipeline steering mode, number of elbows, conveying height, silo form, upstream and downstream process, intelligent control and other relevant requirements.
物料高濃度輸送,,固比高,氣比低,,耗氣量相應降低,,則空壓機能耗也相應降低,物料低濃度輸送,,固比較低,,氣比較高,耗氣量相應增加,,則空壓機能耗也相應增加,。在粉體氣力輸送系統(tǒng)設計中,,須綜合物料特性、輸送距離,、彎頭數(shù)量,、輸送高度等因數(shù),適當提高輸送濃度,,使系統(tǒng)更,。在輸送距離較遠,彎頭較多,,垂直輸送較高的工況中,,不建議將輸送濃度設計過高,容易產(chǎn)生堵管現(xiàn)象,。
When the material is transported with high concentration, the solid ratio is high, the gas ratio is low, and the gas consumption is reduced accordingly, the energy consumption of the air compressor is also reduced accordingly. When the material is transported with low concentration, the solid ratio is low, the gas ratio is high, and the gas consumption is increased accordingly, the energy consumption of the air compressor is also increased accordingly. In the design of powder pneumatic conveying system, the factors such as material characteristics, conveying distance, number of elbows and conveying height must be integrated to appropriately improve the conveying concentration and make the system more energy-saving. Under the conditions of long conveying distance, more elbows and high vertical conveying, it is not recommended to design the conveying concentration too high, which is easy to cause pipe blockage.
掌握氣力輸送系統(tǒng)核心技術也是達到物料濃相輸送的關鍵,,從目前看,有外旁路式,,內(nèi)套管式,,氣刀式等,輸送工況不同則技術方案不同,。
Mastering the core technology of pneumatic conveying system is also the key to achieve dense phase energy-saving conveying of materials. At present, there are external bypass type, internal casing type, air knife type, etc. the technical schemes are different under different conveying conditions.
