            高密度氣力輸送系統十大特點 

                一、系統配置簡潔   

                系統內轉動部件少,其中進料閥、出料閥為轉動部件,無其他輔助設備;儀用氣源和輸送氣源公用;灰斗不需設設置氣化裝置,氣化風機和空氣加熱器;運行方式靈活多變,可連續運行,也可定期運行。

                二、系統輸送灰氣比高

                系統采用高密度的低壓栓流式輸送,消耗較少的壓縮空氣可以輸送較多的物料,輸送灰比最高可達80-100。以100m趴離的粉煤從輸送為例,輸送灰氣比可達80kg/kg。

                三、輸送能耗低

                由于輸送等量物料需要的壓縮空氣量較小,且輸送壓力較低,因此輸送能耗遠低于其他形式的氣力輸送系統。

                四、系統輸送流速低

                系統輸送速度低,以L型泵為例,出口初速度為3m/s,未速度為7m/s。

                五、管道磨損小

                由于采用較低的輸送速度,而氣力輸送的管道磨損與輸送流速成立方比例,管道流速低必然大大降低管道磨損。

                六、系統投資少,年運行維護費用低

               由于系統配置簡潔,設備少,要求的電除塵器安裝高度比較低,因此只需要較小的投資。 而由于設備可靠,檢修維護量少,系統能耗低,所以只需較低的費用就可保證系統安全可靠的運行。

                七、進料閥采用國際先進的氣動圓頂閥

                閥門結構可靠,壽命長,檢修維護簡便,采用國際最先進的氣封式結構,閥門啟閉時閥芯可以充氣密封圈之間無接觸,密封圈采用特殊配方橡膠制成,保證使用壽命可達100萬次。

                八、出料閥采用獨特的氣動圓柱旋轉閥

                閥門結構可靠,加工精度高,專為栓流式氣`力輸送系統研制。閥芯與管道平滑過渡,無曲率變化,適介于濃相栓流式輸送,采用耐磨閥芯,保證使用壽命為50萬次。(公司專用技術)

                九、閥門氣動執行器性能可靠,壽命長,推力大

                氣動執行器采用全封閉回轉推桿式直缸驅動,封閉腔內軌跡轉換,回轉輸出,即使在惡劣工況下,也不會由于執行器密封件的磨損而導致內泄漏。(公司專用技術)

                十、系統控制水平高

            系統控制采用先進的可編程控制器(PIC),有自動控制、遠方操作和就地手動控制三種控制方式,正常情況下采用自動控制方式?刂葡到y可實現運行數據和故障信號的采集自動化,對運行數據自動分析和故障判斷,并對系統中的故障實現分類報警。  

            Pneuplan Dense Phase Pneumatic Conveying
            System Ten CharacteristicS


            1. Simple System Configuration

            The moving parts of system are mininmized,only the Dome valve and In-line valve are moving parts.No other auxiliary equipment is required such as the fluidizing equipment of hoppers.The system has the flexibilty of running modes such as a continuous running mode or a periodic running mode according to the requirements.

             2. high ash/air ratio

            The system conveys the ash in a mode of "Plug" with low compressed air consumption to transfer much more material.The ash/air ratio can reach 80—100 max.taking the 100—meter distance of conveyance for example,the ash/air ratio is up t0 80kg/kg.

             3.Low energy consumption

            The energy consumption is far lower than any other conveying system since it needs a little compressed air and pressure.

             4.Low transfer velocity

            The system has a low conveying velocity normally 3m/s at the beginning and 7m/s at the end for L type conreyor

             5.Lowwear of pipeline

            The low ash conVeying speed keeps the pipe wear to the minimum for the reason that the wear of pipe is in cubic proporton to conveying speed.

             6.Low initial and maintenance cost

            The initial and maintenance cost of Pneuplan conveying system is saved due to the simple system  cofiguration,less equipment required and the low erection height requirement of ESP The system ensure its normal operation in a state of reliable and robust construction with little maintenance and low energy consumption.

             7.Advanced Pneuplan Done Valve

            with its advanced and reliable air—sealed structure,long service life and convenient maintenance,the dome valve guarantees the operation cycles up to 1 million as the inflatable Pressure tight seal never contacts with the dome when opening or closing.

             8. Unique Pneuplan In-line Valve

            With the reliable structure and high Precision of machining,the in-1ine valve is developed specially for “plug” conveying system.The service life can reach 500 thousand operation cycles.

             9.Reliable,long life and powerful pneumatic actuator

            The actuator is easy to install almost everywhere thanks to its clever structure.It can be rotated at 90-degree intervals and the valve can be connected to either end of the shaft.If necessary,the valve can be manually secured at the free end of the shaft by using a key.The position of the actuator is clearly indicated by a direction arrow marked on the actuator.Even in abnormal condition,no leakage will occur if the seal is worn.

             10.High control level

            The system is automahcally controlled by PLC with which you can undertake three control modes in-cluding auto mode,manual mode and remote control mode.In normal condition the auto made is used.The system can realize the automatic collection of running data and failure signal.It also can automahcally analyze the data and estimate the fault.The alarm of malfunction can be achieved and classified.

             

            氣力輸送系統的典型結構與原理
            Typical Structure and operation principles

               氣力輸送系統的發送器以栓塞方式輸送物料,  灰斗和發送器不需額外的流化,系統的典型結構如圖所示。系統運行一般由五個階段組成。

              階段一:可靠的、高強度的圓頂閥關閉發送器進料口

              階段二:輸送空氣導入發送器,進行濃相栓塞輸送

              階段三:輸送空氣推動灰栓沿養輸送管移動

              階段四:施加的空氣壓力一直保持到灰栓進入灰庫

              階段五:進入灰庫的空氣經布袋除塵器排出灰庫

              整個運行過程采用全自動PLC控制,也可進行就地手動控制。

            The conveying system is based on conveyors which send the ash in a non contimuous mode as “plug” without additional energy-intensive fluidizing. The typical Pneuplan pneumatic conveying system is a five-Phase process as described in the adjacent diagram

            In Phase1  an extremely reliable and robust dome valve closes the conveyor's entrance opening.

            In Phase2  conveyance air is led to the conveyor and starts the dense phase conveyance.

            In Phase3  conveying air forces the ash Plug to move along the conveying pipeline.

            In Phase4  air pressure is applied until the ash plug reaches the silo.

            In Phase5  access air is exhausted from the silo through a dust filter.

            The whole process including silo function is fully automated by PLC.Local manual control is always possible as well.
