氣力輸送是工程類(lèi)的施工,其中大大小小的設(shè)備有很多種,每個(gè)設(shè)備之間的互通關(guān)聯(lián)如果出現(xiàn)問(wèn)題就會(huì)造成故障,比較常見(jiàn)的就屬管道磨損了,情況嚴(yán)重的話甚會(huì)影響整個(gè)設(shè)備的運(yùn)行,所以旋轉(zhuǎn)供料器設(shè)計(jì)人員需要不斷的改進(jìn)技術(shù),提高氣力輸送系統(tǒng)的耐磨性,保證系統(tǒng)的平穩(wěn)運(yùn)行。
Pneumatic conveying is engineering construction. There are many kinds of equipment, large and small. If there is a problem in the interconnection between each equipment, it will cause failure. The more common is that the pipeline is worn. If the situation is serious, it will even affect the operation of the entire equipment. Therefore, the rotary feeder designer needs to constantly improve the technology, improve the wear resistance of the pneumatic conveying system, and ensure the smooth operation of the system.
施工經(jīng)驗(yàn)表明,耐磨供料器在氣力輸送工程中的應(yīng)用相對(duì)較好,粉體輸送的管道磨損與空氣輸送速度、所輸送貨物的磨損散裝物料的濃度、管道的直徑以及管道所用的材料有關(guān),直線和角的磨損明顯不同。對(duì)于某些輸送材料彎頭的使用壽命只有幾個(gè)小時(shí),而相同材料的直截面鋼管的使用壽命只有幾個(gè)月,這說(shuō)明旋轉(zhuǎn)供料器的使用有很大的空間,再就是從輸送設(shè)備輸送到管道的干灰的流動(dòng)性差,如干灰易吸濕,顆粒粗大,輸送設(shè)備中的干灰不能充分流化。
The construction experience shows that the wear-resistant feeder is relatively well applied in the pneumatic conveying project. The abrasion of the powder conveying pipeline is related to the air conveying speed, the abrasion of the transported goods, the concentration of bulk materials, the diameter of the pipeline and the materials used in the pipeline. The abrasion of the straight line and the angle are obviously different. For some conveying material elbows, the service life is only a few hours, while the service life of straight section steel pipes of the same material is only a few months, which shows that there is a lot of room for the use of rotary feeder, and the dry ash conveyed from the conveying equipment to the pipeline has poor fluidity, such as the dry ash is easy to absorb moisture, the particles are coarse, and the dry ash in the conveying equipment cannot be fully fluidized.
不銹鋼供料器的使用也比較廣泛,氣力輸送設(shè)備是一種密閉性的輸送設(shè)備,不受氣候條件影響,能夠解決粉塵排放的問(wèn)題,避免了粉塵的污染。另外,工作人員在使用氣力輸送設(shè)備時(shí),可以穿戴一些的防塵工具進(jìn)行自我保護(hù)。
Stainless steel feeder is also widely used. Pneumatic conveying equipment is a kind of airtight conveying equipment, which is not affected by climatic conditions, can solve the problem of dust emission and avoid dust pollution. In addition, when using pneumatic conveying equipment, workers can wear some professional dust-proof tools for self-protection.
旋轉(zhuǎn)供料器系統(tǒng)輸送的空氣質(zhì)量和體積如果不符合要求,輸送的空氣具有不穩(wěn)定的供氣量,會(huì)嚴(yán)重影響輸送風(fēng)量與輸送灰的平衡。壓縮空氣的輸送質(zhì)量不能滿足運(yùn)輸要求,如含水率過(guò)高。輸送管道的穩(wěn)定性不好,輸送材料不穩(wěn)定。隨著干灰流動(dòng)性的降低,在輸送過(guò)程中容易形成不可控的質(zhì)量流或塞流,形成不穩(wěn)定的輸送過(guò)程。
If the quality and volume of the air conveyed by the rotary feeder system do not meet the requirements, the air conveyed has an unstable air supply volume, which will seriously affect the balance between the conveyed air volume and the conveyed ash. The delivery quality of compressed air cannot meet the transportation requirements, such as high moisture content. The stability of the conveying pipeline is poor, and the conveying material is unstable. With the reduction of the fluidity of dry ash, it is easy to form uncontrollable mass flow or plug flow during the transportation process, forming an unstable transportation process.
