氣力輸送行業(yè)的發(fā)展現(xiàn)狀

The current development status of pneumatic conveying industry

　　一、氣力輸送行業(yè)基本情況及特征

1、 Basic situation and characteristics of pneumatic conveying industry

　　氣力輸送系統(tǒng)是利用氣流的能量，在密閉管道內(nèi)沿氣流方向輸送粉粒體物料的成套裝備，是流態(tài)化技術(shù)的一種具體應(yīng)用。氣力輸送系統(tǒng)通過(guò)特定的供料裝置，將被輸送的物料定量送入管道，利用正負(fù)壓氣體（空氣、氮?dú)?、二氧化碳或氯甲烷等）將物料輸送到指定地點(diǎn)，并保證所有輸送設(shè)備和儀表通過(guò)控制系統(tǒng)實(shí)現(xiàn)自動(dòng)、有序、安全地運(yùn)行。

Pneumatic conveying system is a complete set of equipment that utilizes the energy of airflow to transport powder and particle materials along the direction of airflow in a closed pipeline. It is a specific application of fluidization technology. The pneumatic conveying system uses a specific feeding device to quantitatively feed the transported material into the pipeline, and uses positive and negative pressure gases (air, nitrogen, carbon dioxide, or chloroform, etc.) to transport the material to the designated location, ensuring that all conveying equipment and instruments operate automatically, orderly, and safely through the control system.

　　氣力輸送系統(tǒng)布置靈活、操作方便，可進(jìn)行水平、垂直或傾斜方向的輸送，在輸送過(guò)程中還可同時(shí)進(jìn)行物料的加熱、冷卻、干燥和分級(jí)等物理操作或某些化學(xué)操作。

The pneumatic conveying system is flexible in layout and easy to operate, and can transport materials in horizontal, vertical, or inclined directions. During the conveying process, it can also perform physical operations such as heating, cooling, drying, and grading of materials or certain chemical operations simultaneously.

　?。?）國(guó)際發(fā)展現(xiàn)狀

(1) International development status

　　氣力輸送技術(shù)始于十九世紀(jì)末的英國(guó)，經(jīng)過(guò)一百余年的發(fā)展及實(shí)踐，在技術(shù)及設(shè)備方面取得很大進(jìn)展。目前，在國(guó)外發(fā)達(dá)國(guó)家，氣力輸送行業(yè)已成為工業(yè)自動(dòng)化以及智能制造體系的重要組成部分。隨著全球制造業(yè)產(chǎn)業(yè)結(jié)構(gòu)的升級(jí)轉(zhuǎn)型，氣力輸送設(shè)備廣泛應(yīng)用于石化、鋼鐵、精細(xì)化工、橡膠、食品醫(yī)藥等領(lǐng)域。

Pneumatic conveying technology began in late 19th century England, and after more than a hundred years of development and practice, significant progress has been made in technology and equipment. At present, in developed countries abroad, the pneumatic conveying industry has become an important component of industrial automation and intelligent manufacturing systems. With the upgrading and transformation of the global manufacturing industry structure, pneumatic conveying equipment is widely used in fields such as petrochemicals, steel, fine chemicals, rubber, food and medicine.

(2) Domestic development status

　　氣力輸送技術(shù)在我國(guó)起步較晚，20世紀(jì)50年代末才開(kāi)始有所研究，60年代以后，倉(cāng)泵正壓氣力輸送技術(shù)開(kāi)始在國(guó)內(nèi)得到應(yīng)用，改革開(kāi)放后，石化、化工行業(yè)相繼進(jìn)口了大量聚烯烴裝置配套的氣流輸送系統(tǒng)，直到21世紀(jì)初逐漸開(kāi)始國(guó)產(chǎn)化系統(tǒng)替代進(jìn)口。

The pneumatic conveying technology started relatively late in China, and research began in the late 1950s. After the 1960s, the positive pressure pneumatic conveying technology of the warehouse pump began to be applied in China. After the reform and opening up, the petrochemical and chemical industries successively imported a large number of airflow conveying systems supporting polyolefin units. It was not until the early 21st century that domestic systems gradually began to replace imports.

　　隨著經(jīng)濟(jì)的快速發(fā)展，各行業(yè)的生產(chǎn)規(guī)模在不斷擴(kuò)大，產(chǎn)業(yè)結(jié)構(gòu)也在升級(jí)轉(zhuǎn)型，化工、水泥、制藥、火力發(fā)電、糧食加工等行業(yè)在生產(chǎn)過(guò)程中對(duì)物料的純度要求、輸送效率及環(huán)境保護(hù)等問(wèn)題更為重視，諸多行業(yè)普遍采用粉粒體輸送設(shè)備或利用相關(guān)設(shè)備改造取代人工。目前，氣力輸送系統(tǒng)在石化、化工等行業(yè)中已實(shí)現(xiàn)大規(guī)模應(yīng)用，在食品、制藥等行業(yè)得到廣泛應(yīng)用，在硅材料、新能源、新材料等國(guó)民經(jīng)濟(jì)新興行業(yè)和領(lǐng)域逐步推廣應(yīng)用。

With the rapid development of the economy, the production scale of various industries is constantly expanding, and the industrial structure is also upgrading and transforming. Industries such as chemical, cement, pharmaceutical, thermal power generation, and grain processing pay more attention to the purity requirements, conveying efficiency, and environmental protection of materials in the production process. Many industries generally adopt powder particle conveying equipment or use related equipment to transform and replace manual labor. At present, pneumatic conveying systems have been widely applied in industries such as petrochemicals and chemicals, and have been widely applied in industries such as food and pharmaceuticals. They are gradually being promoted and applied in emerging industries and fields of the national economy such as silicon materials, new energy, and new materials.

　　氣力輸送是以密封式輸送管道代替?zhèn)鹘y(tǒng)的機(jī)械輸送物料并能夠同時(shí)完成物料處理的一種工藝過(guò)程，能夠?qū)崿F(xiàn)高效、清潔生產(chǎn)。隨著制造業(yè)的智能化、自動(dòng)化技術(shù)的提升，未來(lái)氣力輸送系統(tǒng)的應(yīng)用領(lǐng)域?qū)?huì)持續(xù)擴(kuò)張。因此，氣力輸送行業(yè)整體市場(chǎng)具備較大的發(fā)展空間。

Pneumatic conveying is a process that uses sealed conveying pipelines instead of traditional mechanical conveying of materials and can simultaneously complete material processing, achieving efficient and clean production. With the improvement of intelligence and automation technology in the manufacturing industry, the application field of pneumatic conveying systems will continue to expand in the future. Therefore, the overall market of the pneumatic conveying industry has great development potential.
