氣力輸送行業的發展現狀

The current development status of pneumatic conveying industry

　　一、氣力輸送行業基本情況及特征

1、 Basic situation and characteristics of pneumatic conveying industry

　　氣力輸送系統是利用氣流的能量，在密閉管道內沿氣流方向輸送粉粒體物料的成套裝備，是流態化技術的一種具體應用。氣力輸送系統通過特定的供料裝置，將被輸送的物料定量送入管道，利用正負壓氣體（空氣、氮氣、二氧化碳或氯甲烷等）將物料輸送到指定地點，并保證所有輸送設備和儀表通過控制系統實現自動、有序、安全地運行。

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.

　　氣力輸送系統布置靈活、操作方便，可進行水平、垂直或傾斜方向的輸送，在輸送過程中還可同時進行物料的加熱、冷卻、干燥和分級等物理操作或某些化學操作。

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.

(1) International development status

　　氣力輸送技術始于十九世紀末的英國，經過一百余年的發展及實踐，在技術及設備方面取得很大進展。目前，在國外發達國家，氣力輸送行業已成為工業自動化以及智能制造體系的重要組成部分。隨著全球制造業產業結構的升級轉型，氣力輸送設備廣泛應用于石化、鋼鐵、精細化工、橡膠、食品醫藥等領域。

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

　　氣力輸送技術在我國起步較晚，20世紀50年代末才開始有所研究，60年代以后，倉泵正壓氣力輸送技術開始在國內得到應用，改革開放后，石化、化工行業相繼進口了大量聚烯烴裝置配套的氣流輸送系統，直到21世紀初逐漸開始國產化系統替代進口。

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.

　　隨著經濟的快速發展，各行業的生產規模在不斷擴大，產業結構也在升級轉型，化工、水泥、制藥、火力發電、糧食加工等行業在生產過程中對物料的純度要求、輸送效率及環境保護等問題更為重視，諸多行業普遍采用粉粒體輸送設備或利用相關設備改造取代人工。目前，氣力輸送系統在石化、化工等行業中已實現大規模應用，在食品、制藥等行業得到廣泛應用，在硅材料、新能源、新材料等國民經濟新興行業和領域逐步推廣應用。

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傳統的機械輸送物料并能夠同時完成物料處理的一種工藝過程，能夠實現高效、清潔生產。隨著制造業的智能化、自動化技術的提升，未來氣力輸送系統的應用領域將會持續擴張。因此，氣力輸送行業整體市場具備較大的發展空間。

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.
