气力输送行业的发展现状

The current development status of pneumatic conveying industry

　　一、气力输送行业基本情况及特征

1、 Basic situation and characteristics of pneumatic conveying industry

　　气力输送系统是利用气流的能量，在密闭管道内沿气流方向输送粉粒体物料的成套装备，是流态化技术的一种具体应用。气力输送系统通过特定的供料装置，将被输送的物料定量送入管道，利用正负压气体（空气、氮气、二氧化碳或氯甲烷等）将物料输送到指定地点，并保证所有输送设备和仪表通过控制系统实现自动、有序、地运行。

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.

　　气力输送系统布置灵活、操作方便，可进行水平、垂直或倾斜方向的输送，在输送过程中还可同时进行物料的加热、冷却、干燥和分级等物理操作或某些化学操作。

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）国际发展现状

(1) International development status

　　气力输送技术始于十九世纪末的英国，经过一百余年的发展及实践，在技术及设备方面取得很大进展。目前，在国外发达，气力输送行业已成为工业自动化以及智能制造体系的重要组成部分。随着全球制造业产业结构的升级转型，气力输送设备广泛应用于石化、钢铁、精细化工、橡胶、食品医药等领域。

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）国内发展现状

(2) Domestic development status

　　气力输送技术在我国起步较晚，20世纪50年代末才开始有所研究，60年代以后，仓泵正压气力输送技术开始在国内得到应用，改革开放后，石化、化工行业相继进口了大量聚烯烃装置配套的气流输送系统，直到21世纪初逐渐开始国产化系统替代进口。

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.

　　随着经济的快速发展，各行业的生产规模在不断扩大，产业结构也在升级转型，化工、水泥、制药、火力发电、粮食加工等行业在生产过程中对物料的纯度要求、输送效率及环境保护等问题更为重视，诸多行业普遍采用粉粒体输送设备或利用相关设备改造取代人工。目前，气力输送系统在石化、化工等行业中已实现大规模应用，在食品、制药等行业得到广泛应用，在硅材料、新能源、新材料等国民经济新兴行业和领域逐步推广应用。

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.

　　气力输送是以密封式输送管道代替传统的机械输送物料并能够同时完成物料处理的一种工艺过程，能够实现、清洁生产。随着制造业的智能化、自动化技术的提升，未来气力输送系统的应用领域将会持续扩张。因此，气力输送行业整体市场具备较大的发展空间。

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.
