在管道中，利用一定速度氣流的速度能或壓力能按指定的路線來輸送物料的裝置稱為氣力輸送系統，按物料在管道中的流動特征分為負壓、正壓及正負壓混合式三大類型，具有全程密閉化、自動化、管線任意布置、占地少、設備結構簡單、輸送效率高、多點供料或卸料等優點，是散裝粉粒物料現代化輸送方式之一，氣力輸送廣泛應用于化工、冶金、建材、鑄造、電廠、制藥、食品、糧油等行業。

　　The device that uses the velocity or pressure energy of a certain velocity airflow to transport materials along a specified route in a pipeline is called a pneumatic conveying system. It is divided into three types based on the flow characteristics of materials in the pipeline: negative pressure, positive pressure, and positive negative pressure mixed type. It has the advantages of full process sealing, automation, arbitrary pipeline layout, small land occupation, simple equipment structure, high conveying efficiency, multi-point feeding or unloading, and is one of the modern conveying methods for bulk powder materials. Pneumatic conveying is widely used in industries such as chemical, metallurgical, building materials, casting, power plants, pharmaceuticals, food, and grain oil.

　　正壓氣力輸送系統有哪些設備？其主要由氣源設備、供料設備、輸送管道、分離設備、控制柜等五大部分組成，除此外有時還需用到輔助設備如氣動插板閥、檢修閥、料位計等等；正壓氣力輸送系統工作原理：制造壓縮空氣的設備安裝在系統前端，其產生的壓縮空氣與供料器的物料混合后，沿輸送管道輸送到分離設備，物料與空氣分離，分離后的氣流經布袋除塵器凈化后排入大氣。恒通粉體梳理了各設備的用途，詳見以下內容。

　　What are the devices in a positive pressure pneumatic conveying system? It mainly consists of five parts: gas source equipment, feeding equipment, conveying pipelines, separation equipment, control cabinets, etc. In addition, auxiliary equipment such as pneumatic plug valves, maintenance valves, level gauges, etc. are sometimes required; Working principle of positive pressure pneumatic conveying system: The equipment for manufacturing compressed air is installed at the front end of the system. The compressed air generated is mixed with the material of the feeder and transported along the conveying pipeline to the separation equipment. The material is separated from the air, and the separated airflow is purified by a bag filter and discharged into the atmosphere. Hengtong Powder has sorted out the purposes of each equipment, as detailed below.

　　正壓氣力輸送氣源設備：是氣流增壓輸送設備的總稱，其作用是提供具有一定速度和壓力的空氣流來完成物料的輸送，即氣力輸送系統的動力源，常用的設備有羅茨鼓風機、空壓機等。

　　Positive pressure pneumatic conveying air source equipment: It is a general term for airflow boosting conveying equipment. Its function is to provide an air flow with a certain speed and pressure to complete the conveying of materials, that is, the power source of the pneumatic conveying system. Commonly used equipment includes Roots blowers, air compressors, etc.

　　正壓氣力輸送供料器設備：是用來將散粒物料供入輸料器且與氣流形成一定混合比的裝置。其結構及工作原理取決于被輸送物料的物理特性和氣力輸送系統類型，如旋轉供料器、倉泵、AV泵、螺旋輸送機等。

　　Positive pressure pneumatic conveying feeder equipment: It is a device used to feed granular materials into the feeder and form a certain mixing ratio with the airflow. Its structure and working principle depend on the physical characteristics of the conveyed material and the type of pneumatic conveying system, such as rotary feeders, bin pumps, AV pumps, screw conveyors, etc.

　　輸料管道：含輸送氣體及其與物料混合物的管道和附屬管件、是物料輸送的通道；如水平管、彎頭、分路閥等等。

　　Material conveying pipeline: a pipeline and accessory fittings that transport gases and their mixtures with materials, and is a channel for material conveying; Such as horizontal pipes, elbows, branch valves, etc.

　　正壓氣力輸送分離設備：氣力輸送系統輸送的是物料與空氣的混合物、分離設備就是在物料被輸送到終點時，把物料從氣、固雙相流中分離出來的裝置。常采用脈沖布袋除塵器：物料因自身重力大部分物料被分離出來落入目的地設備，但一些細小的顆粒或粉末則難以分離出來，排出的氣流中會含有一些微細的物料和大量的灰塵，通過布袋除塵器凈化后排入大氣中。

　　Positive pressure pneumatic conveying separation equipment: The pneumatic conveying system transports a mixture of material and air, and the separation equipment is a device that separates the material from the gas-solid two-phase flow when it is conveyed to the endpoint. Pulse bag filter is commonly used: most of the materials are separated and fall into the destination equipment due to their own gravity, but some small particles or powders are difficult to separate. The discharged airflow will contain some fine materials and a large amount of dust, which are purified by the bag filter and discharged into the atmosphere.

　　氣力輸送控制設備：PLC控制整個氣力輸送各設備的開關及工作流程，并向上位機傳送各閥門進行開關控制，通常在控制上位機LCD顯示屏幕上，顯示整套氣力輸送系統的運行狀態、使操作人員清楚現場設備的狀態。

　　Pneumatic conveying control equipment: PLC controls the switch and workflow of the entire pneumatic conveying equipment, and transmits various valves to the upper computer for switch control. Usually, the operation status of the entire pneumatic conveying system is displayed on the LCD display screen of the control upper computer, making the operator aware of the status of the on-site equipment.
