在現(xiàn)代工業(yè)生產(chǎn)中，高效、穩(wěn)定的物料輸送至關(guān)重要。氣力輸送系統(tǒng)作為一種先進(jìn)的物料輸送方式，正廣泛應(yīng)用于各個(gè)行業(yè)，為工業(yè)生產(chǎn)的順暢運(yùn)行提供了有力支持。?

Efficient and stable material transportation is crucial in modern industrial production. As an advanced material conveying method, pneumatic conveying system is widely used in various industries, providing strong support for the smooth operation of industrial production. ?

工作原理探秘?

Exploring the working principle

氣力輸送系統(tǒng)主要依靠氣體的流動(dòng)來(lái)推動(dòng)物料在管道中移動(dòng)。其基本原理是利用風(fēng)機(jī)或壓縮機(jī)產(chǎn)生具有一定壓力和流速的氣流，將物料混入其中，在氣流的攜帶下，物料通過(guò)管道被輸送到指定地點(diǎn)。根據(jù)物料特性和輸送要求的不同，氣力輸送可分為稀相輸送和密相輸送。?

The pneumatic conveying system mainly relies on the flow of gas to move materials in the pipeline. The basic principle is to use a fan or compressor to generate an airflow with a certain pressure and flow rate, mix the material into it, and transport it to a designated location through pipelines under the carrying of the airflow. According to different material characteristics and conveying requirements, pneumatic conveying can be divided into dilute phase conveying and dense phase conveying. ?

稀相輸送時(shí)，物料在氣流中呈懸浮狀態(tài)，氣固混合比相對(duì)較低，一般在 10 以下。這種輸送方式適用于顆粒較小、流動(dòng)性較好的物料，輸送速度較高，通常在 15 - 30m/s。由于物料在管道內(nèi)處于懸浮狀態(tài)，與管道壁的摩擦相對(duì)較小，能夠?qū)崿F(xiàn)長(zhǎng)距離輸送。?

During dilute phase transportation, the material is suspended in the airflow, and the gas-solid mixing ratio is relatively low, generally below 10. This conveying method is suitable for materials with small particles and good flowability, with a high conveying speed, usually between 15-30m/s. Due to the suspended state of the material inside the pipeline, the friction with the pipeline wall is relatively small, enabling long-distance transportation. ?

密相輸送則適用于一些對(duì)輸送過(guò)程要求較高、易破碎或磨蝕性較強(qiáng)的物料。在密相輸送中，物料以較低的速度、較高的濃度在管道中流動(dòng)，氣固混合比可高達(dá) 50 以上。密相輸送又可細(xì)分為栓流密相輸送和流化密相輸送。栓流密相輸送通過(guò)將物料分割成一段段料栓，利用氣體壓力推動(dòng)料栓前進(jìn)；流化密相輸送則是通過(guò)特殊的供氣裝置使物料在管道內(nèi)呈流化狀態(tài)，在氣流作用下平穩(wěn)輸送。?

Dense phase conveying is suitable for materials that have high requirements for the conveying process, are prone to breakage or have strong abrasion. In dense phase transportation, materials flow in pipelines at lower speeds and higher concentrations, and the gas-solid mixture ratio can reach over 50. Dense phase transportation can be further divided into plug flow dense phase transportation and fluidized dense phase transportation. Plug flow dense phase transportation divides materials into sections of plugs and uses gas pressure to push the plugs forward; Fluidized dense phase transportation is achieved by using a special gas supply device to make the material in a fluidized state inside the pipeline, and smoothly transported under the action of airflow. ?

多樣的系統(tǒng)類(lèi)型?

Diverse system types

根據(jù)氣源的不同，氣力輸送系統(tǒng)可分為吸送式和壓送式。吸送式氣力輸送系統(tǒng)利用真空泵在管道內(nèi)形成負(fù)壓，使物料隨外界空氣一起被吸入管道，再輸送至卸料點(diǎn)。這種方式適用于從多個(gè)供料點(diǎn)向一個(gè)卸料點(diǎn)輸送物料的情況，如在糧食加工行業(yè)中，可從不同的糧倉(cāng)向加工車(chē)間輸送谷物。其優(yōu)點(diǎn)是能在輸送過(guò)程中對(duì)物料進(jìn)行初步的篩分和除塵，且供料裝置相對(duì)簡(jiǎn)單。?

According to the different gas sources, pneumatic conveying systems can be divided into suction type and pressure type. The suction pneumatic conveying system uses a vacuum pump to create negative pressure inside the pipeline, causing the material to be sucked into the pipeline along with the outside air and then transported to the discharge point. This method is suitable for conveying materials from multiple feeding points to one unloading point, such as in the grain processing industry, where grains can be transported from different silos to the processing workshop. Its advantage is that it can perform preliminary screening and dust removal on materials during the conveying process, and the feeding device is relatively simple. ?

壓送式氣力輸送系統(tǒng)則依靠空壓機(jī)等設(shè)備向管道內(nèi)輸入高壓氣體，將物料從供料點(diǎn)壓送至卸料點(diǎn)。它適用于從一個(gè)供料點(diǎn)向多個(gè)卸料點(diǎn)輸送物料的場(chǎng)合，在化工生產(chǎn)中，常用來(lái)將原料輸送到不同的反應(yīng)裝置。壓送式氣力輸送系統(tǒng)輸送能力較大，輸送距離更遠(yuǎn)，且可在正壓環(huán)境下進(jìn)行輸送，避免了外界雜質(zhì)的混入。

The pressure feeding pneumatic conveying system relies on equipment such as air compressors to input high-pressure gas into the pipeline, and pressurizes the material from the feeding point to the unloading point. It is suitable for conveying materials from one feeding point to multiple unloading points. In chemical production, it is commonly used to transport raw materials to different reaction devices. The pressure pneumatic conveying system has a large conveying capacity, longer conveying distance, and can be conveyed in a positive pressure environment, avoiding the mixing of external impurities.
