氣力輸送裝置的結構簡單，操作方便，可作水平的、垂直的或傾斜方向的輸送，在輸送過程中還可同時進行物料的加熱、冷卻、干燥和氣流分級等物理操作或某些化學操作。

The structure of the pneumatic conveying device is simple and easy to operate. It can be used for horizontal, vertical, or inclined conveying. During the conveying process, it can also perform physical operations such as heating, cooling, drying, and air flow classification, as well as certain chemical operations.

為何裝備制造能成為氣力輸送設備采購商最大的市場，在2019年占比接近總市場的20%。由于實際需要不同，氣力輸送系統(tǒng)包含不同部件（即氣源系統(tǒng)、喂料裝置、管道部件和料氣分離裝置），采用負壓或是正壓設計，以期實現(xiàn)連續(xù)輸送或分批輸送等設計要求。設備在實際生產(chǎn)中的多變性要求氣力輸送設備廠商推陳出新，不斷改良進步。與此同時，也給設備產(chǎn)商們帶來了廣闊的市場前景。

Why equipment manufacturing has become the largest market for pneumatic conveying equipment purchasers, accounting for nearly 20% of the total market in 2019. Due to different practical needs, pneumatic conveying systems consist of different components (i.e. gas source system, feeding device, pipeline components, and material gas separation device), designed with negative or positive pressure to achieve design requirements such as continuous or batch conveying. The variability of equipment in actual production requires manufacturers of pneumatic conveying equipment to constantly innovate and improve. At the same time, it also brings broad market prospects to equipment manufacturers.

而源于氣力輸送密閉無污染、占地面積小、靈活自由、自動化程度高等優(yōu)點，氣力輸送也被用于多種其他行業(yè)。如非金屬礦、化工、食品，建材等行業(yè)，在2019年氣力輸送設備行業(yè)，分別占據(jù)市場份額10%、10%、8%、7%。隨著環(huán)保力度的加大、氣力輸送技術的進一步發(fā)展，預估在這些行業(yè)氣力輸送設備將占據(jù)更大的市場份額。

Due to its advantages of being sealed and pollution-free, occupying a small area, flexible and free, and highly automated, pneumatic conveying has also been used in various other industries. Industries such as non-metallic minerals, chemicals, food, and building materials held market shares of 10%, 10%, 8%, and 7% respectively in the pneumatic conveying equipment industry in 2019. With the increasing environmental protection efforts and further development of pneumatic conveying technology, it is estimated that pneumatic conveying equipment will occupy a larger market share in these industries.

氣力輸送按工作原理大致可分為吸送式與壓送式兩種類型。吸送式氣力輸送，是將大氣與物料一起吸入管道內(nèi)，用低氣壓力的氣流進行輸送。壓送式氣力輸送，是用高于大氣壓力的壓縮空氣推動物料進行輸送。

Pneumatic conveying can be roughly divided into two types based on its working principle: suction conveying and pressure conveying. Suction type pneumatic conveying is the process of sucking air and materials together into a pipeline and conveying them using low-pressure airflow. Pressure fed pneumatic conveying is the use of compressed air at a pressure higher than atmospheric pressure to push materials for transportation.

而數(shù)據(jù)顯示，市場并未偏愛某類氣力輸送裝置，負壓吸送類、真空類、壓送類各自占據(jù)著不同市場銷售額，未出現(xiàn)一家獨大的“壟斷”狀況。這一方面是由于不同輸送方式具備不同特點，適用于不同領域的不同要求；另一方面是由于中國產(chǎn)業(yè)鏈眾多，行業(yè)的生產(chǎn)集中度低，無法形成整合態(tài)勢。

However, the data shows that the market does not favor a certain type of pneumatic conveying device. Negative pressure suction, vacuum, and pressure conveying products each occupy different market sales, and there is no monopoly situation where one company dominates. On the one hand, this is because different conveying methods have different characteristics and are suitable for different requirements in different fields; On the other hand, due to the numerous industrial chains in China, the concentration of industry production is low, making it difficult to form an integrated situation.

在氣力輸送系統(tǒng)百花齊放的同時，氣力輸送系統(tǒng)的設備也逐漸走向精細化。一套完整的氣力輸送系統(tǒng)主要是由四大部分組成，分別為氣源系統(tǒng)、喂料裝置、管路系統(tǒng)以及料氣分離除塵設備。

Along with the flourishing of pneumatic conveying systems, the equipment of pneumatic conveying systems is gradually moving towards refinement. A complete pneumatic conveying system mainly consists of four parts, namely the gas source system, feeding device, pipeline system, and material gas separation and dust removal equipment.

輸送系統(tǒng)中設備的磨損和系統(tǒng)的可靠性問題在很大程度上影響著該輸送系統(tǒng)的經(jīng)濟性，這一點必須引起注意。不同系統(tǒng)由不同單元設備組成，部件的性能又分別影響各個系統(tǒng)的經(jīng)濟性能與實際運行的可靠性。

The wear and tear of equipment in the conveying system and the reliability of the system greatly affect the economy of the conveying system, which must be taken into account. Different systems are composed of different unit devices, and the performance of their components affects the economic performance and actual operational reliability of each system.

基于此，近年來氣力輸送設備對單部件的要求越來越高，在這一進程中不斷有優(yōu)秀、品質(zhì)可靠的氣力輸送單部件產(chǎn)品不斷涌現(xiàn)，如鼓風機、旋轉閥、管道連接件及壓送罐等。

Based on this, in recent years, the requirements for single components in pneumatic conveying equipment have become increasingly high. In this process, excellent and reliable pneumatic conveying single component products continue to emerge, such as blowers, rotary valves, pipeline connectors, and pressure feeding tanks.

近年來，國家對于環(huán)保的治理越來越重視，企業(yè)的粉塵污染逐漸被國家環(huán)保部門列為重點治理對象。由于氣力輸送完全密封的特性，物料不會逸散，使用物料氣力輸送系統(tǒng)能夠通過國家審核標準，加上物料氣力輸送的結構簡單，不易損壞、使用年限長，從而得到了更多企業(yè)的信賴與喜歡。希望我國氣力輸送技術越發(fā)進步，行業(yè)發(fā)展越發(fā)興盛。

In recent years, the government has attached increasing importance to environmental protection governance, and dust pollution from enterprises has gradually been listed as a key target of governance by the national environmental protection department. Due to the completely sealed characteristics of pneumatic conveying, materials will not escape. The use of material pneumatic conveying systems can pass national audit standards. In addition, the structure of material pneumatic conveying is simple, not easily damaged, and has a long service life, thus gaining the trust and favor of more enterprises. I hope that China's pneumatic conveying technology will continue to advance and the industry will develop more vigorously.
