通過通風改善車間的空氣環境。一方面，不符合衛生標準的污染空氣被排放到室外的局部場所或整個車間;另一方面，滿足衛生要求的新鮮空氣或凈化空氣進入室內區域。
　　Improve the air environment of the workshop by ventilation. On the one hand, the polluted air that does not meet the hygiene standard is discharged to the outdoor local place or the whole workshop; on the other hand, the fresh air or purified air that meets the hygiene requirements enters the indoor area.
　　在有害物質集中的地方設置捕集裝置，將有害物質排出，控制有害物質在室內的擴散。這種通風方法稱為局部排氣。這是更有效的通風防毒排塵方法。
　　A catching device shall be set up in the place where harmful substances are concentrated to discharge harmful substances and control the diffusion of harmful substances in the room. This ventilation method is called local exhaust. This is the most effective method of ventilation, gas prevention and dust removal.
　　局部排氣系統由以下部分組成:
　　The local exhaust system consists of the following parts:
　　(1)局部排氣罩
　　(1) Local exhaust hood
　　部分排氣罩用于捕獲有害物質。其性能的好壞直接影響到局部排氣系統的技術經濟指標。局部排氣罩具有良好的性能，如密封面，只要風量小即可獲得良好的工作效果。由于生產設備和操作的不同，排氣罩的形式也多種多樣。
　　Some exhaust hoods are used to catch harmful substances. Its performance directly affects the technical and economic indexes of the local exhaust system. Local exhaust hood has good performance, such as sealing surface, as long as the air volume is small, good working effect can be obtained. Due to the different production equipment and operation, there are various forms of exhaust hood.
　　(2)空氣管
　　(2) air pipe
　　在通風系統中輸送空氣的管道稱為風管。它們將系統的各種設備或組件連接成一個單元。為了提高系統的經濟性，應合理選擇風管內的氣流速度，管徑應短而直。風管通常由光滑的表面材料制成，如:薄鋼、PVC板，有時也用混凝土、磚等材料制成。
　　The ducts that carry air in the ventilation system are called ducts. They connect various devices or components of the system into a unit. In order to improve the economy of the system, the air velocity in the air duct should be reasonably selected, and the pipe diameter should be short and straight. Air ducts are usually made of smooth surface materials, such as thin steel, PVC board, and sometimes concrete, brick and other materials.

　　(3)除塵凈化設備
　　(3) Dust removal and purification equipment
　　為了防止空氣污染，當有害物質從空氣中排放超過排放標準時，必須經過凈化設備處理，達到排放標準后排放到大氣中。凈化設備分為除塵器和有害氣體凈化裝置兩類。
　　In order to prevent air pollution, when harmful substances are discharged from the air beyond the emission standard, they must be treated by purification equipment and discharged into the air after reaching the emission standard. The purification equipment is divided into dust remover and harmful gas purification device.
　　(4)風扇
　　(4) fan
　　風扇將空氣的力量輸送到機械排氣系統。為了防止風機的磨損和腐蝕，通常將其放置在清洗設備的后面。
　　The fan delivers the power of the air to the mechanical exhaust system. In order to prevent the abrasion and corrosion of the fan, it is usually placed behind the cleaning equipment.
　　若僅對局部地方進行排風或送風，即局部通風;如果整個車間通風或供應，它是完全通風。通常，根據通風系統的功能范圍不同，可分為局部通風、綜合通風和事故通風。局部通風系統可分為局部進風口和局部排氣兩大類。它們都利用當地的空氣流動，使當地的工作場所免受有害污染，創造良好的空氣環境
　　If only the local area is ventilated, that is, local ventilation; if the whole workshop is ventilated or supplied, it is fully ventilated. Generally, according to the different functional scope of ventilation system, it can be divided into local ventilation, comprehensive ventilation and emergency ventilation. Local ventilation system can be divided into local air inlet and local exhaust. They all use the local air flow to protect the local workplace from harmful pollution and create a good air environment
