        局部排氣系統由什么來組成的?

          隨著工業化、城鎮化的不斷推進,各行業通風管道的揚塵和污物壓力不斷增大,增加了通風管道清洗工作的壓力。那么,濟南通風管道應該如何清洗呢?通風管道的清洗過程主要包括以下幾個方面。
          With the continuous advancement of industrialization and urbanization, the dust and dirt pressure of ventilation pipelines in various industries is increasing, which increases the pressure of ventilation pipeline cleaning. Then, how should Jinan ventilation pipeline be cleaned? The cleaning process of ventilation pipeline mainly includes the following aspects.
          一是對設備進行大修,清洗風管及進風口,檢查風管連接是否可靠;閥門泄漏等。
          One is to overhaul the equipment, clean the air duct and air intake, check whether the air duct connection is reliable, valve leakage, etc.
          第二段清洗通風管道,清洗風機和進風口。在風管清洗過程中,嚴禁操作人員進入風管進行清洗工作。應使用清洗設備,有效地將管道內可見污染物輸送到指定設備。
          The second section cleans the ventilation duct, the fan and the air inlet. In the process of duct cleaning, operators are strictly forbidden to enter the duct for cleaning. Professional cleaning equipment should be used to effectively transport visible pollutants in pipelines to designated equipment.
          后,清洗工作完成后,將拆卸的風口重新安裝,注意管路的連接性,調整出氣量;同時檢查設備質量和通風道整體連接情況,確保通風道正常工作。還要注意制作詳細的清洗記錄,以便日常設備維護和下一步的清洗工作。
          Finally, after the cleaning work is completed, the dismantled air outlets are re-installed, the connection of pipelines is noticed, and the air output is adjusted. At the same time, the quality of equipment and the overall connection of ventilation ducts are checked to ensure the normal operation of ventilation ducts. Also pay attention to the production of detailed cleaning records, in order to daily equipment maintenance and next cleaning work.
          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濁空氣被排放到室外局部場所或整個車間;另一方面,新鮮空氣或凈化后符合衛生要求的空氣進入房間。我們把前者稱為排氣,后者稱為進氣。
          Improve the air environment of the workshop by ventilation. On the one hand, the polluted air which does not meet the hygienic standards is discharged into the outdoor local places or the whole workshop; on the other hand, fresh air or purified air which meets the hygienic requirements enters the room. We call the former exhaust and the latter intake.
          濟南局部通風管道中有害物質聚集的地方,設置了捕集器,清除有害物質,控制有害物質進入室內的擴散。這種通風方式稱為局部排風。這是有效的氣體和灰塵的通風方式。
          In Jinan, where harmful substances accumulate in local ventilation pipelines, traps are set up to remove harmful substances and control the diffusion of harmful substances into indoors. This type of ventilation is called local exhaust. This is the most effective way of ventilating gas and dust.
          局部排氣系統由以下部分組成:
          The local exhaust system consists of the following parts:
          (1)部分排氣罩
          (1) Partial exhaust hood
          部分排氣罩用于捕捉害蟲。其性能直接影響到局部排氣系統的技術經濟指標。局部排風罩性能好,如閉式排風罩,只要風量小,就能取得良好的工作效果。由于生產設備和操作的不同,排風罩的類型也不盡相同。
          Part of the exhaust hood is used to catch pests. Its performance directly affects the technical and economic indicators of local exhaust system. Local exhaust hood has good performance, such as closed exhaust hood, as long as the air volume is small, it can achieve good results. Due to the different production equipment and operation, the types of exhaust hood are different.
          (2)管道
          (2) Pipeline
          在通風系統中輸送氣體的管道稱為風管。它們將系統中的各種設備或部件作為一個整體連接起來。為了提高系統的經濟性,應合理選擇管道內的氣速,管道應短而直。風管通常由表面光滑的材料制成,如鋼板、PVC板,有時還有混凝土、磚等。

          The pipeline that conveys gas in the ventilation system is called air duct. They connect the various devices or components in the system as a whole. In order to improve the economy of the system, the gas velocity in the pipeline should be reasonably selected, and the pipeline should be short and straight. Air ducts are usually made of smooth surface materials, such as steel plate, PVC board, and sometimes concrete, brick, etc.
          (3)除塵凈化設備
          (3) Dust removal and purification equipment
          為了防止空氣污染,當排放的空氣中有害物質超過排放標準時,必須使用凈化設備進行處理。在達到排放標準后,它將被排放到大氣中。凈化設備分為除塵器和有害氣體凈化裝置。
          In order to prevent air pollution, when the harmful substances discharged in the air exceed the emission standards, it is necessary to use purification equipment for treatment. After meeting the emission standards, it will be discharged into the atmosphere. Purification equipment is divided into dust collector and harmful gas purification device.
          (4)風扇
          (4) Fans
          濟南通風道風機以機械排風系統捕捉氣流的動力。為了防止風機磨損和腐蝕,通常將其放置在清洗設備的后面。
          Jinan ventilation duct fan captures the power of air flow with mechanical exhaust system. In order to prevent the fan from wearing and corrosion, it is usually placed behind the cleaning equipment.
          如只在局部地方進行排風或送風,即局部通風;如果在整個車間進行排氣或送風,則應充分通風。一般根據通風系統功能范圍的不同,可將通風分為局部通風、綜合通風和事故通風。局部通風系統分為局部進風和局部排風兩大類。他們都使用當地的氣流,使當地的工作場所免受有害物質的污染,創造一個良好的空氣環境。
          If only exhaust or supply air in local areas, that is, local ventilation; if exhaust or supply air in the whole workshop, it should be fully ventilated. Generally, according to the different functional range of ventilation system, ventilation can be divided into local ventilation, comprehensive ventilation and accident ventilation. Local ventilation system can be divided into two categories: local intake and local exhaust. They all use local airflow to protect local workplaces from harmful substances and create a good air environment.
