        濟南通風管道是怎么實現局部排風的?

        來源:http://www.boursomarket.com 日期:2019-08-20 發布人:admin

          在一些有害物質集中的地方,建立了有害物質的收集和清除裝置,控制有害物質在室內的擴散。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 some places where harmful substances are concentrated, devices for collecting and removing harmful substances have been set up to control the indoor diffusion of harmful substances. This type of ventilation is called local exhaust. This is the most effective way of ventilating gas and dust.
          濟南部分消防排煙管道由以下部分組成:
          Some fire fighting and smoke exhaust pipes in Jinan are composed of the following parts:
          1)部分排氣罩
          1) Partial exhaust hood
          排氣罩的一部分用來捕捉害蟲。其性能直接影響到某些排氣系統的技術經濟指標。排風罩性能好的部件,如閉式排風罩,只需少量的空氣即可獲得良好的工作效果。由于不同的消耗設備和操作方式,排氣罩有多種方式。
          Part of the exhaust hood is used to catch pests. Its performance directly affects the technical and economic indicators of some exhaust systems. The components with good performance of exhaust hood, such as closed exhaust hood, need only a small amount of air to achieve good working effect. Due to different consumption equipment and operation mode, exhaust hood has many ways.
          2)管道
          2) Pipeline
          在通風系統中,輸送空氣的管道稱為風管。它們將系統中的各種設備或組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。風管通常由外部潤滑的材料制成,如:薄鋼板、PVC板,有時還有混凝土、磚等材料。
          In the ventilation system, the air duct is called the air duct. They connect 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 externally lubricated materials, such as thin steel plate, PVC board, and sometimes concrete, brick and other materials.

          3)除塵凈化設備
          3) Dust removal and purification equipment
          為了避免空氣污染,當有害物質排放到空氣中的量超過排放標準時,必須用凈化設備進行處理,當達到排放標準時,將其排放到大氣中。凈化設備可分為除塵器和有害氣體凈化裝置。
          In order to avoid air pollution, when the amount of harmful substances discharged into the air exceeds the discharge standard, it must be treated with purification equipment, and when the discharge standard is reached, it will be discharged into the atmosphere. Purification equipment can be divided into dust collector and harmful gas purification device.
          4)風扇
          4) Fans
          風扇捕捉空氣運動到機械排氣系統的動力。為避免風機磨損和腐蝕,通常將風機置于清洗設備的后方。
          The fan captures the power of the air moving to the mechanical exhaust system. In order to avoid wear and corrosion of the fan, the fan is usually placed behind the cleaning equipment.
          局部通風僅當局部通風或送風停止時;如果整個車間的排風或送風停止,應充分通風。一般根據通風系統運行范圍的不同,可將通風分為局部通風、全通風和事故通風。部分通風系統分為進氣部分和排氣部分兩大類,它們都是部分氣流的應用,部分工作場所受到有害污染,形成良好的空氣環境。
          Local ventilation is only when the local ventilation or air supply stops; if the exhaust or air supply stops in the whole workshop, it should be fully ventilated. Generally, according to the different operating range of ventilation system, ventilation can be divided into local ventilation, full ventilation and accident ventilation. Part of the ventilation system is divided into two categories: intake part and exhaust part. They are all part of the application of air flow. Some workplaces are harmfully polluted and form a good air environment.
