通风管道布局装置都需要遵守哪些原则?

发布人:   发布时间:2019-12-18 13:08:42

通风管道是生活中不可缺少的设备,那么今天就一起了解一下通风管道必须遵守哪些布局原则吧?

  Ventilation duct is an indispensable equipment in life, so let's understand what layout principles must be followed for ventilation duct today?

  济南通风管道处理的系统布置应符合以下几点:

  The system layout of Jinan ventilation pipeline treatment shall comply with the following points:

  一、系统网络布局方法

  I. system network layout method

  为了便于管网的管理和运行,管网系统不宜过大。当同一系统中有多个分支时,分支应分级操作,同一系统的吸入点不宜过多。要注意各支管的压力平衡。管网的布置方式有三种:主管、单管和环管。

  In order to facilitate the management and operation of the pipe network, the pipe network system should not be too large. When there are multiple branches in the same system, the branches should be operated in different levels, and the suction points of the same system should not be too many. Pay attention to the pressure balance of each branch pipe. There are three types of pipe network layout: main pipe, single pipe and ring pipe.

  二。布局原则

  Two. Layout principle

  1。通风管道安装系统敷设标准

  1。 Standard for laying of ventilation pipe installation system

  管道安装应明装暗装,一般选用明装。由于明装便于维护,当不能选择明装时,应考虑暗装方式。管道应尽可能成排布置,并尽可能平行于墙或柱敷设。如果管径较大或保温布置在墙边。一般两条管道平行布置时,间距不应小于100-200mm。

  The pipeline shall be installed in an open and concealed way, and generally in an open way. Because the open installation is easy to maintain, when the open installation cannot be selected, the concealed installation mode shall be considered. Pipes shall be arranged in rows as far as possible and laid parallel to walls or columns as far as possible. If the pipe diameter is large or the thermal insulation is arranged beside the wall. Generally, when two pipelines are arranged in parallel, the spacing shall not be less than 100-200mm.

  2。通风管道处理系统连接标准

  2. Standard for connection of ventilation duct processing system

  以焊接为主要连接方式的管道,应设置若干法兰接头,以螺纹为主要连接方式的管道,应设置活动接头,以便于安装、拆卸和维修。

  For pipes with welding as the main connection mode, several flange joints shall be set, and for pipes with thread as the main connection mode, movable joints shall be set to facilitate installation, disassembly and maintenance.

  3。通风管道处理系统的支撑标准不应直接支撑在带阀门的设备上,应单独设置支吊架。管道的焊接位置应在施工方便或应力小的地方,焊缝不应位于支架处,间距不应小于200mm。

  3。 The support standard of the ventilation pipe processing system shall not be directly supported on the equipment with valve, and the support and hanger shall be set separately. The welding position of the pipeline shall be at the place where the construction is convenient or the stress is small. The welding seam shall not be located at the support and the spacing shall not be less than 200mm.

  4。如果不同含尘气体性质不同,分段净化处理应不同。

  4。 If the properties of different dust containing gases are different, the purification treatment by stages should be different.

  当污染源较多时,可以集中在一个净化系统中,也可以分成几个系统。但污染物的混合会引起燃烧、爆炸危险、不同温湿度的气体。混合后,管道内的冷凝、粉尘或气体性质会有所不同,这会影响回收或净化效率。

  When there are many pollution sources, they can be concentrated in one purification system or divided into several systems. However, the mixture of pollutants will cause combustion, explosion hazard and gases with different temperature and humidity. After mixing, the condensation, dust or gas properties in the pipeline will be different, which will affect the recovery or purification efficiency.

  5。在通风管道处理系统的布置中,要保证各系统漏风量小,集尘器风量充足。

  5。 In the layout of the ventilation pipe processing system, it is necessary to ensure that the air leakage of each system is small and the air volume of the dust collector is sufficient.

  6。通风管道处理系统的布置应减少阻力。

  6。 The arrangement of the duct handling system shall reduce resistance.
