一、系统网的布局形式

1、 Layout of system network

为方便管网的管理和运行调节，管网系统不宜过大，同一系统有多个分支管时，应将这些分支管分级控制，且同一系统的吸气点不宜过多，一定要注意各支管的压力平衡。常用的管网布局方式有干管配管、个别配管、环状配管3种。

In order to facilitate the management and operation adjustment of the pipe network, the pipe network system should not be too large. When there are multiple branch pipes in the same system, these branch pipes should be controlled hierarchically, and the suction points of the same system should not be too many. It is important to pay attention to the pressure balance of each branch pipe. There are three commonly used pipe network layout methods: main piping, individual piping, and annular piping.

二、布局的原则

2、 Principles of layout

1、通风管道安装系统的铺设原则

1. Laying principles of ventilation pipe installation system

管道铺设分明装、暗装，一般采用明装。因为明装以便于检修，在无法采用明装时考虑暗装方式，管道尽可能的集中成列，尽量沿墙或柱子平行铺设，若管径大或保温应布局在靠墙侧。一般两根管道平行布局时，间距不小于100～200mm。

The pipeline shall be laid in a clear and concealed manner, and generally installed in an open manner. Because open installation is convenient for maintenance, when it is not possible to use open installation, consider concealed installation. The pipes should be concentrated in rows as much as possible, and laid parallel to the wall or column as much as possible. If the pipe diameter is large or the insulation should be placed on the side against the wall. Generally, when two pipes are arranged in parallel, the spacing shall not be less than 100-200mm.

2、通风管道加工系统的连接原则

2. Connection principles for ventilation pipe processing systems

在以焊接为主要连接方式方法的管道中，应设置足够数量的法兰连接，在以螺纹为主的连接管道中应设置足够的活接头，以便宜于安装、拆卸、检修。

In pipelines where welding is the main connection method, a sufficient number of flange connections should be provided, and in threaded pipelines, sufficient unions should be provided to facilitate installation, disassembly, and maintenance.

3、通风管道加工系统的支撑原则管道不宜与阀件直接支撑在设备上，应单独设置支架或吊架，管道的焊缝位置应在施工方便或受力较小的地方，焊缝不得位于支架处且距离不小于200mm。

3. Support principle for the ventilation pipe processing system: The pipe should not be directly supported on the equipment with the valve. Instead, a separate bracket or hanger should be provided. The welding seam of the pipe should be located at a place where construction is convenient or the stress is small. The welding seam should not be located at the bracket and the distance should not be less than 200mm.

4、不同含尘气体性质不同，则净化的分段处理应不同。

4. Different dust containing gases have different properties, so the segmented treatment of purification should be different.

当污染源多时可以集中在一个净化系统中，也可分为几个系统，但出现污染物混合会引起燃烧、爆炸危险、不同温度和湿度的气体，混合后出现管道内结露、粉尘或气体性质不同，影响回收或净化效率的。

When there are many sources of pollution, they can be concentrated in a purification system or divided into several systems. However, mixing of pollutants can cause combustion, explosion hazards, and gases with different temperatures and humidity. After mixing, condensation in the pipeline, dust, or gases with different properties may occur, affecting recovery or purification efficiency.

5、通风管道加工系统布局中要保证整体系统的漏损小，确保吸尘口的有足够的风量。

5. In the layout of the ventilation pipe processing system, it is necessary to ensure that the leakage of the overall system is small and that there is sufficient air volume at the dust suction port.

6、通风管道加工系统布局要减小阻力。

6. The layout of the ventilation pipe processing system should reduce resistance.
