通风管道加工的体系布局需遵循以下几点：
The layout of ventilation pipeline processing system should follow the following points:
一、通风管道加工体系网的布局方式
I. Layout of Ventilation Pipeline Processing System Network
为便利管网的管理和运转调节，管网体系不宜过大，同一体系有多个分支管时，应将这些分支管分级操控，且同一体系的吸气点不宜过多，必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、单个配管、环状配管3种。
In order to facilitate the management and operation of the pipeline network, the pipeline network system should not be too large. When there are multiple branches in the same system, these branches should be operated at different levels, and the suction points of the same system should not be too many. The pressure balance of each branch must be paid attention to. There are three kinds of pipe network layout: main pipe distribution, single pipe distribution and ring pipe distribution.
二、通风管道加工体系布局的准则
2. Layout Criteria of Ventilation Pipeline Processing System
A、通风管道加工体系的铺设准则
A. Laying Criteria for Ventilation Pipeline Processing System
管道铺设清楚装、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，距离不小于100～200mm.
Pipeline laying is clear and concealed, which is usually done in open. Because it is easy to repair, when it is impossible to adopt open installation, concealed installation should be considered. Pipelines should be laid in rows as far as possible, parallel to walls or columns. If the diameter of pipes is large or insulation should be laid on the side of walls. Generally, when two pipelines are arranged in parallel, the distance is not less than 100-200 mm.
B、通风管道加工体系的衔接准则
B. Connection Criteria of Ventilation Pipeline Processing System
在以焊接为首要衔接方式方法的管道中，应设置满足数量的法兰衔接，在以螺纹为主的衔接管道中应设置满足的活接头，以便适宜装置、拆开、检修。
In the pipeline with welding as the primary connection method, flange joints should be set up to meet the number, and flexible joints should be set up in the pipeline with screw thread as the main connection method, so as to make suitable installation, disassembly and maintenance.
C、通风管道加工体系的支撑准则
C. Supporting Criteria of Ventilation Pipeline Processing System
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，管道的焊缝方位应在施工便利或受力较小的当地，焊缝不得位于支架处且距离不小于200mm.
Pipeline should not be directly supported on the equipment with valves. Support or hanger should be installed separately. Pipeline welding seam should be located in the place where construction is convenient or less stressed. Weld seam should not be located on the support and the distance is not less than 200 mm.
D、不同含尘气体性质不同，则净化的分段处理应不同。
D. If the properties of different dusty gases are different, the segmented treatment of purification should be different.
当污染源多时能够集中在一个净化体系中，也可分为几个体系，但呈现污染物混合会引起燃烧、爆破风险、不同温度和湿度的气体，混合后呈现管道内结露、粉尘或气体性质不同，影响回收或净化效率的。
When there are many pollution sources, they can be concentrated in one purification system or divided into several systems. However, the mixture of pollutants can cause combustion, explosion risk, different temperature and humidity of gas. After mixing, the condensation, dust or gas properties in pipelines are different, which affects the recovery or purification efficiency.
E、通风管道加工体系布局中要保证整体体系的漏损小，保证吸尘口的有满足的风量。
E. In the layout of the ventilation pipeline processing system, it is necessary to ensure that the leakage of the whole system is small and that the suction outlet has a satisfactory air flow.
F. The layout of ventilation pipeline processing system should reduce resistance.
