通風管道加工的體系布局需遵循以下幾點：
The layout of ventilation pipeline processing system should follow the following points:
一、通風管道加工體系網的布局方式
I. Layout of Ventilation Pipeline Processing System Network
為便利管網的管理和運轉調節，管網體系不宜過大，同一體系有多個分支管時，應將這些分支管分級操控，且同一體系的吸氣點不宜過多，必定要注意各支管的壓力平衡。常用的管網布局方式有干管配管、單個配管、環狀配管3種。
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、通風管道加工體系布局的準則
2. Layout Criteria of Ventilation Pipeline Processing System
A、通風管道加工體系的鋪設準則
A. Laying Criteria for Ventilation Pipeline Processing System
管道鋪設清楚裝、暗裝，一般采用明裝。因為明裝以便于檢修，在無法采用明裝時考慮暗裝方式，管道盡可能的集中成列，盡量沿墻或柱子平行鋪設，若管徑大或保溫應布局在靠墻側。一般兩根管道平行布局時，距離不小于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、通風管道加工體系的銜接準則
B. Connection Criteria of Ventilation Pipeline Processing System
在以焊接為首要銜接方式方法的管道中，應設置滿足數量的法蘭銜接，在以螺紋為主的銜接管道中應設置滿足的活接頭，以便適宜裝置、拆開、檢修。
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、通風管道加工體系的支撐準則
C. Supporting Criteria of Ventilation Pipeline Processing System
管道不宜與閥件直接支撐在設備上，應單獨設置支架或吊架，管道的焊縫方位應在施工便利或受力較小的當地，焊縫不得位于支架處且距離不小于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、不同含塵氣體性質不同，則凈化的分段處理應不同。
D. If the properties of different dusty gases are different, the segmented treatment of purification should be different.
當污染源多時能夠集中在一個凈化體系中，也可分為幾個體系，但呈現污染物混合會引起燃燒、爆破風險、不同溫度和濕度的氣體，混合后呈現管道內結露、粉塵或氣體性質不同，影響回收或凈化效率的。
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、通風管道加工體系布局中要保證整體體系的漏損小，保證吸塵口的有滿足的風量。
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.
