通風管道是生活中不可缺少的設備，那么今天就一起了解一下通風管道必須遵守哪些布局原則吧？

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

　　濟南通風管道處理的系統布置應符合以下幾點：

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

　　一、系統網絡布局方法

　　I. system network layout method

　　為了便于管網的管理和運行，管網系統不宜過大。當同一系統中有多個分支時，分支應分級操作，同一系統的吸入點不宜過多。要注意各支管的壓力平衡。管網的布置方式有三種：主管、單管和環管。

　　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。布局原則

　　Two. Layout principle

　　1。通風管道安裝系統敷設標準

　　1。 Standard for laying of ventilation pipe installation system

　　管道安裝應明裝暗裝，一般選用明裝。由于明裝便于維護，當不能選擇明裝時，應考慮暗裝方式。管道應盡可能成排布置，并盡可能平行于墻或柱敷設。如果管徑較大或保溫布置在墻邊。一般兩條管道平行布置時，間距不應小于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。通風管道處理系統連接標準

　　2. Standard for connection of ventilation duct processing system

　　以焊接為主要連接方式的管道，應設置若干法蘭接頭，以螺紋為主要連接方式的管道，應設置活動接頭，以便于安裝、拆卸和維修。

　　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。通風管道處理系統的支撐標準不應直接支撐在帶閥門的設備上，應單獨設置支吊架。管道的焊接位置應在施工方便或應力小的地方，焊縫不應位于支架處，間距不應小于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。如果不同含塵氣體性質不同，分段凈化處理應不同。

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

　　當污染源較多時，可以集中在一個凈化系統中，也可以分成幾個系統。但污染物的混合會引起燃燒、爆炸危險、不同溫濕度的氣體。混合后，管道內的冷凝、粉塵或氣體性質會有所不同，這會影響回收或凈化效率。

　　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。在通風管道處理系統的布置中，要保證各系統漏風量小，集塵器風量充足。

　　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。通風管道處理系統的布置應減少阻力。

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