通风管道是通风体系重要组成部分,通风管道设备体系设计目的,是要合理地处理安排空气的活动,在确保使用作用前提下,合理断定风管结构、布局和尺寸,使体系的初投资和运用费用归纳较低。通风工程是送风、排风、除尘以及排烟体系工程统称。

The ventilation pipe is an important part of the ventilation system, ventilation system design of pipeline equipment, is to reasonably arrange the air handling activities, in ensuring the use function under the premise of reasonable structure, determine the layout and size of the wind pipe, so that the system's initial investment and operation expenses of the low induction. Ventilation engineering is air, exhaust, dust and smoke exhaust system works collectively.

合理的通风体系能够确保作业场所空气活动循环,还能够给工人一个较为舒适的呼吸环境。通风管道设备体系设计问题如下:

The ventilation system can ensure the reasonable workplace air circulation, also can give workers a more comfortable breathing environment. The design problem of ventilation system of pipeline equipment:

榜首,气流安排:通风工程气流安排基本准则是排风口应尽量接近有害物源或散热设备,送风口应尽量的接近操作地点或人员经常停留处。

The top air ventilation engineering flow arrangement arrangement: the basic criterion is the outlet should be as close as possible to the source of harmful substances or cooling equipment, the outlet should be as close to the operation place or people often stay at。

第二,风机选型:依据风机特性曲线能够看出,风机能够在各种不同风量下作业,风机在特性曲线某一作业点上,风机的风压和体系中的压力得到平衡,就断定体系的风量。

Second, fan selection: Based on the characteristic curve of the fan can be seen, the fan can work in a variety of different air flow, the fan at a point of operation characteristic curve, fan wind pressure and system pressure balance, conclude that the air volume system.

第三,防火阀设置:设置防火阀的首要目的是避免火灾经过风管漫延。引荐采用将卫生间的排气支管接入排气竖井上升六十毫米的“避免回流”措施。

Third, the fire valve setting: the primary purpose of setting fire valve is to avoid the fire spread through the wind pipe。 The referral will avoid return measures to toilet exhaust pipe access exhaust shaft sixty mm rise "。

其具有结构简单,造价低、运转可靠等特点,因为采用了弯头进竖井,支管和主管气流方向相同,此部分部分的助力小,其竖井排风的总阻力并不一定因为竖井面积减少以点而增大。

It has the advantages of simple structure, low cost, reliable operation and other characteristics, because the use of elbow into shaft, branch and charge flow direction, this part of the small power, the total resistance of the shaft exhaust is not necessarily because the area is reduced to increase the shaft.

装置四大注意事项;

Unit four note;

1)对于比较复杂的民用修建,在设计阶段,各工种(暖通、给水排水,供电照明与修建专业)首先应洽谈好空间分隔,定出每种管道的标高规模。一般情况下不得越出给自己规则的边界,遇有个别管段要越界时应与其他工程洽谈。

1) for civil building complex, in the design stage, various types (HVAC, water supply and drainage, power supply and construction of professional lighting) should first negotiate good space, set the size of each pipeline elevation. Can not go beyond the boundary to their own rules in general, in a period of leave to cross should negotiate with other engineering.

2)处理各种通风管道相碰及协调的准则,一般为:“小管让大管,有压让无压”。例如,自来水管与风管相撞,则应当自来水管拐弯。冷、热水管与下水管相碰,则应改变冷、热水管道。

2) all kinds of ventilation pipe and collision coordination criteria for general treatment: "let the pressure get tubular bassoon, no pressure". For example, tap water pipe and air pipe collided, should turn the tap water pipe. The cold and hot water pipes and water pipes together, should change the cold and hot water pipe.

3)施工前应设备总管的工程师,将各工种的管线,单线画在一张平面图上。每种管道用一种彩色笔。在各交点处归纳其标高,看是否有矛盾之处,及时发现,将问题处理在装置之前。

3) equipment duct Engineer shall before the construction of the pipeline will be of various types, single picture on a graph。 A color pen for each kind of pipeline。 At each intersection point induces its elevation, to see if there are contradictions, in time, will deal with the problem in the prior device。

4)为了减少投资,节省空间,降低层高,有些敷设无坡度要求的管道,能够穿梁敷设(如自来水管道,消防喷洒干管等)。

4) in order to reduce investment, save space, reduce the floor height, some non laying pipeline slope requirements, can cross beam placement (such as tap water pipelines, fire sprinkler pipe etc.).
