通风管道设计安装时要注意些什么问题?

通风管道设计不行忽视的三方面:

Three aspects should not be neglected in ventilation duct design:

1。系统的区别排烟系统防烟分区区别应结合建筑防火分区来考虑,做到既有利于地下室通风系统兼作排烟系统,又不会出现排烟风管跨越枋火分区现象。所以运用一套风管时系统应满足往常排风与火灾时排烟要求。

1. The distinction of smoke prevention zoning of smoke exhaust system should be considered in combination with building fire prevention zoning. It is beneficial to both basement ventilation system and smoke exhaust system, and there will be no phenomenon of smoke exhaust duct crossing the fire zoning. Therefore, when using a set of air ducts, the system should meet the usual requirements of ventilation and smoke exhaust in fire.

2.地下室通风方法合理安置排风管及排风口,往常排风用,火灾时兼作排烟风管及排烟口;地下一层考虑由车道天然进风,其它层由往常送风系统兼作火灾时补风系统。

2. The ventilation method of basement is reasonable to install exhaust ducts and vents, which are usually used as exhaust ducts and vents in fires; the natural intake of lanes is considered in the first floor of basement, and the supplementary air system in fires is used in the other layers.

每个排风、排烟及送风系统应设置竖井,进风口应设在地上洁净处,若能与地下主楼有必定间隔更好,其受火灾气影响会小;若能与地上主楼有必定间隔更好,其受火灾烟气影响会小,排风口方位应高于附楼层面, 以减少排风对地上环境影响。

Each exhaust, smoke exhaust and air supply system should be equipped with vertical shafts, and the air intake should be located in the ground clean place. If it has a certain interval with the underground main building, it will be less affected by fire gas; if it has a certain interval with the above-ground main building, it will be less affected by fire smoke, and the position of the air outlet should be higher than the level of the attached building, so as to reduce the influence of exhaust air on the ground environment.

3.排风、排烟及送风风机选型排风、排烟风机可选离心风机或许高温轴流风机。一般离心风机即可满足排风排烟要求,但大风量离心风机只能装置在地上,占地较大,需要较大机房。

3. Selection of exhaust fan, exhaust fan and supply fan, centrifugal fan or high temperature axial fan for exhaust fan. Generally, centrifugal fans can meet the requirements of exhaust and smoke exhaust, but large air volume centrifugal fans can only be installed on the ground, occupying a larger area, and need a larger machine room.

高温轴流风机为消防专用风机,也能满足在280℃ 烟温下运转30 min的要求, 而高温轴流风机体积小,一般可吊装,若设机房面积也小,实践工程设计中,往往选用高温轴流风机排烟。

High temperature axial flow fan is a special fan for fire fighting, which can also meet the requirement of running for 30 minutes at 280 ~C smoke temperature. However, high temperature axial flow fan is small in volume and can be hoisted generally. If the area of the room is small, high temperature axial flow fan is often used to exhaust smoke in practical engineering design.

通风管道装置的四大注意事项:

Four points for attention in ventilation pipeline installation:

1)关于比较复杂的民用建筑,在设计阶段,各工种(暖通、给水排水,供电照明与建筑专业)首先应洽谈好空间分隔,定出每种管道的标高范围。一般情况下不得越出给自己规则的边界。遇有单个管段要越界时应与其他工程洽谈。

1) For more complex civil buildings, at the design stage, each type of work (HVAC, water supply and drainage, power supply and lighting and architecture) should first negotiate space separation and determine the elevation range of each kind of pipeline. Normally, you should not go beyond the boundaries of your own rules. If there is a single pipe section to cross the boundary, it should be negotiated with other projects.

2)解决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) The criteria for solving the collision and coordination of various ventilation pipes are generally as follows: "Small pipes let big pipes, pressure let no pressure"。 For example, when a water pipe collides with an air pipe, the water pipe should turn。 When the cold and hot water pipes collide with the sewer pipes, the cold and hot water pipes should be changed。

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,将问题解决在装置之前。

3) Before the construction, the Engineer in charge of the equipment shall draw the pipelines of each type of work on a single plan. Each pipe uses a colour pen. Summarize the elevation at each intersection to see if there is any contradiction, find out in time, and solve the problem before the device.

4)为了减少出资,节约空间,降低层高,有些敷设无坡度要求的管道,可以穿梁敷设(如自来水管道,消防喷洒干管等)。

4) In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams (such as tap water pipes, fire spraying trunk pipes, etc。)。
