通風(fēng)管道是工業(yè)與民用建筑的通風(fēng)與空調(diào)工程用金屬或非金屬管道，是為了使空氣流通，降低有害氣體濃度的一種市政基礎(chǔ)設(shè)施。對(duì)于比較復(fù)雜的民用建筑，在設(shè)計(jì)階段，各工種暖通、給水排水，供電照明與建筑應(yīng)協(xié)商好空間分隔，定出每種管道的標(biāo)高范圍。一般情況下不得越出給自己規(guī)定的界限。遇有個(gè)別管段要越界時(shí)應(yīng)與其他工程協(xié)商。

Ventilation pipe is a metal or nonmetal pipe for ventilation and air conditioning engineering in industrial and civil buildings. It is a municipal infrastructure for making air circulation and reducing harmful gas concentration. For more complex civil buildings, at the design stage, all kinds of HVAC, water supply and drainage, power supply lighting and building should first negotiate space separation and determine the elevation range of each pipeline. The general case not set himself beyond the boundaries. In case there is a separate section to cross the boundary, we should negotiate with other projects.

解決各種通風(fēng)管道相碰及協(xié)調(diào)的原則，一般為：“小管讓大管，有壓讓無壓”。例如，自來水管與風(fēng)管相撞，則應(yīng)當(dāng)自來水管拐彎。冷、熱水管與下水管相碰，則應(yīng)改變冷、熱水管道。

To solve all kinds of ventilation pipe collide and coordination principle, generally: "let the pressure get tubular bassoon, no pressure". For example, the water pipe and the wind pipe collide, then the tap water pipe should be turned. The cold and hot water pipes and water pipes together, should change the cold and hot water pipe.

通風(fēng)管道施工前應(yīng)設(shè)備總管的工程師，將各工種的管線，單線畫在一張平面圖上。每種管道用一種彩色筆。在各交點(diǎn)處綜合其標(biāo)高，看是否有矛盾之處，及時(shí)發(fā)現(xiàn)，將問題解決在安裝之前。為了減少投資，節(jié)省空間，降低層高，有些敷設(shè)無坡度要求的管道，可以穿梁敷設(shè)。

Before the construction of a ventilation pipe, the engineer of the general pipe of the equipment shall draw the lines of the various types of work and the single line on a plane map. Each type of pipe is used with a color pen. In each point of the intersection of its elevation, see if there is any contradiction, timely discovery, the problem is solved before the installation. In order to reduce investment, save space and reduce the height of layers, some pipes that are laid without slope can be laid by beams.

做好工業(yè)通風(fēng)工作，一方面能夠改善生產(chǎn)車間及周圍的空氣條件，防止職業(yè)病的產(chǎn)生、保護(hù)人民健康、提高勞動(dòng)生產(chǎn)率；

Doing well in industrial ventilation can improve the air condition of production workshop and surrounding area, prevent occupational disease, protect people's health and increase labour productivity.

另一方面可以保證生產(chǎn)正常運(yùn)行，提高產(chǎn)品質(zhì)量。隨著工業(yè)的不斷發(fā)展，散發(fā)的工業(yè)有害物的種類和數(shù)量日益增加，大氣污染已經(jīng)成為了一個(gè)全球性的問題。如何做好工業(yè)通風(fēng)，職業(yè)安全健康管理以及環(huán)境保護(hù)是我們安全工作人員的意向重要職責(zé)。通過本周的工業(yè)通風(fēng)與除塵大作業(yè)的學(xué)習(xí)，學(xué)會(huì)通風(fēng)管道系統(tǒng)的設(shè)計(jì)計(jì)算，了解通風(fēng)管道系統(tǒng)包括通風(fēng)除塵管道、空調(diào)管道等，是通風(fēng)除塵和空氣調(diào)節(jié)系統(tǒng)的重要組成部分，它把通風(fēng)進(jìn)風(fēng)口，空氣的熱濕及凈化處理設(shè)備，送排風(fēng)口，部件和風(fēng)機(jī)連成一個(gè)整體，使之有效運(yùn)轉(zhuǎn)。

On the other hand, it can ensure the normal operation of the production and improve the quality of the product. With the continuous development of industry, the variety and quantity of industrial hazardous materials are increasing, and air pollution has become a global problem. How to do a good job of industrial ventilation, occupational safety and health management and environmental protection is an important duty of our safety staff. Through this week's industrial ventilation work study, design and calculation to ventilation system, ventilation system including understanding ventilation duct, air duct, is an important part of ventilation and air conditioning systems, the ventilation air inlet, air heat and moisture and purification equipment, supply and exhaust the air blower, and parts into a whole, and make it work efficiently.
