良好的家庭生活環境對人們的身心健康是有很大的幫助的，現在，很多家庭住宅的廚房都是從家往外排煙的，對環境影響比較大，所以要求很多家庭安裝廚房排煙管道，這對廚房排煙有很大的幫助，但是在使用的時候有時會出現排煙不暢的問題，濟南排煙管道的種類是什么嗎?
A good family living environment is of great help to people's physical and mental health. Now, many family residential kitchens smoke from home, which has a greater impact on the environment. Therefore, many families are required to install kitchen smoke exhaust pipes, which is of great help to the kitchen smoke exhaust, but sometimes there will be problems of smoke exhaust when using What is a class?

煙道是住宅通風系統的重要部分，建設部1999年公布的《住宅設計規范》規范了煙道的設計。 但是，許多樓盤還存在無煙道設計的問題，小區住宅降煙、合味、交叉污染情況嚴重。
Flue is an important part of residential ventilation system. The design of flue is regulated by "residential design code" published by the Ministry of construction in 1999. However, there are many problems in the design of smoke-free road in many buildings. The smoke reduction, taste and cross pollution of residential buildings are serious.
一、廚房排煙管道不良的原因
1、 Causes of poor exhaust pipe in kitchen
根據《民用建筑設計通則》，煙道從屋頂出來的高度在0.6米以上。 但是，這個規定的執行情況也有不同的地方。 建設煙道的住宅設計的煙道類型單一，容易引起油煙的逆流、混色。 另外，有些樓盤為了擴大廚房面積，縮小垂直煙道的橫截面積，沒有機械排煙裝置，排煙系統流量小，排煙不好。
According to the general principles for design of civil buildings, the height of flue coming out of the roof is more than 0.6 meters. However, the implementation of this regulation is also different. The type of flue in residential design of building flue is single, which is easy to cause countercurrent and color mixing of lampblack. In addition, some buildings in order to expand the kitchen area, reduce the cross-sectional area of the vertical flue, there is no mechanical smoke exhaust device, smoke exhaust system flow is small, smoke exhaust is not good.

現在的住宅煙道分為單煙道式、主次式、變壓式、止回閥式。
Now residential flue is divided into single flue type, primary and secondary type, variable pressure type, check valve type.
1、單煙道式：由裝修簡單的矩形煙管構成，垂直橫穿各層住宅，各層住宅有連接抽油煙機的吸氣口，底層用一個補氣口補氣。 其原理是，各層的排煙被抽油煙機按壓，將油煙排出煙道，由于排煙溫度的作用，煙道產生上升浮力，從屋頂出來的吹出口排出排煙。
1. Single flue type: it is composed of rectangular smoke pipes with simple decoration, and it runs through the residence of each floor vertically. There is an air inlet connecting the range hood in each floor of the residence, and one air filling port is used for air supply at the bottom floor. The principle is that the smoke exhaust of each layer is pressed by the range hood to discharge the oil smoke out of the flue. Due to the effect of smoke exhaust temperature, the flue will produce upward buoyancy, and exhaust smoke from the vent coming out of the roof.
2、主次式：主次式煙道截面由兩個并列矩形煙管組成，垂直橫穿各層。 二次煙道在住宅的各層設置連接抽油煙機的吸氣口，二次煙道和主煙道離吸氣口以一定的距離合流，主煙道的底部有補風口。 其原理是通過抽油煙機將煙推入二次煙道，通過抽油煙機的推進力和油煙溫度上的浮力使油煙上升一段時間后進入從主煙道排出屋頂。
2. Primary and secondary type: the cross section of the primary and secondary flue is composed of two parallel rectangular flue pipes, which cross each layer vertically. The secondary flue is connected with the suction port of range hood in each floor of the residence. The secondary flue and the main flue converge at a certain distance from the suction port, and there is a supplementary air outlet at the bottom of the main flue. The principle is that the smoke is pushed into the secondary flue by the range hood, and the oil fume rises for a period of time by the propulsion force of the range hood and the buoyancy of the oil fume temperature, and then enters into the main flue and discharges to the roof.
3、變壓式：各層煙道為不同的截面形式，下層煙道通過主次煙道排氣，靠近屋頂的煙道像單煙道一樣起作用，將油煙直接排放到煙道中。 其目的是通過改變煙道的截面形式，利用煙氣流動的各種物理規律，保持氣流向上運動，有效地防止煙氣逆流和相互作用。
3. Variable pressure type: the flue of each layer has different cross-section. The lower flue exhausts through the primary and secondary flue, and the flue close to the roof acts like a single flue to directly discharge the oil fume into the flue. The purpose is to change the cross-section form of flue gas and make use of various physical laws of flue gas flow to keep the air flow upward and effectively prevent the reverse flow and interaction of flue gas. 上一篇：選擇山東通風管道的六大因素 看這里!
