前的住宅烟道一般分为:单烟道式、主次式、变压式、止逆阀式。
The former residential chimney is generally divided into single flue type, primary and secondary type, variable pressure type and check valve type.
单烟道式:由一个简单的矩形烟管构成,垂直穿越各层住宅,在每层住宅中留有一个连接抽油烟机的进风口,底层由一个补风口补气。其原理是各层烟气在抽油烟机的推动下,将油烟排入烟道中,由于烟气温度的作用,在烟道中产生上升浮力,从出屋面的出风口将烟气排出。
Single flue type: consists of a simple rectangular pipe, vertical across the various floor of the house, in each floor of the house with a connection to the smoke pump air inlet, the bottom by a supplementary air vent. The principle is that the smoke of each layer is driven by the lampblack machine, and the lampblack is discharged into the flue. Because of the effect of the temperature of the flue gas, buoyancy is generated in the flue, and the smoke is discharged from the air outlet of the roof.

主次式:主次式烟道截面上由两个并列矩形烟管构成,垂直穿越各楼层。次烟道在住宅每层中设一连接排油烟机的进风口,次烟道与主烟道距进风口一定距离处相汇,主烟道底层有一补风口。其原理是通过抽油烟机将烟气推入次烟道中,用抽油烟机推动力和油烟温度上浮力使油烟上升一段距离后再进入主烟道排出屋面。
Primary and secondary type: the main and secondary flue section is made up of two parallel rectangular smoke pipes and runs vertically across each floor. The secondary flue is provided with an air inlet connecting the lampblack exhauster in each floor of the house. The secondary flue and the main flue meet at a certain distance from the air inlet, and a supplementary air inlet is arranged at the bottom of the main flue. The principle is that the smoke is pushed into the secondary flue by the lampblack machine, and the lampblack is driven by the lampblack machine and buoyed by the lampblack temperature for a certain distance before entering the main flue to discharge the roof.

变压式:将各层的烟道做成不同的截面形式,下层烟道通过主次烟道排气,而靠近屋面的烟道如同单烟道的作用,直接将油烟排入烟道排出。其目的是试图通过改变烟道的截面形式,利用烟气流动的各种物理规律,使气流保持向上的运动,最大程度防止烟气倒灌和互串。
Variable pressure type: the flue of each layer is made into different cross-section form, the lower flue is exhausted through the primary and secondary flue, and the flue near the roof is like a single flue, directly discharging lampblack into the flue. The purpose is to make use of the physical laws of flue gas flow to keep the air flow moving upward by changing the section form of flue gas, and to prevent flue gas backfilling and stringing each other to the greatest extent.

止逆阀式:止逆阀式烟道则是在单管烟道上的各层进风口处,加装一个兼有抽油烟机接口作用的复杂防气流逆行的止逆阀,迫使烟气向烟道单向运动,从而解决烟气互串的问题,但此种做法会轻度影响油烟机的排烟效果。
Check valve type: Check valve type flue is in the single-pipe flue at each layer of the air inlet, with a complicated anti-flow reverse check valve which has the function of the interface of the lampblack machine, forcing the flue gas to move one-way to the flue, thus solving the problem of flue gas string, but this practice will slightly affect the smoke exhaust effect of the lampblack machine.
