    住宅通风系统的问题以及种类!

      排烟管道是住宅通风系统的重要组成部分。但许多建筑仍存在不排放烟气管道设计的问题,居住区倒烟、气味、交叉污染严重。

      Smoke exhaust pipe is an important part of residential ventilation system. However, many buildings still have problems in the design of non-emission flue gas pipelines. The smoke, odor and cross-contamination in residential areas are serious.

      首先,了解住宅排烟管道的分类

      First, understand the classification of smoke exhaust pipes in residential buildings

      目前住宅排烟管一般分为:单排管式、一次和二次式、变压式、止回阀式。

      At present, smoke exhaust pipes in residential buildings are generally divided into single row, primary and secondary, variable pressure and check valve.

      止回阀类型:止回阀类型排气管在单管排烟管层FengKouChu,配备复杂的组合抽油烟机接口函数反空气逆止回阀,被迫吸烟烟气管道的单向运动,以解决烟气混合的问题,但它会稍微影响抽油烟机的效果。

      Check Valve Type: Check Valve Type Exhaust Pipe in FengKouChu single-pipe smoke exhaust pipe layer, equipped with complex combination smoke machine interface function anti-air check valve, forced to smoke one-way movement of smoke pipe to solve the problem of smoke mixing, but it will slightly affect the effect of smoke machine.

      一、二级烟管:一、二级烟管段由两条平行的矩形烟管组成,垂直穿过每层楼。在房屋的每一层设置二次排烟管,连接排烟机的进风口。二次排烟管和主排烟管位于距进风口一定距离处。主排烟管底部有辅助出风口。其原理是通过排烟机将排烟推进到二排排烟管中,利用排烟机的推进和排烟温度上的浮力使排烟管进入主排烟管排出屋面一段距离后再次上升。

      First and second class smoke pipes: First and second class smoke pipes are composed of two parallel rectangular smoke pipes, which pass through each floor vertically. A secondary smoke exhaust pipe is arranged on each floor of the house to connect the air inlet of the smoke exhauster. The secondary exhaust pipe and the main exhaust pipe are located at a certain distance from the air intake. There is an auxiliary outlet at the bottom of the main exhaust pipe. The principle is that the exhaust pipe is pushed into the second exhaust pipe by the exhaust machine, and then rises again after the exhaust pipe enters the main exhaust pipe and discharges a certain distance from the roof by the propulsion of the exhaust machine and the buoyancy of the exhaust temperature.

      改变压力类型:将每一层排烟管不同的截面形式,较低的层排烟管通过初级和二级排气烟管排气,和排气烟管附近的屋顶作为一个单一的排烟管,直接排烟排烟管放电。其目的是改变烟气管道的截面,利用烟气流动的各种物理规律,保持气流向上运动,最大限度地防止烟气回流和相互聚集。

      Change the pressure type: each layer of exhaust pipe has different cross-sectional form, the lower layer of exhaust pipe exhaust through primary and secondary exhaust pipe, and the roof near the exhaust pipe as a single exhaust pipe, direct discharge of exhaust pipe. Its purpose is to change the cross section of flue gas pipeline, make use of the various physical laws of flue gas flow, keep the airflow moving upward, and prevent the backflow and mutual accumulation of flue gas to the greatest extent.

      单排排烟管类型:由一个简单的矩形排烟管,垂直穿过房屋的每一层,在房屋的每一层都有一个连接到排烟罩进风口,底部由一个进风口进气。其原理是将抽油烟机的每层烟气推到抽油烟机的下方,将抽油烟排进排烟管道,由于烟气温度的作用,排烟管道产生上升浮力,从屋顶的出口将烟气排出。

      Single row smoke exhaust pipe type: a simple rectangular smoke exhaust pipe, vertical through each floor of the house, in each floor of the house there is a connection to the exhaust hood air intake, the bottom of an air intake. The principle is to push each layer of smoke from the hood to the lower part of the hood and exhaust the smoke into the smoke exhaust pipe. Because of the effect of the temperature of the smoke, the smoke exhaust pipe produces rising buoyancy, and the smoke is discharged from the outlet of the roof.

      2. 排烟管不自由的原因

      2. Reasons for the non-freedom of smoke exhaust pipe

      根据民用建筑设计的一般规则,从屋顶伸出的烟管高度不小于0.6m。但在一些地方,这些规定的执行情况各不相同。有些住宅设计的排烟管管型比较单一,容易引起烟气倒流、异味。另外,一些建筑盘增加了厨房面积,减少了垂直排烟管道的横截面积,而且没有机械排烟装置,向下排烟系统流量很小,造成排烟不畅。

      According to the general rules of civil architecture design, the smoke pipe from the roof is not less than 0.6m in height. However, in some places, the implementation of these Provisions varies. Some residential design smoke exhaust pipe type is relatively single, easy to cause smoke backflow, odor. In addition, some building pans increase the kitchen area, reduce the cross-sectional area of the vertical smoke exhaust pipe, and there is no mechanical smoke exhaust device, the flow of downward smoke exhaust system is very small, resulting in poor smoke exhaust.
