在小室内空间里打造耐用美丽的家庭厨房，让室内空间看上去不拥堵，让厨柜够个性化，全体化感觉够时尚，在方寸之地更好地依托各式各样厨具设备，以抵达别有洞天、物我融洽的实际作用，需要动动脑筋。为了便于风道就位，一般多采用将风道吊在脚手架上，然后再将其抬放在风道支架上的方法。脚手架应沿其风道长度方向搭设，高度和位置应适合施工操作，吊装顺序应先干管后支、立管，吊起时，吊点应牢固，两吊点应均匀受力。垂直风管可采用人工和大绳辅助就位。调整风管保证垂直度要求。

To create a durable and beautiful home kitchen in a small indoor space, make the indoor space look free of congestion, make the kitchen cabinets personalized and fashionable. To better rely on all kinds of kitchen appliances and equipment in a small space to achieve the practical role of unique and harmonious things, we need to use our brains. In order to facilitate the positioning of the air duct, the method of hoisting the air duct on the scaffold and then lifting it on the air duct support is generally adopted. The scaffold shall be erected along the length of the air duct, and the height and position shall be suitable for the construction operation. The hoisting sequence shall be from the main pipe to the branch and riser. When hoisting, the lifting points shall be firm, and the two lifting points shall be uniformly stressed. The vertical air duct can be placed manually and with the help of large ropes. Adjust the air duct to ensure the perpendicularity requirements.

通风管道的制做安装对气体流通效果影响非常大，因此当通风管道安装后，一定要开展品质验收。管路吊装前要查验所有支撑架的平整度和设计标高，查验支撑架的坚固水平，通风风管吊装可选用立即和吊装工具二种方式。对通风风管横断面较小，又部位较低的，可选用人工服务吊装法，只需架设简单钢管脚手架只能。当通风管道横断面很大且管道较长时，可选用动滑轮、倒链、大绳等方式起吊。

The manufacture and installation of ventilation pipes have a great impact on the gas flow effect, so after the installation of ventilation pipes, quality acceptance must be carried out. Before the pipeline hoisting, check the flatness and design elevation of all support frames, and check the firmness and level of the support frames. The ventilation duct can be hoisted in two ways: immediate and hoisting tools. For the ventilation duct with small cross section and low position, the manual service hoisting method can be used. Only simple steel pipe scaffold can be erected. When the cross section of the ventilation pipe is large and the pipe is long, movable pulley, chain block, large rope and other methods can be used for lifting.

目前的油烟净化技术都各有特点，只要符合有关产品标准，取得指定检测部门的合格检验和认定，就应该使用。任何技术都需要在一定的市场支持下才可能不断完善和提高，这是企业生存之需，也是技术提高的条件。

The current lampblack purification technologies have their own characteristics. As long as they meet the relevant national product standards and obtain the qualification inspection and certification of the national designated testing department, they should be recommended for use. Any technology can only be continuously improved and improved with the support of a certain market, which is the need for the survival of enterprises and the condition for technology improvement.

油烟是食物烹饪、加工过程中挥发的油脂、有机质及其加热分解或裂解产物，它含有对人体器官有强刺激性的物质丙烯醛及致癌物苯并芘。厨房油烟可随空气侵入人体呼吸道，进而引起食欲减退、心烦、精神不振、嗜睡、疲乏无力等症状，医学上称为油烟综合征。目前不锈钢焊接风管的无法兰连接形式有几十种，而且新的形式还在不断出现，但按其结构原理可分为承插、插条、咬合、铁皮法兰和混合式连接五种。无法兰连接主要用于边长较小的风管，有C形插条连接和S形插条连接。

Fume is the volatile oil, organic matter and its heating decomposition or pyrolysis products in the process of food cooking and processing. It contains acrolein, a strong irritant to human organs, and benzopyrene, a carcinogen. Kitchen lampblack can invade human respiratory tract with air, and then cause symptoms such as anorexia, upset, listlessness, lethargy, fatigue and weakness, which is called lampblack syndrome in medicine. At present, there are dozens of flange free connection forms of stainless steel welded air duct, and new forms are emerging constantly, but according to its structural principle, it can be divided into five types: socket, strip, bite, sheet iron flange and hybrid connection. Flangeless connection is mainly used for air duct with small side length, including C-shaped connection and S-shaped connection.
