在小室內(nèi)空間里打造耐用美麗的家庭廚房，讓室內(nèi)空間看上去不擁堵，讓廚柜夠個性化，全體化感覺夠時尚，在方寸之地更好地依托各式各樣廚具設(shè)備，以抵達(dá)別有洞天、物我融洽的實際作用，需要動動腦筋。為了便于風(fēng)道就位，一般多采用將風(fēng)道吊在腳手架上，然后再將其抬放在風(fēng)道支架上的方法。腳手架應(yīng)沿其風(fēng)道長度方向搭設(shè)，高度和位置應(yīng)適合施工操作，吊裝順序應(yīng)先干管后支、立管，吊起時，吊點(diǎn)應(yīng)牢固，兩吊點(diǎn)應(yīng)均勻受力。垂直風(fēng)管可采用人工和大繩輔助就位。調(diào)整風(fēng)管保證垂直度要求。

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.

通風(fēng)管道的制做安裝對氣體流通效果影響非常大，因此當(dāng)通風(fēng)管道安裝后，一定要開展品質(zhì)驗收。管路吊裝前要查驗所有支撐架的平整度和設(shè)計標(biāo)高，查驗支撐架的堅固水平，通風(fēng)風(fēng)管吊裝可選用立即和吊裝工具二種方式。對通風(fēng)風(fēng)管橫斷面較小，又部位較低的，可選用人工服務(wù)吊裝法，只需架設(shè)簡單鋼管腳手架只能。當(dāng)通風(fēng)管道橫斷面很大且管道較長時，可選用動滑輪、倒鏈、大繩等方式起吊。

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.

目前的油煙凈化技術(shù)都各有特點(diǎn)，只要符合有關(guān)產(chǎn)品標(biāo)準(zhǔn)，取得指定檢測部門的合格檢驗和認(rèn)定，就應(yīng)該使用。任何技術(shù)都需要在一定的市場支持下才可能不斷完善和提高，這是企業(yè)生存之需，也是技術(shù)提高的條件。

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.

油煙是食物烹飪、加工過程中揮發(fā)的油脂、有機(jī)質(zhì)及其加熱分解或裂解產(chǎn)物，它含有對人體器官有強(qiáng)刺激性的物質(zhì)丙烯醛及致癌物苯并芘。廚房油煙可隨空氣侵入人體呼吸道，進(jìn)而引起食欲減退、心煩、精神不振、嗜睡、疲乏無力等癥狀，醫(yī)學(xué)上稱為油煙綜合征。目前不銹鋼焊接風(fēng)管的無法蘭連接形式有幾十種，而且新的形式還在不斷出現(xiàn)，但按其結(jié)構(gòu)原理可分為承插、插條、咬合、鐵皮法蘭和混合式連接五種。無法蘭連接主要用于邊長較小的風(fēng)管，有C形插條連接和S形插條連接。

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.
