集氣罩的規(guī)劃關(guān)于排煙體系具有重要的影響。集氣罩規(guī)劃不合理就很簡單形成整個排煙體系不暢。引起排煙體系不曉暢的要素有：1）油板間或許運水集氣（煙）罩縫隙過小，這種狀況較多；2）煙罩內(nèi)搜集油煙的開口總的截面積太小而引起全體排煙不曉暢；3）開口分布不合理或是開口沒有跟著與主管道的距離增大而增大，然后引起部分排煙不曉暢；4）集氣（煙）罩上面的集煙管道截面積太小，導(dǎo)致出煙不曉暢。
The layout of the hood has important influence on the exhaust system. The layout of the hood is unreasonable, and the whole exhaust system is not smooth. The main factors causing the smoke exhaust system to be unobstructed are: 1) the gap between the oil panels may be too small, which is more common; 2) the total cross-sectional area of the oil fume collection opening in the hood is too small to cause the smoke exhaust to be unobstructed; 3) the distribution of the opening is unreasonable or the opening does not increase with the distance from the main pipe. Then cause part of the smoke exhaust is not clear; 4) collector (smoke) cover above the cross-sectional area of the smoke collection pipe is too small, resulting in smoke not clear.
濟(jì)南廚房排煙罩主要由集煙罩、排煙管道、油煙凈化器、排煙風(fēng)機(jī)（含*）和廚房全體補(bǔ)風(fēng)設(shè)備構(gòu)成，辦法如下:
Jinan kitchen smoke hood is mainly composed of smoke hood, smoke exhaust pipe, lampblack purifier, smoke exhaust fan (including *) and all kitchen air supply equipment, the methods are as follows:
1、固定煙機(jī)掛板：在裝置方位鉆好孔用十字螺絲將包裝箱順便的煙機(jī)掛板固定在墻上；
1. Fixing the hanging board of the cigarette machine: drilling holes in the orientation of the device and fixing the hanging board of the cigarette machine incidentally to the wall with the cross screw;
2、將煙機(jī)掛在掛板上：將吸油煙機(jī)掛到掛板上，確保吸油煙機(jī)無晃動和脫鉤現(xiàn)象并盡量確保水平；
2. Hang the smoke machine on the hanging board: hang the lampblack machine on the hanging board to ensure that the lampblack machine does not shake and decouple and to ensure the level as far as possible;
3、裝置排煙管：將排煙管的一端與吸油煙機(jī)上的出風(fēng)口銜接，另一端則與共用煙道或外墻上的墻孔銜接。若排煙到共用煙道，勿將排煙管刺進(jìn)過深導(dǎo)致排煙阻力增大，若排煙到墻外，則主張在排煙管外裝上百葉窗，一起務(wù)必使排煙管口伸出30mm，防止回灌；
3. Device exhaust pipe: connect one end of the exhaust pipe with the air outlet on the lampblack suction machine, and the other end with the common flue or wall hole on the outer wall. If the smoke is exhausted to the common flue, do not puncture the smoke pipe too deep to increase the smoke exhaust resistance. If the smoke is exhausted to the wall, it is advocated to install shutters outside the smoke exhaust pipe, together with the smoke exhaust pipe must be extended 30 mm to prevent re-filling.
4、裝置油杯：將油杯擰上或是推入到位固定好。
4. Install the oil cup: screw the oil cup or push it in place.
因為廚房所在建筑物的格局以及廚房在建筑物中方位不同，有條件的廚房應(yīng)由建筑物的會集空調(diào)體系進(jìn)行有序送風(fēng)。但目前所遇到的大部分狀況是建筑物沒有設(shè)置廚房的送風(fēng)體系。濟(jì)南廚房排煙罩許多帶餐廳、廚房等的建筑物，僅規(guī)劃了會集采暖體系而無會集空調(diào)體系。當(dāng)廚房處于作業(yè)狀況時，排風(fēng)體系投入運行，廚房內(nèi)處于負(fù)壓狀況，新風(fēng)來歷包含室外新風(fēng)浸透和餐廳的空氣很多補(bǔ)入廚房。
Because the layout of the building where the kitchen is located and the orientation of the kitchen in the building is different, the conditional kitchen should be orderly air supply by the building's air conditioning system. But most of the current situation is that the building has no kitchen air supply system. Jinan kitchen smoke hood with many restaurants, kitchens and other buildings, only the planning of the assembly heating system without the assembly air conditioning system. When the kitchen is in operation, the exhaust system is put into operation, the kitchen is in a negative pressure condition, fresh air has always included outdoor fresh air soaking and dining room air into the kitchen.
用兩臺機(jī)組分別為餐廳、廚房服務(wù)，其間廚房為全新風(fēng)直流體系，直接彌補(bǔ)廚房爐灶的排風(fēng)，而餐廳為一次回風(fēng)全新空氣體系，這個計劃能確保餐廳和廚房的空調(diào)作用，并且廚房和餐廳體系互不攪擾，缺點是初出資較大。
The kitchen serves the dining room and the kitchen respectively. The kitchen is a fresh air direct current system, which directly compensates for the exhaust of the kitchen stove. The dining room is a fresh air system with one return. This plan can ensure the air conditioning function of the dining room and the kitchen, and the kitchen and the dining room system are not disturbed each other. The disadvantage is that the initial investment is large.
Ji'nan smoke hood, please continue to pay attention to the content: http://www.shanghaizhuangxiu8.com/, we will serve you wholeheartedly.
