Smoke exhaust system and purifier are two very important equipment, which can help kitchen and hotel ventilation and smoke purification. In this paper, we describe some installation precautions and related knowledge about smoke exhaust pipe and purifier.

如果排煙系統(tǒng)設(shè)計(jì)不合理，整個(gè)廚房的排煙不順暢，就不會(huì)安裝油煙凈化器，即使安裝了油煙凈化器，也不會(huì)正常工作；在實(shí)際的油煙排煙系統(tǒng)和凈化器設(shè)計(jì)中，缺乏可靠、實(shí)用的計(jì)算方法。掌握排油煙系統(tǒng)各部分的特點(diǎn)及其對(duì)整個(gè)廚房排油煙的影響，是選擇和安裝油煙凈化器的前提，對(duì)保證油煙凈化器的正常運(yùn)行具有重要意義。

If the design of smoke exhaust system is unreasonable and the smoke exhaust of the whole kitchen is not smooth, the fume purifier will not be installed, even if the fume purifier is installed, it will not work normally; in the actual design of fume exhaust system and purifier, there is a lack of reliable and practical calculation method. Mastering the characteristics of each part of the fume exhaust system and its influence on the whole kitchen fume exhaust is the premise of selecting and installing the fume purifier, which is of great significance to ensure the normal operation of the fume purifier.

對(duì)于餐飲行業(yè)的廚房來(lái)說(shuō)，濟(jì)南排煙管道是否通暢直接關(guān)系到廚房的正常運(yùn)行，而油煙凈化只是廚房排煙系統(tǒng)中凈化空氣功能。排煙系統(tǒng)與凈化器的合理匹配是保證油煙凈化器凈化效率的關(guān)鍵。

For the kitchen of catering industry, whether the exhaust pipe of Jinan is unobstructed is directly related to the normal operation of the kitchen, and the oil fume purification is only the air purification function in the kitchen exhaust system. The reasonable matching of exhaust system and purifier is the key to ensure the purification efficiency of oil fume purifier.

現(xiàn)在烹飪油煙以氣溶膠的形式漂浮在空氣中，是城市大氣中可吸入顆粒物污染的重要來(lái)源之一，將對(duì)大氣環(huán)境和人體健康造成非常大的危害，為烹飪油煙治理提供了法律依據(jù)，有用控制了城市烹飪油煙污染。但在實(shí)際運(yùn)行中，仍有相當(dāng)數(shù)量的油煙凈化設(shè)備由于設(shè)計(jì)不合理或管理不善，凈化效率較低，未能達(dá)到預(yù)期效果。

Now cooking fume floats in the air in the form of aerosol, which is one of the important sources of inhalable particulate matter pollution in the urban atmosphere. It will cause great harm to the atmospheric environment and human health. It provides a legal basis for the treatment of cooking fume and effectively controls the pollution of cooking fume in the city. But in the actual operation, there are still a considerable number of fume purification equipment, due to unreasonable design or poor management, the purification efficiency is low, and the expected effect can not be achieved.

1.確定油煙機(jī)距離加工和烹飪臺(tái)的高度，一般為170-180厘米。

1. Determine the distance between the range hood and the processing and cooking table, generally 170-180 cm.

2.根據(jù)待加工烹飪臺(tái)的大小，油煙罩下口的長(zhǎng)度和寬度可加20-40cm確定。

2. According to the size of the cooking table to be processed, the length and width of the lower opening of the hood can be determined by adding 20-40cm.

3.確定從油煙機(jī)下口到油煙機(jī)排煙口的通風(fēng)口的傾斜度和高度。

3. Determine the inclination and height of the vent from the lower outlet of the range hood to the exhaust outlet of the range hood.

濟(jì)南排煙罩主要用于工業(yè)和建筑工程。主要應(yīng)用領(lǐng)域有：電子行業(yè)的潔凈車(chē)間凈化系統(tǒng)，酒店、、醫(yī)院、工廠、辦公樓的空調(diào)系統(tǒng)，除塵用的排煙管，工業(yè)污染治理用的排煙吸油管，工業(yè)環(huán)境或工作舒服程度的送風(fēng)管等。不同的行業(yè)需要安裝不同的廚房排煙管道。

Jinan smoke hood is mainly used in industrial and construction projects. The main application fields are: clean workshop purification system of electronic industry, air conditioning system of hotels, shopping malls, hospitals, factories and office buildings, smoke exhaust pipe for dust removal, smoke exhaust and oil suction pipe for industrial pollution control, air supply pipe for industrial environment or work comfort, etc. Different industries need to install different kitchen exhaust pipes.
