酒店排煙罩使用說明：一般用于酒店的風機排煙罩有會帶走酒店大量空氣，油煙罩補風風機—抽油煙時，需向酒店補充空氣，該機提供約占排油煙風量的80%。工作區新風預處理風機—為酒店工作區（人員工作位置）提供經過預處理的新風。
Instructions for the use of smoke exhaust hood in hotels: The smoke exhaust hood of fans generally used in hotels will take away a lot of air from the hotel. When the air make-up fan of lampblack hood is used to extract lampblack, it needs to supplement air to the hotel, which provides about 80% of the air volume of lampblack exhaust. Fresh air pre-treatment fan in the working area - provides the hotel working area (staff working position) with pretreated fresh air.
該機提供約占排油煙風量的20%排油煙風機—排去煮食區油煙罩的油氣。各風管的接駁處需采取防漏風措施。為保證設備的傳染效力與設備進出風口毗連的變徑風管要盡量平順。為保證設備的傳染效力，必須裝配長度比管徑大4倍以上的直管，并采用平順的管道來連接，所以設備輕風機的風管連接時必須采用軟連接。設備運行時受到振動將不能正常任務。
This machine provides a lampblack exhaust fan that accounts for about 20% of the lampblack exhaust air volume - to exhaust the oil and gas from the lampblack hood in the cooking area. Air leakage prevention measures shall be taken at the connection of each air duct. In order to ensure the infectious effect of the equipment, the variable diameter air duct adjacent to the equipment inlet and outlet shall be as smooth as possible. In order to ensure the infectious effect of the equipment, straight pipes with a length more than 4 times the pipe diameter must be assembled and connected with smooth pipes. Therefore, flexible connection must be used when connecting the air pipes of the equipment's light fans. The equipment will not work normally if it is subject to vibration during operation.
餐飲行業的廚房油煙主要以氣溶膠的形態漂浮在空氣中，是城市大氣中可吸入顆粒物污染的重要來源之一，濟南排煙管道對大氣環境及人體健康會造成極大的危害。
Kitchen lampblack in catering industry mainly floats in the air in the form of aerosol, which is one of the important sources of inhalable particulate matter pollution in urban atmosphere. Jinan smoke exhaust pipe will cause great harm to the atmospheric environment and human health.
濟南廚房排煙為油煙治理提供了法律依據，使城市中餐飲業油煙污染得到了有效的控制。但在實際行動中，仍有相當一部分的油煙凈化器設備由于設計不合理或管理不善，凈化效率低，沒有達到預想的效果。
Jinan kitchen smoke provides a legal basis for lampblack control, which effectively controls the lampblack pollution of urban Chinese food and beverage industry. However, in practice, there are still a considerable number of lampblack purifiers that have not achieved the expected effect due to unreasonable design or poor management and low purification efficiency.
防爆燈、UV燈可以經常用濕抹布擦干凈，含有擋水板、運水扇、油網、過濾網等前端凈化部件的和排煙罩面板一樣，濟南排煙管道都需要先將表面油垢鏟干凈，然后放在火堿水里泡，待油泥完全泡除后，再用高壓水槍(清水)洗凈。據經驗證明，80%左右的廚房排煙不暢主要原因是油煙凈化器的內置過濾網不潔堵塞。所以前端凈化器的部件清潔是非常重要的。
Explosion proof lamps and UV lamps can often be wiped clean with a wet rag. Those containing water baffle, water fan, oil screen, filter screen and other front-end purification components are the same as those of the smoke exhaust hood panel. Jinan smoke exhaust pipes need to shovel the oil dirt on the surface first, and then soak in caustic water. After the oil sludge is completely soaked, they can be cleaned with a high-pressure water gun (clean water). According to experience, about 80% of kitchens have poor smoke exhaust, which is mainly caused by the dirty and blocked filter screen inside the oil smoke purifier. Therefore, it is very important to clean the components of the front-end purifier.
每家的廚房里都有煙道，同時煙道也有主副之分，主煙道貫穿整個樓體，而副煙道是相對獨立的。一般家里的油煙會先到副煙道里，然后再通過隔板上的孔進入主煙道，這樣可保證每戶的油煙是隔離開來的。而如果將副煙道直接連接主煙道，就會由于壓力過低而導致倒煙或串煙現象。
Each kitchen has a flue, and the flue can be divided into main flue and auxiliary flue. The main flue runs through the whole building, while the auxiliary flue is relatively independent. Generally, the lampblack in the home will go to the auxiliary flue first, and then enter the main flue through the hole on the partition board, so as to ensure that the lampblack in each household is isolated. If the auxiliary flue is directly connected to the main flue, the pressure will be too low, which will lead to the phenomenon of back smoke or smoke.
Jinan smoke exhaust hood focuses on the production and processing of kitchen smoke exhaust hood and other products. For more highlights, please click here: http://m.pvcbox.cn , we will have more wonderful content for you to check
