　　在濟(jì)南，燒烤是街頭巷尾的煙火擔(dān)當(dāng)，無(wú)論是熱鬧的燒烤店，還是熙攘的美食廣場(chǎng)燒烤區(qū)，食客們大快朵頤之時(shí)，大量油煙也隨之產(chǎn)生。此時(shí)，通風(fēng)管道就如同一位默默守護(hù)的衛(wèi)士，肩負(fù)著凈化空氣、維持舒適環(huán)境的重任。不過(guò)，燒烤區(qū)獨(dú)特的排煙需求，讓通風(fēng)管道的設(shè)計(jì)與安裝有著特殊考量。

　　In Jinan, barbecue is the source of fireworks on the streets and alleys. Whether it's lively barbecue restaurants or bustling food court barbecue areas, as diners feast on their food, a large amount of oil fumes are also produced. At this moment, the ventilation duct is like a silent guardian, shouldering the responsibility of purifying the air and maintaining a comfortable environment. However, the unique smoke exhaust requirements of the barbecue area require special considerations for the design and installation of ventilation ducts.

　　高效捕煙，精準(zhǔn)定位源頭

　　Efficient smoke capture and precise source positioning

　　燒烤區(qū)的油煙產(chǎn)生集中且量大，首要任務(wù)是在源頭精準(zhǔn)捕捉。排煙罩的設(shè)計(jì)至關(guān)重要，需根據(jù)燒烤爐具的布局、數(shù)量與規(guī)格量身定制。常見(jiàn)的有下吸式和上吸式排煙罩。下吸式排煙罩安裝在燒烤爐下方，能第一時(shí)間捕獲從烤架縫隙中逸出的油煙，對(duì)于桌面式燒烤爐十分適用，如一些日式烤肉店，食客圍坐，下吸式排煙罩可確保每個(gè)座位周邊的油煙都

　　The production of oil fumes in the barbecue area is concentrated and large, and the primary task is to accurately capture them at the source. The design of the exhaust hood is crucial and needs to be customized according to the layout, quantity, and specifications of the barbecue stove. Common types include downward suction and upward suction smoke exhaust hoods. The downward suction smoke exhaust hood is installed under the barbecue grill, which can capture the oil smoke escaping from the gaps of the grill in a timely manner. It is very suitable for desktop barbecue grills, such as some Japanese style barbecue restaurants where diners sit around. The downward suction smoke exhaust hood can ensure that the oil smoke around each seat is collected

　　被及時(shí)吸，避免油煙在食客間彌漫。上吸式排煙罩則安裝在烤爐上方，適用于大型燒烤店的集中式烤爐，其面積大、吸力強(qiáng)，可將烤爐上方一定范圍內(nèi)的油煙盡收囊中。例如，濟(jì)南一些傳統(tǒng)燒烤老店，烤串師傅在一排長(zhǎng)長(zhǎng)的烤爐前忙碌，上方大面積的上吸式排煙罩，能高效收集烤制過(guò)程中產(chǎn)生的滾滾油煙，確保店內(nèi)空氣保持相對(duì)清新。

　　Be promptly sucked in to avoid the spread of oil fumes among diners. The upward suction exhaust hood is installed above the oven and is suitable for centralized ovens in large barbecue restaurants. It has a large area and strong suction power, and can collect the oil fumes within a certain range above the oven. For example, in some traditional barbecue restaurants in Jinan, skewers chefs are busy in front of a long row of ovens. The large upward suction smoke hood above can efficiently collect the rolling oil fumes generated during the baking process, ensuring that the air inside the restaurant remains relatively fresh.

　　強(qiáng)大動(dòng)力，保障油煙速排

　　Powerful power ensures fast exhaust of oil fumes

　　燒烤產(chǎn)生的油煙量大且濃度高，需要通風(fēng)管道具備強(qiáng)大的排風(fēng)動(dòng)力。風(fēng)機(jī)作為通風(fēng)系統(tǒng)的 “心臟”，其選型極為關(guān)鍵。要依據(jù)燒烤區(qū)的空間大小、爐具數(shù)量以及預(yù)估的油煙產(chǎn)生量，計(jì)算出合適的排風(fēng)量，從而選擇匹配功率的風(fēng)機(jī)。在小型燒烤店，一臺(tái)功率適中的軸流風(fēng)機(jī)或許就能滿足需求，它結(jié)構(gòu)簡(jiǎn)單、安裝方便，能以較高的風(fēng)速將油煙快速排出室外。而大型美食廣場(chǎng)的燒烤區(qū)，由于涉及多個(gè)攤位，油煙產(chǎn)生總量大，就需選用離心風(fēng)機(jī)，其風(fēng)壓高、風(fēng)量穩(wěn)定，即便通風(fēng)管道較長(zhǎng)、彎頭較多，也能確保油煙順利排出，避免在管道內(nèi)積聚。比如某大型商場(chǎng)的美食廣場(chǎng)，多個(gè)燒烤攤位集中，離心風(fēng)機(jī)通過(guò)合理布局的通風(fēng)管道，將各個(gè)攤位的油煙統(tǒng)一收集并高效排出，保障整個(gè)美食廣場(chǎng)的空氣質(zhì)量。

　　Barbecue produces a large amount and high concentration of oil fumes, requiring ventilation ducts to have strong exhaust power. As the "heart" of a ventilation system, the selection of fans is extremely crucial. The appropriate exhaust volume should be calculated based on the size of the barbecue area, the number of stoves, and the estimated amount of oil fume generated, in order to select a fan with matching power. In a small barbecue restaurant, a moderately powered axial fan may be sufficient to meet the demand. It has a simple structure, easy installation, and can quickly exhaust oil fumes outdoors with high wind speed. In the barbecue area of a large food court, due to the involvement of multiple stalls, the total amount of oil fume generated is large. Therefore, centrifugal fans need to be used, which have high air pressure and stable air volume. Even if the ventilation ducts are long and have many bends, they can ensure the smooth discharge of oil fume and avoid accumulation in the ducts. For example, in the food court of a large shopping mall, multiple barbecue stalls are concentrated, and centrifugal fans collect and efficiently exhaust the fumes from each stall through a properly arranged ventilation duct, ensuring the air quality of the entire food court.

　　材質(zhì)精選，應(yīng)對(duì)高溫油脂

　　Selected materials to cope with high temperature grease

　　燒烤過(guò)程中，油煙溫度較高，且富含油脂，這對(duì)通風(fēng)管道的材質(zhì)提出了嚴(yán)格要求。首選不銹鋼材質(zhì)，其具有出色的耐高溫性能，能承受燒烤油煙的高溫沖擊而不變形、不損壞。同時(shí)，不銹鋼表面光滑，油脂不易附著，方便后期清洗維護(hù)。在一些對(duì)美觀度有要求的燒烤場(chǎng)所，還可選用經(jīng)過(guò)特殊處理的彩色不銹鋼管道，既滿足排煙功能，又能與店內(nèi)裝修風(fēng)格相融合。此外，對(duì)于靠近燒烤爐具的部分管道，可采用雙層結(jié)構(gòu)，內(nèi)層耐高溫耐腐蝕，外層起到隔熱作用，防止?fàn)C傷周邊人員，進(jìn)一步提升安全性。

　　During the barbecue process, the temperature of the cooking fumes is high and rich in oil, which imposes strict requirements on the material of the ventilation ducts. The preferred material is stainless steel, which has excellent high temperature resistance and can withstand the high temperature impact of barbecue fumes without deformation or damage. At the same time, the surface of stainless steel is smooth and grease is not easy to adhere, making it convenient for later cleaning and maintenance. In some barbecue venues that require aesthetic appeal, specially treated colored stainless steel pipes can also be used to meet the smoke exhaust function and blend with the interior decoration style. In addition, for the pipes near the barbecue stove, a double-layer structure can be used, with the inner layer being heat-resistant and corrosion-resistant, and the outer layer serving as insulation to prevent burns to surrounding personnel and further enhance safety.

　　定期維護(hù)，保持系統(tǒng) “健康”

　　Regular maintenance to keep the system 'healthy'

　　燒烤區(qū)通風(fēng)管道的維護(hù)不可或缺。由于油煙中油脂含量高，長(zhǎng)時(shí)間使用后管道內(nèi)壁會(huì)附著厚厚的油垢，不僅影響排煙效率，還存在火災(zāi)隱患。因此，需制定定期清洗計(jì)劃?？刹捎脤I(yè)的管道清洗設(shè)備，如高壓水槍配合專用的除油清洗劑，將管道內(nèi)的油垢徹底清除。同時(shí)，要定期檢查風(fēng)機(jī)的運(yùn)行狀況，查看葉輪是否有磨損、電機(jī)是否運(yùn)轉(zhuǎn)正常，及時(shí)更換損壞部件，確保風(fēng)機(jī)始終處于良好的工作狀態(tài)。此外，對(duì)通風(fēng)管道的各個(gè)連接部位進(jìn)行檢查，防止因油煙侵蝕導(dǎo)致接口松動(dòng)、漏風(fēng)，影響排煙效果。

　　The maintenance of ventilation ducts in the barbecue area is indispensable. Due to the high oil content in cooking fumes, thick oil stains will adhere to the inner wall of the pipeline after prolonged use, which not only affects smoke exhaust efficiency but also poses a fire hazard. Therefore, a regular cleaning plan needs to be developed. Professional pipeline cleaning equipment can be used, such as high-pressure water guns combined with specialized oil removal cleaning agents, to thoroughly remove oil stains from the pipeline. At the same time, it is necessary to regularly check the operation status of the fan, check whether the impeller is worn, whether the motor is running normally, replace damaged parts in a timely manner, and ensure that the fan is always in good working condition. In addition, check the various connection parts of the ventilation ducts to prevent loose interfaces and air leaks caused by oil fume erosion, which may affect the smoke exhaust effect.
