In the design of hotel kitchen, Jinan smoke hood has many links that need special treatment.

長期使用廚房的話，墻磚墻壁上會產生一層黏黏的污漬，即使用去污洗潔精也難以完全。有一種方法可以輕松地祛除墻壁上的油煙。準備洗滌劑、醋、開水， 將三者混合，并且均勻攪拌，取一塊干凈的抹布浸在混合溶劑中，完全浸濕后取出來擰半干。將抹布上的混合溶劑覆蓋在墻壁瓷磚的油漬上，濟南廚房排煙悶上一會兒，然后再 擦拭廚房瓷磚。用這樣的方式清洗墻面，油漬很容易祛除，值得提醒的是一定要用開水。

If you use the kitchen for a long time, there will be a layer of sticky stains on the walls of the wall tiles. It is also difficult to completely remove them with detergent. There is a way to get rid of the lampblack on the wall easily. Prepare detergent, vinegar and boiled water, mix them, mix them evenly, take a clean rag and soak it in the mixed solvent, soak it completely, take it out and screw it to half dry. Cover the mixed solvent on the dishcloth on the oil stain of the wall tile, smoke exhaust in Jinan kitchen for a while, and then wipe the kitchen tile. With this way to clean the wall, oil stains are easy to remove, it is worth reminding that we must use boiled water.

對于熱壓較大的車間其熱損失不可低估。大家經?？梢钥吹綗o逆止裝置的排煙風機和軸流風機，在熱壓作用下風機高速旋轉，這一現象說明熱壓造成的風速相當大，風筒內的風速可達2.0～3.0m/s以上。風機倒轉對電動機啟動很不利，可能因啟動電流過大而損壞。

For the workshop with large hot pressing, the heat loss should not be underestimated. You can often see the smoke exhaust fan and axial flow fan without check device, under the action of hot pressure, the fan rotates at high speed, which shows that the wind speed caused by hot pressure is quite large, and the wind speed in the air duct can reach more than 2.0-3.0m/s. Fan reverse is very harmful to motor starting, and may be damaged due to excessive starting current.

清洗方法：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、濟南廚房排煙過濾網等前端凈化部件的和排煙罩面板一樣，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。

Cleaning method: the explosion-proof lamp and UV lamp can be often wiped with wet cloth. The front-end purification parts including water baffle, water fan, oil screen, Jinan kitchen smoke filter screen, etc. are the same as the smoke hood panel. They need to shovel the surface oil dirt first, then put it in the caustic soda water for soaking, and then wash it with high-pressure water gun (clean water) after the oil mud is completely soaked. According to experience, 80% of the kitchen exhaust is not smooth, mainly because the built-in filter screen of the fume purifier is not clean and blocked. Therefore, it is very important to clean the components of the front-end purifier.

利用排煙機把著火房間中產生的煙氣通過排煙口排到室外的排煙方式稱為負壓排煙方式。在火災發展初期，這種排煙方式能使著火房間內壓力下降，造成負壓，煙氣不會像其它區域擴散。但火災猛烈發展階段，由于煙氣大量產生，排煙機如來不及把其完全排除，煙氣就可能擴散到其它區域中去。另外排煙機要求能承受高溫煙氣，而且還需要設防火閥，在超溫時自動關閉停止排煙。所以，不僅初投資高，而且日常維護管理費用也高。

The way of exhausting smoke from the fire room to the outside through the smoke vent is called negative pressure exhausting. In the early stage of fire development, this kind of smoke exhaust method can reduce the pressure in the fire room, cause negative pressure, and the smoke will not spread like other areas. However, in the fierce development stage of fire, due to the large amount of smoke generated, if the smoke extractor fails to completely eliminate it, the smoke may spread to other areas. In addition, the smoke extractor shall be able to withstand high temperature smoke, and fire damper shall be set to automatically close and stop smoke exhaust in case of over temperature. Therefore, not only the initial investment is high, but also the daily maintenance and management costs are high.

保障：酒店廚房設計師應該進行尖利器防治設計，檢索廚房內尖利部位，采取針對性的打磨、鈍化處理。此外，要提供穩妥的防滑方案，包括地面處理建議、的防滑科技產品應用、防滑部位改良等措施。

Safety guarantee: the hotel kitchen designer should carry out the sharp tool prevention and control design, comprehensively search the sharp parts in the kitchen, and take targeted polishing and passivation treatment. In addition, it is necessary to provide a comprehensive and stable anti-skid scheme, including ground treatment suggestions, advanced anti-skid technology product application, key anti-skid parts improvement and other measures.

一般水平更遠距離不應超過15m并且要有2%以上的坡度，水平末端設活接頭，以方便清理油垢。排風速度按規范不得低于10m/s，以防風速過低使油附著于煙道上，接排風罩的支管應設風量調節閥。

Generally, the longest horizontal distance shall not exceed 15m and the gradient shall be more than 2%. Movable joints shall be set at the horizontal end to facilitate the cleaning of oil dirt. The exhaust speed shall not be lower than 10m / s according to the specification, so as to prevent the oil from adhering to the flue due to the low wind speed. The branch pipe connected with the exhaust hood shall be equipped with an air volume regulating valve.
