长期使用厨房的话，墙砖墙壁上会产生一层黏黏的污渍，即使用去污洗洁精也难以完全。有一种方法可以轻松地祛除墙壁上的油烟。准备洗涤剂、醋、开水， 将三者混合，并且均匀搅拌，取一块干净的抹布浸在混合溶剂中，完全浸湿后取出来拧半干。将抹布上的混合溶剂覆盖在墙壁瓷砖的油渍上，济南厨房排烟闷上一会儿，然后再 擦拭厨房瓷砖。用这样的方式清洗墙面，油渍很容易祛除，值得提醒的是一定要用开水。

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.

对于热压较大的车间其热损失不可低估。大家经常可以看到无逆止装置的排烟风机和轴流风机，在热压作用下风机高速旋转，这一现象说明热压造成的风速相当大，风筒内的风速可达2.0～3.0m/s以上。风机倒转对电动机启动很不利，可能因启动电流过大而损坏。

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：防爆灯、UV灯可以经常用湿抹布擦干净，含有挡水板、运水扇、油网、济南厨房排烟过滤网等前端净化部件的和排烟罩面板一样，都需要先将表面油垢铲干净，然后放在火碱水里泡，待油泥完全泡除后，再用高压水枪(清水)洗净。据经验证明，80%左右的厨房排烟不畅主要原因是油烟净化器的内置过滤网不洁堵塞。所以前端净化器的部件清洁是非常重要的。

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.

利用排烟机把着火房间中产生的烟气通过排烟口排到室外的排烟方式称为负压排烟方式。在火灾发展初期，这种排烟方式能使着火房间内压力下降，造成负压，烟气不会像其它区域扩散。但火灾猛烈发展阶段，由于烟气大量产生，排烟机如来不及把其完全排除，烟气就可能扩散到其它区域中去。另外排烟机要求能承受高温烟气，而且还需要设防火阀，在超温时自动关闭停止排烟。所以，不仅初投资高，而且日常维护管理费用也高。

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：酒店厨房设计师应该进行尖利器防治设计，检索厨房内尖利部位，采取针对性的打磨、钝化处理。此外，要提供稳妥的防滑方案，包括地面处理建议、的防滑科技产品应用、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.

一般水平更远距离不应超过15m并且要有2%以上的坡度，水平末端设活接头，以方便清理油垢。排风速度按规范不得低于10m/s，以防风速过低使油附着于烟道上，接排风罩的支管应设风量调节阀。

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.
