Regular ventilation adopts uniform exhaust, that is, the air duct and vent in the basement are evenly arranged, which can be used for horizontal ventilation, as well as smoke exhaust pipe and vent in case of fire. The basement is considered as a natural ventilation lane, while the other floor is used for normal ventilation to prevent fire disasters, and the mechanical ventilation system does not need to be connected to the supply pipe or a small number of pipes to provide relatively concentrated air, which is more unified and centralized. The exhaust will be good. In addition, each fire zone corresponds to an exhaust, smoke exhaust and air intake system, and shall be equipped with an air intake shaft, an exhaust shaft and an air inlet, with clean ground. When it is far away from the underground main building, it is less affected by the gas; if it is far away from the ground main building, it is less affected by the fire smoke, the exhaust position should be higher than the height of the accessories. Reduce the impact of exhaust on the ground environment.

　　通风91影视在线污污污设备已广泛应用于厨房通风91影视在线污污污、空调通风91影视在线污污污、车库通风、地下室通风91影视在线污污污等行业。接下来，我将给你一个详细的介绍。

　　Ventilation and smoke exhaust equipment has been widely used in kitchen ventilation and smoke exhaust, air conditioning ventilation and smoke exhaust, garage ventilation, basement ventilation and smoke exhaust and other industries. Next, I will give you a detailed introduction.

　　一、厨房通风91影视在线污污污

　　1、 Kitchen ventilation and smoke exhaust

　　有效的厨房通风和91影视在线污污污必须符合以下标准:

　　Effective kitchen ventilation and smoke exhaust must meet the following standards:

　　1. 厨房之间的等温加工间需要通风换气，其中65%由排风罩排出，35%由新风管及通风机排出，每小时40次适宜通风(频率可在产品上设定)。

　　1. The isothermal processing room between the kitchens needs ventilation, of which 65% is discharged by the exhaust hood, 35% is discharged by the fresh air pipe and ventilator, and 40 times per hour is suitable for ventilation (the frequency can be set on the product).

　　2. 引擎盖吸入速度不小于0.5 m/s(购买产品时要求的规格)，排气管速度不大于10 m/s(购买产品时要求的规格)。3.补充空气的数量在厨房和糕点加工的房间应该是大约70%的废气,和室内负压不应大于5 Pa(相关仪器可以测量),所以厨房烹饪产生的烟的气味不会蔓延到饭厅,从而达到隔热绝缘和味觉的影响。

　　2. The suction speed of the engine hood shall not be less than 0.5 m / S (specification required when purchasing the product), and the exhaust pipe speed shall not be more than 10 m / S (specification required when purchasing the product). 3. The amount of supplementary air in the kitchen and pastry processing room should be about 70% of the exhaust gas, and the indoor negative pressure should not be greater than 5 Pa (relevant instruments can be measured), so the smell of smoke generated by cooking in the kitchen will not spread to the dining room, so as to achieve the effect of thermal insulation and taste.

　　随着我国服务业的快速发展，我国正逐步成为一个真正的饮食大国。在享用美食的同时，餐饮厨房的改善和设计管理已经成为一个不可缺少的关键环节，尤其是济南酒店厨房烟罩的处理尤为重要。其中一些问题值得91黄色软件下载注意。

　　With the rapid development of China's service industry, China is gradually becoming a real food country. While enjoying delicious food, the improvement and design management of catering kitchen has become an indispensable key link, especially the treatment of kitchen smoke hood in Jinan hotel. Some of them deserve our attention.

　　，91在线视频观看的水平段在厨房油烟净化器91影视在线污污污工程中不宜过长。特别是烟气净化装置的安装会增加风阻。一般情况下，距离不应超过15米，坡度应大于2%。水平端应设有活动接头，便于清洗91在线视频观看内的油污。新安装的厨房油烟净化器应尽量安装在厨房排风机前面靠近厨房的地方，济南饭店厨房的烟机罩要减少排气管和风机叶轮的油烟附着，延长91在线视频观看的清洗和风机的维护周期。连接排气罩的支管应该配置一个流量控制阀。

　　First of all, the horizontal section of the pipeline should not be too long in the smoke exhaust project of the kitchen fume purifier. In particular, the installation of flue gas purification device will increase wind resistance. In general, the maximum distance shall not exceed 15m, and the slope shall be greater than 2%. The horizontal end shall be provided with a movable joint to facilitate the cleaning of oil stains in the pipeline. The newly installed kitchen fume purifier should be installed as close to the kitchen as possible in front of the kitchen exhaust fan. The hood of the kitchen fume purifier in Jinan hotel should reduce the oil fume attachment of the exhaust pipe and the fan impeller, and extend the cleaning period of the pipe and the maintenance period of the fan. The branch pipe connecting the exhaust hood shall be equipped with a flow control valve.

　　其次，厨房送风系统应采用直流方式，厨房通风工程系统应采用变频风机或相关风机送风、排风。这样，在任何时候产生的大量废气可以更直接和有效地排放到户外。

　　Secondly, the kitchen air supply system shall adopt DC mode, and the kitchen ventilation engineering system shall adopt frequency conversion fan or related fan to supply and exhaust air. In this way, a large amount of waste gas generated at any time can be discharged to the outdoor more directly and effectively.
