When selecting oil fume purification and smoke exhaust facilities in the kitchen of a hotel, priority should be given to the size of the smoke exhaust equipment. After determining the size of the smoke exhaust equipment, the size of the oil fume purifier equipment should be selected. Generally, the air volume of the oil fume purifier should be greater than 20% of the fan air volume.

具体到排烟风机的选型，需要根据烟罩的大小，炉灶数量，总管道长度，弯头数量；排烟管路中其他设备阻力等参数选择。

The specific selection of smoke exhaust fans needs to be based on the size of the hood, the number of stoves, the total length of the pipeline, and the number of elbows; Select parameters such as resistance of other equipment in the smoke exhaust pipeline.

酒店商用厨房抽排油烟通风系统设计原则和划分要与客户的投资方向、投资预算、能源效率、能源消耗、运行费用、生产流程等结合起来，

The design principles and division of the fume exhaust and ventilation system for hotel commercial kitchens should be combined with the client's investment direction, investment budget, energy efficiency, energy consumption, operating costs, production processes, etc,

排风量的确定和风速设计原则由两部分组成:局部排风量和排风量。局部排风量应根据选用的灶具等设备种类、数量以及抽排烟的型式等加以确定，即根据炉灶等设备的平面布置图,烟草种类,抽油烟离心风机的除油烟方式及设备产生风机性能的强度等因素进行确定。

The determination of exhaust air volume and the principle of wind speed design consist of two parts: local exhaust air volume and comprehensive exhaust air volume. The local exhaust air volume should be determined based on the type and quantity of selected stoves and other equipment, as well as the type of smoke extraction and exhaust, that is, based on the layout plan of the stove and other equipment, the type of tobacco, the method of removing oil smoke from the centrifugal fan for oil smoke extraction, and the strength of the fan performance generated by the equipment.

酒店厨房通风排烟系统在安装时，也需要注意：要减少弯头，尽量做到更短路线排放，要装防火阀避免火灾隐患；管道过长时要做好支架的固定，避免出现脱落；风机和净化器尽量保持在一个水平位置上；连接件必须密封。

When installing the ventilation and smoke exhaust system in the hotel kitchen, it is also necessary to pay attention to reducing bends, minimizing emissions along the shortest possible route, and installing fire dampers to avoid potential fire hazards; When the pipeline is too long, the support should be fixed properly to avoid falling off; Try to keep the fan and purifier in a horizontal position as much as possible; The connecting parts must be sealed.

另外，厨房排烟风机净化器安装在室内的时候，一定要预留好后期检修的空间。后期要定期做好管道的清理，避免发生隐患。

In addition, when installing the kitchen exhaust fan purifier indoors, it is necessary to reserve space for later maintenance. Regular cleaning of pipelines should be carried out in the later stage to avoid potential safety hazards.
