对于饮食业的厨房来说，排烟是否通畅直接关系到厨房能否正常工作，油烟净化则只是厨房排烟系统中的一个净化空气的强制性功能。排烟系统和净化器的合理匹配是保证油烟净化器净化效率的关键，同时也是油烟净化器设计人员容易忽略的问题。如果排烟系统设计不合理而造成整个厨房排烟不畅，则将无法安装油烟净化器，即使安装了油烟净化器也无法正常工作。由于在 GB18483-2001中没有给出关于油烟排风收集系统与净化器匹配保定平面设计培训 收费岛模具 挡土墙模具 防撞墙模具 防撞墙模具 防撞护栏模具 大棚遮阳网 遮阴网的计算依据，因而在实际进行油烟排风系统和净化器的设计时缺乏可靠实用的计算方法。掌握排烟系统的各部分特性及其对厨房整体排烟的影响，是进行油烟净化器选型和安装的前提，对于保证油烟净化器的正常工作具有非常重要的意义。
For the kitchen of catering industry, whether the smoke exhaust is unobstructed is directly related to whether the kitchen can work normally. Oil fume purification is only a mandatory function of purifying air in the kitchen smoke exhaust system. The reasonable matching of smoke exhaust system and purifier is the key to ensure the purification efficiency of oil fume purifier, and it is also a problem easy to be ignored by oil fume purifier designers. If the smoke exhaust system design is unreasonable and the smoke exhaust of the whole kitchen is not smooth, the oil fume purifier will not be installed, and even if the oil fume purifier is installed, it will not work normally. Because GB18483-2001 does not give the calculation basis for the matching of oil fume exhaust air collection system and purifier, there is a lack of reliable and practical calculation method in the actual design of oil fume exhaust air system and purifier. Mastering the characteristics of each part of the smoke exhaust system and its impact on the overall smoke exhaust of the kitchen is the premise for the selection and installation of the oil fume purifier, which is of great significance to ensure the normal operation of the oil fume purifier.
