厨房排烟管道清洗方法：
Cleaning method of kitchen smoke exhaust pipe:
1、厨房每天都在使用，所以排烟管道要经常清洗，比较常见是的采用空降法来进行清洗，主要是由清洗人员拆下管道上截和下截，用清洁剂进行清洗。在清洗的时候要注意，清洗排烟管道的危险性比较大，技术性强，但是清洗效果好。因为竖烟道一般积油较少一年清洗一次即可。
1. The kitchen is used every day, so the smoke exhaust pipe should be cleaned frequently. It is common to use the airborne method for cleaning. The cleaning personnel mainly remove the upper and lower sections of the pipe and clean it with detergent. During cleaning, attention shall be paid to that cleaning the smoke exhaust pipe is dangerous and technical, but the cleaning effect is good. Because the vertical flue generally has less oil accumulation, it can be cleaned once a year.
2、对于比较难清洗的排烟管道，可以采用人工进入法，对于大于45公分的平行烟管道可以人工钻进去清理。但是需要留意加强透风，配备低压(36伏)照明电源。
2. For smoke exhaust pipes that are difficult to clean, the manual entry method can be adopted. For parallel smoke pipes larger than 45 cm, the manual entry method can be used for cleaning. However, attention should be paid to strengthening ventilation and equipping low-voltage (36V) lighting power supply.
3、对于人工无法清洗的地方，可以采用拆卸法，清洗人员要根据现场实际情况，每隔一些时间拆卸一段烟道向两方延伸清理，此法效果好，但是难度较大，用度较高。
3. For places that cannot be cleaned manually, the disassembly method can be adopted. The cleaning personnel shall disassemble a section of flue to extend to both sides for cleaning at regular intervals according to the actual situation of the site. This method has good effect, but it is difficult and expensive.
4、清洗人员可以利用无火花开孔工具将管道进行开孔，这种方法对于无法进入且拆卸较为难题的烟道采用此法。开孔的大小，间隔，数目可以根据现场情况来定，油污清理完后将管道密封复原。
4. The cleaning personnel can use the non sparking opening tool to open the pipe. This method is used for the flue that is inaccessible and difficult to disassemble. The size, spacing and number of openings can be determined according to the site conditions. After the oil stain is cleaned, the pipeline shall be sealed and restored.
