廚房排煙管道清洗方法：
Cleaning method of kitchen smoke exhaust pipe:
1、廚房每天都在使用，所以排煙管道要經常清洗，比較常見是的采用空降法來進行清洗，主要是由清洗人員拆下管道上截和下截，用清潔劑進行清洗。在清洗的時候要注意，清洗排煙管道的危險性比較大，技術性強，但是清洗效果好。因為豎煙道一般積油較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、對于比較難清洗的排煙管道，可以采用人工進入法，對于大于45公分的平行煙管道可以人工鉆進去清理。但是需要留意加強透風，配備低壓(36伏)照明電源。
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、對于人工無法清洗的地方，可以采用拆卸法，清洗人員要根據現場實際情況，每隔一些時間拆卸一段煙道向兩方延伸清理，此法效果好，但是難度較大，用度較高。
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、清洗人員可以利用無火花開孔工具將管道進行開孔，這種方法對于無法進入且拆卸較為難題的煙道采用此法。開孔的大小，間隔，數目可以根據現場情況來定，油污清理完后將管道密封復原。
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.
