The installation and cleaning personnel first remove the upper and lower sections of the pipeline, which is known as the airborne method. This method is mainly used to clean vertical flues above 50 centimeters square. Fix a high-altitude safety rope above the flue, fasten a safety belt, and install cleaning personnel to clean the oil stains inside the vertical flue from top to bottom. This method is highly dangerous, technical, and highly effective in cleaning. Because the vertical flue generally has less oil accumulation, it can be cleaned once a year.

此法勞動強度較大，即人工進入法，對于大于40公分見方的平行煙道可以人工鉆進去進行清理。需要留意加強透風，配備低壓(36伏)照明電源。

This method has a high labor intensity, which is the manual entry method. For parallel flue ducts larger than 40 centimeters square, manual drilling can be carried out for cleaning. Attention needs to be paid to strengthening ventilation and equipping it with low-voltage (36V) lighting power supply.

人工無法進入時采用此法，即拆卸法，當煙道小于40公分見方時。安裝清洗人員根據現場實際情況，每隔一定間隔拆卸一段煙道向兩方延伸清理，此法效果好，難度較大，用度較高。

When manual entry is not possible, this method, also known as disassembly method, is used when the flue is less than 40 centimeters square. According to the actual situation on site, the installation and cleaning personnel dismantle a section of flue at regular intervals and extend it to both sides for cleaning. This method is effective, difficult, and expensive.

安裝清洗人員采用專用無火花開孔工具將管道的一方或多方開孔，即開孔法，此法對于人工無法進入且拆卸較為難題的煙道采用此法。開孔大小間隔數目根據現場情況而定，油污清理完后將管道密封復原。

The installation and cleaning personnel use a dedicated spark free drilling tool to drill one or more holes in the pipeline, which is called the drilling method. This method is used for flues that cannot be accessed manually and are difficult to disassemble. The size and number of intervals for opening holes depend on the on-site situation. After cleaning the oil stains, the pipeline seal should be restored.

清洗周期短的煙道采用此法清理，即機器設備清洗法，對于油污較少。先將管道內噴灑清洗劑，使油污軟化，再用30米長的電動軟軸刷將油污洗擦干凈。此法使用于30公分見方的豎煙道，人工無法進入且不便拆卸的隱蔽的小煙道。這種不易清洗而且輕易積油要縮短清洗周期。

The flue with a short cleaning cycle is cleaned using this method, namely machine equipment cleaning method, which has less oil pollution. First, spray cleaning agent inside the pipeline to soften the oil stain, and then use a 30 meter long electric flexible shaft brush to clean the oil stain. This method is used for vertical flues measuring 30 centimeters square, hidden small flues that cannot be manually accessed and cannot be dismantled. This type is not easy to clean and easily accumulates oil, which needs to shorten the cleaning cycle.

Through the above sharing, I believe many friends have gained a similar understanding of kitchen smoke exhaust pipes. Kitchen smoke exhaust pipes are also becoming increasingly popular in our daily lives, because kitchen smoke exhaust pipes can not only prevent the disorderly discharge of oil fumes from affecting residents downstairs, but also prevent the backflow of oil fumes. But now there are still many friends who are not very familiar with kitchen smoke exhaust pipes, and even do not know how to install and choose kitchen smoke exhaust pipes. We hope that in the future, if you encounter unfamiliar places with kitchen smoke exhaust pipes, you can pay more attention to our shared content.
