1、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。

　　1. The installation and cleaning personnel use a special spark hole opening tool to open one or more sides of the pipe, that is, the opening method. This method is used for the flue which can not enter and disassemble more difficult. The size, spacing and number of the holes are determined according to the conditions of the field. After the oil is cleaned, the pipes are sealed and restored.

　　2、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。

　　2, this method of labor intensity is larger, that is, artificial access law, for more than 40 cm square parallel flue, you can drill into the clean-up. Need to pay attention to strengthen ventilation, equipped with low-voltage (36 volts) lighting power supply.

　　3、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。油煙凈化器

　　3, cleaning cycle short flue using this method of cleaning, namely machine equipment cleaning method, for less oil pollution. The pipeline will be sprayed cleaning agent, so that oil softening, and then 30 meters long electric flexible brush to wash oil clean. This method is used in the vertical flue of 30 cm square, which can not be entered and can not be removed. This is not easy to clean and easy to accumulate oil, shorten the cleaning cycle.

　　4、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

　　4, the artificial can not enter the use of this method, that is, demolition method, when the flue is less than 40 cm square. Installation and cleaning personnel according to the actual situation at the scene, at intervals of a section of flue removal, cleaning to the two sides, the effect of this method is good, more difficult, higher cost

　　5、安裝清洗人員先拆下管道的上截和下截，即空降法，此法主要用于清洗50公分見方以上的豎煙道。煙道上方固定高空繩，系上帶，安裝清洗人員從上下清洗豎煙道內的油污。

　　5, the installation of cleaning personnel first remove the top section of the pipeline and the most inferior section, that is, airborne method, this method is mainly used for cleaning 50 cm square above vertical flue. Above the flue, secure the aerial safety rope, fasten the seat belt and install the cleaning personnel to clean the oil in the vertical flue from top to bottom.

　　此法危險性較大，技術性強，用度較高，清理效果好。因為豎煙道一般積油較少一年清洗一次即可。

　　This method is more dangerous, more technical, higher cost and better cleaning effect. Because the vertical flue generally less oil, once a year can be cleaned.
