专注通风管道加工·排烟罩

1.安装清洗人员先将管道上下两段拆除，即空中法，主要用于清洗直径50 cm见方以上的垂直烟道。在烟道上方系好高空绳，系好带，并安装清扫人员自上而下清扫垂直烟道内的油污。这种方法是危险的，技术的，经济的，有效的。因为立式烟道一般积油少，一年清洗一次即可。

1. The installation and cleaning personnel first remove the upper and lower sections of the pipeline, namely the air in method, which is mainly used to clean vertical flues with a diameter of 50 cm or more. Tie the high-altitude safety rope above the flue, fasten the safety belt, and install cleaning personnel to clean the oil stains inside the vertical flue from top to bottom. This method is dangerous, technical, economical, and effective. Because vertical flues generally have less oil accumulation, they can be cleaned once a year.

2.这种方法劳动强度大，也就是手工录入的方法。对于大于40平方厘米的平行烟道，可以手动钻孔清理。需要注意加强通风，配备低压(36V)照明电源。

2. This method is labor-intensive, which is a manual input method. For parallel flue ducts larger than 40 square centimeters, manual drilling and cleaning can be performed. Attention should be paid to strengthening ventilation and equipping low-voltage (36V) lighting power supply.

3.当烟道小于40 cm见方时，用这种方法，即拆卸法。清扫人员根据现场实际情况，每隔一段时间拆除一段烟道，延伸到两侧进行清扫。这种方法效果好，难度大，费用高。

When the flue is less than 40 cm square, use this method, which is the disassembly method. According to the actual situation on site, the cleaning personnel will dismantle a section of flue every once in a while and extend it to both sides for cleaning. This method is effective, difficult, and costly.

4.安装清洗人员使用专用的无火花攻丝工具对一根或多根管道进行攻丝，即攻丝法，用于手动无法接近且难以拆卸的烟道。开口的大小、间隔和数量根据现场条件确定。油污清理完毕后，对管道进行封闭和修复。

4. The installation and cleaning personnel use specialized spark free tapping tools to tap one or more pipes, known as the tapping method, for manually inaccessible and difficult to disassemble flues. The size, spacing, and quantity of openings are determined based on site conditions. After cleaning the oil stains, seal and repair the pipelines.

5.清洗周期短的烟道用这种方法清洗，即机械设备的清洗方法，油污少。向管道内喷入清洗剂软化油污，然后用30米长的电动软轴刷清洗油污。这种方法用于30厘米见方的垂直烟道，不能手动进入，也不能拆卸。这种不容易清洗，容易积油，清洗周期要缩短。

5. The flue with a short cleaning cycle can be cleaned using this method, which is a mechanical equipment cleaning method with less oil pollution. Spray cleaning agent into the pipeline to soften the oil stains, and then use a 30 meter long electric soft shaft brush to clean the oil stains. This method is used for vertical flues measuring 30 centimeters square and cannot be manually entered or disassembled. This type is not easy to clean, prone to oil accumulation, and the cleaning cycle needs to be shortened.
