　　It is very important to clean the soot purifier correctly because the grease and dirt on the soot purifier are flammable and difficult to remove. If the user uses flammable and explosive chemical solvent to clean, improper operation may cause fire. Using neutral detergent to clean the surface of lampblack purifier usually adopts the following steps:

　　1. 擰開油杯倒油。

　　1. Turn on the oil cup and pour the oil.

　　2. 取下過濾器，用中性洗滌劑浸泡在溫水中，用軟毛刷清洗干凈;

　　2. Remove the filter, soak it in warm water with neutral detergent, and clean it with soft brush.

　　3.用中性清潔劑浸泡過的濕布擦洗身體表面。要注意的是，清洗時一定要拔出電源插頭;請勿用水沖洗，以免電腦板進水。不要使用易燃清潔劑。

　　3. Scrub the body surface with a wet cloth soaked with neutral detergent. It should be noted that the power plug must be pulled out when cleaning; do not flush with water to prevent the computer board from entering water. Do not use flammable detergents.

　　油煙凈化器的清洗過程對油煙管的清洗也是非常重要的。清洗垂直煙道的方法有兩種:

　　The cleaning process of lampblack purifier is also very important for the cleaning of lampblack pipe. There are two ways to clean vertical flues:

　　1. 開孔方式:由技術人員計算開孔間距、開孔位置、開孔大小、開孔數量，并對通過開孔的煙道進行清洗。后，每個孔都是密封的。這種方法比較困難，比較昂貴，但是清洗效果非常有效。

　　1. Opening mode: The technicians calculate the spacing, location, size and number of openings, and clean the flue through the openings. Finally, each hole is sealed. This method is more difficult and expensive, but the cleaning effect is very thorough.

　　2. 機械設備方法:向煙道內噴油分散劑后，用高壓清洗機清洗。這種方法是簡單、不困難、工作量少、清洗成本低的方法，但對于清洗周期為6個月或更少的垂直煙道來說，這種清洗方法無疑是好的選擇。

　　2. Mechanical equipment method: After spraying oil dispersant into flue, it is cleaned by high-pressure cleaning machine. This method is the simplest, least difficult, less workload and lowest cleaning cost method, but for vertical flue with a cleaning cycle of 6 months or less, this cleaning method is undoubtedly the best choice.
