The exhaust pipe of kitchen oil fume purifier will accumulate a lot of dirt due to long-term use, which not only affects the purification effect of oil fume purifier, but also sometimes causes fire due to excessive temperature. Then it is necessary to clean the exhaust pipe of the kitchen fume purifier. Under normal circumstances, it should be cleaned once every three to five months, but how to clean the pipeline of the lampblack purifier? Next, pulse environmental protection will give you a brief introduction: the installation and cleaning personnel will first remove the top and bottom sections of the pipeline, that is, in the air, which is mainly used to clean the vertical flue over 50 cm square. Secure the safety rope at high altitude above the flue, fasten the safety belt, and install the cleaning personnel to clean the oil in the vertical flue from top to bottom. This method is dangerous, technical, expensive and effective. Because vertical flue generally has less oil accumulation, it can be cleaned once a year. This method is labor-intensive, that is, manual entry method, and parallel flue larger than 40 cm square can be cleaned by manual drilling. Need to pay attention to strengthen ventilation, equipped with low-voltage (36V) lighting power supply.

This method is used when manual access is impossible, that is, when the flue is less than 40 square centimeters. According to the actual situation on site, the installation and cleaning personnel remove a section of flue at regular intervals and extend it to both sides for cleaning. This method is effective, difficult and costly. Installation and cleaning personnel use special spark-free tapping tools to tap one or more sides of the pipeline, that is, tapping method, which is used for manually inaccessible and difficult to disassemble flue. The size, interval and number of openings depend on the site conditions, and the pipeline will be sealed and repaired after the oil pollution is cleaned. The flue with short cleaning cycle is cleaned by this method, that is, the cleaning method of mechanical equipment, which has less oil pollution. Spray a cleaning agent into 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 flue of 30 cm square and concealed small flue which is inaccessible and inconvenient to disassemble. This kind of oil is not easy to clean, easy to accumulate, and the cleaning cycle should be shortened.
