What is the cleaning method of kitchen oil fume pipeline?

For parallel flue larger than 40 cm square, it can be cleaned by manual drilling. This method is labor-intensive, so it is necessary to strengthen ventilation and equip with low-voltage (36V) lighting power supply.

2. Disassembly method:

When the flue is less than 40 square centimeters, this method is used when it is impossible to enter manually.

This method is the most thorough and best cleaning method, but it is difficult to construct, requires a lot of workers, and the cost is relatively high. The scheme of flue cleaning is: according to the actual situation of flue, technicians calculate that a section of flue should be removed at regular intervals and extended in two directions to ensure thorough cleaning and cleaning quality.

3. Opening method:

Compared with the disassembly method, this method is relatively easy and low cost. This method is used for the flue which cannot be accessed manually and is difficult to disassemble. Technicians can calculate the spacing distance, opening position, size and number of holes, and then clean the flue through these holes. Finally, each hole is sealed.

4, mechanical equipment cleaning method:

This method is the easiest to operate, the least difficult, the least workload and the lowest cost. For the flue with less oil pollution and short cleaning cycle, this method is used for cleaning. Spray cleaning agent in the pipeline to soften the oil stain, and then scrub the oil stain with a 30-meter-long electric flexible shaft brush. This method is used for vertical flue of 30 cm square and concealed small flue which is inaccessible and inconvenient to disassemble. This kind is not easy to clean, easy to accumulate oil, and the cleaning cycle should be shortened.

5. Airborne method: This method is mainly used to clean the vertical flue over 50 square centimeters. Technicians first remove the upper and lower sections of the pipeline, fix the overhead safety rope above the flue and fasten the safety belt. Technicians clean up 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.
