What are the cleaning methods of oil fume exhaust pipe in hotel kitchen?

Professionals enter the flue for cleaning. For those who can't enter the flue manually due to the narrow smoke outlet, or can't be cleaned because of the narrow flue, but there are major hidden dangers, high-pressure water guns can be used to clean with cleaning agents or caustic soda, and hydrochloric acid is not allowed, leaving no dead ends. If hydrochloric acid is used, it must be washed with clear water immediately. This method is the most thorough and best cleaning method, but the construction is difficult, the amount of workers is large, and the cost is relatively high.

The cleaning scheme is: according to the actual situation of the 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.

2 Opening method is easier and cheaper than disassembling method, but the cleaning effect is poor.

The specific method is: technicians calculate the interval distance, position, size and the number of holes to be opened, and clean the flue through these holes. Finally, each hole is sealed.
