1. Cleaning method of oil fume pipeline

1. Ordinary consumers can clean the small oil fume pipeline with kitchen cleaner at home, and the large oil fume pipeline must be cleaned by professionals entering the flue.

2. If the smoke outlet is too narrow for manual access to the flue, or the flue cannot be cleaned because it is too narrow for manual access, but there are major hidden dangers, a high-pressure water gun can be used to clean it with cleaning agent or caustic soda, and then hydrochloric acid can not be used to clean it, 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 it is difficult to construct, requires a large number of workers and costs relatively high.

3. Cleaning scheme

1) According to the actual situation of flue, technicians estimate that a section of flue should be dismantled at regular intervals and extended in two directions to ensure thorough cleaning and quality.

2) opening method: this method is relatively easy and relatively low in cost compared with the disassembly method, but the cleaning effect is relatively poor. The specific method is: technicians calculate the interval distance, position, size and number of holes to be opened, and clean the flue through these holes. Finally, each hole is sealed.
