Cleaning method of kitchen oil fume exhaust pipe

1. Dismantling method This method is the most thorough and the cleaning effect is the best way, but the construction is difficult, the number of workers is large, and the cost is relatively high. The cleaning scheme is: according to the actual situation of the pipeline, the technicians calculate that a section of the pipeline should be dismantled at regular intervals and extended in two directions for cleaning, so as to ensure that the cleaning quality is checked by the construction team leader to be clean and free from oil pollution before installation.

2. Opening method This method is relatively easier and cheaper than disassembly method, but the cleaning effect is relatively poor. The concrete method is as follows: technicians calculate the interval distance, position, size and number of holes to be drilled, and clean the pipeline through the holes; Finally, each hole is sealed.

3. Mechanical equipment method This method is the easiest to operate, the least difficult and workload, and the lowest cost, but the cleaning effect is also the worst. However, for vertical pipes with a cleaning cycle of less than half a year, this cleaning method is undoubtedly the best choice. The concrete method is as follows: the oil stain of the oiling agent is sprayed inward at the upper end of the vertical pipeline, and it will automatically slide down to the horizontal pipeline, and the construction personnel will clean it at the same time during the operation.
