Kitchen smoke exhaust pipe will accumulate a lot of dirt for a long time, which will not only affect the smoke exhaust effect, sometimes because of excessive temperature, there will be fire.
1, the installation of cleaning personnel first remove the top section of the pipeline and the most inferior section, that is, airborne method, this method is mainly used for cleaning 50 cm square above vertical flue. Above the flue, secure the aerial safety rope, fasten the seat belt and install the cleaning personnel to clean the oil in the vertical flue from top to bottom. This method is more dangerous, more technical, higher cost and better cleaning effect. Because the vertical flue generally less oil, once a year can be cleaned.
2, this method of labor intensity is larger, that is, artificial access law, for more than 40 cm square parallel flue, you can drill into the clean-up. Need to pay attention to strengthen ventilation, equipped with low-voltage (36 volts) lighting power supply.
3, the artificial can not enter the use of this method, that is, demolition method, when the flue is less than 40 cm square. Installation and cleaning personnel according to the actual situation at the scene, at intervals of a section of flue removal, cleaning to the two sides, the effect of this method is good, more difficult, higher cost
4. The installation and cleaning personnel use a special spark hole opening tool to open one or more sides of the pipe, that is, the opening method. This method is used for the flue which can not enter and disassemble more difficult. The size, spacing and number of the holes are determined according to the conditions of the field. After the oil is cleaned, the pipes are sealed and restored.
5, cleaning cycle short flue using this method of cleaning, namely machine equipment cleaning method, for less oil pollution. The pipeline will be sprayed cleaning agent, so that oil softening, and then 30 meters long electric flexible brush to wash oil clean. This method is used in the vertical flue of 30 cm square, which can not be entered and can not be removed. This is not easy to clean and easy to accumulate oil, shorten the cleaning cycle.
