1, artificial entry method: greater than 40 centimeters square parallel flue can be manually drilled in to clean up, this method is more labor-intensive, need to pay attention to strengthen the ventilation, equipped with low-voltage (36-volt) lighting power supply.

2, dismantling method: when the flue is less than 40 centimeters square, the manual inaccessible when using this method. This method is the most thorough, the best cleaning effect of cleaning, but the construction is difficult, the amount of workers is also large, while the cost is relatively high. Flue cleaning program is: technicians according to the actual situation of the flue, measured every certain distance to dismantle a section of the flue and extend the cleaning in both directions to ensure that the cleaning is thorough, to ensure the quality of cleaning.

3, open hole method: this method is relatively easy compared to the demolition method, the cost is relatively low, for manual inaccessible and more difficult to dismantle the flue using this method, measured by the technicians need to open the holes in the distance between the intervals, the location of open holes, the size and number of holes through these holes in the flue flue cleaning. Finally, each hole is sealed.

4, machine and equipment cleaning method: this method is the easiest to operate, the least difficult, the smallest amount of work, the lowest cost of flue cleaning, for less oil, cleaning cycle of the short flue using this method of cleaning, first of all, the pipe will be sprayed with cleaning agent, so that the oil is softened, and then 30 meters long motorized flexible axle brush will be brushed clean of oil. This method is used in 30cm square vertical flue, artificial inaccessible and inconvenient to dismantle the hidden small flue. This is not easy to clean and easy to accumulate oil to shorten the cleaning cycle.

5, airborne method: this method is mainly used to clean more than 50 centimeters square vertical flue, technicians first remove the top and bottom cut off the pipe, in the flue above the fixed high-altitude safety rope, fastened with a seat belt, technicians from top to bottom cleaning vertical flue oil. This method is more dangerous, technical, expensive and effective. As the vertical flue is generally less oil accumulation can be cleaned once a year.

Oil pipe cleaning notes:

1, vertical pipe

(1) first do a good job under the vertical pipe construction of the preparatory work, the construction personnel shall only be qualified to operate at high altitude, and fasten the safety belt, wearing a helmet with a top light. Another air pressure pump is equipped with an air pressure pump, in order to prepare for the construction personnel in the vertical pipe to keep the air free.

(2) after all the preparatory work is ready, the construction personnel into the vertical pipe to shovel oil on the pipe wall, the oil shoveling and then use a strong degreasing agent on the pipe wall oil treatment, to the bottom of the vertical pipe, the construction personnel will be to the remaining garbage and received to shovel the oil bucket, and then by the roof of the roof construction personnel with a safety rope to the roof, and put the garbage into the garbage bag, in order to be ready for checking.

2, cross-pipe:

(1) set up a ladder.

(2) Two workers go up the ladder in order, the worker puts the 36V low voltage lamp into the pipe and puts the garbage container of liquid oil into the pipe.

(3) After entering the pipeline, first use the spatula to shovel the oil inside the pipeline, put it into the dumpster, and when all the oil is shoveled clean, then wipe the inside of the pipeline with the agent, and then take the dumpster out of the pipeline.

(4) after the construction, the use of raw materials on the pipeline pipe reset, and pipeline sealing treatment, restore the original state, and do a good job of construction personnel safety measures. Mesh cover cleaning: first unload the mesh cover, soak it with medicated water, and then rinse it with high pressure cleaner, and then press fit it back. Cover cleaning: first use the spatula to cover the surface of the oil shovel clean, and then rinse with a high-pressure cleaner, and then loaded back in accordance with the original shape, and do cover surface maintenance. After the project is completed, the cleaning personnel will clean up the site and pull the oil and other garbage out of the company. Thoroughly remove the oil in the kitchen piping to prevent fire.
