Cleaning method of oil fume pipeline
1, manual entry method:
For parallel flue larger than 40 cm square, it can be cleaned by manual drilling. This method is labor-intensive, so it is necessary to strengthen ventilation and equip with low-voltage (36V) lighting power supply.
2. Disassembly method:
When the flue is less than 40 square centimeters, this method is used when it is impossible to enter manually.
This method is the most thorough and best cleaning method, but it is difficult to construct, requires a lot of workers, and the cost is relatively high. The scheme of flue cleaning is: according to the actual situation of 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.
3. Opening method:
Compared with the disassembly method, this method is relatively easy and low cost. This method is used for the flue which cannot be accessed manually and is difficult to disassemble. Technicians can calculate the spacing distance, opening position, size and number of holes, and then clean the flue through these holes. Finally, each hole is sealed.
4, mechanical equipment cleaning method:
This method is the easiest to operate, the least difficult, the least workload and the lowest cost. For the flue with less oil pollution and short cleaning cycle, this method is used for cleaning. Spray cleaning agent in the pipeline to soften the oil stain, and then scrub the oil stain with a 30-meter-long electric flexible shaft brush. This method is used for vertical flue of 30 cm square and concealed small flue which is inaccessible and inconvenient to disassemble. This kind is not easy to clean, easy to accumulate oil, and the cleaning cycle should be shortened.
5. Airborne method: This method is mainly used to clean the vertical flue over 50 square centimeters. Technicians first remove the upper and lower sections of the pipeline, fix the overhead safety rope above the flue and fasten the safety belt. Technicians clean up the oil in the vertical flue from top to bottom. This method is dangerous, technical, expensive and effective. Because vertical flue generally has less oil accumulation, it can be cleaned once a year.
The cleaning process of oil fume pipeline (horizontal pipeline and vertical pipeline) is as follows:
1, the staff should change their work clothes, wear protective glasses and masks, and fasten their seat belts.
2. Riser
(1) First, prepare for the construction of the lower riser. Construction personnel must be qualified for aerial work, fasten safety belts and wear safety helmets with overhead lights. In addition, an air pressure pump is provided for the construction personnel to keep the air flowing in the riser.
(2) After all the preparations are ready, the construction personnel enter the riser to shovel oil on the pipe wall, and then clean the pipe wall with a powerful degreasing agent. After reaching the bottom of the vertical pipe, the construction workers will put the remaining garbage into the bucket, and then the roof construction workers will lift it to the roof with safety ropes, and put the garbage into garbage bags for inspection.
3. Horizontal tube
(1) Set up a ladder.
(2) Two workers climb the ladder in turn, and the workers put the 36V low-voltage lamp into the pipeline and the trash can of liquid oil into the pipeline.
(3) After entering the pipeline, shovel out the oil in the pipeline with a shovel and put it into the garbage bin. After all the oil stains are shoveled clean, wipe the pipeline with chemicals, and then take the trash can out of the pipeline.
(4) After the construction, reset the pipeline with raw materials, seal the pipeline, restore the original state, and take safety measures for the construction personnel.
Cleaning the net cover: first remove the net cover, soak it in medicinal liquid, then rinse it with a high-pressure cleaning machine and put it back.
Cleaning of the cover: firstly, scrape the oil on the surface of the cover with a scraper, then rinse it with a high-pressure cleaning machine, and then put it back in its original place as it is, so as to maintain the surface of the cover.
After the project construction is completed, the cleaning staff will clean up the site and pull out the company's oil pollution and other garbage.
Thoroughly remove oil stains from kitchen pipes to prevent fire.
Principle of cleaning oil fume pipeline
Because of the working principle of oil fume pipeline, the flue should be cleaned frequently during our use. During the use of the oil fume pipeline, there will be a lot of oil stains left on the surface of the hood and flue, which will form oil stains after a long time, so it is very troublesome for us to remove the oil stains when cleaning. The generation of oil dirt will seriously affect the use of lampblack machine and lampblack pipeline, which makes it more difficult to remove lampblack due to poor circulation.
Cleaning the oil fume pipeline is very troublesome. The following are some methods I introduced to clean the oil fume pipeline, hoping to help everyone.
Cleaning standard of lampblack pipeline
The cleaning standards for oil fume pipes are as follows: after cleaning the fume hood flue, 90% of the original inner wall of the flue can be seen without blockage and stubborn oil pollution; The surface of the stove is clean and bright; 90% can see the surface of the fan impeller; There is no precipitated oil stain at the bottom of the motor; There is no oil pollution and stubborn oil pollution outside the pipeline. The above is my introduction to the cleaning methods and key cleaning places of the oil fume pipeline, hoping to help those who want to clean the oil fume pipeline.
