What are the steps of the method for cleaning the smoke exhaust pipe?

The installation and cleaning personnel first remove the top and bottom sections of the pipeline, that is, the airborne method, which is mainly used to clean the vertical flue above 50 cm square. Fix the high-altitude safety rope above the flue, fasten the safety 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, more useful, and has a good cleaning effect.

Because the vertical flue generally has less oil accumulation, it can be cleaned once a year. This method is more labor-intensive, that is, the manual entry method, for the parallel flue larger than 40 cm square, it can be manually drilled into for cleaning. Attention should be paid to enhancing ventilation and equipping it with a low-voltage (36 volt) lighting power supply.

This method is used when manual access is not possible, that is, the disassembly method, when the flue is less than 40 cm square. According to the actual situation of the site, the installation and cleaning personnel dismantle a section of flue at certain intervals to extend and clean in both directions, and this method has a good effect, is more difficult, and has a higher degree of use. The installation and cleaning personnel use a special non-spark opening tool to open one or more sides of the pipeline, that is, the opening method, which adopts this method for the flue that cannot be entered manually and is difficult to disassemble.

The size, interval and number of openings are determined according to the site conditions, and the pipeline seal is restored after the oil pollution is cleaned. The first thing is to choose the right location to install. The location of the kitchen smoke exhaust pipe has a lot to do with the length of the pipe.

For the sake of aesthetics, many home owners will ask the installer to stretch the pipe very long. In fact, in this way, it is easy to make the oil smoke in the pipe unable to discharge. Install ventilation ducts.

The ventilation duct installation first finds the elevation, uses an electric drill to punch the wall hole, and cooperates with the reserved bracket hole to bury the lifting bracket; The assembled air duct is leveled and aligned, and then fixed with fastening bolts. If it is the installation of ventilation and smoke exhaust pipes, the ventilation ducts and smoke exhaust pipes should be separated, the ventilation direction and location of the two are different, and the air quality of circulation is better than the latter, so the same pipe cannot be used. There are generally two types of ventilation ducts: round and rectangular, if it is a round duct, it is based on the average diameter.

The smoke exhaust pipe is composed of horizontal pipes, vertical pipes and elbows, the pipeline should be separated from the construction when cleaning, the traditional construction scheme is to manually enter the cleaning and dismantling and cleaning, these construction methods are time-consuming, require a large amount of labor, and are extremely unsafe, Qizhi environmental protection technology **** adopts robot operation cleaning, and the robot first enters the pipeline to spray special strong oil smoke to remove the oil, so that the oil smoke attached to the pipeline is softened and peeled, and then the high-pressure cleaning robot is used to enter the pipeline for steam high-pressure cleaning. In this way, the cleaning can achieve a 360-degree cleaning effect without dead angles, which not only saves man-hours, reduces construction intensity, but also is safe.

The cleaning process of the oil fume pipeline is: preparing to clean the belt supplies, installing the pipeline cleaning equipment, preparing before cleaning, cleaning, and maintaining the cleaned pipeline.

1. Prepare cleaning supplies.

It is best to use a special cleaning agent for cleaning supplies. Cleaning agents come in different grades, from extremely corrosive to mild. Choosing a milder cleaner can show concern for the environment and protection of the equipment.

Also prepare tools such as gloves, protective mask, brushes, cleaning cloths, etc.

2. Install pipeline cleaning equipment.

Before proceeding with cleaning, pipe cleaning equipment is first installed. This can be done by taking over the air intake into the fume duct. The equipment should be able to spray the inside of the pipe with cleaning agent and the amount of cleaning agent sprayed can be controlled.

3. Preparation before cleaning.

Pipes must be inspected before cleaning work can be carried out. Special inspection tools, such as video cameras or thermal imaging cameras, can be used to check for grease and grime build-up. If there is, you can use a professional slag vacuum cleaner or pusher to gently clean it.

4. Clean.

The method of cleaning is to spray a mild cleaning agent on the inside of the pipe. Use safety precautions such as gloves and a face shield when using cleaning agents. Spray the cleaner on top of the pipe to ensure that the spray is even. Wait for some time before rinsing with water.

5. Maintain the cleaned pipeline.

After cleaning, make sure the pipes are dry. Because damp pipes will attract dust and dirt more easily, etc. Next, you can spray the surface of the pipe with a preservative. The use of preservatives can extend the life of the pipe.

The process of cleaning the oil fume pipe. It is broken down into the following steps:

1.First, clean up the solid substances such as carbon deposits and dirt in the oil smoke pipe.

2.Tools such as high-pressure water guns are fed into the pipes to completely remove grease, dirt, and bacteria from the pipes.

3.Use professional cleaning agents and equipment to disinfect the inside of the pipes and kill bacteria.

4.Conduct a water discharge test to ensure that the effluent in the pipe can pass smoothly.

5.Carry out anti-corrosion treatment of pipelines to prevent secondary pollution. The above is the basic process of cleaning the fume pipe, which can effectively ensure the hygiene of the kitchen type and prevent the harm of the fume to the human body. Shut up.

1. The staff should change into work clothes, wear protective glasses and masks, and fasten seat belts. Imitation defeat.

2. a standpipe. 1) First make the preliminary preparations for the construction of the lower riser, and the construction personnel must only have the qualification of high-altitude operation, fasten the safety belt, and wear a safety helmet with a top light. In addition, it is equipped with an air pressure pump to prepare the construction personnel to keep the air flowing in the vertical pipe.

2) After all the preparations are ready, the construction personnel enter the vertical chan pipe to shovel the oil on the pipe wall, shovel the oil and then use a strong degreaser to clean the oil on the pipe wall, to the bottom of the vertical pipe, the construction personnel will receive the remaining garbage together with the shovel oil barrel, and then the roof construction personnel with a safety rope to the roof, and put the garbage into the garbage bag for inspection.

3. a transverse pipe. 1) Set up a ladder.

2) Two workers go up the ladder in turn, the workers put the 36v low-voltage lamp into the pipeline, and put the garbage bin of liquid oil into the pipeline.

3) After entering the pipeline, first use a shovel to clean the oil inside the pipeline, put it into the garbage can, and then wipe the inside of the pipeline with a medicant, and then take the garbage can out of the pipeline.

4) After the construction is completed, the pipeline is reset with raw materials, and the pipeline is sealed, restored to the original state, and the safety measures of the construction personnel are done.

Mesh cleaning: Remove the grille first, soak it in medicated water, then rinse it with a high-pressure cleaner, and then press it back.

Cover cleaning: first use a shovel to clean the oil on the surface of the cover, then rinse it with a high-pressure cleaner, and then install it back as it is, and do the surface curing.

After the construction of 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 oil from kitchen pipes to prevent fires.

1.Prepare tools and materials: detergent, brushes, gloves, masks, rags, buckets, etc.

2.Close the range hood and gas valves, and remove the oil mesh and oil cup of the range hood. 3.

Remove the air inlet and outlet of the fume pipe, and clean the inside of the pipe with a brush. 4.Pour the cleaner into a bucket of water, dip the brush into the cleaner, start at the air inlet, and brush along the pipe.

5.After brushing, rinse the inside of the pipe with clean water until the water runs out cleanly. 6.

Wipe the inside and outside of the pipe with a rag and reinstall the pipe. 7.After cleaning, clean the oil mesh and the crude oil cup and reinstall it on the oil worm smoke machine.

8.Open the gas valve and range hood to test whether the range hood is working properly. 9.

After cleaning, clean the tools and materials of the stuffy stool to keep it clean and hygienic.
