How to install and clean the kitchen smoke exhaust pipeline

With the continuous improvement of people's living standards, people have higher and higher requirements for home decoration, especially the kitchen decoration now. Many residents of high-rise residential buildings report that cooking upstairs will lead to smoke billowing downstairs, which will have a great impact on people's lives. Therefore, in view of this situation, the kitchen smoke exhaust pipe appeared. Kitchen smoke exhaust pipe can not only prevent smoke from being discharged randomly, but also be very convenient to use and install. But many friends are not very familiar with the smoke exhaust pipe in the kitchen, so Bian Xiao will tell you about the smoke exhaust pipe in the kitchen.

Kitchen flue installation

First, the auxiliary flue must be preserved.

Every kitchen has a flue, and at the same time, the flue also has the main and auxiliary points. The main flue runs through the whole building and the auxiliary flue is relatively independent. Generally, the lampblack at home will go to the auxiliary flue first, and then enter the main flue through the hole in the partition, so as to ensure that the lampblack of every household is isolated. However, if the auxiliary flue is directly connected with the main flue, it will lead to the phenomenon of backward smoke or cross smoke due to too low pressure.

Second, the construction details should pay attention to the problem

First of all, it is very important to choose the installation position of the range hood. The shorter the pipe, the better. Some owners will pull the pipe longer for the sake of beauty. After turning off the range hood in this way, there will be a lot of oil smoke in the pipeline that can't be discharged and then poured back indoors. In addition, in order not to destroy the original main and auxiliary flue, its opening direction cannot be changed at will, and it must be drilled in the auxiliary flue.

Third, pay attention to safety when opening the window to smoke.

In order to avoid the problem of smoke crosstalk, some owners gave up the original flue and directly opened holes in the windows to smoke. This is ok, but there are a few points to pay attention to.

First of all, before opening a hole in a window or wall, it must be approved by the property; Secondly, pay attention to safety issues. Generally, the end of the exhaust pipe is metal. If the hole is too small, the metal heat transfer may cause the glass to burst and hurt pedestrians, and the smoke exhaust pipe will lead out of the window, and the strong north wind blowing head-on will lead to the backflow of oil smoke. It is best to extend the pipeline and nest it downward, so as to prevent rainwater from flowing into the pipeline when it rains, and to keep the windshield out.

Four, check valve door often change.

If the auxiliary flue has been removed, or it is necessary to better prevent the flue gas from falling back, then use the flue check valve. In general, the function of the check valve of the range hood is not obvious, but installing the check valve in the flue can protect the range hood, so that the flue gas in the flue will not flow back to the pipeline and the range hood. However, after installing the check valve, it should be cleaned regularly, otherwise it will make the check valve open and lose its function. It is best to replace the flue check valve every two years or so.

How to clean the kitchen smoke exhaust pipe

1, the installation and cleaning personnel will first dismantle the upper and lower sections of the pipeline, that is, the airborne method, which is mainly used to clean the vertical flue with a width of more than 50 cm. Secure the safety rope at high altitude 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 dangerous, technical, expensive and effective. Because vertical flue generally has less oil accumulation, it can be cleaned once a year.

2. This way is labor-intensive, that is, the way of manual entry. Parallel flue larger than 40 cm square can be cleaned by manual drilling. Need to pay attention to strengthen ventilation, equipped with low-voltage (36V) lighting power supply.

3. When it is impossible to enter manually, that is, when the flue is less than 40 square centimeters, this method is adopted. According to the actual situation on site, the installation and cleaning personnel remove a section of flue at regular intervals and extend it to both sides for cleaning. This method is effective, difficult and costly.

4. The installation and cleaning personnel tap one or more sides of the pipeline with a special spark-free tapping tool, that is, tapping method, which is used for the flue that is inaccessible and difficult to disassemble by hand. The size, interval and number of openings depend on the site conditions, and the pipeline will be sealed and repaired after the oil pollution is cleaned.

5. The flue with short cleaning cycle is cleaned by this method, that is, the cleaning method of mechanical equipment, with less oil pollution. Spray a cleaning agent into the pipeline to soften the oil stain, and then use a 30-meter-long electric flexible shaft brush to clean the oil stain. This method is used for vertical flue of 30 cm square and concealed small flue which is inaccessible and inconvenient to disassemble. This kind of oil is not easy to clean, easy to accumulate, and the cleaning cycle should be shortened.

Through the above sharing, I believe many friends also know the knowledge of kitchen exhaust pipes. Kitchen smoke exhaust pipes are becoming more and more popular in our lives, because kitchen smoke exhaust pipes can not only prevent the fumes from affecting the residents downstairs, but also prevent the fumes from being discharged back. However, there are still many friends who don't know much about kitchen smoke exhaust pipes, and even don't know how to install and choose kitchen smoke exhaust pipes. I hope that when you meet unfamiliar places in your future life, you can pay more attention to what we share.
