Common problems of smoke exhaust pipe installation

  • Detail

The smoke exhaust pipe should be cleaned frequently. If it is not cleaned for a long time, a lot of dirt will accumulate, which will not only affect the smoke exhaust effect, but also cause fire sometimes due to high temperature

with the development of society, the kitchens of many family houses emit lampblack from their own windows, resulting in cooking downstairs and smoking upstairs. Therefore, when decorating the family, the kitchen flue decoration is very important. Once it is unreasonable, it will cause a taste reversal phenomenon and affect the home life. Therefore, next, the editor will introduce common problems in the installation of smoke exhaust pipes and how to clean the smoke exhaust pipes in the kitchen

common problems in the installation of smoke exhaust pipes

1. The auxiliary flue must be kept

every kitchen has a flue. At the same time, the flue also has the main and auxiliary parts. The main flue runs through the whole building, while the auxiliary flue is relatively independent. Generally, the lampblack in the home will go to the auxiliary flue first, and then enter the main flue through the hole on the bulkhead, so as to ensure that the lampblack of each household is isolated

2. Pay attention to the construction details.

the installation position of the range hood is very important. The shorter the pipe, the better. In order not to damage the original main and auxiliary flue, the opening direction can not be changed at will, but must be placed in the auxiliary flue

3. Pay attention to the safety of smoke exhaust from windows

first, the consent of the property must be obtained before opening windows or walls; Secondly, pay attention to safety. Generally, the end of the smoke exhaust pipe is made of metal. It is best to stretch out the pipe and then nest it down. In this way, it can also avoid the rain water flowing into the pipe when it rains and keep the wind shield outside

4. Frequently replace the check valve

if the auxiliary flue has been removed, or the effect of preventing smoke pouring is better, then use the flue check valve. After installing the check valve, it should be cleaned regularly, otherwise it will make the check valve open and lose its effect, and it is best to replace the flue check valve once every two years

how to clean the smoke exhaust pipe in the kitchen

1. The installation and cleaning personnel first remove the top and bottom sections of the pipe, 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 stain in the vertical flue from top to bottom. This method is dangerous, technical, expensive and effective. Because the vertical flue generally has less oil accumulation, it can be cleaned once a year

2. This method has high labor intensity, that is, the manual entry method. For parallel flues larger than 40 cm square, they can be manually drilled in for cleaning. Pay attention to strengthen ventilation and equip low-voltage (36V) lighting power supply

3. This method is used when manual access is impossible, that is, the disassembly method. When the flue is less than 40 cm square. According to the actual situation on site, the installation and cleaning personnel disassemble a section of flue at regular intervals and extend it to both sides for cleaning. This method has good effect, great difficulty and high cost

4. The installation and cleaning personnel use a special non sparking drilling tool to drill one or more holes in the pipeline, that is, the tapping method. This method is used for the flue that cannot be accessed manually and is difficult to disassemble. The size, spacing and number of openings shall be determined according to the site conditions. After the oil stain is cleaned, the pipeline shall be sealed and restored

5. The flue with short cleaning cycle is cleaned by this method, that is, machine and equipment cleaning method, which has less oil pollution. Spray cleaning agent in the pipeline first to soften the oil stain, and then use an electric flexible shaft brush with a length of 30 meters to clean the oil stain. This method is used for 30 cm square vertical flue, concealed small flue that cannot be accessed manually and is inconvenient to be disassembled. This is not easy to clean and easy to accumulate oil, so the cleaning cycle should be shortened
