How to design smoke exhaust pipes is actually the most important thing in the kitchen decoration of catering industry, not only because the kitchen is the source of daily food demand, but also because the kitchen is intertwined with water and electricity pipes and sewers. If all these unreasonable designs in the past will bring irreparable losses to the future, even the loss of life and property, improper handling will also affect long-term health problems. So, how to design smoke exhaust to match the use of kitchen fume purifier? Insufficient smoke exhaust from flue is not only a problem of range hood, but also a problem of flue. Because kitchen problems are often exposed after long-term use, the future transformation must be positive. Once this problem occurs in the family, it can only be solved temporarily by radical methods. In order to avoid this situation, we must make full preparations in the early stage of decoration.

Usually, the flue in residential buildings is divided into two parts, the main flue runs through the whole building, and the auxiliary flue is independent of each residence. Household lampblack first enters the auxiliary flue, then enters the main flue through the partition hole, and finally is discharged from the main flue to ensure the independence of each household lampblack. The main flue, that is, a pair of flues, can directly obtain architectural drawings or professional property solutions.

Pipes cannot be placed at will. Some commercial kitchens are decorated with aesthetic problems in mind. The stove is far from the smoke outlet. If the flue is too long, the soot will not be removed in time, and they will gradually adsorb on the inner wall of the pipeline. After long-term use, the smoke exhaust capacity will become worse and worse, and even the situation of filling oil fume will appear. Therefore, the position of flue is very important. In the early stage of decoration, the installation position of flue machine should be determined according to the position of flue entrance, and the distance between flue entrance and flue entrance should not exceed 1. 5 meters. In order to prevent smoke from the flue, a check valve must also be installed. After that, it needs to be cleaned regularly, otherwise the check valve will open and lose its function. [Picture] Some households can directly discharge oil fume from the wall, and the pipes are connected with the wall. This is no problem, but it should be noted that the construction must obtain the consent of the property; The hole should not be too small to prevent the pipe from heating to the window and the glass from bursting when heated; The outlet of the pipeline must be downward to prevent rainwater from flowing in and keep out the wind.

In addition, it should be noted that pipes and walls should be carefully checked for cracks. Before tiling, the net must be hung to check the adhesion between the wall and the wall brick. Because the pipe wall of the flue is very thin, we must be very careful in construction to avoid damaging the pipe. Any tiny crack may make the flue gas flow back to the kitchen.
