The wall of the kitchen smoke exhaust hood installation should have sufficient strength in terms of structure and materials. The external wall openings of smoke exhaust pipes and air ducts can be made by building prefabricated concrete blocks with holes or embedding steel pipes with holes. The installation method for insulation walls (preferably using hollow bricks) is the same as for normal walls. If the walls are not strong enough, they need to be reinforced with wooden boards or other materials.
The smoke pipe installed on the kitchen exhaust hood directly passes through the exterior wall to the outside, and components should be installed at the outdoor exhaust outlet to prevent environmental pollution and avoid wind. The section of the vertical flue of the kitchen smoke exhaust hood of the Aileri Hotel, which is connected by a shared vertical flue, should be calculated and determined based on the amount of exhaust it bears.
The smoothness of smoke exhaust directly affects the normal operation of the kitchen, while oil fume purification is only a mandatory function of purifying air in the kitchen smoke exhaust system. The reasonable matching of the smoke exhaust system and purifier is the key to ensuring the purification efficiency of the Ailerui oil fume purifier, and it is also a problem that designers of oil fume purifiers tend to overlook. If the smoke exhaust system design is not reasonable and causes poor smoke exhaust in the entire kitchen, Jinan kitchen smoke exhaust will not be able to install an oil fume purifier, even if an oil fume purifier is installed, it will not work properly.
Due to the lack of calculation basis for matching the oil fume exhaust and collection system with the purifier in GB18483-2001, in practice, the pipeline of the European style smoke machine is generally in the middle position, while the exhaust pipe outlet of the sergeant smoke machine is on one side of the smoke machine. These situations affect the location of reserved openings.
Even if an oil fume purifier is installed for kitchen smoke exhaust, it cannot function properly. Due to the lack of calculation basis for matching the oil fume exhaust and collection system with the purifier in, there is a lack of reliable and practical calculation methods for the design of the oil fume exhaust and purification system in practice. Mastering the characteristics of each part of the smoke exhaust system and its impact on the overall smoke exhaust of the kitchen is a prerequisite for selecting and installing a range hood purifier, and is of great significance for ensuring the normal operation of the range hood purifier.
