The smoke exhaust system of the kitchen is mainly composed of smoke collecting hood, smoke exhaust pipe, oil fume purifier, smoke exhaust fan (including muffler) and integral air supplement device of the kitchen, as shown in the figure below.
The type and operation mode of oil fume purifier can be selected according to the actual situation. Before the installation of the fume purifier, the actual operation parameters of each part of the exhaust system, including the operation resistance and exhaust air volume, should be calculated. If it is a new project, the influence of installation of fume purifier on the exhaust system should be fully considered in the design; If it is a renovation project, the exhaust system needs to be checked again when installing the oil fume purifier. If necessary, the smoke collecting hood, smoke exhaust pipe and the overall air supplement device of the kitchen should be reformed and the smoke exhaust fan should be replaced.
