Composition of kitchen smoke exhaust system.
The smoke exhaust system of the kitchen is mainly composed of a smoke collecting hood, smoke exhaust pipes, oil fume purifiers, smoke exhaust fans (including *) and an integral air make-up device of the kitchen.
The type and operation mode of lampblack purifier can be selected according to the actual situation. Before installing the lampblack purifier, the actual operating parameters of each part of the smoke exhaust system, including operating resistance and exhaust air volume, shall be checked.
If it is a new project, the impact on the exhaust system after installing the lampblack purifier shall be fully considered in the design; If it is a reconstruction project, the exhaust system needs to be recalculated when installing the lampblack purifier. If necessary, the smoke collecting hood, smoke exhaust pipe and kitchen integral air supplement device should be reconstructed and the smoke exhaust fan should be replaced.
2. Determination of kitchen lampblack exhaust volume.

In order to ensure the purification effect, the smoke exhaust air volume is required to be calculated in strict accordance with the suction air speed of the exhaust hood in the actual design, and the suction air speed at the hood opening is generally not less than 0.5m/s.
