Central emission suction device from one or more emission sites

A modular central emission suction device (100) for transporting smoke or fumes from one or more emission sites (210a, 210b, 210c, 210d, 210e), intended to be arranged on the outside of a building (220), the emission suction device comprising

• a main smoke duct (110) configured to be arranged on the outside of the building, the main smoke duct comprising an outlet (112) configured to be arranged on the building,
• one or more connection ducts (120a, 120b, 120c, 120d, 120e) configured to be connected to the main smoke duct, each connection duct comprising an inlet (122a, 122b, 122c, 122d, 122e) configured to be arranged at each emission site of the one or more emission sites, and wherein the inlet is configured to receive smoke or fumes from the emission site,
• one or more fan units (130) configured to be arranged at the building and to be connected to the main smoke duct, said fan units being configured to create a main air flow (F1) in the main smoke duct with a flow direction towards the outlet, and
• wherein the main air flow in the main smoke duct creates a connection air flow (F2a, F2b, F2c, F2d, F2e) at each inlet such that smoke and fumes are transported away from said emission sites to the outlet, and
• wherein the main smoke duct, the one or more connection ducts and the one or more fan units are mountable in such a way that the emission suction device can be adapted to the configuration of the building.
