The utility model relates to the technical field of building ventilation, and discloses a
green building ventilation structure which is characterized in that a control device is fixedly mounted on the right side of a
settling box, an air inlet is fixedly mounted on the top surface of the
settling box, a rain shelter is fixedly mounted on the top surface of the air inlet, a water inlet
pipe is fixedly mounted on the side surface of the
settling box, and a water outlet
pipe is fixedly mounted on the water inlet
pipe. Spraying systems are fixedly installed on the left side and the right side of the interior of the settling box, an
activated carbon box is fixedly installed on the rear side of the settling box, and a motor box is fixedly installed on the bottom face of the
activated carbon box. According to the ventilation structure of the
green building, the fan is started through the control device to start to work, after air is sucked into the settling box, the spraying device adsorbs and deposits large-particle dust into the water collecting area through water mist sprayed out of the spray head, and the dust is left in strands, enters the water outlet and then is discharged into a sewer through the drainage pipeline; meanwhile, the fan acts to suck air containing water mist into the
activated carbon box, and activated carbon not only can filter tiny dust in the air, but also can adjust the
humidity in the air.
