DEVICE AND METHOD FOR TREATING AND PRODUCING FRESH AIR

摘要

The invention concerns a device for treating and producing fresh air in an air-delivery system disposed in a bed (22, 24, 26) of solids particles, the device comprising an air-collector shaft (1) and connected thereto an air-extraction pipe (5). The device is characterized in that a plurality of elongate hollow elements (3), each comprising a plurality of air-inlet openings, lead into the air-collector shaft (1) which is connected for flow to the fresh air in the bed (22, 24, 26) of solids particles only by the hollow elements (3). The method of treating and producing fresh air comprises the following steps in which the fresh air flows: through the surface of the earth with a surface structure having a high specific surface area; through a bed of solids particles; through air-inlet openings into hollow elements which lead into an air-collector shaft; and into the air-collector shaft.
