Entire smoke exposure device

摘要

An apparatus includes a smoke emitting section (5) which emits smoke containing particulate matter, a dilution means (6) for diluting the smoke emitted by the smoke emitting section (5), an clean air unit (3) which supplies clean air to the dilution means (6), at least one chamber (10) which incorporates a cell-adhered surface and into which the smoke diluted by the dilution means (6) is introduced, and an exhaust means (82, 84) for exhausting the smoke from the chamber (10) and the dilution means (6). A smoke flow in the chamber (10) is shut off to make the smoke settle down in the chamber (10) and expose the cell-adhered surface to the smoke. <IMAGE>
