FIELD: measuring equipment.
SUBSTANCE: air pollution control device comprises a leeward wall adjacent to a contaminated area and a windward wall located between the leeward wall and the contaminated area. The leeward wall and the windward wall are spaced apart from each other to form a passageway for the airflow between them. The windward wall goes up to the height of the first wall. The leeward wall includes an upper section extending above the first wall height. The upper section is designed to direct the air flow downwardly through the air flow passageway in the direction of at least one opening located below the first height of the wall for removing air flow from the air flow passageway.
EFFECT: air pollution reduction.
