Abstract:
A hood adapted to remove contaminants from incoming airflow comprising a housing member having top, front, back and side walls, and defining a lower liquid sump, and an upper exhaust opening in the top wall, an inlet opening defined in the front wall of the housing member the front wall is inclined inwardly and downwardly, a partition extends between the side walls downwardly from the front wall and has a free end defining an air passage with the back wall leading to a large volume upper portion of the housing, a screen having openings therein extends between the side walls and downwardly from the free end of the partition into the sump, the partition has a dam on the free end thereof having a horizontal upper edge, liquid will overflow the dam on the partition and move across the openings in the screen to the sump, whereby air passing into the inlet opening passes through the liquid moving across the screen and then through the liquid moving across the screen and then through an agglomeration of liquid in the upper housing, a removable liquid header is mounted to an extends across the top wall and has a plurality of spaced apart nozzles extending through openings in the top wall into the housing member above the front wall liquid introduced into the header exits through the nozzles into the upper part of the housing and is agglomerated as the airflow enters the upper part of the housing.
