摘要

FIELD: heating. ^ SUBSTANCE: present invention pertains to types of exhaust hoods over processing assemblies. The device has an exhaust hood with vertical walls, a suck in opening and a gas outlet nozzle. Along the perimeter of the exhaust hood, there are extra vertical walls and overheard surfaces, which form gas storage containers. The extra vertical walls are fitted on the outer side of the exhaust hood at a distance 0.25-0.60 of the corresponding size of the width or length of the suck in opening of the exhaust hood. ^ EFFECT: increased efficiency of trapping dust and gas emissions. ^ 2 dwg
