INSTALLATION FOR DUST-FREE ISSUE OF COKE FROM COKE BATTERY FURNACES Russian patent published in 2022 - IPC C10B33/00 

FIELD: coke industry.

SUBSTANCE: invention relates to the coke industry, in particular to devices for removal of dust-gas products formed in coke issue from coke furnaces to a moving coke-drying car, in particular to an installation for dust-free coke issue from coke battery furnaces. The installation contains a door-removable machine with a dust-suction hood, a gas removal collector, and a smoke exhauster, the dust-suction hood equipped with a casing installed inside it and closed from above, placed with a slot gap relatively to hood walls, while the slot gap is made with a size providing coming of a dust-suction mixture at a speed from 40 to 60 m/s and a volume, which is 1.1-1.21 of a volume of primary sucked air. Moreover, the hood is made of an asymmetrical shape in a lower part within a length of the coke-drying car along the course of movement of the car, in a transverse part, at an end of the hood, an additional slot channel is made with its removal to a central upper part of the hood. At the same time, a fan is installed on the additional slot channel, on an upper part of a gas duct, for creation of thrust in the lower part of the hood, in the upper part of the casing, left and right from sides of the hood, a row of vertical longitudinal windows is made, slot gates are made with the same windows. Moreover, a width of windows is equal to jumpers between them, so that, when moving horizontally left or right, slot windows are opened or closed.

EFFECT: increase in the efficiency of selection of dust-gas emissions into the atmosphere and reduction in metal consumption of a hood.
