ABSTRACT:
The device is positioned in a stack arranged above a location where coke quenching is performed. The coke quenching, which takes place below the stack, evolves steam and gases containing solid coke particles or dust, and which must be prevented from passing into the outside atmosphere. The steam and gases flow upwardly through the stack and the device separates the solid coke particles and dust from the steam and gases. The device comprises a support beam carrying a plurality of shutter-like baffles, of plastic material, and liquid spray elements, and which is variable in length and positioned either obliquely or horizontally across the upper portion of the stack. In between successive coke quenching operations, the liquid spray elements are activated to flush the trapped solid coke particles and dust from the shutter-like baffles. The adjustable length of the device provides for the device to be positioned to extend across the stack at varying angles, or even horizontally. The device may be pivoted at either end of the stack so that it may be swung about the pivot to vary the angle of inclination of the device in the stack, and the adjustable length of the device accommodates the various oblique positions or the horizontal position. The support beam advantageously is supported by a diagonal brace extending from one wall of the stack to the support beam.
