Abstract: The present application provides a wet scrubber system for treating a flow of flue gases with dioxins therein with a flow of a fluid. The wet scrubber system may include a column member, a packed bed positioned within the column member, and an activated carbon filter bed system in communication with the column member such that at least a portion of the flow of the fluid passes through the activated carbon filter bed system to remove the dioxins therein before being recirculated back to the column member.

Abstract: The guiding device has foldable legs that are connected to an upper connector and a lower connector. The legs are foldable along hinges. The hinges to the upper and lower connectors rotatably connect the ends of the legs. The guiding device may be moved from an expanded position to a collapsed position and moves along a straight line L. The guiding device may be used to hold drilling machines and other tools.
