MULTI-TOWER APPARATUS FOR TREATING GAS AND DUST HARMFUL TO ENVIRONMENT GENERATED FROM VARIOUS PROCESSES BY MULTISTAGE TREATMENT SYSTEMS, AND METHOD FOR TREATING GAS AND DUST BY THE SAME BEING CAPABLE OF INSTALLING ON SMALL AREA

摘要

PURPOSE: To provide a multi-tower apparatus which completely treats gas and dust harmful to environment by multistage treatment systems installed inside the apparatus to prevent environmental pollution, and which is constructed in a compact structure such that the apparatus is easily installed on a small area and maximizes gas treatment efficiency, and a method for treating the gas and dust by the multi-tower apparatus. CONSTITUTION: The multi-tower apparatus(10) consisted of multistage treatment systems for treating gas and dust harmful to environment generated from various processes comprises an outer cylinder(12); an inner cylinder(13) extended to a lower part(16) of the outer cylinder in the outer cylinder with being spaced apart from an upper part of the outer cylinder and left and right sides of the outer cylinder in a certain gap; a through hole installed on a lower part of the inner cylinder such that the inner cylinder and the outer cylinder are communicated with each other through the through hole; a gas injection port(11) formed on an upper part of the outer cylinder; a plural steam nozzles(20) installed on an upper inner part of the outer cylinder with being distanced from each other in a certain gap; a plural cleaning solution nozzles(14) installed under the steam nozzles with being distanced from each other in a certain gap; a multi-venturi(30) installed between the outer cylinder and the inner cylinder in such a way that the plural cleaning solution nozzles are installed under the multi-venturi; a packing part(40) installed in certain dimensions under the multi-venturi; and a bubbling part(50) and cleaning solution nozzle(14) repeatedly installed in an upper inner part of the inner cylinder corresponding to a position where the packing part is installed.
