Active carbon adsorption tower

Abstract

The invention relates to an active carbon adsorption tower. The adsorption tower comprises a tower body and filter assemblies; the bottom of the tower body is mounted on the ground through a bracket,the bottom of the tower body is provided with a slag discharge port, the lower end of the side wall of the tower body is provided with a flue gas inlet, and the upper end of the side wall of the towerbody is provided with a flue gas outlet; each filter assembly comprises an inner-layer filter element and an outer-layer filter cylinder which are separately mounted in the tower body, wherein the inner-layer filter element is of a vertically arranged cylinder structure with an open lower end, and the outer-layer filter cylinder is a cylinder body with an open lower end and sleeves the inner-layer filter element; the side wall of each outer-layer filter cylinder is of a double-layer structure, a filling filter cavity with an open lower end is formed between the side walls of each inner layerand the corresponding outer layer, the upper end of each filling filter cavity is provided with a feeding port, and a switch assembly for opening or closing the corresponding filling filter cavity isarranged at each open lower end; the top of the tower body is provided with holes through which the filter assemblies penetrate. The adsorption tower has the advantages that the structural design is simple and reasonable, the problems can be effectively solved that the adsorption burden of active carbon layers in existing active carbon adsorption towers is large and it is difficult to feed and discharge fillers, and the requirement of flue gas treatment can be met.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to an activated carbon adsorption tower. Background technique [0002] Exhaust gas purification mainly refers to the work of treating industrial waste gas such as flue gas and dust, odorous gas, and toxic and harmful gases generated in industrial places. [0003] Common waste gas purification includes factory smoke and dust waste gas purification, organic waste gas purification, acid-base waste gas purification, chemical waste gas purification, etc. The direct discharge of waste gas will cause serious environmental pollution, and the adsorption tower is one of the most commonly used equipment in waste gas purification, and its role is self-evident, but the existing adsorption towers have problems such as large adsorption burden on the activated carbon layer and difficulties in feeding and discharging materials. Can not meet the requirements of use. Contents of the inve...
