Abstract

An integrated dust removal and desulfurization tower is provided. The vertical lower part of the absorption tower body is a cyclone dust collector, and the upper end is equipped with double desulfurization and dust reduction devices; the double desulfurization and dust reduction devices include intestinal flue gas drainage, desulfurization channels and spray racks Among them, the lower end of the intestinal flue gas drainage and desulfurization channel is connected to the cyclone dust collector, the upper gas outlet port extends into the absorption tower body, and the horizontal section is provided with a vertical flue gas recirculation and dust reduction channel connected to the flue dust inlet; above the gas outlet port Equipped with an umbrella-shaped flue gas diffuser and a nozzle; connected to the nozzle, a funnel-shaped flue gas dispersion grid is installed to disperse the air flow in the absorption tower cylinder and to recover the desulfurizer sprayed by the spray rack. The dust reduction and desulfurization vertical integration design of the present invention occupies a small space, has a compact structure, consumes less desulfurization liquid, has high desulfurization efficiency, and has superior comprehensive performance.

Description

Technical field[0001]The invention belongs to the technical field of a desulfurization tower for separating and purifying flue gas with liquid, and specifically relates to an integrated dust removal and desulfurization tower.Background technique[0002]At present, with economic development, social progress and people’s awareness of environmental protection, the removal of SO2 from industrial flue gas has received increasing attention. In recent years, the state has strengthened the monitoring and management of the atmospheric environment, formulated relevant policies and smoke emission standards, and strictly regulated the SO2 content in the smoke emission standards. In this situation, various desulfurization equipment came into being. Under the existing technology, the main problems of the widely used industrial kilns and other waste gas and dust purification treatment environmental protection equipment are: 1. The dust removal system and the desulfurization system adopt the external...
