Integrated type dust-removal desulfurizing tower

Abstract

The invention provides an integrated type dust-removal desulfurizing tower. A vertical lower part in an absorbing tower barrel body is provided with a cyclone dust collector; the upper end of the absorbing tower barrel body is provided with a dual-desulfurizing and dust-collecting device; the dual-desulfurizing and dust-collecting device comprises an intestine-shaped smoke gas guide and desulfurizing channel and a spraying frame; the lower end of the intestine-shaped smoke gas guide and desulfurizing channel is communicated with the cyclone dust collector to ventilate; the upper gas outlet port extends into the absorbing tower barrel body, and the horizontal section is provided with a vertical smoke gas recirculating dust-collecting channel which is communicated with a soot inlet; an umbrella-shaped smoke gas diffusing cover and a spray head are arranged above the gas outlet port; and a funnel-shaped smoke gas dispersing grid which is used for dispersing gas flow in the adsorbing towerbarrel body and recycling a desulfurizing agent sprayed by the spraying frame is mounted on the spray head in a communication mode. The integrated type dust-removal desulfurizing tower adopts a dust-collecting and desulfurizing vertical integrated design, is small in floor space, is compact in structure, is less in desulfurizing liquid, is high in desulfurizing efficiency, and is excellent in 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 in particular relates to an integrated dust removal and desulfurization tower. Background technique [0002] At present, with the development of the economy, the progress of society and the enhancement of people's awareness of environmental protection, the removal of SO2 from industrial flue gas has been paid more and more attention. In recent years, the state has strengthened the monitoring and governance of the atmospheric environment, formulated relevant policies and smoke emission standards, and made strict regulations on 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 environmental protection equipment for waste gas and dust purification treatment such as industrial kilns are as follows: 1...
