Abstract

The invention discloses energy-saving and environment-friendly flue gas desulfurization equipment in the technical field of flue gas desulfurization, which comprises a self-scraping communicating pipe communicated between an exhaust port of an absorption tower and an air inlet of a bag-type dust collector, and a scraper part driven by hot air pressure and a flow stirring part driven by the scraper part are arranged in the self-scraping communicating pipe. The scraper part comprises two wall scraping plates which are symmetrically arranged and can be turned and closed, the outer side walls of the wall scraping plates are in sliding connection with the inner wall of the ventilation channel of the self-scraping communicating pipe, and the two wall scraping plates are arranged on one side of the exhaust port of the absorption tower and cover the ventilation channel in the self-scraping communicating pipe; the flow stirring part comprises a suction fan blade and a reverse blowing fan blade which are rotationally mounted at the axial lead position of the ventilation channel; flue gas in the ventilation channel integrally passes in a pulse airflow mode, self-cleaning of the interior of the ventilation channel is achieved in the airflow passing process, the desulfurization efficiency in the absorption tower and the dust removal efficiency in the bag-type dust remover are reversely improved, heat energy of the flue gas is utilized, and more energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to energy-saving and environment-friendly flue gas desulfurization equipment. Background technique [0002] The circulating reflux semi-dry desulfurization process is an advanced flue gas semi-dry desulfurization process based on the principle of circulating fluidized bed technology. The process uses dry slaked lime powder as the absorbent, and sprays process atomized water into the flue gas to humidify and activate the acidic substances in the flue gas, and recirculates the dry powder absorbent for many times, and in the absorption tower with The flue gas pollutants are strongly exposed to chemical reactions, prolonging the contact time between the absorbent and the flue gas to achieve the purpose of efficient desulfurization. The desulfurization system is mainly composed of a flue gas system, an absorption tower system, an absorbent preparation system, a dust remo...
