Abstract

A multi-stage cleanser for removing sulfur and dust from fume is composed of fume inlet pipe, diffusing pipe, reduced pipe, reaction trunk, fume outlet pipe, liquid inlet tube and liquid outlet tube.Said reaction trunk has at least 3 reaction branch pipes, which has a water barrier at its end to form a liquid tank. The number of said liquid tanks must be more enough to ensure uniform and fast gas-liquid reaction. Its advantages are simple structure and high effect.

Description

Technical field [0001] The invention relates to an industrial gas purification device, in particular to a multi-stage flue gas desulfurization and dust removal purification device. Background technique [0002] The exhaust gas of boilers, kilns, and industrial furnaces that use coal or oil as fuel contains a lot of smoke and toxic gases (mainly sulfur dioxide). At present, the equipment used in industry to deal with the above-mentioned flue gas includes wet dust removal series and electrostatic dust removal series. Among them, the advantage of the wet dust removal series is that it can desulfurize at the same time as the dust removal, but the disadvantage is that it is only suitable for the conditions of small amount of flue gas (small boiler) or less dust in the flue gas; while the electrostatic dust removal series has a good dust removal effect. But not desulfurization. [0003] At present, most of the wet dust removal series are wet swirl plate technology and spray tech...
