Dedusting and desulfurizing device

Abstract

The invention discloses a dedusting and desulfurizing device which comprises a chimney and a dust collection box, wherein the chimney and the dust collection box are connected sequentially from top tobottom, an opening is formed in the upper part of the chimney, a plurality of filtering screen barrels are fixed at the bottom of the chimney, the lower parts of the filtering screen barrels are connected with the dust collection box, sliding pistons are further arranged in the filtering screen barrels in a sliding manner and connected with a transmission mechanism by fulcrum bars, a desulfurizing plate which is located above the filtering screen barrels and arranged in an inclined manner is further fixed in the chimney, a discharge pipe and a feed pipe are further fixed on the two opposite sides in the chimney respectively, a discharge port which is located above the desulfurizing plate is formed in the surface, in contact with the chimney, in the discharge pipe, a feed part which is located above the desulfurizing plate is formed in the surface, in contact with the chimney, in the feed pipe, and electromagnetic door mechanisms are arranged at the discharge port and the feed port; the problem that the smoke exhausted from a village domestic chimney cannot be effectively filtered so as to reduce the contents of the particles and sulfur dioxide in the smoke is solved.

Description

technical field [0001] The invention relates to flue gas treatment equipment, in particular to a dust removal and desulfurization device. Background technique [0002] my country's annual consumption of scattered coal is about 700-800 million tons, accounting for 20% of the total coal consumption, which is mainly used for small heating boilers. Taking Hebei Province as an example, the total amount of air pollutant emissions from household coal consumption of 50 million tons is approximately equal to that of the production of 1 billion tons of coal-fired electricity. Because of direct combustion and direct exhaust, low chimney height, SO in Shijiazhuang County 2 And PM2.5 concentration values ​​are even higher than urban areas. Nowadays, the burning of scattered coal has become an important cause of smog in autumn and winter, and the treatment of the problem of "non-point source" smoke exhaust in rural areas is imminent. With the improvement of rural living standards, coal...
