Problems solved by technology

[0003] Most of the existing desulfurization, denitrification and dust removal devices use spraying to remove dust. During the dust removal process, the contact between the exhaust gas and the desulfurization and denitrification liquid is not sufficient, the desulfurization and denitrification effect is poor, and the dust removal efficiency is relatively low.

Abstract

The invention discloses a desulfurization, denitrification and dust removal device. The device comprises a reaction box, a desulfurization and denitrification cylinder and a dust removal tower, a hollow rotating shaft is rotatably mounted in the desulfurization and denitrification cylinder, a fixed pipe is mounted on the hollow rotating shaft, an air hole is formed in the fixed pipe, a fixed sleeve is mounted at the bottom of the desulfurization and denitrification cylinder, a first connecting pipe is communicated between the fixed sleeve and a reaction box, a through hole is formed in the hollow rotating shaft in the fixed sleeve, a first-stage filter plate, a second-stage filter plate and a drying plate are respectively arranged in the dust removal tower from bottom to top, a valve is installed at the bottom of the desulfurization and denitrification cylinder, a collecting box is movably installed below the valve, and a scraper is installed on the hollow rotating shaft. According tothe desulfurization, denitrification and dust removal device, waste gas generated in the reaction box is introduced into the hollow rotating shaft to form spirally ascending bubbles, so that the contact area of the waste gas and desulfurization and denitrification liquid is increased, meanwhile, the desulfurization and denitrification liquid is disturbed, so that the desulfurization and denitrification effect is improved, and a detachable collecting box is convenient for regular cleaning of impurities.

Description

technical field [0001] The invention relates to the technical field of waste gas purification and treatment, in particular to a desulfurization, denitrification and dust removal device. Background technique [0002] Industries and fields such as energy, chemical industry, metallurgy, and electronics all involve the combustion of fuels such as coal, oil, and natural gas. smoke and dust; smoke and dust will reduce the visibility of the atmosphere, weaken the photosynthesis of plants, affect the lung function of humans and animals and cause related diseases; sulfides in the atmosphere will form acid rain, corrode buildings, affect plant growth and endanger human health; nitrogen Oxides in the atmosphere will not only form acid rain, but also form photochemical smog in the atmosphere, and will deplete ozone and even destroy the ozone layer, which is very important for desulfurization, denitrification and dust removal of industrial waste gas. [0003] Most of the existing desulf...
