An energy-saving and environment-friendly flue gas filtration system

Abstract

The invention discloses an energy-saving and environment-friendly type flue gas filtering system. The energy-saving and environment-friendly type flue gas filtering system comprises a dust filter, a gas absorption tank, an adsorption pot and an exhausting pipe; dust solid particles in flue gas are removed through the dust filter; the gas absorption tank is used for absorbing and removing acidic gas including carbon dioxide, sulfur dioxide and the like in the flue gas; an adsorbent in the adsorption pot is used for adsorbing and removing carbon monoxide in the flue gas; preparation of the adsorbent in the adsorption pot comprises the following steps: firstly, enabling ruthenium trichloride and sodium periodate to react in an acidic environment, and oxidizing ruthenium trichloride into a high-valence ruthenium compound; then loading the high-valence ruthenium compound into modified chlorite and sufficiently dispersing the high-valence ruthenium compound in the surface and pore channels of the modified chlorite, wherein high-valence ruthenium can be complexed with 4 carbon monoxide at the same time, and the adsorption amount of the chlorite adsorbent on carbon monoxide is 130ml / g or above and is much higher than the loading amount of an existing transition metal loaded adsorbent on the carbon monoxide, so that the adsorbent has relatively high industrial production value.

Description

Technical field [0001] The invention belongs to the technical field of dust removal, and specifically relates to an energy-saving and environment-friendly flue gas filtering system. Background technique [0002] In industrial production, a large amount of dust-containing flue gas is produced during the combustion of fuel. Dust flue gas is a mixture of gas and soot and is the main cause of air pollution in residential areas. The composition of the flue gas is very complicated. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, and carbon dioxide. If it is directly discharged into the air, it will cause environmental pollution. One of the existing common treatment methods is to set a filter pool outside the boiler, connect the boiler's flue pipe to the pool, and send the dust-containing flue gas into the filter pool so that the dust is filtered by the water in the pool. Then the filtered flue gas is discharged into the air. Another treatment method i...
