Abstract

The invention discloses environmental-friendly denitration dust collection equipment for a kiln gas and relates to the technical field of kiln waste gases. The environmental-friendly denitration dustcollection equipment comprises SCR (Selective Catalytic Reduction) denitration equipment, wherein the gas inlet of the SCR denitration equipment is communicated with the inner cavity of a treatment chamber through a gas guide tube; the treatment chamber is positioned above the left side of the SCR denitration equipment; a water pump is arranged on the left side of the denitration equipment; the water outlet of the water pump is connected and communicated with the bottom end of a water conveying tube; the top end of the water conveying tube is inserted into the treatment chamber; the top of thetreatment chamber is communicated with a gas tube. By adopting the environmental-friendly denitration dust collection equipment for the kiln gas, the contact area of a heated bag with a sputtered water body is increased while the surface area of the heated bag is increased, the contact area with the gas is further increased, then the treatment volume of alkali oxides in the gas is increased, andalkali substances dropped into a curved bar frame from the surface of an inclined rod after reactions are discharged out from a water leaking hole downwards.

Description

Technical field [0001] The invention relates to the technical field of kiln waste gas, in particular to an environmentally friendly denitrification and dust removal equipment for kiln flue gas. Background technique [0002] The flue gas emitted by industrial kilns ranks high in the total industrial nitrogen oxide emissions. In order to achieve a large amount of flue gas emissions to meet the emission standards, denitrification measures play a vital role in the flue gas treatment process. The flue gas treatment stage can be It is divided into fuel pre-treatment, fuel process control and later flue gas denitration. The later flue gas denitration methods mainly include selective non-catalytic reduction reaction (SNCR) technology, selective catalytic reduction reaction (SCR) technology and combined denitration technology (SNCR+ SCR), before using SCR equipment, the viscous dust in the flue gas needs to be effectively treated, which can reduce the damage of alkaline oxides to the cata...
