Industrial kiln waste gas desulfurization, denitrification and dust removal integrated equipment

Abstract

The invention discloses industrial kiln waste gas desulfurization, denitrification and dust removal integrated equipment in the technical field of industrial kiln waste gas desulfurization, denitrification and dust removal integrated equipment. The industrial kiln waste gas desulfurization, denitrification and dust removal integrated equipment comprises a pretreatment barrel and a desulfurization, denitrification and dust removal reaction box. According to the invention, when industrial kiln waste gas is treated, stirring blades are used for driving the waste gas to rotate so as to centrifugally separating the waste gas containing large particles and the waste gas containing small particles, and the large-particle waste gas is filtered by a smoke dust filtering membrane when moving towards the outer side and passing through the smoke dust filtering membrane to adsorb large and many smoke dust particles so as to pretreat the large-particle smoke dust in the smoke dust, so that the smoke dust in the waste gas entering the treatment liquid is relatively rarefied, the large particles are reduced, excessive treatment liquid does not need to be consumed, the cost is reduced, local consumption is relieved, and the problem that the smoke dust cannot be fully treated due to insufficient treatment liquid caused by rapid consumption of local treatment liquid is avoided.

Description

technical field [0001] The invention relates to the technical field of integrated equipment for desulfurization, denitrification and dust removal of waste gas from industrial kilns, in particular to an integrated equipment for desulfurization, denitrification and dust removal of waste gas from industrial kilns. Background technique [0002] With the progress of the society and the development of the economy, there are more and more various power station boilers, industrial kilns, electric arc furnaces, especially coal-fired industrial boilers. Correspondingly, the burden on the environment has increased and the air pollution has become increasingly serious. Various environmental protection laws and regulations have also been gradually promulgated to meet the increasingly harsh environmental protection needs; coal is the main energy source in my country, and the accompanying pollution problems of sulfur dioxide and acid rain will become more prominent. Sulfur, chlorine, and nit...

Problems solved by technology

[0006] The object of the present invention is to provide an integrated equipment for desulfurization, denitrification and dust removal of industrial kiln waste gas, to solve the problem in the prior art when desulfurization, denitrification and dust removal of industrial kiln waste gas is carried out in the above background technology. Contains a lot of smoke and dust. When using dust removal equipment to remove dust from the exhaust gas, a large amount of smoke and dust in the industrial kiln exhaust gas will react with the treatment liquid, which will quickly consume the treatment liquid. Consumption, which increases the processing cost, on the other hand, it will cause the local processing liquid in the local space to be consumed too quickly, resulting in a shortage of local processing liquid and affecting the processing effect
