Embodiment Construction

[0041] The dust removal, desulfurization and denitrification integrated tower of the present invention includes a denitrification layer, a desulfurization layer and a steam-water separation layer in sequence from the bottom of the tower, and the positions of the denitrification layer and the desulfurization layer can also be exchanged, that is, from the bottom of the tower upwards Including the desulfurization layer, denitrification layer and steam-water separation layer, but the most preferred structure is that the denitrification layer is on the bottom and the desulfurization layer is on the top, because the product produced by the denitration layer can be mixed with the ash emulsion in the desulfurization layer The reaction is carried out to prevent the release of substances such as nitric acid from the chimney into the atmosphere. At the bottom of the dust removal, desulfurization and denitrification integrated tower, a water film dust removal layer can be set for prelimina...

Abstract

The invention provides a dust removal, desulfurization and denitrification integrated tower which sequentially comprises a water film dust removing layer, a denitration layer, a desulfuration layer and a steam-water separation layer from bottom to top; the positions of the denitration layer and the desulfuration layer can be exchanged. The invention also provides a dust removal, desulfurization and denitrification integrated system which comprises an air inlet device, a purification device and a recovery device, wherein the air inlet device is connected with the purification device; the purification device is connected with the recovery device. After the dust removal, desulfurization and denitrification integrated tower and the dust removal, desulfurization and denitrification integrated system are used for treating waste material, the pollution is reduced, the reaction raw material is saved, the device is easy to clean, the service life is prolonged, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the field of tail gas treatment and purification, and in particular relates to a dust removal, desulfurization and denitrification integrated tower and a dust removal, desulfurization and denitrification integrated system. Background technique [0002] The exhaust gas after coal combustion in traditional coal-fired power plants is directly discharged into the atmosphere after dust removal, desulfurization and denitrification approach or even meets the emission standards, and some of them have not yet reached the standards. The exhaust gas contains sulfur dioxide, nitrogen dioxide, Harmful gases such as nitric oxide and fine solid impurity dust such as fly ash with light specific gravity and small particles. After 75 tons of coal is burned in the boiler, the amount of sulfur dioxide discharged can reach 10 tons per day. These sulfur dioxide, nitrogen oxides and fine particles are the main killers of smog, which will greatly aff...
