Embodiment 1

[0035] The first embodiment discloses a desulfurization and dust removal absorption tower provided with a porous homogenizer, comprising: a tower body, the tower body has a flue gas inlet and a flue gas outlet, the flue gas inlet is located at the lower part of the tower body, and the flue gas outlet is located on the tower body At least one sprayer, arranged in the tower body, between the flue gas inlet and the flue gas outlet of the tower body, for spraying the slurry; and at least one porous homogenizer, which is arranged in the tower body , Located above the flue gas inlet and below the sprinkler, the porous equalizer includes a porous equalizer plate. The porous equalizer plate is provided with a plurality of airflow holes for the flue gas and slurry to pass through. The upper surface of the flow plate receives the slurry sprayed by the sprayer and forms a liquid holding layer. When the flue gas passes through the liquid holding layer, "bubbling" occurs, thereby effectively...

Embodiment 2

[0037] Compared with the first embodiment, the improvement of the second embodiment is that in the desulfurization and dust removal absorption tower with porous homogenizer in the second embodiment, the number of sprayers and porous homogenizers are both multiple, and the number of spray The shower and the porous homogenizer are arranged at intervals, and a porous homogenizer is correspondingly arranged under each shower. In this embodiment, the shower includes a plurality of nozzles, and the plurality of nozzles are evenly distributed above the porous homogenizer.

[0038] In this embodiment, each sprayer only sprays the slurry on the porous homogenizer located below it, so that a liquid holding layer is formed on the porous homogenizer of each layer of the porous homogenizer, and the flue gas is in the tower. The body passes through a multi-layer porous homogenizer to make the flue gas evenly distributed in the body, and then passes through the multi-layer liquid holding layer,...

Embodiment 3

[0040] Compared with the first embodiment, the improvement of the third embodiment is that, in the desulfurization and dust removal absorption tower provided with a porous homogenizer in the third embodiment, the porous equalizer closest to the flue gas inlet of the tower body The device is a first multi-hole current equalizer, the first multi-hole current equalizer includes a first multi-hole current equalizer, the first multi-hole current equalizer is obliquely arranged in the tower body, which is close to the side of the flue gas inlet It is higher than the side away from the flue gas inlet of the tower.

[0041] In this embodiment, the inclination angle of the first porous flow sharing plate in the tower body is 15°-25°; the first porous flow sharing plate is an elliptical plate, and the side wall of the elliptical plate is connected to the inner wall of the tower body. Laminated; the first porous flow-sharing plate is provided with a plurality of first airflow holes, the por...

Abstract

The invention discloses a desulfurization and dedusting absorption tower with a porous current equalizer. The desulfurization and dedusting absorption tower comprises a tower body, at least one sprayer and at least one porous current equalizer, wherein the tower body is provided with a flue gas inlet and a flue gas outlet; the sprayer is arranged in the tower body, is positioned between the flue gas inlet and the flue gas outlet and is used for spraying slurry; the porous current equalizer comprises a porous current equalizing plate, is arranged in the tower body and is positioned above the flue gas inlet and above the sprayer, and a plurality of airflow holes for flue gas as well as the slurry to pass through are formed in the porous current equalizing plate; when the desulfurization and dedusting absorption tower is in use, the upper surface of the porous current equalizing plate receives the slurry sprayed by the sprayer and forms a slurry holding layer; when the flue gas passes through the slurry holding layer, a bubbling phenomena occurs, so that the contact area and the contact time between the flue gas and the slurry in the slurry holding layer are effectively increased, the slurry can fully absorb sulfides in the flue gas as well as dust, and further, the desulfurization and dedusting efficiency of the desulfurization and dedusting absorption tower is effectively improved.

Description

Technical field [0001] The invention relates to the technical field of flue gas desulfurization and dust removal, in particular to a desulfurization and dust removal absorption tower provided with a porous homogenizer. Background technique [0002] In recent years, the use of wet desulfurization technology in the domestic power, non-ferrous and steel industries has become more and more common, and wet desulfurization will cause haze and acid rain to a certain extent. SO 2 Excessive emission of PM2.5 and PM2.5 has caused a bad impact on the atmospheric environment and seriously endangers national health. In this context, the country began to implement GB13223-2011 "Emission Standards for Air Pollutants for Thermal Power Plants", and implemented ultra-low clean emissions of thermal power plant flue gas in some power plants along the east coast, resulting in existing domestic enterprises that use wet desulfurization They are all facing the pressure of terminal treatment transformati...
