Embodiment Construction

[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0033] The invention provides a desulfurization equipment, such as figure 1 As shown, the desulfurization equipment includes a desulfurization tower body 100, and at least one group of atomizers 200 are arranged on the tower wall of the desulfurization tower body 100, and a plurality of atomizers in each group of atomizers 200 are arranged on the tower wall The top is arranged circumferentially along the tower wall, so that the slurry sprayed by each group of atomizers 200 forms a swirling flow in the desulfurization tower body.

[0034] In the desulfurization equipment provided by the present invention, the slurry sprayed in the desulfurization tower body 100 ...

Abstract

The invention discloses a desulfurization device comprising a desulfurization tower body (100). At least one set of atomizers (200) is arranged on the tower wall of the desulfurization tower body (100). A plurality of atomizers (200) in each atomizer set are circumferentially arranged on and along the tower wall, such that slurry ejected by each set of the atomizers form a swirl in the desulfurization tower body (100). With the desulfurization device provided by the invention, flue gas can be mixed well with the slurry; the contact time of the flue gas and the slurry can be prolonged; and a contact reaction of the flue gas and the slurry can be facilitated. Therefore, desulfurization efficiency can be improved, and circulating slurry utilization rate can be improved, such that circulating slurry demand can be reduced, and desulfurization energy consumption can be reduced.

Description

technical field [0001] The invention relates to desulfurization technology, in particular to a desulfurization equipment. Background technique [0002] With the rapid economic development and the sharp increase of total energy consumption, the problem of air pollution caused by SO2 emitted by industrial flue gas has become increasingly serious. Air pollution not only endangers the growth of animals and plants, destroys the ozone layer, but also causes problems such as acid rain and the greenhouse effect. Therefore, desulfurization of flue gas is an effective means to control SO2 pollution. [0003] At present, coal-fired boilers such as thermal power plants often use limestone-gypsum wet desulfurization technology to desulfurize SO generated during combustion. 2 For removal, the principle is: pass the tail flue gas into the wet flue gas desulfurization tower, use the slurry circulation pump to pressurize the limestone slurry in the slurry pool at the bottom of the desulfur...
