Embodiment 1

[0059] The dioxin removal system of the embodiment of the present invention is used to treat the waste high-temperature flue gas of a waste incineration treatment plant, wherein the structural diagram of the dioxin removal system is as follows figure 1 As shown, the specific method is as follows:

[0060] (1) Waste flue gas (800-900°C) enters through the flue gas inlet of the quenching tower, and the flue gas is rapidly cooled to 100-200°C by the cooling water sprayer, and the cooling water after heat exchange enters the cooling tower to cool down Return to the chilling tower, so as to realize the recycling of chilling water, and regularly remove the residual liquid accumulated in the chilling tower.

[0061] (2) The chilled low-temperature flue gas enters the parallel Venturi scrubber 200 in two ways, and the flue gas is mixed with the washing liquid in the throat of the Venturi scrubber 200. The scrubber diffuser section is removed. Thus, the removal of particulate impurit...

Abstract

The invention discloses a dioxin removal system and application of the dioxin removal system. The dioxin removal system comprises a chilling tower, a venturi scrubber, a washing solution storage tank, an active carbon adsorption tower and an active carbon storage bin. According to the dioxin removal system disclosed by the invention, dioxin is commonly removed through the chilling tower, the venturi scrubber and the active carbon adsorption tower; the problem that an existing dioxin removal device is single is solved; the dioxin is completely removed in one time and the removal rate of the dioxin is high.

Description

technical field [0001] The invention relates to a dioxin removal system and a method for treating flue gas using the aforementioned dioxin removal system. Background technique [0002] As a technology for dealing with urban waste, incineration technology has more outstanding effect on reduction, recycling and harmlessness than other technologies, and has been widely used in the world. A number of pollutants are produced, of which dioxins are considered to be the most toxic class of compounds. Dioxin is a general term for a class of substances, including polychlorinated dibenzodioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), which contain 75 species and 135 homologues. Dioxins are very stable compounds, colorless solids at room temperature, slightly soluble in most organic solvents, extremely difficult to dissolve in water, and have relatively high melting and boiling points. The formation mechanism of dioxin is mainly high-temperature gas phase formation, macrom...
