Problems solved by technology
On the one hand, the existing desulfurization devices cannot meet the treatment of a large amount of flue gas containing sulfur and fluorine due to the short reaction process. On the other hand, for some flue gases with high dust content (such as steel plant Flue gas), unable to remove a large amount of dust in the early stage of the reaction, so that a large amount of dust enters the post-processing equipment, causing problems such as equipment blockage and difficulty in cleaning

Embodiment Construction
[0007] As shown in the figure, the flue gas desulfurization, defluorination and dust removal device of the present invention includes a reactor 1 with a two-stage structure and a casing 2 covering the periphery of the reactor; the flue gas enters the upper section of the reactor from the smoke inlet 3, and after shrinking Section 4 and the absorption liquid sprayed by the absorption liquid spraying device 5 undergo the first-stage absorption reaction, and then enter the dust removal chamber 7 from the disconnected part 6 of the two-stage reactor; in the dust removal chamber, most of the dust settles in the compartment at the bottom On the plate 8, when the dust accumulates to a certain amount, open the ash outlet 9 to clean it; the flue gas passing through the dust removal chamber enters the lower section of the reactor 1, and absorbs the dust sprayed by the contraction section 4 and the lower absorption liquid atomization spray device 5. The liquid undergoes the second-stage a...

The present invention belongs to the field of environment protecting apparatus, and is especially one kind of fume desulfurizing, defluorinating and dedusting apparatus. The apparatus includes a reactor embedded inside a casing, the reactor has fume inlet in the upper end and dewatering demister in the lower end and communicated to the casing cavity, and the casing is provided with fume outlet. Structurally, the present invention features the reactor separated into two sections, the dedusting cavity communicated to the part between the two sections, one partition board set in the bottom of the dedusting cavity to separate the dedusting cavity from the fume outlet, and one valve controlled ash outlet in the casing below the dedusting cavity. The present invention has high dedusting efficiency, and raised defluorinating and dedusting effect.
Description
technical field [0001] The invention belongs to environmental protection equipment and relates to a flue gas desulfurization, defluorination and dust removal device for flue gas purification. Background technique [0002] The existing coal-fired flue gas purification is mainly desulfurization. The desulfurization device generally includes a reactor nested in the shell. The reactor is equipped with an absorption liquid atomization spray device. The flue gas enters from the upper end of the reactor and is mixed with the fog. After the absorbed liquid (generally ammonia water) is reacted and absorbed, it enters the interlayer between the reactor and the shell through the dehydration demister at the lower end of the reactor, and then is output from the flue gas outlet provided on the shell. Chinese patent CN2414827Y and Chinese patent CN2517481Y disclose the flue gas desulfurization device with the above structure. On the one hand, the existing desulfurization devices cannot me...
