Example Embodiment

[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 shell 2 surrounding the reactor; flue gas enters the upper section of the reactor from the flue gas inlet 3 and undergoes shrinkage. The absorption liquid sprayed by section 4 and the absorption liquid atomization spray device 5 undergoes the first-stage absorption reaction, and then enters the dust removal chamber 7 from the disconnected part 6 of the two-stage reactor; most of the dust in the dust removal chamber settles on the bottom partition On the board 8, when the dust accumulates to a certain amount, open the ash outlet 9 for cleaning; the flue gas passing through the dust removal chamber enters the lower section of the reactor 1, and is sprayed and absorbed by the contraction section 4 and the lower section of the absorption liquid atomizing spray device 5 The liquid undergoes the second-stage ...

Abstract

The invention belongs to the field of environment protection equipment, and relates to a device for flue gas purification, wherein the device can remove sulfur, fluorine, and dust from flue gas. The device comprises a reactor, which is nested in a shell; the upper end of the reactor is a glue gas inlet, the lower end of the reactor is communicated with the inner cavity of the shell through a water and mist remover, and the shell is provided with a flue gas outlet. The structure of the device is characterized in that the reactor is separated into two sections, a separating part is arranged between two sections of reactor, the separating part is communicated with a dedusting cavity in the upper part of the inner cavity of the shell; the bottom of the dedusting cavity is provided with an enclosed partition plate, which partially separates the dedusting cavity from the flue gas outlet arranged in the lower part of the inner cavity of the shell, and the shell of the lower part of the dedusting cavity is provided with an ash outlet which is controlled by a valve. The provided device largely reduces the dusts that enter the post-treatment equipment; thus the reliable operation of post-treatment equipment can be guaranteed, at the same time, the operation and maintenance are convenient, and the effect on removing sulfur and fluorine is improved.

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. On the one hand, due to the short reaction process, the existing desulfurization devices cannot meet the treatment of a large amount of flue gas containing sulfur and fluorine; on the other h...
