Combined high-effective wet desulfurization dust-removing equipment

Abstract

The combined high-effective wet desulfurizing dust-removing equipment includes lower dry type cyclone dust collector, its bottom portion is equipped with ash exhauster, ash discharging device and outward ash-exhausting cylinder, a lower external cyclone body is set on the outward ash-exhausting cylinder. It is characterized by that in the interior of outward ash-exhausting cylinder an internal ash-exhausting cylinder is set, on the internal ash-exhausting cylinder and in lower external cyclone body interior oa lower internal cyclone body is set, one side of lower internal cyclone body is equipped with guide vane, on the top plate or the lower internal cyclone body a tornadotron is set, and on the lower dry-type cyclone dust collector an upper wet desulfurizing dust-removing device is set,and said tornadotron is connected with upper wet desulfurizing dust-removing device.

Description

(1) Technical field:

[0001] The invention relates to the technical field of flue gas desulfurization and dust removal for industrial boilers, in particular to a combined high-efficiency wet desulfurization and dust collector which combines dry dust removal and wet desulfurization dust removal. (two) background technology:

[0002] At present, the flue gas desulfurization of industrial boilers generally adopts post-combustion desulfurization. Post-combustion desulfurization is divided into three types: dry method, dry-wet method and wet method. Among these three desulfurization methods, wet desulfurization is the most commonly used. The basic process of wet desulfurization It is to wash the flue gas with a desulfurizing agent solution in the desulfurization reaction tower, so that the two have a strong chemical reaction and mass transfer process, so as to remove the sulfide in the flue gas and achieve the purpose of purifying the flue gas.

[0003] The existing industrial boi...
