Interior, cooling device 502 cools down oxidation wind, in oxidation wind after cooling input slurry pool 200 to flue gas is absorbed after
Slurries are aoxidized.
Specifically, the quantity of column plate 105 and spray equipment 104 can voluntarily be set according to required desulfurization degree and flue gas flow
It sets, using flexible, the opening diameter and percent opening on column plate 105 can also voluntarily be set according to flue gas flow rate with smoke absorption rate
Fixed, in the present embodiment, spray equipment 104 is provided with three groups altogether, and column plate 105 is provided with two groups altogether, corresponding every group of spray dress
It sets 104 and is separately provided with one group of circulating line 300.
As shown in Figure 2, the difference with the first embodiment is second of embodiment on this combined type absorption tower
The bottom surface 201 of slurry pool 200 is diminishing circular conical surface from top to bottom, and outlet is equipped at the vertex of a cone of the circular conical surface, and outlet is logical
It crosses circulating line 300 to connect with spray equipment 104, before circulating pump 302 is equipped in the circulating line 300 and is located at circulating pump 302
The first valve 301, circulating pump 302 can by slurries from slurry pool 200 be sent into spray equipment 104 in spray.
Using this structure, since the bottom surface 201 of slurry pool 200 is the conical surface with certain angle, the solid in slurries
It spontaneous can flow to without other site depositions in bottom surface 201 at the cone top part of the conical surface, and because at cone top part and recycle
Pipeline 300 connects, and the solid of deposition can be inhaled into circulating line 300 under the suction of circulating pump 302, and along circulation
Pipeline 300 is entered spray equipment 104 again and is sprayed, as long as therefore circulating pump 302 maintain to open always, consolidating in slurries
Body can just maintain circulation without accumulating always, go to be stirred without blender 600, compared to traditional absorption tower
Component is simplified, efficiency is improved.
201 periphery of bottom surface is additionally provided with the supporting walls 202 for extending below 201 bottom end of bottom surface vertically downwards, supporting walls 202
It is connected with ground, such structure makes 201 bottom end of bottom surface have certain distance far from ground, there can be enough spaces that placement is gone to follow
Endless tube road 300, the supporting walls 202 are equipped with the aperture stretched out for circulating line 300.
It for easy access and safeguards, recovery channel 400 is also connected on the circulating line 300 for slurries to be discharged, is recycled
