A kind of wet desulphurization high-efficiency demisting apparatus
Technical field
The utility model belongs to environmental technology field, relates in particular to a kind of wet desulphurization high-efficiency demisting apparatus.
Background technology
At present, through containing a large amount of water smoke in wet desulphurization device flue gas after treatment, directly discharge causes a large amount of losses of moisture, need to use demister that water smoke in flue gas is removed.Existing demister mainly adopts ripple packing as demist moisture-catcher, this demister has many shortcomings, that resistance is larger on the one hand, ripple packing demist poor effect on the other hand, usually there is waste gas water phenomenon, moreover the life-span of filler is limited, easily produce and stop up, need to frequently clean and change.
Utility model content
The purpose of this utility model is to provide a kind of wet desulphurization high-efficiency demisting apparatus, and it is high that it has demist efficiency, and the effective and not susceptible to plugging shortcoming of demist, to solve the problem that in prior art, wet desulphurization demister exists.
For reaching this object, the utility model by the following technical solutions:
A kind of wet desulphurization high-efficiency demisting apparatus, it is installed in desulfurizing tower, comprise lower demist assembly and upper demist assembly, described upper demist assembly is installed on the top of described lower demist assembly, and be provided with the deflector under oblique between the two, described lower demist assembly comprises by fixed part and is fixed on the taper cone barrel in desulfurizing tower, described taper cone barrel upper end open is less than lower ending opening, and the upper end of described taper cone barrel is connected with speed-raising cylinder, the upper end of described speed-raising cylinder connects cyclone plate flange, described cyclone plate flange upper end connects cyclone plate, described cyclone plate upper end connects top cover.
Especially, described fixed part adopts mounting flange, and described mounting flange is fixedly welded on the inwall of described desulfurizing tower.
Especially, described upper demist assembly is deflection plate demister, is filled with ripple packing in it.
Especially, the barrel dliameter of described speed-raising cylinder is less than the aperture of described taper cone barrel upper end open.
Especially, on the surface of described ripple packing, be furnished with multiple salient points, so that it is difficult for stopping up.
The beneficial effects of the utility model are, compared with prior art described wet desulphurization high-efficiency demisting apparatus adopts the dual demist of upper and lower demist assembly, and not only demist efficiency is high, and demist is effective; And be difficult for stopping up, save spray-water.
Accompanying drawing explanation
Fig. 1 is the structural representation of the wet desulphurization high-efficiency demisting apparatus that provides of the utility model specific embodiment 1.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the wet desulphurization high-efficiency demisting apparatus that provides of the utility model specific embodiment 1.
In the present embodiment, a kind of wet desulphurization high-efficiency demisting apparatus is installed in desulfurizing tower 1, comprise lower demist assembly and upper demist assembly, described upper demist assembly is installed on the top of described lower demist assembly, and be provided with the deflector 2 under oblique between the two, described lower demist assembly comprises by mounting flange 3 and is fixedly welded on the taper cone barrel 4 in desulfurizing tower 1, described taper cone barrel 4 upper end open are less than lower ending opening, and the upper end of described taper cone barrel 4 is connected with speed-raising cylinder 5, the barrel dliameter of described speed-raising cylinder 5 is less than the aperture of described taper cone barrel 4 upper end open, and the upper end of described speed-raising cylinder 5 connects cyclone plate flange 6, described cyclone plate flange 6 upper ends connect cyclone plate 7, described cyclone plate 7 upper ends connect top cover 8, described upper demist assembly is deflection plate demister 9, in it, be filled with ripple packing 10, on the surface of described ripple packing 10, be furnished with multiple salient points, so that it is difficult for stopping up.
When flue gas enters demister, because described taper cone barrel 4 upper end open are less than lower ending opening, the speed raising after taper cone barrel 4 of flue gas constriction in flow area enters speed-raising cylinder 5, the barrel dliameter of speed-raising cylinder 5 is less than the aperture of described taper cone barrel 4 upper end open, because constriction in flow area further raises speed and enters cyclone plate 7, then flue gas leaves cyclone plate 7 after eddy flow, now spin after whirlwind line motion of flue gas, clash into the lower surface of desulfurizing tower 1 inwall and deflector 2, after water smoke in flue gas clashes into barrel, Yan Tabi is to dirty, after the demist of lower demist assembly, flue gas enters deflection plate demister 9 and carries out further demist, water smoke flows into the bottom of desulfurizing tower 1 by the upper surface of deflector 2.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-mentioned example; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
