Description
(1) technical field
The utility model relates to depollution of environment facility field, particularly a kind of flue gas desulphurization system desulfurizing tower.
(2) background technology
In process of wet desulphurization, former flue gas reacts with the lime stone slurry sprayed through spraying layer and removes SO in absorption tower
2, the flue gas then mixing droplet and partial particulate thing again after demister demist through air flue emission.Because smoke components is complicated, after spraying layer, still a large amount of droplet and particle can be carried.The bending channel that flue gas consists of demister corrugated sheet with certain speed, under the effect of inertia force and gravity by the drop carried secretly in air-flow and particulate separation out, fall in slurry pool, achieve gas-liquid separation, make the flue gas flowing through demister reach demist and require rear discharge.If but the many and complicated component of flue gas particles, easily at demister corrugated sheet encrustation, affect demisting efficiency.And the general volume of demister is comparatively large, changes maintenance complicated, affect the desulfuration efficiency of bulk devulcanization tower.Simultaneously due to the back purge system of spraying layer and demister, also can make to carry a large amount of steam in flue gas, steam carries not by a small amount of SO that spraying layer absorbs
2or fine particle is with cigarette airflow exits, thus reduce desulfurization, demisting efficiency.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides the flue gas desulphurization system desulfurizing tower that a kind of desulfuration efficiency is high.
The utility model is achieved by the following technical solution:
A kind of flue gas desulphurization system desulfurizing tower, comprise tower body, demister and spraying layer is provided with in tower body, it is characterized in that, free rotary vane device is provided with above described demister, swirl-flow devices is provided with between described demister and spraying layer, described swirl-flow devices comprises the annular bottom plate be welded on tower body inwall, described annular bottom plate is provided with spout hole, spout hole lower end connects return duct, be provided with cover cylinder inside described annular bottom plate, described cover cylinder centre is provided with blind plate, is connected between described blind plate with cover cylinder by the swirl vane of some inclinations; Described free rotary vane device comprises and is welded on upper support frame on tower body inwall and lower support frame, longitudinal rotating shaft is provided with by bearing between described upper support frame and lower support frame, retaining ring is provided with outside described bearing, bearing outer end is provided with seal cover, in described rotating shaft, key is connected with runner, described runner is provided with the sector of some inclinations, and described sector is radially uniform along the circumference of runner.
The angle of described swirl vane and horizontal plane is 25 °.
The beneficial effects of the utility model are:
Because swirl vane tilts, therefore a flue tilted is defined between two pieces of adjacent swirl vanes, flue gas after spray just creates rotary motion by during swirl-flow devices again, the mist be mingled with in flue gas is just thrown toward cover cylinder inwall and flows down, when mist is more overflow from cover cylinder time, the mist overflowed gets off along spout hole and return line flow, avoids mist and enters demister and affect demisting efficiency, thus improve desulfuration efficiency; Vapor-separated water outlet in flue gas is come by the centrifugal force that can be produced by the rotation of blade that arranges rotating freely blade, avoids steam and enters with flue gas, therefore improve desulfurization, demisting efficiency.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is broken section structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of swirl-flow devices;
Fig. 3 is the annexation figure of wherein a slice swirl vane and blind plate
Fig. 4 is the annexation figure of wherein a slice sector and runner;
