Background technology
The patent No. is that the Chinese utility model patent of ZL200920286171.X discloses a kind of tubular type demister and demister.In above-mentioned patent, the tubular type demister comprises two-layer at least parallel pipe row, and pipe row be made up of evenly distributed pipe, supports respectively onboard at the two ends that pipe is arranged, and the direction of flue gas stream is perpendicular with the axis direction of the interior pipe of pipe row.Demister comprises above-mentioned tubular type demister, the tubular type demister is arranged in the upstream position of fume desulfurizing tower or horizontal flue, be furnished with at least a in dull and stereotyped demister, individual layer roof demister, two-layer roof demister, the rhombus demister at the downstream position of fume desulfurizing tower, perhaps the downstream position at horizontal flue is furnished with dull and stereotyped demister.
The tubular type demister of said structure and the demist efficient of demister and self-cleaning ability can't meet the demands in some cases, can't effectively eliminate the effect of big droplet and uniform flue gas simultaneously.
Summary of the invention
Purpose of the present invention provides a kind of tubular type demister and demister device, can further improve demist efficient and self-cleaning ability.
In order to achieve the above object, a kind of technical scheme of the present invention has provided a kind of imitative water droplet shape tubular type demister, it is characterized in that, comprise two-layer at least parallel imitative water drop shaped tube row, imitative water drop shaped tube row is that the pipe of water droplet shape is formed by evenly distributed cross section, imitative water drop shaped tube row's two ends are supported respectively onboard, and the direction of flue gas stream and the axis direction of pipe are perpendicular.
Another kind of technical scheme of the present invention has provided a kind of demister, it is characterized in that, comprise above-mentioned imitative water droplet shape tubular type demister, imitative water droplet shape tubular type demister is arranged in the upstream position of fume desulfurizing tower or horizontal flue, be furnished with at least a in dull and stereotyped demister, individual layer roof demister, two-layer roof demister, the rhombus demister at the downstream position of fume desulfurizing tower, perhaps the downstream position at horizontal flue is furnished with dull and stereotyped demister.
Imitative water droplet shape pipe of the present invention is arranged in the composition pipe row of delegation according to certain spacing, because pipe is evenly distributed, for the certain influence of circulation generation of flue gas, makes the gas of original disorder can become equally distributed relatively mobile.In addition, because the shape factor of imitative water droplet shape pipe can only be retained a spot of droplet and pile up on the pipe end face.But the wedge shape of imitative water drop shaped tube is arranged concrete good drain function downwards, and the flushing water in all simultaneously tubular type demister downstreams all has flushing action to the tubular type demister, has solved the risk of the many and less scaling obstruction of tubular type demister interception slurries like this.
Advantage of the present invention is: except the advantage that keeps original tubular type demister, the imitative downward layout of water drop shaped tube wedge shape can reduce the resistance of windward side, so, the fluid of walking around imitative water drop shaped tube side will reduce separation losses, reduce the flow resistance of part.And the side of imitative water drop shaped tube is bigger than cylindrical tube, when the up and down two-layer dislocation of pipe row of imitative water drop shaped tube demister is arranged, can increase the area of interception droplet, improves and removes fog effect.The wedge shape of imitative water drop shaped tube is arranged downwards in addition, and wedge grip has the guiding moisture film to drip fast, and is less scaling.
