Description
Technical field
The utility model relates to a kind of parallel waveform demister, mainly can be used for the means of flue gas desulfurization of power plant system or other need carry out the occasion of gas dewatering demist.
Background technology
The demister of existing desulphurization system generally includes shell and separating layer on the air-flow cross section in the enclosure is set, described separating layer is generally one deck, two-layer or three layers, every layer of separating layer constitutes by some demist plates spaced apart, leave distance between each demist plate, the gas channel of separating layer is passed in formation, described demist plate can be swash plate, flap or corrugated plating usually, when air-flow passes described separating layer, wherein contained water droplet is with the collision of demist plate or contact the back attached on the demist plate, realizes removing the purpose of water smoke thus.The defective of prior art is to be easy to be blown afloat by air-flow attached to the water on the demist plate, reenters in the air-flow, forms reentrainment, and influence removes fog effect.For addressing this problem, people often adopt the mode that reduces wind speed to reduce the reentrainment of air-flow to water, must strengthen equipment volume but do like this, increase the production cost and the space hold of equipment.
The utility model content
For overcoming the above-mentioned defective of prior art, the utility model provides a kind of parallel waveform demister, and this demister is not prone to the reentrainment phenomenon, and demist is effective, and volume is little, and cost is low.
The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of parallel waveform demister, comprise shell and the some settings separating layer on the air-flow cross section in the enclosure, described separating layer is made of some demist plates spaced apart, and described demist plate is provided with concavo-convex drain structure.
Because the utility model is provided with concavo-convex drain structure on the demist plate, improved on the one hand in the air-flow water droplet with demist plate possibility of collision and impact strength, make water droplet be easier on the demist plate, adhere to, collect in the groove attached to the water on the demist plate on the other hand, and flow down, greatly reduced the possibility of reentrainment along groove, not only improved thus and removed fog effect, but also allow higher wind speed, and reduced equipment volume, reduced production cost.

When described flap had two bendings, two wrap direction generally should be opposite, and promptly two bending parts are protruding in the opposite direction.
Each drain structure on the described same flap (or demist plate of other shapes) can adopt the form of convex-concave alternate (it is alternate that any one side of slave plate is seen as convex-concave) to distribute.
Described drain structure can be inverted V-shaped, and promptly its summit is respectively extended a straightway from the summit to the oblique below of both sides last.
Drain structure on the described flap can adopt impact style to process usually, and same drain structure sees to see to be exactly convex from another side when being concavity from the one side of flap, and vice versa.
The groove depth of described drain structure (depth of groove of seeing from concave surface) can be the 30-40 millimeter.
Described separating layer can be spliced by some demist plate assembled units, described demist plate assembled unit can be provided with several connecting rods, each flap of each unit (or other forms of demist plate) is fixedly connected on the connecting rod of each unit, forms a whole unit thus.
Can be provided with the beam of some cross direction profiles in the described shell, described each demist plate assembled unit frame respectively and can tighten together with beam by modes such as bolts on the beam of both sides separately.Each demist plate assembled unit with one deck is stitched together mutually, covers whole gas channel section, and the air-flow through this section must all pass this separating layer thus.Be understandable that the position of described each beam and distribution mode should meet the installation and the splicing requirement of each demist plate assembled unit.
Described each separating layer can also be provided with some water injection systems of washing usefulness separately, so that the dirt that will be deposited on the demist plate rinses out, to keep the demist efficient of demist plate.Described water injection system can comprise plurality of nozzles 6 and the feed pipe that is connected nozzle, described nozzle can be distributed in corresponding separating layer above or below, the nozzle spray direction that wherein is positioned at separating layer top down, the nozzle spray direction that is positioned at separating layer below up so that wash separating layer effectively.
