Description
Technical field
The present invention relates to a kind of demister and application thereof of how curved buckle blade, the demister of how curved buckle blade be arranged on wet electrical dust precipitator outlet or in the horizontal flue at its rear for purifying smoke, belong to smoke eliminator technical field.
Background technology
In order further to reduce the smoke content of absorption tower outlet, conventionally at outlet rear, absorption tower to wet electrical dust precipitator being installed for collecting flue gas fine particle thing and various dust thing between chimney.But because wet electrical dust precipitator is in the time moving, inside need to be sprayed a large amount of water and be come anode purge plate and cathode line, inevitably occur that in the outlet of wet electrical dust precipitator a large amount of drops enters rear flue and chimney with flue gas, then blow out by chimney, be commonly referred to the rain that wafts.How to reduce and reduce the drop amount that the flue gas of wet electrical dust precipitator outlet carries, we need to adopt demister equipment to remove the drop in these flue gases.
The demist efficiency that conventional demister is installed due to the outlet of wet electrical dust precipitator cannot meet the demands, need to adopt a kind of new and effective demister blade to remove a large amount of drops that carry in flue gas, the drop in the flue gas of the outlet of guarantee wet electrical dust precipitator and rear flue is the least possible.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of and had more than good draining function, interception drop and demister and the application thereof of the how curved buckle blade of less scaling obstruction, the flue gas that has solved wet electrical dust precipitator outlet carries a large amount of drops and enters together rear flue and chimney, the problem of the rain that occurs wafing.
In order to solve the problems of the technologies described above, technical scheme of the present invention has been to provide a kind of demister of how curved buckle blade, it is characterized in that, comprise at least 2 demister modules, between every 2 demister modules levels, be provided with a tank, each demister modules comprises at least 2 the how curved buckle blade and the draw-in grooves that are parallel to each other, more than at least 2, between curved buckle blade, is fixedly connected with by draw-in groove, and the wavy surface of each how curved buckle blade is provided with a hook.
Preferably, width range W=150mm～the 450mm of described how curved buckle blade, scope H=40mm～the 60mm of buckle wavy surface on described how curved buckle blade, circular arc angular range α=60 of described wavy surface °～120 °, thickness range t=2.5mm～the 3.5mm of described how curved buckle blade, length range L=1m～the 4m of described how curved buckle blade, the distance range J=20mm～40mm between the how curved buckle blade described in adjacent two.
A kind of application of demister of how curved buckle blade, it is characterized in that, have at least in the demister of curved buckle blade more than 1 is located in wet electrical dust precipitator outlet or is located at and exports with wet electrical dust precipitator the flue being connected, the width of the how curved buckle blade in the demister of each how curved buckle blade broadens gradually according to the direction that flows to of flue gas.
Preferably, the adjacent distance between curved buckle blade more than two in the demister of the how curved buckle blade of described each diminishes gradually according to the direction that flows to of flue gas.
Preferably, the wavy surface quantity on the how curved buckle blade in the demister of the how curved buckle blade of the flue gas described in contact is 1-3 at first, and the wavy surface on all how curved buckle blades amounts at least 2.
Preferably, the opening direction of described hook is the direction to flue gas just.
Preferably, described how curved buckle blade is vertically located in wet electrical dust precipitator outlet or in flue, and how curved the flue gas flow direction direction of buckle blade and level be orthogonal.
The demister of of the present invention how curved buckle blade has been realized the effect of tackling a large amount of drops.When for equipment actual motion, blade is the module that is vertically arranged in a line composition blind shaped according to certain spacing, evenly distributed due to blade, produces certain impact for the circulation of flue gas, makes original disorderly gas can become relatively equally distributed and flows.In addition, because blade is the shape factor of vertically placing, drop on the surface of blade under interception can not be retained and be piled up, there is good draining function, the multiple bending channels of blade are very effective for the interception of drop, and after the blade inlet place a large amount of drop of first passage is blocked, the drop passing through with flue gas can be tackled by second channel and third channel, until drop is all blocked, remaining droplet can flow out demister with flue gas.Make like this more than this demister interception drop and less scaling obstruction.
