Arrangement, several sinusoidal pattern demisting blades are vertically installed on the blade fixture at equal intervals.
Further, the top surface of the demister is disposed with one or more blade fixtures, and the blade fixture is major axis
Support, several mounting holes are provided with along the long axis frame, for installing the sinusoidal pattern demisting blade.
Further, the sinusoidal pattern demisting blade includes the flat part and central arch part of its both sides, the sinusoidal pattern
The side flat part of demisting blade is arranged on the blade fixture of demister top surface, and its clipping room is away from for 25mm.
Further, the sole arrangement of the demister has one or more blade fixtures, and the top surface of the demister
Or the blade fixture that bottom surface is arranged is no more than 4.
Further, the opposite side flat part of the sinusoidal pattern demisting blade is arranged on the blade fixture of demister bottom surface
On.
Further, the demister by the both ends buckle of the blade fixture, be bonded or be welded on cylinder inboard wall,
Or it is bonded or is welded on cylinder inboard wall by the both ends of sinusoidal pattern demisting blade.
Further, the cross section of the cylinder is circular, regular hexagon or square.
Further, when the cylinder cross section for circular or regular hexagon when, the sinusoidal pattern demisting blade is from leaf
The centre of plate clamp is symmetrically mounted on blade fixture successively from big to small towards the both ends of blade fixture according to length of blade.
Further, the demisting separator is arranged on above the spraying layer in desulfuration absorbing tower.
The beneficial effects of the utility model are：
Demisting separator described in the utility model is constituted by demister in cylinder vertical direction to be removed by sinusoidal pattern
The Novel flue gas demisting passage that mist blade arrangement is formed.The demister can be dismantled flexibly, convenient cleaning and maintenance.By anti-
After corrosion treatment, the flue gas demisting passage formed by sinusoidal pattern demisting blade arrangement can be optimal the premise of defogging effect
Under take into account structural strength, cost of manufacture and maintenance convenience, overcome completely old demister structural strength, defogging effect,
Production cost and safeguard the defects of aspect of convenience four can not be taken into account.In addition, the demisting separator also has reality simple in construction
With easy to operate, cost is cheap, the advantages that being easy to popularize.
