Abstract
Abstract A demister vane assembly particularly resistant to corrosion and capable of interchangeable organization into a multiplicity of area and geometrical configuration arrangements. The demister vane assembly is formed in a standardized shape of a reinforced plastic capable of withstanding the thermal and chemical environment of a wet scrubber system. The standardized shape is a flow diverting surface preferably formed as a Z-shaped vane having end platforms angled approximately 60* to the longitudinal axis of the vane, the platforms having lap joint shoulders and self-fixturing segments. By means of the standardized shape, the vanes may be arranged, both end to end as well as side by side, to yield any desired demister area and geometrical configuration.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
151 words
A demister vane assembly for a flue gas wet scrubber arrangement, said demister vane assembly comprising a first end platform, a gas flow diverting surface having a longitudinal axis and a transverse axis, the gas flow being substantially in the direction of said transverse axis, said flow diverting surface being joined to said first end platform so that the angle between said first end platform and said longitudinal axis is less than 90*, a second end platform, said second end platform being joined to said surface at the opposite end from said first end platform so as to be parallel with said first end platform, said first and second end platforms each having integral therewith lap joint shoulders on opposite sides of said end platforms and each having a self-fixturing assembly for connection to additional similar assemblies, said first and second end platforms and said surface being formed of reinforced plastic.
Claim 2
Dependent Claim
151 words
A demister vane assembly for a flue gas wet scrubber arrangement, said demister vane assembly comprising a first end platform, a gas flow diverting surface having a longitudinal axis and a transverse axis, the gas flow being substantially in the direction of said transverse axis, said flow diverting surface being joined to said first end platform so that the angle between said first end platform and said longitudinal axis is less than 90*, a second end platform, said second end platform being joined to said surface at the opposite end from said first end platform so as to be parallel with said first end platform, said first and second end platforms each having integral therewith lap joint shoulders on opposite sides of said end platforms and each having a self-fixturing assembly for connection to additional similar assemblies, said first and second end platforms and said surface being formed of reinforced plastic.
Claim 3
Dependent Claim
28 words
The apparatus of claim 1 wherein said self-fixturing assembly comprises a male projection on one lap joint shoulder and a female notch on the opposite lap joint shoulder.
Claim 4
Dependent Claim
24 words
The apparatus of claim 2 wherein said first and second end platforms and said gas flow diverting surface are formed as an integral structure.
Claim 5
Dependent Claim
21 words
The apparatus of claim 3 wherein said angle between said end platforms and said longitudinal axis of said surface is 60*.
Claim 6
Dependent Claim
19 words
The apparatus of claim 4 wherein said gas flow diverting surface is in the form of a Z-shaped vane.
Claim 7
Dependent Claim
102 words
A demister vane assembly for a products-of-combustion wet scrubber arrangement, said demister vane assembly comprising an integral flow diverting surface formed of a thermal and corrosion resistive material, said gas flow diverting surface having a Z-shaped vane with parallel end platforms integral therewith at the opposite ends thereof, said platforms being at an angle to the longitudinal axis of said Z-shaped vane other than 90*, said platforms having central portions from which lap joint shoulders extend in opposite directions and a self-fixturing means comprising a male projection on one lap joint shoulder and a female notch in the opposite lap joint shoulder.
