Abstract
Abstract Apparatus for separating gas from liquid droplets comprising a chamber arranged such that gas passes along a zigzag path between spaced vane plates and then through an outlet. Each of the vane plates has stepped shoulders to form a circuitous path along which the gas passes such that the gas will rub against and have maximum contact with the wall of the plates, depositing the droplets of liquid thereon. The droplets will fall to the bottom of the chamber where they may be removed at periodic intervals from the chamber. The gas passes from the chamber in a dry state, free of the droplets of liquid.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
233 words
Apparatus for separating droplets of liquid from gas flowing through a chamber having an inlet and an outlet comprising: first and second side plates in the chamber; first and second zigzag shaped vane plates; support means in the chamber supporting said first and second zigzag shaped vane plates between said first and second side plates and in spaced apart relation such that a zigzag shaped path is formed between said first and second vane plates, spacer means between said vanes plates, and means urging said vane plates into engagement with said spacer means, said zigzag shaped plates having one end communicating with the inlet of the chamber and another end communicating with the outlet of the chamber, said vane plates having points of inflection intermediate the opposite ends of each of said zigzag-shaped plates; each of said vane plates being shaped to form a series of zigzag shaped vane plate segments intermediate the points of inflection, each of said vane plate segments being shaped to form a series of substantially right angularly disposed surfaces arranged such that surfaces of discontinuity are formed and which define the zigzag shaped path between the points of inflection while forming pockets along each side of said zigzag shaped plates adjacent said surfaces of discontinuity; each of said vane plate segments comprising surfaces extending substantially parallel to said first and second side plates and surfaces disposed perpendicular thereto.
Claim 2
Dependent Claim
233 words
Apparatus for separating droplets of liquid from gas flowing through a chamber having an inlet and an outlet comprising: first and second side plates in the chamber; first and second zigzag shaped vane plates; support means in the chamber supporting said first and second zigzag shaped vane plates between said first and second side plates and in spaced apart relation such that a zigzag shaped path is formed between said first and second vane plates, spacer means between said vanes plates, and means urging said vane plates into engagement with said spacer means, said zigzag shaped plates having one end communicating with the inlet of the chamber and another end communicating with the outlet of the chamber, said vane plates having points of inflection intermediate the opposite ends of each of said zigzag-shaped plates; each of said vane plates being shaped to form a series of zigzag shaped vane plate segments intermediate the points of inflection, each of said vane plate segments being shaped to form a series of substantially right angularly disposed surfaces arranged such that surfaces of discontinuity are formed and which define the zigzag shaped path between the points of inflection while forming pockets along each side of said zigzag shaped plates adjacent said surfaces of discontinuity; each of said vane plate segments comprising surfaces extending substantially parallel to said first and second side plates and surfaces disposed perpendicular thereto.
Claim 3
Dependent Claim
81 words
The combination called for in claim 1 wherein the support means comprises: a lower support member having vertically extending portions and a laterally extending lower wall secured to an interior wall of the chamber; spaced lugs secured to the vertically extending portions of the lower support member to space the vane plates from the lower wall of the lower support member; and an upper support member having a laterally extending wall secured between the vane plates and the chamber's interior wall.
Claim 4
Dependent Claim
45 words
The combination called for in claim 2 wherein the laterally extending walls of the support members form a discharge compartment between the outlet and the discharge side of the spaced vane plates to direct gas through the outlet after it passes between the vane plates.
Claim 5
Dependent Claim
34 words
The combination called for in claim 2 with the addition of a drain line extending from the lower wall of the lower support to a point spaced from the lower end of the chamber.
Claim 6
Dependent Claim
44 words
The combination called for in claim 1 wherein the means urging said vane plates into engagement with the spacer means comprises: spaced attachment rods extending through the side plates and through the vane plates; and means to secure the rods to the side plates.
Claim 7
Dependent Claim
43 words
The combination called for in claim 5 wherein the rods extend through passages in the spacer means and are secured on the outer faces of the side plates by threaded nuts whereby the rods may be removed for disassembly of the vane plates.
Claim 8
Dependent Claim
47 words
The combination called for in claim 1 wherein the support means comprises: spaced first and second side plates; a jack plate; screw means threadedly secured to said first side plate, said screw means engaging said jack plate to urge said vane plates toward said second side plate.
