Abstract
Abstract An improved apparatus for removing mist or the like from a gas flow is described herein, in which a gas flow is introduced from a main duct into a lateral duct that is connected to the downstream end of the main duct and which extends in a different direction from the main duct to thereby cause mist, dust or the like in the gas flow to deviate within the lateral duct, a remover plate for mist, dust or the like is disposed in the region just downstream of the junction between the main duct and the lateral duct into which the mist, dust or the like in the gas flow has flowed, and a mist eliminator is provided downstream of the remover plate.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
228 words
An apparatus for removing mist and the like from a gas flow, comprising a main duct and a lateral duct connected to the downstream end of said main duct extending in a direction different from that of said main duct for causing mist and the like in flowing gas introduced into the lateral duct from said main duct to deviate within the lateral duct toward the outer wall of the lateral duct extending from the radially outer part of the bend between the main duct and the lateral duct, a remover plate in said lateral duct on at least the outer wall of said lateral duct downstream of the bend between said main duct and said lateral duct at a position where a large portion of the mist and the like contained in the gas flow has moved close to the outer wall of the lateral duct for diverting the mist and the like out of the gas flow, said remover plate extending from the outer wall in a direction transversely of the lateral duct to the position where the flow of speed of the gas flow falls to about 1/3 of the highest flow speed in the flow speed distribution in a cross-section of the lateral duct at the position of said remover plate, and a mist eliminator in said lateral duct downstream of said remover plate.
Claim 2
Independent Claim
228 words
An apparatus for removing mist and the like from a gas flow, comprising a main duct and a lateral duct connected to the downstream end of said main duct extending in a direction different from that of said main duct for causing mist and the like in flowing gas introduced into the lateral duct from said main duct to deviate within the lateral duct toward the outer wall of the lateral duct extending from the radially outer part of the bend between the main duct and the lateral duct, a remover plate in said lateral duct on at least the outer wall of said lateral duct downstream of the bend between said main duct and said lateral duct at a position where a large portion of the mist and the like contained in the gas flow has moved close to the outer wall of the lateral duct for diverting the mist and the like out of the gas flow, said remover plate extending from the outer wall in a direction transversely of the lateral duct to the position where the flow of speed of the gas flow falls to about 1/3 of the highest flow speed in the flow speed distribution in a cross-section of the lateral duct at the position of said remover plate, and a mist eliminator in said lateral duct downstream of said remover plate.
Claim 3
Dependent Claim
25 words
An apparatus as claimed in claim 1, in which said lateral duct extends from said main duct at an angle of at least 90 degrees.
Claim 4
Dependent Claim
40 words
An apparatus as claimed in claim 1, in which the main duct and the lateral duct are positioned horizontally and said mist remover plate extends peripherally of said lateral duct at least along the outer wall of said lateral duct.
Claim 5
Dependent Claim
37 words
An apparatus as claimed in claim 1, in which said main duct and said lateral duct are positioned horizontally and said mist remover plate extends from the outer wall and the bottom wall of said lateral duct.
