Abstract
Abstract A gas cleaner incorporating a wet scrubber wherein the scrubber bed is made from self-contained basket-like modules which when in assembled relationship, are capable of carrying off water overflowing from the modules and thereby maintaining the desired turbulent level within the scrubber bed. The facing sides of adjacent modules are inclined inward so as to form a trough which catches the overflowing water, and which communicates with means for disposing of the overflowing water. A cover grill is provided for each bed module for the purpose of containing the filter material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
In combination with a gas cleaner of the wet scrubber type, the cleaner having a scrubber housing, a multi-sectioned bed of filter material positioned within said housing and a liquid spraying apparatus positioned within said housing for direction of liquid into the filter material of said bed, the improvement which comprises: a. a plurality of rectangularly shaped bed modules including plate means forming the sides of said modules, facing plates of adjacent modules being oppositely inclined to form troughs therebetween with said modules in assembled relation; b. means for mounting said modules within said housing; c. liquid discharge means for conducting overflow liquid from said modules into said troughs; and d. means for conducting overflow liquid from said troughs to an appropriate disposal place.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
20 words
The apparatus of claim 1 wherein said liquid discharge means is defined by the upper periphery of said side plates.
Claim 4
Dependent Claim
19 words
The apparatus of claim 1 wherein only one pair of opposite sides of each of said modules is inclined.
Claim 5
Dependent Claim
37 words
The apparatus of claim 1 wherein the bottom of each of said modules comprIses a corrugated plate supporting said filter material, said corrugated plates having a plurality of openings to allow flow of gas and liquid therethrough.
Claim 6
Dependent Claim
32 words
The apparatus of claim 1 wherein adjacent modules are assembled in abutting relationship, the facing inclined sides of said adjacent modules cooperating to form a trough having a substantially V-shaped cross section.
Claim 7
Dependent Claim
68 words
The apparatus of claim 1 wherein said mounting means comprises hanger structure including: a. a support fixed to said scrubber housing in overlying relation to said scrubber bed, b. at least one elongated rod fixed at one end to said support, and c. a bracket fixed to the other end of each of said rods and connected to the inclined sides forming said trough between two adjacent modules.
Claim 8
Dependent Claim
35 words
The apparatus of claim 1 wherein said liquid spraying apparatus is disposed within said housing adjacent to said bed and upstream from said bed with respect to the direction of gas flow in said cleaner.
Claim 9
Dependent Claim
37 words
The apparatus of claim 1 including a cover grill extending over the open upper end of each of said modules, said grill having openings which are smaller in size than the filter material contained in said modules.
Claim 10
Dependent Claim
41 words
The apparatus of claim 1 wherein said liquid discharge means is defined by a plurality of openings adjacent the upper end of the plates forming said troughs, said openings being smaller in size than the filter material contained in said modules.
Claim 11
Dependent Claim
61 words
The apparatus of claim 1 wherein said liquid discharge means comprises vertical portions extending above the plates forming the sides of said modules, at least one of said vertical extensions having a series of longitudinally aligned through slots disposed therein, said slots being sized so as to contain the bed filter material while allowing substantially unrestricted flow of overflow liquid therethrough.
