Abstract
Abstract A wet scrubber system is disclosed wherein the outer metal tank of the scrubber is protected from pitting and corrosion by providing an air gap between the tank and the acid resistant inner liner. A washing solution is cascaded in the space between the tank and liner along with a counter flow of oxygen containing gas to both wash and passify the metal surface.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
138 words
A wet scrubber tank for removal of pollutant gases and particulate matter, said tank comprising: an outer peripheral wall, an acid resistant lining wall axially mounted within said tank, fastener means connecting said peripheral wall to said lining wall so as to maintain them in spaced apart relationship thereby defining a space therebetween, conduit means located at opposite ends of said tank lining wall whereby gaseous effluent may be respectively introduced into and carried out of said tank, cascading liquid means communicating with and mounted adjacent to said space such that liquid flows downwardly therein, draft inducing means arranged in communicating relation with said space such that a gas flow passes therethrough in cooperative contacting relation to the cascading liquid, and washing means serving to direct the spray onto the pollutant gases and particulate matter in the effluent.
Claim 2
Dependent Claim
138 words
A wet scrubber tank for removal of pollutant gases and particulate matter, said tank comprising: an outer peripheral wall, an acid resistant lining wall axially mounted within said tank, fastener means connecting said peripheral wall to said lining wall so as to maintain them in spaced apart relationship thereby defining a space therebetween, conduit means located at opposite ends of said tank lining wall whereby gaseous effluent may be respectively introduced into and carried out of said tank, cascading liquid means communicating with and mounted adjacent to said space such that liquid flows downwardly therein, draft inducing means arranged in communicating relation with said space such that a gas flow passes therethrough in cooperative contacting relation to the cascading liquid, and washing means serving to direct the spray onto the pollutant gases and particulate matter in the effluent.
Claim 3
Dependent Claim
54 words
A wet scrubber tank as in claim 1 wherein said cascading liquid means and said draft inducing means are mounted on said tank in spaced relation to one another and in communicating relation with said space, whereby said cascading liquid and said induced draft flow within said space in countercurrent relation to one another.
Claim 4
Dependent Claim
41 words
The wet scrubber of claim 1 wherein a gas containing oxygen is forced up the space between said tank and said lining while concurrently a liquid is forced down said space whereby an aeration and washing operation is simultaneously carried on.
Claim 5
Dependent Claim
14 words
The wet scrubber of claim 1 wherein said acid resistant lining is acid brick.
Claim 6
Dependent Claim
24 words
The wet scrubber of claim 1 wherein means are provided to force oxygen containing gas through said space between said tank and said lining.
Claim 7
Dependent Claim
12 words
The wet scrubber of claim 1 wherein said tank comprises stainless steel.
Claim 8
Dependent Claim
23 words
The wet scrubber of claim 1 wherein said lining and said tank are held in rigid spaced relationship by a plurality of bolts.
Claim 9
Dependent Claim
16 words
The wet scrubber of claim 7 wherein said bolts are coated with an acid resistant ceramic.
Claim 10
Dependent Claim
33 words
The wet scrubber of claim 1 wherein liquid cascading means are provided at the top of said annular space between said tank and said lining whereby said space is washed by said liquid.
Claim 11
Dependent Claim
39 words
The wet scrubber of claim 9 wherein said tank is round and further wherein said cascading means is a torodial, apertured pipe affixed to the top of said tank and adapted to cascade said liquid down said annular groove.
Claim 12
Dependent Claim
11 words
The wet scrubber of claim 9 wherein said liquid is water.
Claim 13
Dependent Claim
16 words
The wet scrubber of claim 1 wherein said tank has a plurality of apertured baffle plates.
Claim 14
Dependent Claim
56 words
A wet scrubber as in claim 12 comprising at least two apertured plates in fixed, parallel spaced relationship wherein said plate apertures are of one of said plates are misregistered with respect to said adjacent plate whereby the space between said apertures of one plate act as baffles for a substance flowing through an adjacent plate.
Claim 15
Dependent Claim
18 words
The impingement plates of claim 13 wherein said each of said plates have 600-3,000 apertures per square foot.
Claim 16
Dependent Claim
17 words
The impingement plate of claim 13 wherein said plates are made of corrosion and erosion resistant substances.
