Modular air scrubber system
First Claim
1. A modular air scrubber system for removal of pollutants from air comprising:
- a plurality of individual scrubbing towers adapted for side-by-side interconnection and disconnection for providing multiple stage contacting of air to be treated with one or more scrubber solutions, each tower comprising a lower scrubber solution reservoir portion, a submersible pump mounted within said reservoir portion, and an upper portion containing contact media, each tower further comprising air inlet and air outlet means, and scrubber solution inlet and scrubber solution outlet means, wherein each tower comprises a substantially L-shaped housing having vertical and horizontal extensions corresponding substantially to said upper and lower portions, respectively, wherein said vertical extension is provided with a first removable cover for access to said contact media and said horizontal extension is provided with a second removable cover for access to said scrubber solution reservoir.

Abstract
A modular air scrubber system is provided for removal of pollutants from air and includes a plurality of modular scrubbing towers adapted for side-by-side interconnection to provide multiple stage filtering of air to be treated, each tower having a lower reservoir portion for a scrubber solution, and an upper portion containing contact media, each modular tower also provided with air inlets outlets and scrubber solution inlets and outlets.
A specific arrangement of these modules adapted to accommodate a counterflow arrangement of air and scrubber solution for the removal of hydrogen sulfide from air is disclosed, in conjunction with a scrubber solution feed and control unit.

8. A modular air scrubber system for removing pollutants from air comprising at least three stand-alone, self-contained, modular scrubber towers detachably connected in side-by-side and operative relationship, and including a first end unit, an intermediate unit, and a second end unit, each of said units including an upper portion enclosing contact media and a lower portion containing a scrubbing solution reservoir;
- the system further including means for introducing air to be treated into said first unit and for passing the air successively through the contact media in the first end unit, intermediate unit and second end unit; and
means for simultaneously introducing a scrubber solution into the second end unit and for passing the scrubber solution successively through the contact media in the second end unit, intermediate and first end unit, wherein said means for introducing air includes an inlet in the scrubbing solution of the first end unit, but above the scrubber solution in the reservoir, and wherein said means for passing the air through the first end, intermediate, and second end units comprises a first air opening between upper portions of the first end and intermediate units, and a second air opening between upper portions of the intermediate and second end units, and substantially vertical partitions in each of the intermediate and second end units adjacent said first and second openings. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
- the system further including means for introducing air to be treated into said first unit and for passing the air successively through the contact media in the first end unit, intermediate unit and second end unit; and
-
17. A free standing, self-contained, modular scrubber tower for use in an air treatment system, said tower including an L-shaped plastic housing including an upper portion and a lower portion, the upper portion including a column of contact media, and the lower portion including a scrubber solution reservoir;
- a submersible pump located in said reservoir;
said tower further including air inlet and outlet means, liquid inlet and outlet means, and means for discharging scrubbing solution onto said contact media for flow in a direction opposite the flow of air to be treated;
said tower further including a removable cover in said upper portion for access to said contact media. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
- a submersible pump located in said reservoir;
