Abstract
Abstract An improved arrangement for an air pollution control system incorporating a wet scrubber wherein the scrubber bed is made in sections which are adjustably located within the scrubbing housing. The scrubber bed is formed of standard size modules and each module is supported within the scrubber housing for adjustment therein. The number of modules is dependent upon the preliminary design characteristics for the pollution control desired to be achieved for the particular combustion system, while the adjustability within the scrubber of the beds enables the beds to be repositioned for particular flow characteristics of the gas being scrubbed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
95 words
In an air pollution control system for controlling pollutants in gases resulting from combustion of fossil fuels, the control system having a scrubber housing and an overbed and underbed spraying apparatus within said housing, the improvement comprising: a multisection scrubber bed extending in a plane across said housing between said overbed and underbed spraying apparatus, both of said overbed and underbed spraying apparatus being directed toward said scrubber bed, and multiple independent adjustment means for selectively controlling the position of each of the scrubber bed sections with respect to said overbed and underbed spraying apparatus.
Claim 2
Dependent Claim
95 words
In an air pollution control system for controlling pollutants in gases resulting from combustion of fossil fuels, the control system having a scrubber housing and an overbed and underbed spraying apparatus within said housing, the improvement comprising: a multisection scrubber bed extending in a plane across said housing between said overbed and underbed spraying apparatus, both of said overbed and underbed spraying apparatus being directed toward said scrubber bed, and multiple independent adjustment means for selectively controlling the position of each of the scrubber bed sections with respect to said overbed and underbed spraying apparatus.
Claim 3
Dependent Claim
63 words
The apparatus of claim 1 wherein each of said independent adjustment means includes an elongated rod threaded at each end, a support fixed to said scrubber housing above the desired scrubber bed level and a threaded connector fixed to said scrubber bed, said elongated rod being adjustably connected to said support at one end and to said threaded connector at its other end.
Claim 4
Dependent Claim
45 words
The apparatus of claim 1 wherein each of said sections of said scrubber bed is a container having a base permitting the passage of gas therethrough and upstanding side walls for confining scrubber bed material, each of said sections being uniform in size and configuration.
Claim 5
Dependent Claim
70 words
The apparatus of claim 3 wherein said independent adjustable means includes elongated rods threaded at each end, supports fixed to said scrubber housing above the desired scrubber bed level, and threaded connectors connected to said scrubber bed sections, said elongated rods being adjustably connected to said supports at one end and said threaded connectors at the other ends thereof so as to enable the sections to be selectively independently adjusted.
