Abstract
The device of the present invention utilizes a unitized scheme to erect a sulphur dioxide scrubber tower wherein a set of factory built constituent subunits are joined at location to produce a single functional unit. The functional units themselves preferably are adaptable for parallel grouping as necessary to insure the treatment capacity required for the emission rate of any given application or where otherwise appropriate for other process reasons. The temporary strength and rigidity necessary to maintain a subunit's critical geometric integrity throughout construction, transportation and erection processes is provided by a reusable exoskeletal support cradle. Preferably each subunit is initially constructed upon such a cradle. Alternatively, subunits are constructed in jigs at the factory and transferred to the support cradles before shipping to the construction site. Each subunit is transported to location, rotated for erection, lifted into place and attached into assembly while still affixed to its cradle. Thereafter the cradle, having served its purpose, is removed and returned to the factory for reuse. The assembled functional unit has a minimal amount of internal members and relies upon cooperation between subunits to support the tower.
