ABSTRACT:
A three-bed regenerative fume incinerator system includes a single rotary fluid control valve which effects three operational cycles in a repeating sequence. A valve body has a cylindrical inner surface about a central axis. Six main conduit connection openings at 60.degree. angular intervals are organized as three regenerator connection openings and three interspersed functional connection openings. The regenerator connection openings are connected via conduits to the lower end of the three respective thermal regenerators, the upper ends of which are connected to a common combustion chamber. Respectively connected to the functional connection openings are a contaminated feed gas inlet, treated gas outlet, and a source of purge gas. A valve rotor within the body has a pair of generally parallel plates spaced apart a distance corresponding to the angular extent of the openings, and supported substantially equidistant from the central axis for rotation between three functional valve positions. When the valve rotor is in any one of the functional valve positions, the parallel plates define a first path between the plates for deliberate fluid communication between two diametrically opposed main conduit connection openings, a second path on the outside of one of the plates for deliberate fluid communication between two adjacent main conduit connection openings, and a third path on the outside of the other one of the plates for deliberate fluid communication between another two adjacent main conduit connection openings.
