To provide a drive system that allows for smooth and reliable operation, is cost effective, and is low maintenance in a regenerative thermal oxidizer that utilizes a valve equipped with such a drive system.
The regenerative thermal oxidizer includes an electric drive for a switching valve, a switching valve having the drive, and a regenerative thermal oxidizer including the switching valve and drive system. The electric drive system allows for the starting and stopping of the rotation of a rotary valve with accurate positioning. The stopping of the valve includes dissipation of the kinetic energy of the valve by electric means. The valve is allowed to move vertically and oscillating rotary motion is possible. The drive system preferably includes a gear, gearbox, variable speed drive and at least one positioning sensor. Valve acceleration and deceleration can be carried out in a controlled fashion and with repeatability, so that the final end position of the valve is consistent. The accommodation of vertical movement of the valve is also within the scope.
