DEVICE FOR AUTOMATIC CONTROL OVER SEMI-CONTINUOUS ACTION REACTOR Russian patent published in 2007 - IPC G05D27/00 

FIELD: technology for controlling objects with non-stationary dynamics, possible use in industry during realization of heat-generating processes in semi-continuous action reactors.

SUBSTANCE: device contains controlled object itself with heat-exchanging devices in form of serially connected coat and coil, mixer with motor, unloading valve, devices for measuring temperature of reaction mass, flow of dosed component, rotation speed of mixer motor, adaptive block for reaction mass temperature controller, with adaptive compensators of perturbations, adjusting valve in the line for feeding dosed component into reactor, controllable mixer drive, consisting of motor and static block for controlling its speed. Branch pipe for feeding dosed component from repository vessel is connected serially through controlling valve and flow meter to force branch pipe, lowered below the mirror of reaction mass, directly into mixer operation zone. Output from flow meter of dosed component through integrator is connected to block for controlling rotation speed of mixer motor. Device additionally contains microprocessor controller, frequency meter for measuring rotation speed of mixer, electro-pneumatic analog transformer, positioned near the drive of controlling valve, adaptive controllers and compensators for considering oscillations of reaction mass temperature and flow of dosed component.

EFFECT: increased reliability of control over reactor and precision of stabilization of temperature mode.
