FIELD: chemical industry; devices of the automatic control over the reactor of the semi- continuous operation. ^ SUBSTANCE: the invention is pertaining to the field of the control over the reactor of the semi- continuous operation (RSCO) at the variable consumption of the liquid batched component. The device contains the service tank for the liquid batched component, the reactor supplied with the stirrer, the coiled pipe and the jacket, the heat converter located in the reactor, the level sensor mounted in the service tank, the electro-pneumatic digital transducers intended for control over the pneumatic drives of the cut-off and discharge valves, the static power supply. The device is additionally supplied with the static three-channel power source, the pressure and consumption sensors arranged on the pressure branch pipe of the batcher and the electro-conductivity in the reactor, the meters of the frequency and voltage of the power delivered to the engines of the batcher and the stirrer, and also the power consumed by the consumption indicator, the microprocessor controller intended for implementation of the functions of the cascade system of the temperature stabilization of the reaction mass in the reactor and the program-pulse-revercive system making regulation of the rate of rotation of the engine of the stirrer, and also forming the control actions delivered to the electro-pneumatic transducers and through the static three-channel power supply - to the engines of the batcher, the stirrer and the consumption meter. The technical result of the invention is reduction of the batching duration, the increased production of the target product, improvement of the product quality ratings. ^ EFFECT: the invention ensures reduction of the batching duration, the increased production of the target product, improvement of the product quality ratings. ^ 10 dwg, 1 tbl |
