DEVICE OF THE AUTOMATIC CONTROL OVER THE REACTOR OF THE SEMICONTINUOUS OPERATION Russian patent published in 2007 - IPC B01J8/00 

FIELD: control over the reactor of the semicontinuous operation.

SUBSTANCE: the invention is pertaining to the field of the control over the reactor of the semicontinuous operation (RSCO) at the simultaneous batching of two components and is pertaining, in particular, to the regulated delivery of the different-phase components in the pulsed mode according to the parametric program as the function of the running value of the generalized parameter considering the electrical conductivity and the dielectric permittivity. The automatic control device RSCO, contains the consumption tank for the liquid component, the loose component hopper supplied with the screw feeder and the vibration stimulator of the consumption with the scanning frequency and the amplitude controlled by the static converter in the reactor supplied with the anchor and two propeller agitators, the level and pressure sensors in the consumption tank, the strain meter of the weight of the hopper with the loose component, the cutoff valves of feed of the liquid component delivery in the reactor, the electropneumatic transducers (EPT) intended for control over the pneumatic drives of the valves, the microprocessor controller intended for the programmable realization of the functions of the pulse-frequency batching and the pressure regulator operation in the consumption tank, for formation of the control signals delivered to the electropneumatic transducers and through the appropriate automatic starters of the four-channel block to the electromotors of the agitators of the reactor, the screw feeder, and through the static converter of the frequency and the amplitude to the vibrational stimulator of the consumption. The consumption tank is supplied with the lower drain connection pipe and the upper three-way control valve. The lower drain connection pipe is shifted concerning the axis of the consumption tank, lifted by the slant cut of then inlet section with respect to the bottom of the consumption tank and through the appropriate cutoff valve controlled by the static transducer is coupled to the inlet of the batcher. The batcher is made in the in the form of the bypass cylinder with the floating piston and the conical butt parts with the shutting ball valves and it is supplied with the three-connection pipes left-side and right - side collectors, the central connection pipes of which are connected to the axial holes of the conical butt parts of the by-pass cylinder, the lower connection pipes are connected to the outlet holes of the inlet three-way valve (TWV), and the upper connection pipes are coupled to the inlet openings of the outlet TWV. The inlet of the TWV is series-connected through the appropriate cutoff valve with the lower drain connection pipe of the consumption tank, and the outlet of the outlet TWV is coupled to the first connection pipe of the reactor, and the outlet of the screw feeder is connected to the second connection pipe of the reactor. At that the outputs of the sensors of the temperature, the level of pressures and of the strain-gauge transducer of the weight are connected accordingly to the first, the second, the third and the fourth inputs of the microprocessor controller. The invention provides, that the device contains the high-frequency sensor of the electrical conductivity of the reaction mass, two terminal switches mounted on the bodies of the inlet and outlet of the TWV of the batcher. At that the output of the sensor of the electrical conductivity is connected to the fifth input, the output of the final switch of the inlet TWV of the valve of the batcher is coupled to the sixth input, and the output of the final switch of the outlet TWV of the batcher is directed to the seventh input of the microprocessor controller. At that the output of the high - frequency the sensor of the electrical conductivity is coupled to inlets used for change of the command to the pressure regulator and to the pulse generator.

EFFECT: the invention ensures the increased efficiency of the control over the reactor of the semicontinuous operation.
