SOLVENT RECOVERY PLANT Russian patent published in 2023 - IPC B01D3/02 

FIELD: distillation equipment.

SUBSTANCE: device for distilling light fractions in boilers or distillation cubes that can be used in purification of solvents. The installation for regeneration of solvents contains a housing mounted on a frame on axes with the possibility of rotation and fixation in the normal and the tilted positions. A distillation tank is fixed in the housing, inside of which a temperature sensor is installed in its upper part. The distillation tank is equipped with an oil jacket and an upper sealed hatch. An oil heating element for heating diathermic oil and a temperature sensor are attached to the side surface of the distillation tank. To collect the condensing distillate, an outlet nozzle is fixed in the upper part of the tank and routed through the lower part of the housing. The nozzle is equipped with a coil and a fan for cooling the distillate. A temperature sensor is installed at the outlet of the coil to control distillate temperature. The installation control unit is fixed on the outer surface of the housing, while the outputs of the temperature sensors are connected to the measuring inputs of the control unit, and the power outputs of the latter are connected to the oil heating element and the fan.

EFFECT: automatic control of the solvent purification process and regulation of the installation's productivity.
