Abstract: FIELD: technological processes. 
     SUBSTANCE: device contains technological cleaning positions in a solution of a technical detergent, rinsing with tap water from a solution of a technical detergent, rinsing in a rinse solution, drying with heated air and a rinse unit installed in a single frame, and a bath equipped with a overflow system and filter units. The detergent solution preparation unit contains tanks with heaters and sensors for monitoring the level and temperature of the washing solution, provided with a system for supplying the corresponding washing solution from the corresponding line, a check valve and a regeneration unit for the washing solution, the inlet of which through the filter is connected to the tank of the said detergent solution preparation unit, and the outlet is connected through the check valve to the bath, cleaning and washing positions contain ultrasonic transducers mounted on the radiating membrane, which is the bottom of the bath. The drying position comprises a fan connected to the drying chamber with a heated air temperature sensor through the heater. In the cleaning and washing positions, the output of the regeneration unit of the washing solution is connected via the air valve to the compressed air network for its impulse delivery into the interior of the filter elements. In the cleaning, washing and rinsing positions, at least, one cassette for accommodating the filter elements is inserted, comprising posts with a pipe installed on them, docked with check valves and a rotation unit and rotatable therein for the filter elements, to seal the detergent solution, pressurized air from the check valve into the internal cavity of the filter elements and pumping out of it through the filtration network of the filter elements into the bath with the detergent solution. The device contains one bath in cleaning, washing and rinsing position, connected to the detergent solution preparation unit containing detergent solution and rinse solution tanks. Before the technological cleaning position, the technological blast cleaning position is introduced, which purifies the internal surface of the equipment with an uncharged bath and cleans the filter elements and filter discs of increased contamination, when they are loaded into the bath containing the blasting system. The blast cleaning system has jet circuits designed to access jets with 100% coverage of the equipment internal surface. The device is equipped with a control panel with the software installed in it, including the programs marked on the control panel: "Filter cleaning", "Dirty filter cleaning" and "Equipment cleaning", and made with the possibility of an automated control process of the said technological positions through the control elements. Control elements include taps and a valve and are designed to include specified flows of working bodies with the required parameters, specified duration, sequence and automation of the cleaning process and with the possibility of adjusting cleaning programs and taking into account the condition of filter elements and filter discs, their contamination and pollution type by adjusting the operation mode of the control elements. 
     EFFECT: simplifying the device design, improving quality and reducing cleaning time.
