RRAU - Regenerative reactor of activated carbon

The rotary reactor of activated carbon is an experimental device for exploration of activated carbon pyrolysis is a batch method, heated by microwave, by electric heating, or by gas burner. 

The main element of this device is a rotary reactor, designed for pyrolysis of activated carbon. It is rotated at a very low speed (1-2 revolutions/min.) on a rolling cylinders. It has 2 inlet/outlet holes on both sides to fill/empty the reactor. Reactor caps are pressed through the pressure lever by means of an adjustable nut and a spring. Magnetrons inlet and outlet gases from the reactor is sealed with cast iron friction rings.

The reactor is placed in a furnace at a temperature of up to 900 ºC, which is tilted. The furnace cooling is enabled by opening the inlet valve under the furnace and removing the insulating cap on the furnace, or by switching on the ventilator, located in front of the valve.

Feeding the microwave to the reactor is through a magnetron channel through a magnetron tunnel and a magnetron glass. The magnetron channel is equipped with a nitrogen, steam and cooler inlet. The magnetron has its own source, which is cooled from the glycol circuit. Nitrogen is fed to the magnetron channel from the N₂ bottle through the control line. Steam development is provided by a laboratory flask and a heating nest. The overpressure water closure monitors the maximum steam overpressure of 1,5 kPa.

Arising gases from reactor are fed to a wet scrubber, where the gases are cooled and cleaned. Cooling water is cooled by glycol distribution in the room. The cleaned and cooled gases are disgarged into the chimney.
