FIELD: incineration of waste. ^ SUBSTANCE: device comprises charging device, working chamber with plasma heaters, system for purifying combustion products and removing decomposition products, and system for automatic control. The working chamber is made of two plasma heaters which form reaction and combustion chambers which form flowing cylindrical passage. The passage receives the charging device provided with sealed valve and batcher for supplying waste. The system for purifying and removing decomposition products is made of liquid emulsifying device of vortex type provided with heat exchanger, settler, and smoke exhauster. The automatic control system is provided with indicating unit, control unit, unit for control of parameters of the plasma heaters, and system unit on the base of a computer. The decomposition process is performed with oxygen deficiency in the first reaction chamber in the plasma flow. The flow is generated by injecting electric-arc plasma from the external zone of the chamber. The air jets are set in rotation around their axes, whereas the plasma charge is set in rotation about the central electrode. The decomposition products are burnt up in the second chamber, expanded, cooled, and purified. The flow rates of waste, ejecting air, and purifying emulsifying liquid as well as the power of the arcs of the plasma generators are controlled in such a way to provide a given value of pH in the settler. ^ EFFECT: enhanced efficiency and ecological safety of the process. ^ 12 cl, 9 dwg |
