Described feeding mechanism is made up of clog-free disintegrating machine (19), additive funnel (20), belt conveyor (21) and conveying worm (22), and the outlet of described conveying worm is positioned at pyrolysis chamber (1) side, top.
2. melting incineration system as claimed in claim 1 carries out a technique of burning, and its processing step is as follows:
2.1 premixes to be burned are broken by the clog-free disintegrating machine (19) in feeding mechanism, feed in raw material from additive funnel (20) toward belt conveyor (21), drop to conveying worm (22) again sends into pyrolysis chamber (1); Simultaneously, be arranged on three plasma electrode (100) energising work in melter (2), the ultra-high temperature field of flame kernel temperatures as high 5000 DEG C is produced in melter (2), under the state of anaerobic or hypoxemia, melt premix rapidly, make the noble metal in premix be molten condition;
2.2 a large amount of heats enter into by radiation and the mode of high-temperature flue gas (25) thermal convection current the oil gas (28) that pyrolysis chamber (1) makes the organic cracking of this region premix become content of organics high, these oil gas enter fuel delivery and petroleum vapor recovery part by pipeline, oil gas (28) after the ammonia depickling in ammonia storage tank (12) again through cyclone dust removal machine (11) dedusting, oil gas condensation separator (9) condensation, the oil be separated enters fuel tank (8) and stores, and be a combustion room (3) by oil transfer pump (7) and oil-gas burner (6), dual firing chamber (4) provides fuel oil (30), the gas be separated enters oil-gas burner (6) burning,
2.3 simultaneously in combustion room (3) and dual firing chamber (4), by the uncombusted material (29) that the mode of directly burning is eliminated expendable fuel gas in high-temperature flue gas (25) and fallen from pyrolysis chamber (1), and the heat that burning produces is fed back to melter (2) as heat supplement, during continuous seepage, the heat that high-temperature flue gas (25) burning produces concentrates release in melter (2), be enough to the operating temperature of maintenance melter at 1200-1600 DEG C, now plasma electrode (100) quits work, thus reach energy-conservation effect,
The high-temperature flue gas (25) that 2.4 other unburneds fall enters high-temperature flue gas cooling and dedusting part by smoke chamber (5), by cyclone dust removal machine (11), preheated air (27) and low-temperature flue gas (26) is become after entering accumulation of heat quencher (14) cooling after gravitational precipitator (13) dedusting, a combustion room (3) is fed back to combustion-supporting through the preheated air (27) of accumulation of heat quencher (14) heat exchange, low-temperature flue gas (26) continues through cyclone dust collectors (15), catalytic adsorption device (16), after another cyclone dust collectors (15) and water drench tower (17), discharge outside eventually through chimney, wherein accumulation of heat quencher (14) is communicated with outside atmosphere.
