摘要： PURPOSE:To constitute a plasma melting device so that the dropping position of incineration ash in the bottom of a melting furnace is deviated from a position immediately below a plasma torch and melt the incineration ash by projecting plasma arc in a wide range. CONSTITUTION:A plasma melting device is provided with a throwing chute 6 of incineration ash, which is arranged at the middle part of two pieces of plasma torches 3 whereby plasma arc can be projected against a wide range and the flame failure of plasma is hardly caused. On the other hand, when an electrode, accommodated in one set of plasma torch 3, is replaced, the plasma arc can be generated from another plasma torch 3 whereby molten slag will never be cooled and solidified. The plasma melting device is provided with a torch oscillating device and, therefore, the projecting direction of the plasma arc can be changed by changing and regulating the inclination of the plasma torch 3.

摘要： PROBLEM TO BE SOLVED: To heighten the concentration of nonferrous heavy metal contained in smoke dust and to effectively reuse the smoke dust itself as nonferrous heavy metal material. SOLUTION: Waste gas 6 discharged from a melting furnace 1 is cooled by a gas cooler 2 to temperatures (150 deg.C-550 deg.C) at which the waste gas is introduced into a dust collector (using a bag filter) 3. Then smoke dust 7 contained in the waste gas 6 is removed by the dust collector 3. The smoke dust 7 contains a lot of nonferrous heavy metal and the collected smoke dust 7 is stored in a smoke dust storage device and is appropriately sent to a device for refining. Next, a powdery alkaline chemical 8 is added to the waste gas to remove acidic gas contained in the waste gas 6 from which the smoke dust 7 has been removed. And the powdery alkaline chemical 8 is removed and recovered by a dust collector (using a bag filter) 4.

摘要： PURPOSE:To prevent the adhesion of flying ash to a waste gas duct and the like by solidifying the ash and exclude the bad affection to a bag filter by diluting waste gas by a method wherein the waste gas from a melting furnace is cooled insantaneously before introducing it into the bag filter to shorten a time, in which gaseous flying ash in the waste gas is in the molten condition thereof. CONSTITUTION:In a plasma melting furnace 1, in which the melting treatment of incinerating ash is effected in a melting furnace 4, waste gas, generated from the melting furnace 4, is diluted by cooling air, by 5-50 times, and is introduced into a bag filter 14 whereby the mixture of salts such as NaCl and the like, which are the principal constituents of flying ash contained in waste gas, passes the molten condition thereof instantaneously in one breath and is changed from gas into solid instantaneously and, therefore, the adhesion of flying ash to the inner wall surfaces of a waste gas duct 12 and/or a gas cooler becomes hard and bad 1 affection to the bag filter can be excluded by diluting the waste gas.
