NON-POLLUTING TREATMENT OF INDUSTRIAL WASTE CONTAINING CHLORINE

PURPOSE:To make industrial waste contg. chlorine non-polluting by separating materials contg. chlorine from the industrial waste, then adding these materials into a melting and refining furnace which utilizes electric energy, thereby melting and refining the materials. CONSTITUTION:An electrode seal 63 is disposed in the spacing between a furnace cap 4 and an electrode 6. A furnace body section 2 and this furnace cap 4 are air-tightly maintained from each other by a water sealing device 41, etc. A tunnel-shaped scrap charging port 8 is disposed and the leakage of in- furnace gases is prevented by double doors 82, 84. Further, a flue 14 for introducing the in-furnace gases into a secondary combustion chamber 16 is connected to the furnace cap 4. A mist separator 28, a gas heater 30, a bag filter 32 and an active carbon adsorption device 34 are disposed in a waste gas treating system to remove the gaseous chlorine, dioxine, etc., in waste gases. On the other hand, a waste water filter 20, an active carbon adsorption device 22, a neutralizing vessel 24 and a thickener 26 are disposed in a waste water treating system to recover cooling water.
