Method and apparatus for injection of a liquid waste into a molten bath

Abstract

A method and apparatus are disclosed for injecting liquids into a molten bath. The method includes forming a suitable liquid dispersion of a liquid phase disposed in a gas phase. The liquid phase has a ratio of surface area to volume which is sufficient to cause an accumulated amount of the liquid phase in the molten bath to be significantly less than that which would occur by injection of a continuous stream of the liquid into the molten bath. The liquid dispersion is directed into the molten metal bath, whereby the liquid volatilizes or decomposes. The rate at which the liquid dispersion is injected into the molten bath is sufficient to cause the liquid of the liquid phase to volatilize or decompose at a rate which is sufficient to cause the accumulation of the liquid phase in the bath to be significantly less than that which would occur by injection of a continuous stream of the liquid into the molten bath. The apparatus includes an atomizer which is disposed at a reactor containing the molten bath. The atomizer can be, for example, a tuyere which atomizes a suitable liquid to form a liquid dispersion of the liquid in a gas. The liquid dispersion is directed into the molten bath through the tuyere for volatilization or decomposition of the liquid.
