Abstract
An assembly of a quench liquid distribution ring and dip-tube with or without a draft tube for use in a hot effluent gas quench cooling zone containing a pool of quench liquid in the bottom in combination with a vertical cylindrical free-flow refractory lined reaction zone of a partial oxidation gas generator. The hot effluent gas from the reaction zone passes through a bottom central discharge outlet and passage and then through a coaxial vertical dip-tube that extends down into a pool of quench liquid. A quench liquid distribution ring that includes an annular rectangular shaped bottom feed quench liquid distribution channel, surrounds the outside diameter of the dip-tube at its upstream end. A quench ring face and cover is provided that comprises a vertical cylindrical shaped leg portion and a top horizontal flat ring plate portion that extends perpendicularly outward from the upstream end of the leg portion. The cylindrical shaped leg portion extends downward and overlaps the inside surface of the inner wall of said annular rectangular shaped quench liquid distribution channel thereby providing an annular shaped gap therebetween. The top horizontal flat ring plate portion provi…
