A method of mixing a liquid and solids and apparatus therefor.

摘要

In a method of mixing a liquid and solids, the solids are fed into the liquid whilst the liquid is swirling about the surface of a converging chamber (18). The chamber (18) is defined by at least two frusto-conical portions (20, 22) disposed one above the other. The upper portion 20 has a substantially larger included angle than that of the lower portion (22). Inlet nozzles (44) are supplied from an annular plenum 42 and are arranged tangentially with respect to the upper end of the chamber (18) so as to induce swirling of the liquid injected into the chamber (18). Mixed liquid and solids from the chamber (18) are arranged to discharge into a vessel (14) having a vortex breaker at its outlet. <IMAGE>
