Apparatus for separating liquid from gas
Abstract
Abstract THIS INVENTION RELATES TO AN APPARATUS FOR SEPARATING LIQUID WHICH MIGH CONTAIN SMALL PARTICLES OF SOLID MATERIAL FROM GAS, THE APPARATUS BEING MOUNTED AT THE UPPER PORTION OF A VERTICAL HEAT EXCHANGER AND COMPISING A FALSE BOTTOM, AT LEAST ONE SPIRAL WALL AND SEPARATE DISCHARGE CONNECTIONS FOR THE SEPARATED LIQUID AND FOR THE PURIFIED GAS. THE MIXTURE OF GAS AND LIQUID IN A QUIET UPWARDLY DIRECTED FLOW IN A PASSAGE SITUATED BETWEEN A VERTICAL SPIRAL WALL AND THE ENVELOPING WAL OF THE APPARATUS IS CONVERTED INTO A SPIRAL-FORMED HORIZONTAL FLOW, WHICH IS THEN THROTTLED INA DISCHARGE OPEINGING BETWEEN TWO SPIRAL WALLS THUS INCREASING THE FLOW VELOCITY TO A VALVE SUFFICIENT FOR CENTRIFUGAL SEPARATION OF THE LIQUID FROM THE GAS. THE FREE SPACE BETWEEN THE SPIRAL WALL OR WALLS IS DIRECTLY ABOVE THE TUBE OF LAMELLA HEAT EXCHANGER AND IS SUFFICIENTLY LARGE TO PERMIT TUBE OR LAMELLA REPLACEMENT THROUGH SAID SPACE.
