EXTERNAL STATIC CROSS SPARGERS TO PROVIDE FINE AND UNIFORM BUBBLES FOR BUBBLE COLUMN DEVICE

摘要

The invention relates to a bubble column device to generate ultrafine and uniformly dispersable particles of inmiscible fluid having continuous and discontinuous phases, comprising at least two external Sparger devices, wherein the first sparger device consisting of at least one static three cross sparger having a static element comprising three plates to form at least two x-cross bars opposedly disposed at an angle of 90° with respect to the axial direction, and wherein the second sparger device consists of at least one static six cross sparger having six plates to form at least three X-cross bars; a centrifugal pump to control flow of water through the water inlet of the spargers, and acting as a continuous fluid; a source to supply air inside the bubble column device to act as dispersed fluid elements; an air rotameter to measure the air inlet into the column device through the air inlets of the spargers; and a pressure transducer to calculate the gas hold-up inside the bubble column, wherein the spargers are disposed vertically at the bottom of the bubble column to operate against the gravity forces acting upward or downward direction of the main flow, and wherein the second sparger device is rotatably disposed at 90° with respect to the axial direction.
