Gas-liquid guiding column plate

Abstract

The invention relates to a gas-liquid guiding column plate which is provided with a guide hole, guide weirs, turbulence intensifiers and a down-flow plate, wherein the guide hole in the column plate is a bump punched on the column plate, one edge, directly connected with the column plate, of the guide hole is vertical to the horizontal direction of the column plate while the other edge of the guide hole forms an included angle ranging from -30 degrees to 30 degrees with the horizontal direction of the column plate; the guide weirs on the column plate are a series of baffles vertical to the column plate, the height of each guide weir reaches or exceeds that of a bottom gap, and the width among the guide weirs is related to the strength of a liquid flow; the turbulence intensifier is arranged at the liquid phase inlet of each column plate, and each turbulence intensifier is an abnormal barrier integrally connected with the column plate; the down-flow plate on the column plate is a folded-line down-flow plate, so that a hole opening area and a gas-liquid transfer area are increased, and the liquid seal height of the down-flow pipe is increased. The column plate is high in mass transfer efficiency, great in production capacity, novel in structure and low in manufacturing cost, and can be widely applied to separating industries such as chemical engineering industry, oil refining industry, food industry, light industry and environmental industry.

Problems solved by technology

At the same time, further studies have found that in the rectangular main flow area between the two weirs, the liquid velocity distribution is not uniform, and the liquid flow in the arcuate area is divided into a slow flow area and a regurgitation area. This uneven flow of liquid seriously affects the Plate efficiency

[0005] It is the characteristic of the downcomer to provide a medium for the transfer of the liquid phase between the trays. If the liquid phase load is too large, it will easily cause the liquid phase in the downcomer to block, prevent the normal flow of the liquid, and cause the tray to flood, that is, the tower is flooded. If the phase load is too low, the liquid seal height of the downcomer will be inappropriate, and the gas will directly escape from the downcomer, affecting the normal flow of the liquid phase
