Abstract

FIELD: mass exchange column structure, interaction of gas (vapor)/fluid systems intended for gas absorption, rectification, washing, may be applied in chemical, oil-chemical, gas industries. SUBSTANCE: jet plate includes horizontal slab of circular cross section installed over another similar slab in vertical cylindrical column with central vertical vapor pipe. A cap is installed coaxially over the central pipe. Perforations are originated in lower part of cap lateral walls. Dump pipe is installed over the slab. Overflow pipe is built tightly in plate slab. Upper edge of the pipe is placed over the perforation in lateral walls of the cap. Semi-circular vapor pipe is installed coaxially around central vapor pipe. Semi-circular vapor cap with perforation in lower part of lateral walls is installed over the vapor pipe. Additional horizontal perforated slab is installed over plate slab between central and semi-circular caps. The slab is closely attached to lower edges of central and semi-circular caps. Lower edge of dump pipe is spaced from additional slab at a distance equal to one forth of dump pipe internal diameter. Dump pipe is placed between central cap and edge of semi-circular cap. Overflow pipe is placed between column wall and another edge of semi-circular cap. Vertical partition is installed over additional slab. The partition passes diametrically over central cap and over external perimeter of semi-circular cap up to its edge where it is attached to column wall. Partition height is equal to spacing between plates over column height. Perforation in additional slab are originated in the form of arched slots with convex up with axes coming from dump pipe towards overflow pipe along passage between lateral walls of central and semi-circular caps. Perforation openings in lateral walls of the central and semi-circular caps are originated in the form of arched slots with convex outwards with axes inclined at acute angle to vertical line bottom and towards the same side coincided with direction of axes of arch slots in additional slab. Positions of dump and overflow pipes are exchanged at upper and lower plates as for position at the given plate. Arch slots in additional slabs and in lateral walls of caps are directed aside in adjacent plates. Apart from above diametral partition over the cap, and perforation in the form of arched slots with convex up on plate slab are available. EFFECT: improved mass exchange between gas (vapor) and fluid at the expense of increased time when fluid is in contact with gas (vapor).

Изобретение относится к конструкциям массообменных колонн для взаимодействия систем газ(пар)-жидкость, предназначенных для процессов абсорбции, ректификации, промывки газов и может найти применение в химической, нефтехимической, газовой и в других смежных отраслях промышленности. Цель изобретения - повышение эффективности массообмена между газом (паром) и жидкостью за счет увеличения времени пребывания жидкости в контакте с газом (паром). Цель достигается тем, что струйная тарелка, включающая горизонтальную плиту круглого сечения, установленную одна под другой в вертикальной цилиндрической колонне с центральным вертикальным паровым патрубком, над центральным патрубком осесимметрично установлен колпачок, в нижней части боковых стенок которого выполнены перфорации, над плитой установлена сливная труба, в плиту тарелки плотно вставлена переливная труба, верхняя кромка которой расположена выше перфорации в боковых стенках колпачка, вокруг центрального парового патрубка осесимметрично установлен полукольцевой паровой патрубок, над которым установлен полукольцевой паровой колпачок с перфорациями в нижней части боковых стенок, над плитой тарелки между центральным и полукольцевым колпачками установлена горизонтальная дополнительная перфорированная плита, плотно прикрепленная к нижним кромкам центрального и полукольцевого колпачков, с отверстием для переливной трубы, нижняя кромка сливной трубы отстоит от дополнительной плиты на расстоянии, равном одной четверти внутреннего диаметра сливной трубы, сливная труба расположена между центральным колпачком и краем полукольцевого колпачка, а переливная труба расположена между стенкой колонны и другим краем полукольцевого колпачка, над дополнительной плитой плотно установлена вертикальная перегородка, проходящая диаметрально над центральным колпачком и над наружным периметром полукольцевого колпачка до его края, где примыкает к стенке колонны, высота перегородки равна расстоянию между тарелками по высоте колонны, перфорации и дополнительной плите ленными от сливной трубы в направлении к переливной трубе по каналу между боковыми стенками центрального и полукольцевого колпачков, перфорации в боковых стенках центрального и полукольцевого колпачков выполнены в виде арочных прорезей выпуклостью наружу с направлением осей под острым углом к вертикали вниз и в одну и ту же сторону, совпадающую с направлением осей арочных прорезей в дополнительней плите, на нижерасположенной и высокорасположенной тарелках сливные и переливные трубы взаимно меняются местами по сравнению с данной тарелкой, направления арочных прорезей в дополнительных плитах и в боковых стенках колпачков на смежных по высоте тарелках противоположное. Новым в заявляемом изобретении является наличие диаметральной перегородки над колпачком и перфораций в виде арочных прорезей выпуклостью вверх на плите тарелки с осями, направленными тангенциально от сливной к переливной трубе и арочных прорезей в нижних кромках колпачка выпуклостью наружу и под острым углом к вертикали в сторону переливной трубы.The invention relates to the construction of mass transfer columns for the interaction of gas (steam) -liquid systems intended for the processes of absorption, rectification, gas flushing and can find application in chemical, petrochemical, gas and other related industries. The purpose of the invention is to increase the efficiency of mass transfer between gas (vapor) and liquid by increasing the residence time of the liquid in contact with the gas (steam). The goal is achieved by the fact that the jet plate, including a horizontal plate of circular cross section, mounted one below the other in a vertical cylindrical column with a central vertical steam pipe, a cap is axially symmetrically mounted above the central pipe, perforations are made in the lower part of the side walls, a drain pipe is installed over the plate, an overflow pipe is tightly inserted into the plate plate, the upper edge of which is located above the perforation in the side walls of the cap, around the central steam pipe an axially symmetric semi-annular steam nozzle is installed, over which a semi-annular steam cap with perforations in the lower part of the side walls is installed, a horizontal additional perforated plate, tightly attached to the lower edges of the central and semi-annular caps, with an overflow hole, is installed between the central and semi-annular caps above the plate of the plate the lower edge of the drain pipe is separated from the additional plate by a distance equal to one quarter of the inner diameter of the drain pipe, a drain pipe is located between the central cap and the edge of the semicircular cap, and an overflow pipe is located between the column wall and the other edge of the semicircular cap, a vertical partition is tightly mounted above the additional plate, passing diametrically above the central cap and over the outer perimeter of the semicircular cap to its edge, where it adjoins the wall of the column, the height of the partition is equal to the distance between the plates along the height of the column, perforation and an additional plate from the drain pipe in the direction the overflow pipe along the channel between the side walls of the central and semicircular caps, the perforations in the side walls of the central and semicircular caps are made in the form of arched slots convex outward with the axes pointing at an acute angle to the vertical down and in the same direction, coinciding with the direction of the axes arched slots in the additional plate, on the lower and high located plates, the drain and overflow pipes mutually change their places compared to this plate, the direction of the arched slots additional plates and the side walls of caps on adjacent plates opposite height. New in the claimed invention is the presence of a diametrical partition above the cap and perforations in the form of arched slots convex upward on the plate of the plate with axes tangentially directed from the drain to the overflow pipe and arched slots in the lower edges of the cap with the convexity outward and at an acute angle to the vertical towards the overflow pipe .
