(54) ВИХРЕВАЯ ТЕПЛОМАССООБМЕННАЯ КОЛОННА(54) VORTEX HEAT AND MASS-EXCHANGE COLUMN

1one

Пр длагаемое изобретение относитс к массообмениой; аппаратуре и может быть использовано в массообменной колонне, примеи емой как абсорбер) ректификатор и т. дThe present invention relates to mass transfer; equipment and can be used in a mass transfer column, used as an absorber, rectifier, etc.

Известна контактна тарелка, включающа контактные патрубки и турбулизирующие устройства, выполненные в виде стакана с таигеноиальнымн t прорез ми, расположенными над плоскостью тарелки и соосно с контактным патрубком 1.A known contact plate includes contact nozzles and turbulizing devices made in the form of a cup with taigenoi t slots located above the plane of the plate and coaxially with the contact nozzle 1.

Известна тепломассообменна колонна, содержаща корпус, расположенные внутри него переливные устройства и контактные элементы закрепленные в разделительных перегородках и днищах, состо щие из пат рубков с отверсти ми дл подачи в них жидкости , завихрителей и каплеуловителей 21,A known heat and mass transfer column, comprising a housing, overflow devices located inside it and contact elements mounted in the dividing walls and bottoms, consisting of strings with openings for supplying them with liquid, swirlers and droplet separators 21,

Серьезным недостатком ; сзгаествующих вихревых тарелок вл етс значительный каплеунос, снижающий эффективность контактного массообменного аппарата..Serious disadvantage; Swirling vortex plates is a significant kapleunos, reducing the effectiveness of the contact mass transfer apparatus ..

Цель предлагаемого устройства - уменьшение кшлеуноса, увеличение интенсивности массобмена.The purpose of the proposed device is to reduce shleunosa, increasing the intensity of mass transfer.

С этой целью каждый контактный элемент снабжен газопроводом, нижний конец которого соединен с патрубком и расположен ниже его отверстий, а верхний конец расположен по оси контактного элемента напротив зави фител .For this purpose, each contact element is provided with a gas pipeline, the lower end of which is connected to the branch pipe and is located below its openings, and the upper end is located along the axis of the contact element opposite to the dependence of the pipe.

Целесообразно верхний конец газопровода снабжать завихрителем.It is advisable to supply the upper end of the pipeline with a swirler.

На чертеже приведена; конструкци предлагаемой вихревой тепломассообменной койонны .The drawing is; the design of the proposed vortex heat-mass exchange koyonne.

Колонна состоит из корпуса 1 переливных устройств 2, контактных элементов, содержащих входные патрубки 3 с отверсти ми 4, лопаточный завихритель 5 и каплеуловитель 6, каждый контакт р 1й элемб.гг содержит газопровод 7, на верхнем конце которого установлен завихритель 8, нижний КО1ЮЦ газопровода расположен ниже отверстий 4. Контактные элементы закреп;лены в разделительной перетх)родке 9 и днище 1О, которые соединены-между собой переливными каналами 11.The column consists of a housing 1 overflow device 2, contact elements containing inlet nozzles 3 with holes 4, paddle swirler 5 and droplet separator 6, each contact p 1st unit contains gas pipeline 7, at the upper end of which is installed a swirler 8, lower KO1JT gas pipeline It is located below the holes 4. The contact elements are fastened; they are located in the separator section 9 and the bottom 1O, which are interconnected by means of overflow channels 11.

Claims

Works vortex heat and mass transfer column in a blinding way. The gas (vapor) enters the inlet nozzles 3, where the worm hole 4 is drunk a liquid, which is postutgated on the double U through the overflow device 2 from the upper element. The gas (vapor) flow of the liquid is crushed and carried away to the scooper 5. On the evacuator 5 there is a film of liquid, which, again crushed by the gas (vapor) stream, again the droplets of the liquid enter the film as the swirler channels are curvilinear. The described process takes place intensively and ensures good contact between the mass and liquid between the liquid and the gas (steam). After the swirler, the dispersion 5 flow in the drip catcher. A liquid cap is pumped with cantropeagous forces into the wall of the drip catcher and, as a captive, flows into the separator 9. as the main flow, and moves towards the main flow. The small droplets of liquid remaining in the central area of the column fall into this stream and are thrown out to the periphery. Besides, since the gas of the swirling jet has not previously come into contact with the liquid, there is an intense additional mass exchange of gas with the liquid, since in this case the linear velocity between the phases and the surface of the contact of the phases are also great, the liquid flows through the transfer channel 11 at the bottom 10 of the next contact element for further participation in mass transfer. The formula of the invention 1. Vortex heat and mass transfer column. containing a body, overflow devices located inside it and contact elements fixed in partitions and bottoms, consisting of strings with openings for supplying fluid in them, swirlers and a drop catcher, which, with the aim, reduce dropleunos and increase intustivism mass transfer, each contact element is provided with a gas pipeline, and its end is connected to the nozzle and located below its openings, and the upper shaft is located along the axis of the contact element opposite the swirler. 2. A column according to claim. 1, characterized by. Scha and with the fact that the upper end of the pipeline is equipped with a swirl. Sources of information received during the examination: 1.
