Изобретение относитс к устройствам дл проведени процессов массообмена и может использоватьс в химической, ищевой и других родстбённых отрас х промышленности, в. частности дл абсорбции с1ммиака из газов дистилл ии в производстве аммиачной селитры. Известна контактна тарелка, содераща контактный элемент с завихрителем и переливные устройства 1П. Наиболее близким по технической сущности к предлагаемому вл етс устройство, содержащее контактный элемент, выполненный в виде усеченных конусов, соединенных большими основани ми и с завихрителем в верхней части, выполненным в виде секторных элементов (2).The invention relates to devices for carrying out mass transfer processes and can be used in chemical, searching and other related industries, c. in particular for the absorption of carbon monoxide from distillation gases in the production of ammonium nitrate. Known contact plate, containing the contact element with a swirl and overflow device 1P. The closest in technical essence to the present invention is a device comprising a contact element made in the form of truncated cones connected by large bases and with a swirler in the upper part made in the form of sector elements (2).
Недостатком этого устройства вл етс недостаточно высока интенсивность массообмена, поскольку больша часть жидкости, мину контактный элемент, проходит через гидрозатвор и стекает,пленкой вниз, т.е. основное взаимодействие газа и жидкости происходит в пленочнсж режиме. Иэвестно , что при диспергировании потока жидкости быстродвижущимс потоком газа интенсивность процессов тепло и мйссообмена в несколько раз выше.A disadvantage of this device is that the mass transfer rate is not high enough, since most of the liquid, the contact element, passes through the water seal and flows down, i.e. the main interaction of gas and liquid occurs in film mode. It is known that when a fluid flow is dispersed by a fast-moving gas flow, the intensity of the processes of heat and mass exchange is several times higher.
чем при турбулизации пленки жидкости газовым потоком.than with the turbulence of a liquid film by gas flow.
К недостаткам этого устройства следует отнести и неспособность конструкции эффективно работать при больших плотност х орошени . При увеличении количества жидкой фазы требуетс увеличить зазор между стенкой аппарата и контактным элементом ДИ9Я пропуска ее. Однако это приводит к увеличению толщины пленки и резкому снижению эффективности массообмена. .The disadvantages of this device include the inability of the structure to work effectively with high irrigation densities. With an increase in the amount of the liquid phase, it is required to increase the gap between the wall of the apparatus and the contact element DI9Ya of its passage. However, this leads to an increase in the film thickness and a sharp decrease in the efficiency of mass transfer. .
Цель изобретени - увеличение плотности орошени и интенсификацииThe purpose of the invention is to increase the density of irrigation and intensification
процесса массотеплообмена за счет увеличени времени, зон и поверхности контакта фаз.the process of mass transfer by increasing the time, zones and surface contact of the phases.
