Изобретение относитс к устройствам дл смешени нефти с водой при ее обессо- ливании и может быть использовано в нефт ной , нефтехимической,химической и других отрасл х промышленности.The invention relates to devices for mixing oil with water during its desalting and can be used in the petroleum, petrochemical, chemical and other industries.
Целью изобретени вл етс повышение эффективности процесса за счет регулировани степени дисперсности эмульсии.The aim of the invention is to increase the efficiency of the process by controlling the degree of dispersion of the emulsion.
Да фиг.1 представлено смесительное устройство установки обессоливанм нефти , общий вид; на фиг.2 - сечение А-А на фиг.1.Yes figure 1 presents the mixing device installation desalting oil, a general view; figure 2 - section aa in figure 1.
Смесительное устройство установки обессоливани нефти содержит последовательно соединенные входной патрубок 1, конфузор 2, проставку 3, в которой закреплен , например, тангенциальный патрубок ввода воды 4, диффузор 5, дополнительную проставку 6, дополнительный диффузор 7 и выходной патрубок 8. Входной патрубок 1 соединен с дополнительной проставкой 6 байпасной линией 9 с регулирующим органом 10.The oil desalting device has a mixing device that contains inlet pipe 1, a confuser 2, a spacer 3, in which, for example, a tangential water inlet 4, a diffuser 5, an additional spacer 6, an additional diffuser 7 and an outlet 8 are fixed. The inlet 1 is connected to additional spacer 6 bypass line 9 with the regulatory authority 10.
Проставка 3 представл ет собой первую ступень смешивани , а дополнительна проставка 6 - вторую ступень смешивани .Spacer 3 is the first mixing stage, and additional spacer 6 is the second mixing stage.
Смесительное устройство установки обессоливани нефти работает следующим образом.The mixing device of the oil desalting plant operates as follows.
Поток нефти в патрубке 1 раздел етс на два потока, один из которых поступает на первую ступень проставки 3 в зону диспергировани смесительного устройства, а второй через байпасную линию 9 поступает на вторую ступень (проставку 6) в зону смешени . Одновременно в зону диспергировани тангенциально вводитс через патрубок 3 поток воды.The oil flow in nozzle 1 is divided into two streams, one of which enters the first stage of the spacer 3 into the dispersing zone of the mixing device, and the second through the bypass line 9 enters the second stage (spacer 6) into the mixing zone. At the same time, a stream of water is introduced tangentially into the dispersion zone through the pipe 3.
Скорости потоквв воды и нефти различны по направлению и абсолютной величине, что вызывает их интенсивное взаимодействие между собой с образованием эмульсии нефть-вода (Н-В). При этом скорость ввода воды больше скорости движени нефти, чтоThe flow rates of water and oil are different in direction and absolute value, which causes their intense interaction with each other to form an oil-water emulsion (HB). At the same time, the rate of water input is greater than the speed of oil movement, which
вызывает вращательное движение системы Н-В в направлении, определ емом направлением ввода воды. На внутренней поверхности зоны диспергировани образуетс causes rotational movement of the HB system in the direction determined by the direction of water input. On the inner surface of the dispersion zone is formed
тонка пленка воды, котора посто нно испытывает воздействие потока нефти, диспергируетс в ней с образованием мелких однородных капель. Известно, что капли воды имеют определенный критический диаметр , определ емый турбулентностью потока, в котором происходит диспергирование . Следовательно, вращательное движение жидкостей способствует большему диспергированию воды в нефти.a thin film of water, which is constantly affected by the flow of oil, is dispersed in it to form small, uniform droplets. It is known that water droplets have a certain critical diameter, determined by the turbulence of the flow in which dispersion occurs. Consequently, the rotational movement of liquids contributes to a greater dispersion of water in the oil.
На выходе из зоны диспергировани поток эмульсии имеет форму конуса, расшир ющегос по ходу движени потока, Этот поток смешиваетс с оставшейс частью нефти, поступающей в зону смешени поAt the outlet of the dispersion zone, the emulsion flow is in the form of a cone expanding along the flow of the stream. This flow is mixed with the remaining part of the oil entering the mixing zone in
байпасной линии 9. Степень диспергировани воды на однородные мелкие капли в потоке нефти достигают за счет большего или меньшего открыти байпасной линии, что способствует образованию монодисперсной эмульсии и способствует, в конечном счете, более эффективному процессу обессоливани нефти на установках обессоливани .bypass line 9. The degree of dispersion of water into homogeneous fine droplets in the oil flow is achieved by opening the bypass line more or less, which contributes to the formation of a monodisperse emulsion and contributes, ultimately, to a more efficient desalting process for oil desalting plants.
