Description
Изобретение относитс к способам осветлени суспензий, например микрооргаиизмов, и может иайти нримепение в микробиологической , иефт ной и химической промышленности .This invention relates to methods for clarifying suspensions, for example, microorganisms, and may find application in the microbiological, petroleum and chemical industries.
Известен способ осветлени суспензий обработкой их в емкости сто чими ультразвуковыМИ вол.нами, действующими в одном направлеи1ии , с последующим отделением образовавщегос осадка. Однако указанный способ ие обеснечивает высокой скорости осветлени .There is a known method of clarifying suspensions by treating them in a tank with standing ultrasonic waves acting in the same direction, followed by separation of the formed precipitate. However, this method does not clear the high speed of clarification.
Дл увеличени скорости осветлени предлагаетс обработку суспензии вести в кубической емкости в трех взаимно перпендикул рных направлени х сто чими ультразвуковыми волнами одинаковой частоты « 1И1Итенсивносги.To increase the rate of clarification, it is proposed to treat the suspension in a cubic tank in three mutually perpendicular directions with standing ultrasonic waves of the same frequency "1I1-Intensity".
Способ осуществл ют следующ.им обраЗОМ .The method is carried out as follows.
В кубической емкости, заиол-иенной суспензией , возбуждают поле трех взаимно перпендикул рных сто чих ультразвуковых волн одинаковой частоты н интенсивности. Частицы суспензии коагулируют в отсто щих друг от друга на половину длинны волиы сферических област х, образованных наложением взаимно перпендикул рных сто чих волн, л осаждают. Ультразвуковое поле выключают и осветленную суспензию удал ют «з емкости.In a cubic capacitance, with a suspension, they excite a field of three mutually perpendicular standing ultrasonic waves of the same frequency and intensity. The suspension particles coagulate in the spherical regions separated from each other by half the length of the will, which are formed by the imposition of mutually perpendicular standing waves, l are precipitated. The ultrasound field is turned off and the clarified suspension is removed from the container.
Устройство состоит из кубической камеры /, ультразвуковых излучателей 1-4, отражателе11 5 и 6 (трети отражатель ие показан), входного патрубка 7 дл подачи суспензии иThe device consists of a cubic chamber /, ultrasound emitters 1-4, a reflector 11 5 and 6 (the third reflector is shown), an inlet 7 for supplying the suspension and
выходного патрубка 8 дл удалени осветленной суспензии.outlet 8 to remove the clarified slurry.

The suspension is placed in a 3X3X3 cm cuvette, which is exposed to ultrasound with a frequency of 1 MHz at 10. The ultrasound field of ultrasound in the one-dimensional case is 0.6 W / cm, in the three-dimensional case 0.2 W / cm. Within 5 minutes after voicing, the transparency of the suspension is close to the maximum corresponding to the transparency of the cell-free medium.
