Description
Изобретение относится к микробиологической промышленности.The invention relates to the microbiological industry.
Пр основному авт. св. № 305184 известен способ обработки микроорганизмов электрическим полем в жидкой среде путем пропускания жидкости по оси цилиндрического электрода и создания электрического поля между цилиндрическим полем и жидкостью [1 ].Pr main auth. St. No. 305184, a method is known for treating microorganisms with an electric field in a liquid medium by passing liquid along the axis of a cylindrical electrode and creating an electric field between the cylindrical field and the liquid [1].
Однако этот способ не обеспечивает высокой точности, так как возможны колебания й отклонения струи жидкости под действием электрических сил и замыкания струи жидкости на цилиндрический электрод.However, this method does not provide high accuracy, since fluctuations of the deflection of the liquid jet under the action of electric forces and shorting of the liquid jet to the cylindrical electrode are possible.
Цель изобретения - повышение точности способа.The purpose of the invention is to improve the accuracy of the method.
Указанная цель достигается тем, что в способе обработки микроорганизмов электрическим полем в жидкой среде по основному авт. св,. № 305184 на струю жидкости подают переменное электрическое напряжение.This goal is achieved by the fact that in the method of processing microorganisms by an electric field in a liquid medium according to the main author. St. No. 305184 an alternating voltage is applied to the liquid stream.
При этом частота переменного элект-25 рического напряжения равна 10 5 105 Гц.The frequency of alternating electric voltage is 10 5 10 5 Hz.
На чертеже показана схема устройства для осуществления предлагаемого способа. 30The drawing shows a diagram of a device for implementing the proposed method. thirty
Способ осуществляется следующим образом.The method is as follows.
Жидкость с микроорганизмами, наj пример питательной средой, которая является электропроводящей, подают струей по оси внешнего цилиндрического электрода 1 из бака 2 в бак 3.A liquid with microorganisms, for example, a nutrient medium that is electrically conductive, is supplied with a stream along the axis of the outer cylindrical electrode 1 from the tank 2 to the tank 3.
Переменное электрическое напря10 жение частотой 10’ - 105 Гц подают, от источника напряжения 4 на цилиндрический электрод 1 и струю, которая служит внутренним цилиндрическим электродом.An alternating electric voltage with a frequency of 10 '- 10 5 Hz is supplied from a voltage source 4 to a cylindrical electrode 1 and a stream, which serves as an internal cylindrical electrode.
Между струей жидкости и внешним 15 электродом 1 создается резко неравномерное переменное электрическое поле. В зоне струи при этом концентрируется практически воя электроэнер гия и создается максимальная нап20 ряженность электрического поля Е струи, которая вычисляется по формуΠβ Е .—ML сСТГ9И 23rejrR/r где г - радиус с^труи)Between the liquid stream and the external 15 electrode 1, a sharply non-uniform alternating electric field is created. In this case, practically total electric energy is concentrated in the jet zone and a maximum electric field strength E of the jet is created, which is calculated by the shape of Πβ E. - ML with STG9I 23rejrR / r where r is the radius of the squad)
R - радиус внешнего цилиндрическог® электрода)R is the radius of the outer cylindrical® electrode)
U · - приложенное электрическое напряжение.U · is the applied electrical voltage.
В результате возникновения между струей жидкости и внешним цилиндрическим электродом переменного электрического поля на струю действуют электрические силы, изменяющие направление своего действия с частотой 10 - 105 Гц. Струя жидкости благодаря действию сил инерции не успевает изменить направление своего движения по оси внешнего электрода, че колеблется и не замыкается на внешний электрод.As a result of the occurrence of an alternating electric field between the liquid stream and the external cylindrical electrode, electric forces act on the stream, changing their direction of action with a frequency of 10 - 10 5 Hz. Due to the action of inertia forces, the liquid stream does not have time to change the direction of its movement along the axis of the external electrode, but it oscillates and does not close to the external electrode.
Во время движения жидкости в зоне действия электрического поля происходит обработка микроорганизмов, находящихся в струе жидкости.During the movement of the liquid in the zone of action of the electric field, the processing of microorganisms in the liquid stream occurs.
Применение предлагаемого способа позволяет значительно повысить надежность, точность и эффективность об работки жидкостей электрическими полями.The application of the proposed method can significantly increase the reliability, accuracy and efficiency of the treatment of liquids by electric fields.
