Description
СпбсШ теуществ етс следующим образом , t блоТГ Тп.-елени- непрерывно поступа.ют сигнальГ от датчика 4 о значении тока, протекающего через среду в межэлектродном пространстве, от датчика 5 - о значении напр жени , приложенного к рабочим электродам 2.SPb is similar to the following, t bloTG TP.-Village-continuously receive signal G from sensor 4 about the value of the current flowing through the medium in the interelectrode space, from sensor 5 about the value of the voltage applied to the working electrodes 2.
В соответствии со значени ми этих параметров блок 6 делени определ ет электропроводность среды g в межэлектродном пространстве по соотношению;In accordance with the values of these parameters, the division unit 6 determines the conductivity of the medium g in the interelectrode space by the relation;
//
иand
где / - ток, протекающий через среду вwhere / is the current flowing through the medium in
межэлектродном пространстве; и - напр жение, приложенное к рабочим электродам.interelectrode space; and - voltage applied to the working electrodes.
Сигнал о вычисленном значении электропроводности среды в межэлектродном пространстве непрерывно поступает в регул тор 7, где сравниваетс с заданным значением электропроводности среды в межэлектродном пространстве. При откло (гении от заданного значени электропроводности среды в межэлектродном пространстве регул тор 7 через магнитны усилитель 5 воздействует па источник 3 высоковольтного питани , мен папр же;,:ность электрического пол до тех пор, пока не установитс необходимое дл данной электропроводности среды в межэлектродном пространстве значение напр женности электрического пол .The signal of the calculated value of the electrical conductivity of the medium in the interelectrode space is continuously fed to the controller 7, where it is compared with the specified value of the electrical conductivity of the medium in the interelectrode space. When deviating (genius from a given value of the electrical conductivity of the medium in the interelectrode space, the regulator 7 through the magnetic amplifier 5 acts on the high-voltage power supply source 3, changing;;: the electric field until the necessary electrical conductivity of the medium is established electric field strength value.
Использование изобретени позволит повысить средний уровень рабочей напр женности электрического пол , при котором едетс процесс экстракции, а также избежать отключени высоковольтной установки при отклонени х технологических параметров за пределы, установленные технологическим регламентом.The use of the invention will allow an increase in the average level of the operating voltage of the electric field, during which the extraction process is carried out, as well as to avoid turning off the high-voltage installation with technological parameter deviations beyond the limits established by the technological regulations.
