Диагностика параметров качества углей и жидких нефтепродуктов электромагнитными методами

Диагностика параметров качества углей и жидких нефтепродуктов электромагнитными методами

Abstract

Приведены результаты математического моделирования волноводного и резонаторного методов діагностики параметров качества углей и жидких нефтепродуктов (калорийности, зольности, влажности). Рассмотрен новый подход к определению волноводным методом комплексной диэлектрической проницаемости (ДП) исследуемого вещества, основанный на результатах измерения его коэффициента стоячей волны по напряжению при зондировании в некотором частотном диапазоне. Рассмотрен резонаторный метод определения ДП жидких нефтепродуктов путем размещения в трубопроводе резонаторных измерительных ячеек. Исследована возможность контроля качества углей на конвейере с использованием значений затухания электромагнитной волны, проходящей сквозь слой исследуемого угля. Результаты исследований предложено использовать для диагностики и управления качеством этих веществ, транспортируемых на конвейере или по трубопроводу.

The results of mathematical modeling of the waveguide and resonator methods for diagnosis of the parameters of quality of coal and liquid petroleum products (calorific value, ash, moisture). A new approach to defining the waveguide by the method of complex permittivity (CP) of the substance, based on the results of measuring its voltage standing wave ratio in probing the in some frequency range. Considered resonator method for determining the CP of liquid petroleum products by placing in the pipe cavity measuring cells. The possibility of controlling the quality of coal on the conveyor with the use of attenuation of electromagnetic waves passing through the layer under coal is study. The results of the research proposed to use for diagnostic and quality control of these substances to be transported on a conveyor belt or pipeline wire.
