Description
(54) УСТРОЙСТЮ ДЛЯ ИЗМЕРЕНИЯ КОНЦЕНТРАЦИИ(54) DEVICE TO MEASURE CONCENTRATION
АЭРОЗОЛЕЙAEROSOLS
Изобретение относитс к измерительной технике и может быть использовано в металлургической, энергетической , химико-технологической отрасл х промышленности.The invention relates to a measurement technique and can be used in the metallurgical, energy, chemical and technological industries.
Известно устройство дл измерени концентрации твердых частиц в газоходах , содержащее отводную трубку, внутри которой имеетс зонд, соединенный с прибором, измер ющим концентрацию частиц. В отводной трубке осуществлено движение газового потока с посто нной скоростью .A device for measuring the concentration of solid particles in ducts is known, which contains a branch tube, inside which there is a probe connected to an instrument measuring the concentration of particles. The gas flow is carried out at a constant velocity in the branch pipe.
Недостатком устройства вл етс снижение достоверности измерени за счет принудительного изменени скорости газового потока.The drawback of the device is a decrease in the measurement accuracy due to a forced change in the gas flow rate.
Наиболее близким к изобретению вл етс устройство дл измерени объемной концентрации дисперсной фазы аэрозол. , содержащее установленные в газоходе последовательно по потоку аэрозол зар дную камеру, включающую внутренний,, соединенный с вь/соковольтным модул тором, и наружный электроды, отклон ющие электроды , один из которых подключен к источнику посто нного напр жени , а другой - к шине нулевого потенциала , и индукционную измерительнуюClosest to the invention is a device for measuring the volume concentration of the dispersed aerosol phase. containing an aerosol charging chamber installed in the duct sequentially, including an internal, connected to a high voltage modulator, and external electrodes, deflecting electrodes, one of which is connected to a constant voltage source and the other to a zero voltage bus potential, and induction measuring
камеру, подключенную к преобразователю . Устройство позвол ет измер ть объемную концентрацию дисперсной фазы аэрозол .При известной плотности частиц можно получить значение массовой концентрации дисперсной фазы аэрозол { 2j.camera connected to the converter. The device allows to measure the volume concentration of the dispersed aerosol phase. With a known particle density, the mass concentration of the dispersed aerosol phase {2j can be obtained.
Недостатком устройства вл етс невозможность определени текущего The drawback of the device is the impossibility of determining the current
10 и суммарного значени массы аэрозолей вследствие того, что в них учитываетс информаци об изменении скорости потока аэрозол .10 and the total mass of the aerosols due to the fact that they take into account information on the change in the flow rate of the aerosol.
Целью изобретени вл етс расши15 рение функциональных возможностей устройства за счет измерени массы аэрозольных выбросов.The aim of the invention is to enhance the functionality of the device by measuring the mass of aerosol emissions.
Поставленна цель достигаетс тем, что в устройстве, содержащем уста- The goal is achieved by the fact that in the device containing
