Description
Известны электрические газовые анализаторы, состо щие из двух камер рабочей и сравнительной.Electric gas analyzers are known which consist of two working and comparative chambers.
Предлагаемый газоанализатор в отличие от известных имеет, кроме рабочей и сравнительной, еще и мерную цилиндрическую камеру, котора может вращатьс вокруг своей оси и попеременно соедин тьс либо с рабочей камерой, либо с продувочными трубками. Через продувочные трубки осуществл етс продувка мерной камеры и заполнение ее свежей анализируемой смесью. Такое выполнение прибора позвол ет использовать его как в качестве газоанализатора, так и в качестве газового калориметра.The proposed gas analyzer, in contrast to the known ones, has, in addition to the working and comparative, also a measuring cylindrical chamber, which can rotate around its axis and alternately connect either with the working chamber or with the purge tubes. Through the purge tubes, the metering chamber is purged and filled with fresh analyte mixture. Such an embodiment of the device allows using it both as a gas analyzer and as a gas calorimeter.
На фиг. 1 показан описываемый газоанализатор (в разрезе); на фиг. 2 - его электрическа схема.FIG. 1 shows the described gas analyzer (in section); in fig. 2 - his electrical circuit.
Прибор имеет три камеры - рабочую /, сравнительную 2 и мерную 5, котора продуваетс и заполн етс калориметрируемой смесью через трубки 4. В рабочей и сравнительной камерах смонтированы равные по сопротивлению платиновые нити, нагреваемые электрическим током.The device has three chambers - working /, comparative 2 and measuring 5, which is blown and filled with the calorimetric mixture through tubes 4. In the working and comparative chambers, equal in resistance platinum filaments heated by electric current are mounted.
Электрическа схема газоанализатора (фиг. 2) представл ет собой неравновесный мост, в диагональ которого включен чувствительный милливольтметр mV. Плечами моста служат посто нные сопротивлени 1 и и сопротивлени платиновых нитей:/ з сопротивление нити, наход щейс в рабочей камере, а сравнительной. Переменное сопротивление служит дл установки нул милливольтметра. Питание прибора электрическим током производитс от аккумул торной батареи Б через амперметр А и реостат регулировки тока накала платиновых нитей.The electrical circuit of the gas analyzer (Fig. 2) is a non-equilibrium bridge, the diagonal of which includes a sensitive mV mV. The shoulders of the bridge are the constant resistances 1 and and the resistances of the platinum filaments: / C the resistance of the filament located in the working chamber, and the comparative one. Variable resistance is used to set the zero millivoltmeter. The device is powered by an electric current from battery B via an ammeter A and a rheostat for adjusting the current of platinum filaments.
Температурный (тепловой) эффект полного сжигани анализируемой газовой смеси, & следовательно, и калорийность ее определ етс по показани м милливольтметра mV (но плои1ади полученной диаграммы).Temperature (heat) effect of complete combustion of the analyzed gas mixture, & consequently, its calorific value is also determined by the readings of the mV voltmeter (but the value of the diagram obtained).
Описанный газоанализатор может быть применен дл калориметрировани смесей, имеющих калорийность от 1 до 100 ккал/нм. Более калорийные газовые смеси следует разбавл ть воздухом. ЧувствительThe described gas analyzer can be used to calorimetrate mixtures having a calorific value of from 1 to 100 kcal / nm. More high-calorie gas mixtures should be diluted with air. Sensory
