Description
Изобретение относитс к контролю качества пека и к производству каменноугольного высокоплав кого пека, используемого дл получени пекового кокса.This invention relates to quality control of pitch and to the production of high-melting coal tar pitch used to produce pitch coke.
Известен способ определени выхода летучих веществ дл каменноугольного пека по его качеству, путем замера потерь в весе навески пека после ее нагрева в муфельной печи . Однако он не обеспечивает непрерывный контроль качества нека в потоке.There is a known method for determining the yield of volatile substances for coal tar pitch by its quality, by measuring the loss in weight of the weight of the pitch after it is heated in a muffle furnace. However, it does not provide continuous quality control in the stream.
Предлагаемый способ отличаетс тем, ч го измер ют в потоке плотность пека, нркведеиную посредством термокомпенсации к посто нной температуре. Это автоматизирует контроль .The proposed method is distinguished by the fact that the density of the pitch is measured in flow, which is conveyed by means of thermal compensation to a constant temperature. This automates the control.
Па чертеже представлена схема устройства дл реализации способа.Pa the drawing shows a diagram of the device for implementing the method.
Устройство содержит сосуд /, дросселирующий стакан 2, снабженный буйком 3, вторичный прибор 4, блок 5 термокомпенсации, термопару 6, вторичный прибор 7 и прибор 8.The device contains a vessel /, throttling glass 2, equipped with a buoy 3, a secondary device 4, a block of thermal compensation 5, a thermocouple 6, a secondary device 7 and the device 8.
Каменноугольный пек непрерывно протекает через сосуд и дросселирующий стакан. С помощью вторичного прибора 4 измер етс Coal pitch continuously flows through the vessel and the throttling cup. With the aid of the secondary device 4,
плотность пека, завис ща от его качества и температуры нагрева. Дл устранени вли ни скорости потока на измерение плотности сосуд в рабочей части расщирен, а буек помещен в дросселирующем стакане. Со вторичного прибора 4 сигнал, пропорциональный плотности пека, поступает в блок термокомьепсации , куда также поступает сигнал, пропорциоиальиый изменени м плотности пека от температуры его нагрева, котора замер етс термопарой . С блока сигнал, пропорциональный плотности пека, поступает в прибор 8, щкала которого проградуирована в процентах выхода летучих веществ по предварительно определенной зависимости между выходом летучпх веществ и плотностью пека.pitch density, depending on its quality and heating temperature. To eliminate the influence of the flow velocity on the density measurement, the vessel in the working section is expanded and the displacer is placed in the throttling cup. From the secondary device 4, a signal proportional to the density of the pitch enters the thermocompelling unit, which also receives a signal proportional to changes in the density of the pitch from its heating temperature, which is measured by a thermocouple. From the block, a signal proportional to the density of the pitch enters the device 8, the scale of which is graduated in percent of the volatile matter yield according to a predetermined relationship between the volatile matter yield and the pitch density.
