Изобретение относитс к области физикохимического анализа.This invention relates to the field of physicochemical analysis.
Известны способы определени сухости пара, заключающиес в том, что из основного потока отбирают часть пара и конденсируют его, а полученный конденсат дел т на две части (пр мой поток и обратный), одну из которых пропускают через дроссель, испар ют и перегревают за счет тепла, выдел ющегос при конденсации пара, а затем перегретый пар направл ют в теплообменник дл теплообмена с другой частью конденсата и по измеренным перепадам температур определ ют отношение расходов обеих частей, а искомый параметр вычисл ют.Methods are known for determining steam dryness, consisting in that a part of steam is taken from the main stream and condensed, and the resulting condensate is divided into two parts (forward and reverse), one of which is passed through the throttle, evaporated and overheated due to the heat released during condensation of the steam, and then the superheated steam is sent to the heat exchanger for heat exchange with the other part of the condensate, and a ratio of the flow rates of both parts is determined from the measured temperature differences, and the desired parameter is calculated.
Недостатком известных спо собов вл етс периодичность и сложность определени сухости пара.A disadvantage of the known methods is the frequency and complexity of determining the dryness of steam.
Цель изобретени - обеспечить непрерывность и простоту определени сухости пара.The purpose of the invention is to ensure the continuity and simplicity of determining the dryness of steam.
Эта цель достигаетс тем, что по предлагаемому способу пар перед конденсацией пропускают через калиброванное отверстие, на котором поддерживают посто нный перепад давлени , конденсацию пара осуществл ют при смешивании его с водой а после конденсации измер ют расход конденсата с водой. По величине разности расходов конденсата с водой и воды определ ют расход конденсата пара, характеризующий сухость пара.This goal is achieved in that the proposed method passes steam before condensation through a calibrated orifice at which a constant pressure drop is maintained, the steam condensation is carried out by mixing it with water, and after condensation the flow rate of the condensate with water is measured. The consumption of steam condensate, which characterizes the dryness of steam, is determined from the magnitude of the difference in consumption of condensate with water and water.
На чертеже показано устройство, осуществл ющее описываемый способ.The drawing shows the device implementing the described method.
Устройство работает следующим образом.The device works as follows.
Часть пара от магистрального паропровода по трубопроводу 1 проходит через калиброванное отверстие 1, перепад на котором поддерживаетс регул тором посто нного перепада 3 и далее поступает в смеситель 4. По трубопроводу 5 через измеритель расхода 6 в смеситель 4 поступает вода. Пар после кондепсации при смешении с водой по трубопроводу 7 уходит на слив. Общий расход конденсата с водой замер етс измерителем расхода 8.Part of the steam from the main steam line passes through the pipeline 1 through the calibrated orifice 1, the differential on which is maintained by the constant differential controller 3 and then enters the mixer 4. Water through the pipeline 5 through the flow meter 6 to the mixer 4. Steam after kondepsatsii when mixed with water through the pipeline 7 goes to the drain. The total consumption of condensate with water is measured by a flow meter 8.
По разности расхода конденсата с водой и воды суд т о степени сухости измер емого пара, так как сухость пара пропорциональна квадрату расхода пара через калиброванное отверстие 1.The difference in condensate consumption with water and water determines the degree of dryness of the measured steam, since the dryness of steam is proportional to the square of the consumption of steam through the calibrated orifice 1.
