Abstract
Изобретение относитс к области теплоэнергетики и может быть применено дл очистки конденсаторов паровых турбин электростанций. Цель изобретени - повьшение качества очистки . Способ предусматривает подачу на очищаемую поверхность газожидкостной среды в пузьфьковом режиме течени и формирование в ней, например, посредством электрических разр дов импульсов давлени с частотой, равной собственной частоте колебаний газовых пузырей в газожидкостной среде . 1 з.п. ф-лы, 1 ил. ро оо о NU 4 The invention relates to the field of heat and power engineering and can be applied to the cleaning of steam turbine condensers of power plants. The purpose of the invention is to improve the quality of cleaning. The method involves supplying the gas-liquid medium to the surface being cleaned in the puffy flow mode and forming in it, for example, by means of electrical discharges of pressure pulses with a frequency equal to the natural frequency of vibrations of gas bubbles in the gas-liquid medium. 1 hp f-ly, 1 ill. ro oo o nu 4

Изобретение относитс к тепло- энергетике и может быть использовано дл очистки конденсат.оров паровых турбин электростанций.The invention relates to heat and power engineering and can be used for cleaning condensate of steam turbines of power plants.
Цель изобретени - повышение качества очистки.The purpose of the invention is to improve the quality of cleaning.
На чертеже изображено устройство дл осуществлени предлагаемого способа .The drawing shows a device for carrying out the proposed method.
Устройство содержит систему очистки конденсатора 1, включающую напорн водовод 2, магистраль 3 сжатого воздуха с воздухораздающим устройствомThe device contains a system for cleaning the condenser 1, which includes a discharge conduit 2, a line 3 of compressed air with an air-distributing device
4,формирун цим газовые пузырьки 5, и электрокмпульсное устройство 6.4, forming gas bubbles 5, and an electro-pulse device 6.
Способ осуществл ют следующим образом .The method is carried out as follows.
При циркул ции охлаждающей воды, подаваемой в конденсатор 1, осуществл ют подвод сжатого воздуха под давлением, превышающим давление в напорном водоводе трубопроводу. Воздух равномерно раздаетс в объем потока охлаждающей воды. Исключение агломерации и сепарации газовой фазы осуществл етс за счет повьш ени скорости двухкомпонентного потока в входной камере в направлении трубок конденсатора над скоростью пузырьковWhen circulating cooling water supplied to condenser 1, compressed air is supplied under a pressure exceeding the pressure in the pressure conduit of the pipeline. Air is evenly distributed into the cooling water flow. Elimination of agglomeration and separation of the gas phase is carried out by increasing the velocity of the two-component flow in the inlet chamber in the direction of the condenser tubes above the velocity of the bubbles.
5,определ емой их размерами. При помощи электроимпульсного устройства 6 в дзухкомпонентном потоке формируют импульсы давлени частотой, совпадаюЕЭ-15, determined by their size. Using an electric pulse device 6 in a dual component stream, pressure pulses are generated with a frequency that coincides with EE-1.

газовых пузырей. Возникающие при резонансе пульсации давлени вл ютс максимальн 1ми и интенсифицируют процесс разрушени отложений примесей на теплопередающих поверхност х за счет возникновени больших касательных напр жений.gas bubbles. The pressure pulsations that occur during resonance are maximally 1 mi and intensify the process of destruction of impurity deposits on heat transfer surfaces due to the occurrence of large tangential stresses.
Использование предлагаемого способа повышает эффективность процесса очистки за счет интенсифицирующего воздействи на отложени примесей импульсов давлени , возникающих при резонансных осцилл ци х газовых пузырей .The use of the proposed method increases the efficiency of the purification process due to the intensifying effect on the deposition of impurities of pressure pulses arising from the resonant oscillations of gas bubbles.
