Description

Изобретение относитс  к области теплотехники и может быть использовано при промывке теплообменников, например конденсаторов, паровых турбин.The invention relates to the field of heat engineering and can be used when washing heat exchangers, such as condensers, steam turbines.

Известны способы промывки теплообменника путем организации обратного хода охлаждающей воды.Known methods of washing the heat exchanger by organizing reverse cooling water.

Предлагаемый способ отличаетс  от известных тем, что в выходной водовод подают воздух под давлением и затем соедин ют входной водовод, например с использованием быстродействующего клапана, с полостью пониженного давлени .The proposed method differs from the known ones by supplying pressurized air to the outlet conduit and then connecting the inlet conduit, for example, using a high-speed valve, to a reduced-pressure cavity.

Такое осуществление способа позвол ет повысить эффективность промывки.Such an implementation of the method makes it possible to increase the washing efficiency.

Предлагаемый способ иллюстрируетс  чертежом .The proposed method is illustrated in the drawing.

Промывка теплообменника осуществл етс  следующим образом.The heat exchanger is washed as follows.

Теплообменник / отключают путем закрыти  задвижек 2 « 3 на входном И выходном водоводах 4 и 5.The heat exchanger is turned off by closing the valves 2 "3 at the input And output conduits 4 and 5.

В выходной водовод 5, а при необходимости в верхнюю часть вод ной камеры через патрубок 6, подают воздух под давлением, спуска In the outlet conduit 5, and if necessary in the upper part of the water chamber through the nozzle 6, pressurized air is supplied;

воду через дренажный вентиль 7. Зате.м дренажные вентили 7 и 8 закрывают и продолжают подавать воздух до достижени  давлени  большего, чем при нормальной работе теплооб .менника. После этого соедин ют входной водовод 4 с атмосферой при помощи быстродействующего клапана 9.water through the drain valve 7. Zatem. The drain valves 7 and 8 close and continue to supply air until a pressure is higher than during normal operation of the heat exchanger. After that, the inlet conduit 4 is connected to the atmosphere by means of a quick-acting valve 9.

Вода проходит по теплообменнику со скоростью в 1,5-5 раз большей нормальной рабочей скорости охлаждающей воды и смывает ил и посторонние предметы с внутренней поверхности трубок.Water passes through the heat exchanger at a rate of 1.5-5 times greater than the normal operating speed of the cooling water and flushes sludge and foreign objects from the inner surface of the tubes.

П р е д м е т и 3 о б р е т е н и  PRIORITY 3 ABOUT AND

Способ промывки теплообменника, имеющего входной и выходной водоводы, путем организации обратного потока охлаждающей воды,The method of washing the heat exchanger, with the input and output conduits, by organizing the reverse flow of cooling water,

отличающийс  тем, что, с целью повышени  эффективности промывки, в вы.ходной водовод подают воздух под давлением и затем соедин ют входной водовод, например с использованием быстродействующего клапана, с полостью пониженного давлени .characterized in that, in order to increase the washing efficiency, pressurized air is fed into the outlet conduit and then the inlet conduit is connected, for example, using a fast-acting valve, to a reduced-pressure cavity.
