Description

Предмет предлагаемого изобретени  составл ет устройство дл  подогревани  питательной воды на паровозах .The subject matter of the present invention is a device for heating feedwater on locomotives.

На прилагаемом чертеже схематически показано общее расположение всех частей устройства, причем сплошными толстыми лини ми обозначен трубопровод дл  подачи острого пара, а пунктирными - трубопровод дл  отработанного пара, подаваемого к подсобным механизмам.The accompanying drawing shows schematically the general arrangement of all parts of the device, with a solid thick line indicating the pipeline for the supply of live steam, and the dashed lines indicate the pipeline for the exhaust steam supplied to the auxiliary machinery.

Как показано на чертеже, м тый пар от паровой машины 7 поступает в специальный сборник 4, который служит дл  выравнивани  его давлени . На трубопроводе 2, соедин ющем сборник 4 с паровой машиной /, устанавливаетс  центробежный маслоотделитель 3.As shown in the drawing, the steam from the steam engine 7 is fed into a special collector 4, which serves to equalize its pressure. A centrifugal oil separator 3 is installed on line 2 connecting the collector 4 to the steam engine.

Из сборника одна часть м того пара по трубопроводу б направл етс  в расход щуюс  насадку 7, где, проход  через постепенно расшир ющиес  насадки, доводитс  до давлени  0,05 атм., при котором температура его составл ет 32,5°. В этом состо нии пар поступает в теплообменник 8, в который одновременно с ним подаетс  из сборника 4 по трубопроводу 5 остальна  часть м того .пара, не-подведенна  к расход щейс  насадке 7.From the collector, one part of that steam through pipeline b is directed to the diverging nozzle 7, where the passage through the gradually expanding nozzles is brought to a pressure of 0.05 atm at which its temperature is 32.5 °. In this state, steam enters the heat exchanger 8, which simultaneously with it is supplied from collector 4 through conduit 5, the rest of that pair, which is not connected to the diverting nozzle 7.

В теплообменнике расширившийс  до 0,05 атм. м тый пар получает дополнительное количество тепла от м того пара, подаваемого по трубопроводу 5 и имеющего температуру 140° и давление 1,5 атм., благодор  чему температура расширившегос  пара повышаетс  процессом перегрева до 100.In the heat exchanger expanded to 0.05 atm. The steam receives an additional amount of heat from the steam supplied through pipeline 5 and having a temperature of 140 ° and a pressure of 1.5 atm., thanks to which the temperature of the expanded steam rises to overheating by up to 100.

Далее перегретый пар, обладающий значительным запасом кинетической энергии, поступает в насадку или систему насадок 7а, суживающихс  в направлении давлени  пара, благодар  чему его давление и температура адиабатически повышаютс . Расчет показывает, что при прин тых выше параметрах температура пара может быть доведена в насадке а до 395° при давлении 0,7 KZjCM.Then, superheated steam, which has a significant amount of kinetic energy, enters the nozzle or nozzle system 7a, tapering in the direction of the vapor pressure, due to which its pressure and temperature increase adiabatically. The calculation shows that with the parameters accepted above, the steam temperature can be increased in the nozzle a to 395 ° with a pressure of 0.7 KZjCM.

Друга  часть м того пара, подаваема  в теплообменник по трубопроводу 5, отдава  в теплообменнике 5 свою теплоту, конденсируетс  и при помощи насоса 9 подаетс  в смесительный бак.Another part of that steam supplied to the heat exchanger through the pipeline 5, giving off its heat in the heat exchanger 5, is condensed and fed by the pump 9 to the mixing tank.

Из смесительного бака насосом 12 вода гонитс  во второй работающийFrom the mixing tank, the pump 12 drives the water to the second one
