Description

щий давление 0,5 ата и температуру , отводимый от выпарной установки предыдущей стадии технологического процесса. Из последнего вакуум-кристаллизатора отвод т 131|6 т/ч суспензии .HHbCl. Средний коэф s фициент теплопередачи в конденсаторах равен 274 ккал/м. , средн   полезна  разность температур равна , средн   удельна  теплова  нагрузка составл ет 6165 ккал/м -ч. Расход пара (Р 10 ата, ю Ь 280 с) на зжекто1х 1 равен 586кг/ч. В 9ТИХ услови х на конденсацию пара, примен емого дл  перемешивани  суспензии, требуетс  47 м теплопередаюшей поверхности,, . 2,53% от общей поверхности конденсатора 115the pressure is 0.5 atm and the temperature removed from the evaporator of the previous stage of the technological process. From the last vacuum crystallizer, 131 | 6 t / h of .HHCl suspension is withdrawn. The average heat transfer coefficient in capacitors is 274 kcal / m. The average useful temperature difference is equal, the average specific heat load is 6165 kcal / m -h. Steam consumption (P 10 ata, s, 280 s) per zzhekto1kh 1 is 586 kg / h Under 9 of these conditions, steam condensation used to mix the slurry requires 47 m of heat transfer surface. 2.53% of the total surface of the capacitor 115

По известному способу прииспользовшиц .воздуха в качестве перемешивающего агента -дл  такой же батареи коэффициент теплопередачи (средний) равен 262 ккал/м ч °С,By a known method, when using air as a mixing agent, the same battery has a heat transfer coefficient (average) of 262 kcal / m h ° С,

полезна  разность температур снижаетс  до 21,9°С, удельна  теплова  нагрузка падает до 5738 ккал/м -jK Расход пара на эжекторы . составл ет 1876 кг/ч. Теплопередающа  поверхность, необходима  дл  конденсации пара, расходуемого на эжекторы, равна 212 м (ll,4% от общей поверхности конденсаторов).the useful temperature difference decreases to 21.9 ° C, the specific heat load drops to 5738 kcal / m -jK Steam consumption for ejectors. is 1876 kg / h. The heat transfer surface, necessary for the condensation of steam consumed on ejectors, is equal to 212 m (ll, 4% of the total surface of the capacitors).
