У роботі наведено результати випробувань багатоступінчастого (5 ступенів) відцентрового дистилятора (СМЕД) з використанням для зниження енергоспоживання термоелектричного теплового насоса (ТТН). У дослідах вимірювали локальні (у режимі он-лайн) дані системи дистиляції, такі як температура рідин (вихідної й дистиляту) поточну продуктивність, загальний вміст солей, питому витрату енергії за різних швидкостей обертання ротора дистилятора, потужності ТТН, ступінь концентрування. Загальна тривалість випробувань склала понад 700 годин, кількість переробленої рідини (NaCl та урини) склала понад 2000 кг. Дослідження трьох дистиляторів і двох ТТН і порівняння їх результатів показало їхню ідентичність, що свідчить про високу якість виготовлення цих пристроїв. Отримані дані параметрів експлуатації (оберти n і потужність ТТН), можуть бути використані для оптимізації конструкції й режимів експлуатації роботи всієї системи СД + ТТН. Бібл. 28, рис. 8, табл. 1.
The work presents the results of testing a multi-stage (5 stages) centrifugal distiller (CD) with the use of a thermoelectric heat pump (THP) to reduce power consumption. In the experiments, measurements were made of the local (online) data of distillation system, such as the temperature of the liquids (initial and distillate), current production, total salt content, specific power consumption at different speeds of distiller rotor, ТНР power, and the degree of concentration. The total duration of the tests was more than 700 hours, the amount of processed liquid (NaCl and urine) was more than 2000 kg. The study of three distillers and two ТНРs and a comparison of their results showed their identity, which characterizes high quality workmanship of these devices. The obtained operating parameters (revolutions n and ТНР power) can be used to optimize the design and operating modes of the entire CD + ТНР system. Bibl. 28, Fig. 8, Tabl. 1.
