Изобретение относитс  к эксплуатации щелочных аккумул торов.This invention relates to the use of alkaline batteries.

В процессе эксплуатации никель-железных аккумул торов происходит снижение их емкости , причиной которого  вл етс  отравление положительного электрода вредными примес ми магни , кальци  и железа, попадающими в активную массу окисно-никелевого электрода в результате выщелачивани  активной массы отрицательного электрода, а также в результате использовани  жесткой воды дл  промывки аккумул торов и дл  приготовлени  электролита .During the operation of nickel-iron batteries, their capacitance decreases, the cause of which is the poisoning of the positive electrode with harmful impurities of magnesium, calcium and iron, which fall into the active mass of the nickel oxide electrode as a result of leaching the active mass of the negative electrode and also using hard water to wash the batteries and to prepare the electrolyte.

Известен способ восстановлени  емкости щелочного аккумул тора путем многократной промывки и кип чени  в дистиллированной воде (1).There is a known method of restoring an alkaline battery capacity by repeated washing and boiling in distilled water (1).

Однако такой способ малоэффективен, длителен-- (18-20 час) и непригоден дл  аккумул торов с гофрированным винипластовым сепаратором , поскольку в этом случае происходит распр мление гофра и усадка сепаратора.However, this method is inefficient, long-lasting (18-20 hours) and unsuitable for batteries with a corrugated vinyl plastic separator, since in this case the corrugation and shrinkage of the separator occur.

Известен также способ восстановлени  емкости никель-железного аккумул тора, наиболее близкий к предлагаемому по те-хнической сущности и достигаемому результату, путем обработки щавелевой кислотой (2).There is also known a method of restoring the capacity of a nickel-iron battery, which is closest to that proposed by the technical essence and the achieved result, by treating with oxalic acid (2).

Однако этим способом можно удалить из положительного электрода лищь отравл ющиеHowever, this method can remove from the positive electrode only the poisonous

соединени  железа, но не соединени  кальци  и магни .iron compounds, but not calcium and magnesium compounds.

Дл  повыщени  эффективности восстановле- , ни  емкости аккумул тора за счет удалени  сульфатов кальци  и магни  по предлагаемому способу в качестве органического соединени  берут 30-60%-ный раствор глицерина и обработку провод т в течение 35-45 мин.To increase the efficiency of reducing the capacity of the battery by removing calcium and magnesium sulfates, the proposed method takes 30-60% glycerin solution as an organic compound and processes it for 35-45 minutes.

Предлагаемый способ осуществл ют следующим образом.The proposed method is carried out as follows.

Аккумул тор с предварительно слитым электролитом промывают дистиллированной водой до прекращени  вытекани  шлама. Затем в аккумул тор заливают 30-60%-ный ра-створ глицерина, который сливают через 35-45 мин дл  повторного использовани , а затем два-три раза промывают дистиллированной водой с последующим заполнением электролитом ..,The battery with the pre-drained electrolyte is washed with distilled water until the sludge is no longer flowing. Then, 30-60% glycerol solution is poured into the battery, which is drained after 35-45 minutes for reuse, and then two or three times washed with distilled water, followed by filling with electrolyte ..,

Пример. В аккумул торы ТЖ-50 с предварительно слитым электролитом и очищенные от щлама проточной водой заливают глицерин марки «технический в количестве 0,5 кг наExample. TZH-50 batteries with a pre-drained electrolyte and cleared of the mud with running water are filled with technical grade glycerin in the amount of 0.5 kg per

одИн аккумул тор. Затем аккумул торы доливают водой и выдерживают 35-45 мин до полной экстракции сульфатов кальци  и магни  в раствор глицерина. Далее раствор глицерина сливают, аккумул торы промываютONE BATTERY. The batteries are then filled with water and allowed to stand for 35-45 minutes until complete extraction of calcium and magnesium sulphates into the glycerin solution. Next, the glycerin solution is drained, the batteries are washed

два-три раза водой и заполн ют электролитом.two to three times with water and filled with electrolyte.

После выдержки 2-3 час с электролитом дл  пропитки электродных масс провод т зар диый цикл в течение 10 час. Результаты испытаний следующие.After soaking for 2-3 hours, the electrolyte is used to impregnate the electrode masses for a 10-hour charge cycle. The test results are as follows.

Емкость, А-часCapacity, Ah

.Примечание: Разр д током 5 часового режима.Note: Discharge current 5 hour mode.

Таким образом аккумул торы ТЖ-50, отдающие 60-70% емкости, после обработки глицерином восстанавливают номинальную емкость .Thus, TZH-50 batteries, giving up 60-70% of capacity, after processing with glycerin, restore the nominal capacity.
