Изобретение предназначено дл  очистки жидкого лити  от азота и может примен тьс  в реакторах с литиевым теплоносителем.The invention is intended for the purification of liquid lithium from nitrogen and can be used in reactors with a lithium coolant.

Известен способ очистки жидких металлов от примесей, заключающийс  в том, что через жидкий металл, наход щийс  в некоторой емкости , пропускают электрический ток, под действием которого в металле происходит направленное перемещение примесей. Эффективность такой очистки на начальных этапах определ етс  подвижностью примеси, а предельна  степень очистки - величиной ее эффективного зар да.A known method for purifying liquid metals from impurities is that an electric current is passed through a liquid metal in a container, under the action of which directional movement of impurities occurs in the metal. The effectiveness of such purification at the initial stages is determined by the mobility of the impurity, and the ultimate degree of purification is determined by the value of its effective charge.

Хороща  очистка металла возможна, если эффективный зар д примеси не слишком мал, а в устройстве, реализующем данный способ, предусмотрены меры по предотвращению конвекции (например, с помощью системы капилл ров , помещенных в корпус ловущки).Fine metal cleaning is possible if the effective impurity charge is not too small, and the device implementing this method has measures to prevent convection (for example, using a system of capillaries placed in the trap body).

Однако применение подобных устройств, выполненных из никел , хрома, стали 1Х19Н10Т, дл  очистки лити  от азота непроизводительно из-за малой подвижности и малой величины эффективного зар да примеси азота в литииHowever, the use of such devices made of nickel, chromium, 1X19H10T steel, for the purification of lithium from nitrogen is unproductive due to the low mobility and low magnitude of the effective charge of the admixture of nitrogen in lithium

The drawing shows the proposed device.

Корпус ловушки 1 вместе с системой ка пилл ров 2, катодом 3 и анодом 4, выполнен ными из молибдена, помещен в нагревательное устройство 5 и соединен с источником 6 поступлени  очищаемого от азота лити , например контуром реактора. Прианодна  область ловушки соединена с емкостью 7 дл  сбора загр зненного азотом лити . После нагрева ловущки до определенной температуры и заполнени  ее литием из источника 6 наThe body of the trap 1, together with the system of capillaries 2, the cathode 3 and the anode 4, made of molybdenum, is placed in the heating device 5 and connected to the source 6 of the supply of nitrogen from nitrogen, for example, the reactor circuit. The anode area of the trap is connected to a tank 7 for collecting lithium contaminated with nitrogen. After heating the trap to a certain temperature and filling it with lithium from source 6 on

В результате этого взаимодействи  в литии образуютс Studies have shown that when heated to a certain temperature, molybdenum dissolved in lithium reacts with the nitrogen present in lithium. As a result of this interaction in lithium is formed
