The invention provides an experimental apparatus suitable for realizing an
oxygen-controlled reaction, and the experimental apparatus is used for
oxygen-controlled related experiments under the conditions of different temperatures and
oxygen concentration measurement control in lead-
bismuth. The device can be used for solving the problems of tight connection, disassembly and measuring accuracy of the device under a room-temperature
solid lead-
bismuth state and consists of a corrugated
pipe, an
oxygen measurement instrument, a
thermocouple, a stirrer, a connecting piece, a sealing
flange, an air inlet, an air outlet and a liquid outlet. According to the experimental apparatus, the corrugated
pipe is adopted for connection and sealing, the ascending and descending of the stirrer and the
oxygen measurement instrument are realized, and the problem that the reaction apparatus cannot be sealed under the room-temperature
solid lead-
bismuth state can be solved; simultaneously, the
thermocouple and the
oxygen measurement instrument are connected by virtue of the connecting piece, so that the synchronous ascending and descending of the
thermocouple and the oxygen measurement instrument is realized, the
temperature measurement of liquid lead-bismuth adjacent to the oxygen measurement instrument is realized, and the temperature corresponding to the
signal of the oxygen measurement instrument is more accurate; A blade of the stirrer is in threaded connection with a
metal connecting rod at the upper end, so that the disassembly is convenient, and simultaneously blades of different types can be replaced so as to realize different liquid lead-bismuth flow field flow field experiments; and the sealing
flange is used for connecting and sealing the oxygen measurement instrument and the thermocouple, so that replacement is convenient. The design of the device is especially suitable for the oxygen-controlled
experimental research on the liquid lead-bismuth with different temperature and flow velocity parameters.
