Abstract

The invention provides an online sampling method and an online sampler. The online sampling method is executed by using the online sampler. The online sampler comprises a vacuum ball valve, a vacuum tube, a sampling push rod and a sampling crucible, wherein the vacuum ball valve comprises a first end opening and a second end opening which are communicated with each other; one end of the vacuum tube is communicated with the second end opening and the other end of the vacuum tube is a closed end; the sampling push rod extends into the vacuum tube from the closed end of the vacuum tube and extends out of the first end opening after passing through the vacuum ball valve; the sampling crucible is connected with the rod end, extending out of the first end opening, of the sampling push rod; the first end opening is communicated with an equipment cavity to be sampled. The online sampling method provided by the invention is simple and rapid to operate, does not interfere with the normal operation of sampled equipment and does not disturb the working atmosphere inside the sampled equipment.

Description

technical field

[0001] The invention relates to an online sampling method and an online sampler. Background technique

[0002] Molten salt is a high-temperature melt composed of metal cations and non-metal anions. It has the characteristics of good thermal stability, low vapor pressure, low viscosity, good electrical conductivity and large heat capacity. Therefore, molten salt is used in nuclear energy fields such as dry reprocessing and molten salt reactors.

[0003] With the proposal and development of advanced nuclear energy systems such as fast reactors and molten salt reactors, the closely related dry reprocessing technology has attracted more and more research and attention from various countries. In various dry reprocessing processes, it is often necessary to The liquid molten salt in the equipment is sampled and analyzed in real time.

[0004] In the existing sampling technology, the molten salt in the equipment is generally randomly sampled, and the molten salt co...
