Filter element device, filter and application of filter

Abstract

The invention discloses a filter element device, a filter and application of the filter. The filter element device comprises a filter element shell, at least one filter assembly and an inner barrel which are sequentially arranged in a sleeving mode from outside to inside, a first channel is formed between the filter assembly and the filter element shell, a distributor is arranged at the upper endof the filter element device, and a filter element liquid inlet is longitudinally formed in the distributor and used for evenly distributing liquid to be filtered to the filter element liquid inlet. The first channel directly communicates with the filter element liquid inlet, a filter element liquid outlet is formed in the lower end of the filter assembly, and to-be-filtered liquid entering from the filter element liquid inlet sequentially passes through the first channel and the filter assembly and then flows out from the filter element liquid outlet; and the filter element device is dividedinto a central liquid storage area and a peripheral filtering area which are independent from each other by the inner barrel, and a second channel is formed in the lower end of the inner barrel. Whenthe filter is used for removing solid inclusions in high-temperature molten salt, the filter can work continuously, and the filter element device is long in service life, good in filtering effect, convenient and flexible to install, small in occupied area and reasonable and compact in structure.

Description

technical field [0001] The invention relates to a filter element device, a filter and applications thereof. Background technique [0002] The high-temperature molten salt reactor experiment uses a mixture of molten salt as fuel. Due to operation, mechanical scouring or other reasons, a small amount of metal in the pipe or container will fall off into the molten salt under the scouring of molten salt, and then partially oxidized, becoming Solid inclusions enter the molten salt. If these solid inclusions are allowed to stay in the molten salt, it will increase the risk of blockage of pipeline valves in the subsequent process and interfere with the routine monitoring of corrosion conditions during equipment operation. Therefore, in order to ensure the long-term stable operation of the system, it is necessary to regularly filter and purify the molten salt to remove solid inclusions. [0003] At present, there is no effective removal process scheme or filter for solid inclusions...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome that there is no filter and process scheme suitable for filtering solid inclusions in high-temperature molten salt in the prior art. The filter cannot be used to filter high-temperature molten salt, and the existing filter is generally connected with an external liquid storage chamber to store the filtered liquid, which has defects such as a large footprint and an uncompact structure.
