Abstract

The invention provides a filtering collector. The filtering collector comprises an inlet adapter flange, an inlet companion flange, an outer sleeve, an inner sleeve, a plurality of filtering elements, an outlet companion flange and an outlet adapter flange, wherein a first end face of the inlet companion flange is connected with the inlet adapter flange, a second end face of the inlet companion flange is connected with a first end face of the outer sleeve, a first end face of the outlet companion flange is connected with a second face of the outer sleeve, a second end face of the outlet companion flange is connected with the outlet adapter flange, the filtering elements and the inner sleeve are located inside the outer sleeve, the inner sleeve is contacted with one end of each filtering element, the end of each filtering element is close to the outlet companion flange, and the diameter of a filtering hole of one end of each filtering element, which is close to the inlet companion flange, is larger than the diameter of a filtering hole of the end of the filtering element, which is close to the outlet companion flange. The filtering collector can gradually filter and collect radioactive graphite powder in helium gas in a loop according to particle sizes under high temperature and high pressure, and no helium gas leaks out or leaks through intervals among the inner wall of the outer sleeve and the filtering elements.

Description

technical field [0001] The invention relates to the technical field of reactor engineering, in particular to a filter collector for collecting radioactive graphite dust in the helium gas in the primary circuit of a high-temperature gas-cooled reactor. Background technique [0002] High-temperature gas-cooled experimental reactor HTR-10 is the only pebble-bed high-temperature gas-cooled reactor currently in operation in the world. The way of the core is very similar to the HTR-PM (High Temperature Modular Pebble Bed Reactor Project), a pebble bed modular high temperature gas-cooled reactor nuclear power plant project. To study the release behavior of fission products in the high temperature gas-cooled reactor and the transport behavior in the primary circuit, obtain the law of the fission product behavior, and thus obtain the direct verification of the radiation safety of the high temperature gas-cooled reactor, which is not only a demonstration of the inherent safety of the ...
