Abstract

As the core equipment of wet-type Filtered Containment Venting System (FCVS), the self-priming venturi scrubber has the characteristics of passive operation, reliable work, and superior filtration performance, and is widely used in the design of active nuclear power plant systems. In this paper, the filtration performance of the venturi scrubber is taken as the evaluation index, and the venturi scrubber is optimized by using a combination of numerical calculation and experimental based on the structure of the stirring baffle. By controlling the two structural parameters of the axial setting height and the area ratio of the gas phase opening, the effect of structural parameters of the stirring battle on the two-phase flow characteristic and atomization characteristic of the venturi scrubber was obtained. Subsequently, coupling CFD and dust particle capture theory to theoretically calculate the filtration efficiency, combined with experimental verification, the structural parameters of the stirring baffle with the best filtration performance were obtained. The results show that compared with the traditional venturi scrubber, the venturi scrubber with a stirring baffle with an axial height of 120 mm and an area ratio of gas phase opening of 0.8 can achieve a filtration efficiency of more than 99.9% for aerosols with a low flow resistance. Finally, the optimization suggestions for the structure of the stirring baffle were proposed. This paper is of great significance for the upgrading of the venturi scrubber and the optimization of the nuclear industry and systems.

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
