Submicron　particulate　emissions　from　coal-fired　power　plants　play　an　important　role　in　causing　atmospheric　pollution　and　affecting　human　health.　In　this　work,　an　experimental　platform　of　turbulent　agglomeration　for　submicron　particulates　was　built.　The　microscopic　morphology　of　the　turbulent　agglomeration　was　measured　through　Field　Emission　Electron　Microscopy　(FESEM),　while　the　particle　size　distributions　before　and　after　the　agglomeration　were　measured　through　Scanning　Mobility　Particle　Sizes　(SMPS).　The　results　show　that　the　submicron　particulates　form　a　multi-branched　particle　tree　structure　in　the　process　of　the　turbulent　agglomeration.　At　the　inlet　velocity　of　0.8∼5.3　m/s,　the　removal　efficiencies　of　PM1　and　PM0.1　are　5.6%∼18.6%　and　7.0%∼21.4%,　respectively.　The　removal　efficiency　curve　presents　quadratic　function　law　with　the　change　of　the　inlet　velocity.　©　2020,　Science　Press.　All　right　reserved.
