The　low-low　temperature　electrostatic　precipitator　has　been　applied　to　enhance　the　efficiency　of　power　plants.　In　this　paper,　the　influences　of　chemical　constitutions　on　the　adsorption　properties　of　particulate　matters　with　vitriolic　acid　and　the　agglomeration　after　adsorption　are　researched.　Experiments　are　conducted　on　a　one-dimensional　adsorption　system,　which　simulates　the　working　environment　of　low-low-temperature　electrostatic　precipitator.　The　consequences　display　that　the　agglomeration　between　particulate　matters　in　scanning　electron　microscopy　are　loose　pellets　agglomeration　together,　adhesion　of　loose　pellets　to　massive　particles,　and　massive　particles　agglomeration　together.　For　Na　and　K,　the　amounts　of　elements　added　have　little　effect　on　the　adsorption　of　the　sulfuric　acid　by　ash　particles.　For　Mg,　Fe,　and　Ca,　when　the　oxide　is　used　as　an　additive,　the　adsorption　capacity　of　ash　samples　to　the　vitriolic　acid　was　enhanced　and　the　agglomeration　phenomenon　of　the　ash　granules　was　more　remarkable　with　increasing　elements　amounts.　In　addition,　the　change　of　Mg　has　great　impact　on　vitriolic　acid　adsorption　and　granules　agglomeration.　©　2022,　Tsinghua　University　Press.
