Iyo yakawanda yakapararira asphalt fume ine huwandu hwe5-7mg/m~3 inogadzirwa panguva yekugadzirwa kwekabhoni workshop yealumina chirimwa.Kana iyo yakanyatsoburitswa, ichava nemhedzisiro yakakomba kune yakatenderedza uye nevashandi vefekitori.Tichitarisa pautsi uhwu, diki diki calcined coke inoshandiswa kuitora nekuichenesa, uye iyo yakazara calcined coke inogadzirwa patsva nenzira yekupisa patsva.

Chekutanga, iyo adsorption process ye calcined coke yakadzidzwa, uye mhedzisiro yekupisa adsorption, pitch fume concentration, space velocity uye particle size yecalcined coke pane adsorption mhedzisiro yecalcined coke yakaongororwa.Mhedzisiro dzetsvagiridzo dzinoratidza kuti huwandu hwehutsi hunoshongedzwa necalcined coke hunowedzera nekuwedzera kweiyo inlet conlet yepitch fume.Yakaderera nzvimbo velocity, yakaderera tembiricha, uye diki diki saizi zvese zvinobatsira pakushambadza kwehutsi hwenamo necalcined coke.Iyo adsorption thermodynamics ye calcined coke yakadzidzwa, iyo yakaratidza kuti adsorption process yaive yepanyama adsorption.Kudzokororwa kweiyo adsorption isotherm kunoratidza kuti adsorption process inoenderana neLangmuir equation.

Chechipiri, kupisa kutsva uye kudzoreredza kudzoreredza kweyakazara calcined coke.Mhedzisiro yeanotakura gasi kuyerera mwero, tembiricha yekudziya, yakazara calcined coke huwandu uye nguva dzekuzvarwa patsva pakuvandudza kushanda kwe calcined coke zvakaongororwa zvichiteerana.Mhedzisiro yekuedza inoratidza kuti kana mutakuri wegasi wekuyerera uchiwedzera, tembiricha yekudziya inowedzera, uye huwandu hwecoke mushure mekuzara calcining hwadzikira, zvinobatsira kuvandudza kushanda patsva.Condensate uye tora regeneration muswe gasi, uye kupora mwero iri pamusoro 97%, izvo zvinoratidza kuti condensation uye absorption nzira anogona kudzoreredza bhitumini ari regeneration muswe gasi zvakanaka.

Chekupedzisira, iwo matatu masisitimu ekuunganidza gasi, kucheneswa uye kuvandudzwa kwakagadzirwa, uye mhedzisiro yekugadzira inoiswa mukuita.Mhedzisiro yekushandiswa kwemaindasitiri inoratidza kuti kucheneswa kweasphalt fume nebenzo(a)pyrene kunosvika 85.2% uye 88.64%, zvichiteerana, kana muchenesi uchishandiswa kubata nekuchenesa utsi hweasphalt hwakapararira uye husina kurongeka.Kuwanda kwehutsi hweasphalt uye benzo (a) pyrene pakubuda kwemuchenesi yaive 1.4mg/m~3 uye 0.0188μg/m~3, uye kuburitsa kwaive 0.04kg/h uye 0.57×10~(-6)kg. /h, zvichiteerana.Yasvika pachiyero chechipiri chekubuda kwakazara kwezvinosvibisa mweya GB16297-1996.
