Tam sim no, ib tug loj npaum li cas ntawm cov khib nyiab incineration slag yog siv nyob rau hauv lub tsev cov ntaub ntawv, xws li civil structural txheej cov ntaub ntawv, zus tau tej cov cement, bricklaying, thiab lwm yam. Txawm li cas los, domestic khib nyiab incinerator slag muaj ib tug loj tus naj npawb ntawm pore lug, uas muaj feem xyuam rau. engineering yam ntxwv ntawm domestic pov tseg incineration slag ua lub tsev khoom. Txoj kev kho ntawm cov khib nyiab hauv tsev incineration slag muaj cov hauv qab no:
(1) Siv cov khoom siv hluav taws xob tshiab uas tau muab pov tseg rau hauv lub thawv kaw nrog lub tshuab ua pa, thiab quab yuam cua rau huab cua;
(2) Soak cov huab cua hauv tsev pov tseg incineration slag hauv kev sib xyaw ntawm nano silica thiab nano calcium carbonate;
(3) Tshem tawm cov dej khib nyiab pov tseg hauv tsev thiab ua kom qhuav, thiab tom qab ntawd txias rau hauv chav sov.
Nyob rau hauv tus txheej txheem ntawm kev quab yuam cua, huab cua tsis tu ncua oxidizes cov organic teeb meem nyob rau hauv lub domestic pov tseg incineration slag nyob rau hauv ib tug kub thiab av noo ib puag ncig kom cov organic teeb meem cov ntsiab lus tsawg tshaj li 1.5%, uas txo qhov tsim ntawm cov voids tshiab nyob rau hauv kev siv ntawm domestic pov tseg. incineration slag thiab txhim kho stability ntawm domestic pov tseg incineration slag. Nyob rau tib lub sij hawm, cov pa roj carbon dioxide nyob rau hauv cov huab cua thiab cov dawb hnyav hlau nyob rau hauv lub domestic pov tseg incineration slag carbonize los ua carbonates, uas txhim kho cov stability ntawm hnyav hlau nyob rau hauv ib puag ncig.
Cov huab cua ntim thiab qhov cua lub sij hawm nyob rau hauv cov txheej txheem ntawm kev kho huab cua muaj kev cuam tshuam zoo rau kev hloov kho ntawm slag. Qhov zoo dua, qhov cua ntim hauv cov kauj ruam (1) yog 0.4-0.8m3/kg·min, lub sijhawm cua tshuab yog 70 ~ 80h, thiab qhov ntsuas kub hauv kauj ruam (1) yog {{8 }} degree thaum huab cua.
Qhov cua nkag hauv qab no {{0}}.4m3/kg·min yuav ua rau txo cov organic teeb meem degradation efficiency nyob rau hauv cov khib nyiab incineration slag, thiab qhov cua qhov cua siab tshaj 0.8m3/kg·min yuav ua rau poob loj ntawm cov khoom me me ntawm cov khib nyiab hauv tsev incineration slag, thiab cov nyhuv degradation ntawm cov organic teeb meem thiab qhov tsis zoo ntawm slag nyob rau hauv qhov nyiam ntau ntawm 0. ib qhov zoo. Lub sijhawm cua tshuab cuam tshuam rau qib ntawm degradation thiab degradation tus nqi ntawm cov organic teeb meem, qhov cua lub sij hawm tsawg tshaj li 70h yuav ua rau tsis tiav degradation ntawm cov organic teeb meem, qhov cua lub sij hawm siab tshaj 80h, degradation ntawm organic teeb meem yuav qeeb, thiab yuav ua rau cov av nplaum. ntawm cov khib nyiab incineration slag, cuam tshuam rau lub xeev particle ntawm slag, tswj nyob rau hauv 70 ~ 80h, organic teeb meem yuav degraded kiag li, thiab tus degradation tus nqi kuj ua tau raws li qhov yuav tsum tau ntawm lub cub tawg rau particle xeev.
Nyob rau hauv cov txheej txheem soaking, nano silica thiab nano calcium carbonate sau lub pores nyob rau hauv lub slag, txo cov porosity ntawm domestic pov tseg, thiab ua rau kom lub zog compressive ntawm domestic khib nyiab incineration slag ua lub tsev cov khoom. Nyob rau tib lub sijhawm, lub encapsulation ntawm nano silica thiab nano calcium carbonate tau siv los txo qhov kev sib cais ntawm cov hlau hnyav hnyav hauv cov khib nyiab hauv tsev incineration slag.
