Cov Ntawv:
- 3 hli pellets: zoo meej rau kev ntxuav cov ntawv thov vim lawv qhov loj me.
- 10 hli / 16 hli nrog: siv rau kev tsim cua txias thiab tsheb thauj mus los xav tau .
Txoj Kev Muaj: Ua Kua Coos Pelletizing System
Lub Hom Yjo2 tau ua tiav cov khoom lag luam tu cov khoom lag luam qhuav tshaj plaws hauv Suav teb, muab tag nrho cov kev ua haujlwm tag nrho los ntawm cov khoom siv raw los ntawm cov khoom siv raw los ntawm cov khoom siv cov khoom siv rau cov khoom siv rau cov khoom siv rau cov khoom siv rau cov khoom siv rau cov khoom siv rau cov khoom siv rau cov khoom siv rau cov khoom siv {}}
Peb Qhuav Dej khov Ntau Lawm Txheej Txheem:
Kauj Ruam 1: Peb muab cov dewar fwj kom khaws cov roj carbon dioxide (l 3,}}}
Kauj Ruam 2: Txuas lub taub hau deewar rau cov pelletizer qhuav {}} Cov dej khov ua kua los ntawm cov khoom noj khoom haus kom huv si, "uas yog qhov uas nws nkag siab rau hauv pelast.
Kauj Ruam 3: Vim tias qhuav dej khov sublimates yooj yim, peb muab cov dej khov ultra tsis tuaj yeem khaws cia kom tsawg li 0 {{7 ‰.
Kauj Ruam 4: Peb muab ntsia hlau siv cua compressors nrog lub zog hluav taws xob nrog 7 {}} 5 txog 10 . 31 m³ / h. Lawv txhawb ob qho tib si 220V thiab 380V voltages thiab xa ruaj khov siab cua siab cua rau cov dej khov tshuab blasting.
Kauj Ruam 5: Huab Cua Siab Cov Lus Qhia Txog Cov Khoom Siv Hluav Taws Xob kom huv si los txhawm rau cov roj, tar, hmoov av, thiab asphalt .
Vim li cas ua kom qhuav hauv tsev tsis pom zoo:
{{0 {}} yuav tsum tau siab heev:
Tig cov pa roj carbon dioxide rau hauv cov kua yuav tsum tau muaj tsawg kawg yog 5 {{{1} 5.1
{{0 {}}} Tsis tshua muaj cua sov tsawg tsawg:
Cov dej khov qhuav yog cov khoom tawv ntawm cov pa roj carbon dioxide (hloov ncaj qha rau cov roj ({} daim ntawv .
{{0 {}} pheej hmoo ntawm txias txias:
Dej khov txias heev, nrog qhov kub ntawm -78.5} frostbite-zoo ib yam li kev kub siab, tab sis tshwm sim los ntawm huab txias {}}
4. kev pheej hmoo ntawm asphyxiation:
Nyob rau hauv chav tsev kub, dej khov solimates sai heev, tso cov pa roj carbon monoxide ntau dua, lossis ua pa tawm hauv cov pa roj carbon monoxide. Tshawb .
{{05. tawg cov kev phom sij los ntawm cov thawv ntim khoom:
Txawm hais tias koj tswj kom tau txais cov khoom siv ua kua (feem ntau khaws cia ua kom muaj zog lossis cov khoom siv tiv thaiv kom tsis muaj zog los yog kev tiv thaiv kev tiv thaiv kom nrawm nrawm
{{0 {}} Tsis muaj cov khoom siv tshaj lij:
Nyab xeeb thiab khaws cia co₂, nrog rau ua cov khoom siv dej khov xws li cov ntaub hnab looj tes ua kom siab, thiab lub ntsej muag zoo nkauj, thiab cov khoom siv tshuaj txhuam hniav rau txhua lub sijhawm.
{{0 {}} ua tsis tau zoo thiab tsis muaj tseeb:
Txawm hais tias koj tswj hwm cov dej khov qhuav me txawm tias muaj kev pheej hmoo tsawg (vim tias cov khoom siv hauv tsev noj mov tsis muaj peev xwm txo tau qhov muaj txiaj ntsig tsawg)
Kev Khib Khov Qhuav: Cov ntsiab cai thiab kev pab
Qhuav dej khov ntxuav, siv cov khoom siv dej khov rau 3 hli kom huv ntawm cov kab tsuag kom huv ntawm peb lub hauv paus ntsiab lus tseem ceeb:
- Thermal poob siab: tus mob khaub thuas ({-78.5 degree) ua rau muaj cov paug tsis huv, thiab tawg kom yooj yim dua.
- Roj nthuav dav: thaum cuam tshuam, qhuav dej khov, nthuav tawm 700 zaug hauv ntim kom nqa thiab dislodge still .
- Residue-dawb tu: qhuav epaporates kiag li, tawm tsuas yog cov khoom noj ua paug rau qhov yooj yim pov tseg {}}
Qhov Zoo:
- Ib puag ncig tus phooj ywg: tsis muaj cov tshuaj seem tshuaj, muaj kev nyab xeeb rau ib puag ncig .
- Tsis yog abrasive: ntxuav yam tsis muaj kev puas tsuaj rau qhov chaw .
- Dej tsis muaj dej: Tshem tawm cov cim dej thiab qhov xav tau kom qhuav .
- Tsis nres kev ua haujlwm: tso cai tu thaum lub sijhawm ua haujlwm, txo qis downtime .
- Nqi-tsim nyog: txo cov nqi khib nyiab pov tseg vim tsis muaj kev ua kom huv si.
Nrhiav rau ib-nres muaj cov dej khov dej khov tshiab qhuav
Yjco2 tau ua ke feem ntau cov dej khov kho cov khoom siv hauv Suav, peb tuaj yeem muab cov khoom siv ua tiav rau peb, peb tuaj yeem paub cov pa dej qhuav txog kev daws teeb meem qhuav {}}
