Meticulously engineered rau qhov zoo purification ntawm PMMA pyrolysis kua, no batch - hom nqus tsev rectification kem rau MMA suav nrog txiav- ntug nqus batch distillation tshuab. Nws muaj peev xwm ua tsis tu ncua ua MMA monomer kev daws teeb meem nrog purity ntawm 98% lossis siab dua, ua tiav txhua lub voj voog ua haujlwm tsis pub dhau 11 teev. Lub kaw lus nta ob hom kev ua haujlwm - phau ntawv thiab PLC-raws li kev tswj hwm tus kheej - muab qhov tshwj xeeb yooj yim rau kev ua kom haum raws li ntau hom kev xav tau. Tsis tas li ntawd, nws ua rau kev pib sai thiab kaw, ua rau nws zoo kawg nkaus haum rau ib puag ncig uas cuam tshuam nrog kev teem sijhawm ntau lawm thiab kev hloov kho.
Cov kauj ruam ua haujlwm
1. Pub thiab Nqus Tsev Ua ntej- pib theem
Siv lub siab - ua kua ua tau zoo- lub tshuab nqus tsev twj tso kua mis, crude MMA monomer yog precisely kos rau hauv lub tshuab hluav taws xob distillation, thiab lub kaw lus siab raug txo kom nrawm rau lub tshuab nqus tsev ntawm 10-50 kPa. Lub tshuab hluav taws xob distillation yog preheated rau qhov kub ntawm 60-80℃(20-40℃qis dua qhov kub kub ntawm atmospheric siab); ib txhij, lub overhead condenser yog qhib ua ntej rau ua ntej -txias, tuav ib tug kub gradient ntawm 50-70 degree. Tus reflux piv yog raug rau kev txawj ntse tswj.
Thaum pib theem, tag nrho cov kev ua haujlwm reflux yog siv los xyuas kom meej qhov sib cais ntawm cov khoom hauv kab.
2. Thaum lub purity ntawm lub overhead condensate mus txog 90%, cov txheej txheem sau rau tsim nyog MMA monomer yog pib, thiab cov khoom yog pauv mus rau refined monomer cia tank.
3. Ib qho kev sib xyaw ua ke, siab -cov pa roj chromatograph xyuas qhov muaj pes tsawg leeg hauv cov khoom sib cais hauv lub sijhawm; Yog tias qhov purity raug kuaj pom tias poob qis dua li tus qauv xav tau, lub condensate reflux mechanism tau tshwm sim tam sim ntawd.
4. Tshem tawm qhov seem thiab qhov system rov pib dua
Thaum qhov ntsuas kub ntawm cov kab hauv qab tau kuaj pom tias siab tshaj 85℃- qhia tias muaj kev nce ntxiv hauv cov ntsiab lus ntawm cov khoom hnyav - lub kaw lus kaw cov khoom tawm valve. Nitrogen gas is then used to pressurize the system and safely discharge the remaining residue into a waste liquid tank, thereby effectively preventing the polymerization of residual MMA.
5. Tom qab ua tiav ntawm ib lub voj voog ua haujlwm ib zaug, lub kaw lus cia li ua tiav cov txheej txheem depressurization los kho lub siab mus rau theem atmospheric, kom muaj kev npaj txhij rau kev ua haujlwm ntawm cov khoom tom ntej.
Kev piav qhia ntawm Qhov Zoo
Exceptional Start-up and Shutdown Convenience
● Ib qho -Kov Pib: Siv lub tshuab nqus tsev ua ntej- khiav tawm, lub kaw lus tsuas siv 15 feeb kom ncav cuag lub hom phiaj nqus tsev (10–50 kPa). Lub tshuab cua sov siv qhov kev tswj hwm qhov kub thiab txias PID algorithm, boosting tus nqi cua sov los ntawm 20% piv rau ib txwm siv.
● Intelligent Shutdown Sequence: Tom qab ua tiav ntawm kev khiav haujlwm, PLC tau ua tiav cov txheej txheem kaw - suav nrog kev txo qis, cov kua dej seem, thiab cov condenser khoob - seamlessly txhawb nqa tau zoo, txuas ntxiv ntau-batch ntau lawm.
● Tsawg-Kev Tsim Kho: Tom qab kaw, tsis tas yuav tsum tau ntxuav cov khoom ntim; lub kaw lus hloov ncaj qha mus rau hauv hom standby, yog li txo cov nqi kho mob.
Qhov tseem ceeb ntawm kev ua haujlwm nqus tsev vacuum
● Zog- Ua tau zoo thiab muaj txiaj ntsig zoo: Nyob rau hauv lub tshuab nqus tsev, qhov kub ntawm MMA tau txo qis rau 60-80℃. Kev siv hluav taws xob cua sov yog txo los ntawm 30% piv rau kev ua haujlwm ntawm atmospheric siab; rau ib xyoos ua tiav ntim ntawm 10,000 tons ntawm cov kua tawg, qhov no txhais tau tias cov nqi txuag nyiaj ntau tshaj 1.2 lab RMB.
● Kev nyab xeeb thiab ruaj ntseg: Ib qho kev tsis zoo ntawm - kev tiv thaiv kev kub ntxhov yog siv thoob plaws hauv tag nrho cov txheej txheem (nrog rau kev hloov pauv siab tswj hauv ± 1 kPa), tshem tawm qhov kev pheej hmoo siab ntawm - kub pib-polymerization ntawm MMA.
● Lub Sijhawm Ua Tau Zoo: Cov yam ntxwv los ntawm kev pib luv luv-nce thiab kaw- lub sijhawm thiab kev ua haujlwm yooj yim, lub kaw lus tso cai rau qhov nruab nrab ntawm ob qhov kev ua haujlwm ib hnub. Kev siv cov cuab yeej siv tau txhawb nqa los ntawm 40% piv rau cov txheej txheem ib txwm muaj, ua rau muaj kev txhim kho tseem ceeb ntawm kev tsim khoom.
Kev txawj ntse tswj thiab siab Flexibility
● Seamless Dual-Kev Ua Haujlwm Hom: Hauv Hom Kev Taw Qhia, cov neeg ua haujlwm tuaj yeem hloov kho lub tshuab nqus tsev thiab reflux piv; nyob rau hauv PLC Tsis Siv Neeg Hom, lub kaw lus siv lub preset siab -kub profile kom dynamically them nyiaj rau qhov hloov pauv hauv cov kwj dej, kom ruaj khov thiab txhim khu kev qha khoom purity.
● Slexible Small-Batch Processing: Nrog ib lub peev xwm ntawm 15 mus rau 25 tons, lub kaw lus zoo kawg nkaus haum rau ntau hom kev siv - suav nrog PMMA pov tseg rov ua dua, kuaj R&D, thiab me me - mus rau - nruab nrab scale ntau lawm.
Kev txo qis hauv kev tu tus nqi
Cov cuab yeej tu lub voj voog tau txuas ntxiv mus rau 12 lub hlis, txo cov nqi tu txhua xyoo los ntawm 15% piv rau cov cuab yeej siv ib txwm siv, yog li ua kom muaj txiaj ntsig zoo rau kev ua haujlwm thiab cov txiaj ntsig kev lag luam.
Siv tau Scenarios
- Cov ntawv thov uas yuav tsum tau pib ntau zaus-ups, kaw, thiab lub sijhawm hloov pauv tau yooj yim - xws li chav kuaj R&D, me me - mus rau - nruab nrab - teev PMMA cov chaw tsim khoom, thiab PMMA cov khoom siv rov ua dua tshiab.
- Batch ntau lawm ib puag ncig uas xav tau sai sai rau kev hloov pauv hauv kev txiav txim lossis cov txheej txheem tsis ua haujlwm.
- Qhov txawv ntawm nws cov qauv tsim tshwj xeeb rau kev yooj yim ntawm kev pib- nce thiab kaw, cov khoom no tau tshwm sim los ua qhov kev xaiv muaj txiaj ntsig zoo thiab txhim khu kev qha hauv thaj chaw ntawm PMMA purification, xa cov kev yooj yim tsis tau pom dua thiab cov txiaj ntsig ua haujlwm rau cov neeg siv.
