I-Polymer polyols (POP) uhlelo lokusabela
Incazelo Yomkhiqizo
Lolu hlelo lufanele ukusabela okuqhubekayo kwezinto zesigaba segesi-liquid ngaphansi kokushisa okuphezulu nokucindezela okukhulu.Isetshenziswa kakhulu ekuhlolweni kokuhlola izimo zenqubo ye-POP.
Inqubo eyisisekelo: amachweba amabili anikezwa amagesi.Ichweba elilodwa yi-nitrogen yokuhlanza ukuphepha;omunye umoya njengomthombo wamandla wevalvu yomoya.
Izinto eziwuketshezi zilinganiswa ngokunembile ngesikali se-elekthronikhi futhi zifakwe ohlelweni ngepompo eguquguqukayo engashintshi.
Okubalulekile kusabela kuqala ku-reactor yethangi elinyakaziswayo ngaphansi kwezinga lokushisa elimiswe ngumsebenzisi kanye nokucindezela, bese kukhishelwa ku-reactor ye-tubular ukuze kuqhubeke ukusabela.Umkhiqizo ngemva kokusabela ufinyezwa ku-condenser futhi uqoqwe ukuze uhlaziywe ungaxhunyiwe ku-inthanethi.
Izici zokusebenza: Ukuqiniswa kwengcindezi yesistimu kubonakala ngokubambisana kwe-valve yokulawula ingcindezi yegesi kanye ne-pneumatic pressure control valve ekuphumeni kwe-reactor.Izinga lokushisa lilawulwa indlela yokulawula izinga lokushisa ye-PID.Isethi yonke yezinto zokusebenza ingalawulwa yikhabhinethi yokulawula insimu kanye nekhompyutha yezimboni ezikude.Idatha ingarekhodwa futhi amajika angasetshenziswa ekubaleni nasekuhlaziyeni.
Iyiphi inkomba yobuchwepheshe eyinhloko ye-POP Pilot Plant?
Ingcindezi yokusabela: 0.6Mpa;(MAX).
Ingcindezi yokuklama: 0.8MPa.
Ibanga lokulawula izinga lokushisa le-reactor elivuselelwe: 170℃(MAX), ukunemba kokulawula izinga lokushisa: ±0.5℃.
Ibanga lokulawula izinga lokushisa le-Tube reactor: 160 ℃ (MAX), ukunemba kokulawula izinga lokushisa: ±0.5℃.
Ukugeleza okujwayelekile kokusebenza kwephampu yemitha kungu-200-1200g/h.
Izimo zenqubo ye-alamu:
1.I-alamu uma izinga lokushisa lokuhlola lingu-≤85℃.
2. I-alamu uma izinga lokushisa lokuhlola lingu-≥170℃.
3. I-alamu lapho ingcindezi yokuhlola yokusebenza ingu-≥0.55MPa.

Isistimu yokusabela ye-nitrile latex yokuhlola
Inqubo Eyisisekelo I-Butadiene ethangini lempahla eluhlaza ilungiswa kusenesikhathi.Ekuqaleni kokuhlolwa, isistimu iyacocwa futhi ifakwe i-nitrogen ukuze kuqinisekiswe ukuthi lonke uhlelo alunawo umoya-mpilo futhi alunamanzi.Ilungiselelwe ngezinto ezisetshenziswayo zokusetshenziswa kwesigaba se-liquid ehlukahlukene kanye nabaqalisi namanye ama-agent asizayo ayengezwa ethangini lokulinganisa, bese i-butadiene idluliselwa ku-tank metering.Vula t...

Isistimu yokusabela yeNyiloni yokuhlola
Incazelo Yomkhiqizo I-reactor isekelwa kuhlaka lwe-aluminium alloy.I-reactor yamukela isakhiwo esiphendukile esinesakhiwo esiphusile nezinga eliphakeme lokumiswa.Ingasetshenziselwa ukusabela kwamakhemikhali wezinto ezihlukahlukene ngaphansi kokushisa okuphezulu nokucindezela okukhulu.Ifaneleka ngokukhethekile ukunyakazisa nokusabela kwezinto eziphezulu ze-viscosity.1. Impahla: I-reactor yenziwe kakhulu nge-S...

Isistimu yokusabela ye-polyether yokuhlola
Incazelo Yomkhiqizo Lonke isethi yesistimu yokusabela ihlanganiswe kuhlaka lwensimbi engagqwali.I-valve yokudla ye-PO/EO igxilile ohlakeni ukuze kuvinjelwe ukulinganisa isikali sika-elekthronikhi ukuthi singathinteki phakathi nokusebenza.Isistimu yokusabela ixhunywe nepayipi lensimbi engagqwali namavalvu enaliti, okulula ukunqanyulwa nokuxhunywa kabusha.Izinga lokushisa lokusebenza, izinga lokugeleza kokuphakelayo, kanye ne-P...

Uhlelo lokuhlola lwe-Catalyst
Lolu hlelo lusetshenziselwa ikakhulukazi ukuhlolwa kokusebenza kwe-palladium catalyst ekuphenduleni kwe-hydrogenation kanye nokuhlolwa kokuhlola kwezimo zenqubo.Inqubo eyisisekelo: Uhlelo luhlinzeka ngamagesi amabili, i-hydrogen ne-nitrogen, elawulwa ngokulandelana ngesilawuli sokucindezela.I-hydrogen ibalwa ngamamitha futhi yondliwe isilawuli sokugeleza kwenqwaba, futhi i-nitrogen ibalwa futhi yondliwe nge-rotameter, bese idluliselwa ku-reactor.Ukusabela okuqhubekayo kwenziwa ngaphansi...
