Polymer polyols (POP) reaction system
Mafotokozedwe Akatundu
Dongosolo ili ndi oyenera mosalekeza anachita zinthu gasi-zamadzimadzi gawo pansi pa kutentha ndi kuthamanga.Amagwiritsidwa ntchito makamaka pakuyesa kuyesa kwa machitidwe a POP.
Basic process: madoko awiri amaperekedwa kwa mpweya.Doko limodzi ndi nayitrogeni kuti ayeretse chitetezo;ina ndi mpweya monga gwero la mphamvu ya vavu ya pneumatic.
The zinthu zamadzimadzi ndi molondola metered ndi sikelo pakompyuta ndi kudyetsedwa mu dongosolo ndi zonse kusinthasintha mpope.
Zomwe zimachitikira poyamba mu riyakitala yogwedezeka pansi pa kutentha ndi kupanikizika kwa wosuta, ndiye kuti zimatulutsidwa kwa riyakitala ya tubular kuti ipitirize kuchita.Zogulitsa pambuyo pakuchitapo zimafupikitsidwa mu condenser ndikusonkhanitsidwa kuti ziwunikidwe popanda intaneti.
Makhalidwe ogwirira ntchito: Kukhazikika kwadongosolo kwadongosolo kumazindikirika ndi mgwirizano wa valavu yowongolera mpweya wamagetsi ndi valavu ya pneumatic pressure control at outlet of reactor.Kutentha kumayendetsedwa ndi njira yoyendetsera kutentha kwa PID.Zida zonse zimatha kuyendetsedwa ndi kabati yoyang'anira munda komanso makompyuta akutali.Deta ikhoza kujambulidwa ndipo ma curve angagwiritsidwe ntchito kuwerengera ndi kusanthula.
Chizindikiro chachikulu chaukadaulo cha POP Pilot Plant ndi chiyani?
Kuthamanga kwa zochita: 0.6Mpa;(MAX).
Kupanikizika kwa mapangidwe: 0.8MPa.
Kuwongolera kutentha kwa riyakitala: 170 ℃(MAX), kuwongolera kutentha kulondola: ± 0.5 ℃.
chubu riyakitala kulamulira kutentha osiyanasiyana: 160 ℃ (MAX), kutentha ulamuliro molondola: ± 0.5 ℃.
Kuthamanga kwabwino kwa mpope wa metering ndi 200-1200g/h.
Zoyenera kuchita ma alarm:
1.Alamu pamene kuyesa ntchito kutentha ndi ≤85 ℃.
2. Alamu pamene kuyesa ntchito kutentha ndi ≥170 ℃.
3. Alamu pamene kukakamiza koyeserera ndi ≥0.55MPa.
