DMF Solvent Recovery Plant
Txheej txheem qhia luv luv
Tom qab DMF hnyav los ntawm cov txheej txheem ntau lawm yog preheated, nws nkag mus rau hauv lub cev qhuav dej. Lub dehydrating kem yog muab cov cua sov los ntawm cov chav nyob rau sab saum toj ntawm lub rectification kem. Lub DMF nyob rau hauv kem tank yog concentrated thiab pumped mus rau hauv lub evaporation tank los ntawm lub tso tawm twj tso kua mis. Tom qab cov khib nyiab pov tseg hauv lub evaporation tank yog rhuab los ntawm lub tshuab cua sov, lub vapor theem nkag mus rau hauv lub rectification kem rau rectification, thiab ib feem ntawm cov dej yog zoo tu qab tso thiab rov qab mus rau lub evaporation tank nrog DMF rau re-evaporation. DMF yog muab rho tawm los ntawm kab distillation thiab ua tiav hauv kab deacidification. Lub DMF uas ua los ntawm sab kab ntawm kab deacidification yog txias thiab pub rau hauv DMF cov khoom tiav tank.
Tom qab txias, cov dej nyob rau sab saum toj ntawm kem nkag mus rau hauv cov kav dej phwj dej los yog nkag mus rau hauv qhov kev kho dej thiab rov qab mus rau cov kab ntau lawm rau kev siv.
Cov cuab yeej yog ua los ntawm cov roj thermal ua qhov cua sov, thiab cov dej ntws los ua qhov chaw txias ntawm cov khoom siv rov qab los. Cov dej circulating yog muab los ntawm lub twj tso kua mis circulating, thiab rov qab mus rau lub circulating pas dej ua ke tom qab tshav kub exchanger, thiab yog txias los ntawm lub txias ntauwd.

Cov khoom siv cim
Rectifying system ntawm DMF hnyav
Lub tshuab rectifying txais lub tshuab nqus tsev concentration kem thiab rectifying kem, cov txheej txheem tseem ceeb yog thawj concentration kem (T101), thib ob concentration kem (T102) thiab rectifying kem (T103), lub systemic zog txuag yog pom tseeb. Lub system yog ib qho ntawm cov txheej txheem tshiab tam sim no. Muaj cov qauv muab tub lim kom txo tau lub siab poob thiab ua haujlwm kub.
Vaporization system
Vertical evaporator thiab yuam kev ncig yog saws nyob rau hauv vaporization system, lub kaw lus muaj qhov zoo ntawm kev ntxuav yooj yim, ua haujlwm yooj yim thiab lub sijhawm ua haujlwm ntev.
DMF De-acidification System
Lub DMF deacidification system txais yuav gaseous theem tawm, uas daws cov teeb meem ntawm cov txheej txheem ntev thiab siab disintegrate ntawm DMF rau cov kua theem, lub caij no txo cov cua kub noj ntawm 300,000kcal. nws yog tsawg zog noj thiab siab rov qab tus nqi.
Residue Vaporization System
Lub kaw lus tshwj xeeb yog tsim los kho cov kua residue. Cov kua residue ncaj qha tawm mus rau lub tshuab ziab khaub ncaws seem ntawm lub cev, tom qab ziab, thiab tom qab ntawd tso tawm, uas tuaj yeem max. rov qab DMF hauv qhov seem. Nws txhim kho DMF tus nqi rov qab thiab lub sijhawm no txo cov pa phem.
