Cov nroj tsuag tsim phosphate hauv tsev, hauv cov tshuaj tiv thaiv, pom, tail gas ntxuav, acid cia thiab lwm yam, nrog rau cov hauv qab no cov yam ntxwv tseem ceeb:
(1) integrated tshuaj tiv thaiv / digestion tank
Hauv tsev tus kheej tsim phosphate cog, phosphate thiab sulfuric acid cov txheej txheem tshuaj tiv thaiv thiab cov txheej txheem slurry digestion hauv tib cov khoom kom ua tiav, uas yog, Phosphoric Acid Cog cov tshuaj tiv thaiv tank thiab digestion tank rau hauv ib qho. Lub tank lub cev yog pob zeb ua qauv, lined nrog roj hmab thiab carbon cib. Cov qauv phab ntsa sab hauv tuaj yeem tiv thaiv cov phab ntsa sab hauv cov pa roj carbon cij hauv ob sab phlu los ntawm kev poob.
Reaction / digestion tank nrog multi-chamber qauv, txhua chav nruab nrog ib tug stirrer. Tov khoom nrog cov qauv tsim tshwj xeeb ntawm paddle, thaum ua kom muaj kev sib xyaw ua ke, tuaj yeem txo qis kev siv hluav taws xob thiab txuag hluav taws xob.
Raw sulfuric acid nyob rau hauv cov tshuaj tiv thaiv / digestion tank nyob rau hauv lub multi-chav multi-point kom zoo disperse cov khoom, Phosphoric Acid Plant txo lub zos concentration, txhim kho cov phosphogypsum crystallization.
(2) Recycling lub tshav kub ntawm cov tshuaj tiv thaiv slurry
Kev ua kom txias ntawm cov tshuaj tiv thaiv slurry yog ua tiav los ntawm kev ntws loj ntawm sab nraud ncig. Cov pa roj vaporized nyob rau hauv lub flash chamber yog pre-condensed rau hauv pre-condenser, feem ntau pre-condensed los ntawm lub pas dej ua ke rov qab los ntawm phosphogypsum slag kom rov qab tau ib feem ntawm lub tshav kub. Cov dej rhuab yog ntxuav raws li lub ncuav mog qab zib lim. Qhov no yuav txuag tau chav siv thiab rov ua dua dej.
Reactive slurry txias nrog loj txaus sab nraum lub voj voog, tuaj yeem tswj cov tshuaj tiv thaiv slurry kub, txuag lub zog, Phosphoric Acid Plant txo cov khoom siv thiab cov raj xa dej fouling, txuas ntxiv lub voj voog khiav haujlwm.
(3) cov txheej txheem filtration yooj yim
Domestic phosphate cog, lub ntsiab siv ntawm domestic ntau lawm cog tilting phaj lim thiab turntable lim. Txawm hais tias hom lim siv, koj tuaj yeem teeb tsa cov txheej txheem tsim khoom yooj yim.
Filter acid twj tso kua mis tuaj yeem siv lub twj tso kua mis tus kheej lossis kev tswj ntau zaus, yog li tsis tas yuav lim lub tank, cov txheej txheem yog yooj yim thiab du, tuaj yeem txo kev nqis peev, txo cov txheej txheem scaling, txuas ntxiv lub voj voog tu.
Lim lub tshuab nqus tsev vacuum, los ntawm cov raj xa dej ua ntej sib cais, Phosphoric Acid Plant thiab tom qab ntawd mus rau hauv qhov sib cais thiab cov condenser, txhawm rau txhim kho qhov kev sib cais, kom ntseeg tau tias qhov zoo ntawm cov dej txias.
(4) Cov txheej txheem ntxuav cov tail gas
Cov txheej txheem ntub dej phosphoric acid cog tso tawm cov txheej txheem ntxuav, muaj kab rov tav cross-flow ntim txaj ntxhua thiab ntsug khoob ntauwd ntxuav ob txheej txheem.
Ob hom kev ntxuav, txhua tus muaj nws tus yam ntxwv. Cov txheej txheem ntawm kev xaiv, feem ntau yog nyob ntawm qhov zoo ntawm raw cov ntaub ntawv phosphate. Yog tias cov khoom siv raw ntawm phosphate pob zeb nyob rau hauv cov ntsiab lus siab ntawm ntau lawm yog ib qho yooj yim los tsim silicone tshwm sim los ntawm qhov system blockage, Phosphoric Acid Plant nws raug pom zoo kom siv ntsug ntauwd tu txheej txheem.
Feem ntau cov lim slurry pub cheeb tsam thiab ib qho ntawm cov pa tso pa tawm kuj raug coj mus rau hauv cov pa tso pa ntxhua khaub ncaws rau kev ntxuav kom txhim kho lub khw hauv tsev ua haujlwm.
(5) ywj siab tu Circuit Court
Cov txheej txheem ntub dej phosphoric acid cog cov tshuaj tiv thaiv thiab pom seem, feem ntau teeb tsa kev tu tshwj xeeb, teeb tsa ~ 5% H2SO4 ua cov tshuaj ntxuav. Kev tu vaj huam sib luag ntawm cov txheej txheem tsim, txhawm rau kom ua tiav qhov siab tshaj plaws ntawm kev ntxuav cov phosphate pipeline feem ntau rau lub hom phiaj.
Tom qab lub kaw lus tau ntxuav, cov tshuaj ntxuav tuaj yeem maj mam rov qab mus rau cov tshuaj tiv thaiv rau kev rov ua dua tshiab.
(6) Secondary fluorine absorption
Phosphoric acid enrichment device ntawm fluorine absorption siv ob fluorine absorption, txhim kho tus nqi nqus ntawm fluorine kom ntseeg tau tias fluorosilicic acid P2O5 cov ntsiab lus<>
(7) ib tug loj heev acid cia system
Txhawm rau txhawm rau txhim kho qhov zoo ntawm dilute phosphoric acid thiab concentrated phosphoric acid nkag mus rau cov txheej txheem tom ntej lossis cov nroj tsuag hauv qab, dilute phosphoric acid thiab concentrated phosphoric acid feem ntau yog siv hauv" kev laus + clarification" txheej txheem.
(8) Cov khoom siv loj dej sib npaug thiab siv
Phosphoric acid cog, feem ntau phosphoric acid ntau lawm cog, phosphoric acid circulating dej chaw nres tsheb, phosphogypsum slag teb raws li ib tug tag nrho los xav txog, kom ua tiav tag nrho cov dej tshuav nyiaj li cas, Phosphoric Acid Plant kev siv phosphoric acid circulating dej chaw nres tsheb ib txwm tso dej thiab phosphogypsum slag. teb rov qab dej, qib siab tshaj plaws Txo cov dej tshiab, txo cov nqi khiav haujlwm.
Tam sim no, tus nqi ntawm phosphate pob zeb tau nce siab heev. Tus nqi ntawm phosphoric acid thiab ammonium phosphate kuj tau nce ntau heev. Nws muaj kev sib tw muaj zog hauv zej zog thoob ntiaj teb. Kev tsim cov phosphate cog yuav tsum tau them sai sai rau kev txhim kho thiab kev siv cov phosphate qib qis. Ntawm qhov tod tes, cov cog tshiab phosphate chiv cog hauv kev siv cov khoom siv phosphate chiv los yog cov khoom lag luam zoo tsis muaj qhov tshwj xeeb, yuav tsum xav txog kev siv phosphate pob zeb adaptability ntawm cov txheej txheem ntau lawm, xws li kev siv ob txheej txheem dej. Ntawm qhov tod tes, nws yuav tsum ntxiv dag zog rau qib nruab nrab lossis txawm tias qib qis phosphate ntxhia ua cov thev naus laus zis txhim kho thiab siv tau.
