Oomatshini bokwenza isichumiso seUrea

Oomatshini bokwenza isichumiso se-Urea badlala indima ebalulekileyo ekuvelisweni kwesichumiso se-urea, isichumiso esisetyenziswa ngokubanzi esekwe kwinitrogen kwezolimo.Aba matshini bobuchwephesha benzelwe ukuguqula ngokufanelekileyo imathiriyeli ekrwada ibe yi-urea ekumgangatho ophezulu ngokusebenzisa uthotho lweenkqubo zemichiza.

Ukubaluleka kwesichumiso seUrea:
Isichumiso se-Urea sixatyiswa kakhulu kwezolimo ngenxa yesiqulatho saso senitrogen eninzi, eyimfuneko ekukhuthazeni ukukhula kwezityalo kunye nesivuno sezityalo.Ibonelela ngomthombo ofumaneka lula wenitrogen, obalulekileyo ekuphuhliseni amagqabi, izikhondo, kunye nezinye izihlunu zezityalo.Isichumiso se-Urea sinceda ekuphuculeni ukuchuma komhlaba, siphucula ukufunxwa kwezondlo zizityalo, kwaye sinegalelo ekwandeni kwemveliso yezolimo.

Amacandelo angundoqo oomatshini bokwenza isichumiso se-Urea:

I-Reactor: I-reactor licandelo elingundoqo kumatshini wokwenza isichumiso se-urea.Iququzelela ukusabela phakathi kwe-ammonia kunye ne-carbon dioxide phantsi kobushushu obulawulwayo kunye neemeko zoxinzelelo.Le ndlela yokusabela, eyaziwa ngokuba yinkqubo ye-urea synthesis, ivelisa urea njengeyona mveliso iphambili.

I-Scrubber: I-scrubber inoxanduva lokususa ukungcola kunye neemveliso ezingafunekiyo ezivela kwinkqubo ye-urea synthesis.Inceda ukuqinisekisa ukucoceka kunye nomgangatho wemveliso yokugqibela yesichumiso se-urea.I-scrubber isebenzisa iindlela ezahlukeneyo, ezifana nokuhlamba, ukuhluza, okanye ukufunxa, ukwahlula kunye nokususa ukungcola ngokufanelekileyo.

I-Granulation System: Inkqubo ye-granulation inoxanduva lokuguqula i-urea yamanzi ibe yi-granular okanye iifom ze-prilled, ezilungele ngakumbi ukugcinwa, ukuthuthwa, kunye nokusetyenziswa.Le nkqubo ibandakanya iinkqubo ezinje ngokutshiza i-urea yolwelo ibe ngamathontsi, ukuqina, kunye nokulinganisa ubungakanani obufunekayo begranule.

Izixhobo zokugquma kunye nezokomisa: Izixhobo zokugquma kunye nezomisa zisetyenziselwa ukuphucula iimpawu ezibonakalayo zesichumisi se-urea, njengokuphucula ukuchasana nomswakama kunye ne-caking.Iinkqubo zokugquma zibandakanya ukusebenzisa umgca omncinci wezinto eziphathekayo, ezifana neepolymers okanye isulfure, kwi-granules ye-urea.Izixhobo zokomisa ziqinisekisa ukukhutshwa komswakama ogqithiseleyo kwi-urea edibeneyo, ukwandisa ukugcinwa kwayo kunye neempawu zokuphatha.

Ukuphucula iMveliso yezichumiso:
Oomatshini bokwenza isichumiso se-Urea badlala indima ebalulekileyo ekwandiseni imveliso yesichumiso ngeendlela ezininzi:

Ukusebenza okuphezulu: Aba matshini benzelwe ukusebenza ngokufanelekileyo, ukunciphisa ukusetyenziswa kwamandla kunye nokwandisa imveliso yemveliso.Ubuchwephesha obuphezulu kunye nokulungiswa kwenkqubo kuqinisekisa amazinga aphezulu okuguqulwa, ukunciphisa inkunkuma kunye nokwandisa ukusetyenziswa kwezinto eziluhlaza.

Ukulawulwa koBulunga: Oomatshini bokwenza isichumiso se-Urea babandakanya iinkqubo zolawulo ezichanekileyo zokubeka iliso kunye nokugcina iimeko ezifanelekileyo zokusebenza ngexesha lenkqubo yokuvelisa.Oku kuqinisekisa umgangatho wemveliso ongaguqukiyo kunye nokucoceka, ukuhlangabezana nemigangatho yoshishino efunekayo kunye nokulindelwe ngabathengi.

Ukwenziwa ngokwezifiso kunye nokukaleka: Oomatshini bokwenza isichumiso se-Urea babonelela ngokuguquguquka kwimveliso, evumela ukulungelelaniswa kokwenziwa kwesichumiso kunye nobukhulu begranule ukuhlangabezana neemfuno ezithile zesityalo kunye nomhlaba.Ngaphaya koko, aba matshini bayilelwe ukuba balinganiseke, bamkele amandla okuvelisa okwahlukeneyo ngokwemfuno yentengiso.

Inkqubo yoKhuseleko: Iimpawu zokhuseleko kunye neeprothokholi zidityanisiwe kuyilo lomatshini wokwenza isichumiso se-urea ukuqinisekisa indawo yokusebenza ekhuselekileyo.Oku kubandakanya imilinganiselo yokulawula iikhemikhali ezinobungozi, ukuthintela ukukhutshwa ngengozi, kunye nokunciphisa iingozi ezinokubakho ezinxulumene nokusebenza koxinzelelo oluphezulu.

Oomatshini bokwenza isichumiso se-Urea badlala indima ebalulekileyo ekuvelisweni kwesichumiso se-urea esikumgangatho ophezulu, ukuxhasa imveliso yezolimo kunye neendlela ezizinzileyo zokulima.Amacandelo aphambili, anje nge-reactors, i-scrubbers, iinkqubo zegranulation, i-coating, kunye nezixhobo zokomisa, zisebenza ngokubambisana ukuguqula izinto eziluhlaza zibe yimveliso ephezulu yesichumiso se-urea.
