Kwimeko yendawo yanamhlanje, iingxaki zogutyulo olubangelwa kuphuhliso lwamashishini ziye zaphathwa ngokufanelekileyo ekhaya nakwamanye amazwe. Ukuthetha oku, kufuneka sikhankanye isimo se-decolorizing flocculants kunyango lwamanzi. Ngokusisiseko, ilindle eliveliswa ngamashishini amaninzi kufuneka lisebenzise i-flocculants esusa umbala. I-Yixing Cleanwater iya kukwazisa kulwazi olufanelekileyo kunye nokusetyenziswa kwiinkalo ezahlukeneyo.
Iiflocculants ezahlukeneyo zepolymer decolorizing zisetyenziswa kakhulu kwindawo yamanzi amashishini kunye nokucocwa kogutyulo phesheya, phakathi kwayo iPolyacrylamide (PAM) lolona hlobo luphambili lwe-decolorizing flocculant. Xa kuthelekiswa neeflocculants zetyuwa zemveli, iPAM, njengohlobo olutsha lokucoca amanzi, ineengenelo ezininzi: ilula kwaye kulula ukuyisebenzisa, isiphumo se-flocculation siphindaphindwa ngokuphindwe kaninzi kune-flocculants yetyuwa yemveli; ukuntywila okukhawulezayo kunye nesantya sentlenga, ukusebenza kakuhle koludaka lokukhupha amanzi; impembelelo ekhethekileyo yonyango kugutyulo oluthile; izixhobo ezilula ezifunekayo, unyawo oluncinci; iindleko eziphantsi zonyango; amanzi amdaka anokuphinda asetyenziswe kwaye asetyenziswe kwakhona, njl.
Ukusetyenziswa kwePAM decolorizing flocculant kwimihlaba eyahlukeneyo yesicelo:
1. Isicelo kwishishini lokwenza iphepha
Ukusebenzisa i-molecular weight PAM njenge-flocculant decolorizing kunokunyusa izinga lemvula yee-pigments kunye nezinye izinto kumanzi amhlophe kunye nokunciphisa ukulahleka kwazo. Ukongeza i-0.25 ~ 0.5% ye-PAM kwi-pulp inokunyusa izinga le-sedimentation ye-pulp ngamaxesha angama-40 ~ 80, ukunciphisa umxholo oqinileyo kumanzi amhlophe malunga ne-66%, ukwandisa umlotha wephepha, ukwandisa izinga lokugcinwa kwee-pigments ezifana nodongwe olumhlophe nge-8 ~ 18%, kwaye ugcine i-20kg ye-pulp ngetoni yephepha. Ngaphezu koko, emva kokusebenzisa i-PAM, i-turbidity yamanzi amhlophe iyancipha kakhulu, inciphisa ukungcoliseka kwendalo. Umzekelo, izinto eziqinileyo ezinqunyanyisiweyo zamanzi amdaka amdaka amhlophe ane pH=6.8 yi 3000ppm. Emva kokunyangwa nge-PAM nge-hydrolysis degree ye-5 ~ 10%, ubunzima be-molecular ye-5.5 ~ 10 yezigidi, kunye ne-500ppm ye-aluminium sulfate, amanzi amhlophe anokuguqulwa abe ngumbane ongenambala kunye obala, kwaye i-solids emisiwe iyancipha ibe ngaphantsi kwe-50ppm.
2. Ukusetyenziswa kwe-decolorizing flocculants kunyango lwamanzi
①Anti-scaling kunye nokwehla
Kumanzi amashishini kunye nokucocwa kogutyulo, amanzi akrwada kufuneka aqale acaciswe. I-PAM decolorizing flocculants kunye ne-inorganic coagulants zihlala zisetyenziswa ngokudibeneyo, ezinokunciphisa kakhulu ukusetyenziswa kwe-inorganic coagulants, ukuphepha ukuvaleka kwezixhobo kunye nokubola ngenxa yokusetyenziswa ngokugqithiseleyo kwe-inorganic coagulants, kunye nokuthintela ukubunjwa kwesikali. Iingxenye ze-37.5 ze-PAM ezinobunzima be-molecular ngaphantsi kwe-1 yezigidi kunye neengxenye ze-50 ze-sodium tripolyphosphate zisetyenziselwa ukwenza i-scale inhibitor, enokuthintela ngokusisiseko umlinganiselo we-heat exchangers.
②Ukunyangwa kwamanzi amdaka emizi-mveliso
3. Ukusetyenziswa kwe-decolorizing flocculants kunyango lwamanzi amdaka kwishishini leswekile
Ijusi yommoba ekhutshwa kumatshini wokushicilela yimizi-mveliso yeswekile idla ngokuba nenkunkuma kwaye nokwakheka kwawo kuntsonkothile. Ukuze ufumane incindi ecocekileyo yommoba, kufuneka kongezwe izinto zokucacisa imichiza. Ngaphambili, i-inorganic decolorizing flocculants yayidla ngokusetyenziswa, kodwa ngophuhliso lweshishini leswekile, i-inorganic decolorizing flocculants ayinakukwazi ukuhlangabezana neemfuno zemveliso. Kwiminyaka yakutshanje, ukusetyenziswa kwe-PAM kwishishini leswekile kunokunyusa izinga le-sedimentation ngamaxesha angama-20.
Isishwankathelo, xa sikhetha i-polyacrylamide PAM decolorization flocculant ngokweyona meko, kufuneka siyikhethe ngokweemeko ezahlukeneyo zesicelo kunye neemeko. Ke ngoko, ukhetho lwepolyacrylamide lubaluleke kakhulu.
