Ukuqhathaniswa kwezinzuzo kanye nokungalungi kokusebenzisa i-sodium carbonate noma i-sodium hydroxide ukulungisa inani le-pH lamanzi okuphakelwa kwebhoyila

1, amanzi okuphakelayo ebhoyila ukulungisa inani le-pH lesizathu

Namuhla, ama-boiler amaningi eShayina asebenzisa amanzi angenawo amaminerali ...

2, isimiso esiyisisekelo sokwengeza i-sodium carbonate emanzini okuphakelayo ebhoyila ukulungisa inani le-pH

I-sodium carbonate yaziwa kakhulu ngokuthi i-soda, i-soda ash, i-soda ash, i-washing alkali, ehlukaniswe njengosawoti, hhayi i-alkali, ifomula yamakhemikhali i-Na2CO3, ngaphansi kwezimo ezijwayelekile zempuphu emhlophe noma usawoti ocolekile. Isimiso esiyisisekelo sokwengeza i-sodium carbonate emanzini okuphakelayo e-boiler ukulungisa inani le-pH ukusebenzisa i-sodium carbonate ukuncibilika emanzini futhi kube yi-alkaline, okunganciphisa i-carbon dioxide emanzini okuphakelayo ane-acid futhi kuxazulule ukugqwala kwamanzi athambile e-acid noma amanzi anosawoti e-boiler nasepayipini. I-sodium carbonate iyi-electrolyte ebuthakathaka, encibilikiswe emanzini ukuze yakhe isisombululo se-buffer se-sodium carbonate ne-sodium bicarbonate, kukhona ibhalansi ye-electrolytic esixazululweni, ngokusetshenziswa kwe-electrolytic hydroxide, ibhalansi izoqhubeka iqhubekela kwesokudla, ngakho-ke i-pH ekhona ekuphenduleni ayishintshi kakhulu.

Inqubo ye-hydrolysis eyinhloko ye-sodium carbonate:

I-Na2CO3 Sodium carbonate +H2O amanzi = I-NaHCO3 sodium bicarbonate +NaOH sodium hydroxide

Inqubo ye-hydrolysis yesibili ye-sodium carbonate:

I-NaHCO3 sodium bicarbonate +H2O amanzi =H2CO3 carbonic acid +NaOH sodium hydroxide

I-Sodium carbonate equation eyinhloko ye-hydrolyzed ion:

(CO3) 2-carbonic acid +H2O amanzi =HCO3- bicarbonate +OH- hydroxide

I-Sodium carbonate secondary hydrolyzed ion equation:

I-HCO3- i-bicarbonate + amanzi e-H2O = i-H2CO3 i-carbonic acid + i-OH- i-hydroxide

3, isimiso esiyisisekelo sokwengeza i-sodium hydroxide emanzini ebhoyila ukulungisa inani le-pH

I-sodium hydroxide ibizwa nangokuthi i-caustic soda, i-caustic soda, i-caustic soda, i-caustic soda, ngokuvamile i-white flake, ifomula yamakhemikhali i-NaOH, i-sodium hydroxide ine-alkaline enamandla, igqwala kakhulu.

I-ionization equation ye-sodium hydroxide: NaOH=Na++OH-

Ukwengeza i-sodium hydroxide emanzini ebhoyila kungazinzisa ifilimu evikelayo ebusweni bensimbi, kuthuthukise inani le-pH lamanzi okuphakelwa kwebhoyila kanye namanzi esitofini, ukuze kuxazululwe ukugqwala kwamanzi athambile ane-asidi noma amanzi angenawo amaminerali kubhoyila kanye nepayipi, futhi kuvikelwe imishini yensimbi ekugqwaleni.

4. Izinzuzo kanye nokungalungi kokusebenzisa i-sodium carbonate noma i-sodium hydroxide ukulungisa inani le-pH lamanzi okuphakelwa kwebhoyila kuyaqhathaniswa

4.1 Ijubane lokuphakamisa inani le-pH nge-sodium carbonate kanye ne-sodium hydroxide yamanzi okuphakelwa kwebhoyila kanye nesikhathi sokugcina umphumela wokusetshenziswa kuhlukile

Ijubane lokufaka i-sodium carbonate emanzini ebhoyila ukuze kwandiswe inani le-pH lihamba kancane kunele-sodium hydroxide. Ngenxa yokuthi i-sodium carbonate ikhiqiza isisombululo se-buffer, inokuguquguquka okuncane futhi izinzile futhi kulula ukuyilungisa. Kodwa-ke, ububanzi bokulungiswa kwe-pH bunqunyelwe. Uma kulungiswa inani elifanayo le-pH, inani le-sodium carbonate lizoba likhulu kunele-sodium hydroxide. Umphumela wokusetshenziswa ugcinwa isikhathi eside, futhi i-pH yamanzi akulula ukuyilahla.

I-sodium hydroxide iyisisekelo esiqinile kanye ne-electrolyte eqinile, i-sodium hydroxide yokulungisa inani le-pH lokuguquguquka inkulu, i-sodium hydroxide ngemva kokufaka i-pH yamanzi kulula ukuyikhulisa, ukulungisa inani le-pH ngokushesha nangokuqondile, kodwa futhi kulula ukuyigumbuqela ayikwazi ukubeka okuningi kakhulu, uma kuqhathaniswa ne-sodium carbonate ukwengeza okuncane kakhulu kungafinyelela izidingo zenkomba ye-pH, okungukuthi, yize inani le-pH le-sodium hydroxide lenyukile, Kodwa-ke, inani le-sodium hydroxide engeziwe alilikhulu, okungukuthi, ikhono lamanzi lokunciphisa i-asidi yeqembu le-hydroxide alikhuli kakhulu, i-pH izokwehla maduze.

4.2 Umonakalo obangelwa ukwengezwa ngokweqile kwe-sodium carbonate kanye ne-sodium hydroxide ukwandisa inani le-pH lamanzi okuphakelwa kwebhoyila uhlukile

Ukwengeza i-sodium carbonate eningi kakhulu emanzini ebhoyila ukuze kulungiswe inani le-pH kuzokwandisa okuqukethwe usawoti emanzini ebhodweni kanye nokuqhuba komoya; Kunezinhlobo eziningi zama-ion e-bicarbonate emanzini ebhodweni, futhi ama-ion e-bicarbonate abola kalula abe yi-carbon dioxide uma eshiswa. I-CO2 ingena ku-heat exchanger bese ifaka amanzi e-condensate ngomusi. I-Sodium carbonate ayikwazi nje ukulungisa inani le-pH lamanzi abuyayo e-steam kanye ne-steam condensate, kodwa futhi inciphisa inani le-pH lomusi kanye ne-condensate, igqwalise i-heat exchanger kanye ne-condensate pipeline. Isizathu sokuthi ama-ion ensimbi emanzini abuyayo e-steam condensate adlula umbala ojwayelekile ophuzi noma obomvu.

Ukwengeza i-sodium hydroxide eningi kakhulu emanzini esithandweni ukuze kulungiswe inani le-pH kuzokwenza ukuthi amanzi ebhodweni abe phezulu kakhulu, bese kuvela amanzi ne-soda. Inani le-sodium hydroxide akulula ukulilawula, futhi i-NaOH ekhululekile ngokweqile izobangela i-alkalinity enkulu, kanti ukuqhekeka kwe-alkali nakho kuzobangela ukugqwala emishinini. Umbhali ubone ithangi lepulasitiki eliqiniswe nge-fiber yengilazi eligcwele ama-patches endaweni yomsebenzisi, elagqwala futhi labhoboka ngenxa yokusetshenziswa kwe-sodium hydroxide ukulawula inani le-pH le-debrine. I-sodium hydroxide ayikwazi ukulungisa inani le-pH lamanzi abuyayo e-steam kanye ne-steam condensation, futhi ayikwazi ukulawula ukugqwala kwemishini yesistimu yamanzi abuyayo e-steam kanye ne-steam condensation kanye nenethiwekhi yamapayipi.

4.3 Ukuphepha kwe-sodium carbonate kanye ne-sodium hydroxide esetshenziswa emanzini okuphakelwa kwebhoyila ukuphakamisa inani le-pH kuhlukile

I-sodium carbonate ithambile, ingeyokudla okusesigabeni sayo, ivuselela kancane, igqwala kancane, ingasetshenziswa ngesandla, futhi idinga ukugqoka amagilavu ​​isikhathi eside.

I-sodium hydroxide iyinto eyingozi, iyagqwala, futhi isixazululo sayo noma uthuli olufafazwe esikhumbeni, ikakhulukazi olwelwesini lwamafinyila, lungadala amabala athambile, futhi lungangena ezicutshini ezijulile. Ukusha kushiya isilonda. Ukushaza esweni, akugcini nje ngokulimaza i-cornea, kodwa futhi kulimaza nezicubu ezijulile zeso. Ngakho-ke, opharetha kufanele afake amafutha angathathi hlangothi futhi angangenisi amanzi esikhumbeni, futhi kumele agqoke izingubo zomsebenzi, imaski, izibuko zokuzivikela, amagilavu ​​​​erabha, ama-apron erabha, amabhuzu erabha amade kanye nezinye izinto zokuvikela abasebenzi ukuze enze umsebenzi omuhle wokuvikela umuntu siqu.

Kunezimo zokusetshenziswa nokuhlolwa ezibonisa ukuthi: I-Sodium hydroxide kanye ne-sodium carbonate zisetshenziswa ngokushintshana, noma zixutshwe, umnotho kanye nomphumela wazo kungcono kunokusebenzisa isilawuli esithile se-pH kuphela. Lapho inani le-pH lamanzi okuphakelwa kwebhoyila litholakala liphansi kakhulu, i-sodium hydroxide ethile ingafakwa ngokufanele ukuze kwandiswe ngokushesha inani le-pH. Ngemva kokuba i-sodium hydroxide incibilike ngokuphelele, i-sodium carbonate ethile ingafakwa ukuze kukhuliswe i-carbonate emanzini. Lokhu kungenza kube lula ukwehla kwenani le-pH lamanzi okuphakelwa; Ngenxa yokuthi inani le-sodium carbonate lingafakwa kakhulu, ikhono lokugcina ama-carbonate emanzini liningi, ngakho-ke ngokuvamile i-sodium carbonate ingasetshenziswa ukugcina inani le-pH lamanzi kanye namanzi asebhodweni, kuphela uma inani le-pH lamanzi liphansi kakhulu, umbhali uncoma ukusetshenziswa kwe-sodium hydroxide ukuze kwandiswe ngokushesha inani le-pH, ukuze kokubili kuhlanganiswe ngokushintshana, kokubili ngomnotho nangomphumela omuhle.
