Ukuqhathaniswa kwezinzuzo nobubi bokusebenzisa i-sodium carbonate noma i-sodium hydroxide ukulungisa inani le-ph kwamanzi okuphakelayo we-boiler

1, Amanzi okuphakelayo ama-boiler ukuguqula inani le-PH lesizathu

Kulezi zinsuku, ama-boilers amaningi e-china asebenzisa i-reverse osmosis enamanzi e-decineraled amanzi noma i-sodium ion resin ukushintshanisa inani lamanzi athambile aphansi futhi i-acidic ion demin exchange aphansi futhi i-acinosis demin exchanged VALES Ivelu yenani elithambile futhi linokushintshana ngokucophelela kwenani lamanzi athambile ngokuvamile Kuma-boilers namapayipi, ngokuya ngezinhlinzeko ze-National Standard BG / T1576-2008, inani le-PH le-PH Inani lamanzi aphakathi kwe-8,5, ngakho-ke ukuhlinzekwa kwamanzi ama-boiler kudinga ukulungisa inani le-PH.

2, umgomo oyisisekelo wokungeza i-sodium carbonate kumanzi okuphakelayo we-boiler ukuguqula inani le-PH

I-sodium carbonate yaziwa kakhulu ngokuthi i-soda, i-soda ash, u-soda ash, ukugeza i-alkali, ihlukaniswe njengosawoti, i-ormali, ifomula ye-na2co3, ngaphansi kosawoti omhlophe noma usawoti omuhle. Umgomo oyisisekelo wokungeza i-sodium carbonate emanzini okuphakelayo we-boiler ukuguqula inani le-ph ukusebenzisa ama-sodium carbonate emanzini noma amanzi anosawoti ku-boiler nepayipi. I-Sodium Carbonate iyi-electrolyte ebuthakathaka, echithwe emanzini ukuze wakhe isixazululo se-buffer ye-sodium carbonate kanye ne-sodium bicarbonate, ngokusetshenziswa kwe-electrolytic hydroxide, ngakho-ke ibhalansi izoqhubeka nokuya ngakwesokunene, ngakho-ke i-PH akhona ekuphenduleni ayiguquli okuningi.

Inqubo ye-sodium carbonate eyisisekelo ye-hydrolysis inqubo:

I-NA2CO3 sodium carbonate + h2o amanzi = nahco3 sodium bicarbonate + Naoh Sodium Hydroxide

Inqubo ye-sodium carbonate yesibili ye-hydrolysis:

Nahco3 sodium bicarbonate + h2o amanzi = h2co3 carbonic acid + Naoh Sodium Hydroxide

I-sodium carbonate eyisisekelo ye-hydrolyzed ion equation:

(CO3) 2-CarBonic Acid + H2O Amanzi = I-HCO3- Vicarbonate + Ohroxide

I-Sodium Carbonate Seal Hydrolyzed Ion Equation:

I-HCO3- Bicarbonate + H2O Water = H2CO3 Carboc Acid + Oh- hydroxide

I-3, umgomo oyisisekelo wokungeza i-sodium hydroxide emanzini ama-boiler ukuguqula inani le-PH

I-Sodium Hydroxide ibizwa nangokuthi i-caustic soda, i-caustic soda, i-caustic soda, imvamisa i-flake emhlophe, ifomula yamakhemikhali naoh, i-sooh ye-sooh, i-sodium hydroxide ine-alkali eqinile, esebenza ngokweqile.

Ionization equation ye-sodium hydroxide: naoh = na ++ oh-

Ukungezwa i-sodium hydroxide emanzini ama-boiler angazinza ifilimu evikelayo ebusweni bensimbi, ukuxazulula i-aulier feed amanzi noma amanzi e-boiler athambile noma amapayipi e-boiler kanye nepayipi, futhi avikele imishini yensimbi evela ekugcekeni.

I-4. Izinzuzo nokubi kokusebenzisa i-sodium carbonate noma i-sodium hydroxide ukulungisa inani le-PH lamanzi okuphakelayo ama-boiler feed aqhathaniswa

4.1 Ijubane Lokukhulisa Inani le-PH nge-sodium carbonate ne-sodium hydroxide ye-boiler feed amanzi nesikhathi sokugcina umphumela wokusebenzisa ahlukile

Ijubane lokungeza i-sodium carbonate ekunikezelweni kwamanzi e-boiler ukukhulisa inani le-PH lihamba kancane kunaleso se-sodium hydroxide. Ngoba i-sodium carbonate yakha isixazululo se-buffer, inokushintshashintsha okuncane futhi iqinile futhi kulula ukuyilungisa. Kodwa-ke, uhla lokulungiswa kwe-PH lulinganiselwe. Lapho ulungisa inani elifanayo le-PH, inani le-sodium carbonate lizoba likhulu kunaleso se-sodium hydroxide. Umphumela Wokusetshenziswa unakekelwa isikhathi eside, futhi i-PH yamanzi akulula ukuyiyeka.

I-Sodium Hydroxide isizinda esiqinile kanye ne-electrolyte eqinile, i-sodium hydroxide ukulungisa inani le-PH likhulu, qhathanisa ne-sodium hydrolide ngemuva kokuqothula i-ph Ukwanda, nokho, inani le-sodium hydroxide elingeziwe alilikhulu, okungukuthi, amandla amanzi okuqinisa i-acid yeqembu le-hydroxide awenyuki kakhulu, i-PH izokwehla kungekudala.

4.2 Ukulimala okubangelwa ukwengeza ngokweqile kwe-sodium carbonate ne-sodium hydroxide ukwandisa inani le-PH lamanzi okuphakelayo okuphakelayo kwehlukile

Ukungeza kakhulu i-sodium carbonate emanzini ama-boiler ukuguqula inani le-PH kuzokwandisa okuqukethwe usawoti kwamanzi embiza kanye nokuqhutshwa; Kunama-bicarbonate ions amaningi emanzini embizeni, futhi ama-bicarbonate ion abunjwe kalula ibe yikhabhoni dioksijini lapho efudumele. I-CO2 ingena e-Exchanger yokushisa namanzi avumelanayo nomusi. I-sodium carbonate ayikwazi nje ukulungisa ivelu ye-PH ye-Steam kanye ne-Steam condensate Amanzi, kepha futhi inciphisa inani le-PH ye-Steanger kanye ne-condensate, i-corlode the exchanger nepayipi lokushisa. Isizathu esenza ukuthi i-iron oons kumanzi okubuyisa ama-steam adlula umbala ophuzi ophuzi noma obomvu.

Ukungeza kakhulu i-sodium hydroxide emanzi ezimlilo ukulungisa inani le-PH kuzodala ukuthi i-ALkali Yamanzi ebhodweni ibe phezulu kakhulu, futhi amanzi ne-soda kuzovela. Inani le-sodium hydroxide akulula ukulawula, futhi i-naoh ekhululekile ngokweqile izodala i-alkalinity enkulu ehlobene ne-alkality, futhi i-alkali effortlement izobangela ukugqwala kwemishini. Umbhali ubone i-fiber fiber eqiniswe ithangi le-debrine yepulasitiki eligcwele iziqeshana endaweni yomsebenzisi, eyayigcwele futhi yagcwala ngenxa yokusebenzisa i-sodium hydroxide ukulawula inani le-ph.. I-Sodium Hydroxide ayikwazi ukulungisa inani le-PH ye-Steam kanye ne-Steam Condensation libuyisela amanzi, futhi alikwazi ukulawula ukugcwala komusi kanye ne-Steam Condensation Buyisela imishini yamanzi nenethiwekhi yepayipi.

4.3 Ukuphepha kwe-sodium carbonate ne-sodium hydroxide esetshenziswa emanzini okuphakelayo ama-boiler ukukhulisa inani le-PH kuhlukile

I-Sodium Carbonate imnene, ingeyokudla ibanga lokudla, ukukhuthaza okuncane, ukugqwala okuncane, okujwayelekile kungathintwa ngesandla, isidingo sesikhathi eside sokugqoka amagilavu.

I-Sodium Hydroxide iyinto eyingozi, i-Complocinal, futhi isixazululo noma uthuli lwayo lwafakelwa esikhunjeni, ikakhulukazi kulwelwesi lwe-mucous, lungakhiqiza ama-scabs athambile, futhi lingangena izicubu ezijulile. Ukushiswa kushiya isikhafu. Ukungena esweni, akulimazi kuphela i-cornea, kepha futhi kulimaze nezicubu ezijulile zeso. Ngakho-ke, opharetha kufanele asebenzise amafutha angathathi hlangothi ne-hydrophobic esikhunjeni, futhi kufanele agqoke izingubo zomsebenzi, ama-masks, amagilavu ​​okuvikela, amabhuzu enjoloba, amabhuzu enjoloba, amabhuzu enjoloba amade okuthola umsebenzi omuhle wokuvikelwa komuntu siqu.

Kukhona amacala okusebenzisa kanye namacala okuhlola akhombisa: i-sodium hydroxide kanye ne-sodium carbonate asetshenziswa ngokuhlukile, noma ahlanganisiwe, umnotho wawo kanye nomphumela ungcono kunokusebenzisa umlawuli othile we-PH. Lapho inani le-PH lamanzi okuphakelayo ama-boiler atholakala liphansi kakhulu, ezinye i-sodium hydroxide zingangezelelwa ngokufanele lapho zikhulisa ngokushesha inani le-PH. Ngemuva kokuthi i-sodium hydroxide ichitshiyelwa ngokuphelele, i-sodium carbonate ingangezwa ukukhulisa i-carbonate emanzini. Lokhu kungadambisa ukwehla kwenani le-PH ye-Feed Water; Ngoba inani le-sodium carbonate lingafakwa ngaphezulu, amandla okugcina ama-carbonates emanzini athe xaxa ukulondolozwa kwenani le-sodium liphansi, ukuze umlobi ancoma ukusetshenziswa kwe-sodium hydroxide ngokushesha, ukuze bobabili ababili baxubekile, bobabili nomphumela wezomnotho kanye nomphumela omuhle.
