Kugereranya ibyiza n'ibibi byo gukoresha sodium carbonate cyangwa sodium hydroxide kugira ngo uhindure agaciro ka pH ku mazi yo mu ifu y'amazi yo mu ifu

1, amazi yo mu gikoni kugira ngo ahindure agaciro ka pH k'impamvu

Muri iki gihe, amaboiler menshi mu Bushinwa akoresha amazi ya reverse osmosis adacukurwaho amabuye cyangwa sodium ion resin exchange soft water, reverse osmosis adacukurwaho amabuye cyangwa sodium ion resin exchange soft water pH igizwe ahanini na aside nkeya kandi ivanze na aside, reverse osmosis adacukurwaho amabuye igizwe na pH igizwe na 5-6, sodium ion resin exchange soft water pH igizwe na 5.5-7.5, kugira ngo hakemuke ingese y’amazi aside atangwa n’amaboiler n’imiyoboro, Dukurikije ibiteganywa n’amategeko y’igihugu ya BG/T1576-2008, pH y’amazi ya boiler y’inganda iri hagati ya 7-9 naho pH y’amazi adacukurwaho amabuye iri hagati ya 8-9.5, bityo amazi ya boiler agomba guhindura pH.

2, ihame ry'ibanze ryo kongeramo sodium karubone mu mazi yo mu icupa ry'amazi kugira ngo hakosorwe agaciro ka pH

Karubone ya sodiyumu izwi cyane nka soda, ivu rya soda, ivu rya soda, alkali yoza, ishyirwa mu cyiciro cy'umunyu, atari alkali, formula ya shimi Na2CO3, mu bihe bisanzwe ku ifu yera cyangwa umunyu mwiza. Ihame ry'ibanze ryo kongeramo karubone ya sodiyumu mu mazi yo koza kugira ngo uhindure agaciro ka pH ni ugukoresha karubone ya sodiyumu kugira ngo isohoke mu mazi kandi ibe alkali, ishobora kugabanya dioxyde de carbone mu mazi yo koza aside no gukemura ingese y'amazi yoroshye ya aside cyangwa amazi y'umunyu kuri karubone n'umuyoboro. Karubone ya sodiyumu ni electrolyte idakomeye, ishongeshejwe mu mazi kugira ngo ikore igisubizo cya karubone ya sodiyumu na bicarbonate ya sodiyumu, hari uburinganire bwa electrolytic mu gisubizo, hamwe no gukoresha hydroxide ya electrolytic, uburinganire buzakomeza kujya iburyo, bityo pH iri mu gikorwa ntihinduka cyane.

Uburyo bwa hydrolysis y’ibanze ya sodium carbonate:

Na2CO3 Sodium karubone +H2O amazi = NaHCO3 sodium bikarubone +NaOH sodium hidroxide

Uburyo bwo gukamura hydrolysis ya sodium carbonate secondary:

NaHCO3 sodium bicarbonate + H2O amazi = H2CO3 aside karubone + NaOH sodium hidroxide

Ingano ya iyoni ya hidrolisize ya sodium karubone y’ibanze:

(CO3) aside karubone 2 + H2O amazi = HCO3- bikarubone + OH- hidroksidi

Ingano ya iyoni ya hydrolyzed hydrolyzed sodium carbonate secondary:

HCO3- bicarbonate + H2O amazi = H2CO3 aside karubone + OH- hidroksidi

3, ihame ry'ibanze ryo kongeramo sodium hydroxide mu mazi ya boiler kugira ngo hakosorwe agaciro ka pH

Hydroxide ya sodiyumu yitwa kandi caustic soda, caustic soda, caustic soda, caustic soda, ubusanzwe umweru, formula ya shimi NaOH, sodiyumu hydroxide ifite alkaline ikomeye, irangiza cyane.

Ingano ya Ionisation kuri sodium hydroxide: NaOH=Na++OH-

Kongeramo sodium hydroxide mu mazi y’icyuma bishobora gutuma icyuma gikingira kiri hejuru y’icyuma gikomeza guhagarara, bikongera pH y’amazi akoreshwa muri icyuma n’amazi yo mu itanura, bityo bigakemura ingese y’amazi yoroshye cyangwa amazi adasukuye ari kuri icyuma n’umuyoboro, kandi bikarinda ibikoresho by’icyuma ingese.

4. Ibyiza n'ibibi byo gukoresha sodium karubone cyangwa sodium hydroxide kugira ngo uhindure agaciro ka pH ku mazi yo mu gikoni cy'amazi biragereranywa.

4.1 Umuvuduko wo kuzamura agaciro ka pH ukoresheje sodium karubone na sodium hydroxide ku mazi akoreshwa muri boiler n'igihe cyo gukomeza gukoresha biratandukanye

Umuvuduko wo kongeramo karubone ya sodiyumu mu mazi akoreshwa mu icupa ry’amazi kugira ngo wongere agaciro ka pH ni muto ugereranije n’uwa karubone ya sodiyumu. Kubera ko karubone ya sodiyumu ikora umuti w’amazi, ifite ihindagurika rito kandi ihamye kandi yoroshye kuyihindura. Ariko, urwego rw’ihinduka rya pH ni ruto. Iyo uhinduye agaciro ka pH kamwe, ingano ya karubone ya sodiyumu izaba nini kuruta iya karubone ya sodiyumu. Ingaruka zo kuyikoresha zigumaho igihe kirekire, kandi pH y’amazi ntiyoroshye kuyigabanya.

Sodium hydroxide ni ishingiro rikomeye kandi ni electrolyte ikomeye, sodium hydroxide yo guhindura agaciro ka pH y’ihindagurika ni nini, sodium hydroxide nyuma yo kongeramo amazi pH biroroshye kongera, guhindura agaciro ka pH vuba kandi mu buryo butaziguye, ariko kandi byoroshye kuyihindura ntibishobora gushyiramo byinshi, ugereranije na sodium carbonate kongeramo bike cyane bishobora kugera ku gipimo cya pH, ni ukuvuga ko nubwo agaciro ka sodium hydroxide pH kiyongereye, Ariko, ingano ya sodium hydroxide yongewemo si nini, ni ukuvuga ko ubushobozi bw'amazi bwo kugabanya aside y'itsinda rya hydroxide butiyongera cyane, pH izagabanuka vuba.

4.2 Ingaruka ziterwa no kongeramo cyane sodium karubone na sodium hydroxide kugira ngo boiler feeding amazi irusheho kuba nziza, zitandukanye.

Kongeramo sodium karubone nyinshi mu mazi yo mu icupa kugira ngo hakosorwe pH bizongera umunyu mu mazi yo mu nkono ndetse n'uburyo amazi akoreshwa mu gucukura; Hari ioni nyinshi za bicarbonate mu mazi yo mu nkono, kandi ioni za bicarbonate zoroshye kubora muri dioxyde de carbone iyo zishyushye. CO2 yinjira mu cyuma gihindura ubushyuhe maze igahindura amazi hamwe n'umwuka. Sodium karubone ntabwo ishobora gusa guhindura pH y'amazi asubiza umwuka n'umwuka, ahubwo inagabanya pH y'umwuka n'umwuka, bigatera kwangirika kw'umuyoboro uhindura ubushyuhe n'umwuka. Impamvu ioni z'icyuma mu mazi asubiza umwuka zirenze ibara risanzwe ry'umuhondo cyangwa umutuku.

Kongeramo sodium hydroxide nyinshi mu mazi yo mu itanura kugira ngo hakosorwe pH bizatuma amazi yo mu nkono ya alkali aba menshi cyane, kandi amazi na soda bizagaragara. Ingano ya sodium hydroxide ntabwo byoroshye kuyigenzura, kandi NaOH idafite alkali nyinshi izatuma habaho alkali nyinshi, kandi alkali nayo izatera ingese ku bikoresho. Umwanditsi yabonye ikigega cya plastiki cyuzuyemo uduce tw’ibirahure tw’umugozi w’amazi kiri aho umukoresha akorera, cyarangiritse kandi kibomoka kubera ikoreshwa rya sodium hydroxide mu kugenzura pH y’ibinyabiziga. Sodium hydroxide ntishobora guhindura pH y’amazi agarura umwuka n’umwuka, kandi ntishobora kugenzura ingese y’ibikoresho by’imiyoboro n’imiyoboro.

4.3 Umutekano wa sodium karubone na sodium hydroxide bikoreshwa mu mazi yo mu ifuru kugira ngo byongera agaciro ka pH uratandukanye

Sodium karubone ni ntoya cyane, ikoreshwa mu bikoresho byo mu rwego rw'ibiribwa, ikoreshwa mu buryo buke, yangiritse gato, ikoreshwa mu buryo busanzwe n'intoki, kandi ikenera kwambara uturindantoki igihe kirekire.

Hydroxide ya sodiyumu ni ikintu kibi, cyangiza, kandi umuti wayo cyangwa ivumbi ryasutswe ku ruhu, cyane cyane ku gice cy'umuhogo, bishobora gutera udukoko tworoshye, kandi bishobora kwinjira mu ngingo zimbitse. Ubushye busiga inkovu. Kwisuka mu jisho, ntabwo byangiza gusa cornea, ahubwo byangiza n'ingingo zimbitse z'ijisho. Kubwibyo, umuntu ubikora agomba gushyira amavuta atagira uburyaryate n'amazi ku ruhu, kandi agomba kwambara imyenda y'akazi, udupfukamunwa, indorerwamo zo kurinda, uturindantoki twa rubber, ama-apron ya rubber, inkweto ndende za rubber n'ibindi bikoresho byo kurinda abakozi kugira ngo akore akazi keza ko kurinda umuntu ku giti cye.

Hari ingero z’ikoreshwa n’igeragezwa zigaragaza ko: Sodium hydroxide na sodium carbonate bikoreshwa mu buryo butandukanye, cyangwa bivanze, ubukungu n’ingaruka byabyo ni byiza kuruta gukoresha uburyo runaka bwo kugenzura pH gusa. Iyo agaciro ka pH k’amazi yo mu gikoni cy’amazi afunguye boiler kagaragaye ko ari gake cyane, sodium hydroxide imwe ishobora kongerwamo neza kugira ngo yongere vuba agaciro ka pH. Nyuma yuko sodium hydroxide ishongeshejwe burundu, sodium carbonate imwe ishobora kongerwamo kugira ngo yongere karubone mu mazi. Ibi bishobora koroshya igabanuka ry’agaciro ka pH k’amazi yo mu gikoni; Kubera ko ingano ya sodium carbonate ishobora gushyirwamo nyinshi, ubushobozi bwo kubungabunga karubone mu mazi ni bwinshi, bityo ubusanzwe sodium carbonate ishobora gukoreshwa mu kubungabunga agaciro ka pH k’amazi n’amazi yo mu nkono, gusa iyo agaciro ka pH k’amazi ari gake cyane, umwanditsi atanga inama yo gukoresha sodium hydroxide kugira ngo yongere vuba agaciro ka pH, kugira ngo byombi bivange, haba mu buryo bunoze kandi bwiza.
