Kuenzanisa kwezvakanakira uye zvakashata zvekushandisa sodium carbonate kana sodium hydroxide yekugadzirisa ph kukosha kwe boiler inopa mvura yekupa mvura

1, boiler inopa mvura yekugadzirisa iyo PH Kukosha kwechikonzero

Mazuva ano, madhiri mazhinji muChina Shandisa Reverse Osmosis Water Mvura yePR Chesin School Acadic mvura inopa mabheya uye mapepa, maererano nezvinopihwa zveNational Standard BG / T1576 Mvura iri pakati pe8-9.5, saka mvura yemubhadharo inoda kugadzirisa iyo inoda kugadzirisa iyo pH.

2, iyo yekutanga nheyo yekuwedzera sodium carbonate kune boiler inopa mvura yekupa mvura yekugadzirisa iyo pH kukosha

Sodium carbonate inowanzozivikanwa seSoda, Soda Ash, Soda Ath, yakasarudzika seyalkali, kwete Alkali, yemakemikari formula na2co3, pasi pemamiriro ezvinhu akachena kana munyu waye. Nheyo yekutanga yekuwedzera sodium carbonate kune iyo builer yekupa iyo kabhoni yekukasira yekunyungudika mvura uye gadzirisa iyo acidic mvura yakanyoroveswa mvura kana mvura yemunyu pane bhuti uye pombi. Sodium carbonate isina kusimba emagetsi, akanyungudutswa mumvura kuti aumbe-sodium carbonate, pane kusarudzika kweiyo Electrolytic Hydroxide, iyo chiyero chicharamba ichienda kurudyi, saka phpo parizvino mukuita hazvichinje zvakawanda.

Sodium carbonate Primary Hydrolysis Process:

Na2co3 Sodium Carbonate + H2O Mvura = Nahco3 Sodium Bicarbonate + Naoh Sodium Hydroxide

Sodium kabhoni yechipiri hydrolyis maitiro:

Nahco3 sodium bicarbonate + h2o mvura = H2CO3 Carbonic acid + naoh Sodium Hydroxide

Sodium carbonate primary hydrolyzed ion equation:

.

Sodium carbonate sekondari hydrolyzed ion equation:

HCO3- Bicharbonate + H2O Mvura = H2CO3 Carbonic Acid + O OH- Hydroxide

3, iyo yekutanga nheyo yekuwedzera sodium hydroxide kumvura yemubhoti yekugadzirisa iyo pH kukosha

Sodium Hydroxide inonziwo Caustic soda, Caustic Soda, Caustic Soda

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

Kuwedzera sodium hydroxide kumvura yemubhoti kunogona kudzikisira firimu rekudzivirira pamusoro pesimbi yemvura, kuti mvura yaburitswa, uye pombi, uye chengetedza midziyo yesimbi kubva kuCorrosion.

4.1 Iko kumhanya kwekukwidza ph kukosha neSodium kabhoni uye sodium hydroxide ye boiler yekupa mvura yekupa mvura uye nguva yekuchengetedza iyo yekushandisa yakasiyana

Kumhanya kwekuwedzera sodium carbonate kumabhayeti mvura yekuwedzera kuti uwedzere kukosha inowedzera zvishoma zvishoma pane iyo ye sodium hydroxide. Nekuti sodium carbonate inogadzira Buffer Solution, ine madiki madiki uye yakagadzikana uye iri nyore kugadzirisa. Nekudaro, huwandu hwePP kugadzirisa kunogumira. Paunenge uchigadzirisa iyo yakafanana pH kukosha, huwandu hwesodium kabhoni zvichave zvakakura kupfuura izvo zveSodium hydroxide. Iko kushandiswa kwekushandisa kunochengetwa kwenguva yakareba, uye iyo pH yemvura hazvisi nyore kudonha.

Sodium Hydroxide Chigadziko Chakasimba uye Sodium Hydroxide yekugadzirisa PF iri nyore, kana zviri nyore kuwedzeredza kakawanda, Hydroxide ph kukosha kwakawedzera, zvisinei, huwandu hwesodium hydroxide yakawedzerwa haisi yakakura, ndiko kuti, iko kugona kwemvura kuti uregere kweboka reHydroxide hariwedzera zvakawanda, iyo PH ichakurumidza kudonha.

4.2 Iko kukuvadza kunokonzerwa nekuwedzera kwakanyanya kweSodium carbonate uye Sodium Hydroxide kuti uwedzere kupfuhana PL kukosha kweBoiler Fuedy Mvura yakasiyana

Kuwedzera yakawandisa sodium carbonate kumvura yemubhoti kuti igadzirise iyo ph kukosha ichawedzera munyu wemvura yemvura uye unoshanda; Kune zvimwe bicarbonate ions mumvura muhari, uye bicarbonate ions iri nyore nyore kuita carbon dioxide kana ichipiswa. CO2 inopinda inopisa yekushongedza uye mvura yekudzinga nemvura ine steam. Sodium carbonate kwete chete isingakwanise kugadzirisa iyo Steam uye Steam Curnensate Dzidza mvura, asi zvakare inoderedza iyo phengo yeiyo steam uye yekudzora, inogadzirisa iyo yekupisa yekuwedzera uye yekushongedza pombi. Chikonzero nei izwi renzvimbo mu steam curnensate kudzoka mvura inodarika iyo yakajairwa ruvara rweyero kana red ruvara.

Kuwedzera sodium yakawandisa hydroxide kune mvura yemvura yekugadzirisa iyo phengo yacho ichaita kuti pot yemvura alkali ive yakanyanya kusvika, uye mvura nesoda ichaonekwa. Huwandu hweSodium Hydroxide hazvisi nyore kudzora, uye zvakawandisa zvemahara. Iye munyori akaona girazi rakasimbisa purasitiki marara lebled patsanze patsotsi patsotsi panzvimbo yemushandisi, iyo yakagadziriswa uye yakasarudzika nekuda kwekushandiswa kwesodium hydroxide kuti itongere iyo ph kukosha kwemarara. Sodium Hydroxide haigone kugadzirisa iyo PH Kero uye Steam Conversation Dzorera mvura, uye haigone kudzora iyo Corrosion yeSteam uye Steam Curnensation Kudzorera System Equipment uye Pipe Network.

4.3 Iko kuchengetedzwa kweSodium kabhoni uye sodium hydroxide inoshandiswa mune boiler yekupa mvura yekupa mvura kusimudza ph kukosha kwakasiyana

Sodium kabhoni ndeyekunyorova, ndezvekudya zvegiredhi dzegiredhi, kukurudzira kudiki, zvakajairika, zvakajairika zvinogona kubatwa neruoko, kwenguva refu kudikanwa kwekupfeka magurovhosi.

Sodium Hydroxide imidziyo ine njodzi, inokanganisa, uye yekugadzirisa kana guruva rakanyanyisa paganda, kunyanya paiyo mucous membrane, inogona kuburitsa zvakapfava, uye inogona kupinda mukati medumbu. Anopisa anosiya vanga. Kupaza muziso, kwete kungokuvadza chete iyo cornea, asi inokuvadzawo mitezo yakadzika yeziso. Naizvozvo, anoshanda anofanirwa kunyorera zvisina kurapwa uye hydrophobic oiri paganda, uye anodzivirira magirazi, magurovhosi emafuta, mimwe mimwe mimwe mimwe madhiri ekudzivirira kuita basa rekudzivirira.

Pane zviitiko uye zviitiko zvebvunzo zvinoratidza: Sodium hydroxide uye sodium kabhoni inoshandiswa neimwe neimwe, kana kusanganisa, hupfumi hwayo uye hupfumi huri nani pane kushandisa imwezve yekuita soulator chete. Kana iyo PH Kukosha kweiyo boiler yekupa mvura inowanikwa kuve yakaderera, imwe sodium hydroxide inogona kuwedzerwa nenzira kwayo yekukurumidza kuwedzera iyo ph kukosha. Mushure mekunge sodium hydroxide yakanyungudutswa zvachose, imwe sodium carbonate inogona kuwedzerwa kusimudza carbonate mumvura. Izvi zvinogona kusunungura kuderera kweiyo ph kukosha kwemvura yekupa; Nekuti huwandu hwesodium carbonate inogona kuiswa mune zvakawanda, kugona kwekuchengetedza carbonate kuchawedzera kuwanda kweiyo sodium hydroxide kuwedzera iyo inowedzera kuwedzera iyo ph kukosha, kuitira kuti vaviri vacho vakasanganiswa, zvese zvine hupfumi uye zvakanaka.
