Kurapa Mvura: Quicklime kana Hydrated Lime - Ndeipi iri Nani?

Munyaya yekurapa nemvura , sarudzo pakati pequicklime (calcium oxide, CaO) uye hydrated lime (calcium hydroxide, Ca(OH)₂) chisarudzo chakakosha chinogona kukanganisa zvakanyanya kushanda zvakanaka, mutengo, uye nharaunda yekurapa. Zvinhu zvese izvi zvine basa rakakosha mukushandiswa kwakasiyana-siyana kwekurapa mvura, asi hunhu hwazvo hwakasiyana uye maitiro azvo zvinoita kuti zvive zvakakodzera mumamiriro ezvinhu chaiwo. Ngationgororei kuenzanisa kwakadzama kuti tione kuti ndeipi ingave sarudzo iri nani kune zvaunoda pakurapa mvura.

Chemical Reactions uye pH Kugadziriswa

Kana quicklime yawedzerwa kumvura, inosangana nekusagadzikana, inokurumidza kuburitsa kupisa uye ichishandura kuita hydrated lime: CaO + H₂O → Ca (OH) ₂. Kuita uku kune simba guru uye kunogona kukwidza tembiricha yemvura zvakanyanya. Kune rumwe rutivi, hydrated lime inenge yatova mu hydroxide fomu uye inonyunguduka mumvura pasina mhirizhonga yakadaro yekupisa.

Ose ari maviri quicklime uye hydrated lime anoshanda mukugadzirisa pH yemvura. Iwo akasimba alkalis anogona kuderedza mvura ine acidic, ichiita kuti ive yakakodzera kune imwezve kurapwa kana yakachengeteka pakubuda. Nekudaro, nekuda kwekuenderera mberi kwekushandurwa kwequicklime kune hydrated lime mumvura, inogona kupa yakawedzera tsigiro sosi yealkalinity yekugadziriswa kwepH. Izvi zvinogona kubatsira mukurapa yakanyanya acidic tsvina yeindasitiri, uko kunowedzera uye kunoramba kuchiwedzera kwepH kunodiwa.

Disinfection uye Pathogen Kubviswa

Quicklime's exothermic reaction, yakasanganiswa neiyo yakakwirira pH yainogadzira, inoita kuti ive yakanakisa disinfectant. Kupisa kunogadzirwa kunogona kukanganisa mapuroteni uye maseru membranes ezvirwere, nepo alkalinity yakakwira ichiuraya mabhakitiriya mazhinji, mavhairasi, uye tupukanana. Izvi zvinoita kuti quicklime inonyanya kubatsira mumamiriro ekukurumidzira ekugadzirisa mvura kana mukurapa zvitubu zvemvura zvine njodzi huru yekusvibiswa kwepathogen, senge mune dzimwe nzvimbo dzichiri kusimukira kana mushure menjodzi dzinongoitika dzoga.

Hydrated lime inewo zvimwe zvekuuraya hutachiona nekuda kwealkalinity yayo. Inogona kubatsira kudzora kukura kwema microorganisms mumvura, kunyanya mumasisitimu ekugovera mvura uko kuchengetedza zvishoma alkaline pH kunogona kutadzisa kukura kwemamwe mabhakitiriya. Zvisinei, simba rayo rekuuraya utachiona kazhinji harina kusimba sezvakaita riya rekukurumidza.

Kunaya uye Kubviswa Kwekusvibiswa

Ese ari maviri quicklime uye hydrated lime anogona kuita nekusachena kwakasiyana-siyana mumvura kuti agadzire mvura, iyo inogona kubva yabviswa kuburikidza ne sedimentation kana kusefa maitiro. Semuenzaniso, vanogona kuita ne phosphates kuumba calcium phosphate precipitates, zvichibatsira kubvisa phosphorus kubva mumvura. Izvi zvakakosha mukudzivirira eutrophication mumvura yemvura, sezvo phosphorus yakawandisa inogona kutungamirira kumaruva ealgal uye kupera kweokisijeni.

Kana simbi dzinorema dzichibviswa, lime yakanyorova ndiyo inonyanya kufarirwa. Inogona kuita maion esimbi dzinorema dzakadai se lead, MERCURY , uye cadmium kuti igadzire mahydroxide esimbi asinganyunguduki. Ma precipitate aya anogona kuparadzaniswa nyore nyore nemvura, zvichideredza huwandu hwesimbi inorema. Kuita kwakaderera kwe lime yakanyorova kana tichienzanisa ne quicklime kunoita kuti ive yakakodzera kushandiswa uku, sezvo ichibvumira kudzora kuri nani kwemvura.

Mutengo uye Kubata Kufunga

Mutengo chinhu chakakosha pakurapa kwemvura. Quicklime kazhinji inodhura - inoshanda kupfuura hydrated lime pane imwe - unit - mass basis. Izvi zvinodaro nekuti quicklime ndiyo yakasvibirira iyo hydrated lime inogadzirwa, uye iyo yekuwedzera yekugadzirisa inodiwa kushandura quicklime kune hydrated lime inowedzera kumutengo wekupedzisira. Muzviyero zvakakura zvekuchenesa mvura, mari inochengetwa kubva pakushandisa quicklime inogona kuve yakakura.

Zvisinei, kubata quicklime kunoda kutarisirwa kwakawanda. Kuita kwayo kwakanyanya nemvura kunogona kuunza njodzi dzekuchengetedza kana isina kunyatsogadziriswa. Midziyo yakasarudzika uye maitiro ekuchengetedza anodiwa kuchengetedza, kutakura, uye kusanganisa quicklime nemvura. Kusiyana neizvi, hydrated lime inogadzikana uye iri nyore kubata. Inogona kuchengetwa mumidziyo yenguva dzose uye yakasanganiswa nemvura uchishandisa midziyo yakajairwa, zvichiita kuti ive sarudzo iri nyore kune dzimwe nzvimbo diki dzekuchenesa mvura kana mumamiriro ezvinhu apo kuchengetedzeka uye nyore kubata kunoiswa pamberi.

mhedziso

Mukupedzisa, sarudzo pakati pequicklime uye hydrated lime mukurapa kwemvura kunoenderana nemhando dzakasiyana siyana. Kana uri kubata nemvura ine acid yakawanda, unoda mushonga wekuuraya utachiona wakasimba, kana uri kutsvaga mutengo - unoshanda kurapwa pamwero mukuru, quicklime inogona kunge iri sarudzo iri nani. Kune rimwe divi, kana iwe uchida kunyatso kudzora maitiro ekurapwa, uchitarisa pane inorema kubviswa kwesimbi, kana kuda chinhu chinobatwa zviri nyore, hydrated lime inogona kunge iri sarudzo yakakodzera.

Pakupedzisira, kuongororwa kwakadzama kwemhando yemvura, zvibodzwa zvekurapa, zvinodiwa zvekuchengetedza, uye zvipingamupinyi zvemutengo zvinodikanwa kuita sarudzo ine ruzivo. Nekunyatsofunga nezvezvinhu izvi, nyanzvi dzekurapa mvura dzinogona kusarudza iyo yakanyatsokodzera lime - yakavakirwa nzira yekurapa kuti iwane yakakwana mhando yemvura uye kunyatso kurapa.
