Vim li cas ntxiv cov tshuaj tiv thaiv corrosion thiab surfactants rau cov tshuaj lithium bromide?
Lithium bromide tov yog ntsev uas muaj halogen bromine (Br) thiab alkali hlau lithium (Li). Lithium bromide tov yog corrosive rau hlau cov ntaub ntawv, thiab nws yog ib tug muaj zog corrosive nruab nrab rau hlau cov ntaub ntawv xws li carbon steel thiab tooj liab feem ntau siv nyob rau hauv lithium bromide absorption units. Lub luag haujlwm ntawm oxygen thiab hlau yog qhov tseem ceeb ntawm corrosion. Nyob rau hauv qhov kev txiav txim ntawm oxygen, hlau hlau thiab tooj liab reacts nrog oxygen thiab dej nyob rau hauv ib tug alkaline lithium bromide tov los tsim hydroxides, uas nws thiaj li tsim corrosion khoom xws li ferroferric oxide. Cov electrons poob los ntawm oxidation ntawm hlau thiab tooj liab ua ke nrog hydrogen ions nyob rau hauv cov tshuaj los tsim hydrogen, uas yog ib tug uas tsis yog-condensable gas.
Yog li ntawd, cais cov kab ke ntawm cov pa oxygen yog qhov tseem ceeb tshaj plaws los tiv thaiv corrosion. Ib txwm tswj hwm lub tshuab nqus tsev siab hauv lub cev, them nyiaj nitrogen rau kev saib xyuas lossis tswj lub tshuab nqus tsev thaum kaw, thiab ntxiv cov tshuaj tiv thaiv corrosion rau cov tshuaj kom cais cov pa oxygen thiab inhibit cov nyhuv corrosive ntawm lithium bromide kua. Cov tshuaj tiv thaiv corrosion ntxiv rau cov tshuaj tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau nto los ntawm cov tshuaj tiv thaiv los tiv thaiv nws los ntawm kev tawm tsam los ntawm oxygen lossis tsawg dua, yog li ua rau muaj kev tiv thaiv corrosion. Lithium chromate los yog lithium molybdate feem ntau yog siv los ua corrosion inhibitor. Yog tias lithium chromate siv los ua cov tshuaj tiv thaiv corrosion, chromium hydroxide yog lub ntsiab ntawm cov yeeb yaj kiab tiv thaiv. Ntxiv 0.1 feem pua rau 0.3 feem pua lithium chromate rau cov tshuaj lithium bromide, thiab kho tus nqi pH hauv thaj tsam ntawm 9 txog 10.5. Nws muaj qhov zoo corrosion inhibition nyhuv. Lub solubility ntawm lithium chromate nyob rau hauv lithium bromide kua yog tsawg heev. Nyob rau theem pib ntawm lub tub yees ua haujlwm, ntau lithium chromate yog siv los tsim cov yeeb yaj kiab tiv thaiv. Tom qab khiav mus rau ib lub sijhawm, cov yeeb yaj kiab tiv thaiv maj mam thickens thiab cov concentration ntawm lithium chromate txo qis, uas tuaj yeem ntxiv raws li qhov xwm txheej.
Qhov cuam tshuam ntawm Lithium Bromide Solution Zoo ntawm Chiller
Lithium bromide tov yog rau lithium bromide chav tsev, ib yam li cov ntshav yog rau tib neeg lub cev, thiab cov ntshav zoo yog ncaj qha ntsig txog kev noj qab haus huv ntawm lub cev. Yog li niaj hnub no, cia peb kawm txog qhov cuam tshuam ntawm qhov zoo ntawm lithium bromide tov ntawm "kev noj qab haus huv" ntawm chav tsev.
Hais txog lithium bromide kua
Ua ntej, cia peb saib cov tshuaj lithium bromide:
Cov tshuaj lithium bromide tuaj yeem tsim los ntawm kev yaj lithium bromide (khoom) hauv dej. Nws cov khoom tseem ceeb yog lithium (Li) thiab bromine (Br), uas yog cov hlau alkali thiab halogen pawg ntsiab lus. Lawv cov khoom zoo ib yam li cov ntsev ntsev (NaCl) thiab feem ntau tsis deteriorate, decompose, los yog evaporate nyob rau hauv cov huab cua.
Lithium bromide kua yog cov kua uas tsis muaj xim thiab pob tshab, nrog cov ntsev thiab iab saj ntawm qhov nkag thiab khaus me ntsis thaum txaws ntawm daim tawv nqaij. Tom qab ntxiv lithium chromate, cov tshuaj hloov daj me ntsis, thiab tom qab ntxiv lithium molybdate, nws zoo li tsis muaj xim thiab pob tshab.
Cov yam ntxwv cuam tshuam rau corrosiveness ntawm lithium bromide tov rau hlau
Lithium bromide tov yog corrosive rau hlau, thiab nws muaj feem cuam tshuam cov yam ntxwv muaj xws li:
1. Tshuaj kub. Thaum cov tshuaj nce mus txog 165 degrees Celsius, nws corrosiveness yuav sharply nce;
2. Tshuaj pH lossis lithium hydroxide concentration. Tus nqi pH ntawm cov tshuaj feem ntau yog nyob nruab nrab ntawm 9.0 thiab 10.5, thiab nws yog acidic thaum nws tsawg dua 7, ua rau cov hlau corrosion hnyav heev. Thaum nws loj dua 11.5, nws tseem yuav ua rau corrosion ntau dua;
3. Qhov loj feem ntawm lithium bromide nyob rau hauv cov tshuaj. Cov hlau hlau thiab tooj liab hauv cov tshuaj alkaline lithium bromide yuav ua ke nrog oxygen los tsim cov hlau thiab tooj liab oxides, xws li hlau tetroxide lossis tooj liab hydroxide. Nyob rau tib lub sijhawm, cov hluav taws xob poob los ntawm oxidation ntawm hlau thiab tooj liab ua ke nrog hydrogen ions (H ntxiv) hauv kev daws teeb meem los tsim cov roj uas tsis yog condensable H ₂.
Lub hauv paus mob rau cov kev tshwm sim saum toj no yog muaj cov pa oxygen. Yog li ntawd, cais cov pa oxygen yog qhov kev ntsuas tseem ceeb tshaj plaws kom tsis txhob muaj kev cuam tshuam sab hauv thiab daws cov pa phem hauv chav tsev.
Teeb meem nrog chav tsev tom qab kev daws teeb meem
Qhov zoo ntawm lithium bromide tov ncaj qha cuam tshuam rau kev ua haujlwm ntawm lithium bromide absorption units. Cov tshuaj yog zoo li cov ntshav ntawm ib chav nqus nqus. Thaum 'ntshav' muaj paug, chav tsev yuav muaj ntau yam 'cov tsos mob', xws li:
① Txo lub peev xwm nqus;
② Ntau yam impurities generated los ntawm corrosion thaiv lub tshav kub exchanger raj hauv lub tshav kub exchanger;
③ Corrosion thiab kev puas tsuaj rau sab hauv xws li lub impeller thiab lub tes tsho ntawm lub twj tso kua mis shielded;
④ Lub tsev tau ntsib kev sib tsoo ntawm cov raj xa hluav taws xob thiab thaiv cov phaj da dej, zoo ib yam li cov hlab ntsha txhaws thiab los ntshav hauv tib neeg lub cev, ua rau cov ntshav tsis txaus.
Thaum lub voj voog ntim ntawm cov tshuaj tsis txaus, nws yuav txo qhov kev ua haujlwm ntawm cov cua sov sab hauv thiab kev nqus dej ntawm chav tsev. Yog li ntawd, cov tshuaj lithium bromide, zoo li tib neeg cov ntshav, yuav tsum tau kho sai yog tias muaj teeb meem tshwm sim.
Cov Lus Nug Nquag Tshaj Qhia
Peb tuaj yeem pom pom los ntawm cov duab hauv qab no tias qhov kev puas tsuaj sab hauv, corrosion, thiab thaiv ntawm chav tsev yog tshwm sim los ntawm qhov teeb meem ntawm kev daws teeb meem.
