Lub luag haujlwm tseem ceeb ntawm boiler softening resin yog tshem tawm calcium thiab magnesium ions los ntawm dej los ntawm kev sib pauv ion. Txawm li cas los xij, tom qab cov resin hloov mus rau qee qhov nyiaj, nws yuav tsis tuaj yeem hloov sodium thiab magnesium ions hauv dej. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog yuav tau rov tsim dua lub boiler softening resin. Txawm li cas los xij, ntau tus neeg siv tsis paub txog kev ua haujlwm ntawm cov khoom siv rov ua dua tshiab ntawm boiler softened resin, uas ua rau muaj teeb meem thaum rov tsim dua tshiab. qhov no
Lub hauv paus ntsiab lus ntawm boiler softening resin regeneration
Thaum lub boiler softening resin hloov ib co hardness ions xws li calcium thiab magnesium nyob rau hauv dej, nws yuav tsis muaj peev xwm mus soften cov dej. Nyob rau lub sijhawm no, lub tshuab nqus dej yog xav tau rau resin regeneration, uas yog txo cov txheej txheem rov ua dua tom qab resin calcium pollution.
(1) Thaum regenerating muaj zog cation txauv resin nrog Na tov, nws yog advisable coj ib tug step-by-step regeneration txoj kev. Pib rov tsim dua tshiab nrog cov concentration tsawg ntawm Na daws, raws li Ca2+ concentration desorbed los ntawm cov resin siab, tab sis Na concentration tsawg. Txawm hais tias ib qho me me ntawm Ca2+Na precipitate raug tsim, nws yuav raug ntxuav los ntawm cov tshuaj. Tom qab ntawd maj mam nce cov Na concentration, ntawm qhov taw tes Ca2 desorbed los ntawm cov cob +
Tsawg concentration yuav tsis tsim Na nag lossis daus.
(2) Vim lub fact tias tsis muaj zog cation txauv resin yog regenerated siv pov tseg kua los ntawm muaj zog cation txauv resin. Yog li ntawd, thaum nkag mus rau hauv cov kua qaub, qhov tsis muaj zog cation exchanger yuav tsum tau ntim nrog cov dej diluted (JF9201 lim dej), thiab cov dej inlet yuav tsum tsis txhob tshaj cov kua qaub inlet ntawm lub exchanger. Tsis tas li ntawd, xyuam xim rau kev soj ntsuam cov xim ntawm cov kua regenerated pov tseg tawm los ntawm cov tsis muaj zog cation exchanger. Yog hais tias nws tshwm raws li ib tug dawb turbid tshuaj, txawm yog hais tias tus acid concentration yog kho.
(3) Tom qab cov kua qaub ntxiv, qhov tsis muaj zog cation exchanger yuav tsum tau hloov tam sim ntawd thiab ntxuav nrog lim dej los ntawm JF9201, thaum lub zog cation exchanger yuav tsum tau hloov thiab ntxuav nrog purified dej tam sim ntawd.
(4) Nyob rau lub caij ntuj no, vim qhov kub ntawm cov txheej txheem rov ua dua tshiab, cov kua qaub calcium ntau dua yuav tshwm sim. Yog li ntawd, ua ntej rov tsim dua tshiab, qhov tsis muaj zog cation exchanger yuav tsum tau txhuam thiab rov qab ntxuav, thiab cov kav dej rau cov kua dej rov qab los ntawm cov tsis muaj zog cation exchanger thiab cov cation exchanger muaj zog yuav tsum tau rov qab ntxuav kom tsis txhob muaj teeb meem. Cov txheej txheem no yuav siv sij hawm 2-3 teev nyob rau hauv cov khoom siv dej mos thiab feem ntau hu ua backwash regeneration ntawm cov khoom muag dej. Ib tug npaum li cas ntawm resin regeneration agent (Na) yuav tsum tau nyob ntawm seb hom dej softening khoom.
