Wanem samting em i COC insait long ol 'cooling towers'?

Long lukluk bilong mining na kalkulesen lojik, as bilong COC em i wok bilong skelim hamas sol i stap insait long wara sistem. Taim wanpela 'cooling tower' i wok, wara i save go daun long rot bilong 'evaporative heat dissipation'. Tasol, 'evaporation' i save rausim klinpela wara tasol, tasol ol sol olsem 'calcium ions', 'magnesium ions', na 'chloride ions' we i kapsait insait long wara i save stap yet insait long wara we i raun. Long lukautim gut wara balens bilong sistem, ol i mas givim fres wara oltaim. Ol sol we wara bilong 'makeup' i bringim i kam insait bai bung oltaim, na dispela i mekim na sol insait long wara i ron i go antap tru winim wara bilong 'makeup'. Long tingting, kalkulesen fomula bilong COC em:COC=Konsentresen bilong ol strongpela samting insait long wara i raun / Konsentresen bilong ol strongpela samting i kapsait insait long wara bilong wokim. Long wok na mentenens tru, long mekim wok bilong painimaut i kamap isi, ol i save yusim ol indiketa we ol i ken skelim isi olsem ol 'chloride ions' na 'electrical conductivity' na ol i no save yusim ol 'dissolved solids' bilong skelim, na ol risal tu i gat gutpela pe bilong en.

 

 

 

Level bilong COC indiketa i gat tupela samting long wok bilong 'cooling tower' na em i ki bilong skelim gutpela wok bilong sevim wara na sefti bilong ol ikwipmen. Taim COC veliu i liklik tumas, dispela i min olsem 'discharge frequency' bilong wara i raun i go antap tumas, na dispela i mekim na ol i yusim bikpela wara bilong 'makeup'. Dispela i no save kamapim bikpela westim tasol long ol wara risos tasol tu i save mekim kos bilong yusim ol marasin bilong klinim wara i go antap. Olsem, taim COC veliu em 2, konsumsen bilong wara bilong 'makeup' em 2.5 taim moa long taim COC veliu em 5. Long narapela sait, taim COC veliu i antap tumas, konsentresen bilong ol sol insait long wara i raun bai winim mak bilong 'saturation threshold', we i ken kamapim 'scaling' insait long ol 'heat exchanger', 'coil', na 'pipeline'. Long wankain taim, bikpela konsentresen bilong ol 'chloride ions' bai mekim ol metal ikwipmen i bagarap hariap, na dispela bai mekim 'heat exchange efficiency' bilong 'cooling tower' i go daun, ol ikwipmen i save bagarap planti taim, na bikpela inkris long operesen na mentenens kos.

 

 

 

Long ol wok, ol kain kain 'cooling tower' i gat ol 'COC control ranges' bilong ol, we ol i mas stretim stret bihainim kain ikwipmen, kwaliti bilong wara, na 'cooling medium'. Long ol samting we planti manmeri i save yusim'counter-flow open-circuit cooling towers, bikos long stretpela kontek namel long wara na win i raun, kwaliti bilong wara i save senis planti, na gutpela mak bilong COC kontrol em3-5 saikel. Bilong'cross-flow closed-circuit cooling towers, 'closed-circuit circulation design bilong ol i daunim wara kwaliti polusen, olsem na COC veliu inap long go antap long5-8 saikel. Long ol samting we i gat bikpela wara kwaliti rikwaemen, olsem ol sentral ea-kondisen sistem, COC veliu i save stap insait long3-4 saikelbilong abrusim 'scaling' we i ken bagarapim wok bilong 'refrigeration'. Na tu, strong bilong wara bilong 'makeup' bai i mekim wok long seting bilong COC veliu. Taim hat bilong wara bilong 'makeup' i antap, COC veliu i mas go daun gut long daunim hevi bilong 'scaling'.

 

 

Yumi mas luksave olsem kontrol bilong COC indiketa i no stretim wanpela paramita tasol i nidim gutpela menesmen wantaim planti samting olsem sait-strim filtresen sistem, wara tritmen kemikel, na blowdown volium. Taim ol i putim ol marasin bilong klinim wara olsem ol 'scale inhibitors' na 'corrosion inhibitors', 'anti-concentration capacity bilong wara i ken kamap gutpela moa, na long dispela rot inap long apim COC veliu na winim mak bilong lukautim na daunim yusim bilong wara. Insait long ol pepa bilong bid, gutpela mak bilong COC kontrol em i wanpela bikpela samting tu bilong soim 'rationality' na 'economic' bilong teknikel skim, we i save afektim stret 'competitiveness' bilong bid skim.
