Ol 'closed cooling towers' i narakain tru long ol 'open cooling towers'

 

 

 

 

Olsem ol ikwipmen bilong senisim hat insait long ol indastriel prtion na ea kondisen sistem, ol 'closed cooling towers' i no wankain olsem ol 'open cooling towers' long sait bilong wok, straksa disain, pefomens karakteristiks, na aplikesen senario. Maski tupela i laik kamapim 'heat dis' na 'cooling', ol bikpela tingting bilong tupela na wok bilong tupela i narapela narapela, na dispela i save mekim wok bilong tupela i kamap long ol wok bilong tupela. Dispela em i wanpela gutpela skelim bilong tupela taipoling taua.

 

 

Bikpela samting we i soim olsem i no wankain namel long 'closed' naopim kol taua giamanlong ol wok prinsipol bilong ol, we i save makim tu ol wok bilong ol. Ol 'open cooling towers' i save yusim wanpela 'direct contact heat exchmethod': ol i save spreim wara i ron long bikpela tempereja i go antap long 'packing layer' long rot bilong wanpela 'spray system', na dispela i save kamapim wanpela liklik wara film we i save kam insait long ful kontek wantaim win we i save kamap long rot bilong 'fa dissipation' na dispela i save kamap long tupela rot: 'sensible heat exchange' namel long wara na win, na 'latent absorption' i save kamap long wara, 'evaporative latent heat' we i save kamapim samting olsem 80% bilong olgeta 'heat dissipation'. Bihain long senis bilong hat, wara we i kol i pundaun i go insait long 'bottom sump' na ol i save pamim i go bek insait long sistem bilong 'circulation'. Tasol, long taim bilong wok bilong em, wara i raun i save go stret long win, na dispela i save mekim wara i save bung wantaim das, ol pipia, na ol liklik binatang i kam long envairomen.

 

 

 

 

Tasol, 'closed cooling' em i wanpela 'indirect contact heat exchange' rot. Proses fluid we ol i laik mekim i kol i save raun insait long wanpela 'closed coil', na i no save bungim win ausait. Sprei sistem i save spreim kol wara long ausait bilong koil, na kamapim wanpela wara film. Hat bilong hai-temperature fluid insait long koil i save go long sprei wara long wol bilong tiub, na e fan i save draivim win i ron long karim hat i go long rot bilong 'evaporation' na 'convection'. Wara bilong sprei i save pundaun insait long 'sump' bilong 'circulation', na wara bilong 'process' i stap klin na i no gat ol samting nogut i kamap ausait long en. Na tu, ol 'closed cooling towers' inap long senis namel long 'full-evaporative mode, 'dry mode', na 'hybrid mode' bihainim temperaja bilong ples, na dispela i mekim na ol i ken yusim gutpela pawa na lukautim gut wara.

 

 

Long sait bilong wok bilong tupela, ol samting bilong tupela 'cooling tower' tu i no wankain. Ol 'open cooling tower' i gat wanpela isipela straksa, we i gat 'tower body', 'acking layer', 'spray system', 'sump', na 'drift eliminator'. Ol i save wokim 'packing layer' long ol PVC 'corrugated plates' wantaim bikpela 'surface ara' (inap long 200-400 skwea mita long wan wan 'cubic meter') bilong mekim wara na win i pas gut. Ol i save yusim 'drift eliminator' long daunim lus bilong wara, na 'sumply' i konektim i go long 'circulation system'. Maski em i isi long klinim, em i save kamapim ol skel na ol 'algae' i save gro.

 

 

 

 

 

 

Ol 'closed cooling tower' i gat wanpela moa kompleks straksa, we as bilong en em i wanpela 'closed coil', we ol i save wokim long 'stainless steel' o kopa, na i gat gutpela presa resistans (1.6-2.5 MPa) na 'thermal conductivity'. Antap long 'pray system', 'fan', na 'sump', ol i gat ol 'drift eliminators' bilong stopim wara bilong sprei long win i no ken karim i go. Sampela model i gat ol 'anti-freeze ais olsem ol 'electric heating tapes' bilong stretim ol ples we i no hat tumas. Bikos ol i putim koil,ol kol taua i pasi gat bikpela strong bilong win winim ol 'open cooling tower', olsem na ol fan we i stap wantaim i save antap moa.

 

 

Long sait bilong wok bilong en, tupela kain 'cooling tower' i gat ol gutpela na nogut samting. Ol 'open cooling towers' i gat ol gutpela samting olsem 'heatn efficiency', isi straksa, liklik invesmen long stat, na liklik kos bilong mentenens. Ol i ken daunim hariap tempereja bilong wara long rot bilong 'direct contact heat exchange', na dispela i mekim ol i gutpela long ol bikpela 'industrial cooling' we ol i no nidim gutpela kwaliti bilong wara. Tasol, ol i save kisim bikpela hap wara wantaim bikpela lus bilong 'evaporation', na wara i raun i save kisim doti, na i nidim wara tritmen planti taim long stopim korosen na skel.

 

 

Ol 'closed cooling tower' i gutpela long lukautim wara na stopim polusen, na ol i save yusim 30%-50% liklik wara tasol winim ol 'open cooling tower'. Proses fluid i save ron insait long wanpela 'closed loop', na i no gat 'oxidation', 'corrosion', na 'contamination', we i save mekim wok bilong ol ikwipmen i stap longpela taim moa. Ol i gutpela long mekim wok bilong mekim kol. Tasol, ol kos bilong mentenens bilong ol pastaim i antap moa, na bikos long banis bilong ol wol bilong koil, hat disipesen efisiens bilong ol i daunbilo liklik long ol open koling taua.

 

 

Ol dispela samting i soim stret ol samting bai kamap long ol. Ol i save yusim ol 'open cooling tower' long ol pawa plent, ol 'steel mill', ol 'general industrial cooling systems', na ol 'central air conditioning systems', we ol i no nidim gutpela wara na ol i nidim planti wara i raun. Ol 'closed cooling tower' i gutpela moa long ol ples we i gat bikpela kwaliti bilong wara, olsem ol masin we i gat gutpela 'precision', ol 'electronics manufacturing', na ol 'pharmaceutical/food processing' indastri, na tu ol hap we i gat sot long wara o ol ples we i gat hatpela ples. Ol i gutpela tu long mekim kol ol samting we i save bagarapim ol samting o ol samting we i gat bikpela pe olsem ol 'acid solutions' na 'ethylene glycol solutions'.

 

 

 

 

Long tok sot, ol 'closed cog tower' na 'open cooling tower' i no wankain long wok, straksa, pefomens, na ol aplikesen senario. Ol 'open cooling towers' i save lukluk long gutpela na gutpela wok bilong en, na ol 'closed cooling towers' i save lukluk long lukautim gut wara, stopim polusen, na stap gut. Long ol wok we ol i ken mekim, ol i mas makim stretpela kain bihainim ol nid olsem kwaliti bilong wara, hamas wara ol i yusim, gutpela rot bilong rausim hat, na baset bilong invesmen bilong mekim wok bilong kol sistem i wok gut na i wok gut.
