Wanpela 'closed-cooling tower' i wok olsem wanem?

Intenel Klos Medium Saikulesen: Konveyans bilong Kor Hit Karia

Bikpela samting bilong wanpela 'closed cooling tower' em olsem, 'cooling medium' (planti taim em wara i malumalum, 'ethylene glycol solution', o spesel 'heat transfer fluid') i save raun insait long wanpela 'coil loop' we i gat 'sealed coil loop', na i no gat 'contact' wantaim win ausait o sprei wara-we em i as bilong "klos".

Long taim bilong wok, ol i save givim hotpela samting we ol i laik mekim i kol (olsem, hai-temperature samting bilong ol 'chiller' o 'industrial reactor') i go long ol 'heat exchange coils' bilong 'closed cooling tower' long rot bilong wanpela 'circulation pump'. Dispela samting i save ron oltaim insait long ol koil, na i save givim hat em i karim i go long ol wol bilong ol koil.

Ol i save wokim ol 'coil' long 'stainless steel', 'titanium alloy', o 'copper alloy', we i gat gutpela 'thermal conductivity' na 'corrosion resistance', na dispela i mekim na hat i save ron hariap long namel i go long ol wol bilong 'coil'. Bihain long 'heat transfer', 'low-temperature medium i go bek long ol ikwipmen we i kol pinis long rot bilong 'coil outlet' long go het long kisim hat, na kamapim wanpela 'continuous closed circulation'.

Bikpela samting long dispela link em long holim gut 'loop' bilong stopim 'medium leakage' o 'air infiltration', we inap long kamapim 'medium deterioration' na 'pipeline corrosion'. Olsem na, sistem i save gat wanpela 'expansion tank' (long skelim senis bilong presa), wanpela 'make-up pump' (long helpim 'medium loss'), na wanpela 'precision filter' (long rausim ol pipia).

Ekstenel Sprei na Evaporativ Hit Senis: Hit Transfer i go long Atmosfera

Ausait bilong wanpela 'cooling tower' we i pas i gat wanpela op straksa, we i save rausim hat long ol koil long rot bilong sprei wara evaporesen na win konveksen-dispela em i as bilong hat disipesen link, we i bruk long tupela step: "sprei wara saiklon" na "evaporesen + konveksen hat eksens".

Spreim wara i raun

Ol i putim wanpela sump long as bilong taua. Wanpela 'spray pump' i save putim presa long wara bilong mekim kol insait long 'sump' na i save spreim wankain long ausait bilong ol 'heat exchange coils' long rot bilong 'spray device' antap, na dispela i save kamapim wanpela wankain wara film. Sprei wara i save tatsim olgeta ausait wol bilong ol koil, na kisim hat we ol wol i save givim, na bihain i save pundaun bek insait long sump bihain long tempereja i go antap, na pinisim intanel sirkulasen bilong sprei wara. Sump i save gat wanpela 'water quality stabilizer dosing device' bilong stopim 'scaling' na 'microbial growth' insait long wara bilong sprei, we inap long bagarapim 'heat exchange efficiency'.

Evaporesen + Konveksen Hit Senis

Ol i putim wanpela 'axial flow fan' long daunbilo o sait bilong 'closed cooling tower'. Taim fan i wok, em i save pulim win i kam ausait long taua, na win i save go antap long spes namel long ol koil na wara film. Tupela kain hat senis i save kamap long dispela taim: namba wan,gutpela senis bilong hat-win i save tatsim stret wara film we i gat bikpela hat, na i save givim hat long narapela narapela tempereja; sekon,hait senis bilong hat-hap bilong wara bilong sprei i save go aut aninit long win, na i save pulim bikpela hat bilong 'vaporization' (em i save kamapim 70%-80% bilong olgeta hat i save lus), na dispela i save daunim hariap temperaja bilong ol ausait wol bilong koil.

Ol win we i hat na i wetwet i save lusim antap bilong taua, na dispela i save rausim bikpela hap bilong hat, na wara bilong sprei we i no bin kamap olsem steam i save pundaun i go bek long 'sump' bilong yusim gen. Liklik hap bilong lus bilong 'evaporation' i save kamap taim ol i givim fres wara.

Regulesen bilong volium bilong win na ol helpim sistem: Gutpela wok bilong wok gut

Long inap long ol kain kain hevi na envairomen kondisen, ol 'closed cooling towers' i gat ol samting bilong bosim win na ol narapela sistem bilong mekim wok i stap gut na yusim gut pawa:

Kontrol bilong fen we i gat senis long frikwensi bilong en: Em i save stretim spit bilong fan (o namba bilong ol fen we i wok) bihainim tempereja bilong medium long autlet bilong ol 'heat exchange coils'. Taim 'cooling load' i liklik, ol i save daunim spit bilong 'fan' bilong sevim pawa; taim ples i hat tumas (olsem, long taim bilong san), ol i save skruim spit bilong en long mekim win i go antap na mekim hat i lus.

Ol masin bilong pasim ais: Long ol ples we i kol o long taim bilong 'low-load operesen long taim bilong kol, ol samting insait long ol 'coil' inap long kamap ais bikos long liklik tempereja. Dispela sistem i gat ol samting bilong 'electric tracing', 'steam tracing', o wanpela 'circulation bypass device' bilong holim 'medium temperature' antap long 'freezing point'; long wankain taim, sprei sistem i ken senis i go long "drai operesen" (stopim sprei, dipen tasol long win konveksen bilong senisim hat) long abrusim bagarap long taua bikos wara bilong spre i ais i kamapim.

Demister design: Ol i putim wanpela 'demister' antap long taua, we inap long holim ol liklik liklik wara insait long wara bilong sprei (wantaim mak bilong holim antap long 99%). Dispela i no daunim tasol pipia wara tasol tu i pasim ol liklik wara long go aut long win, we inap long kamapim wet o korosen long envairomen.

Samting bilong olgeta wok

Wok bilong wanpela 'closed-circuit cooling tower em i olsem: hot medium i go insait long ol koil → hat i save go insait long ol wol bilong koil → wara bilong sprei i save kisim hat → win i save go aut na karim hat i go → kol medium i save kam bek.

Hot medium i save ron insait long ol 'coil' we i pas, na hat i save go insait long ol 'coil' wol i go long 'external spray water film'; win we fan i kam insait i save tatsim wara film, na karim hat i go aut long taua long rot bilong 'evaporation' na 'convection'; ol samting we i kol i go bek long ol ikwipmen bilong mekim wok gen, na wara bilong sprei i save raun planti taim insait long taua wantaim liklik hap tasol bilong lus bilong 'evaporation'.

Dispela disain i holim yet gutpela bilong 'evaporative heat dissipation' bilong ol 'open cooling tower' na tu i abrusim ol hevi bilong kontaminesen na 'scaling' we i save kamap taim 'cooling medium' i pas stret wantaim ausait wol, na i winim tupela mak bilong "hai-efisiens 'heat dissipation + medium protection'".
