Wanem kain 'cooling tower' i gutpela tru?

 

Long lukluk bilong ol 'core heat exchange principles', 'cross-flow closed-circuit cooling tower' i adoptim wanpela"kros-win i ron + klostu-seket i raun"disain: wara bilong mekim kol i ron insait long ol 'coil pipe' we i no gat 'contact' wantaim win ausait, na win ausait i save ron stret long ol 'coil pipe' na 'spray water layer', na kamapim wanpela 'tri-feis 'heat exchange system' (gas-likwid-solid). Dispela straksa i save mekim 'heat exchange area utilization rate' i go antap long moa long 30%, na ol i ken bosim gut 'cooling temperature difference' insait long 5-8 digri, we i gutpela moa long 8-12 digri bilong ol 'open-circuit cooling towers. Long wankain taim, 'closed-circuit circulation i stretim olgeta hevi bilong 'scaling', 'corrosion', na 'water quality pollution' we i save kamap long ol 'open-circuit towers. Ol i skruim wok bilong klinim ol 'coil pipe' i go inap long 12-pela mun, na 'heat exchange efficiency efficiency atenuation rate' bilong en i no winim 5 pesen. Tasol, ol open-seket taua i ken kisim wanpela 'heat exchange efficiency attenuation' inap long 20% ​​insait long 6-pela mun bikos long 'scaling'.

 

 

 

Long sait bilong yusim gut eneji, 'cross-flow closed-circuit cooling tower i gat ol gutpela samting tru. Kros-flo disain bilong en i save daunim tru 'static pressure loss' bilong fan, na sapot hai-efisiensi veriebol-frikwensi fan i save sevim 25%–30% moa eneji winim ol fan bilong ol tradisenel kaunta-flo kol taua. Na tu, dispela model inap long stretim spit bilong fen na stat/stop bilong sprei pam bihainim trupela 'cooling load'. Koefisen bilong pefomens (COP) aninit long hap lod kondisen inap long kamap moa long 4.5, tasol COP bilong ol open-seket kol taua em i save kamap 2.8-3.2 tasol. Long wanpela 'cooling water flow rate' bilong 1,000 m3/h, 'cross-flow closed-circuit cooling tower inap long sevim moa long 100,000 yuan long pawa kos long wanwan yia, na bihainim gut ol lo bilong lukautim na daunim yusim bilong pawa insait long indastrial sekta.

 

 

Long lukluk bilong O&M na sevis laip, 'cross-flow closed-circuit cooling tower i gat liklik pe tasol. Closed-circuit circulation i save daunim yusim bilong ol wara kwaliti tritmen kemikel, wantaim kemikel kos i makim 1/3 tasol bilong ol open-circuit taua. Long wankain taim, ol 'sealed coil pipes' i no gat hevi long 'blockage', na dispela i daunim wok bilong O&M long 60%. Sevis laip bilong dispela ikwipmen inap long 20 yia, we em i 8-10 yia moa long ol open-seket taua. Na tu, 'cross-flow structure' bilong en i mekim na taua i no antap tumas, na dispela i daunim spes bilong putim long 25%, na dispela i mekim em i gutpela moa long ol liklik 'layout' insait long ol woksop o antap long rup.

 

 

Yumi mas luksave olsem namba wan invesmen kos bilong ol 'cross-flow closed-circuit cooling towers em i 15%-20% antap long ol open-circuit towers. Tasol, long rot bilong sevim mani long eneji kos na O&M kos, ol i ken kisim bek dispela invesmen insait long 2-3 yia. Long ol simpol indastriel senario wantaim liklik lod na bikpela das konsentresen, ol open-seket taua i gat sampela kos-ifektiv advantej yet. Tasol, long lukluk bilong wok longpela taim na bikpela laik bilong 'high-efficiency cooling, 'cross-flow closed-cooling tower em i nambawan gutpela samting insait long indastrial fil.
