Ol i save wokim wanpela 'spiral tube heat exchanger' long rot bilong putim wanpela o moa set bilong ol 'tube' we ol i tanim insait long wanpela 'shell'. Ol samting bilong en em i wanpela liklik straksa na bikpela hap bilong kisim hat winim ol stretpela paip. Em i gat bikpela hap bilong kisim hat winim ol stretpela paip na i no gat planti hat, tasol wok bilong klinim insait long paip i hat moa. Em i ken yusim long hatim o kolim ol wara we i gat bikpela 'viscosity'.
Ol 'spiral heat exchanger' (wantaim ol 'spiral tube heat exchanger' na 'spiral plate heat exchanger') i gat narakain 'flow channel' straksa bilong ol. Em i gat bikpela gutpela samting long 'heat exchange efficiency' na spes yutilisesen. Tasol, em i gat ol hevi tu olsem 'structural complexity' na 'maintenance difficulty'. Dispela em i wanpela ditel analisis bilong ol bikpela gutpela samting na ol bikpela hevi bilong en:
Ol bikpela gutpela samting
Bikpela 'heat exchange efficiency' na bikpela 'heat transfer coefficient'
Taim wara i ron insait long 'spiral channel', strongpela 'turbulence' i save kamap aninit long wok bilong 'centrifugal force'. (Turbulent flow i ken kamap long liklik Reynolds namba, planti taim Re > 1000.) I daunim tru 'thermal resistance' bilong 'fluid boundary layer'. 'Heat transfer coefficient' i antap tru long K shell-na-tube heat exchanger (planti taim 2-3 taims bilong ol 'shell-' na 'tube heat exchanger').
Ol hot na kol wara i save ron long 'counter-current' o 'cross-flow' (ol 'spiral plate heat exchanger' em planti taim ol i save 'pure 'counter-current'). Bikpela senis long tempereja bilong 'heat exchange', ol i yusim strong moa, na sais bilong ol ikwipmen i liklik long ol wankain 'heat exchange requirements'.
2.Kompak straksa na bikpela spes yutilisesen
Eria bilong senisim hat i stap insait long 'spiral flow channel', hap bilong senisim hat long wan wan yunit volium em i 2-4 taims bilong wanpela 'shell-' na 'tube' hat eksena. Em i no save senis hariap na em i isi long klinim na lukautim (long ol spiral plet hit eksensa).
Long taim bilong 'turbulent flow', wara i gat strongpela 'scouring effect' long wol bilong paip, we inap long pasim pipia long pundaun; maski liklik hap skel i kamap, ol i ken rausim long rot bilong 'backflushing' o 'chemical cleaning'.
Ol 'spiral plate heat exchanger' i no gat ol 'dead zone' long ol 'flow channels' bilong ol, na dispela i mekim na wara i ron gut na abrusim hevi bilong bagarap we i kamap long spes namel long ol 'baffles' na 'tube bundle' insait long ol 'shell-' na '-'tube heat exchanger'.
Em inap long karim kain kain wara, olsem ol wara i gat 'viscous' (turbulence inap long daunim 'viscous resistance') na ol wara we i gat liklik namba bilong ol liklik hap (spiral flow channel i no inap long pasim isi, na ol liklik hap inap long lusim wara wantaim wara).
3.Long eneji konsumsen na liklik operesen kos:
Turbulent flow i gat liklik 'resistance losses' (sapos yumi skelim wantaim 'forced turbulence' insait long ol 'shell-' na '-' 'tube heat exchanger'), i no nidim planti pawa bilong pam, na i no yusim planti pawa long taim bilong wok longpela taim.
Em i gat wanpela kompleks straksa, em i hat long wokim, i gat ol kompleks wok bilong weldim, na i no isi long lukautim na stretim. Em i gat liklik presa-bearing kapasiti (sapos yumi skelim wantaim ol shell-na-tube heat exchanger) na em i no gat strongpela straksa: Ol spiral plet exchanger i gat liklik presa-bearing - kapasiti winim ol 'shell-' na '-' 'tube heat exchanger' (shell-na-tubeol samting bilong senisim hat cna kisim bikpela presa long rot bilong mekim sel i kamap tik na yusim ol 'high-strongpela 'tubing'. Em i no inap long yusim aninit long ol 'high-pressure kondisen (olsem presa > 10MPa).
Mi klia long ol gutpela na nogut bilong ol 'spiral wound tube heat exchanger'. Sapos yu laik kisim moa save long ol 'heat exchanger units' o yu laik baim ol, plis salim wanpela email i go long 9988xiaoshuai@gmail.com, na mipela bai bekim tok bilong yu taim mipela i lukim email bilong yu!
