I-spiral tube exchanger heat exchanger yenziwa ngokubeka enye okanye iiseti ezininzi zeetyhubhu zinxeba kwi-spiral shape ngaphakathi kwegobolondo.Iimpawu zayo ziquka isakhiwo esihlangeneyo kunye nommandla omkhulu wokudlulisa ubushushu kunemibhobho ethe tye.Inommandla omkhulu wokudlulisa ukushisa kunombhobho ochanekileyo kunye nokunciphisa uxinzelelo lwe-thermal, kodwa ukucoca ngaphakathi kombhobho kunzima kakhulu. Ingasetyenziselwa ukufudumeza okanye ukupholisa ulwelo olune-viscosity ephezulu.
Izitshintshi zobushushu ezijikelezayo (kubandakanya i-spiral tube exchanger heat exchangers kunye ne-spiral plate heat exchangers) zibonakaliswe ngesakhiwo sazo esisodwa somjelo wokuhamba.Unenzuzo ebalulekileyo ekusebenzeni ngokutshintshisana kobushushu kunye nokusetyenziswa kwendawo.Nangona kunjalo, ikwanayo imida enjengobunzima besakhiwo kunye nobunzima bokugcina.Olu lulandelayo luhlalutyo olucacileyo lweenzuzo zalo eziphambili kunye nokungalunganga okuphambili:
1.Izinto eziluncedo ezingundoqo
Ukutshintshana kobushushu obuphezulu kunye ne-coefficient yokudlulisa ukushisa okukhulu
Xa ulwelo luhamba ngaphakathi kumjelo ojikelezayo, isiphithiphithi esinamandla senziwa phantsi kwentshukumo yamandla ecentrifugal. 2-3 amaxesha okweqokobhe{7}}kunye-nezitshintshi zobushushu ityhubhu).
Ulwelo olushushu nolubandayo luhamba kwikhawuntara{{0}yangoku okanye{1}}ukuqukuqela (ipleyiti yokutshintshiselana kobushushu ikholisa ukusulungeka{2}yangoku).Umahluko omkhulu wamaqondo obushushu,Amandla asetyenziswa ngokufanelekileyo, kwaye ubungakanani besixhobo buncinci ngokweemfuno zokutshintshiselana kobushushu.
2.Isakhiwo esibambeneyo kunye nokusetyenziswa kwendawo ephezulu
Indawo yokutshintshiselana kobushushu igxininiswe kumjelo wokuqukuqela ojikelezayo, Indawo yokutshintshiselana kobushushu ngeyunithi nganye yi-2-izihlandlo ezi-4 zeqokobhe{2}}kunye netyhubhu yokutshintshiselana kobushushu.
Kwi-turbulent flow flow, i-fluid inefuthe eliqinileyo lokucoca eludongeni lombhobho, olunokuthi luthintele ngokufanelekileyo ukuchithwa kokungcola; nokuba umlinganiselo omncinci wezinga wenziwe, unokususwa ngokubuyisela umva okanye ukucocwa kweekhemikhali.
Izitshintshi zobushushu kwipleyiti eSpiral azinazowuni zifileyo kwimijelo yazo yokuhamba, ziqinisekisa ukuhamba kolwelo okufanayo kwaye zinqanda ingxaki emdaka ebangelwa ngumsantsa phakathi kweebhafu kunye netyhubhu kwiqokobhe{0}}kunye{1}}nezitshintshi zobushushu ityhubhu.
Iyakwazi ukusingatha iintlobo zeentlobo ze-fluid, ezibandakanya i-viscous fluids (i-turbulence inokunciphisa ukuchasana kwe-viscous) kunye ne-fluid equkethe inani elincinci lamasuntswana (i-spiral flow channel ayivalwanga lula, kwaye amasuntswana angakhutshwa nge-fluid).
3.Ukusetyenziswa kwamandla aphantsi kunye neendleko zokusebenza eziphantsi:
Ukuqukuqela kwesiphithiphithi kunelahleko yokuxhathisa okuphantsi ngokwentelekiso (xa kuthelekiswa nesiphithiphithi esinyanzelweyo kwiqokobhe{0}}kunye{1}}nezitshintshi zobushushu ityhubhu), kufuna amandla empompo amancinci, kwaye zisebenzisa amandla amancinci ngexesha{2}}lokusebenza kwexesha elide.
Inolwakhiwo oluntsonkothileyo, kunzima ukuyivelisa, ibandakanya iinkqubo zokuwelda ezintsonkothileyo, kwaye ayilunganga ukuyigcina kunye nokulungiswa. Uxinzelelo olunyiniweyo-ukuthwala umthamo (xa kuthelekiswa neqokobhe{2}}kunye{3}}nezitshintshi zobushushu ityhubhu) kwaye zinyanzelwa ngamandla olwakhiwo: Ubushushu bepleyiti yeSpiral budla ngokuba noxinzelelo oluphantsi{4}{5}ithwele iqokobhe lobushushu} (iqokobhe -kunye{8}}netyhubhuizitshintshi zobushushu cUkufumana uxinzelelo oluphezulu ngokujiya iqokobhe kunye nokusebenzisa-ityhubhu yamandla aphezulu).Usetyenziso lulinganiselwe phantsi{2}}kweemeko zoxinzelelo oluphezulu (ezifana noxinzelelo > 10MPa).
Oku kungasentla kukuqonda kwam iingenelo kunye nokungalunganga kwi-spiral isilonda sotshintshiselwano sobushushu.Ukuba ungathanda ukufunda ngakumbi malunga neeyunithi zokutshintsha ubushushu okanye unomdla wokuzithenga,Nceda uthumele i-imeyile ku- 9988xiaoshuai@gmail.com, kwaye siya kukuphendula ngokukhawuleza xa sibona i-imeyile yakho!
