Tlhaloso ea Sehlahisoa

Lisebelisoa tsa mocheso oa li-tube le li-tube li sebelisoa haholo tlhahiso ea lik'hemik'hale le joala.Haholo-holo e entsoe ka khetla, letlapa la tube, tube ea phapanyetsano ea mocheso, hlooho, baffle joalo-joalo.Thepa e hlokahalang e ka etsoa ka tšepe e hlakileng ea carbon, koporo kapa tšepe e sa hloekang.Nakong ea phapanyetsano ea mocheso, mokelikeli o kena ho tloha phala e kopanyang ea hlooho, o phalla ka phala, 'me o phalla ho tsoa phala e tsoang karolong e 'ngoe ea hlooho, e bitsoang lehlakore la pipe;mokelikeli o mong o kena ho tsoa ho hokahaneng ha khetla, 'me o phalla ho tloha pheletsong e 'ngoe ea khetla.Nozzle e le 'ngoe e tsoa, ​​e bitsoang shell-side shell-and-tube heat exchanger.

Sebopeho sa khetla le mocheso oa mocheso oa tube o batla o le bonolo, o kopane ebile o theko e tlaase, empa ho hloekisa ka mechine ho ke ke ha etsoa ka ntle ho tube.Sekoahelo sa tube ea mocheso o kopantsoeng le letlapa la tube, maqephe a li-tube a kopantsoe ka ho latellana ho ea lipheletsong tse peli tsa khetla, sekoahelo se ka holimo se kopantsoe le sekoahelo se ka holimo, 'me sekoahelo se ka holimo le khetla li fanoa ka mokelikeli. e kenang le phala e ntšang metsi.Letoto la li-baffles perpendicular to tube bundle hangata li kenngoa ka ntle ho li-tubes tsa khetla le mocheso oa mocheso oa tube.Ka nako e ts'oanang, kamano pakeng tsa tube le tube sheet le khetla e thata, 'me ho na le maro a mabeli a nang le mocheso o fapaneng ka hare le ka ntle ho tube.Ka hona, ha phapang ea mocheso pakeng tsa lebota la tube le lerako la khetla e le khōlō, ka lebaka la ho atolosoa ha mocheso o fapaneng oa bobeli, ho tla hlahisoa khatello e kholo ea mocheso, e le hore li-tubes li sothe kapa li lokolloe ho tloha poleiti ea tube. khetla le mochine oa mocheso oa tube, esita le tšenyo ea mocheso oa mocheso.

E le ho hlōla khatello ea maikutlo ea mocheso, khetla le mochine oa mocheso oa tube li lokela ho ba le sesebelisoa sa matšeliso a fapaneng a mocheso.Ka kakaretso, ha phapang ea mocheso pakeng tsa lebota la tube le lerako la khetla e kholo ho feta 50 ° C, ka mabaka a tšireletso, tube le mocheso oa mocheso oa tube li lokela ho ba le sesebelisoa sa matšeliso a phapang ea mocheso.Leha ho le joalo, sesebelisoa sa matšeliso (lenonyeletso la ho atolosa) se ka sebelisoa feela ha phapang ea mocheso pakeng tsa lerako la khetla le lerako la phala e ka tlaase ho 60 ~ 70 ° C 'me khatello ea lehlakoreng la khetla ha e phahame.Ka kakaretso, ha khatello ea lehlakoreng la khetla e feta 0.6Mpa, ho thata ho hola le ho hola ka lebaka la selikalikoe sa mats'eliso.Haeba phello ea matšeliso a phapang ea mocheso e lahlehile, mehaho e meng e lokela ho nkoa.

Filimi ea hona joale ea eddy e chesang ea khetla le mochini oa mocheso oa tube haholo-holo o amohela theknoloji ea ho fetisa mocheso oa filimi ea eddy, e eketsang phello ea ho fetisa mocheso ka ho fetola boemo ba mokelikeli.Ho fihla ho 10000W/m2℃.Ka nako e ts'oanang, sebopeho se hlokomela mesebetsi ea ho hanyetsa kutu, ho hanyetsa mocheso o phahameng, ho hanyetsa khatello e phahameng, le ho thibela ho fokotseha.Likanale tsa mokelikeli tsa mefuta e meng ea li-exchangers tsa mocheso li na le mokhoa oa ho phalla, ho etsa potoloho holim'a li-tubes tsa phapanyetsano ea mocheso, e leng ho fokotsang mocheso oa mocheso oa convective.
