Umuyoboro wa tube na tube

Ibisobanuro ku bicuruzwa

Guhindura ubushyuhe bwa tube na tube bikoreshwa cyane mubikorwa bya chimique na alcool. Igizwe ahanini nigishishwa, urupapuro, igituba cyo guhana ubushyuhe, umutwe, baffle nibindi. Ibikoresho bisabwa birashobora gukorwa mubyuma bya karubone bisanzwe, umuringa cyangwa ibyuma bidafite ingese. Mugihe cyo guhanahana ubushyuhe, amazi yinjira ava mumuyoboro uhuza umutwe, ugatemba mumuyoboro, ugasohoka uva mumiyoboro isohoka kurundi ruhande rwumutwe, bita uruhande rwumuyoboro; urundi ruzi rwinjira ruva muguhuza igikonoshwa, kandi rutemba ruva kurundi ruhande rwigikonoshwa. Nozzle imwe isohoka, ibyo bita shell-side shell-na-tube ubushyuhe bwo guhinduranya.

Imiterere ya shell na tube ihinduranya ubushyuhe biroroshye, byoroshye kandi bihendutse, ariko gusukura imashini ntibishobora gukorwa hanze yigituba. Umuyoboro wa tube uhinduranya ubushyuhe uhujwe nurupapuro rwigituba, amabati yigitereko asudira kumpande zombi zigikonoshwa, igifuniko cyo hejuru gihujwe nigifuniko cyo hejuru, naho igifuniko cyo hejuru hamwe nigikonoshwa gihabwa amazi inleti n'umuyoboro w'amazi. Urukurikirane rwa baffles perpendicular kuri bundle isanzwe ishyirwa hanze yigituba cya shell hamwe noguhindura ubushyuhe. Mugihe kimwe, ihuriro riri hagati yigituba nurupapuro rwigituba nigikonoshwa birakomeye, kandi hariho amazi abiri afite ubushyuhe butandukanye imbere no hanze yigituba. Kubwibyo, mugihe itandukaniro ryubushyuhe hagati yurukuta rwigitereko nurukuta rwigikonoshwa ari kinini, kubera kwaguka gutandukanye kwubushyuhe bwombi, hazavuka impagarara nini yubushuhe, kuburyo imiyoboro izahinduka cyangwa irekuwe kuva kuri plaque ya tube. igikonoshwa nigituba ubushyuhe, ndetse nubushyuhe bwangiza.

Kugirango tuneshe itandukaniro ryubushyuhe, igikonoshwa nigituba ubushyuhe bugomba kugira igikoresho cyo gutandukanya ubushyuhe. Mubisanzwe, iyo itandukaniro ryubushyuhe hagati yurukuta rwigitereko nurukuta rwigikonoshwa rurenze 50 ° C, kubwimpamvu z'umutekano, umuyoboro woguhindura imiyoboro ya tube na tube bigomba kugira ibikoresho byindishyi zubushyuhe. Nyamara, igikoresho cyindishyi (kwagura kwaguka) gishobora gukoreshwa gusa mugihe itandukaniro ryubushyuhe hagati yurukuta rwigikonoshwa nurukuta rwumuyoboro ruri munsi ya 60 ~ 70 ° C kandi umuvuduko wamazi wuruhande nturi hejuru. Mubisanzwe, iyo igitutu cyuruhande kirenze 0,6Mpa, biragoye kwaguka no gusezerana kubera impeta yuzuye. Niba ingaruka zubushyuhe butandukanye bwatakaye, izindi nzego zigomba gusuzumwa.

Filime ya eddy ishyushye ya shell na tube ubushyuhe bwo guhinduranya cyane cyane ikoresha tekinoroji ya eddy iriho ya tekinoroji yo kohereza ubushyuhe, byongera ingaruka zo guhererekanya ubushyuhe muguhindura imiterere yimikorere. Kugera kuri 10000W / m2 ℃. Muri icyo gihe, imiterere imenya imikorere yo kurwanya ruswa, kurwanya ubushyuhe bwinshi, kurwanya umuvuduko mwinshi, no kurwanya ibipimo. Imiyoboro y'amazi yubundi bwoko bwo guhanahana ubushyuhe iri muburyo bwo gutembera kwicyerekezo, ikora kuzenguruka hejuru yigituba cyo guhanahana ubushyuhe, bigabanya coefficente yubushyuhe bwa convective.
