Tube uye chubhu kupisa exchangers

Chigadzirwa tsananguro

Tube uye chubhu kupisa exchangers anoshandiswa zvakanyanya mukugadzirwa kwemakemikari uye doro. Iyo inonyanya kuumbwa negoko, tube sheet, kupisa kupisa chubhu, musoro, baffle uye zvichingodaro. Chinhu chinodiwa chinogona kugadzirwa nesimbi kabhoni, mhangura kana simbi isina tsvina. Panguva yekutsinhana kwekupisa, mvura inopinda ichibva mupombi yekubatanidza yemusoro, inoyerera mupombi, uye inoyerera ichibva mupombi inobuda kune imwe mugumo wemusoro, iyo inonzi divi repombi; imwe mvura inopinda kubva pakubatana kwegoko, uye inoyerera ichibva kune rumwe rutivi rwegoko. Nozzle imwe inoyerera ichibuda, inonzi shell-side shell-and-tube heat exchanger.

Chimiro chegoko uye chubhu yekupisa yekutsinhanisa iri nyore, compact uye yakachipa, asi mechanic yekuchenesa haigone kuitwa kunze kwechubhu. Iyo chubhu bundle yekupisa yekupisa yakabatana nebepa rehubhu, mapepa echubhu anosungirirwa zvakateerana kusvika kumigumo yegoko, chivharo chepamusoro chakabatana nevhavha yepamusoro, uye chivharo chepamusoro uye goko zvinopihwa mvura. pombi uye pombi yekubuda nemvura. Nhepfenyuro dzemabaffles perpendicular to the chubhu bundle dzinowanzoiswa kunze kwemachubhu egoko uye chubhu inopisa yekupisa. Panguva imwecheteyo, kuwirirana pakati pechubhu uye tube sheet uye shell yakasimba, uye kune maviri emvura ane kupisa kwakasiyana mukati uye kunze kwechubhu. Naizvozvo, kana tembiricha musiyano pakati pechubhu madziro uye madziro egoko rakakura, nekuda kwekusiyana kwekupisa kwekuwedzera kwezviviri, kushushikana kukuru kwekushisa kunogadzirwa, kuitira kuti machubhu anomonyoroka kana kusunungurwa kubva pachubhu ndiro ye. iyo goko uye chubhu yekupisa inotsinhanisa, uye kunyangwe iyo yekupisa inopisa kukuvara.

Kuti ukunde tembiricha mutsauko kushushikana, goko uye chubhu kupisa exchanger inofanira kuva tembiricha musiyano muripo mudziyo. Kazhinji, kana musiyano wetembiricha pakati pemadziro echubhu nemadziro egoko wakakura kupfuura 50 ° C, nekuda kwezvikonzero zvekuchengetedza, chubhu uye chubhu yekupisa yekutsinhana inofanira kunge iine tembiricha yekuripira mutsauko. Zvisinei, chigadziro chekubhadhara (joint yekuwedzera) inogona kushandiswa chete kana kusiyana kwekushisa pakati pegoko remadziro uye pombi rusvingo yakaderera kupfuura 60 ~ 70 ° C uye goko remvura kudzvinyirira kusina kukwirira. Kazhinji, kana iyo goko redivi kudzvanywa kuchipfuura 0.6Mpa, zvinonetsa kuwedzera uye chibvumirano nekuda kweiyo gobvu muripo mhete. Kana mhedzisiro yekusiyana kwekushisa muripo wakarasika, zvimwe zvimiro zvinofanirwa kutariswa.

Iyo eddy yazvino inopisa firimu yegoko uye chubhu yekupisa yekutsinhanisa inonyanya kutora iyo eddy yazvino inopisa firimu kupisa tekinoroji yekufambisa, iyo inowedzera kupisa kupisa mhedzisiro nekushandura fluid inofamba mamiriro. Kusvika ku10000W/m2℃. Panguva imwecheteyo, chimiro chinoona mabasa ekudzivirira kwecorrosion, kupisa kwekushisa kwepamusoro, kupikisa kwakanyanya, uye anti-scaling. Nzira dzemvura dzemamwe marudzi ezvitsinhanisi zvinopisa dziri muchimiro chekutungamira kuyerera, zvichiita kutenderera pamusoro pemachubhu ekupisa, izvo zvinoderedza convective heat transfer coefficient.
