Kuenzaniswa kwegoko-uye-chubhu nemhepo-zvinochinja kupisa zvakatonhorera

1. Mamiriro neSimbo reShell-uye-Tube Heat Exchangers

Shell-uye-machubhu ekushinhanisa mvura{2}}midziyo yakatonhodzwa yekutsinhanisa mvura. Chimiro chavo chine simbi, masumbu echubhu emukati, machubhu sheets, nema end caps, zvichiita kuti pave nekusimba uye{4}}kurongeka zvakanaka. Nheyo yekushanda inosanganisira kuchinjana kwekupisa pakati pemvura mbiri: imwe inoyerera mukati mechubhu bundle, asi imwe inoyerera mugomba pakati pehoko uye chubhu bundle. Mvura ndiyo musimboti wekutonhora svikiro, uye kupisa kunowanikwa kuburikidza nemadziro echubhu. Mhando dzemaumbirwo akajairika dzinosanganisira fixed tube sheet type, inoyangarara musoro mhando, uye U-tube type.

2. Mamiriro uye Musimboti weMhepo{1}}Yakatonhodzwa Heat Exchanger

Mhepo-zvinodziisa kupisa zvakatonhodzwa kazhinji kacho machubhu akacheneswa, kunyanya anoumbwa nesimbi chubhu masumbu, zvimbi zvealuminium, axial flow mafeni, nemafuremu. Havadi mvura inotonhorera; pachinzvimbo, feni inotyaira ambient mhepo kutsvaira pafinned chubhu masumbu, uye kupisa exchange cycle inopedzwa nemhepo convection kutakura kupisa kubva mvura. Chimiro chese chakareruka uye hachina zvikamu zvedunhu remvura.

1. Kunyatsoshanda uye kugadzikana kwegoko{1}uye-machubhu ekubatisa kupisa

Iyo inozvirumbidza yakakwirira uye yakanyanya kugadzikana kupisa kwekutsinhanisa kunyatsoshanda. Kupisa kwemvura kwemvura kwakakwira nekure kupfuura kwemhepo, zvichikonzera musiyano mudiki wetembiricha, kuchinjana kwekushisa kwakanyanya, uye kunyatsoita tembiricha. Iyo midziyo inochinjika kune inogara tembiricha uye yakagadzikana kushanda, isingakanganiswe nekushanduka kudiki kwekushisa kwemukati. Kunyangwe mukati me-nguva inoramba ichishanda, kushanda kwayo kwekushisa kunowora zvishoma nezvishoma, zvichiita kuti ienderane nepamusoro-mazvo, akakwirira-kuremedza zvinhu zvinoramba zvichigadzirwa. Iyo inogona zvakare kugamuchira chikamu chekuchinja kupisa kwekutamisa (condensation, vaporization) kusangana nezvinodiwa zvekutsinhana kupisa.

2. Kunyatsoshanda uye kugadzikana kwemhepo{1}}yakatonhodzwa kupisa zvinopisa

Iko kupisa kwekupisa kunenge kwakaderera, uye mhepo ine urombo hwekupisa conductivity. Pasi pemamiriro akafanana ekushanda, kushandiswa kwekushisa kwekushisa kuri 15% -20% yakaderera pane iyo yegoko uye chubhu rudzi. Kugadzikana kwekushanda kunonyanya kukanganiswa nekupisa kwe ambient. Kupisa kwakanyanya muzhizha kuchaita kuti tembiricha yekumisikidza ikwire uye kupisa kwekuchinja kuderera, zvichimanikidza kuwedzera kwemidziyo. Kudzikira tembiricha munguva yechando, mvura, sinou, uye ine huruva mamiriro ekunze zvichakanganisawo zvishoma kugadzikana kwekupisa. Iyo tembiricha yekudzora kurongeka kwakakura.

1. Kugoneka kwegoko-uye-machubhu ekuchinjisa kupisa kune akasiyana siyana ekushanda

Inokodzera kuoma kwemamiriro ekunze emuindasitiri, inozvikudza uye inoshingirira tembiricha yepamusoro, inokwanisa kutsungirira tembiricha inosvika 400 madhigirii uye kumanikidzwa kusvika ku10MPa, zvichiita kuti ikwane zvakakwana kune-kudzvanywa uye kukwirisa{3}}mamiriro ekugadzirwa kwemafuta mupetroleum, makemikari, uye maindasitiri anorema. Iyo chubhu bundle ine hombe inoyerera -chikamu, zvichiita kuti isanyanye kuvharika. Inogona kuchinjirwa kune inoora uye viscous zvinwiwa nekutsiva zvinhu zvakaita sesimbi isina simbi uye titanium, ichiratidza kusimba kwakasimba uye kusangana nekutsinhana kwekupisa zvinodiwa zveakasiyana akaomarara maindasitiri media.

2. Kuchinja kwemhepo-zvinodziya zvinodziya zvakatonhodzwa kumamiriro ekushanda akasiyana-siyana

Inokodzera tembiricha yakajairwa uye yakaderera kudzvinyirira mamiriro ekushanda, asi haigone kumirisana nekumanikidza kwakanyanya uye yakakwirira tembiricha mashandiro; inokodzera kuchinjisa-pressure fluid yakaderera. Zvinoda kuchena kwepamusoro kwepakati; viscous, tsvina-yakapfuma, kana corrosive media inogona kukonzeresa kuvharika kwefin uye kukuvara. Chakanyanya kukosha kuenderana kwayo nemvura-inoshaikwa, iri kure, uye isina kutsigirwa nzvimbo dzekupa mvura, zvichiita kuti isatadziswe nezviwanikwa zvemvura uye ichipa kusandunuka kukuru mukugadzirisa kwezvakatipoteredza.

1. Zvinodiwa zvekuisa uye nzvimbo yepasi yegoko-uye-machubhu ekubatisa kupisa

Inotora nzvimbo diki uye ine compact yakazara dhizaini. Inogona kuiswa mune zvese zvakadzika uye zvakachinjika zvigadziriso kuti zvienderane nenzvimbo diki dzewekishopu. Nekudaro, ine yakakwirira yekuisa zvinodiwa. Nzira yakakwana yekutonhodza mvura inofanira kuvakwa, kusanganisira shongwe inotonhorera, pombi yemvura inotenderera, pombi dzemvura, mavharuvhu, midziyo yekuchenesa mvura, nezvimwewo. Kuiswa kwemvura kwakaoma uye kune zvinodiwa zvakasimba pane nzvimbo yemvura uye dhizaini.

2. Zvinodiwa zvekuisa uye zvepasi zvemhepo{1}}zvinodziya zvinodziya

Hapana hurongwa hwemvura hunodiwa; inoda chete magetsi kuti ishande. Kuisa iri nyore uye nguva yekuvaka ipfupi, zvichiita kuti ikwane kunze, yakavhurika-mhepo, uye nzvimbo dzekuvakisa dziri kure. Izvo zvisingabatsiri ndezvekuti midziyo yakakura muhukuru uye inotora nzvimbo yakakura, inoda nzvimbo yakakwana yekufefetera kuti ive nechokwadi chekufambisa kwemhepo. Haikwanise kuiswa kana kushandiswa munzvimbo dzakavharirwa mukati.
