Spiral ronda heat exchangers inoshanda zvakanyanya uye compact heat exchangers anoshandiswa zvakanyanya mu petrochemical, gasi rechisikigo kugadzirisa, cryogenic engineering, uye zvikamu zvesimba. Chimiro chavo chepakati chine spirally ronda kupisa kwekuchinjana chubhu bundle, iyo inowana inobudirira kupisa kupisa kuburikidza neyakasiyana geometric dhizaini. Zvichienderana neakasiyana maratidziro emhando, spiral ronda rekutsinhanisa rinogona kukamurwa kuita mhando dzakasiyana, imwe neimwe iine yayo yakasarudzika maitiro, kuita, uye anoshanda mamiriro.
Kurongwa neTube Arrangement
Spiral ronda heat exchanger inogona kuiswa muchikamu che-helix, kaviri-helix, uye akawanda-helix magadzirirwo zvichienderana nechubhu inomonereka nzira. Iyo imwe-helix configuration ndiyo inonyanya kufarirwa, ine machubhu akakuvara munzira imwechete. Yakakodzera kune yakaderera- uye yepakati-mashandisirwo epressure. Iyo kaviri-helix configuration inoshandisa seti mbiri dze counter{10}}wound tube bundles, inonatsiridza kuvhiringika kwemvura uye kunatsiridza kupisa kwakanaka. Inowanzo shandiswa pa{12}}viscosity media kana maapplication anoda kuwedzerwa kupisa. Iyo yakawanda-helix gadziriso inokwenenzvera mashandisirwo enzvimbo uye inokodzera magadzirirwo emidziyo yekombuta.
Classification by Pressure Rating
Spiral ronda heat exchanger inogona kuiswa muzvikamu zvakaderera-, zvepakati-, nepamusoro-mhando dzepressure zvichienderana nekushanda nesimba. Mhando dzepressure yakaderera{{4}<1.6 MPa) are typically used in gas pretreatment or cryogenic systems; medium-pressure types (1.6–10 MPa) are widely used in conventional chemical processes; and high-pressure types (>10 MPa) anowanzo shandiswa mukuda maapplication akaita se cryogenic separation uye high-pressure hydrogenation. Machubhu mabundle avo anoshandisa-zvekusimba zvakanyanya (senge alloy steel kana titanium) uye anokuvadzwa nekusimba kwakakwenenzverwa kuti akwanise kushingirira.
Classification by Application
In industrial applications, spiral wound heat exchangers can be categorized as conventional process, cryogenic, and high-temperature and high-pressure types. Conventional process types are used for general heat exchange needs, such as hot water or low-pressure steam systems. Cryogenic types are designed for ultra-low-temperature media such as liquefied natural gas (LNG) or liquid nitrogen, utilizing specialized insulation and cryogenic materials. High-temperature and high-pressure types serve high-temperature (>400°C) and high-pressure (>20 MPa) nharaunda, dzakadai sepetroleum kupaza uye ammonia synthesis, inosimbisa kushora uye kugadzikana kwechimiro.
The classification of spiral ronda heat exchangers inoratidza kuchinjika kwavo kune akasiyana ekushanda mamiriro. Kuburikidza nesarudzo inonzwisisika, simba rekushandisa simba rinogona kuvandudzwa zvakanyanya uye mutengo wekugadzirisa zvigadziriso unogona kudzikiswa, inova yakakosha danho rekusimudzira tekinoroji yemazuva ano maindasitiri ekutsinhanisa kupisa.
