Izishintshisi zokushisa zamanxeba okuvunguza zisebenza kahle kakhulu futhi zisebenza kahle kakhulu futhi zisebenza kakhulu emkhakheni we-petrochemical, ukucubungula igesi yemvelo, ubunjiniyela be-cryogenic, kanye nemikhakha yamandla. Isakhiwo sazo esiyinhloko siqukethe inqwaba yeshubhu yokushintshanisa ukushisa kwesilonda esivunguzayo, esifeza ukudluliswa kokushisa okuphumelelayo ngomklamo oyingqayizivele wejiyomethri. Ngokusekelwe ezimisweni ezihlukene zokuhlukanisa, izishintshisi zokushisa eziyisilonda ezizungezayo zingahlukaniswa zibe izinhlobo ezihlukahlukene, ngasinye sinezici zayo ezihlukile zesakhiwo, ukusebenza, nezimo ezisebenzayo.
Ukwahlukaniswa ngeTube Arangement
Izishintshi zokushisa eziyisilonda zingahlukaniswa zibe -i-helix eyodwa,{1}}i-helix{1}}ekabili, kanye -nokulungiselelwa okuningi kwe-helix ngokusekelwe endleleni yokumangisa ishubhu. Ukucushwa{4}}kwe-helix eyodwa kuvame kakhulu, okunamashubhu elimele ohlangothini olulodwa. Ilungele izinhlelo zokusebenza zengcindezi ephansi- kanye{7}}ephakathi. Ukucushwa kwe-double-helix kusebenzisa amasethi amabili{10}}ezinqwaba zamashubhu enxeba, okuthuthukisa ukuphazamiseka koketshezi futhi kuthuthukise ukusebenza kahle kokudlulisa ukushisa. Ivamise ukusetshenziselwa{12}}imidiya ye-viscosity ephezulu noma izinhlelo zokusebenza ezidinga ukudluliswa kokushisa okuthuthukisiwe. Ukulungiselelwa okuningi{14}}kwe-helix kuthuthukisa ukusetshenziswa kwesikhala futhi kulungele imiklamo yemishini ehlangene.
Ukwahlukaniswa Ngokwesilinganiso Sokucindezela
Izishintshi zokushisa kwamanxeba okuvunguza zingahlukaniswa zibe izinhlobo eziphansi-, ezimaphakathi{-, neziphezulu{2}}ezisekelwe kwingcindezi yokusebenza. Izinhlobo zengcindezi{{4}ephansi (<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) ijwayele ukusetshenziswa ezinhlelweni ezinzima ezifana nokuhlukaniswa kwe-cryogenic kanye{1}}nomfutho we-hydrogenation ophezulu. Izinqwaba zamashubhu azo zisebenzisa{3}}izinto ezinamandla kakhulu (njengensimbi yengxubevange noma i-titanium) futhi ziboshwe ngokuqina okuthuthukisiwe ukuze zimelane nezingcindezi eziphezulu.
Ukuhlukaniswa ngohlelo lokusebenza
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) izindawo ezifana nokuqhekeka kwe-petroleum kanye ne-ammonia synthesis, egcizelela ukumelana nokugqwala nokuzinza kwesakhiwo.
Ukuhlukaniswa kwezishintshi zokushisa kwamanxeba okuvunguza kubonisa ukuguquguquka kwazo ezimweni ezihlukene zokusebenza. Ngokukhetha okunengqondo, ukusebenza kahle kokusetshenziswa kwamandla kungathuthukiswa kakhulu futhi izindleko zokugcinwa kwemishini zingancishiswa, okuyisiqondiso esibalulekile sokuthuthukiswa kobuchwepheshe besimanje bokushintshanisa ukushisa kwezimboni.
