Ukwakhiwa kwensimbi ye-Tubesheet ye-Heat Exchanger
Ekubalweni komklamo wezishintshi zokushisa zeshidi leshubhu eliqinile, uma kukhona isimo lapho ukucindezeleka kwe-axial kwegobolondo, ukucindezeleka kwe-axial kweshubhu lokushintshanisa ukushisa, noma amandla okudonsa phakathi kweshubhu lokushintshanisa ukushisa neshidi leshubhu kungakwazi ukuhlangabezana nezidingo zamandla (noma ukuzinza), kuba nesidingo sokufaka ijoyinti lokunweba. Kwezinye izimo, ngemva kokunquma ukujiya kweshidi leshubhu, amandla eshidi leshubhu angase anganeli ngaphandle kwejoyinti lokunweba. Kodwa-ke, ngokungeza ijoyinti lokunweba, ukujiya kweshidi leshubhu kungase kuhlangabezane nezidingo. Ezimweni ezinjalo, isinqumo sokufaka ijoyinti lokunweba kufanele sisekelwe ekuhlolweni okuphelele kokusetshenziswa kwezinto, ubunzima bokukhiqiza, ukuphepha, kanye nemiphumela yezomnotho.
Uhlobo oluvame ukusetshenziswa lwejoyinti lokunweba kuma-expansion ashintshwayo eshidi lamashubhu yijoyinti lokunweba elinomfanekiso ka-U, eliqinile, elilula ngesakhiwo, linezakhiwo ezinhle zokubuyisela, futhi lingabizi kakhulu. Njengoba ubukhulu bemishini yamakhemikhali nezitshalo zikagesi bukhula, ububanzi bamashubhu sebube bukhulu, kanti ububanzi obungu-4m kuya ku-5m buvamile. Amashubhu amakhulu abonakala ngenani elikhulu lemigodi emincane ehlanganisiwe, ejulile enezidingo zokunemba okuphezulu nokuhlanzeka.
Amashidi eshubhu asetshenziswa kabanzi ezimbonini ezifana nezishintshi zokushisa zamagobolondo namashubhu, ama-boiler, imikhumbi yokucindezela, ama-turbine, kanye nezinhlelo ezinkulu zokupholisa umoya eziphakathi. Asetshenziswa kakhulu ukusekela nokulungisa amashubhu asezitsheni zamakhemikhali, njengezivishintshi zokushisa zamagobolondo namashubhu, imikhumbi yokucindezela, ama-boiler, ama-condenser, izinhlelo zokupholisa umoya eziphakathi, ama-evaporator, kanye nezitshalo zokususa usawoti emanzini olwandle. Izinto zensimbi zamashubhu ashibhu azinikezi nje kuphela ukuqina okuphezulu kodwa futhi nezakhiwo ezinhle kakhulu zokuhambisa ukushisa.
Ngesikhathi sokwenziwa kwezishintshi zokushisa zegobolondo ne-tube, ukushisela kweshidi leshubhu nama-tube ngokuvamile kwenziwa kusetshenziswa ukushisela kwe-arc yensimbi evikelwe ngesandla, okuholela ekubeni khona kwamaphutha esimweni sokushisela, njengezimbobo, ama-pores, kanye nezinto ezifakiwe, kanye nokusatshalaliswa okungalingani kokucindezeleka kokushisela. Uma kusetshenziswa, izingxenye zeshidi leshubhu zivame ukuxhumana namanzi okupholisa ezimbonini, okungase kubangele ukugqwala kweshidi leshubhu nama-weld ngenxa yokungcola, usawoti, amagesi, kanye nama-microorganisms akhona emanzini okupholisa ezimbonini—lokhu kwaziwa ngokuthi ukugqwala kwe-electrochemical.
Ucwaningo lubonisa ukuthi amanzi ezimboni, kungaba ngamanzi ahlanzekile noma asolwandle, aqukethe ama-ion ahlukahlukene kanye nomoya-mpilo oncibilikisiwe, kanti ukuhlukahluka kokuhlushwa kwama-ion e-chlorine kanye nomoya-mpilo kudlala indima ebalulekile esimweni sokugqwala kwezinsimbi. Ngaphezu kwalokho, ubunzima besakhiwo sensimbi bungathinta nesimo sokugqwala. Ngakho-ke, izinhlobo eziyinhloko zokugqwala kwama-tube sheet kanye nama-tube welds ukugqwala okunezimbobo kanye nokugqwala kwe-crevice.
Ngiyethemba ukuthi lokhu kuhumusha kuzodlulisela ngokunembile ulwazi lobuchwepheshe olunikezile.
