Izigcwalisi ngokuvamile zibhekisela ezintweni ezigcwaliswa kwezinye izinto.
Ebunjiniyela bamakhemikhali, ukupakisha kubhekisela ezintweni eziqinile ezingasebenzi ezifakwe emibhoshongweni epakishiwe, njengezindandatho ze-Pall nezindandatho ze-Raschig, njll., umsebenzi wazo uwukukhulisa indawo yokuxhumana enoketshezi lwegesi nokubenza baxubane ngokuqinile.
Emikhiqizweni yamakhemikhali, izigcwalisi, ezaziwa nangokuthi izigcwalisi, zibhekisela ezintweni eziqinile ezisetshenziselwa ukuthuthukisa ukucutshungulwa, izakhiwo zemishini zemikhiqizo kanye/noma ukunciphisa izindleko.
Emkhakheni wokwelashwa kwendle, isetshenziswa ikakhulukazi enqubweni ye-oxidation yokuxhumana, futhi ama-microorganisms azoqoqana ebusweni bokugcwalisa ukuze kwandiswe ukuthintana kwendawo yokukhucululwa kwendle futhi alulaze indle.
Izinzuzo: isakhiwo esilula, ukwehla komfutho omncane, ukwenziwa lula ngezinto ezingezona insimbi ezikwazi ukumelana nokugqwala, njll. Ilungele ukumuncwa kwegesi, i-vacuum distillation kanye nokuphatha uketshezi olubolayo.
Ukungalungi: Uma intamo yombhoshongo ikhula, izobangela ukusabalalisa okungalingani kwegesi noketshezi, ukuthintana okungalungile, njll., okuholela ekwehleni kokusebenza kahle, okubizwa ngokuthi umphumela wokukhulisa.Ngesikhathi esifanayo, umbhoshongo ogcwele unezinkinga zesisindo esinzima, izindleko eziphezulu, ukuhlanzwa nokugcinwa okunzima, nokulahlekelwa okukhulu kokupakisha.
1. Ukupakisha indandatho ye-pall
Ukupakishwa kweringi ye-Pall kuwukuthuthuka kwendandatho ye-Raschig.Imigqa emibili yezimbobo zamafasitela angunxande ivulwa odongeni oluseceleni lwendandatho ye-Raschig.Olunye uhlangothi lodonga olusikiwe lwendandatho lusaxhunywe odongeni, kanti olunye lugobile eringini., okwakha i-lobe yolimi ephumela ngaphakathi, futhi izinhlangothi ze-lingual lobes zidlulana maphakathi neringi.
Ngenxa yokuvulwa kodonga lwendandatho ye-Pall, izinga lokusebenzisa indawo yangaphakathi kanye nengaphakathi lendandatho lithuthukiswa kakhulu, ukumelana nokugeleza komoya kuncane, futhi ukusatshalaliswa koketshezi kufana.Uma kuqhathaniswa nendandatho ye-Raschig, ukugeleza kwegesi kwendandatho ye-Pall kunganyuswa ngaphezu kwe-50%, futhi ukusebenza kahle kokudlulisa okuningi kungakhuphuka cishe ngama-30%.I-Pall ring isetshenziswa kakhulu ukupakisha.
2. Ukupakisha indandatho yesinyathelo
Ukupakishwa kwendandatho enezitebhisi kuwukuthuthuka ngaphezu kweringi ye-Pall ngokunciphisa ukuphakama kweringi enyathelayo ibe uhhafu futhi wengeze i-flange ecijile engxenyeni eyodwa uma kuqhathaniswa neringi ye-Pall.
Ngenxa yokunciphisa isilinganiso se-aspect ratio, indlela evamile yegesi ezungeze udonga lwangaphandle lokupakisha incishisiwe kakhulu, futhi ukumelana kwegesi okudlula ungqimba lokupakisha kuyancipha.I-tapered flanging ayikhulisi nje amandla emishini yesigcwalisi, kodwa futhi yenza izigcwalisi zishintshe kusuka koxhumene nomugqa kuya endaweni yokuxhumana, okungagcini nje ukwandisa isikhala phakathi kwama-fillers, kodwa futhi kube indawo yokuqoqa nokuhlakaza ukuze uketshezi lugeleze eduze nomgwaqo. ubuso be-filler., engakhuthaza ukuvuselelwa kwendawo yefilimu ewuketshezi, enenzuzo ekuthuthukiseni ukusebenza kahle kokudluliswa kwenqwaba.
Ukusebenza okuphelele kwendandatho enesitebhisi kungcono kunokweringi ye-Pall, futhi isiphenduke inhle kakhulu yokupakishwa kwe-annular esetshenzisiwe.
3. Ukupakisha isihlalo sesihlalo sensimbi
Ukupakisha isihlalo sesihlalo sendandatho (okwaziwa nge-Intalox phesheya) wuhlobo olusha lokupakisha oluklanywe kucatshangelwa izici zezakhiwo ze-annular kanye nezihlalo zesihlalo.Ukupakishwa ngokuvamile kwenziwa ngezinto zensimbi, ngakho-ke kubizwa nangokuthi i-metal ring saddle packing.
Ukupakishwa kwesihlalo sehhashi kwaminyaka yonke kuhlanganisa izinzuzo zokupakishwa kwesihlalo sonyaka kanye nokupakishwa kwesihlalo, futhi ukusebenza kwakho okuphelele kungcono kunokwendandatho ye-Pall nendandatho enyathelwe, futhi kusetshenziswa kakhulu ekupakisheni kwenqwaba.
