Isimiso sokuhlunga umhlaba we-diatomaceous
Amawayini neziphuzo ezihlungiwe ngomhlaba we-diatomaceous zinokunambitheka okufanayo, azinabo ubuthi, azinazo izinto ezilengayo noma ezivuvukele, zicacile futhi zisobala, zihlungiwe kakhulu, zihlala endaweni encane, zilula, futhi kulula ukuzihambisa. Amapharamitha okulawula ayinhloko yizinto zegobolondo, ingcindezi yokusebenza kwegobolondo, ububanzi, umthamo wokwengeza, kanye namandla okugeza ngemuva.
Ubukhulu be-membrane yesihlungi buvame ukuba ngu-2-3mm, kanti usayizi wezinhlayiya zomhlabathi we-diatomaceous u-1-10 μ M. Ngemva kokuhlunga, sebenzisa amanzi, umoya ocindezelwe, noma kokubili ukuze ugeze ngemuva. Izinzuzo zokuhlunga okungenaminyango ukusebenza kahle kokwelashwa, amanzi okuhlanza amancane (ngaphansi kuka-1% wamanzi okukhiqiza), kanye nendawo encane (ngaphansi kuka-10% wendawo evamile yesihlungi sesihlabathi). Uma kuqhathaniswa nesihlungi sekhekhe likakotini esidala, sinezinzuzo ezisobala: ukonga amandla okungu-92%, ukulahlekelwa yiwayini okungu-90%, ukonga izindleko zemishini okungu-2/3, kanye nabasebenzi bokukhiqiza abancishiswa ngo-3/4. Ngakho-ke siyini isimiso ngemuva kokusetshenziswa kwaso?
Umgomo wokuhlunga umhlaba we-diatomaceous ukuhlunga uketshezi. Ngaphansi kwesenzo sokucindezela kwephampu, lungena ekamelweni lokuqoqa ngokusebenzisa ungqimba lwangaphambi kokufaka. Izinhlayiya nama-polymer ayabanjwa kungqimba lwangaphambi kokufaka, bese uketshezi olucacisiwe lungena ekamelweni lokuqoqa bese lugeleza luphume esitsheni nge-axis ephakathi. Isihlungi siqukethe isikrini sokuhlunga, isikrini sokusekela, kanye nohlaka lwangaphandle. Ingxenye ngayinye yesihlungi iyipayipi elinezimbobo njengohlaka lwamathambo, eligoqwe ngocingo lwensimbi futhi limbozwe nge-diatomaceous earth coating ebusweni. Ingxenye yesihlungi inamathele ku-diaphragm, kanti izingxenye ezingaphezulu nezingezansi ze-diaphragm yigumbi lamanzi angavuthiwe kanye negumbi lamanzi elihlanziwe. Umjikelezo wonke wokuhlunga uhlukaniswe ngezinyathelo ezintathu: ukubeka i-membrane, ukuhlunga, kanye nokugeza ngemuva.
Izindleko eziphansi zokuhlunga umhlaba nge-diatomaceous: ukusetshenziswa kwamanzi: ukusetshenziswa kwamanzi okugeza ngemuva kungu-1/10 walokho kwezihlungi zesihlabathi; Ukusetshenziswa kwamandla: Umthwalo wamandla ophelele wegumbi lomshini eliguqulwayo le-A-1 cishe u-3/5 wamandla ophelele wegumbi lomshini wokuhlunga wesilinda sesihlabathi wendabuko; Umthamo: Ngesikhathi sokuhlunga, kufanele kufakwe egumbini lomshini lohlobo lwe-A-1, ngomthamo ongu-0.2kg ngemitha yesikwele yendawo yokuhlunga ngomjikelezo wokuhlunga.
Ngendlela yokuhlunga umhlaba we-diatomaceous, umhlaba we-diatomaceous ngokwawo unezimbobo ezincane zemvelo eziningi, kanti izimbobo ezingajwayelekile kungqimba yesihlungi zinde futhi zisakazeke kakhulu kulo lonke ungqimba lwekhekhe, ezingamunca futhi zifake izinhlayiya ezincane kakhulu, ngaleyo ndlela zithuthukise ikhwalithi yokuhlunga. Ukuhlunga kuqukethe izingxenye ezimbili: ukuhlunga kanye nokumunca. Lapho isebenza, umhlaba we-diatomaceous uhlukaniswe waba yi-pre coating kanye nengqimba yesihlungi emunca endwangu yesihlungi ngaphandle kwesihlungi, kwakha ungqimba lwekhekhe lesihlungi olungacindezeleki olunezimbobo ezincane eziningi eziyinkimbinkimbi nezihlanganayo. Ngesikhathi sokuhlunga, ukungcola okukhulu ku-filtrate kubhajwe ebusweni bangaphandle bengqimba yekhekhe lesihlungi ngenxa yokungakwazi ukudlula ezimbobeni ezincane zesihlungi, okubizwa ngokuthi inqubo yokuhlunga. Izinhlayiya ezincane zingena kungqimba lwekhekhe lesihlungi futhi zimunca futhi zibanjwe ezimbobeni ezigobile neziyinkimbinkimbi, okubizwa ngokuthi inqubo yokuhlunga. Ukuze kutholakale isisombululo esicacile sokungena. Lapho ingcindezi yokuhlunga yesihlungi ikhuphuka, kubonisa ukuthi ezinye zezimbobo zesihlungi kungqimba yesihlungi ivaliwe. Ngalesi sikhathi, kwakheka ungqimba olusha lokuhlunga ngokufaka umhlaba we-diatomaceous emshinini wokuhlunga ukuze kuqhutshekwe nokuhlunga. Lapho iningi lama-pores kungqimba lwekhekhe lokuhlunga livinjiwe futhi izinga lokuhlunga lehla, susa ikhekhe lokuhlunga, umboze ungqimba olusha lwekhekhe lokuhlunga kusengaphambili, bese uhlunga. Uma ubheka ukuhlungwa kwamakhekhe okuhlunga ahlukaniswe ngezingqimba ezimbozwe ngaphambili nezihlungi, kungabonakala ukuthi iningi lokungcola lihlungwa ngokuvinjelwa futhi livaleleke ngaphandle kwama-pores okuhlunga, kanti ukungcola okuncane kakhulu okufakwe ngaphakathi kwama-pores.
