Ukuhlunga Amanzi Ane-Acidic Avela Ku-Ammonia Wash Towers – Isihlungi Sebhasikidi

I. Isimo Sokusebenza Isizinda: Izinselele Ezinzima Zoketshezi Olune-Acidic

Isihlungi esingamasentimitha angu-8 esisetshenziswa amakhasimende ase-Israel sicubungula amanzi ane-asidi avela embhoshongweni wokuwasha we-ammonia, ngenani le-pH elingaba ngu-3. Asigcini nje ngokuqukethe i-25% ammonium sulfate kodwa futhi siqukethe inani elincane lezinhlayiya ezikhiqizwa ngesikhathi sokuwasha komoya. Le ndawo ephakathi ene-asidi kakhulu futhi ebolile ibeka izidingo eziphezulu kakhulu ekumelaneni nokugqwala kanye nokuqina kwesakhiwo sezinto zokuhlunga. Ukuba khona kwe-ammonium sulfate kusheshisa ukugqwala nokuguga kwezinto zensimbi ezivamile, kuyilapho izinhlayiya ezilengayo zingabangela ukuvaleka kwangaphakathi kwesihlungi, okuthinta ukusebenza okuzinzile kwesikhathi eside kwemishini. Ngakho-ke, kubalulekile ukukhetha idivayisi yokuhlunga evumelana nezimo kakhulu.

II. Isiphakamiso Esenziwe Ngokwezifiso:Isihlungi sebhasikidi esimbozwe nge-316L + PTFE

Ngenxa yezimo zokusebenza ezinzima ezingenhla, ngemva kokuhlaziywa kobungcweti nokukhetha, sincoma ikhasimende lase-Israel ukuthi linikezeIzinto zensimbi engagqwali ezingu-316L ezihlanganiswe nesihlungi sebhasikidi esimboza i-PTFE (polytetrafluoroethylene)Izinzuzo eziyinhloko zalesi sixazululo yilezi ezilandelayo:

Okokuqala, insimbi engagqwali engu-316L, njengento evame ukusetshenziswa engagqwali emkhakheni wezimboni, inokuqukethwe okuphansi kwekhabhoni uma kuqhathaniswa nensimbi engagqwali evamile engu-316, enokumelana nokugqwala okuphezulu phakathi kwe-granular, okungamelana ngempumelelo nokugqwala kokuqala endaweni ene-asidi, okunikeza isiqinisekiso sesakhiwo esiqinile sesihlungi. Okwesibili,Ukugqoka kwe-PTFEinezici ezihlukile "zokumelana nokunganamatheli, ukumelana nokugqwala, kanye nokushisa okuphezulu", eyaziwa ngokuthi "inkosi yepulasitiki", engahlala izinzile kububanzi be-pH obungu-1-14 kuma-asidi aqinile nezisekelo eziqinile, ihlukanisa ngokuqinile ukuxhumana okuqondile phakathi kwesisombululo se-ammonium sulfate kanye ne-substrate yensimbi engagqwali, ngokuyisisekelo ixazulula inkinga yokuguguleka kwemidiya egqwalisayo emishinini, futhi yandisa kakhulu impilo yesevisi yesihlungi.

Ngesikhathi esifanayo, ukwakheka kwesakhiwo sesihlungi sebhasikidi kulungiswa ukuze kuhambisane nezidingo zokucubungula izinhlayiya eziqukethe uketshezi. Ibhasikidi yesihlungi eyakhelwe ngaphakathi isebenzisa izinto zokuhlunga ezinembe kakhulu, ezingavimba ngempumelelo inani elincane lezinhlayiya oketshezini, zivimbele ukuvaleka kwepayipi; futhi isakhiwo sebhasikidi silungele ukuhlukaniswa nokuhlanza, okunganciphisa izindleko zokugcinwa kwemishini futhi kuqinisekise ukusebenza okuqhubekayo nokuzinzile kohlelo lokuhlunga, okuhambisana kahle nezimo zokusebenza zangempela zamakhasimende.

III. Inani Lesixazululo: Ukukhetha Okuhle Kokuphepha Nokusebenza Kahle

Ezimweni zokusebenza ezinzima ze-asidi ebolile, izihlungi zensimbi engagqwali ezivamile kunzima ukumelana nokuguguleka kwendawo yokusebenzela isikhathi eside, zivame ukuvuza nokonakala, hhayi nje kuphela ukwandisa izindleko zokushintsha imishini kodwa futhi kuthinta inqubekela phambili yokukhiqiza ngenxa yokuvalwa kwemishini ukuze ilungiswe.Isihlungi sebhasikidi esimbozwe nge-316L + PTFE, ngokuvikela okubili kwezinto zokwakha kanye nokwemboza, akuxazululi nje kuphela inkinga yokugqwala kwesisombululo se-ammonium sulfate kodwa futhi kusingatha ngempumelelo ukungcola kwezinhlayiya, kufezwe iziqinisekiso ezimbili zokuvikela kanye nokusebenza kahle.

Lesi sixazululo siqinisekiswe ngezimo eziningi zokusebenza zezimboni ezifanayo futhi sinolwazi oluvuthiwe lohlelo lokusebenza, sihlinzeka ngokusekelwa okuthembekile kokuhlunga kwenqubo yokukhiqiza ikhasimende lakwa-Israyeli, sisize ikhasimende ukuthi ligweme izingozi zokugqwala kwemishini, sinciphise izindleko zokusebenza nokulungisa, futhi siyindlela engcono kakhulu ehlanganisa ukuphepha, ukusebenza kahle, kanye nokonga.
