Isilinganiso sokugeleza kwe-Amonia
I-Amonia, isakhi esinobuthi nesiyingozi, ibalulekile ekusetshenzisweni kwezimboni eziningi njengokukhiqizwa kukamanyolo, uhlelo lwezimboni olupholisa kanye nokunciphisa ama-nitrogen oxide. Ngakho-ke, ukubaluleka kwayo emikhakheni eguquguqukayo kuphakamisa izimfuneko eziqinile mayelana nokuphepha, ukusebenza kahle kanye nokunemba imbala. Ukukalwa okunembayo kokugeleza kwe-ammonia ekucutshungulweni okusebenzayo kwemboni akuyona nje imfuneko yobuchwepheshe, kodwa futhi kuyimpoqo yokuphepha.
Ukukhetha imitha yokugeleza efanelekile ye-ammonia kwenza umehluko ekuphatheni izici ezihlukile zakho kokubili igesi ne-ammonia ewuketshezi kumapayipi ezimboni. Bese idatha enembile nemiphumela ethembekile efana ne-4-20mA, RS485, noma amasiginali we-pulse ingaqashelwa futhi irekhodwe ukuze kulungiswe isikhathi sangempela. Ama-opharetha ayakwazi ukuthuthukisa izinqubo ngokuhambisana namazinga okuphepha.
Ngaphezu kokulawula okunembile ezinqubweni, ukukalwa kokugeleza kwe-ammonia kuyadingeka kuzo zonke izixhumanisi ukunciphisa izingozi ezibangelwa i-NHx enobuthi, engase ibangele ukucasuka emehlweni, ikhala, umphimbo ekugxilweni okuphansi. Futhi kubangele ukuvuvukala okukhulu nokushiswa okuqhubekayo esimweni sokuchayeka okuphezulu. Ukuchayeka ku-ammonia egxilile kungase kubangele ubumpumputhe, ukwehluleka ukuphefumula ngisho nokufa.
I-Gas Ammonia vs. Liquid Ammonia
I-ammonia ye-gaseous ne-liquid iyahlukahluka ngezakhiwo ezihlukile kanye nezicelo zezimboni. Umehluko ophawulekayo phakathi kwezinhlobo ezimbili ze-ammonia uthinta kakhulu ukuphatha, ukugcinwa kanye nezixazululo zokulinganisa. I-gas ammonia yakhiwa ama-athomu e-nitrogen nama-athomu e-hydrogen, abola emazingeni aphezulu okushisa enze i-nitrogen ne-hydrogen. Ngaphezu kwalokho, i-gas ammonia ishintsha ibe yi-nitric oxide ngosizo lwe-catalyst ngaphansi kwezimo ezifanele.
I-ammonia enobuthi ewubuthi iyagqwala futhi isabela ngokuqinile lapho uswakama uma ifika emanzini nolwelwesi lwamafinyila. I-ammonium hydroxide eyakhiwe iyingozi kakhulu futhi iyingozi ezicutshini.
I-ammonia ewuketshezi ingumphumela wokuncibilika kwegesi ye-ammonia emanzini, eyaziwa njengesixazululo se-ammonia esinamanzi, okuwuketshezi olungenambala oluvuthayo olunephunga elimnandi. Ukusabela okungaba khona kokushisa kufanele kuphathwe ngokucophelela lapho i-ammonia ihlangana namanzi. I-ammonia enamanzi iyahwamuka lapho ichayeke emoyeni, ibuyele esimweni segesi. Omunye uhlamvu olwengeziwe ukuthi ingancibilika kuzincibilikisi zemvelo njengotshwala nama-ether kalula.
Izidingo Zokukala Nokulawula Ukugeleza
Njengoba kunikezwe ukugqwala nezinye izici zamakhemikhali ezihlukile ze-gas ammonia, ukuhlukahluka okufanele kubalulekile lapho kukhethwa imitha yokugeleza efanele ngaphandle kokuyekethisa ekunembeni kwayo. Ukulethwa kwe-ammonia okufanelekile kudinga amamitha okugeleza ngokunemba okuphezulu. Futhi impahla ekwazi ukumelana nokugqwala yemitha yokugeleza iyadingeka ukuze imelane nezimo ezinzima zemvelo.
Izinguquko zokusebenza ezifana nezinga lokushisa, ingcindezi kanye ne-viscosity kufanele kucatshangelwe ukuze kutholakale izilinganiso ezinzile futhi ezinembile. Isinxephezelo sezinga lokushisa siwusizo ekugcineni ukufundwa okunembile ngokuziphatha kwayo okuhlukahlukene nezinga lokushisa.
Izinselelo Zokulinganisa Igesi ye-Amonia
Sekukonke, kunezinselelo ezahlukahlukene ekulinganisweni kwegesi ne-liquid ammonia.
✤Ukuguquguquka okuphezulu nokusebenza kabusha
✤Impahla ebolayo futhi enobuthi
✤Incibilika kuma-organic solvents
✤Isinxephezelo sezinga lokushisa nengcindezi
Isetshenziswa Kanjani I-Amonia Ekukhiqizeni?
Ukusetshenziswa okugqame kakhulu kwe-ammonia e-USA kuwumthombo onamandla wenitrogen wokukhula kwezitshalo. Ingaphezu kuka-80% i-ammonia isetshenziselwa ukukhiqiza umanyolo omningi oqinile emkhakheni wezolimo. Lawo manyolo ngobuningi obuqinile ayengafakwa ngokuqondile emhlabathini noma aguqulwe abe usawoti omningi we-ammonium. Njengoba sonke sazi, ukwengezwa kwe-nitrogen kuba nomthelela ekukhuleni kokutshala okusanhlamvu okukhulu kokusanhlamvu.
Sebenzisa kahle amakhemikhali e-ammonia ahlukile ohlelweni lokupholisa izimboni. Ukushisa okunamandla kungamuncwa ku-ammonia eyigesi ngesikhathi sokuncibilika, kufinyelele injongo yokugcina amazinga okushisa aphansi endaweni evalekile. Ngakho-ke indawo engenhla ishiya i-ammonia enye yeziqandisi ezisebenza kahle kakhulu ekusebenzeni okungokoqobo.
Ngokwesibonelo, izindawo zokucubungula ukudla zidinga iziqandisi zezimboni ukuze zilawule izinga lokushisa. Izimpahla ezibolayo zihlala zisesimweni esihle ngokuhambisana nezindinganiso eziqinile mayelana nokuhlanzeka kokudla nokuphepha. Ikhethwa phakathi kwezinye iziqandisi ngokusebenza kwayo okuphezulu kokupholisa. Ngaphezu kwalokho, umthelela wayo omncane endaweni ezungezile ulandela izitayela zamanje zokunciphisa ukukhishwa kwekhabhoni nezindleko zamandla.
I-Amoniya iwushintsho lomdlalo ekwehliseni ukukhishwa kwe-nitrogen oxide. Ngokuvamile, yethulwa ukuze isabele ngama-nitrogen oxides lapho izama ukuwaguqulela ku-nitrogen yemvelo namanzi kukho kokubili ukuncipha kwe-catalytic okukhethiwe (SCR) kanye nokunciphisa okukhethiwe okungeyona i-catalytic (SNCR). I-nitrogen oxides, igalelo eliyinhloko ekungcolisweni komoya nemvula ene-asidi, iyakwazi ukuguqulelwa kokuqukethwe okungenangozi ngemva kwe-SCR ne-SNCR.
Inembileisilinganiso sokugeleza kwe-ammoniaikhula ibalulekile emigqeni ye-automation yezimboni kanye nokucubungula ukuze kugcinwe ukuhambisana nokulawula kanye nokusebenza kahle kokunciphisa i-NOx, lapho ukuchezuka okuncane kungase kuthinte ukusebenza kwesistimu kanye nemiphumela yemvelo.
Kunconywe i-Amonia Flow Meter
Thola okulungileigesi mass flow meterngeI-Lonnmeter. Ibanga elibanzi lokusebenza okuphezulu kwesilinganiso sokugeleza okuhlukahlukene nezidingo zokuhambisana negesi. Imitha yokugeleza kwenqwaba inikeza ukufundwa okuthembekile nokunembile futhi ikusiza ukuthi ulahle ukulinganisa okuphindaphindiwe okwenziwa ngesandla. Shiya o-opharetha kude nendawo enobuthi noma eyingozi, qinisekisa ukuphepha kwakho siqu ngangokunokwenzeka.
8800 Vortex Flow Meter
I-gasket-free kanye ne-clog-resistanti-vortex flow meter yegesiithuthukisa isikhathi sokusebenza futhi inciphise ukuphazamiseka okungalindelekile. Okugqamile kwayo kulele ekwakhiweni okusha kanye nenzwa ehlukanisiwe, okuvumela ukushintshwa kwezinzwa zokugeleza nezinga lokushisa ngaphandle kokuphazamisa uphawu lwenqubo.
