Ukulinganiswa Kokugeleza Kwe-Ammonia

I-Amonia, inhlanganisela enobuthi neyingozi, ibaluleke kakhulu ekusetshenzisweni kwezimboni eziningi njengokukhiqiza umanyolo, uhlelo lokupholisa lwezimboni kanye nokunciphisa ama-nitrogen oxides. Ngenxa yalokho, ukubaluleka kwayo emikhakheni ehlukahlukene kuphakamisa izidingo eziqinile zokuphepha, ukusebenza kahle kanye nokunemba. Ukulinganisa ngokunembile ukugeleza kwe-ammonia ekucutshungulweni kwezimboni okusebenzayo akuyona nje imfuneko yobuchwepheshe, kodwa futhi kuyimfuneko yokuphepha.

Ukukhetha imitha yokugeleza efanele ye-ammonia kwenza umehluko ekuphatheni izakhiwo ezihlukile ze-ammonia yegesi kanye ne-ammonia ewuketshezi emapayipini ezimboni. Ngemuva kwalokho idatha enembile kanye nemiphumela ethembekile efana ne-4-20mA, RS485, noma amasignali e-pulse kungaqashwa futhi kuqoshwe ukuze kulungiswe ngesikhathi sangempela. Abaqhubi bayakwazi ukwenza ngcono izinqubo ngokuhambisana nezindinganiso zokuphepha.

Ngaphezu kokulawula okunembile kwezinqubo, ukulinganisa ukugeleza kwe-ammonia kuyadingeka kuzo zonke izixhumanisi ukunciphisa izingozi ezibangelwa yi-NHx enobuthi, engabangela ukucasuka emehlweni, ekhaleni, emphinjeni ngamanani aphansi. Futhi kubangele ukuvuvukala okukhulu nokusha okuqhubekayo uma kuvezwa kakhulu. Ukuchayeka ku-ammonia egxilile kungaholela ebumpumputheni, ekuhlulekeni kokuphefumula ngisho nasekufeni.

I-Gas Ammonia vs. I-Liquid Ammonia

I-ammonia yegesi kanye neyoketshezi iyahlukahluka ngezakhiwo ezihlukile kanye nokusetshenziswa kwezimboni. Umehluko ophawulekayo phakathi kwezinhlobo ezimbili ze-ammonia uthinta kakhulu izixazululo zokuphatha, ukugcina kanye nokulinganisa. I-ammonia yegesi yakhiwa ama-athomu e-nitrogen nama-athomu e-hydrogen, abola emazingeni okushisa aphezulu ukuze akhe i-nitrogen ne-hydrogen. Ngaphezu kwalokho, i-ammonia yegesi iguqulwa ibe yi-nitric oxide ngosizo lwe-catalyst ngaphansi kwezimo ezifanele.

I-ammonia enobuthi ephefumulayo iyagqwala futhi isabela kakhulu kumswakama uma ihlangana namanzi kanye nolwelwesi lwamafinyila. I-ammonium hydroxide ekhiqizwayo iyingozi kakhulu futhi iyingozi ezicutshini.

I-ammonia ewuketshezi iwumphumela wokuncibilikisa igesi ye-ammonia emanzini, eyaziwa njengesixazululo se-ammonia esimanzi, okuwuhlobo loketshezi olungenambala oluguquguqukayo olunephunga elimnandi. Ukusabela okungenzeka kokushisa kufanele kuphathwe ngokucophelela lapho i-ammonia ihlangana namanzi. I-ammonia emanzi iyahwamuka uma ivezwa emoyeni, ibuyele esimweni segesi. Esinye isici ukuthi ingancibilikiswa kalula ibe yizinyibilikisi eziphilayo ezifana notshwala nama-ether.

Izidingo Zokulinganisa Nokulawula Ukugeleza

Njengoba kunezakhiwo zamakhemikhali ezigqwalisayo nezinye ezihlukile ze-ammonia yegesi, ukukwazi ukuhlukanisa kahle kubalulekile lapho ukhetha imitha yokugeleza efanele ngaphandle kokuphazamiseka kokunemba. Ukulethwa kwe-ammonia okuhle kudinga amamitha okugeleza ngokunemba okuphezulu. Futhi imfanelo yokumelana nokugqwala yemitha yokugeleza iyimfuneko ukuze imelane nezimo zemvelo ezinzima.

Izinto eziguquguqukayo zokusebenza ezifana nokushisa, ingcindezi kanye ne-viscosity kufanele zicatshangelwe ukuze kulinganiswe kahle futhi kunembile. Isinxephezelo sokushisa siwusizo ekugcineni ukufundwa okunembile kokuziphatha kwaso okushintshashintshayo nokushisa.

Izinselele Zokulinganiswa Kwegesi Ye-Ammonia

Sekukonke, kunezinselele ezahlukahlukene ekulinganisweni kwegesi kanye ne-ammonia ewuketshezi.

✤Ukuguquguquka okuphezulu kanye nokusabela kabusha

✤Impahla ebhubhisayo neyingozi

✤Incibilika ezinyibilikisini eziphilayo

✤Isinxephezelo sokushisa nokucindezela

I-Amonia Isetshenziswa Kanjani Ekukhiqizeni?

Ukusetshenziswa okuvelele kakhulu kwe-ammonia e-USA umthombo onamandla we-nitrogen wokukhula kwezitshalo. I-ammonia engaphezu kuka-80% isetshenziselwa ukukhiqiza umanyolo oqinile emkhakheni wezolimo. Lawo manyolo oqinile angasetshenziswa ngqo enhlabathini noma aguqulwe abe usawoti we-ammonium ohlukahlukene. Njengoba sonke sazi, ukwengezwa kwe-nitrogen kuba nomthelela ekukhuleni kokutshalwa kokudla okukhulu.

Sebenzisa kahle izakhiwo zamakhemikhali ezihlukile ze-ammonia ohlelweni lokupholisa lwezimboni. Ukushisa okukhulu kungamuncwa yi-ammonia yegesi ngesikhathi soketshezi, kufinyelelwe injongo yokugcina amazinga okushisa aphansi endaweni evalekile. Ngakho-ke lesi sici esingenhla sishiya i-ammonia ingenye yeziqandisi ezisebenza kahle kakhulu ekusetshenzisweni okungokoqobo.

Isibonelo, izimboni zokucubungula ukudla zidinga amafriji ezimboni ukulawula izinga lokushisa. Izimpahla ezibolayo zihlala zintsha futhi zisesimweni esihle ngokuhambisana nezindinganiso eziqinile zokuhlanzeka nokuphepha kokudla. Ikhethwa kakhulu phakathi kwezinye amafriji ngenxa yokusebenza kwayo kahle kokupholisa. Ngaphezu kwalokho, imiphumela yayo emincane emvelweni ilandela izitayela zamanje zokunciphisa ukukhishwa kwekhabhoni kanye nezindleko zamandla.

I-Amoniya iyinto eshintsha kakhulu ekunciphiseni ukukhishwa kwama-nitrogen oxide. Ngokuvamile, ifakwa ekuphenduleni nama-nitrogen oxide lapho izama ukuwaguqula abe yi-nitrogen yemvelo kanye namanzi kokubili ekunciphiseni okukhethayo (i-SCR) kanye nokunciphisa okukhethayo okungekhona okukhiphayo (i-SNCR). Ama-nitrogen oxide, anegalelo eliyinhloko ekungcolisweni komoya kanye nemvula ene-asidi, ayakwazi ukuguqulwa abe okuqukethwe okungenangozi ngemva kwe-SCR kanye ne-SNCR.

Kunembileukulinganisa ukugeleza kwe-ammoniaIkhula ibalulekile emigqeni yokuzenzakalela yezimboni kanye neyokucubungula ukuze kulondolozwe ukuthobela imithetho kanye nokusebenza kahle kokunciphisa i-NOx, lapho ukuphambuka okuncane kungathinta ukusebenza kohlelo kanye nemiphumela yemvelo.

Imitha Yokugeleza Kwe-Ammonia Enconyiwe

Thola okulungileimitha yokugeleza kwesisindo segesingeI-Lonnmeter. Uhla olubanzi lokusebenza okuphezulu kwezidingo ezahlukahlukene zesilinganiso sokugeleza kanye nokuhambisana negesi. Imitha yokugeleza kwesisindo inikeza ukufundwa okuthembekile nokunembile futhi ikusiza ukuthi ususe ukulinganisa okuphindaphindiwe ngesandla. Shiya opharetha kude nendawo enobuthi noma eyingozi, qinisekisa ukuphepha kwakho ngangokunokwenzeka.

Imitha Yokugeleza Kwe-Vortex engu-8800

Ayina-gasket futhi ayivaliimitha yokugeleza kwe-vortex yegesikuthuthukisa isikhathi sokusebenza kwenqubo futhi kunciphisa ukuphazamiseka okungalindelekile. Okuvelele kwayo kusekuklanyweni okusha kanye nenzwa ehlukanisiwe, okuvumela ukushintshwa kwezinzwa zokugeleza kanye nokushisa ngaphandle kokuphazamisa uphawu lwenqubo.
