Amamitha wokuminyana okungaphakathi komugqa awushintshi wegeyimu wokuphika ezitshalweni zamandla phakathi nezinqubo zezimboni. Lawa mageji ahlakaniphile asungula avumela opharetha ukuthi baqaphe ukuminyana ngesikhathi sangempela, kanye namadivayisi abalulekile abhekana nezinqubo zamakhemikhali eziyinkimbinkimbi. Kubalulekile ukuthi ama-opharetha abhekane nezinselele zokusebenza njengokugcina imithetho eqinile yezemvelo. Bheka izimo ezinemininingwane abasebenza kuzo ukuze baxazulule izinkinga zezimboni eziyinkimbinkimbi futhi baqede umsebenzi onzima kodwa ophindaphindwayo.
Izinkinga Zezobuchwepheshe Ezikhohlisayo Ekuchazeni
Ukulungiswa kokukhishwa kwe-nitrogen oxide (NOx) akuwona umsebenzi olula. I-nitrogen oxide ayikwazanga ukuqedwa ngokuphelele, kungakhathaliseki ukuthi ezitshalweni ezibaswa ngamalahle, ezishiswe uwoyela noma ngisho nezitshalo eziphehla uphethiloli. Ukulawulwa kokukhipha intuthu ngokunemba kuhlobene nokuNciphiswa kwe-Selective Catalytic (SCR) noma i-Selective Non-Catalytic Reduction (SNCR), lapho ama-reagents engezwa emfudlaneni wegesi ewuketshezi ukuze kuqhutshekwe nokusabela. Noma kunjalo, ukuqapha umthamo onembile ngesikhathi sangempela kubhekana nezinselele eziningi ezivela ezimeni zokusebenza eziyinkimbinkimbi. Ukunemba esilinganisweni kungase kubangele ukushelela kwe-ammonia kanye nemfucumfucu yama-reagents.
I-Lonnmeter idizayina futhi ikhiqize imitha yokuminyana emgqeniukukala ukugxilisa ingqondo okuqhubekayo ukugwema amaphutha abantu kumasampula okuvamile. Amasampula omuntu ancike kakhulu ekuhlolweni ngezikhathi ezithile nasekulinganiseni okungaqondile. Okunjaloimitha yokuminyana ku-inthanethiiyakwazi ukubona ukuguquguquka okuncane kokuqapha ukuminyana ukusiza ukulungisa okunembayo, igcine zonke izinqubo zokuphika zizinzile futhi zisebenza kahle.
Ngaphezu kwalokho, iphinde isebenze ekunikezeni amapharamitha akhombisa ikhwalithi yokuxuba, ukungaguquguquki kwe-reagent kanye nezinga lokugeleza. Isibonelo, ukungahambisani kokugeleza kwe-urea ekuncibilikeni emanzini kuphazamisa i-chemistry yokusabela. Ngokuqapha udaka ngokuqondile epayipini, amamitha okuminyana emgqeni aqinisekisa ukuthi ukugxila okufunayo kugcinwa kusukela ekugcinweni kuya kumjovo, kunciphisa ubungozi bokungasebenzi kahle kwenqubo noma ukungalandelwa kwemvelo.
Amamitha Okuminyana Kwezimboni anconyiwe
Ukuthuthukisa I-Automation ekuchazeni nasekuthembekeni kwesistimu
Sezadlula izinsuku lapho abaqhubi bezitshalo kwadingeka bathembele ekungeneleleni okwenziwa ngesandla ukuze balungise kahle umjovo we-reagent. Amamitha okuminyana esimanjemanje ahlanganisa ngaphandle komthungo kuma-Distributed Control Systems (DCS) noma ama-Programmable Logic Controllers (PLC), okuvumela iluphu yempendulo ezenzakalelayo ngokugcwele. Lapho ukufundwa kokuminyana kuchezuka kububanzi obusethiwe, isistimu ilungisa ngokuzenzakalelayo izinga lokugeleza kwe-reagent noma ihlanza isixazululo njengoba kudingeka. Lokhu kuzenzakalela akunciphisi umthwalo kubasebenzisi kuphela kodwa futhi kuqeda ukubambezeleka okuhlobene nokuthatha izinqumo komuntu.
Kubalulekile ukulinganisa ukugeleza kwamakhemikhali ekuhlanganiseni i-desulfurization kanye nokucubungula i-denitration, lapho i-lime slurry nezixazululo ze-ammonia zisetshenziswa ngesikhathi esisodwa. Ukuqapha ukuminyana kwalolo ketshezi olubili luyimfuneko yokusebenza okuvamile kwe-desulfurization kanye ne-denitration. Leli zinga lokuxhumanisa lisiza ukuvimbela izinkinga ezivamile njengokucwiliswa kwenhlabathi kumapayipi e-limestone noma ukweqisa kwe-ammonia, kokubili okungase kubangele ukuvalwa okumba eqolo noma ukulungiswa.
Ngaphandle kwalokho, amamitha anjalo aqinile we-inline density amelana nezimo ezinzima esitshalweni sikagesi. Ukuze amadizayini akhethekile amelane namazinga okushisa aphezulu nezingcindezi, alungele ukuphatha amakhemikhali alimazayo ezimeni eziyinselele ezifana nesistimu yokukhipha igesi ephuma ku-flue.
Ukufakwa kwezicelo zama-Inline Density Meter Esikhungweni Samandla Esibaswa Ngamalahle
Ngokuvamile, izimboni zamandla aphehlwa ngamalahle zihlupha ngokungasebenzi kahle ekukaleni ukuminyana kanye nezinkinga zobuchwepheshe ezihlobene ochungechungeni, okuhlanganisa kodwa kungagcini nje ngokuvaleka kwamapayipi, isiliphu se-ammonia kanye nokulungiswa okungenzeka. Imitha yokuminyana emgqeni wemfologo iyithuluzi elihlakaniphile elifanelekile kukho kokubili ulayini womjovo we-ammonia kanye nesistimu ye-limestone slurry.
Imiphumela yaba inguquko. Ukuqapha ukuminyana kwesikhathi sangempela kuvumele isitshalo ukuthi silungise kahle umthamo we-reagent ngokunemba okungakaze kubonwe ngaphambili. Amazinga okushelela kwe-ammonia ehle ngaphezu kuka-90%, kanti ukusebenza kahle kokunciphisa i-NOx kudlule ama-92%. I-limestone slurry, ebidale ukukala nokuvinjwa ngaphambilini, yagcinwa isezingeni elifanele, isusa ukulungiswa okungahleliwe futhi yehlisa isikhathi sokuphumula ngama-20%. Lokhu kuthuthukiswa akwenzanga nje kuphela ukuthi imboni ihambisane nezindinganiso zemvelo kodwa futhi yehlise izindleko zokusebenza ngo-15%.
Kungani I-Inline Density Meters Idingeka
Okwenza amamitha we-inline density ahluke kwezinye izixazululo zokuqapha ukuguquguquka kwawo kanye nokuvumelana nezimo. Abagcini ngokuchaza incazelo; izicelo zabo zidlulela kunoma iyiphi inqubo yezimboni edinga ukuphathwa okunembayo koketshezi. Ngomongo wezimboni zamandla, lokhu kufaka phakathi amasistimu okukhipha i-sulfurization, ukuhlanzwa kwamanzi angcolile, nemisebenzi yokuhlanganisa uphethiloli. Ikhono labo lokuhlinzeka ngedatha yesikhathi sangempela, enembile, nengasetshenzwa ibenza babe yitshe lesisekelo lokuthuthukiswa kwenqubo yesimanje.
Ngokusebenzisa lezi zisetshenziswa, izimboni zamandla zingafinyelela izinga lokulawula inqubo ebingafinyelelwa ngaphambilini. Izinzuzo zidlulela ngale kokuthobela kanye nokusebenza kahle; zifaka phakathi impilo ende yemishini ethuthukisiwe, izindleko zokulungisa ezincishisiwe, nokusimama okuthuthukisiwe. Kubasebenzi abakwazisa kokubili ukusebenza kanye nesibopho sendawo ezungezile, amamitha okuminyana emgqeni awawona nje utshalomali—ayisidingo.
Isiphetho
Ukwamukelwa kwamamitha we-inline density systems kuma-denitration systems kuyisibonelo sokuthi ubuchwepheshe obuthuthukisiwe bungaguqula kanjani izinqubo zezimboni. Ngokubhekana nezinselele ezifana nokungaguquguquki kwe-reagent, ukushelela kwe-ammonia, kanye nokucubungula okuzenzakalelayo, lezi zisetshenziswa zivumela izitshalo zikagesi ukuthi zisebenze kahle kakhulu, ngokuqhubekayo, nangenzuzo. Irekhodi labo elifakazelwe ezinhlelweni zokusebenza zomhlaba wangempela ligcizelela ukubaluleka kwabo njengethuluzi elibalulekile ekulweni nokukhishwa kwe-NOx. Uma ubheke ukuphakamisa imisebenzi yakho yokuphika, asikho isikhathi esingcono sokuhlola amandla okukala kokuminyana okusemgqeni.
