Okokuqala, i-centrifugal air compressor imfucuza yokubuyiselwa kokushisa kanye nesizinda sobuchwepheshe bokusetshenziswa esidingweni samandla somhlaba siyaqhubeka nokukhula kanye nokuhlinzekwa kwangempela kwesimo esibucayi esinciphayo, ukonga amandla kanye nokunciphisa ukukhishwa kwekhabhoni kubalulekile.Amafekthri nawo abelokhu efuna indawo engaba khona yokonga amandla, futhi amasistimu omoya oCompressed aphethe amandla okonga okukhulu kwamandla.I-Centrifugal Compressed air ingenye yemithombo yamandla esetshenziswa kakhulu embonini.I-Centrifugal Air compressor iyi-speed compressor ngenxa yesakhiwo sazo esihlangene, isisindo esincane, ububanzi obubanzi bomthamo wokuqeda, nenani elincane lezingxenye ezintekenteke, imodeli yensiza inezinzuzo zokusebenza okuthembekile, impilo ende yesevisi, ukungangcoliswa kwegesi yokukhipha ngokugcoba. uwoyela, izinga eliphezulu lokuhlinzekwa kwegesi, umsebenzi ozinzile nothembekile, futhi ulungele amabhizinisi asebenzisa igesi enkulu kanye nekhwalithi ephezulu yegesi, isibonelo, imithi, i-electronics, insimbi namanye amabhizinisi amakhulu, ukukhethwa okujwayelekile kwe-centrifugal air compressor kusetshenziswa kabanzi. emikhakheni yezimboni yesimanje.
Izithombe ezereferensi kuphela
Kudinga amandla amaningi ukuze uthole umoya omuhle Ocindezelwe.Ezinkampanini eziningi ezikhiqizayo, i-Compressed Air ibala u-20% kuya ku-55% wesamba esisetshenziswa ugesi.Ukuhlaziywa kokutshalwa kwezimali ohlelweni lwe-Compressed air lweminyaka emihlanu lubonisa ukuthi ugesi ubala u-77% wezindleko eziphelele, ne-85% yokusetshenziswa kwamandla eguqulwa ibe ukushisa (ukushisa kokucindezela) .Ukuvumela lokhu kushisa “Okweqile” ukuthi kuphumele emoyeni kuthinta indawo ezungezile futhi kudala “Ukushisa” ukungcola.Kwamabhizinisi, uma sifuna ukuxazulula inkinga yamanzi ashisayo asekhaya, njengokugeza abasebenzi, ukufudumeza, noma amanzi ashisayo embonini, njengokuhlanza nokomisa izintambo zokukhiqiza, udinga ukuthenga amandla, ugesi, amalahle, isitimu segesi yemvelo, njalo njalo.Le mithombo yamandla ayidingi nje kuphela inani elikhulu lokutshalwa kwezimali, kodwa futhi ibangela ukukhishwa kwe-carbon dioxide, ngakho ukunciphisa ukusetshenziswa kwamandla nokushisa kabusha kusho izindleko zokusebenza eziphansi!
Inombolo enkulu yomthombo wokushisa we-centrifugal air compressor ovela ekusetshenzisweni kwamandla kagesi, isetshenziswa kakhulu ngalezi zindlela ezilandelayo: 1)38% kagesi oguqulelwe ekubeni amandla okushisa agcinwa endaweni epholile yesigaba sokuqala Umoya ocindezelwe futhi uthathwe ukupholisa. amanzi, 2)28% kagesi oguqulelwe ekubeni amandla okushisa agcinwa esigabeni sesibili esipholile Umoya ocindezelwe futhi uthathwe amanzi apholisayo, 3)28% kagesi oguqulelwe ekubeni amandla okushisa ugcinwa esigabeni sesithathu esipholile Umoya ocindezelwe futhi kuthathwe amanzi apholisayo, futhi u-4)6% kagesi oguqulelwe amandla okushisa ugcinwa emafutheni okugcoba futhi uthathwe ngamanzi apholisayo.
Njengoba kubonakala kulokhu okungenhla, i-compressor ye-centrifugal, eguqulwa ibe amandla okushisa, okungaba ngu-94% wayo angabuyiselwa.Ithuluzi lokubuyisela amandla okushisa liwukubuyisela iningi lamandla okushisa angenhla ngendlela yamanzi ashisayo ngaphandle komphumela ongemuhle ekusebenzeni kwe-compressor.Izinga lokubuyiselwa kwesigaba sesithathu lingafinyelela ku-28% wamandla we-shaft wokufaka wangempela, izinga lokubuyisela lesigaba sokuqala nesesibili lingafinyelela ku-60-70% wamandla we-shaft wokufaka wangempela, kanye nenani eliphelele lokubuyisela lesigaba sesithathu finyelela ku-80% wamandla we-shaft wangempela wokufaka.Ngokushintshwa kwe-compressor, kungaba ngesimo sokugaywa kabusha kwamanzi ashisayo kumabhizinisi ukuze konge amandla amaningi.Njengamanje, abasebenzisi abaningi ngokwengeziwe emakethe baqala ukunaka ukuguqulwa kwama-centrifuges.I-Centrifugal compressor heat recovery kumele ilandele izimiso: 1. Qinisekisa ukuphepha nokuzinza komshini.2. Qinisekisa ukuphepha kanye nokuzinza kokuphakelwa kwamanzi.3. Inqubo yokubuyisela amandla ukuze kuzuzwe ukuncishiswa kokusetshenziswa kwamandla kwesistimu okuphelele, okungase futhi kuthuthukise ukusetshenziswa kwamandla emishini;4. Okokugcina, ekushiseni okutholiwe, okuphakathi kuyashiswa kuze kufike ezingeni lokushisa eliphezulu kakhulu ukuze kwandiswe ububanzi bokufaka isicelo.Okwesibili, i-centrifugal air compressor waste heat recovery and use of real case analysis
Inkampani enkulu eyenza imithi esifundazweni saseHubei, isibonelo, ibisebenzisa ukufudumeza kukagesi ukuze ihlangabezane nezidingo zokushisa kwamanzi angcolile ohlelweni lokukhiqiza.Ubuchwepheshe be-Ruiqi bokuguqulwa kwayo kokuqala kwe-compressor ye-centrifugal, ukusebenza kwensimu ye-1250 kw, i-2 kg ye-pressure centrifugal compressor, izinga lokulayisha lika-100%, isikhathi sokugijima amahora angu-24, lokhu ukushisa okuphezulu Umoya ocindezelwe.Umqondo wokuklama uwukuqondisa izinga lokushisa eliphezulu Umoya ocindezelwe kuyunithi yokutakula ukushisa, ubuyele endaweni epholile ngemva kokuqedwa ukushintshanisa ukushisa, futhi ufake i-automatic proportional integral valve endaweni ezungezayo yamanzi epholile ukuze ulawule ukugeleza kwamanzi. , qinisekisa ukuthi izinga lokushisa lokuphuma kwamanzi liku-50 ° C, futhi ufake ama-valve e-by-pass ukuze uqinisekise ukuthi izinga lokushisa eliphezulu Umoya ocindezelwe ungena endaweni epholile uwoyela osuka ku-by-pass ngesikhathi sokugcinwa nokulungiswa kweyunithi yokubuyisela ukushisa kwemfucuza ukuze kuqinisekiswe ukuzinza. ukusebenza kohlelo.Umthelela wesistimu yokubuyisela ukushisa kwemfucuza uthathwa embhoshongweni wokupholisa esizeni, futhi amanzi angama-30-45 ° C ayindawo yokushintshanisa ukushisa, kuvimbela ikhwalithi yamanzi ukuba iqine kakhulu, ukungcola futhi kuholele ekutholeni ukushisa okweqile kweyunithi ukugqwala, ukukala, ukuvimbela kanye nezinye izenzakalo, ukwandisa izindleko zokugcinwa kwebhizinisi.Uhlelo lwamanzi lweyunithi yokubuyisela ukushisa kwemfucuza luzonikwa amandla ngokwengezwa kwephampu yokujikeleza ngamapayipi ukuze kuthathwe amanzi embhoshongweni wokupholisa futhi awahambise endaweni yokubuyisela ukushisa kwemfucuza ukuze ashise kumazinga okushisa amisiwe ngaphambi kokungena echibini lokushisisa indle.
Idizayini yesikimu isekelwe kumingcele yesimo sezulu senyanga eshisa kakhulu ehlobo, okungaba ngu-20G/kg.Ebusika, lapho isimo sokusebenza sigcwele, uhlelo lusebenza ngokuvumelana nesikhathi sokushisa esinikezwa ikhasimende, futhi izinga lokushisa eliphansi kakhulu liyi-126 degrees, futhi izinga lokushisa liyancipha libe ngaphansi kwama-degrees angu-50, ngalesi sikhathi umthwalo wokushisa. icishe ibe ngu-479 kw, ngokwezinga eliphansi lama-degree angama-30 okuthathwa kwamanzi, lingakhiqiza ama-degree angama-80 amanzi okukhipha usawoti emanzini angaba ngu-8460 kg/h.Uma kuqhathaniswa nezimo zokusebenza zasehlobo, izimo zokusebenza zasebusika zidinga indawo yokudlulisa ukushisa eqinile.Isibalo esingezansi sibonisa izimo zokusebenza zangempela ngoJanuwari ebusika, lapho izinga lokushisa lomoya lokungena liyi-129 ° C, izinga lokushisa lomoya lokuphuma liyi-57.1 ° C, futhi izinga lokushisa lamanzi okungena liyi-25 ° C, lapho izinga lokushisa lamanzi ashisayo lisuka ngqo. indawo yokushisa iklanyelwe ukuthi ibe ngu-80 ° C, ukuphuma kwamanzi ashisayo ngehora ngu-8.61 m3.Amahora angu-24 ukuhlinzeka ngamanzi ashisayo ebhizinisi mayelana ne-207 M3.
Uma kuqhathaniswa nemodi yokusebenza yasehlobo, imodi yokusebenza yasebusika inzima kakhulu.Ezimweni zokusebenza zasebusika, isibonelo, izinsuku ezingama-330 ngonyaka ukuze inkampani inikeze amanzi ashisayo 68310m3.1 M3 amanzi ukusuka ku-25 ° C izinga lokushisa likhuphuka 80 ° C ukushisa: Q = cm (T2-T1) = 1 kcal/kg/° C × 1000 kg × (80 ° C-25 ° C-RRB- = 55KCALkcal ingawonga amandla okwebhizinisi: 68M30 m3 * 55000 kcal = 375705000 kcal
Le phrojekthi yonga amandla angaba ngu-357,505,000 kcal njalo ngonyaka, okulingana namathani angu-7,636 we-steam ngonyaka;529,197 cubic metres wegesi yemvelo;459,8592 kwh kagesi;amathani ayi-1,192 amalahle ajwayelekile;kanye namathani angaba ngu-3,098 okukhishwa kwe-CO2 ngonyaka.Unyaka ngamunye ukuze inkampani yonge izindleko zokushisisa ugesi ezingaba yizigidi ezi-3 zamayuan.Lokhu kukhombisa ukuthi ukwenza ngcono okonga ugesi akukwazi nje kuphela ukudambisa ingcindezi ekunikezeni amandla nokwakhiwa kukahulumeni, kunciphise ukungcoliswa kwegesi engcolile futhi kuvikele imvelo, kodwa okubaluleke kakhulu, ukuvumela amabhizinisi ukuba anciphise ukusetshenziswa kwamandla futhi anciphise izindleko zawo zokusebenza.
