Silicon Carbide FGD FGD FLAZULUMUTO YOPHUNZITSIRA MU BRORY

Flue Magesi Desalfurization (FGD) Openda Nozzles
Kuchotsa sulufur oxides, omwe nthawi zambiri amatchedwa Sox, kuchokera pampweya wotopetsa pogwiritsa ntchito reagents alkali, monga miyala yamtengo wapatali.

Zikagwiritsidwa ntchito posinthasintha njira kuti muthane ndi bolo, mikangano, kapena zida zina zomwe zingathe kumasula kotero kapena gawo la mpweya wamafuta. Sulufuyu osungirako maodidwewa amatenga mosavuta ndi zinthu zina kuti apange mafuta ovulaza ngati sulufuric acid ndipo amatha kusokoneza thanzi la anthu komanso chilengedwe. Chifukwa cha zotsatira za izi, kuwongolera pagawo ili mu mpweya wampweya ndi gawo lofunikira la magetsi owombera ndi mafakitale ena.

Chifukwa chakukoka, kudulana, ndi kudalira nkhawa, mchitidwe umodzi wodalirika kwambiri kuti uwongolere mpweya wa fungu (FGD) Kugwiritsa ntchito miyala yamiyala, madzi am'madzi, kapena njira ina yam'madzi. Zopukusira zopumira zimatha kusintha mosamala izi m'matambo. Popanga njira zowolokera mosadukiza, ma nozzles awa amatha kupanga malo omwe amafunikira kuti atengetse bwino pakuwongolera njira yosinthira mpweya.

Zovuta ndi laimu / miyala yamiyala

Monga taonera Chithunzi 1, FGD Systems Kugwiritsa ntchito laimu / miyala yamiyala yokakamiza makilotion (LSFO) kuphatikiza magawo atatu:

• Kukonzekera Kwakukulu, Kusamalira ndi Kusunga
• Chotchinga chotchinga
• Kutaya ndi Kugwira Bwino

Kukonzekera kwanyumba kumakhala koperekera miyala yophwanyika (CACO3) kuchokera ku malo osungirako utoto wa feanki. Zotsatira za mileete slorry imadumphiratse chotengera cholowera limodzi ndi mpweya wobowola mpweya ndi mpweya wabwino. Kupukutira zopweteka kumapereka magwero abwino ogwedeza omwe amayenda momasuka ndi mpweya wobwera. The2 mu mafuta a flue amagwira ndi calcium yolimba kwambiri kupanga calcium sulfite (Caso3) ndi CO2. Mphepo yomwe imayambitsidwa mu The atchler imalimbikitsa maxidation a calo3 mpaka casko4 (mawonekedwe a dihyhtete).

Zochita za LSFOR LSO ndi:

CCO3 + So2 → Goso3 + Co2h2o

Oxidid otumphukira amasonkhanitsa pansi pa yotumphukira ndipo pambuyo pake amabwezedwanso limodzi ndi kusinthika kwatsopano kumatulutsa mitu yophulika. Gawo la mtsinje wa recylecle limachotsedwa / dongosolo logwiritsira ntchito, lomwe limakhala ndi ma hydrocyclols, ng'oma kapena zosefera kapena zakumwa zowonongeka. Kudziteteza ku tank yogwirizira kumabwezerezedwanso ku thanki ya miyala yam'madzi kapena ku hydrocyclone komwe kumasefukira kumachotsedwa ngati.

Mayime / Limeest adakakamiza oxidatin chonyowa kusintha njira

Njira zonyowa lsfo zimatha kukwanitsa kuchotsedwa kwa S2-97 peresenti. Kufikira pamlingo wopitilira 97,5 peresenti kuti akwaniritse zofunikira zowongolera, komabe, ndizovuta, makamaka chifukwa cha mbewu pogwiritsa ntchito makala a Sulfur Wam'mwamba. Magnesium amatha kuwonjezeredwa kapena mwalawo umatha kuwerengetsa ndalama zambiri (CAO), koma kusintha koteroko kumaphatikizapo zida zobzala zobzala zobzala komanso ndalama zogwirira ntchito komanso ndalama zophera. Mwachitsanzo, kuwerengera kwa laimu kumafuna kukhazikitsa kwa laimu yaime. Komanso laimu imadzitukumula kwambiri ndipo izi zimawonjezera mphamvu ya mapangidwe a scrubber mu scrubber.

Mtengo wa kuwerengedwa ndi mphaka wa laimu ukhoza kuchepetsedwa ndi jekeseni mwachindunji mu ng'anjo ya boilet. Munjira imeneyi, lizi yomwe yatulutsidwa mu boiler imatengedwa ndi mpweya wowoneka bwino mu scrubber. Mavuto olimbitsa thupi amaphatikizanso kuwongolera kwa boiler, kulowerera ndi kusamutsa kutentha, ndi laimu kuphatikizika chifukwa chodzaza ndi bouler. Komanso, laimu limachepetsa kutentha kotentha kwa phulusa loyera m'miyala, yopangidwa ndi zolimba zomwe sizichitika.

Zinyalala zamadzimadzi kuchokera ku njira ya LSFO zimayendetsedwa m'madziwe omwe amakhazikika limodzi ndi zinyalala zamadzi kuchokera kwina kulikonse mu chomera chamagetsi. Kunyowa kwamadzimadzi onyowa kungakhuta ndi sulfate ndi sulfate mankhwala ndi masinthidwe ake amasulidwa ku mitsinje, mitsinje kapena zina zamadzi. Komanso, kubwezeretsanso madzi otakamwa Mtunduwu umatha kukula pang'onopang'ono pokhapokha magazi okwanira amaperekedwa kuti asunge kutentha kwa mchere pansi. Vuto lowonjezereka ndikusachedwa kutentha kwa zinyalala, zomwe zimabweretsa zofunika kwambiri m'madziwe akuluakulu, okhazikika kwambiri. M'mayiko ena, malo otsekera mudziwe okhazikika amatha kukhala ndi 50 peresenti ya gawo lazomwe limatha miyezi ingapo pambuyo posungira.

Katswiri wa calcium sulfate yochiritsidwa kuchokera ku zokongoletsera zobwezeretsedwanso zimatha kukhala zazitali kwambiri ndi phulusa la sulfam sulfite. Izi zimalepheretsa calcium sulfate yogulitsidwa ngati gypsim gypsum kuti mugwiritse ntchito pakhoma, pulasitala, ndi simenti. Mwala wosasunthika umakhala wokhazikika wopezeka mu gypsum gypsum ndipo ndi kudetsa kwachilengedwe (minid) gypsum. Pomwe miyala yamiyala yokha siyingasokoneze katundu wa pallboard imatha, malo ake a Abrasive omwe amapezeka pangozi ya zida zopangira. Calcium sulfite ndi chidetso chosayenera mu gypsum iliyonse monga tinthu tating'onoting'ono tating'ono timakhala ndi mavuto okamba ndi mavuto ena monga kusamba kwa keke ndikumathira madzi.

Ngati zolimba zopangidwa munjira ya LSSO sizogulitsana ndi mankhwala a gypsum, izi zimabweretsa vuto lotayidwa. Kwa 1000 mw boiler 1 peresenti ya sulfur sulfur malasha, kuchuluka kwa gypsum kuli pafupifupi matani 550 / tsiku. Kwa chomera chomwecho chikuwombera 2 peresenti ya sulufule la sulfur, kupanga gypsum kumawonjezera pafupifupi 1100 matani / tsiku. Kuphatikiza 1000 matani / tsiku la ntchentche phula, izi zimabweretsa matani okwanira pafupifupi 1550 matani a sulfur telfur kapena matani 2100% ya sulfare ya 2% ya sulfar.

Ubwino wa EadS

Njira yotsimikiziridwa ku LSMO Kutulutsa miyala yamiyala yokhala ndi ammonia ngati okonzanso kuchotsedwa. Migonje yolimba yokonza, yosungirako, yoyendetsa ndi mayendedwe munthawi ya LSFO imasinthidwa ndi akasinja osavuta osungirako amchere kapena ma ammonia. Chithunzi 2 chikuwonetsa kusachita bwino kwa EDS System yomwe yaperekedwa ndi Jet Inc.

Amonia, mpweya wa mafuta, mpweya wa oxidizing mpweya ndi njira zamagetsi zimalowa cholembera chokhala ndi zigawo zingapo zopukusira. Ma nozzles amapanga magwero abwino a ammonia kuti atsimikizire kuti akukumana ndi zowongolera ndi mpweya wobwera molingana ndi zotsatirazi:

(1) So2 + 2nh3 + H2O → (NH4) 2SO)

(2) (nh4) 2SOh3 + →o2 → (nh4) 2SO

The Sox mu Stom Gaumu yamagesi yamagesi imakhudzana ndi ammonia kumtunda kwa chotengera kuti itulutse Ammonium sulfite. Pansipa kwa chotengeracho chimakhala ndi thanki ya oxidide pomwe mpweya umakhala ndi ammonium sulfite ku ammonium sulfate. Zotsatira za Amonium sulfate zimaponyedwa kumbuyo kwa mitu yopanda mizu m'malo angapo pakuyamwa. Asanafike pamtunda wa mafuta otsegulira, imadutsa muzowunikira zomwe zimachulukitsa madontho omwe ali ndi madzi opatsa mphamvu ndipo amagwira bwino ntchito.

Amoni omwe ali ndi ma ammonia ndi oxidation a sulfite kuti sulfate akwaniritse kuchuluka kwamphamvu kwambiri. Mapaumu anayi a sulmoum sulfate amapangidwa pamtunda uliwonse wa ammonia kudya.

Monga njira ya LSO, gawo la mtsinje wa rencle / malonda limatha kuperekedwa kuti atulutse malonda. M'dongosolo la EADS, yankho lazomera limaponyedwa ku dongosolo lozizira lokhala ndi hydrocyclone ndi centrifuge kuti mumveketse mankhwala a ammonium sulm isanayike ndikuyika. Zakumwa zonse (hydrocyclone kusefukira ndi centrifuge centrate) amabwerera ku tambala yocheperako ndipo kenako adadziwitsidwanso mu kuyamwa kwa Amonium Sulfate Kubwereza.

• Makina owoneka bwino amapereka mofatsa (> 99%), yomwe imapatsa mbewu zoyendetsedwa bwino za malasha mochuluka kuti ziziphatikiza zotsika mtengo, makala a sulufule.
• Pomwe masfo amapanga matani 0,7 a CO2 pa co2 ya tani iliyonse ya so2 yachotsedwa, ma eadis amatulutsa co2.
• Chifukwa laimu ndi miyala imayankhidwa poyerekeza ndi Amonia ya Kuchotsa kotero, njira zapamwamba zimagwiritsidwa ntchito madzi ndi kupopa mphamvu zimafunikira kuti tikwaniritse mitengo yayitali. Izi zimabweretsa ndalama zambiri zogwirira ntchito za LSFO.
• Mtengo waukulu wa ma eds ndi wofanana ndi omwe apanga dongosolo la LSFO. Monga taonera pamwambapa, pomwe dongosolo la ziwonetserozi limafunikira masinthidwe a ammonium and progedamect ndi zida za madzeretsa, malo okonzanso zokonzanso ndi LSFO siyofunikira kwa mitsuko, kugwira ndi kunyamula.

Ubwino wapadera kwambiri wa ma eds ndiye kuchotsedwa kwa madzi ndi mafomu olimba. Tekinoloji ya EADS ndi njira yotulutsa madzi zero, yomwe siyikutanthauza kuti palibe chithandizo chamadzi chomwe chimafunikira. The Amoni wolimba Sulproduct imatha kumera mosavuta; Amoni sulpate ndi feteleza wogwirizanitsa kwambiri ndi feteleza mdziko lapansi, ndipo kukula kwa msika padziko lonse lapansi kumayembekezeredwa kwa 2030 Kutengera ndi mikhalidwe yazachuma ndi msika ammonium sultelitege amatha kuthetsa ndalama zosungunuka mpweya wa mafuta a ammonia ndikupeza phindu lalikulu.
