Sezvo zvidyarwa zvitsva zvemagetsi emarasha zvinouya pamhepo kuti zvizadzise kudiwa kuri kukura kwemagetsi muUnited States nepasirese, pane kuwedzera kuri kuda kwekuchenesa zvinobuda muzvirimwa kuti zvisangane nemirairo yemhepo yakachena. Mapombi akakosha uye mavharuvhu anobatsira kunyatso shandisa aya mascrubber uye kubata abrasive slurry inoshandiswa mu flue gas desulfurization (>FGD) process.

Nekufambira mberi kweruzivo rwemichina mukugadzira manyuko emagetsi matsva mukati mezana ramakore rapfuura, chinhu chimwe chisati chachinja zvakanyanya kuvimba kwedu nemafuta emafuta, kunyanya marasha, kugadzira magetsi. Inopfuura hafu yemagetsi muUnited States inobva mumarasha. Imwe yemigumisiro yekupisa marasha mumagetsi emagetsi ndiko kusunungurwa kwesulfure dioxide (SO 2) gasi.

Nezvemapombi emagetsi matsva anosvika 140 ari mupombi muUnited States moga, kutyira kusangana nemirairo yemhepo yakachena pano nepasirese kuri kutungamira nzira yezvivakwa zvemagetsi zvitsva uye zviripo - zvakashongedzerwa nehutsi hwepamusoro "hwekukwesha". SO2 yave kubviswa kubva muflue gasi nenzira dzakasiyana dzinowanzozivikanwa se flue gas desulfurization (FGD). Sekureva kweEnergy Information Administration, iyo inopa huwandu hwesimba kuhurumende yeUS, zvishandiso zvinotarisirwa kuwedzera zvivakwa zvavo zveFGD kusvika 141 gigawatts yekukwanisa kutevedzera danho rehurumende kana remubatanidzwa.

FGD masisitimu anogona kushandisa yakaoma kana kunyorova maitiro. Iyo yakanyanya kunyorova yeFGD maitiro anoshandisa scrubbing solution (kazhinji limestone slurry) kutora SO2 kubva kune off-gasi rukova. Iyo yekunyorova yeFGD maitiro ichabvisa pamusoro pe90% yeSO2 mune flue gasi uye tunhu tunhu. Muchidimbu chemakemikari maitiro, limestone mu slurry inoshandurwa kuva calcium sulfite apo limestone slurry inopindirana ne flue gasi mumudziyo. Muzvikamu zvakawanda zveFGD, mhepo inopeperetswa muchikamu chemucherechedzo uye inoita kuti calcium sulfite iite calcium sulfate, iyo inogona kupepetwa zviri nyore nekudirwa mvura kuti igadzire chinhu chinoomesa, chakagadzikana chinogona kuraswa mumarara kana kutengeswa se chigadzirwa chekugadzira simende, gypsum wallboard kana sekuwedzera fetiraiza.

Pombi sarudzo yeFGD

Nekuti iyi limestone slurry inoda kufamba zvakanaka kuburikidza neyakaoma maindasitiri maitiro, kusarudza mapombi akakodzera nemavharuvhu - neziso rakanangana nemutengo wavo wehupenyu hwese uye kugadzirisa - kwakakosha.

Maitiro eFGD anotanga apo chikafu cheraimu (dombo) chinodzikiswa muhukuru nekuchipwanya muguyo rebhora rozosanganiswa nemvura mutangi rekupa slurry. Iyo slurry (inenge 90% yemvura) inozopombwa mutangi rekunyura. Sezvo kuwirirana kweimestone slurry kunowanzochinja, kusveta mamiriro ezvinhu anogona kuitika, izvo zvinogona kutungamirira ku cavitation uye kukundikana kwepombi.

Yakajairika pombi mhinduro yeichi application kuisa carbide slurry pombi kuti imirire aya marudzi emamiriro. Cemented metal pombi dzinoda kugadzirwa kuti dzimire zvakanyanya abrasive abrasive slurry sevhisi uye dzakagadzirirwawo kuve nyore kuchengetedza nekuchengetedza. Yakakosha kuinjiniya yepombi inorema-basa rinotakura mafuremu uye shafts, yakawedzera-yakakora madziro zvikamu uye zviri nyore kuchinjika zvipfeko zvinopfeka. Hupenyu hwese hwekutenderera mutengo kutariswa kwakakosha pakutsanangura mapombi emamiriro ekushanda akaomarara senge FGD sevhisi. Yakakwira chromium alloy pombi yakanakira nekuda kwekuora pH kweiyo slurry.

Iyo slurry inofanirwa kupomba kubva kuabsorbier tank kusvika kumusoro kweshongwe yekupfapfaidza, uko inopfapfaidzwa ichidzika semhute yakanaka inopindirana neinokwira-inofambisa flue gasi. Sezvo mavhoriyamu ekupomba anowanzo kubva pa16,000 kusvika 20,000 magaloni e slurry paminiti nemisoro iri pakati pe65 ne110 tsoka, rubber-lined>slurry pombi ndiyo yakanyanya kupomba mhinduro. Zvekare, kusangana nehupenyu-kutenderera kutariswa kwemitengo, pombi dzinofanirwa kunge dzakashongedzerwa nehombe-dhayamita impeller yekuderera kumhanya kwekushanda uye hupenyu hurefu hwekupfeka, uye nemunda-inotsiviwa nerabha liner kuitira kugadzirisa nekukurumidza. Muchigadzirwa chemagetsi chinobatidzwa nemarasha, mapombi maviri kusvika mashanu achashandiswa mushongwe yega yega yekupfapfaidza.

Sezvo slurry inounganidzwa pasi peshongwe, mamwe mapombi ane rubber-lined anodiwa kutakura slurry kumatangi ekuchengetera, madhamu ekumisa, nzvimbo dzekurapa tsvina kana mafirita. Zvichienderana nerudzi rweFGD process, mamwe mapombi epombi anowanikwa kune slurry discharge, pre-scrubber recovery uye mafuta sump application.
