Mvura yeMarasha
I. Hunhu hwemuviri uye Mabasa
Dombo remvura yemarasha idombo rakagadzirwa nemarasha, mvura uye zvimwe zvinhu zvishoma zvemakemikari. Zvichienderana nechinangwa, dombo remvura yemarasha rakakamurwa kuita mafuta emarasha nemvura yemarasha ane huwandu hwakawanda uye dombo remvura yemarasha rekugadzira gasification muchoto cheTexaco. Dombo remvura yemarasha rinogona kupombwa, kupiswa, kuchengetwa uye kupiswa uye kupiswa munzvimbo yakagadzikana. Matani maviri edombo remvura yemarasha anogona kutsiva tani imwe yemafuta emafuta.
Dongo remvura yemarasha rinopisa rinoshanda zvakanaka kupfuura mamwe ese, kuchengetedza simba uye mabhenefiti ezvakatipoteredza, chimwe chezvinhu zvakakosha zvetekinoroji yemarasha akachena. Dongo remvura yemarasha rinogona kutakurwa nekufamba kwenguva refu nekufambisa mapaipi nekudyara mari shoma uye mari shoma yekushandisa. Rinogona kupiswa zvakananga pasina kupera mvura mushure mekusvika pachiteshi, uye nzira yekuchengetedza nekutakura inenge yavharwa zvizere.
Mvura inokonzera kurasikirwa nekupisa uye haigone kuburitsa kupisa panguva yekutsva. Saka, huwandu hwemarasha hunofanira kusvika padanho repamusoro -- 65 ~ 70% kazhinji. Kuwedzerwa kwemakemikari kunenge 1%. Kurasikirwa nekupisa kunokonzerwa nemvura kunoumba inenge 4% yehuwandu hwemacalorie emvura yemarasha. Mvura chinhu chisina kugadzika chinoitwa mukugadzira gasification. Kubva pamaonero aya, huwandu hwemarasha hunogona kudzikiswa kusvika 62% ~ 65%, izvo zvinogona kukonzera kuwedzera kwekupisa kweokisijeni.
Kuti zvive nyore kupiswa uye kugasirwa kwegesi, slurry yemvura yemarasha ine zvinodiwa kuti marasha anyatsonaka. Muganho wepamusoro wehukuru hwezvimedu zveslurry yemvura yemarasha yemafuta (hukuru hwezvimedu hune mwero wekupfuura weasingasviki 98%) i300μm, uye huwandu hwezvimedu husingasviki 74μm (200 mesh) hausi pasi pe75%. Kunyatsonaka kweslurry yemvura yemarasha yekupa gasification hwakakora zvishoma pane hweslurry yemvura yemarasha yemafuta. Muganho wepamusoro wehukuru hwezvimedu unobvumirwa kusvika 1410μm (14 mesh), uye huwandu hwezvimedu husingasviki 74μm (200 mesh) i32% kusvika 60%. Kuti slurry yemvura yemarasha ive nyore kupomba uye kuita atomize, slurry yemvura yemarasha ine zvinodiwawo kuti itsvedzerere.
Pakupisa kwemumba uye kucheka kwemvura kwe100s, kupenya kwemvura kunowanzo fanirwa kunge kusiri pamusoro pe1000-1500mPas. Kupenya kwemvura yemarasha kunoshandiswa mukutakura mapaipi kure kunoda kupenya kwemvura kusingapfuure 800mPa·s pasi pekupisa kwakaderera (kupisa kwakaderera kwegore kwemapaipi akavigwa pasi pevhu) uye kupenya kwemvura kwe10s-1. Pamusoro pezvo, zvinodikanwawo kuti kupenya kwemvura yemarasha kuve nekupenya kwakaderera kana kuri mumamiriro ekuyerera, izvo zviri nyore kushandisa; kana yamira kuyerera uye iri mumamiriro ekumira, inogona kuratidza kupenya kwakakwirira kuti ive nyore kuichengeta.
Kugadzikana kwetsvina yemvura yemarasha panguva yekuchengetera nekutakura kwakakosha zvikuru, nekuti slurry yemvura yemarasha musanganiswa wezvikamu zvakasimba nezvinyoro, uye zviri nyore kuparadzanisa chakasimba nezvinyoro, saka zvinodikanwa kuti pasave ne "slurry yakaoma" inogadzirwa panguva yekuchengetera nekutakura. Iyo inonzi "slurry yakaoma" inoreva precipitation isingagoni kudzorerwa pamamiriro ayo ekutanga nekukurunga slurry yemvura yemarasha. Kugona kweslurry yemvura yemarasha kuchengetedza kushanda kwekusaburitsa mvura yakaoma kunonzi "kugadzikana" kweslurry yemvura yemarasha. Slurry yemvura yemarasha isina kugadzikana zvakanaka ichakanganisa zvakanyanya kugadzirwa kana mvura yanaya panguva yekuchengetera nekutakura.
II. Pfupiso yeTekinoroji yeKugadzirira Sira yeMarasha neMvura
Mvura yemarasha inoda kuwanda kwemarasha, saizi yezvidimbu zvidiki, kuyerera zvakanaka, uye kugadzikana kwakanaka kudzivirira kunaya kwemvura kwakaoma. Zvichave zvakaoma kusangana nezvinhu zvese zvataurwa pamusoro apa panguva imwe chete, nekuti zvimwe zvacho zvinodziviswa. Semuenzaniso, kuwedzera kuwanda kuchaita kuti viscosity iwedzere uye kuyerera kwayo kuore. Kuyerera kwakanaka uye kuderera kwe viscosity kuchaita kuti kugadzikana kuwedzere. Saka, zvakakosha kutarisa kuwanda kwayo munguva chaiyo.Lonnmetermita yekubata vanhu nemaokoine kururama kunosvika 0.003 g/ml, izvo zvinogona kuyera huwandu hwemvura uye kudzora huwandu hwemvura.
1. Sarudza Marasha Asina Kugadzirwa Nesimba Nemazvo
Pamusoro pekuzadzisa zvinodiwa nevashandisi vari pasi pemvura, mhando yemarasha ekushandisa pakuchera inofanirawo kutarisa hunhu hwayo hwekushandisa pakuchera - kuoma kwekushandisa pakuchera. Mamwe marasha ari nyore kugadzira slurry ine mvura yakawanda yemarasha mumamiriro ezvinhu akajairwa. Kune mamwe marasha, zvakaoma kana kuti zvinoda nzira yakaoma yekudhinda uye mutengo wakakwira kugadzira slurry ine mvura yakawanda yemarasha. Hunhu hwekushandisa pakuchera hune simba guru pakudyara mari, mutengo wekugadzira uye mhando yeslurry ine mvura yemarasha yemuchina wekudhinda. Naizvozvo, mutemo wehunhu hwekushandisa pakuchera marasha unofanirwa kudzidzwa, uye marasha asina kubikwa ekushandisa pakuchera anofanira kusarudzwa zvichienderana nezvinodiwa chaizvo uye misimboti yekugoneka kwehunyanzvi uye kunzwisisa kwehupfumi.
2. Kunyora mamakisi
Kutsvedza kwemvura yemarasha hakungodi chete kuti saizi yezvikamu zvemarasha isvike pakukora kwakatarwa, asiwo kunoda kugoverwa kwakanaka kwezvikamu, kuitira kuti zvikamu zvemarasha zvehukuru hwakasiyana zvigone kuzadzana, kuderedza mipata iri pakati pezvikamu zvemarasha, uye kuwana "kushanda zvakanaka kwekuunganidza". Mipata mishoma inogona kuderedza huwandu hwemvura inoshandiswa, uye zviri nyore kugadzira slurry yemvura yemarasha ine huwandu hwakawanda. Iyi tekinoroji dzimwe nguva inonzi "grading".
3. Maitiro ekubvisa pulp nemidziyo
Pasi pehunhu hwehukuru hwezvimedu zvemarasha zvisina kubikwa uye mamiriro ekukweshwa, maitiro ekuita kuti kugoverwa kwehukuru hwezvimedu zvechigadzirwa chekupedzisira chemarasha nemvura yemarasha kubudirire zvakanyanya kunoda kusarudzwa kwakaringana kwemidziyo yekukwesha uye maitiro ekushandisa pulping.
4. Kusarudza Zvimwe Zvinoenderana Nekushanda
Kuti slurry yemvura yemarasha iwane huwandu hwakawanda, viscosity yakaderera, uye rheology yakanaka uye kugadzikana, huwandu hushoma hwemakemikari, anonzi "zvinowedzera", hunofanirwa kushandiswa. Mamorekuru ekuwedzera anoshanda pakubatana pakati pezvikamu zvemarasha nemvura, izvo zvinogona kuderedza viscosity, kuvandudza kupararira kwezvikamu zvemarasha mumvura, uye kuvandudza kugadzikana kweslurry yemvura yemarasha. Huwandu hwezvinowedzera hunowanzova 0.5% kusvika 1% yehuwandu hwemarasha. Kune mhando dzakawanda dzezvinowedzera, uye fomura haina kugadziriswa uye inofanira kutsanangurwa kuburikidza nekutsvagisa kwekuyedza.
