The process flow of thedesulfurization vertical roller chigayosisitimu yakatsetseka, mari yacho inochengetedzwa uye manejimendi ekugadzira ari nyore.Paunosarudza chirongwa chekugadzira uye kusarudzwa kwemidziyo ye desulfurization limestone poda, maitiro matsva uye akavimbika matsva uye matekinoroji achagamuchirwa, ayo ari ehupfumi, anonzwisisika, anoshanda uye akavimbika.HCMilling(Guilin Hongcheng), sedhizaini dhizaini uye mugadziri we desulfurization vertical roller mill system, ichaunza desulfurization mhedzisiro yevertical roller mill.

HLMdesulfurization vertical roller chigayo

Zvinhu zvakati wandei zvinokanganisa kuita desulfurization:

1. Limestone giredhi

Limestone giredhi inotemwa neCaO yemukati.Iyo yepamusoro yeCaO yemukati yakachena limestone ndeye 56%.Iyo yakakwirira iyo limestone kuchena, zviri nani iyo desulfurization kunyatsoshanda.Semugadziri wekugadzira, paunenge uchigadzira zvigadzirwa, haufanirwe kungoverengera kuumbwa kwayo kwemakemikari, asi zvakare kunzwisisa maitiro ayo emuviri.Iyo calcium oxide yemukati yegiredhi rekutanga limestone ndeye 48% - 54%;Limestone haidi kuti yakakwira CaO yemukati.Limestone ine CaO> 54% ine kuchena kwepamusoro uye ine marmatized.Haisi nyore kugaya uye ine yakasimba kugadzikana kwemakemikari, saka haina kukodzera kushandiswa se desulfurizer.

2. Fineness of limestone powder

Iyo diki saizi yeimestone hupfu, iyo yakakura iyo chaiyo nzvimbo.Sezvo kunyungudutswa kwe limestone kuri kuita kwakasimba-mvura-maviri-chikamu kuita, uye chiyero chayo chekuita chakaenzana nenzvimbo chaiyo yezvimedu zve limestone, zvimedu zveraimestone zvakapfava zvine kuita kwakanaka kwekunyungudika, kukwira kwakasiyana kwakasiyana-siyana maitiro ekuita, yakakwirira desulfurization kunyatsoita uye. kushandiswa kwe limestone, asi iyo idiki iyo limestone particle size, iyo inokwirisa yekupwanya simba rekushandisa.Kazhinji, chiyero chekupfuura che limestone poda ichipfuura 325 mesh sieve (44 microns) i95%.

Panguva imwecheteyo, saizi yeimestone poda inobatana nemhando ye limestone.Kuti ive nechokwadi chekuti desulfurization inoshanda uye mwero wekushandiswa kwe limestone inosvika pane imwe nhanho, kana kusachena kuri mu limestone kwakakwira, limestone inofanira kunge yakatsetseka.

Limestone poda yekugadzira tekinoroji uchishandisa desulfurization vertical roller chigayosystem:

Kune FGD maitiro uchishandisa limestone poda sedesulfurizer, limestone poda inoda kuomarara mvura-mbiri-chikamu dissolution reaction, uye chiyero chekuita chiri chakanaka kune chaiyo nzvimbo yeraimu zvidimbu.Iyo diki saizi yeimestone poda zvidimbu ndeye, iyo yakakura iyo chaiyo nzvimbo nehukuru ndiyo.Iyo limestone particles ine yakanaka solubility, uye akasiyana-siyana ane hukama maitiro akakwira.Nekudaro, iyo idiki iyo particle size ye limestone, iyo inowedzera kushandiswa kwesimba rekupwanya.Kazhinji, chiyero chekupfuura che limestone poda ichipfuura 325 mesh sieve (44 microns) i95%.Panguva imwecheteyo, saizi yeimestone poda inobatana nemhando ye limestone.Kuti ive nechokwadi chekuti desulfurization inoshanda uye mwero wekushandisa limestone inosvika pane imwe nhanho, kana kusachena kuri mu limestone kwakakwira, limestone ichave yakatsetseka.Iyo yechinyakare chubhu chigayo tekinoroji inoshandiswa kugadzirira limestone poda, ine hombe yekushandisa simba, yakaderera kubuda, yakaoma process kuyerera, uye yakaoma kudzora kunaka uye particle grading.Nekuvandudzwa kwetekinoroji yekukuya, tekinoroji yekugaya yakagadzika inotambirwa.Nekuda kweiyo dhizaini yekukuya musimboti, kushandiswa kwesimba kwakadzikira (20-30% kuderera pane kushandiswa kwesimba kwechubhu chigayo), kemikari yechigadzirwa yakagadzikana, chidimbu chegiredhi chakafanana, uye kuyerera kuri nyore. .

Limestone inopinda muchirimwa inobudiswa muhopi nerori kana forklift, uye limestone inopwanyika mune imwe nhanho.Mabhuroki eraimestone anotumirwa kune crusher kuburikidza neplate feeder.Saizi yekudyisa inowanzodzorwa pa400-500mm, uye saizi yekuburitsa chidimbu inodzorwa ingangoita 15mm.Iyo limestone yakapwanyika inotumirwa mune limestone silo kuburikidza nemidziyo yekutakurisa, uye iyo silo yepamusoro inoshongedzerwa neinounganidza guruva imwe chete yekubvisa guruva.Iyo limestone yakapwanyika inoiswa meter uye inobatanidzwa nekumhanya inodzora bhandi reyerero pazasi pe silo, uye yobva yadyiswa mu vertical roller mill nebhandi conveyor yekukuya.Chigadzirwa chakapedzwa ndeye limestone poda ine fineness ye250 meshes.Iyo limestone poda mushure mekukuya inotakurwa kuenda kune yakapedzwa chigadzirwa chekuchengetedza kuchengetedza.Pamusoro peimba yekuchengetera zvinhu inoshongedzerwa neguruva rimwechete rekubvisa guruva.Zvigadzirwa zvakapedzwa zvinounzwa kune yakawanda tangi rori kuti iunzwe nemuchina wakawanda pazasi peimba yekuchengetera zvinhu.

Desulfurization effect yevertical roller chigayo:

Kukuya kweHLMvertical roller chigayo inotora iyo dhizaini yekukuya musimboti, ine inogadziriswa kugaya kumanikidza, yakaderera ruzha, yakaderera mashandisiro esimba, yakaderera kupfeka, kuchinjika kwakasimba kune zvinhu, nyore kuyerera kwemaitiro uye yakakwirira system kushanda zvakanaka.Iyo yese system inoshandiswa pasi pekumanikidzwa kwakashata nekusvibiswa kudiki kweguruva.Iyo nzira yekukuya ye vertical roller mill ine yunifomu yezviyo giredhi, inogadziriswa chigadzirwa kunaka (chigadzirwa fineness chinogona kusvika mazana matanhatu meshes kana kupfuura), uye kunaka kwechigadzirwa kunogona kuyerwa nekugadziriswa nekukurumidza.

Kana uine zvaunoda, ndapota taura nesu kuti uwane ruzivo rwemidziyo uye tipe ruzivo rwekutevera kwatiri:
