Uruganda rwamakara nigice cyingenzi cya sisitemu ya pulverizing hamwe nibikoresho byingenzi byingufu zingufu mumashanyarazi.Igikorwa cyacyo nyamukuru ni ugusenya no gusya amakara mu makara yangiritse kugirango itange ibikoresho byo guteka, iboneza ryayo bizagira ingaruka ku mutekano n’ubukungu by’ikigo.Kubera ko guhuza amakompanyi atandukanye y’amakara ku bwoko butandukanye bw’amakara biratandukanye cyane, ufatanije n’imiterere nyayo y’ikwirakwizwa ry’amakara mu Bushinwa mu buryo butaringaniye mu Bushinwa, ubwiza bw’ibicuruzwa by’amakara bizagira ingaruka ku bukungu bwa sisitemu ya pulverizing.None, gutoranya ibikoresho byo gusya amakara bigomba gutoranywa gute?Imashini za HCMnk'uruganda rukora amakara, ruzashyiraho ishingiro ryo gutoranya amakara.Hariho ubwoko bwinshi bwuruganda rwamakara, ukurikije umuvuduko wibice byo gusya byicyiciro cyicyiciro cyo gutoranya ibikoresho byamakara bishobora kugabanywamo ubwoko butatu, aribwo: uruganda rwamakara rwihuta, uruganda rwamakara rwihuta hamwe n’uruganda rwihuta rwamakara. .Ibikurikira bizerekana guhitamo ibi bikoresho bitatu byo gusya amakara.
Guhitamo ibikoresho byamakara 1: uruganda rwamakara yihuta
Ubusanzwe uhagarariye uruganda rwamakara rwihuta ni urusyo rwumupira.Ihame ryakazi ni: moteri ifite ingufu nyinshi zinyuze muri gare kugirango itware iyi plaque iremereye izunguruka, umupira wibyuma muburyo bworoshye uzunguruka muburebure runaka hanyuma ugwa hasi, binyuze mumupira wumupira wicyuma kumakara no hagati umupira wibyuma, hagati yumupira wicyuma nisahani yizamu, amakara arahari.Amakara arenze urugero atujuje ibyangombwa aratandukana iyo anyuze mumashanyarazi atandukanya inyuma yumusyo wumupira, hanyuma akoherezwa kumasahani yumuzingi avuye mumashanyarazi agaruka kugirango yongere asya.Usibye gutwara ifu yamakara, umwuka ushyushye unagira uruhare mukumisha amakara.Kubwibyo, umwuka ushyushye nanone witwa desiccant muri sisitemu yifu.Igicuruzwa gifite ibiranga igihe kirekire cyo gukora gikomeza, kubungabunga byoroshye, umusaruro uhamye kandi mwiza, ubushobozi bunini bwo kubika, igisubizo cyihuse, imikorere nini ihindagurika, igipimo gito cy’amakara y’amakara, kuzigama imashini y’amakara y’ibicuruzwa, intera nini yo gusya amakara n'ibindi.Ikoreshwa cyane cyane ku makara akomeye kandi aciriritse, cyane cyane ku makara afite ibintu byinshi bihindagurika kandi bifite imitungo ikomeye.Nyamara, uru ruganda rwihuta rwumupira ni runini, rufite ibyuma byinshi, rufite ubutaka bwinshi, kandi rufite ishoramari ryambere.Urusyo rwumupira rero rurakwiriye gukora imitwaro yuzuye.
Ibikoresho by'amakara ubwoko bwa 2:uruganda rwihuta rwamakara
Uruganda rwihuta rwamakara ruzwi kandi nkuruganda rwamakara ruhagaritse, rurangwa nibice byo gusya bigizwe nitsinda ryibice bibiri byimikorere yumubiri usya.Amakara arayanyunyuza hasi hagati yubuso bwimibiri yombi isya kandi irajanjagurwa.Muri icyo gihe, umwuka ushyushye unyuze mu ruganda wumisha amakara kandi wohereza amakara ya pulverised kubitandukanya mugice cyo hejuru cyurusyo.Nyuma yo gutandukana, amakara yangiritse afite ubunini buke asohoka mu ruganda hamwe n’umwuka uhumeka, hanyuma amakara yangiritse asubizwa mu gusya kugira ngo yongere yongere.Uruganda rwamakara rwihuta rufite ibyiza byibikoresho byoroheje, ibirenge bito, kuzigama ingufu (hafi 50% ~ 75% byurusyo rwumupira), urusaku ruke, urumuri no kugenzura imikorere yoroheje.Ariko ntibikwiye gusya amakara akomeye.
Guhitamo ibikoresho byamakara 3: uruganda rwihuta rwamakara
Umuvuduko wuruganda rwihuta rwamakara ni 500 ~ 1500 r / min, ugizwe ahanini na rotor yihuta cyane hamwe no gusya.Gusya kwabafana bisanzwe no gusya inyundo nibindi.Mu ruganda, amakara yajanjaguwe no kugongana hagati y’umuvuduko mwinshi n’igikonoshwa no kugongana hagati yamakara.Ubu bwoko bwuruganda rwamakara hamwe nogutandukanya amakara bigizwe byose, imiterere iroroshye, yoroheje, ishoramari ryambere ni rito, cyane cyane rikwiriye gusya lignite yubushyuhe bwinshi nibirimo byinshi bihindagurika, byoroshye gusya amakara ya bituminiyumu.Nyamara, kubera ko isahani y’ingaruka yangirika kandi ikambarwa n’ikirere, ubuzima bwayo muri rusange ni nka 1000h gusa iyo usya lignite, ugasimburwa kenshi, kandi amazi y’amakara yo mu butaka ntagomba kuba menshi cyane, ubusanzwe akoreshwa kuri Amashanyarazi ataziguye mu mashanyarazi, kandi ntagomba gukoreshwa mumahugurwa yo guteramo itanura.
Ubwoko butatu bwavuzwe haruguru bwo gutoranya amakara afite ibyiza nibibi, muguhitamo ibikoresho byo gusya amakara, birakenewe ko harebwa uburyo rusange bwo guhitamo sisitemu.Sisitemu ya poro irashobora kugabanywamo ibyiciro bibiri: guhita byerekanwa nubwoko bwo kubika hagati (byitwa ubwoko bwububiko).Muri sisitemu yo guhanagura mu buryo butaziguye, amakara ahindurwamo amakara yashegeshwe n'uruganda rw'amakara hanyuma agahita ajugunywa mu itanura kugira ngo yaka.Muri sisitemu yo kubika ububiko, amakara ya pulverized abikwa mbere yabitswe mumabuye yamakara, hanyuma akurikije ibikenerwa nu mutwaro utetse, amakara ya pulveri yoherejwe avuye mumabuye yamakara ajyanwa mu ziko kugirango yaka umuriro.Sisitemu zitandukanye za pulverizing nazo zirakwiriye muburyo butandukanye bwo guhitamo amakara hamwe no gusya amakara.Dukurikije gahunda ya pulverisation, twavuze muri make ishingiro rikurikira ryo gutoranya amakara:
.
.
.
. igihombo cyibinyoma munsi yimbaraga zikomeye, gutwika amakara birashya, kandi ubwiza bwamakara bwujuje ibisabwa nuruganda rwamakara.
.
Mu gutoranya ibikoresho by’uruganda rw’amakara, bigomba gusuzumwa hakurikijwe ibiranga gutwikwa, kwambara no guturika biranga amakara, ibiranga pulverisation y’uruganda rw’amakara hamwe n’ibisabwa kugira ngo amakara ahindurwe neza, ahujwe n’imiterere y’itanura n’imiterere yo gutwika. , kandi utekereze ku ishoramari, kubungabunga no gukora urwego rw'amashanyarazi n'ibikoresho bifasha, itangwa ry'ibicuruzwa, inkomoko y'amakara n'imyanda mu makara n'ibindi.Kugirango ugere ku mukino ufatika hagati ya sisitemu ya pulverizing, ibikoresho byo gutwika hamwe n’itanura, kugirango habeho umutekano nubukungu byikigo.Imashini za HCM zifite ubuhanga mu gukora uruganda rukora amakara yihuta, dukora HLM yuru ruganda rwamakara rwihuta rufite ibintu bikurikira:
.
(2) kugabanya imikorere ni byiza, umutekano kandi wizewe;Urusaku ruke rwo kwiruka no kunyeganyega;Imikorere ya kashe nibyiza kwemeza ko ifu yamakara itinjira mubice byose bizunguruka.
(3) Birakwiye gusya amakara akomeye, imbaraga zo gusya, gukora neza.Igikorwa gihamye kandi cyizewe.
(4) Gusya kwa MPS ntibibaho mubice bitavanze neza, kandi kwambara ibyuma ni bito.Niba ufite ikibazo cyo guhitamo ibikoresho byo gusya amakara, urakaza nezaImashini za HCM for the basis of coal mill selection, contact information:hcmkt@hcmilling.com
