Coal mill equipment sarudzo 1: yakaderera-speed marasha chigayo

Iyo yakajairika mumiriri we low speed coal mill ndiyo bhora rechigayo.Musimboti wekushanda ndewekuti: mota ine simba guru kuburikidza negiya bhokisi kutyaira iyi inorema denderedzwa ndiro inotenderera, bhora resimbi riri munyore rinotenderedzwa kusvika pahumwe kureba robva rawira pasi, kuburikidza nekukanganisa kwebhora resimbi pamarasha uye pakati. bhora resimbi, pakati pebhora resimbi nendiro yevarindi, marasha anokuyiwa.Marasha akanyanya-akakora asina kukwana anopatsanurwa kana achiyerera nepakati pehupfu hwakakasharara kuseri kwechigayo chebhora, uye obva atumirwa kune denderedzwa ndiro kubva pakudzoka poda chubhu yekukuya zvakare.Pamusoro pekutakura hupfu hwemarasha, mhepo inopisa inoitawo basa rekuomesa marasha.Nokudaro, mhepo inopisa inonziwo desiccant muupfu system.Chigadzirwa chacho chine maitiro enguva yakareba inoramba ichishanda nguva, kugadzirisa nyore, kugadzikana kwakagadzikana uye kunaka, simba guru rekuchengetedza, kukurumidza kupindura, kushanduka kukuru kwekushanda, kuderera kwemhepo-coal ratio, kuchengetedza marasha emagetsi ekuchengetedza, yakawanda yekukuya marasha nezvimwe zvakadaro.Inonyanya kushandiswa kuoma uye zvepakati-kuoma marasha, kunyanya kune marasha ane yakanyanya kuvhurika zvemukati uye yakasimba abrasive midziyo.Zvakadaro, ichi chigayo chebhora chinomhanya-pasi chakakura, chine masimbi makuru ekushandisa, chinotora ivhu rakawanda, uye chine mari yekutanga mari.Saka chigayo chebhora chakakodzera kushanda kwemutoro wakazara.

Chigayo chemarasha mhando 2:medium speed marasha chigayo 

Iyo yepakati inomhanya marasha chigayo inozivikanwa zvakare seyakamira marasha chigayo, icho chinoratidzwa nezvikamu zvekukuya zvinoumbwa nemapoka maviri ehukama hwekufamba kwemuviri unokuya.Marasha anosvinwa uye anogayirwa pakati pemiviri miviri inokuya uye inopwanyika.Panguva imwecheteyo, mhepo inopisa kuburikidza neguyo inoomesa marasha uye inotumira marasha akapwanyika kune chinoparadzanisa panzvimbo yepamusoro yeguyo.Mushure mekuparadzana, marasha akapwanyika eimwe saizi yechimwe chikamu anotorwa kubva muguyo nekuyerera kwemhepo, uye mazimbe akaomarara akapwanyika anodzoserwa kunzvimbo yekukuya kuti idzoke.Iyo yepakati inomhanya marasha chigayo ine zvakanakira compact midziyo, diki tsoka, simba rekushandisa kuchengetedza (inenge 50% ~ 75% yebhora chigayo), yakaderera ruzha, yakareruka uye inonzwisisika mashandiro ekutonga.Asi harikodzeri kukuya marasha akaomarara.

Coal mill equipment kusarudzwa 3: high-speed marasha chigayo

Kumhanya kwechigayo chemarasha akakwira 500 ~ 1500 r/min, iyo inonyanya kuumbwa ne-high-speed rotor uye goko rekukuya.Common feni kugaya uye nyundo kugaya uye zvichingodaro.Muchigayo, marasha anopwanywa nekudhumhana kuripo pakati pekumhanya kwepamusoro-soro uye goko rekukuya uye kubonderana kwemarasha.Rudzi urwu rwemarasha chigayo uye pulverized marasha separator inoumba rose, chimiro chiri nyore, compact, yekutanga inivhesiti yakaderera, kunyanya yakakodzera kukuya yakakwira mwando lignite uye yakakwirira inoputika kugutsikana, nyore kukuya bituminous marasha.Nekudaro, nekuti ndiro inokonzeresa yakanyura uye inopfekwa nekuyerera kwemhepo, hupenyu hwayo hwesevhisi hunowanzo kungosvika 1000h kana ichikuya lignite, kudzokororwa kazhinji, uye mvura yemarasha epasi haifanirwe kunge yakanyanya kukwirisa, ayo anowanzo kushandiswa yakananga inofefetedza boilers muzvidyarwa zvemagetsi, uye haifanirwe kushandiswa kukuputika kwechoto jekiseni mashopu.

Aya matatu ari pamusoro emhando yemarasha ekukuya emidziyo sarudzo ane zvakanakira nekuipira, pakusarudza marasha ekukuya midziyo, zvinodikanwa kufunga nezve kusarudzwa kwese kwepulverizing system.Iyo poda system inogona kukamurwa kuita mapoka maviri: yakananga kuvhuvhuta mhando uye yepakati yekuchengetedza mhando (inonzi semhando yekuchengetedza).Muchigayo chemarasha chinoputika, marasha anogayiwa kuva marasha akapwanyika nechigayo chemarasha obva afuridzirwa akananga muchoto kuti apise.Mukuchengetedza pulverization system, marasha akapwanyika anotanga kuchengetwa mubhini remarasha, uye zvino zvichienderana nezvinodiwa zvebhailer mutoro, marasha akapwanyika anotumirwa kubva mubhini remarasha akaputswa kuenda kuchoto kuti apiswe neanopisa.Yakasiyana pulverizing masisitimu zvakare akakodzera kune akasiyana marudzi emarasha uye marasha ekukuya michina kusarudzwa.Zvinoenderana neiyo pulverization system, takapfupikisa hwaro hunotevera hwekusarudzwa kwechigayo chemarasha:

(1) Steel bhora chigayo mukati mekuchengetedza bhini mhando inopisa air powder system: inogona kushandiswa kune anthracite (Vsr <9%) uye kupfeka mune yakasimba pamusoro pemarasha.

(2) Bhora chigayo chepakati chekuchengetera rudzi chinopedza gasi poda yekuendesa system: inonyanya kushandiswa kwemarasha ane simba rinopfeka uye yepakati inoputika (Var-19% ~ 27%) bituminous marasha.

(3) Double-in-double-out steel ball mill direct blowing system 22-241: yepakati-yakakwirira inoputika (Vs.7-27% ~ 40%) bituminous marasha.

(4) Medium-speed coal mill direct blowing system: yakakodzera kukuya bituminous marasha ane high volatile content (Vanr-27%~40%), yakakwira mwando (external mwando Mp≤15%) uye kupfeka kwakasimba, pamwe nemarasha. kurasikirwa kwenhema kuzasi kwakasimba, kushanda kwemarasha kunobvira, uye marasha emarasha akapwanyika anoenderana nezvinodiwa zvechigayo chemarasha.

(5) Fan mill yakananga kuvhuvhuta system: yakakodzera lignite erosion kupfeka index Ke≤3.5 uye 50 MW uye pazasi bituminous marasha unit bhaira
