1.1 Pfupiso yefekitori yekugadzirira marasha
Chivako cheLongquan Coal Preparation Plant cheTaiyuan Coal Gasification Company ikambani yakakura ine magadzirirwo maviri ine simba rekugadzira re5.00Mt/a iyo inonyanya kugadzira marasha ekubikisa uye inotarisa kugadzirwa kwemarasha anodziya. Sisitimu yesimbi yakaoma yefekitari yekugadzira marasha inoita 5% yehuwandu hwemarasha asina kubikwa uye ine simba rekugadzirisa re56.82t/a paawa.
1.2 Maitiro ekuronga
Maitiro ekugadzira marasha pakugadzira fekitari yekugadzirira marasha ndeekuti: Mushure mekunge marasha asina kucheneswa abviswa uye avharwa (chidzitiro chekudzima marasha i1mm), 50~1mm inoparadzaniswa nedutu remhepo rinobvisa marasha uye risina kumanikidzwa rine zvinhu zvitatu, 1~0.25mm. Slime yemarasha yakaoma inoparadzaniswa neTBS, uye slime yemarasha yakanaka -0.25mm inodzoserwa nekukora uye kusvina sechigadzirwa chemarasha chepakati.
2.1 Kuparadzanisa uye kugadzirisa matope akaomarara usati wachinja tekinoroji
Maitiro ekuparadzanisa nekudzoreredza matope akaomarara asati achinja tekinoroji yeLongquan Coal Preparation Plant ndeaya: kuwanda kwemhepo ine dutu + kupatsanurwa kweTBS + kuwanda kwemhepo ine dutu + kucheneswa kwearc sieve desliming uye dewatering + kubvisa mvura mu centrifuge. Maitiro acho anoratidzwa muMufananidzo 1.
Mufananidzo 1. Chati yekuyerera kwemaitiro ekuparadzaniswa kwetsvina yakaoma isati yatanga kushanduka kwetekinoroji
2.2 Pane dambudziko
Tafura 1 inoratidza data rekuyera sieve rechinhu chakakombama chinopinzwa uye pamusoro pechidzitiro apo sieve yakakombama yakashandiswa kucheka nekuronga huwandu hweTBS concentrate isati yatanga shanduko yehunyanzvi. Kubva pakuenzanisa data rekuyera sieve, zvinogona kuonekwa kuti musiyano uripo pakati pehuwandu hwedota rechinhu chinouya nesieve uri pasi pe5%, izvo zvinoratidza kuti kushanda zvakanaka kwesieve yearc kwakaderera uye mhedzisiro yekuderedza dota yakaderera zvikuru.
Tafura 1. Data rekuongorora re arc sefa isati yatanga kushandurwa kwetekinoroji.
Chigayo chekugadzira marasha cheLongquan chine dota rakawanda, dota guru regangue, dota remukati rakawanda, goho shoma, uye goho guru repakati. Saka, mukugadzirwa chaiko, dhizaini yekutanga yekuparadzanisa madota nemaitiro ekudzoreredza madota ine matambudziko anotevera:
Maitiro ekutanga anoshandisa sikirini yakaita searc ine kushanda kwakaderera kwekudzivirira kucheka matope akakora, madhaka uye kubvisa mvura yakawanda muTBS concentrate. Nekuda kwedambudziko guru remadhaka egangue mumarasha asina kubikwa uye huwandu hwakawanda hwematope akakora, zvinozokonzeresa kuti: sikirini yakakombama ine matope akakora, zvichikonzera huwandu hwakawanda hwemadhaka akakora uye akachena; sikirini yakakombama inoshandisa simbi isina tsvina. Sikirini ine slotted ine gap hombe yechidzitiro uye iri nyore kupfeka, izvo zvinoita kuti huwandu hwakawanda hwematope akakora arasike uye arasikirwe nemarasha akakora. Panguva imwe chete, sikirini inofanira kuchinjwa nguva nenguva.
3.1 Hurongwa hwekushandura tekinoroji
Kuti vawedzere mwero wekudzoreredzwa kwemari yemarasha akachena uye mabhenefiti ehupfumi, Longquan Coal Preparation Plant yakabatana neAnhui Fangyuan Plastic Co., Ltd. kushandura sisitimu yekuparadzanisa marasha akaomarara. Mushure mekuratidzira, yakashandisa zvakananga Anhui Fangyuan Plastic Co., Ltd. kugadzira kushanda zvakanaka kwekuongorora, FY-HVS-1500 laminated high-frequency screen ine simba rakanaka rekudzima simbi inotsiva skrini yakakombama kuti icheke chigadzirwa cheTBS overflow uye ichivhare zvinobudirira.
3.2 Maumbirwo uye musimboti wekushanda kwechidzitiro cheFY-HVS-1500 chine mafrequency akawandisa.
Fangyuan FY-HVS-1500 high-frequency stacked screen rudzi rwemichina inoshandisa high-frequency vibration ye screen pamusoro uye simba rechinhu kuti iwane kupatsanurwa zvichienderana nehukuru hwe particle yezvinhu. Maumbirwo ayo anonyanya kuumbwa nemugovanisi, feeder, uye ma screen frames epamusoro nepazasi. , High-frequency vibration motor, product collection hopper pa screen, product collection tank pasi pe screen, furemu uye support platform. Musimboti wekushanda we sieve muchina unoratidzwa muMufananidzo 2. Maonero ayo makuru uye zvakanakira ndeizvi zvinotevera.
Mufananidzo 3 Nzvimbo yekuongorora marasha akaunganidzwa
Chigayo chekugadzira marasha cheLongquan chine dota rakawanda, dota guru regangue, dota remukati rakawanda, goho shoma, uye goho guru repakati. Saka, mukugadzirwa chaiko, dhizaini yekutanga yekuparadzanisa madota nemaitiro ekudzoreredza madota ine matambudziko anotevera:
Maitiro ekutanga anoshandisa sikirini yakaita searc ine kushanda kwakaderera kwekudzivirira kucheka matope akakora, madhaka uye kubvisa mvura yakawanda muTBS concentrate. Nekuda kwedambudziko guru remadhaka egangue mumarasha asina kubikwa uye huwandu hwakawanda hwematope akakora, zvinozokonzeresa kuti: sikirini yakakombama ine matope akakora, zvichikonzera huwandu hwakawanda hwemadhaka akakora uye akachena; sikirini yakakombama inoshandisa simbi isina tsvina. Sikirini ine slotted ine gap hombe yechidzitiro uye iri nyore kupfeka, izvo zvinoita kuti huwandu hwakawanda hwematope akakora arasike uye arasikirwe nemarasha akakora. Panguva imwe chete, sikirini inofanira kuchinjwa nguva nenguva.
3.1 Hurongwa hwekushandura tekinoroji
Kuti vawedzere mwero wekudzoreredzwa kwemari yemarasha akachena uye mabhenefiti ehupfumi, Longquan Coal Preparation Plant yakabatana neAnhui Fangyuan Plastic Co., Ltd. kushandura sisitimu yekuparadzanisa marasha akaomarara.

Mufananidzo 4 Wakashongedzerwa nechidzitiro che polyurethane chakasimbiswa nefiber chakatenderera
Chigadzirwa cheLongquan Coal Preparation Plant chakagadzirisa maitiro ekuparadzanisa nekupatsanura marara emhando ye "coarse slime", uye chakashandisa masikirini e "high-frequency screens" anoshanda zvakanyanya uye anoshanda zvakanaka panzvimbo pemasikirini e "arc" kuti avhare uye aronge zvigadzirwa zve "coarse slime", zvichideredza huwandu hwezvigadzirwa zve "coarse slime". Kuwanda kwedota nevhu rakatsetseka kunoita kuti huwandu hwedota rechigadzirwa che "coarse clean" chekupedzisira huve hwakaderera pane huwandu hwedota hunodiwa nemarasha ese akachena. Panguva imwe chete, dambudziko rekumhanya zvisina kurongeka pasi pesefa rinogadziriswa zvinobudirira. Kuyedzwa kwefekitori yekugadzirira marasha kwakaratidza kuti huwandu hwedota re "coal slurry" pasi pesefa hwakawedzera kubva pasi pe55% kusvika kupfuura 65%, uye goho resefa rakawedzera neanenge 5% zvichienzaniswa ne "arc seeve", uye kubatsirwa kwehupfumi kwefekitori yekugadzirira marasha kwakavandudzika zvikuru.
