Nzira yekuziva madota enhunzi

Madota enhunzi emazuva ano ane sulfide yakawanda kana sulfate (yakadai segypsum, nezvimwewo), iyo yakasiyana nedota renhunzi. Kana ikashandiswa mukongiri pasina kuyedza, inokonzeresa kutsemuka kwekongiri uye kuparara. Kunyangwe iwo azvino madota enhunzi aine SO 3 zvirambidzo zvemukati, kuongororwa uye kutsunga kwe "desulfurized ash" kushomeka.

(2) "Denitration ash"
Kuti uderedze kubuda kweNO x mukupisa kwemarasha, zvinofanirwa kuita "denitration" kurapwa panguva yekupisa marasha. Kusaita denitration maitiro kunogona kukonzera imwe yasara NH4 munhunzi dota. Kana madota enhunzi akasanganiswa nesamende, ichasangana nealkali Nzvimbo yakasikwa ichasunungura NH 3 (ammonia gas), iyo inogadzira gasi rakawanda muchikamu chepurasitiki chekrete.

(3) "Madota matema anoyangarara"
Mune tekinoroji yemazuva ano yekupisa marasha, kuitira kuvandudza kugona kwekupisa kwemarasha kana zvimwe zvakakosha zvekushandisa zvinodiwa zvemagetsi emagetsi, dizeli kana zvimwe zvinhu zvine mafuta zvinowedzerwa sezviyamuro zvinopisa mukupisa kwemarasha. Izvi zvinopisa zvinopisa hazvigoni kupiswa zvachose uye zvicharamba zviri mumadota enhunzi. Mafuta. Kunyanya mushure mekunge nhunzi yarongerwa, iyo yakaunganidzwa nhunzi ash ichava nemafuta akawanda asina kupiswa, ayo anoshandiswa kusanganisa kongiri. Mafuta aya anoyangarara kumusoro uye anoita semafuta matema ari kuyangarara ari mukongiri. Dota renhunzi rerudzi urwu rinonzi "floating black ash".

Nzira yekuziva sei?
(1) Kuona sei
Vaongorori vane ruzivo vanogona kazhinji kuziva kunaka uye kupera kwekupisa kwedota renhunzi nekutarisa chete ruvara rwenhunzi.
Kuonekwa kwedota renhunzi kwakafanana nesamende, uye ruvara rwakasiyana kubva kuchena mukaka kusvika kune grey-dema. Rudzi rwenhunzi ash chiratidzo chakakosha chemhando inogona kuratidza huwandu uye musiyano weiyo kabhoni yemukati, uye kune imwe nhanho, inogona zvakare kuratidza nhunzi dota. The fineness. Kusviba kweruvara, ndiko kukwenenzvera saizi yenhunzi yenhunzi uye kuwedzera kabhoni.

Fly ash yakakamurwa kuita yakaderera-calcium fly ash uye high-calcium fly ash. Kazhinji, ruvara rwe-high-calcium fly ash i yellowish, uye ruvara rwe low-calcium fly ash i grayish. Madota enhunzi ane mucherechedzo wemuzinga une huchi hwakakura hune nzvimbo yakakura chaiyo uye yakakwirira adsorption chiitiko. Iyo particle size inotangira kubva 0.5 kusvika 300 μm. Pamusoro pezvo, mudhuri webead une porous structure ine porosity yakakwira kusvika 50% kusvika 80%, uye ine simba rekunyudza mvura.

Mukuwedzera kune chitarisiko chechisikigo, iwe unogona zvakare kuwedzera mvura uye kumutsa kuti ucherechedze nhunzi madota. Mubeaker yemvura, wedzera huwandu hwakakodzera hwenhunzi kuti ukurumidze kuvhenganisa zvakaenzana kutarisa kana pane madota matema arikuyerera pamusoro pemvura kutarisa huwandu hwekabhoni mumadota enhunzi; kana ruvara rwenhunzi idota rakasviba uye rine kunhuhwirira kwakasiyana, Madonhwe eOiri, rudzi urwu rwenhunzi runofanira kunge rwuchiyangarara putty uye runofanira kudzoserwa.

Mushure mokunge desulfurization ash ine yakakwirira yemahara CaO uye SO3 inomutswa nemvura, mhinduro inova alkaline, uye phenolphthalein reagent inodonhedzwa mairi, iyo inoratidzika yakatsvuka. Kuitira kudzivirira kongiri kubva pakutsemuka nekuda kwekuwedzera kwevhoriyamu yeCa (OH) 2 uye hydrated calcium sulfoaluminate, chigadzirwa chinofanira kudzoserwa.

Chechipiri, unogona kunhuwa hwema. Tora dota rakakodzera renhunzi nesimende mubeaker woisa mvura wokurunga kuita slurry. Kana iwe uchigona kunhuwa kunhuhwirira kweammonia, iyo nhunzi dota inogona kutongwa se denitrified ash.

Tarisa nemaikorosikopu! Kuziva madota emanyepo, kutanga kusefa. Kazhinji, madota anobhururuka ane saizi diki anotsvedzerera uye girazi rakatenderera pasi pemaikorosikopu (uchishandisa maikorosikopu iri pamusoro peka100), uye pamusoro pezvikamu zvine saizi yakakura haina kurongeka asi zvakare Yakatenderedzwa. Kana yakawandisa pasi jecha hupfu, hupfu hwematombo, boiler slag poda yakasanganiswa, pachave neakawanda asina kujairika zvimedu mune yega yega saizi saizi nhanho, kunyanya mudiki diki saizi nhanho, inozoonekwa isingaite uye angular.

Ndinofanira kutakura maikorosikopu kuti ndisiyanise here? Nzira iri nyore ndeiyi: tora zvishoma zvingangoita 1kg yenhunzi woisa mudhishi, woisa mvura kwairi, wokurunga uchiwedzera mvura kusvika yava kuzara, woona kana pane jira jena rinoyangarara pamusoro paro. pamusoro pemvura, kana paine Chokwadi, kana ikasadaro, inhema.

For fly ash, kutanga sieving. Kazhinji kutaura, nhunzi dzemadota ekirasi madiki madiki ane mabhora egirazi akatsetseka pasi pemaikorosikopu, uye pamusoro pezvikamu zvekirasi yakakura particle size haina kujairika asi yakatenderedza. Kana yakawandisa pasi jecha hupfu, hupfu hwebwe, boiler slag poda yakasanganiswa, pachave neakawanda asina kujairika zvimedu mukirasi yega yega saizi yechikamu, kunyanya mukirasi diki diki saizi.

Madota enhunzi chaiwo ane zvimiro zvepasirese uye zvimiro zvemashandisirwo, pamwe nekusimba kwemakemikari kuumbwa uye radioactivity zviyero. Packaging zvirevo, zvakajeka giredhi zviyero. Muvara wakasviba uye wero, upfu, zvimedu zvakanaka kwazvo, ruoko rwunonzwa rwakanaka uye rwakaoma, uye hunyoro hwakaderera. Madota enhunzi emanyepo anonyanya kugadzirwa nehupfu hwematombo, hupfu hwezvidhinha hwakakanyiwa nedota shoma renhunzi kana slag, uye zvimwe kana zvese zvaro zvakaputirwa zvakananga nehupfu hwematombo. Fly fly ash pachayo haina viscous uye haina basa. Ruvara rwakachena, uye mamwe mavara haana kuchena zvakanyanya. Ruoko rwunonzwa rwakakasharara, rwakanyorova, uye bhegi rekurongedza harina kurongeka. Teerera kune zviri pamusoro apa paunenge uchitenga nhunzi ash kuti uone kuti unogona kutenga emhando yepamusoro nhunzi ash.

(2) Nzira yekuita sampling yekubvuma?
Shandura iyo yechinyakare sampling nzira uye chinzvimbo, ndiko kuti, weld yakakosha sampling pombi pane inonhunzi dota ichidyisa simbi pombi ine dhayamita ye100mm pakureba kwemamita 1.5 kubva pasi, iyo inogona kusarudzwa chero nguva panguva fly ash unloading process. Tora sampuli uye uzivise pachena mutengesi wenhunzi kuti kana mhedzisiro yemasampuli maviri akaonekwa akasiyana mumotokari imwe chete, vanorangwa zvakaomarara.
