Nzira yekuziva dota renhunzi

Dota remazuva ano rine sulfide yakawanda kana sulfate (yakadai segypsum, nezvimwewo), izvo zvakasiyana nedota rekare remafuru. Kana rikashandiswa mukongiri pasina kuyedzwa, rinokonzera kutsemuka kukuru uye kuparara kwekongiri. Kunyangwe zviyero zvemafuru zvemazuva ano zvine zvirambidzo zveSO 3, kuongororwa uye kusarudzwa kwe "dota rakabviswa sulfuri" hazvina basa.

(2) "Dota rekubvisa tsvina"
Kuti kuderedze kuburitswa kweNO x mukupisa marasha, zvakakosha kuita mushonga we "denitration" panguva yekupisa marasha. Kubvisa marasha zvisina kunaka kunogona kukonzera imwe NH4 yasara muash inobhururuka. Kana ash inobhururuka yakasanganiswa nesimende, ichasangana nealkali. Nzvimbo yakasikwa ichaburitsa NH 3 (ammonia gasi), iyo inoburitsa gasi rakawanda muchikamu chepurasitiki chekongiri.

(3) "Dota dema rinoyangarara"
Mumichina yemazuva ano yekupisa marasha, kuitira kuvandudza kushanda zvakanaka kwekupisa marasha kana zvimwe zvinodiwa pakushanda kwemagetsi, dhiziri kana zvimwe zvinhu zvine mafuta zvinowedzerwa sezvinobatsira pakupisa marasha. Izvi zvinodzivirira kupisa hazvigoni kupiswa zvachose uye zvinoramba zviri muash inoputika. Oiri. Kunyanya mushure mekunge ash inoputika yagadziriswa, ash inounganidzwa inenge iine mafuta akawanda asina kupiswa, ayo anoshandiswa kusanganisa kongiri. Mafuta aya anoyangarara kumusoro uye anoonekwa semafuta matema anoyangarara mukongiri. Rudzi urwu rweash inoputika runonzi "ash nhema inoyangarara".

Vaongorori vane ruzivo vanowanzoziva kupfava uye kurasikirwa kwedota renhunzi nekungotarisa ruvara rwedota renhunzi.
Chitarisiko chedota remafuru chakafanana nesimende, uye ruvara rwacho runosiyana kubva pachena semukaka kusvika kugrey-dema. Ruvara rwedota remafuru chiratidzo chakakosha chehunhu chinogona kuratidza huwandu nemusiyano wehuwandu hwekabhoni, uye kusvika pamwero wakati, chinogonawo kuratidza dota remafuru. Kupfava kwaro. Kana ruvara rwakasviba, saizi yedota remafuru inopfava uye huwandu hwekabhoni hunokwira.

Dota remafungu rinokamurwa kuita dota remafungu rine calcium shoma uye dota remafungu rine calcium yakawanda. Kazhinji, ruvara rwedota remafungu rine calcium yakawanda rune ruvara rweyero, uye ruvara rwedota remafungu rine calcium shoma rune ruvara rwegrey. Zvidimbu zvedota remafungu zvine chimiro chemuzinga chine maburi ane nzvimbo yakakura uye basa rekuwedzera mvura yakawanda. Saizi yezvikamu izvi inotangira pa 0.5 kusvika 300 μm. Pamusoro pezvo, madziro edota ane chimiro chine maburi chine maburi ane maburi anosvika 50% kusvika 80%, uye anonyudza mvura zvakanyanya.

Pamusoro pechitarisiko chechisikigo, unogona zvakare kuwedzera mvura nekukurunga kuti uone dota remaputsi. Mubhokisi remvura, wedzera huwandu hwakakodzera hwedota remaputsi kuti ukurumidze kukurunga zvakaenzana kuti uone kana paine dota dema riri kuyerera pamusoro pemvura kuti uone huwandu hwekabhoni mudota remaputsi; kana ruvara rwedota remaputsi rwakasviba uye rune hwema hwakasiyana, madonhwe emafuta, rudzi urwu rwedota remaputsi rinofanira kunge riri kuyerera uye rinofanira kudzoserwa.

Mushure mekunge dota rine CaO2 uye SO3 rabviswa musulfurization, mvura inozosanganiswa, uye phenolphthalein reagent inodonhedzwa mairi, iyo inoita seyakatsvuka. Kuti kongiri isatsemuke nekuda kwekuwedzera kwehuwandu hweCa(OH)2 uye calcium sulfoaluminate yakanyungudutswa, chigadzirwa chinofanira kudzoserwa.

Chechipiri, unogona kunhuwidza hwema hwacho. Tora dota renhunzi nesimende rakakodzera mubeaker woisa mvura wokurunga kuti pave netsvina. Kana uchikwanisa kunhuwidza hwema hweammonia, dota renhunzi rinogona kuonekwa sedota risina hunyoro.

Tarisa nemaikorosikopu! Kuti uone dota renhema, tanga wavhara. Kazhinji, zvidimbu zvedota renhunzi zvine saizi diki zvakapfava uye girazi rakatenderera pasi pemaikorosikopu (uchishandisa maikorosikopu kanopfuura ka100), uye pamusoro pezvidimbu zvine saizi huru hazvina kuenzana asi zvakare Zvakaita sedenderedzwa. Kana upfu hwejecha rakakuyiwa, upfu hwematombo, uye upfu hweboiler slag hwakanyanya kusanganiswa, pachava nezvidimbu zvakawanda zvisina kuenzana padanho rega rega rehukuru hwezvidimbu, kunyanya padanho diki rehukuru hwezvidimbu, izvo zvinoita sezvisina kuenzana uye zvakatenderera.

Ndinofanira kutakura maikorosikopu kuti ndione kuti chii? Nzira iri nyore ndeiyi: tora 1kg yeash inobhururuka woiisa mudhishi, wobva wawedzera mvura mairi, wobva wasanganisa mvura kusvika yava kuda kuzara, woona kana paine jira remabhora machena ari pamusoro pemvura, kana iripo, kana isina, ndeyenhema.

Kana paine dota rinobhururuka, kutanga kuvharwa. Kazhinji, zvidimbu zvedota rinobhururuka zvemhando yezvikamu zvidiki zvine mabhora egirazi akapfava pasi pemaikorosikopu, uye pamusoro pezvidimbu zvemhando yezvikamu zvakakura hazvina kurongeka asi zvakada kuita denderedzwa. Kana upfu hwejecha rakakuyiwa, upfu hwematombo, uye upfu hweboiler slag hwakanyanya kusanganiswa, pachava nezvidimbu zvakawanda zvisina kurongeka mukirasi yega yega yezvikamu, kunyanya mukirasi yezvikamu zvidiki.

Dota remafuru rine mitemo yakasimba yenyika uye mashandisirwo aro, pamwe chete nemakemikari akasimba uye mwero weradioactivity. Mitemo yekurongedza, mitemo yakajeka. Ruvara rwacho dema neyero, hupfu, zvidimbu zvacho zvakanaka kwazvo, ruoko runonzwa zvakanaka uye rwakaoma, uye hunyoro hwakaderera zvikuru. Dota remafuru renhema rinogadzirwa zvakanyanya nehupfu hwematombo, hupfu hwezvidhinha hwakasanganiswa nehuwandu hushoma hwedota remafuru kana slag, uye rimwe kana rese rayo rakaputirwa zvakananga nehupfu hwematombo. Dota remafuru renhema pacharo harina kusimba uye harina basa. Ruvara rwacho ruchena, uye mamwe mavara haana kuchena. Kunzwa kweruoko kwakaoma, kwakanyorova, uye bhegi rekurongedza harina kurongeka. Nyatsoteerera nyaya dziri pamusoro apa paunenge uchitenga dota remafuru kuti uve nechokwadi chekuti unogona kutenga dota remafuru remhando yepamusoro.

(2) Ungatora sei sampuro yekugamuchira?
Chinja nzira yechinyakare yekutora sampuli nenzvimbo, ndiko kuti, sanganisa pombi yakakosha yekutora sampuli papombi yesimbi inodyisa ash ine dhayamita ye100mm pakukwirira kwakamira kweinenge 1.5 metres kubva pasi, iyo inogona kusarudzwa zvisina kurongeka chero nguva panguva yekuburitsa ash. Tora sampuli uye uzivise pachena mutengesi weash ash kuti kana mhedzisiro yesampuli mbiri idzi ikawanikwa yakasiyana mumotokari imwe chete, vacharangwa zvakanyanya.
