Matanho ekurapa
Chekutanga, sarufa inopwanyika kuita upfu, yotumirwa muchoto chinopfuta nemhepo yakamanikidzwa yekupisa pa600 ~ 800 ℃. Kuwanda kwemhepo yakawedzerwa inenge 2 nguva yehuwandu hwezvinyorwa, uye huwandu hwegesi SO2 ndeye 10-13.
Chechipiri, mushure mekutonhora, kubviswa kweguruva uye kusefa, iyo sublimated sulfur uye zvimwe zvitsvina zvinobviswa, uye tembiricha yegesi inoderedzwa kusvika pa 0 ℃, uye inopfuudzwa mune inoteedzana reactor.
Yechitatu nhanho reactor inowedzerwa zvishoma nezvishoma naamai doro uye soda soda mhinduro ye neutralization reaction, maitiro ekuita ndeaya anotevera:
2NaHSO4+ Na2CO3 -- 2Na2SO4 + CO2+ H2O
Iyo inoguma sodium sulfite kumiswa inotevedzana kupfuura yechipiri nhanho uye yekutanga nhanho reactor yekunyura kuita neSO2 kugadzira iyo crystallization yesodium metabisulfite.

Kudzora kweinjiniya: nzira yekugadzira yakavharwa, uye kufefetera kunosimbiswa.
Kudzivirirwa kwechirongwa chekufema: kana guruva remumhepo richidarika mwero, unofanirwa kupfeka guruva rekuzvidzivirira refirita mask.Muchiitiko chekununurwa kwekukurumidzira kana kubuda, mweya wekufema unofanirwa kupfekwa.
Precautions for Operation
Kuvharwa kushanda kusimbisa mhepo.Vashandi vanofanira kunge vakanyatsodzidziswa uye kunyatsotevera maitiro ekushanda.Vashandi vanokurudzirwa kupfeka-self-suction filter dust masks, kupfeka kemikari yekuchengetedza magirazi ekudzivirira, kupfeka anti-chepfu permeation hovhorosi, uye kupfeka magirovhosi erabha.Dzivisa guruva.Dzivisa kusangana neoxidants uye acids.Bata zvishoma kuti udzivise kukuvadzwa kwechimbichimbi leakamp. midziyo inogona kuchengetedza zvinhu zvinokuvadza.
Kuchengetedza: Shading, yakavharwa kuchengetedza.
Inofanira kuchengetwa munzvimbo inotonhorera, yakaoma.Iyo pasuru inofanira kuvharwa kudzivirira mhepo oxidation.Chenjerera pakunyorova.Kutakurwa kunofanirwa kuchengetedzwa kubva kumvura nechiedza chezuva.Zvinorambidzwa zvachose kuchengeta uye kutakura neacids, oxidants uye zvinokuvadza uye zvine chepfu zvinhu.Ichi chigadzirwa hachina kukodzera kuchengetwa kwenguva refu.Bata nehanya panguva yekurodha uye kuburitsa mvura kubva pakupwanya uye kudzivirira moto wakasiyana-siyana. zvekudzimisa moto kuti zvidzime.
Zvekutakura zvinhu
Kutakura kunofanira kunge kwakazara uye kutakurwa kunofanira kunge kwakachengeteka panguva yekutakura.Iva nechokwadi chokuti chigadziko chacho hachibvi, kudonha, kudonha kana kukanganisa panguva yekufambisa.Inorambidzwa zvachose kusanganiswa neoxidants, acids uye mishonga inodyika.Kutakura kunofanira kuchengetedzwa kubva kune zuva, mvura uye kupisa kwakanyanya.Motokari inofanira kunyatsocheneswa mushure mekutakura.
