nkhani

Sodium sulfide ndi mtundu wa zinthu mankhwala, kutchula umagwirira, timaganiza za kuyesera mankhwala, mu kuyesera popanda chida ndi fyuluta, kwenikweni kwa fyuluta, anthu ambiri anaona zazing'ono pa sukulu, ife wamba yaing'ono fyuluta m'kalasi umagwirira, koma ntchito. mu mankhwala chomera zambiri lalikulu fyuluta chida, tiyeni tiwone chimene fyuluta chida.

Kusefera ndi mtundu wa ntchito yolekanitsa tinthu tating'ono tomwe timayimitsidwa mumadzi kapena gasi. Zida zambiri zimagwiritsidwa ntchito posefera. Apa, zida zingapo zomwe zimagwiritsidwa ntchito nthawi zambiri zimayambitsidwa pano, kuti ziwonetsedwe kwa opanga okha.

(1) Zosefera za chubu

Amapangidwa ndi porous filter chubu, yosavuta kutchinjiriza ndi kusefera, ndipo amagwiritsidwa ntchito kuyeretsa zonyansa zabwino kwambiri mu filtrate, monga capacitor borax, barium carbonate, ndi zina zambiri.

(2) Miyendo itatu yapakati

Kupanga mankhwala. Osalala ntchito, footprint yaing'ono, zosavuta kulamulira kulekana ndi nthawi kusamba, koma mkombero yaitali kusefera, mphamvu yaing'ono kupanga, mkulu ntchito mwamphamvu. Pakuti crystalline kulekana kwa mchere mchere, monga mkuwa sulphate, sodium erysalum, etc.

(3) Taper-mtundu wopitilira centrifuge

Mankhwala opangidwa, kusefera kosalekeza, kutsitsa, kapangidwe kosavuta, kukonza kosavuta, koma kutsuka sikwabwino, slurry yaing'ono yolimba yaing'ono, kutayikira kwakukulu, yoyenera kulekanitsa particles zazikulu yunifolomu crystallization, monga borax.

(4) Spiral kutsitsa kukhazikikako centrifuge

Kusefedwa kosalekeza, keke ya fyuluta ikhoza kutsukidwa, fyuluta ili ndi 1-7%, yoyenera kulekanitsa kusintha kwakukulu, kusiyana kwakukulu kwa kuyimitsidwa, pali ofukula ndi yopingasa. Kwa kusefera kwa calcium carbonate ndi nickel sulfate.

Zitha kuwoneka kuti pali zida zambiri zosefera, koma zamitundu yosiyanasiyana ya zida zosefera, ndi sodium sulfide yathu imafunikiranso chida chotere pakuyesa. Ngati mukufuna kapena mukufuna sodium sulfide, mutha kulumikizana nafe, tidzakupatsirani zinthu zabwino kwambiri, zomwe zingakupangitseni kukhutitsidwa.
