STET m'Galimoto olekanitsa

Koperani

cha ku Switzerland Zida & Technology LLC ndi (STET) Triboelectrostatic lamba olekanitsa (chithunzi 1) ali anasonyeza imapanga pokonza particles zabwino 1995 kulekanitsa Unburned mpweya kuchokera mchere ntchentche phulusa zomera malasha amapanga mphamvu North America, Europe ndi Asia kuti apange kalasi ya konkriti Pozzolan kuti agwiritse ntchito ngati cholowa m'malo mwa simenti. 1 Kudzera woyendetsa chomera kuyezetsa, mu-chomera ntchito chionetsero ndi / kapena ntchito malonda, olekanitsa STET wasonyeza Kupindula mchere ambiri kuphatikizapo potashi, barite, calcite, ndipo talc.2

Popeza chidwi kwambiri mu njira imeneyi wakhala mphamvu yake pokonza tinthu zosakwana 0.1 mamilimita, malire a ochiritsira chatsika ndi ng'oma mpukutu separators, chapamwamba tinthu kukula malire a STET a kamangidwe panopa sipanatenge ndi cholinga cha chitukuko cha sayansi m'mbuyomu. Komabe, khama liwakhalira njira kuonjezera izo ndi kusintha kapangidwe. STET panopa manufactures zamitundu iwiri ndi ubongo mwadzina la 40 ndi 23 chinkafunika tonne paola.

chithunzi 1: cha ku Switzerland Zida & Technology wa Triboelectric m'Galimoto olekanitsa

mfundo za ntchito ya olekanitsa STET ali taphunzira Ziwerengero 2 & 3. particles ndi mlandu ndi zotsatira triboelectric kudzera tinthu ndi tinthu mwansanga mu mlengalenga Wopanda chakudya wogulitsa ndi mkati kusiyana maelekitirodi ndi. The ntchito voteji pa maelekitirodi ndi pakati ± 4 ± 10kV wachibale pansi, kupereka okwana voteji kusiyana kwa 8 kuti 20 kV. lamba, umene unapangidwa pulasitiki si kuchititsa, ndi mauna lalikulu ndi za 60% oonekera. particles mosavuta kudutsa ming'alu lamba.

chithunzi 2: Chojambula wa STET olekanitsa

Mayendedwe oyenda ndi kukhudzana kwa tinthu tating'onoting'ono mkati mwa kusiyana kwa electrode komwe kumakhazikitsidwa ndi lamba wosuntha ndikofunikira pakuchita bwino kwa olekanitsa.. Pa yolowera kusiyana maelekitirodi ndi particles zoipa mlandu amakopeka ndi mphamvu ya magetsi kumunda kwa maelekitirodi pansi HIV. The particles ndithu mlandu amakopeka ndi zoipa mlandu elekitirodi pamwamba. Liwiro la mosalekeza lamba kuzungulira ndi variable ku 4 kuti 20 Ms. Ma geometry a lamba wodutsa njira zolumikizira zimasesa tinthu tating'onoting'ono ta maelekitirodi kuwasunthira kumapeto kwa cholekanitsa ndikubwerera kumalo ometa ubweya wapamwamba pakati pa magawo osuntha a lamba.. Chifukwa tinthu chiwerengero kachulukidwe ndi mkulu mkati kusiyana maelekitirodi ndi (pafupifupi gawo limodzi mwa magawo atatu a voliyumuyo amakhala ndi tinthu tating'onoting'ono) ndi nthenda yotaya ndi mwamphamvu mwakwiya, pali ngozi zambiri pakati pa particles ndi mulingo woyenera adzapereke zimachitika mosalekeza mu zone kulekana. Kuthamanga kwanthawi yayitali kochititsidwa ndi magawo a lamba wosuntha mosagwirizana ndi kulipiritsanso ndikusiyanitsidwa mosalekeza kumapangitsa kuti pakhale kusiyana kopitilira muyeso mkati mwa chipangizo chimodzi.. Izi mosalekeza kulipiritsa ndi recharging particles mkati olekanitsa kuthetsa kufunika kwa dongosolo lililonse "charger" isanayambe kubweretsa zinthu kwa olekanitsa., Motero kuchotsa mavuto pa mphamvu kulekana electrostatic. The linanena bungwe la olekanitsa izi ndi mitsinje awiri, ndi kuganizira, ndi zotsalira, popanda middlings mtsinje. Mwachangu wa olekanitsa izi wasonyeza ofanana ndi pafupifupi atatu magawo a chatsika kulekana ndi middlings akonzanso.

chithunzi 3: Elekitirodi Kusiyana kwa STET m'Galimoto olekanitsa

The STET olekanitsa ali zambiri ndondomeko zosintha kuti athe kukhathamiritsa malonda-off pakati mankhwala chiyero ndi kuchira amene ali chibadidwe ndondomeko iliyonse Beneficiation.. The kusintha coarse ndi doko chakudya kudzera zomwe chakudya umayamba m'chipinda kulekana. Doko furthest kuchokera kumaliseche hopper chipatso anakhumba amapereka kalasi bwino koma likuvutika ayambe m'munsi. A kusintha bwino ndi liwiro lamba. Kusiyana elekitirodi, lomwe ndi chosinthika pakati 9 ndi 18 mamilimita, ndi voteji ntchito (± 4 ± 10 kV) nawonso zosintha zofunika. The polarity wa maelekitirodi mwina tidzasandulika amene zothandizira kulekana kwa ena zipangizo. Pretreatment zakuthupi chakudya ndi mphamvu yeniyeni zili kufufuza chinyezi (monga anayeza ndi chakudya wachibale chinyezi) Nkofunika iyende akadakwanitsira kulekana. Kuwonjezera kufufuza ndalama ya wothandizila mankhwala mlandu-kusintha angathe kukathandiza optimizing ndondomeko.

Monga tanenera, Kugwiritsa ntchito koyamba kwa malonda a cholekanitsa lamba kwakhala kulekanitsa chala cha malasha kuchokera ku mchere wagalasi wa Aluminosilicate kuchokera ku phulusa la ntchentche kuchokera kumalo opangira magetsi.. Njira imeneyi ndi wapadera pakati separators electrostatic mu mphamvu yake kupatukana ntchentche phulusa, amene ambiri ali zikutanthauza tinthu kukula zosakwana 0.02 mamilimita. The STET olekanitsa nayenso zatsimikiziridwa mosavuta osiyana magnesite ku talc, halite ku kieserite ndi sylvite, silicates ku Bart, ndi silicates kuchokera ku calcite.3 The mean particle size of all of these feed materials has been in range of 0.02 ndipo 0.1mm. Zitsanzo za kusiyana kwa zipangizo zingapo aphatikizidwa Table 1.

Table 1 - Chitsanzo amapatukana

kupatukana	chakudya	mankhwala	Kusangalala
kashiamu carbonate - Silicates	9.5% acid Insols	<1% A.I.	89% CaCO3
Talc - Magnesite	58% talc	95% talc	77% talc
		88% talc	82% talc
Kierserite + KCl - NaCl	11.5% K2O	27.1% K2O	90% K2O
	12.2% kieserite	31.8% kieserite	94% kieserite
	64.3% NaCl	14.3% NaCl	92% NaCl kukana
Kuwuluka Ash Maminolo - mpweya	6.3% mpweya	1.8% mpweya	88% mchere
	11.2% mpweya	2.1% mpweya	84% mchere
	19.3% mpweya	2.9% mpweya	78% mchere

chiphunzitso, kuyambira tinthu adzapereke kumadalira mmene triboelectric, mchere ziwiri kuti amamasulidwa Chrixitu (kondakitala- wochititsa kapena nonconductor-wochititsa) akhoza anapambulwa njira imeneyi. kuthekera ntchito zina monga magnesite-khwatsi, feldspar-khwatsi, mchenga mchere, ena amapatukana potashi mchere, ndi
Kulekanitsidwa kwa mankwala-calcite-silika.
