cha ku Switzerland Zida & Technology LLC (STET) zachitika buku, patenti electrostatic lamba olekanitsa kuti wasonyeza pa malonda-ang'ono mu processing mchere mafakitale ndi yobwezeretsanso wa malasha kuyaka ntchentche phulusa.
Electrostatic luso kulekana wakhala anaphunzira pa 100 zaka. Pamenepo, woyamba setifiketi ntchito chakudya olekanitsa electrostatic wa middlings tirigu anali ada mangala ku 1880. kafukufuku sikumatha ndi luso limasonyeza lonjezo polenga kufunika kwa zinyalala mtsinje byproducts njira panopa yopanga, monga kupanga mbewu mafuta kapena nyama (kuphatikizapo nsomba) processing.
Mwachidule, ndi STET olekanitsa ntchito potengera kusiyana umagwirira pamwamba. Nthawi zina, Kulekanitsidwa izi sizikanakhala zotheka kugwiritsa ntchito tinthu kukula kapena osalimba nokha. separators STET titenge mwayi wa "Tribo-adzapereke" (Onani Chithunzi 1) amene amapezeka mofulumira mwa zida.
chithunzi 2 chikusonyeza mmene particles odyetsedwa ndi limodzi mwa madoko angapo chakudya mu zone kulekana, ndilo kusiyana maelekitirodi yopingasa (< 13mamilimita [0.5"]). Voteji (amangoona 12kV) umagwiritsidwa kudutsa kusiyana izi yopapatiza kulenga amphamvu munda magetsi. Tinthu imakhudzidwa kudzera zone izi kulekana ndi kampani mosalekeza kuzungulira, lotseguka mauna lamba zikugwira ntchito pa liwilo (4-20Ms [13-65Ft / s]).
Mkati zone kulekana, kamangidwe kampani ya mofulumira kusuntha lamba mosalekeza amagwira ntchito zingapo nthawi imodzi (chithunzi 3).
Iwo amalenga mkulu kugwedezekagwedezeka zone pakati maelekitirodi ndi, kulimbikitsa tribo-adzapereke. Izi zimachititsa ku mobwerezabwereza mwansanga tinthu ndi tinthu, kusunga zipangizo mlandu mkati olekanitsa ndi kuchotsa kufunika kwa kunja chisanadze nawuza dongosolo. Pomaliza, kayendedwe ka lamba chikusesa particles zabwino maelekitirodi, kukhalabe ntchito yawo, ndi facilitates mankhwala osiyana ndi chochokera zosonkhanitsira.
The STET tribo-electrostatic lamba olekanitsa wasonyeza luso la "beneficiate" (Kuonjezera katundu wa) zosiyanasiyana mchere ndi kuuluka phulusa padziko lonse waonetsa ntchito kwa processing wa ambiri zipangizo chakudya ndi chakudya.
Chitsanzo chimodzi cha izi ndi processing wa Whitefish Chakudya umene malonda analandira, milled, ndi kuyesedwa kudzera wathu olekanitsa woyendetsa-ang'ono zinkaimira Chithunzi 4.
zotsatira
mayesero woyendetsa anali kuchitidwa pa 2 tonnes wa malonda anapeza Whitefish Chakudya anali milled isanafike processing kudzera tribo-electrostatic wathu olekanitsa. Zotsatira Whitefish Chakudya amasonyeza mapuloteni patsogolo ndi kuchepetsa kwambiri wa phulusa mu chiphaso limodzi, monga tikuonera apa.
| Zotsatira za chomera choyendetsa | |||
|---|---|---|---|
| chakudya | E1 | E2 | |
| Zokolola zambiri | 39.3% | 60.7% | |
| Chinyezi | 2.5% | ||
| ash | 12% | 6.1% | 15.2% |
| mapuloteni | 81.1% | 89.8% | 77.6% |
The zambiri pa tsamba lotsatirali anafotokoza mankhwala kalasi (monga m'mbuyo-ncho ndi mapuloteni wt. %) kuti zokolola misa.
Iwo Tingaone pazimene izi kuti pali malonda kuchokera pakati pa magawo awiri. Komabe, tinatha kukwaniritsa 10% (wachibale) kuwonjezera mapuloteni ndi pafupifupi kwambiri 50% kuchepetsa phulusa mu mtsinje mankhwala mu chiphaso limodzi, ndipo popanda kukhathamiritsa zina.
Chakudya chuma tinthu kukula anali kusintha ndi processing mu hammermill kuti kukula asonyezedwa pa tsamba lotsatira.
Odzipatula a STET amatha kugwiritsa ntchito ambiri chakudya ndi zakudya za pafupi 10-15 MT paola (malingana kachulukidwe) koma zimawononga okha 3-4 kWh magetsi. ndondomeko zimathandiza kusiyana ndi madzi ndi mankhwala ufulu, ndi kulibe athandizira matenthedwe ndi palibe mtsinje zinyalala kwaiye.
Njira kulekana kungachititse yopanga buku mkulu, mkulu khalidwe nsomba mapuloteni monga pophika mu formulations chakudya kuchokera zinyalala nsomba processing.
Izi chochokera kwa processing nsomba limasonyeza lonjezo popereka zakudya zomanga thupi wapatali ndi mchere mnzake kapena malonda nyama, kuthandiza kuthandiza Kowonjezereka kwa zakudya zomanga thupi lotengeka ndi kuchuluka kwa anthu.
