Pelletizing muyezo wa biomass wood pellet makina zida

1. Utuchi wophwanyika: utuchi wa utuchi wokhala ndi macheka. Ma pellets opangidwa amakhala ndi zokolola zokhazikika, ma pellets osalala, kuuma kwakukulu komanso kugwiritsa ntchito mphamvu zochepa.

2. Miyendo yaying'ono mu fakitale ya mipando: Chifukwa kukula kwa tinthu ndi kwakukulu, zinthu sizili zophweka kulowa mu mphero ya nkhuni, choncho n'zosavuta kuletsa mphero ya pellet ndipo zotsatira zake zimakhala zochepa. Komabe, zometa zing'onozing'ono zimatha kukhala granulated pambuyo pophwanyidwa. Ngati palibe chikhalidwe chophwanyika, 70% tchipisi tamatabwa ndi 30% zometa zazing'ono zitha kusakanikirana kuti zigwiritsidwe ntchito. Zometa zazikulu ziyenera kuphwanyidwa musanagwiritse ntchito.

3. Mchenga wopukutira ufa m'mafakitale a bolodi ndi mafakitale amipando: mphamvu yokoka ya mchenga wopukutira ufa ndi wopepuka, sikophweka kulowa mu granulator, ndipo n'zosavuta kuletsa granulator, zomwe zimapangitsa kutulutsa kochepa; chifukwa cha kuwala enieni mphamvu yokoka mchenga kupukuta ufa, Ndi bwino kusakaniza tchipisi nkhuni ndi granulate pamodzi. Aliyense angawerenge pafupifupi 50% kuti akwaniritse granulation.

4. Zotsalira za matabwa ndi tchipisi ta matabwa: Zotsalira za matabwa ndi tchipisi tamatabwa zingagwiritsidwe ntchito pokhapokha ataphwanyidwa. Ndi bwino pulverize tinthu kukula kufika utuchi tinthu chitsanzo anacheka ndi gulu macheka, ntchito mkulu-liwiro pulverizer, ntchito chip 4mm, tinthu linanena bungwe ndi khola, tinthu ndi yosalala, kuuma ndi mkulu, ndi kugwiritsa ntchito mphamvu kumakhala kochepa.

5. Zopangirazo zakhala mildewed: mtundu wasanduka wakuda, dothi lokhala ngati dothi limakhala ndi mildew, ndipo silingaunikizidwe kukhala zopangira zoyenerera. Pambuyo pa mildew, cellulose mu tchipisi tamatabwa amawola ndi tizilombo toyambitsa matenda ndipo sangathe kukanikizidwa kukhala tinthu tating'onoting'ono. Ngati iyenera kugwiritsidwa ntchito, tikulimbikitsidwa kuwonjezera tchipisi tamatabwa tatsopano toposa 50% ndikusakaniza. Apo ayi, sichingapanikizidwe mu pellets oyenerera.

6. Zinthu za Fibrous: Kutalika kwa ulusi uyenera kuyendetsedwa pamtundu wa fiber. Nthawi zambiri, kutalika sikuyenera kupitirira 5mm. Ngati ulusiwo uli wautali kwambiri, umatsekereza njira yodyetsera mosavuta ndikuwotcha injini ya chakudya. Kwa zipangizo za fibrous, kutalika kwa ulusi kuyenera kuyendetsedwa. Nthawi zambiri, kutalika sikuyenera kupitirira 5mm. Njira yothetsera vutoli ndikusakaniza pafupifupi 50% ya tchipisi ta nkhuni kuti apange, zomwe zingalepheretse njira yodyetsera kuti isatseke. Kaya ndalama zomwe zawonjezeredwa, muyenera kuyang'ana nthawi zonse ngati dongosolo latsekedwa. vuto, kuteteza kuchitika kwa zolakwika monga kuyaka ndi kuwononga galimoto ya chakudya.
