Umatshini we-pellet wokufa we-ring sisixhobo esiphambili senkqubo yokuvelisa i-biomass fuel pellet, kunye nokufa kweringi yinxalenye engundoqo yomatshini wepellet yokufa kweringi, kwaye ikwayenye yezona ndawo zinxitywa ngokulula kwi-ring straw. umatshini wepellet. Funda izizathu zokusilela kufa kweringi, uphucule iimeko zokusetyenziswa komsesane wokufa, uphucule umgangatho wemveliso kunye nemveliso, ukunciphisa ukusetyenziswa kwamandla (i-akhawunti yokusetyenziswa kwegranulation ye-30% ukuya kwi-35% yokusetyenziswa kwamandla kuyo yonke iworkshop), kunye nokunciphisa imveliso. iindleko (i-ring die loss enye Ixabiso leprojekthi libalelwa ngaphezu kwe-25% ukuya kwi-30% yeendleko zokuhombisa yonke iworkshop yemveliso) kwaye inefuthe elikhulu.

1. Umgaqo osebenzayo womatshini wepellet wokufa weringi

Umsesane wokufa uqhutywa ukuba ujikelezwe yimoto ngokusebenzisa isinciphisi. I-roller ecinezelayo efakwe kwi-ring ring ayiguquki, kodwa ijikeleza ngokwayo ngenxa ye-friction kunye ne-ring ejikelezayo yokufa (ngokudibanisa izinto). Izinto ezicinyiweyo kunye nezifudumalayo ezingena kwigumbi elicinezelayo zisasazwa ngokulinganayo phakathi kwee-roller ezicinezelayo nge-spreader, zixinzelelwe kwaye zixinzelelwe ngama-roller acinezelayo, kwaye ngokuqhubekayo zikhutshwe ngomngxuma wokufa wendandatho yokufa ukuze zenze amaqhekeza e-columnar kwaye ulandele i-ring ring. Iringi ijikeleziswa, kwaye i-granular biomass fuel particles yobude obuthile inqunywe ngumsiki ofakwe ngokusisigxina ngaphandle kwendandatho yokufa. Isantya somgca we-ring die kunye ne-nip roll iyafana nakweyiphi na indawo yoqhagamshelwano, kwaye yonke ingcinezelo yayo isetyenziselwa i-pelletizing. Kwinkqubo yokusebenza eqhelekileyo ye-ring die, kusoloko kukho ukungqubana phakathi kweringi yokufa kunye nezinto eziphathekayo. Njengoko umthamo wezinto eziveliswayo usanda, iringi iyafa ngokuthe ngcembe kwaye ekugqibeleni iyasilela. Eli phepha lijonge ukuhlalutya ukusilela okubangela ukufa kweringi, ukuze kwenziwe iingcebiso malunga nokuveliswa kunye nokusetyenziswa kweemeko zokufa kweringi.

2. Uhlalutyo lwezizathu zokungaphumeleli zokufa kweringi

Ngokombono weyona nto ingaphumeleliyo yokufa kweringi, inokwahlulwa ibe ngamacandelo amathathu. Uhlobo lokuqala: Emva kokuba i-ring ring isebenze ixesha elide, udonga lwangaphakathi lomngxuma ngamnye omncinci wezinto eziphathekayo luphelile, ububanzi bomngxuma buyanda, kwaye i-particle diameter ye-granular biomass fuel eveliswayo idlula ixabiso elichaziweyo kwaye liyasilela; uhlobo lwesibini: Emva kokuba udonga lwangaphakathi lwendandatho lufa, ubuso obungaphakathi Ukungalingani kunzulu, okuthintela ukuhamba kweengqungquthela ze-biomass fuel, kwaye umthamo wokukhupha uyancipha kwaye uyeke ukusebenzisa; uhlobo lwesithathu: emva kokuba udonga lwangaphakathi lwendandatho yokufa lugugile, ububanzi bangaphakathi buyanda kwaye ubukhulu bodonga buyancipha, kwaye udonga lwangaphakathi lomngxuma wokukhupha lunxibe kunye nokugqoka. , ukwenzela ukuba ubukhulu bodonga phakathi kwemingxuma yokukhupha iyancipha ngokuqhubekayo, ngoko amandla okwakhiwa ayancipha. Ngaphambi kokuba ububanzi bemingxuma yokukhupha bunyuke ukuya kwixabiso elivumelekileyo elichaziweyo (oko kukuthi, phambi kokuba uhlobo lokuqala lwenzeka yokusilela), kwezona ziNgcaka ziyingozi kakhulu zavela kuqala kwicandelo elinqamlezileyo kwaye zaqhubeka zisanda de iintanda zandiswa ukuya kwindawo enkulu. uluhlu kunye nokufa kweringi akuphumelelanga. Oonobangela ababalulekileyo bezi ziganeko zintathu zokusilela zinokushwankathelwa njengokunxitywa kwe-abrasive kuqala, kulandele ukusilela kokudinwa.

2-1 Ukunxiba kwe-Abrasive

Kukho izizathu ezininzi zokugqoka, ezahlulahlulwe zibe yimpahla eqhelekileyo kunye neengubo ezingaqhelekanga. Izizathu eziphambili zokugqoka okuqhelekileyo ziyifomula yezinto eziphathekayo, ubungakanani beqhekeza elincinciweyo, kunye nokucima kunye nomgangatho wokushisa we powder. Phantsi kweemeko eziqhelekileyo zokunxiba, umsesane wokufa uya kunxitywa ngokufanayo kwicala le-axial, okukhokelela kumngxuma wokufa omkhulu kunye nobukhulu obuncinci bodonga. Izizathu eziphambili zokugqoka okungaqhelekanga zi: i-roller yoxinzelelo ilungelelaniswe ngokuqinileyo, kwaye i-gap phakathi kwe-roller kunye ne-ring ring incinci, kwaye banxibe; i-angle ye-spreader ayilungile, okubangela ukusabalalisa okungalinganiyo kwezixhobo kunye nokugqoka okuyingxenye; intsimbi iwela kwidiyizi kwaye inxibe. Kule meko, i-ring die die idla ngokunxitywa ngokungaqhelekanga, ubukhulu becala ngokumila kwegubu esinqeni.

Ubungakanani bamasuntswana ekrwada Imathiriyeli ekrwada yokucolwa kokucolwa kufuneka ibephakathi kwaye ifane, kuba imathiriyeli ekrwada yokucolwa kokucolwa kwayo imisela indawo yomphezulu eyenziwe ngamasuntswana e-biomass fuel. Ukuba ubungakanani be-particle ye-raw material i-coarse kakhulu, ukunxiba kwefa kuya kwandiswa, imveliso iya kuhla, kwaye ukusetyenziswa kwamandla kuya kwandiswa. Ngokuqhelekileyo kufuneka ukuba izinto eziluhlaza kufuneka zidlule kwindawo ye-sieve ye-8-mesh emva kokutyunyuzwa, kunye nomxholo kwi-sieve ye-25-mesh akufanele idlule i-35%. Kwizinto ezinomxholo ophezulu wefiber ekrwada, ukongeza inani elithile legrisi kunokunciphisa ukungqubana phakathi kwezinto kunye nomsesane wokufa ngexesha lenkqubo yegranulation, enenzuzo yokuba izinto zidlule kumsesane wokufa, kwaye iipellets zinembonakalo egudileyo. emva kokwenza. Umsesane wokufa umatshini wepellet

Ungcoliseko lwemathiriyeli ekrwada: Ubuninzi besanti kunye nokungcola kwentsimbi kwizinto eziphathekayo kuya kukhawulezisa ukuguga kwefa. Ngoko ke, ukucocwa kwezinto eziluhlaza kubaluleke kakhulu. Okwangoku, uninzi lwezityalo ze-pellet ze-biomass zihlawula ingqalelo ngakumbi ekususweni kokungcola kwentsimbi kwizinto eziluhlaza, kuba izinto zentsimbi ziya kubangela umonakalo onamandla kwi-press mold, i-roller ye-press kunye nezixhobo. Nangona kunjalo, akukho ngqalelo ehlawulwayo ekususweni kwesanti kunye nokungcola kwegrabile. Oku kufuneka kuvuse ingqalelo yabasebenzisi bomatshini wepellet wokufa weringi
