Ukusebenzisa i-biomass okuxekethile ukukhiqiza uphethiloli we-pellet ekamelweni lokushisa kuyindlela elula neqondile yokusebenzisa amandla e-biomass. Ake sixoxe nawe ngobuchwepheshe bokwenza ama-straw straw pellets.

Ngemuva kokuthi impahla ye-biomass enesakhiwo esixekethile kanye nokuminyana okuphansi ingaphansi kwamandla angaphandle, impahla eluhlaza izobhekana nezigaba zokuhlela kabusha, ukuguqulwa komshini, ukuguquguquka kwe-elastic kanye ne-plastic deformation. Ama-molecule e-inelastic noma i-viscoelastic cellulose ahlanganiswe futhi asontekile, Umthamo wezinto ezibonakalayo uyancipha futhi ukuminyana kuyanda.

Isilinganiso sokucindezelwa sendandatho efayo semishini ye-biomass pellet sinquma usayizi wengcindezi yokubumba. Okuqukethwe kwe-cellulose kwezinto zokusetshenziswa okufana nezihlanga zommbila nomhlanga kuncane, futhi kulula ukuwohloka lapho kukhishwe amandla angaphandle, ngakho isilinganiso sokucindezelwa kwendandatho edingekayo ekubunjweni sincane. , okungukuthi, ingcindezi yokubumba incane. Okuqukethwe kwe-cellulose ye-sawdust kuphezulu, futhi isilinganiso sokucindezelwa kwe-ring ring edingekayo ekubunjweni sikhulu, okungukuthi, ingcindezi yokubumba inkulu. Ngakho-ke, i-biomass eluhlaza isetshenziselwa ukukhiqiza uphethiloli we-pellet obunjiwe, futhi ukucindezela kwe-ring kufa okuhlukile kufanele kusetshenziswe. Ngezinto ze-biomass ezinokuqukethwe kwe-cellulose okufanayo ezintweni ezingavuthiwe, indandatho ifa enesilinganiso esifanayo sokucindezela ingasetshenziswa. Kulezi zinto ezisetshenziswayo ezishiwo ngenhla, njengoba isilinganiso sokucindezela sokufa kwendandatho sikhula, ukuminyana kwezinhlayiyana kuyanda, ukusetshenziswa kwamandla kuyanda, futhi okukhiphayo kuyanda. Lapho isilinganiso esithile sokucindezela sifinyelelwa, ukuminyana kwezinhlayiya ezakhiwe kukhula kancane, ukusetshenziswa kwamandla kuyanda ngokufanele, kodwa okukhiphayo kuncipha. I-ring die ene-compression ratio engu-4.5 isetshenziswa. Nge-sawdust njengempahla eluhlaza kanye nendandatho efa enesilinganiso sokucindezela esingu-5.0, ukuminyana kukaphethiloli we-pellet kungahlangabezana nezidingo zekhwalithi, futhi ukusetshenziswa kwamandla kwesistimu yemishini kuphansi.

Impahla efanayo eluhlaza yakhiwa ku-ring die enezilinganiso ezihlukene zokucindezelwa, ukuminyana kukaphethiloli we-pellet kukhula kancane kancane ngokwanda kwesilinganiso sokucindezela, futhi ngaphakathi kohlu oluthile lwesilinganiso sokucindezela, ukuminyana kuhlala kuzinzile, lapho isilinganiso sokucindezela sikhuphuka sibe yi-compression ratio. ngezinga elithile, Impahla eluhlaza ngeke ikwazi ukwakheka ngenxa yokucindezela okukhulu. Usayizi wokusanhlamvu we-rice husk mkhulu futhi okuqukethwe komlotha kukhulu, ngakho-ke kunzima ukuthi i-rice husk yakhe izinhlayiya. Okokusebenza okufanayo, ukuze kutholwe ukuminyana kwezinhlayiyana ezinkudlwana, kufanele kuklanywe kusetshenziswa isilinganiso sokuminyaniswa kwemodi yendandatho Enkulu.
Umthelela wosayizi wezinhlayiyana zezinto ezingavuthiwe ezimeni zokubumba

Ubukhulu bezinhlayiyana zezinto zokusetshenziswa ze-biomass zinethonya elikhulu ezimweni zokubumba. Ngokukhula kosayizi wezinhlayiyana zohlanga lommbila nezinto zokusetshenziswa zomhlanga, ukuminyana kwezinhlayiya ezibunjwayo kuncipha kancane kancane. Uma usayizi wezinhlayiyana wempahla eluhlaza mncane kakhulu, izophinde ithinte ukuminyana kwezinhlayiyana. Ngakho-ke, lapho usebenzisa i-biomass efana neziqu zommbila nomhlanga njengezinto zokusetshenziswa zokukhiqiza uphethiloli wezinhlayiyana, kufanelekile kakhulu ukugcina usayizi wezinhlayiyana ku-1-5 nun.

Umthelela womswakamo esitokisini sokudla ngokuminyana kukaphethiloli we-pellet

Kukhona inani elifanele lamanzi abophekile namanzi amahhala emzimbeni webhayoloji, onomsebenzi wokuthambisa, onciphisa ukungqubuzana kwangaphakathi phakathi kwezinhlayiya futhi uthuthukise uketshezi, ngaleyo ndlela kuthuthukiswe ukushelela nokufakwa kwezinhlayiya ngaphansi kwesenzo sokucindezela. . Lapho okuqukethwe kwamanzi ezinto zokusetshenziswa ze-biomass Lapho umswakama uphansi kakhulu, izinhlayiya azikwazi ukunwetshwa ngokugcwele, futhi izinhlayiya ezizungezile azihlanganisiwe ngokuqinile, ngakho azikwazi ukwakheka. Lapho umswakama uphezulu kakhulu, nakuba izinhlayiya zinganwetshwa ngokugcwele ekuqondeni kwe-perpendicular kuya ekucindezelekeni okukhulu okuyinhloko, futhi izinhlayiya zingakwazi ukuhlangana nomunye nomunye, kodwa Njengoba amanzi amaningi kumpahla eluhlaza akhishwa futhi asakazwa phakathi kwezingqimba zezinhlayiya. , izingqimba zezinhlayiya azikwazi ukunamathela eduze, ngakho azikwazi ukwakhiwa.

Ngakho-ke, lapho imishini ye-biomass pellet kanye nemishini isebenzisa i-biomass efana neziqu zommbila nomhlanga njengempahla yokukhiqiza uphethiloli we-pellet, umswakama wezinto zokusetshenziswa kufanele ugcinwe ku-12% -18%.

Ngaphansi kwezimo zokushisa ezijwayelekile, ngesikhathi sokubunjwa kwenqubo yokucindezelwa kwezinto zokusetshenziswa kwe-biomass, izinhlayiya zikhubazekile futhi zihlanganiswe ngendlela ye-mutual meshing, futhi izingqimba zezinhlayiyana zihlanganiswa ngendlela yokuhlanganisana. Okuqukethwe kwe-cellulose ezintweni ezingavuthiwe kunquma ubunzima bokubumba Ukuphakama kokuqukethwe kwe-cellulose, ukubumba kulula. Ubukhulu bezinhlayiyana kanye nomswakama wezinto zokusetshenziswa kunomthelela omkhulu ezimeni zokubumba.
