Manyolo a manyolo a kolobe

Ho boetse ho na le mapolasi a mangata a maholo le a manyenyane.Ha li ntse li finyella litlhoko tsa batho tsa nama, li boetse li hlahisa bongata bo boholo ba liphoofolo tse ruiloeng le tsa likhoho.Kalafo e utloahalang ea manyolo e ke ke ea rarolla feela bothata ba tšilafalo ea tikoloho ka katleho, empa hape e fetola litšila.Weibao e hlahisa melemo e mengata 'me ka nako e ts'oanang e theha tikoloho e tloaelehileng ea temo.

Manyolo a lintho tse phelang a tsoa haholo limela le/kapa liphoofolo, 'me a lomositsoe, 'me a bolile a na le lintho tse phelang tse nang le carbon.Mosebetsi oa eona ke ho ntlafatsa monono oa mobu, ho fana ka phepo ea limela, le ho ntlafatsa boleng ba lijalo.E loketse manyolo a tlhaho a entsoeng ka moiteli oa liphoofolo le likhoho, masala a liphoofolo le limela le lihlahisoa tsa liphoofolo le limela, tse lomositsoeng le ho bola.

Moiteli oa likolobe o na le lintho tse phelang tse fokolang ho feta moiteli oa khomo 'me o bola kapele.Manyolo a na le naetrojene le phosphorus e ngata, 'me tekanyo ea tšebeliso ea limatlafatsi ea manyolo a likolobe ke 70%, e leng manyolo a bohlokoa haholo a tlhaho.

Litšupiso tsa Marang-rang li bontša hore moiteli o fapaneng oa liphoofolo o tlameha ho eketsoa ka litaba tse fapaneng tsa lisebelisoa tsa tokiso ea khabone ka lebaka la likhakanyo tsa bona tse fapaneng tsa khabone-nitrogen.Ka kakaretso, karolelano ea carbon-nitrogen bakeng sa ho belisoa e ka ba 25-35.Karolelano ea carbon ho nitrogen ea moiteli oa likolobe e ka ba 16-20.

Karolelano ea carbon-nitrogen ea moiteli oa liphoofolo tse ruuoang le likhoho tse tsoang libakeng tse fapaneng le lijo tse fapaneng le tsona li tla fapana.Hoa hlokahala ho lokisa karo-karolelano ea carbon-nitrogen ho etsa hore qubu e bole ho latela maemo a sebaka ka seng le karolelano ea 'nete ea carbon-nitrogen ea moiteli.

Mokhoa oa tlhahiso ea manyolo a manyolo a likolobe:

Ho belisoa→ho pshatla→ho hlohlelletsa le ho kopanya→granulation→ho omisa→ho pholisa→ho hloeka→ho paka le ho boloka thepa.

1. Ho bela

Ho belisoa ho lekaneng ke motheo oa tlhahiso ea manyolo a manyolo a boleng bo holimo.Mochini o fetolang qubu o hlokomela ho belisoa le ho etsa mosuela ka botlalo, 'me o khona ho lemoha ho fetoha ha qubu le ho belisoa, e leng ho ntlafatsang lebelo la ho belisoa ha aerobic.

2. Qhata

Sesila se sebelisoa haholo ts'ebetsong ea tlhahiso ea manyolo a tlhaho, 'me se na le phello e ntle ea ho sila lintho tse tala tse kang moiteli oa likhoho le seretse.

3. Hlohlelletsa

Ka mor'a hore lihlahisoa tse tala li pshatlehe, li kopantsoe le lisebelisoa tse ling tse thusang ka ho lekana ebe li kenngoa granulated.

4. Granulation

Mokhoa oa granulation ke karolo ea mantlha ea mohala oa tlhahiso ea manyolo.Granulator ea manyolo ea manyolo e fihlella granulation ea boleng bo holimo ka ho kopanya khafetsa, ho thulana, ho kenya, spheroidization, granulation le densification.

5. Ho omisa le ho pholisa

Se omisitsoeng sa drum se etsa hore thepa e kopane ka ho feletseng le moea o chesang le ho fokotsa mongobo oa likaroloana.

Ha e ntse e fokotsa mocheso oa li-pellets, moropa o pholileng o fokotsa metsi a li-pellets hape, 'me hoo e ka bang 3% ea metsi e ka ntšoa ka mokhoa oa ho pholisa.

6. Tlhahlobo

Ka mor'a ho pholile, li-powders tsohle le likaroloana tse sa tšoanelehang li ka hlahlojoa ka mochine oa sieving oa drum.

7. Sephutheloana

Ena ke ts'ebetso ea ho qetela ea tlhahiso.Mochini oa ho paka oa othomathike o ka itekang, oa tsamaisa le ho tiisa mokotla.

Kenyelletso ea lisebelisoa tsa mantlha tsa mochini oa tlhahiso ea manyolo a likolobe:

1. Thepa ea ho belisa: mochini o fetolang mofuta oa sejana, mochini o phetholang mofuta oa crawler, mochini o phetholang poleiti le mochini o lahlelang

2. Lisebelisoa tsa Crusher: semi-wet material crusher, vertical crusher

3. Lisebelisoa tsa motsoako: motsoako o otlolohileng, motsoako oa pan

4. Lisebelisoa tsa ho hlahloba: mochine oa ho hlahloba meropa

5. Sesebelisoa sa granulator: granulator ea leino le susumetsang, granulator ea disc, granulator ea extrusion, granulator ea moropa.

6. Lisebelisoa tsa ho omisa: Drum dryer

7. Thepa e pholileng: drum cooler

8. Lisebelisoa tse thusang: karohano e tiileng-metsi, phepelo ea bongata, mochini oa ho paka o itekanetseng, mochini o tsamaisang lebanta.

Haholo-holo ho tsoa ho lintlha tse latelang ho laola mokhoa oa ho belisa:

Mongobo

E le ho etsa bonnete ba tsoelo-pele e ntle ea manyolo ka nako ea ts'ebetso ea manyolo, palo ea metsi mothating oa pele oa manyolo a lokela ho bolokoa ho 50-60%.Kamora moo, mongobo o bolokoa ho 40% ho isa ho 50%.Ha e le hantle, ha ho marotholi a metsi a ka lutlang.Kamora ho belisoa, mongobo oa thepa e tala o lokela ho laoloa ka tlase ho 30%.Haeba mongobo o phahame, o lokela ho omisoa ka 80°C.

Taolo ea mocheso

Mocheso ke phello ea ts'ebetso ea likokoana-hloko.Stacking ke tsela e 'ngoe ea ho laola mocheso.Ka ho fetola stack, mocheso oa stack o ka laoloa ka katleho ho eketsa mouoane oa metsi le ho lumella moea o hloekileng hore o kene ka har'a stack.Ka ho phethola nako le nako, mocheso le mocheso o phahameng oa nako ea ho belisoa li ka laoloa ka katleho.

Karolelano ea carbon ho naetrojene

Khabone le naetrojene tse loketseng li ka khothaletsa ho belisoa ha manyolo ka boreleli.Likokoana-hloko li theha protoplasm ea likokoana-hloko ts'ebetsong ea ho belisoa.Bafuputsi ba khothaletsa moiteli o loketseng oa C/N oa 20-30%.

Karolelano ea khabone ho naetrojene ea manyolo a tlhaho e ka fetoloa ka ho eketsa lintho tse nang le khabone e phahameng kapa naetrojene e phahameng.Lisebelisoa tse ling tse kang joang, mofoka, makala a shoeleng le makhasi a ka sebelisoa e le li-additives tse phahameng tsa carbon.E ka khothaletsa kholo le ho ikatisa ha likokoana-hloko le ho potlakisa kholo ea manyolo ka litlama.

taolo ea pH

Boleng ba pH bo ama ts'ebetso eohle ea ho belisoa.Mokhahlelong oa pele oa manyolo, boleng ba pH bo tla ama tšebetso ea libaktheria.
