Mokhoa oa ho ntlafatsa katleho ea tlhahiso indastering ea ho etsa pampiri ka polyacrylamide

Polyacrylamideke tlatsetso e sebelisoang haholo indastering ea pampiri. Polyacrylamide (PAM), joalo ka polymer e qhibilihang ka metsing, e na le flocculation e ntle haholo, e teteaneng, e qhalakantsoeng le lintho tse ling. E tla sebelisoa lits'ebetsong tse fapaneng tse fapaneng tse nang le mesebetsi e fapaneng. Indastering ea ho etsa pampiri, PAM e bapala karolo ea bohlokoahali. E tlisitse melemo e meholo ea moruo indastering ea ho etsa pampiri ka ho ntlafatsa thepa ea makhasi le ho eketsa ts'ebetso ea mochini oa pampiri. Sehlooho sena se tla tšohla ka ho qaqileng tšebeliso ea polyacrylamide tlhahiso ea pampiri le phello ea eona ho ntlafatsa katleho ea tlhahiso.

Lintho tsa motheo le mesebetsi ea polyacrylamide

Polyacrylamide ke polymer e phahameng ea molek'hule e ka aroloa ka mefuta ea nonionic, anionic, cationic le amphoteric ho latela thepa ea eona ea tefiso. Ha PAM e qhibiliha ka metsing, 'me sebopeho sa eona sa molek'hule se selelele se e nolofalletsa ho ba le mesebetsi e babatsehang e kang flocculation, thickening, thuso ea ho boloka, le thuso ea ho hloekisa. Indastering ea pampiri, polyacrylamide e sebelisoa haholo maemong a latelang:

1. Thuso ea ho boloka:

Limolek'hule tsa PAM li na le sebopeho se selelele sa ketane 'me li ka khabisoa holim'a likhoele le li-filler ho etsa marokho. Ka hona ho ntlafatsa sekhahla sa ho boloka li-filler le likhoele ho webosaete ea pampiri. Fokotsa tahlehelo ea fiber metsing a masoeu le ho fokotsa tahlehelo ea thepa e tala. Ka ho eketsa sekhahla sa ho boloka li-fillers le likhoele, thepa ea 'mele ea pampiri joalo ka boreleli, khatiso le matla li ka ntlafatsoa.

2. Thuso ea sefe:

Ntlafatsa ts'ebetso ea ho tlosa metsi a makhasi, potlakisa ts'ebetso ea ho hloekisa metsi le ho fokotsa tšebeliso ea matla.

3. Flocculant:

Ho potlakisa ho felloa ke metsi 'meleng: PAM e khona ho thellisa likhoele tse nyane, li-filler le lintho tse ling tse emisitsoeng ka har'a makhasi ho etsa lihlopha tse kholo tsa likaroloana, ho potlakisa ho rarolloa ha likhoerekhoere le ho felloa ke metsi, le ho fokotsa litšenyehelo tsa kalafo ea seretse.

Ntlafatsa boleng ba metsi: PAM e ka khona ho tlosa lintho tse tiileng tse emisitsoeng le lintho tse phelang metsing a litšila, ho fokotsa BOD le COD metsing a litšila, ho ntlafatsa boleng ba metsi le ho fokotsa tšilafalo ea tikoloho.

4. Ea qhalaneng:

Thibela fiber agglomeration: PAM e ka thibela ka katleho ho kopanya fiber ka har'a makhasi, ea ntlafatsa ho tšoana ha makhasi, le ho ntlafatsa boleng ba pampiri.

Tšebeliso ea polyacrylamide ho theknoloji ea ho etsa pampiri

1. Mokhahlelo oa ho lokisetsa makhasi

Nakong ea ts'ebetso ea ho lokisa makhasi, likhoele tse ntle le li-filler li lahleheloa habonolo ke metsi a litšila, tse bakang litšila le tšilafalo ea tikoloho. Ho sebelisa cationic Polyacrylamide e le thuso ea ho boloka ho ka tšoara le ho lokisa likhoele tse nyane le li-filler ka har'a makhasi ka tefiso ea neutralization le borokho. Sena ha se fokotse feela tahlehelo ea likhoele, empa hape se fokotsa ho jara kalafo ea likhoerekhoere.

2. Mochine oa pampiri oa ho qetela oa tsamaiso ea metsi

Mochine oa ho qetela oa mochini oa pampiri, ho felloa ke metsi ka potlako ke senotlolo sa ho ntlafatsa katleho ea tlhahiso. Anionic kapa nonionic polyacrylamide ka sebelisoa e le filtara thuso ho etsa hore ho be bonolo hore metsi ho baleha ho tswa ho faeba netweke sebopeho ka ho ntlafatsa flocculation pakeng tsa likhoele. Ts'ebetso ena e khutsufatsa haholo nako ea ho felloa ke metsi 'meleng ha e ntse e fokotsa tšebeliso ea matla nakong ea ho omisa.

3. Sethala sa ho etsa pampiri

E le dispersant, polyacrylamide ka ka katleho thibela faeba flocculation le ho ntlafatsa ho tšoana le bokaholimo boreleli ba pampiri. Ka ho khetha ka hloko boima ba limolek'hule le tefiso ea tefiso ea PAM, thepa ea 'mele ea pampiri e phethiloeng, joalo ka matla a thata le matla a tabohang, le eona e ka ntlafatsoa. Ho feta moo, polyacrylamide e ka boela ea ntlafatsa phello ea ho roala ha pampiri e koahetsoeng le ho etsa hore mosebetsi oa khatiso oa pampiri o be betere.

Melemo ea mantlha ea polyacrylamide ho ntlafatsa katleho ea tlhahiso

1. Fokotsa tahlehelo ea thepa e tala

Tšebeliso ea lithuso tsa ho boloka e ntlafatsa haholo sekhahla sa ho boloka likhoele tse ntle le li-filler ho pulp, e fokotsa tšebeliso ea thepa e tala, 'me e boloka ka kotloloho litšenyehelo tsa tlhahiso.

2. Potlakisa ts'ebetso ea dehydration

Kenyelletso ea li-filter aids e etsa hore mokhoa oa ho ntša metsi o atlehe haholoanyane, ka hona o eketsa lebelo la mochini oa pampiri le ho khutsufatsa potoloho ea tlhahiso. Sena ha se eke feela matla a tlhahiso a ikemetseng, empa hape se fokotsa tšebeliso ea matla.

3. Fokotsa khatello ea metsi a litšila

Ka ho ntlafatsa phello flocculation, Polyacrylamide ka ka katleho fokotsa diteng tsa solids emisitswe ka metsi a litšila, ho fokotsa loading ea likhoerekhoere thepa kalafo ho tloha mohloling le ho fokotsa ditjeo tshireletso tikoloho ya likhoebo.

4. Ntlafatsa boleng ba pampiri

Ts'ebeliso ea li-dispersants e etsa hore kabo ea fiber ea pampiri e ts'oane haholoanyane, e ntlafatsa haholo thepa ea 'mele le pono ea pampiri,' me e ntlafatsa tlholisano ea 'maraka ea sehlahisoa.

Lintlha tse amang phello ea tšebeliso ea polyacrylamide

Bakeng sa ho fana ka papali e felletseng ts'ebetsong ea polyacrylamide, lintlha tse latelang li hloka ho tsepamisa maikutlo ho:

1. Khetho ea mohlala oa PAM

Mekhoa e fapaneng ea ho etsa pampiri le mefuta ea pampiri e na le litlhoko tse fapaneng bakeng sa boima ba molek'hule le tefiso ea tefiso ea PAM. Boima bo phahameng ba molek'hule PAM e loketse ho phalla le ho thusa ho hloekisa, ha boima bo tlaase ba molek'hule PAM bo loketse ho qhalakanngoa.

2. Ho eketsa chelete le mokhoa oa ho eketsa

Palo ea PAM e kenyellelitsoeng e tlameha ho laoloa ka nepo. Chelete e feteletseng e ka baka litlamorao tse mpe, joalo ka ho ama ts'ebetso ea ho felloa ke metsi 'meleng kapa ho eketsa litšenyehelo tsa tlhahiso. Ka nako e ts'oanang, mokhoa oa ho kenyelletsa o qhalakantsoeng ka mokhoa o ts'oanang o lokela ho sebelisoa ho qoba ho bokellana ha libaka tse amang phello.

3. Maemo a tshebetso

Mocheso, pH le maemo a metsi kaofela li ama ts'ebetso ea PAM. Ka mohlala, PAM ea cationic e sebetsa hantle ka ho se nke lehlakore ho isa maemong a acidic hanyenyane, ha anionic PAM e loketse libaka tsa alkaline.

E le tlatsetso e nang le mesebetsi e mengata indastering ea ho etsa pampiri, polyacrylamide e phetha karolo ea bohlokoa ho ntlafatsa katleho ea tlhahiso, ho fokotsa litšenyehelo tsa tlhahiso le ho ntlafatsa boleng ba sehlahisoa ka thepa ea eona e babatsehang ea ho phalla, ho boloka, ho sefa le ho hasana. Likopong tse sebetsang, lik'hamphani li hloka ho khetha le ho ntlafatsa maemo a ts'ebeliso ea PAM ho latela litšoaneleho tsa bona tsa ts'ebetso le litlhoko tsa ho fihlela melemo e metle ea moruo le tikoloho.
