Taba ea Kopo ea Setsi sa Motlakase se Iketselitsoeng Setsing se Itseng sa Lipampiri se Fujian

Khamphani e itseng e nang le mekoloto e fokolang ea indasteri ea pampiri e Profinseng ea Fujian ke e 'ngoe ea likhoebo tse kholo ka ho fetisisa tsa tlhahiso ea pampiri profenseng eo hape ke khoebo ea bohlokoa ea provense e kopanyang ho etsa pampiri ka bongata le mocheso o kopaneng le phepelo ea motlakase. Kakaretso ea tekanyo ea kaho ea morero e kenyelletsa lihlopha tse 'nè tsa "630 t/h ea mocheso o phahameng le likhatello tse ngata tsa mafura tse potolohang metsi a phallang + 80 MW back-press steam turbines + 80 MW generators," ka boiler e le 'ngoe e sebetsang e le setsi sa polokelo. Morero o kengoa ts'ebetsong ka mekhahlelo e 'meli: mohato oa pele o na le lihlopha tse tharo tsa tlhophiso ea lisebelisoa tse boletsoeng ka holimo, ha karolo ea bobeli e eketsa sete e le' ngoe e eketsehileng.

Tlhahlobo ea boleng ba metsi e bapala karolo ea bohlokoa tlhahlobong ea boiler, kaha boleng ba metsi bo ama ts'ebetso ea boiler ka kotloloho. Boleng bo bobe ba metsi bo ka lebisa ho se sebetse hantle, ho senyeha ha lisebelisoa, le likotsi tse ka bang teng tsa polokeho bakeng sa basebetsi. Ts'ebetsong ea lisebelisoa tsa ho hlahloba boleng ba metsi a marang-rang ho fokotsa haholo kotsi ea liketsahalo tsa tšireletso tse amanang le boiler, ka hona ho netefatsa ts'ebetso e sireletsehileng le e tsitsitseng ea tsamaiso ea boiler.

pH ea boleng: pH ea metsi a boiler e hloka ho bolokoa sebakeng se itseng (ka tloaelo 9-11). Haeba e le tlase haholo (e nang le asiti), e tla senya likarolo tsa tšepe tsa boiler (tse kang liphaephe tsa tšepe le meropa ea mouoane). Haeba e phahame haholo (ka matla a alkaline), e ka 'na ea etsa hore filimi e sireletsang holim'a tšepe e theohe, e lebisang ho kutu ea alkaline. PH e nepahetseng e ka boela ea thibela phello e senyang ea carbon dioxide e sa lefelloeng metsing le ho fokotsa kotsi ea ho eketseha ha lipeipi.

Conductivity: Conductivity e bonahatsa kakaretso ea li-ion tse qhibilihisitsoeng metsing. Ha boleng bo phahame, ho na le litšila tse ngata (tse kang matsoai) metsing. Ts'ebetso e phahameng ka ho fetesisa e ka lebisa ho sekhahla sa boiler, ho potlakisa kutu, hape ho ka ama boleng ba mouoane (joalo ka ho jara letsoai), ho fokotsa ts'ebetso ea mocheso, esita le ho baka liketsahalo tsa polokeho joalo ka ho phatloha ha liphaephe.

Oksijene e qhibilihisitsoeng: Oksijene e qhibilihisitsoeng ka metsing ke sesosa se ka sehloohong sa ho bola ha oksijene ea litšepe tsa boiler, haholo-holo ho litsebi tsa moruo le marako a pholileng ka metsi. E ka lebisa ho pitting le ho fokotseha ha holim'a tšepe, 'me maemong a boima, lisebelisoa tsa ho lutla. Hoa hlokahala ho laola oksijene e qhibilihisitsoeng ka tekanyo e tlaase ka ho fetisisa (hangata ≤ 0.05 mg / L) ka phekolo ea deaeration (e kang thermal deaeration le chemical deaeration).

Silicate: Silicate e na le tšekamelo ea ho volatilize ka mouoane tlas'a mocheso o phahameng le khatello, ho kenya li-blades tsa turbine ho etsa silicate scale, e leng ho fokotsang katleho ea turbine esita le ho ama ts'ebetso ea eona e sireletsehileng. Ho lekola silicate ho ka laola litaba tsa silicate ka metsing a boiler, ho netefatsa boleng ba mouoane, le ho thibela ho phahama ha turbine.

Motso oa phosphate: Ho eketsa letsoai la phosphate (joaloka trisodium phosphate) metsing a belang ho ka sebetsana le li-ion tsa calcium le magnesium ho etsa precipitates e bonolo ea phosphate, ho thibela ho thehoa ha sekhahla se thata (ke hore, "phekolo ea thibelo ea phosphate scale"). Ho beha leihlo mokoloko oa motso oa phosphate ho etsa bonnete ba hore o lula sebakeng se lekaneng (ka tloaelo 5-15 mg/L). Maemo a phahameng ka ho fetesisa a ka etsa hore motso oa phosphate o jeoe ke mouoane, athe maemo a tlase haholo a tla hloleha ho thibela ka nepo sebopeho sa sekala.

Li-ion tsa sodium: Li-ion tsa sodium ke li-ion tse tloaelehileng tse arohaneng le letsoai metsing, 'me litaba tsa tsona li ka bonahatsa ka mokhoa o sa tobang tekanyo ea khatello ea metsi a boiler le boemo ba letsoai le tsamaisoang ke mouoane. Haeba motsoako oa sodium ion o phahame haholo, o bontša hore metsi a boiler a tsitsitse ka botebo, a atisang ho baka sekhahla le ho senya; li-ion tse feteletseng tsa sodium ka mouoane li tla boela li lebise ho bokella letsoai ka har'a turbine ea mouoane, e amang ts'ebetso ea lisebelisoa.
