Lub tshuab zeb thee yog ib feem tseem ceeb ntawm lub tshuab pulverizing thiab yog ib qho khoom siv hluav taws xob tseem ceeb hauv lub chaw tsim hluav taws xob. Nws txoj haujlwm tseem ceeb yog rhuav thiab sib tsoo thee ua cov thee pulverized los muab cov khoom siv boiler, nws qhov kev teeb tsa yuav cuam tshuam ncaj qha rau kev nyab xeeb thiab kev lag luam ntawm lub tshuab. Vim tias qhov kev hloov pauv ntawm cov tshuab zeb thee sib txawv rau ntau hom thee sib txawv heev, ua ke nrog qhov xwm txheej tiag tiag ntawm kev faib cov khoom thee tsis sib xws hauv Suav teb, qhov zoo ntawm cov khoom thee yuav cuam tshuam ncaj qha rau kev lag luam ntawm lub tshuab pulverizing. Yog li, yuav tsum xaiv cov khoom siv sib tsoo thee li cas?Cov Tshuab HCMUa ib lub chaw tsim khoom siv zeb thee, yuav qhia txog lub hauv paus ntawm kev xaiv zeb thee. Muaj ntau hom zeb thee, raws li qhov ceev ntawm qhov sib tsoo ua haujlwm ntawm cov khoom siv zeb thee, pawg xaiv khoom siv zeb thee tuaj yeem muab faib ua peb hom, uas yog: zeb thee ceev qis, zeb thee ceev nruab nrab thiab zeb thee ceev siab. Cov hauv qab no yuav qhia txog kev xaiv ntawm peb lub tshuab sib tsoo thee no.
Kev xaiv cov khoom siv zeb thee 1: zeb thee ceev qis
Tus sawv cev ntawm lub tshuab zeb thee qeeb qeeb yog lub tshuab zeb pob. Lub hauv paus ntsiab lus ua haujlwm yog: lub cev muaj zog siab los ntawm lub gearbox los tsav lub phaj puag ncig hnyav no, lub pob hlau hauv lub tshuab yooj yim tig mus rau qee qhov siab thiab tom qab ntawd poob, los ntawm kev cuam tshuam ntawm lub pob hlau rau ntawm cov thee thiab ntawm lub pob hlau, ntawm lub pob hlau thiab lub phaj tiv thaiv, cov thee raug sib tsoo. Cov thee uas tsis tsim nyog dhau lawm raug cais thaum nws ntws los ntawm lub tshuab sib cais hmoov ntxhib ntawm tom qab ntawm lub tshuab zeb pob, thiab tom qab ntawd xa mus rau lub phaj puag ncig los ntawm lub raj hmoov rov qab los rau kev sib tsoo dua. Ntxiv nrog rau kev thauj cov hmoov thee, cua kub kuj ua lub luag haujlwm ntawm kev ziab thee. Yog li ntawd, cua kub kuj hu ua desiccant hauv lub kaw lus hmoov. Cov khoom muaj cov yam ntxwv ntawm lub sijhawm ua haujlwm ntev, yooj yim txij nkawm, cov zis ruaj khov thiab zoo, muaj peev xwm khaws cia ntau, teb sai, yooj yim ua haujlwm, qhov sib piv ntawm huab cua thiab thee qis, txuag cov tshuab thee seem, ntau yam kev sib tsoo thee thiab lwm yam. Nws feem ntau yog siv rau cov thee tawv thiab nruab nrab-hardness, tshwj xeeb tshaj yog rau cov thee uas muaj cov ntsiab lus volatile siab thiab cov khoom siv abrasive muaj zog. Txawm li cas los xij, lub tshuab zeb pob qeeb qeeb no loj heev, siv hlau ntau, siv ntau thaj av, thiab muaj kev nqis peev thaum pib siab. Yog li lub tshuab zeb pob no tsim nyog rau kev ua haujlwm puv ntoob.
Cov khoom siv zeb thee hom 2:lub tshuab zeb thee ceev nruab nrab
Lub tshuab zeb thee ceev nruab nrab kuj hu ua lub tshuab zeb thee ntsug, uas yog tus yam ntxwv los ntawm cov khoom sib tsoo uas muaj ob pawg ntawm kev txav mus los ntawm lub cev sib tsoo. Cov thee raug nias thiab sib tsoo ntawm qhov chaw ntawm ob lub cev sib tsoo thiab raug tsoo. Tib lub sijhawm, cua kub los ntawm lub tshuab zeb ua rau cov thee qhuav thiab xa cov thee pulverized mus rau lub separator ntawm sab saud ntawm thaj chaw zeb. Tom qab sib cais, cov thee pulverized ntawm qee qhov loj me me raug coj tawm ntawm lub tshuab zeb nrog cov cua ntws, thiab cov thee pulverized coarse raug xa rov qab mus rau thaj chaw sib tsoo rau kev sib tsoo dua. Lub tshuab zeb thee ceev nruab nrab muaj qhov zoo ntawm cov khoom siv compact, qhov chaw me me, kev siv hluav taws xob txuag (kwv yees li 50% ~ 75% ntawm lub tshuab zeb pob), suab nrov qis, lub teeb thiab kev tswj hwm kev ua haujlwm rhiab heev. Tab sis nws tsis haum rau kev sib tsoo thee nyuaj dua.
Kev xaiv cov khoom siv zeb thee 3: zeb thee ceev ceev
Qhov ceev ntawm lub tshuab zeb thee ceev yog 500 ~ 1500 r / min, uas feem ntau yog tsim los ntawm lub rotor ceev thiab lub plhaub sib tsoo. Kev sib tsoo kiv cua thiab kev sib tsoo rauj thiab lwm yam. Hauv lub tshuab zeb, cov thee raug tsoo los ntawm kev sib tsoo ntawm qhov cuam tshuam ceev thiab lub plhaub sib tsoo thiab kev sib tsoo ntawm cov thee. Hom tshuab zeb thee thiab cov tshuab sib cais thee no tsim ib qho tag nrho, cov qauv yooj yim, me me, kev nqis peev thawj zaug yog qis, tshwj xeeb tshaj yog tsim rau kev sib tsoo cov lignite uas muaj dej noo ntau thiab cov ntsiab lus volatile siab, yooj yim rau kev sib tsoo cov thee bituminous. Txawm li cas los xij, vim tias lub phaj cuam tshuam raug eroded ncaj qha thiab hnav los ntawm cov cua ntws, nws lub neej kev pabcuam feem ntau tsuas yog li 1000h thaum sib tsoo lignite, hloov pauv ntau zaus, thiab cov dej hauv av yuav tsum tsis txhob siab dhau, uas feem ntau yog siv rau cov boilers ncaj qha hauv cov chaw tsim hluav taws xob, thiab yuav tsum tsis txhob siv rau cov chaw ua haujlwm txhaj tshuaj rauv taws.
Peb hom khoom siv sib tsoo thee saum toj no muaj qhov zoo thiab qhov tsis zoo, thaum xaiv cov khoom siv sib tsoo thee, nws yog qhov tsim nyog los xav txog kev xaiv tag nrho ntawm lub tshuab pulverizing. Lub tshuab hmoov tuaj yeem muab faib ua ob pawg: hom tshuab ncaj qha thiab hom cia nruab nrab (hu ua hom cia). Hauv lub tshuab pulverization ncaj qha, thee raug zom ua cov thee pulverized los ntawm lub zeb zeb thee thiab tom qab ntawd tshuab ncaj qha rau hauv lub cub tawg rau kev hlawv. Hauv lub tshuab pulverization cia, cov thee pulverized raug khaws cia ua ntej hauv lub thoob khib nyiab pulverized, thiab tom qab ntawd raws li qhov xav tau ntawm lub boiler load, cov thee pulverized raug xa los ntawm lub thoob khib nyiab pulverized mus rau lub cub tawg rau kev hlawv los ntawm lub pulverizer. Cov tshuab pulverizing sib txawv kuj tsim nyog rau ntau hom thee thiab cov khoom siv sib tsoo thee xaiv. Raws li lub tshuab pulverization, peb tau sau cov hauv paus hauv qab no rau kev xaiv lub zeb zeb thee:
(1) Lub tshuab zeb hlau pob zeb hauv nruab nrab lub thoob khib nyiab hom cua sov hmoov system: tuaj yeem siv rau anthracite (Vsr <9%) thiab hnav hauv qhov muaj zog saum cov thee.
(2) Lub tshuab xa hmoov av nruab nrab rau pob zeb: feem ntau yog siv rau cov thee uas muaj zog hnav thiab nruab nrab volatile (Var-19% ~ 27%) bituminous thee.
(3) Ob chav-hauv ob chav-tawm steel pob zeb ncaj qha tshuab tshuab 22-241: rau nruab nrab-siab volatile (Vs.7-27% ~ 40%) bituminous thee.
(4) Lub tshuab cua tshuab ncaj qha rau lub tshuab cua nruab nrab: tsim nyog rau kev sib tsoo cov thee bituminous nrog cov ntsiab lus volatile siab (Vanr-27% ~ 40%), cov dej noo siab (sab nraud dej noo Mp≤15%) thiab hnav muaj zog, nrog rau cov thee cuav poob qis dua qhov muaj zog, kev ua haujlwm ntawm cov thee combustion yog flammable, thiab cov thee pulverized fineness ua tau raws li qhov yuav tsum tau ua ntawm lub tshuab zeb thee.
(5) Lub tshuab cua tshuab ncaj qha los ntawm lub kiv cua: tsim nyog rau kev yaig lignite Ke≤3.5 thiab 50 MW thiab qis dua bituminous thee chav boiler
Thaum xaiv cov khoom siv thee zeb, nws yuav tsum tau txiav txim siab raws li cov yam ntxwv ntawm kev sib xyaw, kev hnav thiab kev tawg ntawm thee, cov yam ntxwv ntawm kev sib xyaw ntawm thee zeb thiab cov kev xav tau ntawm kev sib xyaw ua ke ntawm cov thee zoo, ua ke nrog cov qauv cub tawg thiab cov qauv hlawv ntawm lub boiler, thiab xav txog kev nqis peev, kev saib xyuas thiab kev ua haujlwm ntawm lub zog fais fab thiab cov khoom siv txhawb nqa, kev muab cov khoom seem, qhov chaw ntawm thee thiab cov khib nyiab hauv thee thiab lwm yam. Txhawm rau kom ua tiav qhov sib phim tsim nyog ntawm lub kaw lus pulverizing, cov khoom siv combustion thiab lub cub tawg boiler, kom ntseeg tau tias muaj kev nyab xeeb thiab kev lag luam ntawm lub tshuab.
