Technical field:
Cov khoom no muaj feem xyuam rau lub teb kiln roj combustion system siv nyob rau hauv metallurgical kev lag luam, tshwj xeeb tshaj yog rau ib tug low-pressure rotary kiln roj combustion ntaus ntawv.
Cov cuab yeej technology:
Tam sim no, cov pa roj combustion system ntawm teb kilns nyob rau hauv metallurgical kev lag luam nyob rau hauv Tuam Tshoj yog tsim ib tug gas pressurization chaw nres tsheb nyob ib ncig ntawm lub rotary kilns, nruab nrog ob peb lub zog loj hauv paus tshuab blowers los hloov cov roj uas tsis tshua muaj siab mus rau hauv high-pressure gas kom tau raws li qhov xav tau ntawm cov roj combustion system. ntau lawm xav tau.Qhov no high-pressure gas combustion system muaj qhov tsis zoo hauv qab no: 1. Txhua qhov pib thiab kaw ntawm qhov chaw nres tsheb roj yog qhov nyuaj, siv zog ua haujlwm, thiab yuav tsum tau saib xyuas tshwj xeeb; 2.2. Cov nplaim hluav taws kub hnyiab ntawm cov txheej txheem combustion yog concentrated, combustion txhaj ceev ceev, cov nplaim hluav taws kub hnyiab tau ntev, thaum lub qhov cub tawg mus txog 1250 degrees, qhov kub ntawm qhov kub ntawm qhov kawg ntawm lub kiln. preheating seem ntawm lub cub tawg tuaj yeem ncav cuag 1150 ~ 1200 degree thaum qhov kub thiab txias yog 1300 degree, thiab qhov kub ntawm lub grate yuav tsum tsis txhob siab tshaj 1100 degree rau lub sij hawm ntev. cov khoom siv. Cov grate tuav feem ntau raug kaw rau kev saib xyuas vim yog combustion.3. Kev ntsuas kub qeeb qeeb ntawm kev sib xyaw ua ke.Yuav kom ncav cuag qhov kub kub li qub tom qab qhov hluav taws kub, cov cua kub ntau yuav tsum tau muab los ntawm cov cua kub ntawm cov cua txias, uas yuav siv sij hawm ntau tshaj 24 teev, nkim roj ntau, thiab txawm cuam tshuam ntau lawm.4. Lub chaw nres tsheb siab muaj ntau qhov tsis raug, uas muaj kev cuam tshuam zoo rau kev tsim khoom, lub sijhawm tu ncua ntev, tus nqi siab thiab kev siv hluav taws xob loj.
Lub tshuab hluav taws xob tsis tshua muaj hluav taws xob hluav taws xob ntawm cov hluav taws xob hluav taws xob tuaj yeem tshem tawm qhov chaw nres tsheb siab, xyuas kom cov nplaim hluav taws kub thiab qhov ntev ruaj khov ntawm cov roj burner nyob rau hauv cov pa roj tsawg, thiab qhov kub thiab txias tuaj yeem ua tau raws li qhov xav tau ntau lawm.
Kev daws teeb meem: suav nrog lub tshuab hluav taws xob hauv nruab nrab, cov roj nozzle vortex hniav thiab cov cua nozzle vortex hniav, cov roj nozzle vortex hniav thiab cov cua nozzle vortex hniav Lub kaum sab xis ntawm 15-30 degrees.
Nyob rau hauv cov tswv yim saum toj no, txoj kab uas hla ntawm lub hauv paus burner yuav ua tau ntau tshaj 600 hli, uas ua rau qhov kub thiab txias ntawm kiln tail thiab lub cub tawg lub taub hau yooj yim los tswj hauv qab no 1050 degree, thiab cov nplaim taws siv lub vojvoog yuav txo tau kom tshem tawm lub zos overburning ntawm lub qhov cub hauv ob sab phlu. .Nws tseem tuaj yeem tshem tawm lub nplhaib tsim ntawm lub hauv ob sab phlu.
Cov khoom zoo: 1. Ncua tseg qhov chaw nres tsheb cua siab, txo cov kev siv zog ntawm cov neeg ua haujlwm, txo cov khoom tsis zoo hauv kev tsim khoom, kom cov khoom tsis cuam tshuam los ntawm kev ua tsis zoo ntawm cov cua siab; 2.2. Ua kom lub cheeb ntawm lub hauv paus burner los ntawm kev hloov lub kaum sab xis ntawm lub rotating hniav ntawm cov roj nozzle thiab rotating hniav ntawm cov cua nozzle.Qhov kub sib txawv ntawm kiln kawg thiab kiln kawg yog feem ntau txog 250 degree nyob rau hauv cov txheej txheem ua hauj lwm.Thaum lub kiln. ncav cuag 1300 degree, qhov kub ntawm qhov cub thiab grate tuaj yeem tswj tau yooj yim hauv qab 1050 degree, uas txhim kho lub neej kev pab cuam ntawm kiln tail thiab grate, thiab tshem tawm ib feem ntau dhau ntawm qhov cub hauv ob sab phlu tshwm sim los ntawm kev txo cov nplaim taws siv hluav taws xob.3. Lub tshuab combustion tuaj yeem ua tau raws li cov txheej txheem yuav tsum tau ua hauv ob peb teev, thiab qhov kub thiab txias tuaj yeem ua tau raws li qhov xav tau ntau lawm hauv lub sijhawm luv.4. Txo kev nqis peev thiab downtime, txuag lub zog thiab txhim kho kev lag luam.
Cov khoom no suav nrog cov kav dej nkag, qhov chaw taws teeb, roj nozzle swirl vane thiab cua nozzle swirl vane
Nyob rau hauv cov txheej txheem ntau lawm, cov roj siab system raug tshem tawm tag nrho, txoj kab uas hla ntawm lub hauv paus burner yog nce mus rau ntau tshaj 600 mm, thiab cov roj cyclones yog nce.Lub kaum sab xis ntawm cov pa roj thiab cua cyclones txawv ntawm 15 mus rau 30 degrees nyob ntawm seb. ntawm qhov ntev, siv, thiab dav ntawm cov nplaim taws.Siv cov thawj pipeline gas direct combustion burner tsis tau tsuas yog ua tau raws li tus txheej txheem kub yuav tsum, tab sis kuj xyuas kom tsawg noj thiab high efficiency ntawm ntau lawm.The gas pressurization system tau raug tshem tawm tag. roj tuaj yeem hlawv ntawm qhov kub siab hauv qab no (2 kPa) kom ncav cuag qhov xav tau kub.
Tso tseg qhov chaw nres tsheb roj siab, txo kev nqis peev.
