Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev lag luam qhov cub?
Industrial tunnel furnace yog ib qho kev lag luam qhov cub dav siv hauv kev lag luam xws li kev ua hlau, iav tsim, thiab ceramic sintering. Kev ua haujlwm raug yog tus yuam sij rau kev ua haujlwm ib txwm muaj ntawm cov khoom siv hluav taws xob, ua kom cov khoom tsim tau zoo thiab kev nyab xeeb. Cov hauv qab no yuav muab cov ncauj lus qhia ntxaws ntxaws rau cov ntsiab lus ntawm kev ua haujlwm ntawm cov qhov cub hluav taws xob.
1, Lub tshuab ua haujlwm hauv pem hauv ntej
Tig lub kiv cua: Muaj qhov cub rauv taws yuav tsum muaj cua tshuab ntau kom ntseeg tau tias qhov kub thiab txias ruaj khov hauv qhov cub. Ua ntej ua haujlwm ntawm lub qhov cub, tus neeg teb xov tooj yuav tsum xyuas kom meej tias cov kiv cua thiab qhov cua tshuab ua haujlwm zoo.
Kev tswj qhov kub thiab txias: Raws li cov txheej txheem tsim khoom, qhov kub ntawm cov khoom siv hluav taws xob yuav tsum tau tswj kom raug. Ua ntej ua haujlwm rau lub cub tawg, nws yog ib qho tsim nyog yuav tsum ntsuas thiab kho qhov ntsuas kub kom ntseeg tau tias qhov kub thiab txias hauv qhov cub.
Tshawb xyuas cov khoom siv roj: Cov khoom siv hluav taws xob feem ntau siv cov thee, nkev, roj, thiab lwm yam ua roj. Ua ntej ua haujlwm ntawm lub qhov cub, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj roj txaus thiab tshuaj xyuas cov roj kom zoo thiab kev nyab xeeb.
2, Ignition thiab preheating
Ntxuav lub cub tawg: Ua ntej ignition, nws yog ib qho tsim nyog yuav tsum tau ntxuav lub cub tawg kom tshem tawm cov roj seem, tshauv, thiab lwm yam impurities, kom tsis txhob muaj kev cuam tshuam rau qhov hluav taws kub thiab qhov chaw ntawm lub cub tawg.
Kev ua haujlwm ignition: Ua ntej ignition, nws yog ib qho tsim nyog yuav tsum xyuas kom meej tias cov khoom siv hluav taws xob tau npaj kom txaus, xws li lub igniter, spark, thiab lwm yam. Thaum igniting, nws yuav tsum tau ua raws li cov txheej txheem ignition ntawm lub qhov cub thiab maj mam ignite cov roj. Tom qab ignition, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas qhov xwm txheej ntawm cov nplaim taws kom ntseeg tau tias muaj kev sib tsoo.
Preheating lag luam: Tom qab ignition, maj mam ua haujlwm preheating yuav tsum tau. Raws li cov txheej txheem tsim khoom, lub sijhawm preheating thiab kub yuav tsum tau txiav txim siab ua ntej thaum preheating. Maj mam nce qhov kub ntawm lub cub tawg kom ntseeg tau tias txhua qhov chaw ntawm lub qhov cub hluav taws xob muaj cua sov zoo sib xws, kom tsis txhob muaj kev puas tsuaj los ntawm thermal stress.
Kev tswj qhov system: Cov kev tswj hwm ntawm lub qhov cub hluav taws xob feem ntau suav nrog kev tswj kub, tswj siab, thiab lwm yam. Kev tswj qhov kub thiab txias yog ib qho tseem ceeb tswj tsis tau rau lub qhov cub, feem ntau yog siv cov khoom siv xws li thermocouples lossis infrared ntsuas kub los saib xyuas qhov kub hauv chav cua sov, thiab tswj qhov kub thiab txias los ntawm kev tswj cov cua sov ntawm cov cua sov. Kev tswj lub siab yog qhov tseem ceeb ntawm kev sib txuas kom ntseeg tau tias muaj kev sib xyaw ua ke thiab tiv thaiv kev tawg hauv lub combustion chamber. Nws yog ib qho tsim nyog yuav tsum tswj kom muaj lub siab tsim nyog los ntawm kev tswj cov khoom siv roj, cov pa oxygen, thiab cov tshuab emission.
Emission system: Lub emission system ntawm industrial tunnel furnaces yog lub luag hauj lwm rau kev kho thiab tshem tawm cov pa khib nyiab generated los ntawm combustion. Kev kho cov roj khib nyiab suav nrog cov txheej txheem xws li tshem tawm plua plav, desulfurization, thiab denitrification kom ntseeg tau tias cov pa hluav taws xob ua tau raws li cov qauv ib puag ncig. Kev kho cov pa roj feem ntau suav nrog cov khoom siv xws li cov khoom siv plua plav, ntauwd absorbers, thiab cov khoom siv ammonia desulfurization. Cov plua plav collectors feem ntau yog siv los tshem tawm cov pa luam yeeb thiab cov khoom, ntauwd absorbers yog siv rau desulfurization, thiab cov khoom siv ammonia desulfurization siv cov dej ammonia los ua rau SO2 hauv cov pa roj los tsim ammonium sulfate rau desulfurization.
