Yuav Ua Li Cas Coal Chemical Thermocouples Txhim Kho Kev Nyab Xeeb hauv Gasification?

Thermocouples yog qhov tseem ceeb heev hauv kev txhim kho kev nyab xeeb hauv cov txheej txheem nyuaj thiab pheej hmoo siab thee gasification siv nyob rau hauv cov thee chemical sector. Cov cuab yeej ntsuas kub zoo tshaj plaws no yog cov neeg tsis paub zoo ua kom tag nrho cov txheej txheem tsis pub muaj kev kub ntxhov.
Coal gasification yog cov txheej txheem ntawm kev xa cov thee rau hauv cov pa roj carbon monoxide thiab hydrogen ua ke. Cov txheej txheem no tshwm sim nyob rau hauv lub xub ntiag ntawm sib txawv reactive compounds nyob rau hauv heev kub thiab pressures. Ntawm no, lub hauv paus rau thermocouples ua hauj lwm yog qhov zoo-paub Seebeck nyhuv. Ib qho hluav taws xob yog tsim thaum ob qho tib si hlau sib txuas ntawm qhov sib txuas thiab qhov kub sib txawv thoob plaws nws qhov tshwm sim. Qhov hluav taws xob no muaj cov txheej txheem ntawm kev ntsuas qhov ntsuas kub hauv qhov system gasification.
Ib txoj hauv kev tseem ceeb no cov thermocouples nce kev nyab xeeb yog los ntawm kev tswj qhov kub thiab txias. Kev tswj qhov kub kom zoo yog qhov tseem ceeb heev hauv lub tshuab hluav taws xob gasification. Qhov kub thiab txias heev tuaj yeem muaj ntau yam teeb meem. Piv txwv li, tej zaum nws yuav ua rau cov thee ua rau mob hnyav heev, ua rau carbon monoxide ntau dhau. Cov pa phem heev, cov pa roj carbon monoxide tuaj yeem ua rau muaj kev phom sij loj rau kev noj qab haus huv ntawm cov neeg ua haujlwm nyob ze los ntawm qhov siab dhau lawm. Tsis tas li ntawd, yog tias cov phab ntsa reactor lossis lwm yam khoom siv tsis tau tsim los tiv thaiv cov cua sov zoo li no, qhov kub thiab txias yuav ua rau lawv yaj. High precision thermocouples yuav ceev nrooj txheeb xyuas qhov kub tsis txawv txav. Kev saib xyuas qhov kub thiab txias tsis tu ncua thiab ceeb toom rau kev tswj hwm thaum muaj dab tsi mus tsis ncaj ncees lawm, lawv zoo li lub qhov muag saib xyuas ntawm cov txheej txheem gasification.
Hloov pauv, qhov kub qis dhau ntawm cov txheej txheem gasification tuaj yeem ua rau cov thee tsis ua kom tag nrho. Reactive thee tuaj yeem khaws cia hauv lub reactor uas tsis tau ua tiav. Qhov no tuaj yeem txhim kho lub kaw lus kaw nyob rau lub sijhawm, yog li ua rau cov roj ntws tsis zoo thiab qee zaum ua rau muaj kev kub ntxhov. Nyob rau hauv qhov xwm txheej phem tshaj plaws, qhov kev tsim ntawm lub siab tuaj yeem ua rau tawg. Cov thermocouples lav tias qhov kub nyob hauv qhov zoo tshaj plaws rau kev ua kom zoo gasification, yog li zam kom tsis txhob muaj kev phom sij. Nws zoo li muaj tus neeg tsav nkoj uas muaj peev xwm ntawm lub nkoj kom ntseeg tau tias lub nkoj tseem nyob ntawm txoj hauv kev thiab zam cov pob zeb uas tsis muaj qhov kub thiab txias - ua rau muaj teeb meem.
Tsis tas li ntawd, ua rau muaj kev nyab xeeb zoo heev yog lub neej ntev ntawm cov thee tshuaj thermocouples. Qhov kub thiab txias, corrosive gases, thiab feem ntau muaj kev kub ntxhov siab txhais tau hais tias qhov kev tawm tsam gasification. Cov thermocouples no yog tsim los ntawm cov khoom siv uas tuaj yeem muaj sia nyob raws li qhov xav tau ib puag ncig. Feem ntau yog tsim los ntawm cov khoom siv tshwj xeeb lossis cov khoom siv ceramic tiv taus corrosion thiab muaj peev xwm tiv taus cua sov, cov txheej txheem sab nrauv yuav tsum yog cov thermocouple tawg los ntawm corrosion los yog ib puag ncig degradation, nws yuav muab kev nyeem ntawv tsis zoo. Cov ntaub ntawv tsis raug no tuaj yeem cuam tshuam rau kev tswj hwm, yog li ua rau cov txheej txheem txaus ntshai. Piv txwv li, lub kaw lus tswj yuav txhawb nqa cov cua sov yog tias lub thermocouple corroded qhia qhov kub qis dua li qhov tiag, yog li skyrocketing qhov kub thiab ua rau tag nrho cov kev ua haujlwm.
Lub sij hawm tawm tsam sai ntawm cov thermocouples no kuj tseem ceeb heev. Kev hloov pauv kub hauv cov txheej txheem gasification tuaj yeem tshwm sim sai. Piv txwv li, qhov kev hloov pauv kub tam sim no yuav tshwm sim los ntawm kev hloov pauv ntawm cov pa roj carbon monoxide lossis cov khoom siv reactant. Cov lus teb ceev ceev muaj peev xwm thermocouples tuaj yeem txheeb xyuas cov kev hloov pauv no hauv ob peb lub vib nas this. Qhov no ua rau lub kaw lus tswj kom hloov pauv sai xws li dej txias lossis hloov cov oxidizing tus neeg sawv cev ntws. Lawv cov tshuaj tiv thaiv nrawm kom nres qhov kev sib tsoo uas tuaj yeem ua rau muaj kev sib tsoo thaum muaj xwm ceev hauv lub tsheb. Yog tias cov tshuaj tiv thaiv thermocouple qeeb qeeb, lub kaw lus tswj yuav tsis tuaj yeem teb sai, yog li qhov kub thiab txias yuav ua rau muaj kev phom sij txaus ntshai los ntawm qhov teev tseg.
Tsis tas li ntawd suav nrog rau hauv kev nyab xeeb dav dav ntawm cov chaw siv roj hluav taws xob yog cov thermocouples ua ke nrog cov txheej txheem kev nyab xeeb. Ib tug yuav suav lawv rau hauv lub tswb. Kev ceeb toom raug xa tawm thaum qhov kub siab tshaj qhov ntsuas kev nyab xeeb, yog li coj cov neeg ua haujlwm teb tam sim ntawd. Cov xwm txheej hnyav dua tso cai rau cov thermocouples cuam tshuam nrog cov txheej txheem kaw thaum muaj xwm txheej ceev. Yog tias qhov ntsuas kub tseem ceeb dhau mus, thev naus laus zis tuaj yeem nres qhov txheej txheem gasification tam sim kom tiv thaiv kev puas tsuaj loj. Qhov kev koom ua ke no tau lees paub tias, yuav tsum muaj kev phom sij raug txheeb xyuas, cov kauj ruam tsim nyog yuav tsum tau ua los tiv thaiv cov tub rog-hauv qhov piv txwv no, lub Hoobkas thiab nws cov neeg ua haujlwm-los ntawm kev sib txuas ntawm cov lus txib hauv kev ua tub rog.
Hauv cov ntsiab lus, kev txhim kho kev nyab xeeb hauv gasification nyob ntawm cov thee tshuaj thermocouples. Ua ke, nws qhov ntsuas kub zoo, ua haujlwm ntev, lub sijhawm ua haujlwm sai, thiab kev sib txuas nrog cov tshuab kev nyab xeeb pab tswj cov txheej txheem gasification nyob rau hauv qhov tsim nyog ciam teb. Kev tiv thaiv kev pheej hmoo ntawm cov teeb meem kub ntxhov thiab lav qhov kev noj qab haus huv ntawm cov nroj tsuag, cov neeg ua haujlwm, thiab ib puag ncig, lawv yog cov neeg saib xyuas ntawm cov txheej txheem thee gasification.
