Nyob rau hauv tus flue gas desulfurization system ntawm lub zog cog qoob loo, kev soj ntsuam qhov tseeb yog ib qho tseem ceeb ntawm cov haujlwm ruaj khov thiab ua haujlwm tau zoo ntawm cov kab ke. Raws li lub siab-precision kub ntsuas ntaus ntawv, wrre2-291thermocoupleUa si lub luag haujlwm tsis tseem ceeb hauv qhov ntsuas kub ntawm qhov ntsuas kub ntawm lub zog cog qoob loo, thiab tiv thaiv cov roj fluulfuration tag nrho.

I. OVERVIEW FLUE GAS DESULFURFURDONATIONY THIAB LUB TSEEM CEEB NTAWM NTSHAV

Flue Gas Desulfurization System yog siv los tshem cov sulphur dioxide los ntawm hlawv cov roj ntsha hauv cov nroj tsuag hluav taws xob hauv ib puag ncig. Cov txheej txheem kev ua kom muaj kev txhaj tshuaj tiv thaiv av, thiab lwm yam.

Piv txwv li, hauv cov txheej txheem limone-gypsum txoj kev, cov tshuaj tiv thaiv ntawm limestone slurry thiab sulfur dioxide nyob rau hauv flue roj yuav tsum tau nqa tawm hauv qhov ntsuas kub tshwj xeeb. Kev kub dhau heev yuav txo cov solubility ntawm limestone, cuam tshuam rau cov tshuaj tiv thaiv tus nqi thiab desulfurization efficiency; Tsawg dhau qhov kub yuav ua rau calcium sulfite nyob rau hauv slurry yooj yim rau crystallize thiab nag lossis daus, thiab nce tus txij nkawm cov cuab yeej siv. Ib qho ntxiv, cov cuab yeej siv thiab cov raj dej thiab cov ntaub ntawv hauv cov txheej txheem desulfuronization yuav muaj cov khoom siv lub cev sib txawv thiab tshuaj lom neeg nyob hauv ib puag ncig. Cov kev hloov pauv kub tam sim no yuav ua rau thermal kev ntxhov siab ntawm cov cuab yeej, thiab muaj mob hnyav, puas tsuaj rau cov khoom siv.

Ii. Cov yam ntxwv thiab cov hauv paus ntsiab lus ntawm BRE2-291 thermocouple

(I) cov yam ntxwv

1. Muaj qhov tseeb

Lub wre2-291thermocoupleMuaj peev xwm raug ntsuas ntsuas qhov kub thiab txias hauv qhov raug ntawm [X] degrees Celsius, uas pab kom raug kom raug qhov kub hauv lub hauv paus.

2. Zoo ruaj khov

Nws muaj cov tshuaj ruaj khov zoo thiab tuaj yeem ua haujlwm stably rau lub sijhawm ntev hauv cov tshuaj uas yog cov tshuaj uas desulfuration, thiab tsis yooj yim cuam tshuam los ntawm kev xeb.

3. Nej cov ntsuas dav ntau

Qhov ntsuas kub ntawm [qhov kub thiab kub tau ntsuas] tuaj yeem ntsuas kom tau raws li kev soj ntsuam qhov kub thiab txias ntawm ntau qhov chaw desulfurization.

(II) txoj ntsiab cai

Thermocoples ua haujlwm raws li cov kev qhia zoo. Thaum muaj qhov sib txawv ntawm qhov sib txawv ntawm ob tus neeg sib txawv lossis cov semiconductors, hluav taws xob hluav taws xob yuav tsim tawm hauv lub voj. Lub wre2-291 thermocouple siv ib thickocouple-chromium-tooj-chromium-constantan) hloov ntsuas kub ntawm qhov kub thiab txias.

III. Tshwj xeeb tiv thaiv kev tiv thaiv lub luag haujlwm hauv kev ua haujlwm desulfurization

(Kuv) cov tshuaj tiv thaiv kev kub

1. Limestone slurry cov tshuaj tiv thaiv tank

Nyob rau hauv lub limestone slurry cov tshuaj tiv thaiv tank, lub rre2-291 thermocouple ntsuas qhov kub thiab txias hauv lub sijhawm tiag tiag. Yog tias qhov kub thiab txias deviates ntawm cov tshuaj tiv thaiv kub zoo (feem ntau yog nyob rau hauv qhov ntsuas cua txias kom ntseeg tau tias qhov kev tiv thaiv dej txias kom ntseeg tau tias cov tshuaj tiv thaiv dej txias kom ntseeg tau tias muaj peev xwm txuas ntxiv mus tau yooj yim thiab ua kom cov khoom siv hluav taws xob tau zoo.

2. Gypsum crystallization txheej txheem

Nyob rau hauv Gypsum Crystallization txheej txheem, qhov yog qhov tseem ceeb yog tus yuam sij rau kev tsim cov gypsal siab gypsum thiab tsis muaj ntau ntawm gypsum nplai. Tom qab Thermocouple ntsuas qhov kub thiab txias hloov, nws tuaj yeem tswj cov dej kub thiab lwm yam cuam tshuam ntawm crystallizer kom tiv thaiv cov teeb meem gypsum uas tshwm sim los ntawm kev tsis txaus ntseeg.

(II) Kev Tiv Thaiv Khoom Siv

1. Kev tiv thaiv ntawm cov raj xa dej thiab li qub

Muaj ntau tus lej ntawm cov nplais ntawm cov nplais thiab cov li qub nyob hauv qhov system desulfurization. Thaum lub wre2-291 thermocouple pom kev hloov pauv sai, xws li kev cuam tshuam rau cov raj xa dej lossis kev cuam tshuam nrog kev cuam tshuam nrog kev sib cuam tshuam lossis kev puas tsuaj vim yog kev ntxhov siab.

2. Kev tiv thaiv ntawm corrosion-resistant khoom siv

Ntau cov cuab yeej siv hauv Desulfurization system, xws li cov yees nqus dej, cov kiv cua oxidation, thiab lwm yam. Cov ntaub ntawv kub tau soj ntsuam los ntawm Thermocouple tuaj yeem pab tswj cov kev ua haujlwm ntawm cov khoom siv kom tsis txhob muaj kev txom nyem cov khoom siv kev xeb vim muaj ntau kub.

(Iii) tiv thaiv kev ntsuas thiab thaiv

1. Cov xa hluav taws xob ntsuas kev soj ntsuam

Los ntawm kev soj ntsuam qhov ntsuas kub thiab txias hauv raj dej, qhov thermocouple tuaj yeem pom qhov ntsuas cov khoom ua ntej ua ntej cov kev hloov pauv kub. Piv txwv li, hauv cov cheeb tsam tau txhawm rau txhawm rau ntsuas thiab li qub, nws txhais tau tias cov tshuaj uas muaj qhov tsis txaus ntseeg, yog li lawv tuaj yeem raug ntxuav kom huv sijhawm.

2. Inlet Flue Roj Kub Saib Xyuas

Rau cov roj flue gas nkag mus rau cov plua plav desulfuration, yog tias nws qhov kub thiab txias heev, nws yuav ua rau lub nra hnyav, thiab kuj tseem yuav ua rau muaj kev sib ntsuas ntawm qhov hluav taws xob ntawm qhov nqus dej ntawm qhov nqus dej ntawm qhov nqus dej ntawm qhov nqus dej ntawm qhov nqus dej ntawm qhov nqus dej. Kev soj ntsuam ntawm inlet flue roj kub los ntawm lub wre2-291 thermocouple pab txias kom txias cov roj flue flureatment thiab txo txoj kev pheej hmoo ntawm kev sib cav thiab thaiv.

IV. Txhaum kev kuaj mob thiab ceeb toom ntxov

Lub wre2-291 thermocouple kuj tseem siv tau los ua cov cuab yeej tseem ceeb rau kev ua txhaum. Yog hais tias qhov ntsuas kub ntawm qee qhov kev soj ntsuam taw tes tseem muaj teeb meem, nws yuav qhia tau tias muaj teeb meem nrog qhov tsis txaus ntseeg, kev nqus hluav taws xob sab hauv lossis cua sov. Nws tuaj yeem xa cov cim qhia ntxov rau cov tswj kev tswj hwm hauv lub sijhawm, yog li cov neeg ua haujlwm tuaj yeem ntsuas kho tau ntau dua los kho thiab zam qhov teeb meem ntxiv.
