Daim ntawv thov ntawm Gas Detector hauv Paper Mill
Cov ntawv mills muaj feem cuam tshuam nrog peb lub neej, thiab cov txiaj ntsig kev lag luam uas lawv coj los kuj zoo siab heev. Txawm li cas los xij, cov ntawv zeb tseem tsim cov roj pov tseg ntau, uas muaj kev cuam tshuam loj rau kev nyab xeeb ntawm cov neeg ua haujlwm thiab ib puag ncig.
Paper pulp mill yog cov txheej txheem tsim tshuaj nrog cov nroj tsuag fiber ntau li cov khoom siv raw, tab sis nyob rau hauv txhua qhov txuas ntawm nws cov khoom, vim muaj ntau yam kev cuam tshuam ntawm lub cev thiab tshuaj lom neeg thiab cov roj combustion, ntau cov pa roj yuav raug tso tawm, ua rau muaj kuab paug hauv huab cua.
Cov khib nyiab tseem ceeb tso tawm rau hauv cov huab cua los ntawm cov ntawv thiab cov tshuab pulp muaj xws li sulfur compounds, chlorine compounds, nitrogen compounds, inorganic plua plav, organic gases, thiab lwm yam. Muaj ob lub ntsiab ntawm sulfur compound dissipation: ib qho yog malodorous gases, xws li hydrogen sulfide. , methyl sulfide, dimethyl sulfide, thiab dimethyl disulfide. Lub hauv paus ntsiab lus ntawm cov roj no yog pulping los ntawm kraft txoj kev thiab alkali rov qab txheej txheem; Lwm hom yog sulfur oxide SOX, feem ntau yog los ntawm acid sulfite pulping txheej txheem, tab sis kuj los ntawm nruab nrab sulfite thiab bisulfite mus rau txawv degrees.
Lub emission ntawm chlorine tebchaw nyob rau hauv daim ntawv mills yog me me, feem ntau CL2 thiab CLO2. Lub dissipation ntawm chlorine tebchaw yog "diffusion type", uas yog, feem ntau tsis muaj qhov tshwj xeeb qhov chaw dissipation, thiab yog li diffuses los ntawm cia tank, ntxhua khaub ncaws, trench, thiab lwm yam.
Nitrogen oxides tuaj yeem tsim los ntawm txhua qhov txheej txheem combustion.
Kev tso tawm ntawm cov plua plav inorganic feem ntau yog los ntawm cov boilers rov qab, roj (roj los yog thee) boilers thiab txiv qaub kilns. Cov plua plav no feem ntau yog sulfates thiab carbonates.
Cov khoom siv hluav taws xob tsis zoo feem ntau yog los ntawm kev npaj cov khoom siv raw, xws li qhuav debarking nruas ntawm cov cav, qhuav debarking ntawm bagasse, thiab ua thiab purification ntawm nyom raw cov ntaub ntawv, xws li tsis-condensable gases los ntawm depressurization ntawm ua noj ua haus thiab evaporation ntawm pov tseg kua.
Tsis tas li ntawd, cov sludge sedimentation tso tsheb hlau luam tsim los ntawm papermaking kuj yuav tsim tsw vim fermentation.
Cov hom thiab kev phom sij ntawm cov pa khib nyiab uas tsim los ntawm cov ntawv zeb yog qhov hnyav. Nyob rau hauv xyoo tas los no, cov xwm txheej tshwm sim los ntawm kev ua pa lom ntawm cov neeg ua haujlwm hauv ntawv zeb tau tshwm sim ntau zaus. Cov laj thawj tseem ceeb ntawm cov neeg ua hauj lwm lom raug xwm txheej tshwm sim los ntawm cov pa khib nyiab hauv cov ntawv mills yog raws li hauv qab no:
1. Muaj kev nkag siab yuam kev hauv kev txheeb xyuas qhov chaw txwv.
Cov ntawv mills koom nrog cov chaw ua haujlwm uas muaj qhov chaw tsawg, xws li tswj cov pas dej thiab cov chaw kho dej phwj. Qee cov neeg ntseeg tias cov pas dej qhib no tsis nyob hauv qhov chaw txwv, thiab yuav tsis ua rau cov neeg ua haujlwm lom, yog li lawv so lawv cov kev ceev faj.
2. Kev ua xua thiab ua xua yog qhov tseem ceeb ntawm kev ua haujlwm raug mob hauv qhov chaw tsawg ntawm cov ntawv zeb.
Nyob rau hauv cov txheej txheem ntawm dredging, tu, tshuaj xyuas thiab tu, nws yog ib qho yooj yim heev ua rau lom los ntawm hydrogen sulfide, carbon monoxide thiab lwm yam tshuaj lom thiab teeb meem gases thiab asphyxiation xwm txheej vim tsis muaj oxygen. Yog hais tias lub koom haum koom nrog hauv qhov xwm txheej tsis tau ua tiav kev txheeb xyuas thiab kev ntsuam xyuas ntawm kev pheej hmoo ntawm kev ua haujlwm hauv qhov chaw txwv, tsis tau ua raws li kev pom zoo ua haujlwm txaus ntshai, tsis ua raws li cov txheej txheem ua haujlwm ntawm "ventilate ua ntej, tom qab ntawd tshuaj xyuas, thiab tom qab ntawd ua haujlwm", thiab tsis tau lees paub qhov kev nyab xeeb xws li kev tshuaj xyuas, kev tiv thaiv, thiab kev saib xyuas. Kev ua haujlwm raws li qhov xwm txheej tuaj yeem ua rau muaj xwm txheej.
3. Kev cawm qhov muag tsis pom kev ua rau muaj neeg tuag coob zuj zus tuaj.
Vim tsis muaj kev paub txog xwm txheej ceev thiab kev cawm tus kheej thiab kev sib nrig sib pab kev muaj peev xwm ntawm chav sib tsoo thiab cov neeg ua haujlwm nyob rau hauv qhov chaw, nrog rau qhov tsis muaj cov cuab yeej tiv thaiv tus kheej thiab cov khoom siv thaum muaj xwm ceev, lawv tau cawm qhov muag tsis pom kev yam tsis tau qhia meej txog cov xwm txheej txaus ntshai thiab noj. txhim khu kev tiv thaiv kev ntsuas, ua rau muaj kev raug mob ntau ntxiv.
Yog li ntawd, kom muaj kev nyab xeeb vim li cas, cov ntawv zeb yuav tsum tau ua txoj haujlwm zoo ntawm kev saib xyuas cov pa phem thiab cov pa phem, teeb tsa cov khoom siv roj, thiab saib xyuas cov ntsiab lus ntawm cov pa phem thiab cov pa phem hauv cov huab cua hauv lub sijhawm tiag tiag kom ntseeg tau tias lub neej ntawm cov neeg ua haujlwm tsis raug ua txhaum cai. .
Gas detectors feem ntau siv nyob rau hauv daim ntawv mills muaj xws li flammable gas detection tswb, hydrogen sulfide gas detectors, oxygen detectors, hydrogen chloride gas detection tswb, thiab lwm yam. Cov neeg ua hauj lwm tswj yuav tsum txheeb xyuas cov txheej txheem uas muaj roj to raws li qhov teeb meem ntawm lub Hoobkas cheeb tsam, thiab nruab. Cov khoom siv hluav taws xob sib txuas ntawm qhov chaw tsim nyog kom ntseeg tau tias muaj kev nyab xeeb ntawm cov pa roj hauv thaj tsam ntawm lub Hoobkas.
