Kev tshawb nrhiav ntau yam ntawm hydrogen sulfide gas detector tsuas yog nyob ntawm nws lub hom phiaj tsim, hom sensor (electrochemical, catalytic combustion, semiconductor, optical, thiab lwm yam) thiab daim ntawv thov scenarios (kev nyab xeeb ntawm tus kheej, kev saib xyuas hauv cheeb tsam, kev tswj cov txheej txheem, thiab lwm yam). Cov hauv qab no yog cov kev faib ua feem ntau ntawm kev tshawb nrhiav ntau yam:
1. Tsawg concentration ntau (ppm qib - qhov chaw ib lab):
Ntau yam: 0ppm txog 100ppm lossis 0ppm txog 200ppm.
Daim Ntawv Thov: Qhov no yog qhov ntau tshaj plaws, siv rau cov neeg ua haujlwm kev tiv thaiv kev nyab xeeb thiab kev saib xyuas ib puag ncig hauv chaw ua haujlwm.
Tswb Tswb: Lub tswb qis feem ntau yog teem rau ntawm 5-10 ppm, thiab lub tswb nrov yog teem rau ntawm 10-20 ppm.
Sensor: Feem ntau siv electrochemical sensors, raws li lawv muaj siab rhiab heev rau tsawg concentrations H₂S, zoo selectivity thiab tsawg zog noj (tsim rau portable instruments).
2. Medium concentration range (ppm qib):
Ntau yam: 0 ppm txog 500 ppm lossis 0 ppm txog 1000 ppm.
Daim Ntawv Thov: Nws yog siv rau kev saib xyuas thaj chaw uas tej zaum yuav muaj kev pheej hmoo ntawm kev xau ntawm qhov siab, xws li saib xyuas qhov nkag ntawm qhov chaw kaw, roj thiab roj cov chaw tsim khoom, cov roj refineries, cov dej phwj tuaj kho, cov nroj tsuag tshuaj thiab lwm qhov chaw tshwj xeeb. Nws kuj yog siv nyob rau hauv qee qhov portable detectors uas xav tau kev pab ntau dua.
Cov ntsiab lus tseem ceeb: Electrochemical sensors kuj tseem tuaj yeem npog qhov no, tab sis thaum mus txog qhov txwv siab, qhov tseeb yuav poob qis lossis yuav tsum tau tsim tshwj xeeb sensor.
3.H2S tus kheej roj saib xyuas
Portable hydrogen sulfide detector, muaj peev xwm tsis tu ncua kuaj xyuas cov pa tawm ntawm hydrogen sulfide gas hauv chaw ua haujlwm. Lub hydrogen sulfide detector ntsuas roj concentration los ntawm ntuj diffusion thiab txais yuav txawv teb electrochemical sensors, featuring zoo heev rhiab heev thiab zoo repeatability. Lub tshuab kuaj xyuas hydrogen sulfide txais kev kos micro- tswj thev naus laus zis, nrog kev ua haujlwm yooj yim, ua tiav cov haujlwm thiab kev ntseeg siab. Lub casing ntawm lub ntes yog ua los ntawm siab - muaj zog engineering cov ntaub ntawv thiab composite elastic cov ntaub ntawv, featuring siab zog thiab zoo txhais tes.
4. Pump suction hom hydrogen sulfide ntes
Lub twj tso kua mis suction hom hydrogen sulfide ntes tau txais lub twj tso kua mis sab hauv, uas tuaj yeem ntes cov concentration ntawm hydrogen sulfide sai sai hauv qhov chaw ua haujlwm. Lub twj tso kua mis nqus hom hydrogen sulfide ntes tau txais cov khoom siv hluav taws xob txawv teb chaws, muaj lub vijtsam loj loj LCD thiab lub suab nrov thiab pom kev ceeb toom, kom ntseeg tau tias nws tuaj yeem ntes cov pa phem thiab ceeb toom cov neeg ua haujlwm kom tiv thaiv kev tiv thaiv txawm tias nyob hauv qhov chaw ua haujlwm tsis zoo.
5. Online hydrogen sulfide nrhiav lub tswb
Lub tswb ntsuas hydrogen sulfide online muaj lub tswb ntsuas hluav taws xob thiab lub ntsuas hluav taws xob ruaj khov hydrogen sulfide. Lub tswb ntsuas hluav taws xob tuaj yeem muab tso rau hauv chav ua haujlwm los saib xyuas thiab tswj txhua qhov chaw saib xyuas. Lub hydrogen sulfide detector yog ntsia rau ntawm qhov chaw uas cov pa roj feem ntau yuav xau, thiab nws cov ntsiab lus tseem ceeb yog cov roj sensor. Lub hydrogen sulfide detector hloov cov hydrogen sulfide concentration pom los ntawm lub sensor mus rau hauv lub teeb liab hluav taws xob, uas yog kis los ntawm ib tug cable mus rau lub gas detection tswb controller. Qhov siab dua cov roj concentration, cov teeb liab hluav taws xob muaj zog dua. Thaum cov roj concentration nce mus txog lossis dhau lub tswb ceeb toom los ntawm lub tswb ntsuas, lub ntsuas roj ntsuas lub tswb yuav teeb tsa lub tswb thiab tuaj yeem pib cov khoom siv sab nraud xws li solenoid li qub thiab cov kiv cua tso tawm kom tshem tawm cov kev phom sij. Lub tswb ntsuas hydrogen sulfide online tau siv dav hauv ib puag ncig xws li roj av, tshuaj lom neeg engineering, metallurgy, fais fab, thee mines, thiab dej nroj tsuag, tiv thaiv qhov tshwm sim ntawm kev tawg.
