Hydrogen yog dav siv nyob rau hauv ci hardening ntawm ntau hlau. Ob qho tib si hydrogen purity thiab humidity theem nyob rau hauv lub
gas yuav tsum tau ntsuas thiab tswj.
Cov dej noo ntau dhau tuaj yeem txo lub zog thiab zoo ntawm cov khoom tiav. Muaj ob txoj hauv kev tseem ceeb
ntawm hydrogen thauj hauv metallurgy --bulk hydrogen los ntawm lub tog raj kheej roj thiab pyrolysis ammonia. Metallurgical
txheej txheem dej ntsuas yogtseem ceeb heev, xav paub ntxiv mus saib!
Ua ntej, Ob txoj kev xa khoom muaj qhov zoo thiab qhov tsis zoo.
Ntshiab hydrogen tuaj yeem siv tau tam sim ntawd, tab sis nws yuav kim dua, thiab khaws cia ntau ntau
hydrogen rau kev siv ua rau muaj kev phom sij.
Ammonia (NH 3) yog pheej yig dua los yuav hauv ntau thiab tsis tshua muaj nplaim taws, yog li nws muaj kev nyab xeeb dua rau khaws cia hauv thaj teb.
Txawm li cas los xij, nws muaj nws tus kheej txaus ntshai: nws yog corrosive heev,
yog li cov khoom siv hauv Hoobkas thiab kev nyab xeeb ntawm tus kheej yog cov kev txhawj xeeb tseem ceeb. Txawm li cas los xij, ammonia cracking units
tam sim no yog ib txoj hauv kev ntau dua los muab ib qhotxo / hardening cua rau metallurgical
rauv. Lub dissociated ammonia yog sib tov ntawm hydrogen thiab nitrogen thiab yog hu ua "synthetic gas".
Qhov thib ob, Ammonia Cracking ua haujlwm li cas?
Lub pressurized ammonia yog rhuab kom evaporate nws. Tom qab ntawd nws tau tawg mus rau hauv nws qhov chaw,
hydrogen thiab nitrogen, los ntawm nickel catalyst ntawm akub txog li 1,000 ° C. Kev sib npaug ntawm chemical
Cov tshuaj tiv thaiv yog: 2NH 3A → N 2 + 3H 2
Vim ua kom tiav decomposition rau hauv hydrogen thiab nitrogen, tsawg heev nyob rau hauv muaj ammonia tshuav
thiab lub resulting gas yuav tsum muaj ib tug heevqis qis taw tes kub (zoo hauv qab -30 ° C). Dew point
Kev ntsuas kub xav tau kev saib xyuas tshwj xeeb, vim tias muaj ntau zaus, siab dhau lawmlos yog tsawg dhau
Dew point kub tuaj yeem cuam tshuam qhov zoo ntawm cov khoom. Ntxiv nrog rau kev lag luam metallurgical,
compressed cua tshuabyog qhov tseem ceeb tshaj rau dew point. HENGKO608 dew point transmittermuab
kev ruaj ntseg mus sij hawm ntev thiab teb sai sai rau cov av noo hloov.
HENGKO lub siab ntim tsim muaj peev xwm ua rau nws haum rau OEM thiab kev sib koom ua ke
uas xav tau lub sij hawm luv luv thiab zoo ib yam.
Lub molecular sieve absorbs qhov kawg kab ntawm uncracked ammonia tseem tam sim no nyob rau hauv cov pa. Gas tau
kuj yuav ntxiv qhuav siv ib tug rhuabregenerative dual-kem desiccant-dryer, qhov twg cov roj nws thiaj li
tawm hauv lub tshuab ziab khaub ncaws ntawm qhov kub hauv qab -65 ° Cdp thiab muajntawm 75 Vol% hydrogen thiab
25 Vol% nitrogen.
Thib peb, Synthetic gas (decomposition of ammonia) daim ntawv thov
Synthetic gases yog siv nyob rau hauv conveyer thiab tub rauv rau annealing txheej txheem nyob rau hauv txo cov cua,
xws li brazing, sintering,deoxidation thiab nitride.
Plaub, Saib xyuas cov kab ya raws hauv cov ammonia dissociated
Tsis tu ncuadew point metertuaj yeem siv online lossis chaw kuaj xyuas cov dej noo hauv huab cua ntsuas. Tsim nyog
rau kev ntsuas hauvqhov chaw uas tsis muaj kev nyab xeeb kev faib tawm. Qhov no tshwm sim hauv ntau lub qhov cub
daim ntawv thov. High ceev,Portable dew-point hygrometerrau qhov ceev ceev ntsuas ntsuas ntawm dew point
los yog noo noo cov ntsiab lus nyob rau hauv compressed cua, natural gas,quenched gas nyob rau hauv siab hloov iav, thiab ntau
lwm daim ntawv thov. Lub sensor teb sai sai rau kev hloov pauv ntawm cov av noo los ntawmqhuav kom ntub los yog ntub kom qhuav. Qhov no
txhais tau tias tsis muaj kev tos ntawm kev ntsuas thiab tus neeg teb xov tooj tuaj yeem ntsuas ntau dua hauv ib hnub.
