Kev hloov kho loj-flow 7-lub hnab lim rau kev lag luam tshuaj lom neeg, daws qhov teeb meem ntawm kev rov qab catalyst

I. Cov Teeb Meem ntawm Cov Neeg Siv Khoom: Kev Rov Qab Tau Cov Tshuaj Catalysts Muaj Nqis Thiab Cov Teeb Meem Ntawm Cov Txheej Txheem

Hauv cov txheej txheem tsim khoom ntawm nws cov khoom lag luam catalyst tseem ceeb, XX Chemical muaj ib kauj ruam tseem ceeb: tom qab ua tiav qhov kev sib xyaw, cov khoom ua kua yuav tsum tau sib cais los ntawm cov hmoov catalyst khoom kim heev thiab ua haujlwm tau zoo heev. Qhov teeb meem uas lawv ntsib yog:

• Kev ua haujlwm siab:Qhov ntim ntawm cov kua dej uas yuav tsum tau ua tiav hauv txhua pawg yog loj (ntau dua 50 cubic meters), thiab qhov ntws ntawm lub kaw lus lim dej yuav tsum ncav cuag 100 m³ / h; txwv tsis pub, nws yuav cuam tshuam rau tag nrho cov voj voog ntau lawm.
• Kev cuam tshuam siab heev:Qhov loj ntawm cov khoom me me ntawm cov tshuaj catalysts khov kho feem ntau yog nruab nrab ntawm 10 thiab 25 micrometers. Lawv yuav tsum tau raug cuam tshuam thiab rov qab tau tag nrho; txhua qhov kev poob txhais tau tias yuav poob nyiaj ntau heev.
• Cov xwm txheej ua haujlwm hnyav:Cov tshuaj tiv thaiv muaj qhov xeb me ntsis, thiab qhov kub ntawm cov txheej txheem raug tswj hwm ntawm 70-75 ° C. Cov khoom siv yuav tsum tiv taus xeb thiab muaj peev xwm tiv taus qhov kub siab.
• Kev tsim khoom siab:Cov khoom siv lim dej qub muaj peev xwm tsawg los tswj cov pa phem thiab feem ntau raug hloov pauv, ua rau muaj kev hloov pauv loj heev ntawm lub zog ntawm lub kaw lus. Nws tsis tuaj yeem ua haujlwm tas mus li ntawm 1.0 MPa ruaj khov, yog li ntawd cuam tshuam rau kev sib xws ntawm cov khoom.

Tus neeg siv khoom xav tau kev daws teeb meem lim dej muaj peev xwm siab uas ua haujlwm tau zoo, ruaj khov, thiab hloov kho tau los daws lawv cov teeb meem tshwj xeeb.

II. Peb Txoj Kev daws teeb meem uas haum rau koj

Tom qab nkag siab txog cov ntsiab lus thiab cov teeb meem ntawm tus neeg siv khoom, peb pab neeg ua haujlwm tau hais kom ua ib qho kev cai tshwj xeeb7-lub hnab limkev daws teeb meem:

Cov khoom siv tseem ceeb ua raws li tus neeg xav tau:

• Qauv:7-txheej lim dej, nrog rau thaj chaw lim dej loj, muaj peev xwm tswj tau qhov ntws ntawm 100 m³ / h tau yooj yim.
• Khoom siv plhaub:SS304 stainless hlau, ua kom muaj kev tiv thaiv corrosion zoo heev rau cov tshuaj tiv thaiv.
• Cov qauv tseem ceeb:Kev taw qhia ntws ntawm sab hauv qab mus rau sab nraud, ua ke nrog lub phaj qhia sab hauv tshwj xeeb, ua kom cov kua dej ntws sib npaug thoob plaws txhua lub hnab lim, zam kev hloov pauv, thiab siv qhov chaw lim kom zoo tshaj plaws.
• Lub zog kho tshuab:Lub plhaub tuab yog 5.0 hli, tsim tawm raws li kev tsim siab ntawm 1.6 MPa, ua kom muaj kev ua haujlwm ruaj khov mus sij hawm ntev hauv qab kev ua haujlwm siab ntawm 1.0 MPa thiab tshem tawm txhua yam kev pheej hmoo kev nyab xeeb.
• Kev kho qhov chaw:Cov phab ntsa sab hauv thiab sab nraud raug kho nrog xuab zeb, uas ua rau muaj kev tiv thaiv xeb thiab ua rau kev ntxuav thiab kev saib xyuas yooj yim dua.

Kev sib phim meej ntawm kev lim dej raug:
Peb pom zoo thiab muab cov hnab lim polyester (PES) uas muaj qhov tseeb siab nrog 15-micron. Cov khoom siv no muaj kev tiv taus kub zoo heev thiab kev ruaj khov tshuaj lom neeg, tuaj yeem ntes tau txhua yam khoom me me, thiab ua kom muaj kev lim dej zoo heev thiab muaj peev xwm lim tau zoo heev.

Kev sib koom ua ke thiab kev tsim kho yooj yim:
Qhov kev xa khoom thiab xa tawm raug teeb tsa raws li cov kav dej ntawm tus neeg siv khoom, kho kom haum rau tus qauv flange DN250 (ISO), ua tiav kev sib txuas tsis muaj teeb meem.
Nrog rau lub hau kaw hydraulic uas qhib sai, ib tus neeg ua haujlwm tuaj yeem ua tiav qhov hloov pauv sai ntawm 7 lub hnab lim hauv 10 feeb, txo qhov sijhawm tsis ua haujlwm.

III. Cov txiaj ntsig ntawm daim ntawv thov thiab tus nqi ntawm cov neeg siv khoom

Txij li thaum siv cov lim dej no los ua haujlwm, tau txais cov txiaj ntsig zoo kawg li:

• Kev txhim kho tseem ceeb hauv kev ua haujlwm zoo:Qhov ceev ntawm kev lim dej ua tau raws li qhov xav tau ntawm 100 m³ / h, thiab lub sijhawm ua tiav rau ib pawg tau raug txo los ntawm 40%, ua rau muaj peev xwm tsim khoom ntau ntxiv.
• Txo tus nqi tseem ceeb:Tus nqi rov qab los ntawm cov catalyst tshaj 99.8%, thiab nws pab cov neeg siv khoom txuag tau kaum txhiab yuan hauv kev poob txhua xyoo. Tib lub sijhawm, vim nws muaj peev xwm nqa cov av loj, lub voj voog hloov pauv ntawm lub hnab lim tau ntev dua peb zaug, yog li txo cov nqi ntawm cov khoom siv.
• Kev ua haujlwm ruaj khov thiab txhim khu kev qha:Cov khoom siv ua haujlwm tau zoo nyob rau hauv qhov kub thiab txias ntawm 1.0 MPa thiab 75 ° C, nrog rau qhov hloov pauv siab tsawg kawg nkaus, ua kom ntseeg tau tias qhov khoom zoo thiab kev nyab xeeb ntawm kev tsim khoom ruaj khov.
• Kev saib xyuas yooj yim heev:Lub hau qhib sai thiab sab hauv, hauv qab tawm qauv ua rau cov txheej txheem txij nkawm sai thiab yooj yim, txo qhov kev siv zog ntawm cov neeg ua haujlwm.

Kev tshuaj xyuas los ntawm cov neeg siv khoom:

"Thaum xub thawj, peb tsuas yog nrhiav ib lub lim dej ib txwm muaj xwb. Tiam sis lawv pab neeg ua haujlwm tau qhia txog kev ua haujlwm zoo tiag tiag. Lawv nkag siab zoo txog peb cov teeb meem ntawm cov txheej txheem thiab muab kev daws teeb meem rau peb. Lub lim dej 7-lub hnab no tsis yog tsuas yog ua tau raws li cov kev cai xwb, tab sis kuj daws tau tag nrho peb cov teeb meem kev tsim khoom thiab cov teeb meem nqi. Qhov no yog kev koom tes ua tiav zoo heev!"
