SLDF2085 Ultrasonic Flow Meter: Ib Tus Qauv Tshiab rau Emulsified Medium Measurement -Kev Ua Tau Zoo hauv Ethylene Plant's DN600 Roj- Kev Ntsuas Dej Sib xyaw

 

1. Cov ntsiab lus mob hauv kev lag luam: Lub fwj tseem ceeb hauv DN600 roj- ntsuas dej sib tov

 

Hauv kev ua haujlwm ntawm ethylene, DN600 roj- cov kav dej sib xyaw ua haujlwm yog qhov tseem ceeb ntawm kev sib txuas ntawm quench system thiab chav sib cais. Nws qhov kev ntsuas qhov tseeb ncaj qha cuam tshuam rau cov roj- dej sib cais kev ua haujlwm thiab kev tswj kev siv hluav taws xob. Txawm li cas los xij, cov kev ua haujlwm nyuaj hauv qhov xwm txheej no tau ntev ua cov ntsuas dej ntws tsis zoo:

Cov yam ntxwv nruab nrab: Cov roj- dej sib tov yog dynamically emulsified, nrog cov roj theem sib piv ntawm 15% thiab 60%, thiab muaj cov kab mob coke hmoov (particle loj tsawg dua lossis sib npaug li 0.5mm). Lub sij hawm ib txwm muaj- qhov sib txawv flowmeter yog qhov ua rau muaj teeb meem cuam tshuam vim kev cuam tshuam acoustic tshaj tawm, ua rau kev ntsuas qhov sib txawv tshaj ± 5%.

Kev hloov pauv ntau zaus hauv kev ua haujlwm: nruab nrab kub 45-95 degree, siab 0.3-0.5MPaG, ntws tus nqi nyob rau hauv thaj tsam ntawm 800-2200m³ / h fluctuates hnyav, cov pa flowmeter yog qhov nyuaj rau hloov mus rau cov kev xav tau ntawm ntau yam thiab siab precision;

Kev teeb tsa thiab kev saib xyuas cov teeb meem: Cov ntsuas ntsuas dej tsis txaus yuav tsum tau txiav DN600 loj - txoj kab nruab nrab, ua rau ntau tshaj 72- teev kaw rau kev rov ua dua thiab kev poob nyiaj txiag tseem ceeb. Sab nraud-mounted flow meters (piv txwv li, qauv) yog qhov ua rau cov kav dej scaling thiab cov phab ntsa tsis sib xws, nrog qhov nruab nrab ntawm 2 lub hlis ua tsis tiav. Kev tu cov txheej txheem suav nrog cov roj tso tawm thiab tso dej phwj tuaj tsis yog tsuas yog ua phem rau ib puag ncig xwb tab sis kuj ua rau muaj kev nyab xeeb.

Kev tawg- cov ntaub ntawv pov thawj yog nruj: cov raj xa dej nyob rau hauv qhov chaw txaus ntshai ntawm thaj tsam 20, uas ua rau muaj kev xav tau siab rau kev tawg- qib pov thawj thiab kev tiv thaiv kev ua haujlwm ntawm cov flowmeter, thiab cov cuab yeej zoo tib yam nyuaj ua kom tau raws li cov qauv.

Cov teeb meem no ua rau cov kua theem ntawm cov cuab yeej sib cais ntauwd hloov pauv ± 150mm, thiab qhov ntau npaum li cas ntawm tus neeg sawv cev kom pov tseg 10% -15%, uas tau dhau los ua lub hauv paus tseem ceeb txwv tsis pub txo tus nqi thiab kev nce qib ntawm cov lag luam petrochemical.

 

2. Cov Tswv Yim Zoo Tshaj Plaws: Targeted Technological Innovation ntawm SLDF2085

 

Txhawm rau daws qhov teeb meem kev ntsuas ntawm DN600 roj- dej sib tov, SLDF2085Ultrasonic flowmeterxa ib qho kev daws teeb meem los ntawm qhov xwm txheej- raws li kev hloov kho.

(1) Cov cuab yeej technology tseem ceeb

Emulsion nruab nrab- tshwj xeeb algorithm: Raws li SLDF2085 bidirectional lub sij hawm sib txawv thev naus laus zis, tus qauv dynamic ntawm "roj theem piv- suab nrawm them nyiaj" yog tsim los hloov kho kom hloov mus rau qhov hloov pauv ntawm 15% -60% roj theem piv, thiab ntsuas qhov tseeb yog qhov ruaj khov ntawm FS solving teeb liab ± 1. nruab nrab;

Broadband anti-kev cuam tshuam tsim: 0.3-1.8MHz Tag Nrho-band zaus scanning, ntse txheeb xyuas cov suab nrov thiab cov kav dej scaling cuam tshuam los ntawm cov hmoov hmoov, teeb liab-rau- suab nrov piv tau nce mus rau ntau tshaj 30dB, ruaj khov ntsuas nyob rau hauv qhov ntau ntawm 0.3 flow rates thiab flow rates. 10m / s;

Qhov zoo ntawm tsis yog -invasive installation: Lub clamp- ntawm kev tsim tshem tawm qhov yuav tsum tau ua kom puas DN600 cov kav dej. Nws txo cov kev xav tau ntawm cov yeeb nkab ncaj nraim ntawm Ntau dua lossis sib npaug rau 15D sab sauv thiab Ntau dua lossis sib npaug rau 8D qis qis, ua kom lub sijhawm tsim kho kom luv rau 2 teev. Lub kaw lus tuaj yeem siv tau thaum lub sijhawm tu ib ntus, zam kev poob qis.

Kev tiv thaiv kev nyab xeeb siab tshaj: Exia II CT4 nta kev tawg- pov thawj ntsuas nrog IP67 tiv thaiv, muaj peev xwm tiv taus qhov kub ntawm 45℃txog 95℃thiab 0.3-0.5MPaG siab. Nws tau ua tiav nrog Zone 20 qhov chaw muaj kev phom sij, thiab nws cov khoom siv tsis muaj kev siv tshuab txuas ntxiv cov khoom siv lub neej mus rau ntau tshaj 10 xyoo.

(2) DN600 scenario-kev teeb tsa tshwj xeeb

Kev xaiv Sensor: Lub siab- kub dual-sensor configuration (Model: CP20JB-1MHz-H) nrog 1MHz zaus, sib xws nrog DN600 carbon steel kav (phab ntsa tuab 14.2mm) ua haujlwm hauv-20 txog 210℃. Redundant configuration ua kom cov teeb liab stability.

Coupling tus neeg saib xyuas kev sib raug zoo: Lub siab - kub resistant khoom coupling tus neeg sawv cev (ua siab ntev rau Tsawg dua los yog sib npaug li 150 degree) yog siv los xyuas kom meej haum ntawm lub sensor thiab cov kav dej ntawm 95 degree, tsis muaj teeb liab attenuation thaum kis tau tus mob.

Kev Muaj Peev Xwm Kev Sib Txuas Lus: Txhawb 4-20mA cov zis tam sim no thiab HART / Modbus raws tu qauv, ua kom muaj kev sib txuas tsis sib haum xeeb nrog lub ntsiab DCS xws li Siemens thiab Yokogawa. Nrog cov ntaub ntawv xa tawm latency Tsawg dua lossis sib npaug li 0.8s, nws ua tau raws li lub sijhawm tswj hwm.

 

3. Kev Ua Tau Zoo: Daim Ntawv Thov Case ntawm ethylene Plant No.3 hauv Petrochemical Cog

 

(1) Daim ntawv thov txheej txheem

Daim ntawv thov scenario: A DN600 roj- dej sib tov pipeline rau No.3 ethylene chav tsev ntawm petrochemical cog (15m ntawm cov roj- dej sib cais ntau qhov hluav taws xob).
