Yuav ua li cas kom muaj kev nyab xeeb ntawm cov tshuaj Leak hauv PTFE Thaum tshav kub kub Exchanger

tus neeg teb xov tooj saib lub siab poob ntawm qhov hluav taws xob sab, tsis muaj xim dej txias. Muaj cov xau hauv PTFE cov khoom siv hluav taws xob thiab cov txheej txheem corrosive kua tau nkag mus rau hauv cov khoom siv hluav taws xob. Ua kom sai, cov lus teb meej meej tiv thaiv kev puas tsuaj loj thiab tiv thaiv cov neeg ua haujlwm. Nov yog qhov koj yuav tsum ua.
Kev xau yog qhov xwm txheej ceev tsis yog lub sijhawm rau kev daws teeb meem - kaw thawj zaug kuaj thib ob. PTFE heat exchanger leaks feem ntau tshwm sim ntawm gasketed flange pob qij txha, ntawm lub raj - mus rau -tubesheet seals qhov twg lub liner ntsib cov hlau, los yog los ntawm cov pob txha uas tsim nyob rau hauv PTFE hlab lawv tus kheej vim hais tias rov qab thermal lossis mechanical stress. Lub liner yog chemically inert tab sis mechanically mos; Txawm tias ib lub pinhole tuaj yeem tso cai rau cov txheej txheem nruj kom txav mus rau hauv qhov chaw siv hluav taws xob, lossis rov ua dua, paug cov dej txias, chav condensate lossis thermal roj circuits. Cov lus teb raws sij hawm thiab tsim nyog yuav pab txo qhov raug, txwv tsis pub tso tawm thiab tshuaj xyuas yog tias cov khoom sib pauv tuaj yeem rov ua haujlwm lossis hloov pauv.
Tag nrho cov ntws sai sai yog tias xav tias muaj qhov xau, los ntawm kev poob siab, muaj xim tsis zoo, ntxhiab tsw txawv lossis cov kua dej loj hlob hauv qhov ntws tawm - nres. Kaw cov txheej txheem inlet thiab tso zis thaiv li qub thiab tom qab ntawd kaw cov khoom siv hluav taws xob - sab li qub. Qhov no cais cov exchanger thiab tiv thaiv kev sib tov ntawm cov kua dej ntxiv. nrog rau chav tsev cais qhov cua siab ruaj ntseg. Direct txhua qhov tso pa tawm mus rau lub tshuab ntxhua khaub ncaws, flare, lossis kaw kaw, tsis txhob mus rau qhov chaw. Tsis txhob qhib lub qhov tso pa tawm yam tsis tau kuaj xyuas tias cov dej ntim hauv qab tau npaj. Yooj yim rau ntawm lub siab ntawm ob sab kom koj tsis txhob muaj qhov nrawm nrawm uas yuav ua rau qhov loj ntawm cov xau channel. Tsis txhob pib tso dej kom txog thaum lub siab poob mus rau xoom gauge.
Kev hnav PPE txoj cai tsis yog xaiv tau - nws yog qhov sib txawv ntawm qhov tsis nco qab thiab raug mob. Mus rau qhov sib pauv nrog Daim Ntawv Qhia Kev Nyab Xeeb (SDS) rau cov txheej txheem tshwj xeeb. Yam tsawg kawg nkaus, hnav cov hnab looj tes tiv thaiv kab mob, cov tsom iav tiv thaiv kab mob, daim npog ntsej muag tag nrho, cov tshuaj tiv thaiv kab mob los yog khaub ncaws, thiab steel- cov khau khiab khau. Yog hais tias cov kua yog volatile los yog muaj kev phom sij, hnav lub tshuab ua pa los yog tus kheej - muaj cov cuab yeej ua pa. Txhua tus neeg ua haujlwm nyob rau thaj tsam tam sim no kuj yuav tsum tau tiv thaiv kom raug ua ntej ua haujlwm ntxiv.
Nres qhov xau los ntawm kev sib kis. Muab cov mats absorbent, booms los yog ib ntus dikes nyob ib ncig ntawm flanges thiab drains. Cov kua dej yuav tsum tau muab tso rau hauv chav kawm muaj kev phom sij uas siv cov khoom siv los yog cov tshuaj muaj cai tso cai - cov thawv ntim khoom. Kev nce qib hauv cov kua hauv lub plhaub- sab ntws (los yog kev siv hluav taws xob- sab ntws) ntawm lub plhaub- thiab - tube exchangers yog cov tsos mob ntawm lub raj xau. Tam sim ntawd ntes thiab tshuaj xyuas cov kua dej no kom paub tseeb tias koj qhov chaw. Khaws cov ntaub ntawv ntawm lub hauv paus siab txo qhov pom thaum lub sijhawm ua haujlwm. Ib qho kev hloov pauv tsis txaus ntseeg tam sim ntawd feem ntau yog thawj qhov qhia tau hais tias qhov xau tau pib.
Thaum lub exchanger yog cais, emptied thiab muaj, pinpoint lub xau raws nraim. Kev soj ntsuam pom ntawm txhua qhov siv tau flanges thiab gaskets. Siv cov tshuaj xab npum thiab dej rau cov pob qij txha uas muaj qhov sib cais nyob rau hauv ib qho kev sib haum xeeb zoo (feem ntau yog 0.5 - 1 bar). Npuas txhais tau tias gasket leaks. Yog tias tsis pom qhov xau sab nraud, ua rau kev sim sab hauv. Tshem tawm ob sab tag nrho. Siab- kuaj qhov xav tias yuav tawm sab nraud- feem ntau yog cov txheej txheem sab ua ntej- nrog cov huab cua huv lossis nitrogen. Yog tias koj muaj lub raj xau, cais lub raj sab thiab muab tso rau hauv cov khoom sib hloov hauv dej (piv txwv tias cov kua dej seem tsis muaj kev phom sij thiab qhov kev sim tau ua nyob rau hauv ib cheeb tsam tswj kav) los yog siv lub helium leak detector kom rhiab heev. Lub raj xaim tuaj yeem ua rau xim xim- nkag mus kuaj kom pom cov kab nrib pleb ntawm cov kab ntawv{14}} mus rau - cov kab sib txuas. Saib xyuas qhov degradation siab rau 15 feeb. Txhua lub caij nplooj zeeg sai yog ib qho cim ntawm kev so sab hauv.
Kev kho yog yooj yim qhov twg cov dej ntws yog txwv rau lub gasket. Thaum lub tsev tau txias rau ambient, re-torque bolts nyob rau hauv lub hnub qub manufacturers qauv. Hloov lub gasket nrog lub hnab ntawv PTFE kom raug lossis tag nrho lub ntsej muag hom qhia rau kev pabcuam. Kev sim siab thib ob yuav tsum tau ua kom paub tseeb tias xoom xoom ua ntej rov ua haujlwm. Tab sis yog tias kev kuaj pom tias lub raj xau los yog lub raj xaim foob tsis ua haujlwm, kev kho los ntawm cov kws tshaj lij lossis ua tiav kev hloov pauv ntawm cov khoom sib hloov yog yuav luag tsim nyog. • PTFE hlab tsis tuaj yeem kho tau los ntawm kev vuam, nplaum lossis patching, ib qho kev kho zoo li no yuav ua tsis tiav hauv qhov chaw ua haujlwm thiab tuaj yeem tsim kev ntxhov siab ntxiv. Tsis txhob solder los yog kua nplaum PTFE raj tawg nyob rau hauv lub tshav pob, nws yuav ua tsis tau dua. Lub sijhawm no, cov chaw tsim khoom lossis tus neeg tsim khoom tsim nyog yuav tsum raug hu mus rau retube lub tsev kom tiav (yog tias lub pob tsim tso cai) lossis hloov pauv.
Ua qhov kev ntsuam xyuas zaum kawg tom qab kho lossis hloov tiav. Kuaj ob sab hydrostatically los yog pneumatically ntawm 1.5 lub sij hawm tsim siab, ces dye test los yog helium leak test los xyuas qhov tseeb. Chav tsev yuav tsum tsuas yog xa rov qab mus rau qhov kev tswj xyuas pib raws li tau teev tseg hauv cov txheej txheem commissioning txheej txheem thaum tag nrho cov kev xeem tiav thiab chav tsev tau raug tshem tawm tag nrho.
Cov txheej txheem ua kom huv si tiv thaiv cov neeg ua haujlwm, ib puag ncig thiab cov cuab yeej nyob ib sab. Nws yog ib qho tseem ceeb rau kev nyab xeeb mus sij hawm ntev kom paub thaum twg los hloov lub PTFE exchanger leaky, es tsis ua hauj lwm kho. Cov nroj tsuag tuaj yeem zam kev nce mus rau hauv cov tshuaj lom neeg tseem ceeb thiab khaws cia kev ncaj ncees ntawm cov khoom siv hluav taws xob los ntawm kev sib cais tam sim, kev tswj kom tsim nyog thiab kev kuaj xyuas tag nrho ntawm txhua qhov xav tias xau. Cov neeg khiav dej num uas ua raws li cov kev ntsuas no ua rau muaj kev kub ntxhov rau hauv kev tswj hwm, cov ntaub ntawv tshwm sim uas ua rau lub chaw ua haujlwm zoo rau xyoo tom ntej.
