Yuav ua li cas ntxuav ib tug hnyav fouled PTFE Exchanger siv ib tug Recirculating ua npuas ncauj ntxuav txoj kev?

Lub PTFE lub tshuab hluav taws xob tuaj yeem ua rau hnyav heev nrog cov khoom siv polymerized organic uas tsis tuaj yeem ua rau kev ntxuav ib txwm. Ib qho yooj yim ua kua ntxhua feem ntau tsis txaus raws li txoj kev ntws nyiam tshaj tawm los ntawm cov chaw qhib thiab hla qhov chaw uas muaj kuab lom ntau tshaj plaws. Ua npuas ncauj-raws li kev tu xyuas hloov qhov kev nyiam no los ntawm kev sau lub peev xwm ntawm cov khoom sib pauv nrog cov tshuaj ua haujlwm ruaj khov ua npuas ncauj uas tuav lub sijhawm ntev nrog cov chaw fouled siv qhov ntim tsawg kawg nkaus ntawm cov kua.

Txoj kev ua npuas dej rau fouled PTFE exchanger tau pom tias yog ib qho kev xaiv tiag tiag rau cov kab mob sib kis loj heev, tshwj xeeb tshaj yog thaum muaj kev tiv thaiv zoo thiab kev siv tshuaj lom neeg tsawg yog qhov tseem ceeb.

Vim li cas cov dej ntws zoo tib yam tsis ua haujlwm nrog hnyav fouling
Hnyav PTFE exchangers feem ntau nthuav tawm:

Cov yeeb yaj kiab tuab ntawm cov organic polymers

Cov nplaum nplaum -zoo li cov residues

Kev thaiv ib nrab lossis tag nrho channel

Kev faib tawm tsis sib xws

Ua Kua Ntxuav Channeling nyhuv
Thaum lub sij hawm ib txwm ua kua dej ntws:

Flow yuav siv txoj hauv kev tsawg kawg nkaus.

Feem ntau ntawm cov kua txav mus los ntawm cov kab qhib.

Cov cheeb tsam fouled tseem tsis cuam tshuam ntau

Qhov no ua rau kev tu tsis tiav thiab lub voj voog ntawm kev kho dua tshiab.

Yuav Ua Li Cas Foam Cleaning Recirculates
Kev ntxuav siv ua npuas dej hloov cov kua ua kua ntau nrog cov pa roj- cov kua sib tov uas ua rau cov khoom sib pauv sib npaug.

Ua npuas ncauj txheej txheem
Ib tug raug system tej zaum yuav muaj xws li:

Ntxuav tshuaj siv raws li hom foulant

Polymerized lipids nyob rau hauv heev alkaline daws

Cov tshuaj acidic rau kev tshem tawm cov nplai

Cov kuab tshuaj-raws li tar thiab hydrocarbon systems

PTFE, gaskets, thiab cov khoom siv tsim nyog foaming tus neeg sawv cev

Foaming Wand lossis Foam Generator

Cycle twj tso kua mis system

Cov tshuaj yog ces aerated los ua ib tug tuab, ruaj khov ua npuas ncauj nrog lub sib xws ntawm shaving cream.

Txhaj rau hauv Exchanger

Lub plhaub sab los yog lub raj sab (nyob ntawm qhov chaw ntawm fouling)

Ib tug kiag li drained, cais system

Vim tias feem ntau ntawm cov npuas dej yog roj:

Yuav tsum muaj kua ntim tsawg heev

tag nrho internal ntim yog uniformly sau

Mechanism ntawm Ua Npuas Ncauj Ntxuav hauv Fouled PTFE Systems
Thaum nyob rau hauv lub exchanger lub npuas yog ib tug dynamic tu nruab nrab.

Sib cuag thiab Adhesion ntawm Nto
Ua npuas ncauj:

Adheres rau ob qho tib si ntsug thiab kab rov tav nto

Sau thaj chaw tsis muaj sia thiab thaj chaw sluggish

Tsis tog vim nws tsis ntom

Ua npuas ncauj yog ib daim pam chemical uas suffocates lub fouling los ntawm lo rau nws.

Collapsing Action thiab tsis tu ncua ntub dej
Raws li lub froth maj mam collapses:

tas li tso cov tshuaj ntxuav tshiab

Rov ua dua - ntub dej ntawm fouling txheej

Maximizing lub sij hawm ntawm cov tshuaj tiv thaiv

Kev sib kis qeeb qeeb yog tus yuam sij rau kev rhuav tshem cov pob zeb tuab.

Theem ntawm Soaking thiab Recirculation
Nyob rau hauv ib tug recirculating ua npuas ncauj system:

Ua npuas ncauj rov ntxiv tas li lossis tsis xwm yeem.

Qhov tseem ceeb ncua sij hawm sib cuag

Txhim kho chemical efficiency

Soak lub sij hawm feem ntau optimized raws li:

Fouling thickness

Tshuaj muaj zog

Kub ntawm cov tshuaj ntxuav

Hom Pollutant

Yaug & Tshem Tawm Theem
Tom qab lub voj voog tu:

Siv npuas yog muab rho tawm los ntawm lub exchanger

Nws siv lub siab - dej nrawm nrawm

Dissolved thiab softened residues yog ntxuav tawm

Qhov zoo ntawm PTFE Surface Properties
Cov kauj ruam no tau txais txiaj ntsig zoo los ntawm PTFE:

Lub zog ntawm lub zog qis txhais tau tias adhesion qis dua

Fouling yog tso tawm yooj yim dua thaum softened

Txiav cov yeeb yaj kiab seem

Qhov no txhim kho kev tu tag nrho thiab txo qhov kev xav tau ntawm kev siv tshuab.

Chemical Compatibility Requirements
Ua npuas ncauj ntxuav tshuab yuav tsum tau tsim nrog kev saib xyuas kom lawv sib haum nrog cov khoom siv.

Cov khoom txwv
Cov tshuaj ntxuav thiab foaming additives yuav tsum tau sib xws nrog:

PTFE tube nto

Hlau Tubesheets thiab Plhaub

Gaskets thiab seals, elastomeric

Chemistry tshwj xeeb rau Foulants
Kev xaiv cov tshuaj raug cai yog qhov tseem ceeb:

Alkaline daws rau kev tsim cov organic polymers

Acid daws rau inorganic nplai.

Hydrocarbon tar & resin hnyav systems

Xaiv qhov tsis ncaj ncees lawm chemistry tuaj yeem ua haujlwm tsawg dua lossis ua rau cov khoom puas hauv lub cev.

Kev txo qis & kev ua haujlwm tau zoo
Ib qho txiaj ntsig loj ntawm kev ua npuas dej yog siv cov tshuaj tsawg dua.

Tsawg Volume Liquid Xav Tau
Vim tias ua npuas ncauj yog huab cua:

Yuav tsum muaj tshuaj lom neeg tsawg dua

Txo lub nra ntawm pov tseg neutralization

Cov kev siv pov tseg raug txo kom tsawg.

Qhov no ua rau ua npuas ncauj ntxuav tshwj xeeb tshaj yog txaus nyiam rau cov khoom lag luam loj loj.

Kev txiav txim siab tsim qauv
Kev npaj kom zoo yog qhov tseem ceeb rau kev ua npuas dej kom zoo.

Kev rho tawm thiab tso dej tawm
Ua ntej ntxuav:

Exchanger yuav tsum tau sib cais tag nrho.

Ua kom tiav cov kua dej dawb

Kev faib ua npuas ncauj yuav tsum qhib txoj hauv kev

Uniform Distribution of Foam
Uniform coverage yog nyob ntawm:

Kho qhov tso nkag nkag

Tswj pace ntawm npuas expansion

Txawm tias muaj kev sib kis

Kev faib tawm tsis zoo tuaj yeem ua rau thaj chaw hauv qab - ntxuav.

Xaus
Kev ntxuav ua npuas ncauj yog qhov muaj zog, qis - ntim thiab ua tau zoo heev ntawm kev tshem tawm cov organic fouling hnyav los ntawm PTFE cov khoom siv hluav taws xob. This is accomplished by filling the exchanger with a dense, chemically active foam providing long contact periods and a minimum of total cleaning solution required.

Cov ua npuas ncauj tu fouled PTFE exchanger mus kom ze yog qhov zoo qhov twg cov pa dej ntws tawm tsis yog, los ntawm kev nkag mus rau qhov chaw tuag, ua rau cov duab nyuaj thiab ua kom muaj kev sib cuag nrog cov fouling txheej. Qhov no zoo heev txhim kho kev tu kom zoo thiab txo qis sijhawm rau kev txij nkawm.

Hauv cov tshuab fouled tsis tshua muaj, txoj kev tu zoo tshaj plaws yog feem ntau ib qho uas tuaj yeem zam lub ntiajteb txawj nqus, ua raws txhua qhov chaw thiab maj mam yaj cov kab mob hauv qhov chaw, es tsis txhob sim yuam kom nws tawm ntawm cov dej ntau.
