Yuav ua li cas yog PTFE Thaum tshav kub kub Exchangers siv nyob rau hauv Pickling kab rau carbon hlau?

Carbon steel pickling kab siv ntau lub zog los ua kom sov cov kua qaub da dej thiab yaug dej. Feem ntau ntawm cov cua sov no poob rau hauv qhov ntws thaum cov dej kub yaug tawm. Cov hluav taws kub pov tseg no tuaj yeem rov qab tau siv lub tshuab hluav taws xob PTFE, txuag lub zog thiab tiv taus qhov corrosive thiab acidic ib puag ncig.

Steel Pickling Txheej Txheem & Lub Sijhawm rau Kev Kub Kub Rov Qab
Pickling yog cov txheej txheem tseem ceeb hauv kev ua cov nroj tsuag steel rau kev tshem tawm zeb nplai los ntawm cov hlau. Qhov ntsuas no yog los ntawm - cov khoom ntawm cov txheej txheem kub dov thiab nws yuav tsum tau muab tshem tawm ua ntej ua tiav lossis txheej txheej. Pickling Cov hlau yog immersed nyob rau hauv ib da dej ntawm hydrochloric los yog sulfuric acid. Lub da dej yog rhuab mus rau 60-90 degree. Lub zeb nplai yog yaj. Cov dej kub yaug cov hlau kom tshem tawm cov kua qaub tshuav tom qab kho cov kua qaub.

Cov dej yaug, uas feem ntau yog rhuab mus rau 70-90 degree, muaj me ntsis acid thiab yaj hlau los ntawm pickling. Cov dej no feem ntau yog nkim, nqa nrog nws ntau lub zog kub. Qhov xwm txheej corrosive ntawm cov dej yaug tuaj yeem ua rau cov khoom siv hluav taws xob puas sai sai thiab feem ntau ua rau cov txheej txheem cua sov rov qab tsis zoo. Cov dej khib nyiab no tuaj yeem rov qab tau, txawm li cas los xij, thiab xa mus rau cov dej tshiab los ua ntej nws nkag mus rau hauv lub tank los yog cov kua qaub da dej siv lub PTFE kub exchanger.

PTFE Thaum tshav kub kub Exchanger: Cov lus teb rau cua sov rov qab
Thaum tshav kub kub rov qab yog kev lag luam zoo nkauj nyob rau hauv cov hlau pickling ib puag ncig PTFE tshav kub exchanger recovers khib nyiab los ntawm cov dej kub yaug thiab siv nws los ua kom sov cov dej los, yog li txiav txim siab lub zog xav tau los tswj lub tank ntawm qhov kub thiab txias. PTFE heat exchangers yog zoo suited rau daim ntawv thov no vim lawv muaj peev xwm tiv taus acidic thiab corrosive xwm ntawm pickling kab.

Cov kua qaub concentration (1-2%) nyob rau hauv cov dej yaug yog tsis txaus ua rau corrosion ntawm carbon steel los yog stainless hlau lub sij hawm. Tab sis cov ntaub ntawv no yuav inevitably tawg nyob rau lub sij hawm ntev. PTFE, txawm li cas los xij, muaj kev tiv thaiv zoo rau ob qho tib si hydrochloric thiab sulfuric acids thiab yuav yog ib qho khoom siv zoo tshaj plaws rau lub tshav kub exchanger hauv qhov chaw no. PTFE tsis yog-corrosive thiab yog li ntawd tuaj yeem rov qab tau cov cua sov zoo yam tsis muaj kev ntshai ntawm degradation los yog paug.

PTFE cov khoom siv hluav taws xob feem ntau yog siv rau hauv lub plhaub thiab lub raj tsim qhov chaw uas cov dej kub yaug mus los ntawm cov raj sab hauv thiab cov dej tshiab tuaj dhau los ntawm lub plhaub ib puag ncig. Qhov kev tsim no ua rau muaj kev hloov pauv mus rau qhov kub tsis muaj kev sib cuag ncaj qha ntawm ob lub kua dej.

Hom Installation Counter Flow Heat Recovery Loop
Pickling kab PTFE tshav kub exchangers feem ntau ntiav ib tug yooj yim counterflow tshav kub rov qab voj. Nyob rau hauv no configuration, cov dej kub yaug nkag mus rau lub tshav kub exchanger thiab ntws counter rau cov dej tshiab tuaj. Raws li ob lub kwj dej hla ib leeg, cov cua sov kis tau los ntawm cov dej kub yaug mus rau cov dej txias nkag. Qhov kev tsim no yuav yog qhov zoo tshaj plaws rau kev hloov cua sov, preheating cov dej nkag mus rau qhov zoo tshaj plaws kub ua ntej nws mus txog lub tank yaug.

Lub kaw lus rov ua kom sov los ntawm cov dej kub yaug kom txo qis lub zog xav tau ntawm lub tshuab rhaub dej kub, yog li txo qis tag nrho lub zog siv thiab kev siv nyiaj. PTFE heat exchangers tsis tsuas txuag lub zog, lawv kuj txo cov thermal load ntawm cov dej khib nyiab vim hais tias tsawg zog yog pub rau hauv cov dej khib nyiab.

Qhov zoo ntawm PTFE Heat Exchangers hauv Pickling Kab
PTFE heat exchangers muaj ntau yam txiaj ntsig tseem ceeb rau carbon steel pickling kab:

Kev siv hluav taws xob qis: PTFE cov khoom siv hluav taws xob txo qis ntawm lub zog uas xav tau los khaws cov tso tsheb hlau luam ntawm qhov kub thiab txias los ntawm kev ntes thiab rov- siv cov dej kub yaug.

Lub Sijhawm Them Nyiaj Them Nqi Them Nqi Them ntawm lub tshuab hluav taws xob PTFE feem ntau muaj lub sijhawm them rov qab luv luv - feem ntau ntawm 12 thiab 18 lub hlis - vim yog lub zog txuag.

Corrosion Resistance: PTFE yog resistant rau hydrochloric thiab sulfuric acids yog li lub tshav kub exchanger yuav ua hauj lwm zoo yam tsis muaj kev pheej hmoo ntawm corrosion thiab ib tug ntev kev pab cuam lub neej tshaj hlau tshav kub exchangers.

Txo kev thauj khoom ntawm kev kho dej khib nyiab: PTFE cov khoom siv hluav taws xob ua kom txias cov dej khib nyiab, yog li txo cov load ntawm cov chaw kho dej khib nyiab thiab siv lub zog tsawg dua rau kev ua kom txias thiab kho ntxiv.

Xaus
PTFE heat exchangers yog ib txoj kev ua tau zoo thiab muaj peev xwm ntawm cov khoom pov tseg thaum tshav kub kub rov qab rau hauv qhov chaw corrosive ntawm steel pickling cog. Cov khoom siv hluav taws xob no rov qab tau ntau lub zog los ntawm kev rho tawm cov cua sov los ntawm cov dej kub yaug thiab xa mus rau cov dej tshiab, yog li tsis muaj cua sov ntxiv. PTFE qhov kev tiv thaiv corrosion muab kev ua haujlwm ntev - lub sijhawm ua haujlwm nyob rau hauv ib puag ncig cov kua qaub, thaum lub tshav kub rov qab los pab txo cov nuj nqis ua haujlwm thiab ib puag ncig. Lub zog efficiency thiab corrosion kuj yog ib qho tseem ceeb ua ke rau kev ruaj ntseg thiab nqi- kev ua haujlwm zoo hauv kev ua hlau.
