Vim lubphaj kub exchangertsis tshua muaj siab hloov hluav taws xob efficiency thiab nqi-zoo, nws yog tam sim no dav siv nyob rau hauv ntau yam industries, thiab yog ib tug heev heev tshav kub exchanger. High heat transfer coefficient, logarithmic nruab nrab kub qhov sib txawv, me me hneev taw, lub teeb yuag, tsis tshua muaj nqi, me me kub qhov sib txawv ntawm qhov kawg, tsis tshua muaj fouling coefficient, yooj yim los ntxuav, yooj yim los hloov lub tshav kub hloov chaw thiab cov txheej txheem ua ke, thiab lwm yam., cov no yog cov qhov zoo ntawm cov phaj kub exchanger. Yog li nyob rau hauv cov khoom ua hauj lwm phaj kub exchanger tsis ua hauj lwm, peb yuav tsum daws nws li cas? Cov txheej txheem daws teeb meem yog dab tsi? Cia peb tshawb nrhiav.
Ua ntej, qhov ua tsis tiav ntawm phaj kub exchanger
1. Media leakage
Daim Ntawv I: kev xau, xau thaum cov xov xwm tsis loj, thiab tsis txuas ntxiv;
Daim ntawv thib ob: kev xau, xau ntawm cov xov xwm loj dua, thiab xov xwm txuas ntxiv.
Kev xau tshwm sim feem ntau nyob rau hauv lub foob ntawm lub phaj, phaj kawg thiab compression phaj sab hauv thiab phaj corrugated groove qhov chaw.
2. Media inlet thiab qhov hluav taws xob siab sib txawv yog loj
Lub qhov hluav taws xob tawm qhov hluav taws xob me me dhau lawm, lub siab poob qis tshaj qhov kev tsim qauv, cuam tshuam ncaj qha rau lub tshuab hluav taws xob hloov hluav taws xob, thiab tsis tuaj yeem ua tau raws li qhov system ntws thiab kub. Tsis tuaj yeem ua lub luag haujlwm ntawm cua sov (lossis txias) nruab nrab.
3. Media mixing
Manifested raws li qhov siab dua sab ntawm qhov nruab nrab sib xyaw rau hauv qhov qis qis ntawm qhov nruab nrab, yuav muaj qhov txawv txav thiab siab. Yog hais tias qhov nruab nrab yog corrosive, tab sis kuj ua rau corrosion ntawm lwm yam khoom nyob rau hauv lub system. Feem ntau tshwm sim nyob rau hauv lub thib ob sealing cheeb tsam los yog inflow cheeb tsam. Cov nyhuv txias tsis pom tseeb. Lub ntsiab feature yog tias qhov hluav taws xob qhov hluav taws xob ntawm qhov cua txias nruab nrab yog siab, thiab tsis yog raws li qhov yuav tsum tau tsim.
Thib ob, lub phaj kub exchanger txoj kev daws teeb meem
Ntxiv regenerative cua txias system
Lub thiaj li hu ua regenerative txias system yog tib cov kua hauv lub phaj kub exchanger ntawm lub ntshuam thiab export pipeline ntxiv piping thiab li qub, thiab tom qab ntawd los ntawm kev hloov lub valve los hloov cov kev taw qhia ntawm ntws ntawm ob lub kua, kom lub backwash kom tshem tawm. lub tsub zuj zuj ntawm impurities ntawm lub phaj. Ua ntej kev hloov pauv ntawm cov txheej txheem ib txwm muaj kuj yog qhov hloov pauv ntawm cov dej ntws tawm ntawm qhov kaw ntawm cov valve ntxiv thaum cov txheej txheem ib txwm muaj, tom qab kev hloov pauv ntawm cov txheej txheem rov qab, kuj yog qhov hloov pauv ntawm cov dej ntws tawm ntawm cov khoom qub thiab. export li qub, qhib cov valve ntxiv thaum txheej txheem rov qab ntxuav. Los ntawm cov dej ntws ntawm cov dej thiab cov roj lubricating los ntawm lub phaj kub exchanger ntawm ob lub tshav kub hloov pauv cov kav dej hloov pauv, ntawm lub tshuab hluav taws xob nws tus kheej, cov txheej txheem ib txwm muaj thiab cov txheej txheem rov qab ua haujlwm ob yam tsis muaj qhov sib txawv, yog li lub phaj kub hloov pauv hauv qhov qub. kev ua haujlwm ntawm cov txheej txheem kom txo tau cov impurities ntawm lub phaj nruab nrab ntawm kev txhaws ntawm cov channel.
Cov lim dej ntxiv ntawm cov dej ntws tawm
Nyob rau hauv lub phaj kub exchanger circulating dej inlet pipeline ntxiv ib tug nplua lim nruab nrog ib tug thib ob lim thiab cov sub-line sib raug zoo, thiab tsis tu ncua siv lub sub-line lag luam, tshem tawm cov lim ntawm lub lim zoo rau tu, zoo tiv thaiv cov packing khib nyiab thiab lwm yam impurities rau hauv lub tshav kub exchanger.
Kev tu ncua kev puas tsuaj
Phaj heat exchanger disintegration phaj kub exchanger tuaj yeem npaj los ntawm kev saib xyuas qhov xwm txheej thiab lub sijhawm xav tau rau kev saib xyuas ntawm qhov chaw disintegration lossis tag nrho disintegration thiab hoisted mus rau qhov chaw tsim nyog ua ntej disintegration txij nkawm. Ua ntej disassembling, ua ntej siv daim kab xev ntsuas kom ua tib zoo ntsuas qhov kev ncua deb ntawm ob daim hlau compression B tus nqi, kom ib qho khoom seem, thiab tom qab ntawd siv tus ciaj ntswj los tuav cov txiv ntoo los ntawm qhov kev txiav txim ntawm kab pheeb ces kaum sib koom ua ke xoob, thiab tom qab ntawd tshem tawm cov clamping. ntsia hlau, thiab tom qab ntawd cov kev ua ntawm lub phaj compression mus rau qhov kawg ntawm kem, thiab tom qab ntawd lub phaj los txhawb lub phaj rau lub phaj kom txav mus rau sab saum toj ntawm qhov kev taw qhia bar, pem hauv ntej lossis sab nraub qaum. tawm ntawm lub phaj.
Ntxuav thiab tiv thaiv lub phaj
Ua kom lub phaj huv huv yog ib qho tseem ceeb rau kev tswj xyuas qhov kub hloov pauv coefficient ntawm phaj kub exchanger. Nyob nruab nrab ntawm daim hlau, qhov nruab nrab yog raws qhov nqaim zigzag channel txav, txawm tias cov khoom tsis tuab tuab ntawm cov nplai, yuav ua rau muaj kev hloov pauv loj hauv txoj kev ntws, cuam tshuam rau kev txav ntawm cov kua dej, kom lub siab poob siab. , lub tshav kub hloov coefficient txo. Rau cov av dav dav, kev siv cov tshuaj ntxuav tu los yog kev siv tshuab (lub cev) kev tu yuav ua tau, thiab rau cov av tuab tuab, nws yog ib qho tsim nyog yuav tsum tau siv cov tshuaj ntxuav thawj zaug kom soften lub nplai txheej, thiab tom qab ntawd tshuab (lub cev) txoj kev tu kom tshem tawm cov nplai txheej ntawm cov txheej txheem kev sib xyaw ua kom huv huv kom huv si kom huv si thiab huv si.
Raws li kev siv phaj kub exchanger circulating dej sab ntawm cov yam ntxwv av, cov hauv qab no txoj kev:
ib. Kev ntxuav ntawm txawv teb chaws impurities thiab deposits: mechanical (lub cev) tu txoj kev, nrog mos txhuam thiab dej rau phau ntawv txhuam.
b. Hard tuab txheej ntawm tu nplai: raws li cov lus qhia tshwj xeeb ntawm lub phaj ua kom muaj qhov chaw sab hauv ntawm 1200 × 350 × 500mm dab dej, yuav tsum tau muab tshem tawm mus rau hauv lub qhov, ntawm chav tsev kub nrog 5% ntawm nitric acid tov 8h los yog li ntawd, ntses tawm nrog txhuam mos thiab dej huv tuaj yeem ntxuav. Tau kawg, qhov kev ntsuas tsis yog lub phaj loj heev, los yog vim muaj kev txwv lub sij hawm tsis tuaj yeem siv los ua kev tu kom huv, nrog rau cov hlau tsis muaj steel hlau txhuam lossis stainless hlau ntxuav pob, thiab dej txhuam, tuaj yeem ntxuav lub phaj. .
Phaj sealing groove tu
Phaj kub exchanger sealing gasket yog ib feem tseem ceeb, feem ntau ntawm Tuam Tshoj cov nplaum gasket muab tshuaj txhuam rau hauv cov phaj gasket zawj "paste hom" sealing qauv. BR02 hom phaj kub exchanger sealing gasket thiab phaj nruab nrab ntawm cov nplaum rau kev sib txuas cov yas thiab roj hmab 401 instantaneous qhuav nplaum, nws yog nrog cov stainless hlau phaj ua ke lub zog ntawm nruab nrab. Nruab nrab. Hloov cov gasket, daim ntawv phaj tiaj tiaj rau ntawm lub phaj tiaj tus, nrog rau lub hau ntswj kom cock lub gasket, maj mam rub tawm. Rau cov roj hmab residual nyob rau hauv lub gasket zawj, siv ib tug stainless hlau xaim txhuam los yog stainless hlau ntxuav pob nrog acetone ua tib zoo thiab maj mam txhuam, thiab ces yaug nrog dej.
Kev tshuaj xyuas ntawm lub phaj
Cov phaj ntxuav yuav tsum nruj me ntsis macro-kev tshuaj xyuas ntawm txhua daim, yog tias tsim nyog, thiab tom qab ntawd translucent, xim lossis nkag mus kuaj, ib lub phaj yuav tsis muaj qhov tsis xws luag hauv qab no:
ib. Qhov saum npoo tsis pub muaj qhov pits, khawb, indentations, burrs, thiab lwm yam uas tshaj qhov thickness kam rau ua;
b. Qhov tob ntawm corrugation thiab gasket groove qhov sib txawv ntawm qhov tob yuav tsum tsis pub ntau tshaj ± 0.1mm;
c. Tsis yog lub phaj kub exchanger ib feem los yog lub sealing groove yuav tsum muaj corrosion perforations los yog tawg, yog hais tias lub phaj kub exchanger ib feem muaj perforations los yog tawg, nws yuav kho tau los ntawm argon arc vuam nrog ceev faj vuam thiab sib tsoo.
Cov ntsiab lus
Phaj tshav kub exchanger feem ntau tsis ua hauj lwm ntawm kev tshaj tawm tawm, xov xwm inlet, thiab qhov hluav taws xob siab sib txawv, xov xwm sib xyaw, thiab cov nyhuv txias tsis pom tseeb hauv plaub hom. Kev kho dua tshiab, thiab cov txheej txheem tsim kho tuaj yeem tiv thaiv kom tsis txhob muaj cua sov tsis ua haujlwm, kom ntseeg tau tias muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov khoom siv hluav taws xob. Nthuav cov tshav kub hloov chaw ntawm lub tshav kub exchanger, ua kom lub tshav kub hloov lwm lub tsev kub sib txawv, txhim kho lub tshav kub hloov coefficient yuav ntxiv dag zog rau lub tshav kub hloov ntawm cov khoom siv hluav taws xob.
