Qhov zoo ntawm Plate Heat Exchangers
Los ntawm kev tshawb fawb thiab kev xyaum tsim khoom, tib neeg muaj kev nkag siab tob txog cov yam ntxwv ntawm cov phaj kub hloov pauv, thiab suav nrog cov txiaj ntsig zoo thiab qhov tsis zoo, feem ntau piv nrog cov raj cua kub exchangers, uas tuaj yeem ua tiav raws li cov ntsiab lus hauv qab no:
Lub ntsiab kom zoo dua
1: High heat transfer coefficient
Cov qauv ntawm lub plhaub thiab lub raj cua kub exchanger yog zoo nyob rau hauv cov nqe lus ntawm lub zog, tab sis nws tsis yog zoo tagnrho nyob rau hauv cov nqe lus ntawm tshav kub exchanger, vim hais tias thaum cov dej ntws nyob rau hauv tus txheej txheem, muaj baffle-baffle thiab baffle-pauv Bypass ntawm cov kav dej kub thiab cev bund. Cov kua dej dhau los ntawm cov bypasses no tsis koom nrog kev sib pauv cua sov. Nyob rau hauv lub phaj kub exchanger, tsis muaj bypass, thiab corrugation ntawm lub phaj yuav ua rau cov kua turbulent ntawm ib tug me me txaus tus nqi. Yog li ntawd, lub phaj kub exchanger muaj ntau dua kub hloov coefficient, uas feem ntau yog 3 npaug ntawm lub plhaub thiab lub raj kub exchanger.
2: Loj logarithmic txhais tau tias kub sib txawv
Nyob rau hauv lub plhaub thiab lub raj cua kub exchanger, ob lub kua yog ntws nyob rau hauv lub plhaub sab thiab lub raj sab, uas feem ntau yog ib tug cross-flow flow hom. Yog tias kev tshuaj xyuas ntxiv, lub plhaub sab yog qhov sib xyaw ua ke, thiab lub raj sab yog ntau qhov dej ntws, yog li lub logarithmic nruab nrab qhov kub sib txawv yuav tsum siv qhov kho kom raug. Kev kho coefficient feem ntau yog me me - qhov ntws ntawm cov kua hauv lub phaj kub hloov pauv feem ntau yog qhov sib txuam tam sim no lossis counter-tam sim no, thiab qhov kub sib txawv kho coefficient feem ntau ntau dua 0.8, feem ntau yog {{7} }.95 ib.
3: Me hneev taw
Lub phaj kub exchanger muaj ib tug compact qauv, thiab lub tshav kub exchanger nto nyob rau hauv lub chav tsev lub cev yog 2 mus rau 5 npaug ntawm lub plhaub thiab lub raj kub exchanger. Rau tib lub tshav kub pauv ua hauj lwm, pem teb cheeb tsam ntawmlub phaj kub exchanger yog hais txog 1/5 ~ 1/10 ntawm lub raj kub exchanger.
4: Lub teeb nyhav
Lub thickness ntawm lub phaj kub exchanger tsuas yog {{0}}.6 ~ 0.8 hli, thiab lub thickness ntawm lub tshav kub exchanger raj ntawm lub raj kub exchanger yog 2.0 ~ 2.5 hli: lub plhaub ntawm lub plhaub thiab lub raj cua kub exchanger yog hnyav dua li tus ncej ntawm lub phaj kub exchanger. ntau. Nyob rau hauv cov ntaub ntawv ntawm ua tiav tib lub tshav kub exchanger, lub tshav kub exchanger cheeb tsam yuav tsum tau los ntawm lub phaj kub exchanger yog me dua li ntawm lub raj kub exchanger.
5: tus nqi qis
Raws li kev siv cov khoom siv tib yam, vim tias cov thav duab yuav tsum muaj cov khoom siv tsawg dua, cov nqi tsim khoom yuav tsum qis dua li ntawm lub plhaub thiab lub raj cua kub exchanger.
6: Qhov kawg kub qhov sib txawv me me
Nyob rau hauv lub plhaub thiab lub raj cua kub exchanger, cov kua ntws nyob rau hauv lub plhaub sab thiab lub tshav kub exchanger nto yog staggered thiab ntws nyob ib ncig ntawm, thiab kuj muaj ib sab ntws, thaum lub ntws ntawm cov dej txias thiab kub nyob rau hauv lub phaj kub exchanger. phaj kub exchanger yog parallel mus rau lub tshav kub exchanger. Ntxiv mus, tsis muaj bypass ntws, yog li ntawd qhov kub ntawm qhov kawg ntawm lub phaj kub exchanger yog heev me me, thiab lub tshav kub exchanger ntawm dej thiab dej yuav tsum tau qis dua 1 degree, thaum lub raj kub exchanger yog hais txog 5 degree, uas yog ib qho tseem ceeb heev rau absorbing tsawg-theem tshav kub zog. Muaj txiaj ntsig heev.
7: Tsawg fouling coefficient
Lub fouling coefficient ntawm phaj kub exchanger yog ntau me dua li ntawm lub raj kub exchanger. Yog vim li cas yog tias cov kua dej ua rau muaj kev kub ntxhov, thiab cov impurities yuav tsum tsis txhob muab tso rau: qhov chaw tuag ntawm cov channel ntawm cov phiaj yog me me: cov cua kub sib hloov ua los ntawm cov hlau tsis huv yog du thiab du. Thiab tsawg dua corrosion deposits, thiab yooj yim los ntxuav.
8: tshav kub pauv ntawm ntau yam xov xwm
Yog tias lub phaj kub hloov pauv tau nruab nrog nruab nrab baffles, ib qho khoom siv tuaj yeem ua cov khoom siv hluav taws xob sib pauv ntawm peb lossis ntau tshaj tawm.
9: Yooj yim los ntxuav
Tom qab lub phaj nias ntawm lub phaj kub exchanger raug tshem tawm, lub phaj ntim tuaj yeem raug tso tawm, cov phaj tuaj yeem raug tshem tawm, thiab kev tu txhua yam tuaj yeem ua tau.
10: Nws yog ib qho yooj yim los hloov lub tshav kub pauv saum npoo los yog txheej txheem ua ke
Nws tsuas yog yuav tsum tau nce (lossis txo) cov phiaj kom ua tiav qhov chaw sib pauv cua sov uas yuav tsum tau nce (lossis txo).
Daim ntawv thov kev tsim khoom
Lub tuam txhab lub luag haujlwm tseem ceeb suav nrog: kev saib xyuas huab cua hauv nruab nrab, kev tu thiab kev pabcuam; cua txias ntauwd thiab kiv cua coil tu thiab tu cov kev pabcuam; kev cai ua cov tshuaj lithium bromide; muag ntawm lithium bromide tov tshwj xeeb impurity separators; central cua txias party thiab ntau yam xoom Muag khoom accessories; installation thiab muag khoom ntawm central cua txias tshuab, thiab lwm yam.
Siv dav hauv cov tshuab cua txias thiab cov txheej txheem txias txias thiab cua sov; nyob rau hauv steel, textile, tshuaj, electronics, tshuaj, khoom noj khoom haus thiab lwm yam industrial thiab mining enterprises, raws li zoo raws li cov tsev so, theaters, tsev kho mob, thiab loj coj mus muag vaj tse, Central cua sov chaw nres tsheb thiab lwm lub sij hawm yog dav siv.
