A plhaub-thiab- raj kub exchangeryog ib hom kub exchanger. Vim nws qhov zoo sib txawv, nws yog tam sim no siv dav. Txawm li cas los xij, tom qab siv lub sijhawm, lub plhaub - thiab - raj cua kub exchangers yuav tsum tau muab ntxuav. Hnub no, peb yuav piav qhia txog qhov tseem ceeb ntawm kev tu lub sij hawm ntawm lub plhaub- thiab - raj kub exchangers.
Lub plhaub-thiab- raj kub exchanger, tseem hu ua lub raj-thiab- plhaub kub exchanger, yog ib tug recuperative tshav kub exchanger uas siv cov phab ntsa saum npoo ntawm lub raj bundled nyob rau hauv lub plhaub raws li lub tshav kub hloov chaw. Hom kev sib hloov cua sov no muaj cov qauv yooj yim, txhim khu kev qha, thiab tuaj yeem tsim tau siv ntau yam khoom siv. Nws tuaj yeem ua haujlwm nyob rau hauv qhov kub thiab txias siab, ua rau nws yog ib qho ntawm cov khoom siv hluav taws xob ntau tshaj plaws tam sim no.
Kev tu lub sij hawm ntawm lub plhaub- thiab- raj kub exchangers tom qab siv sij hawm yog qhov tseem ceeb heev. Feem ntau, hauv cov ntawv thov kev lag luam, tom qab siv sij hawm ntev -, cov raj sab hauv ntawm lub plhaub - thiab - raj cua kub exchangers feem ntau ua rau cov plua plav thiab sediment, uas ua raws li cov kav dej. Qhov no ua rau txo qis hauv kev sib pauv hluav taws xob, uas ua rau cov nqi tsim khoom tsis ncaj qha. Hauv qhov xwm txheej hnyav, nws tuaj yeem ua rau lub neej ua haujlwm luv luv ntawm lub plhaub- thiab - raj cua kub exchanger, ua rau poob.
Kev Ntxuav Pab Txhim Kho Thaum tshav kub kub Exchanger Efficiency
Tom qab lub plhaub- thiab- raj kub exchanger los yog nws cov hlab tau ua haujlwm rau lub sijhawm, txheej ntawm fouling feem ntau tshwm sim ntawm lawv qhov chaw. Qhov fouling no feem ntau ntom thiab tawv, nrog tsis tshua muaj thermal conductivity. Kev tiv thaiv los ntawm fouling yog qhov xav tsis thoob; Yog hais tias cov organic ions thiab plua plav uas muaj nyob rau hauv fouling tsis tau hais, lawv yuav ua rau lwm yam teeb meem uas tsis tuaj yeem zam tau.
Lub thermal tsis kam ntawm fouling yog 50-100 npaug ntawm cov qis- carbon steel thiab 200-400 npaug ntawm tooj liab. Yog li ntawd, fouling muaj feem cuam tshuam rau kev sib pauv cua sov. Thaum fouling cov ntaub ntawv ntawm cov khoom siv hluav taws xob hloov pauv, nws yuav ua rau muaj kev cuam tshuam kev hloov pauv kub: qhov nruab nrab uas yuav tsum tau txias tsis tuaj yeem txias kom zoo, thiab qhov nruab nrab uas yuav tsum tau ua kom sov tsis tuaj yeem ua kom sov txaus. Qhov txo qis hauv kev hloov pauv hluav taws xob yuav ua rau kom muaj kev noj cov cua sov los yog hluav taws xob, ncaj qha nce nqi ntau lawm thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom siv. Vim li no, cov cuab yeej siv hluav taws xob sib pauv yuav tsum tau ntxuav tsis tu ncua kom tshem tawm cov fouling thiab txhim kho nws cov kev sib pauv cua sov.
Hauv cov ntsiab lus, kev ntxuav lub plhaub-thiab- raj kub exchangers tsis tsuas yog txuas lub neej kev pab cuam ntawm lub tshav kub exchanger thiab txo cov nqi siv, tab sis kuj, tseem ceeb tshaj, xyuas kom meej tias lub tshav kub exchanger efficiency ntawm lub plhaub - thiab - raj kub exchanger yog tag nrho exerted. Yog li ntawd, tom qab ib lub sij hawm ntawm kev siv, ntxuav lub plhaub - thiab - raj ( raj- thiab - plhaub) cov cua kub exchangers yog ib qho teeb meem uas yuav tsum tau ua tiag tiag.
Tsis paub meej tias qhov tshwj xeeb tshwj xeeb ntawm cov khoom siv hluav taws xob sib txuas nrog koj cov txheej txheem ntws? Tiv tauj peb -peb pab neeg tshaj lij yuav pom zoo cov kev qhia tshwj xeeb raws li koj qhov nruab nrab tsis, kev thauj mus los ntawm tshav kub, thiab chaw teeb tsa, thiab muab cov ntaub ntawv zoo sib xws.
